Shanghai Jiao tong University, China with finite element analysis of metal plastic forming systems and Die CAD / CAM systems; Beijing Beihang Haier Software Ltd. CAXA Series software; Jilin Gold Grid Engineering Research Center of the stamping die mold CAD / CAE / CAM systems . (2) Mold design, analysis and manufacture of three-dimensional Two-dimensional mold of traditional structural design can no longer meet modern technical requirements of production and integration. Mold design, analysis, manufacturing three-dimensional technology, paperless software required to mold a new generation of three-dimensional, intuitive sense to design the mold, using three-dimensional digital model can be easily used in the product structure of CAE analysis, tooling manufacturability evaluation and CNC machining, forming process simulation and information management and sharing. Such as Pro / ENGINEER, UG and CATIA software such as with parametric, feature-based, all relevant characteristics, so that mold concurrent engineering possible. In addition, Cimatran company Mold expert, Delcam's Ps-mold and Hitachi Shipbuilding of Space-E/mold are professional injection mold 3D design software, interactive 3D cavity, core design, mold base design configuration and typical structure . Australian company Moldflow realistic three-dimensional flow simulation software MoldflowAdvisers been widely praised by users and applications. China Huazhong University of Science have developed similar software HSC3D4.5F and Zhengzhou University, Z-mold software. For manufacturing, knowledge-based intelligent software function is a measure of die important sign of advanced and practical one. Such as injection molding experts Cimatron's software can automatically generate parting direction based parting line and parting surface, generate products corresponding to the core and cavity, implementation of all relevant parts mold, and for automatically generated BOM Form NC drilling process, and can intelligently process parameter setting, calibration and other processing results. (3) Mold software applications, networking trend With the mold in the enterprise competition, cooperation, production and management, globalization, internationalization, and the rapid development of computer hardware and software technology, the Internet has made in the mold industry, virtual design, agile manufacturing technology both necessary and possible. The United States in its "21st Century Manufacturing Enterprise Strategy" that the auto industry by 2006 to achieve agile manufacturing / virtual engineering solutions to automotive development cycle shortened from 40 months to 4 months. 2. mold testing, processing equipment to the precise, efficient, and multi-direction (1) mold testing equipment more sophisticated, efficient Sophisticated, complex, large-scale mold development, testing equipment have become increasingly demanding. Precision Mould precision now reached 2 ~ 3μm, more domestic manufacturers have to use Italy, the United States, Japan and other countries in the high-precision coordinate measuring machine, and with digital scanning. Such as Dongfeng Motor Mould Factory not only has the capacity 3250mm × 3250mm Italian coordinate measuring machine, also has a digital photography optical scanner, the first in the domestic use of digital photography, optical scanning as a means of spatial three-dimensional access to information, enabling the establishment from the measurement of physical → model output of engineering drawings → → the whole process of mold making, reverse engineering a successful technology development and applications. This equipment include: second-generation British Renishaw high-speed scanners (CYCLON SERIES2) can be realized and contact laser probe complementary probe, laser scanner accuracy of 0.05mm, scanning probe contact accuracy of 0.02 mm. Another German company GOM ATOS portable scanners, Japan Roland's PIX-30, PIX-4 desktop scanner and the United Kingdom Taylor Hopson's TALYSCAN150 multi-sensor, respectively Three-dimensional scanner with high speed, low-cost and functional composite and so on. (2) CNC EDM Japan Sodick linear motor servo drive using the company's AQ325L, AQ550LLS-WEDM have driven fast response, transmission and high positioning accuracy, the advantages of small thermal deformation. Switzerland Chanmier company NCEDM with P-E3 adaptive control, PCE energy control and automatic programming expert systems. Others also used the powder mixed EDM machining technology, micro-finishing pulse power and fuzzy control (FC) technologies. (3) high-speed milling machine (HSM) Milling is an important means of cavity mold. The low-temperature high-speed milling with the workpiece, cutting force is small, smooth processing, processing quality, processing efficiency (for the general milling process 5 to 10 times) and can process hard materials (<60HRC) and many other advantages. Thus in the mold processing more and more attention. Ruishikelang company UCP710-type five-axis machining center, machine tool positioning accuracy up to 8μm, home-made closed-loop vector control spindle with a maximum speed 42000r/min. Italy RAMBAUDI's high-speed milling, the processing range of up to 2500mm × 5000mm × 1800mm, speed up 20500r/min, cutting feed speed of 20m/min. HSM generally used large, medium-sized mold, such as motor cover mold, die casting mold, large plastic surface machining, the surface precision up to 0.01mm. 3 The mold designing and manufacturing The mold is the manufacturing industry important craft foundation, in our country, the mold manufacture belongs to the special purpose equipment manufacturing industry. China although very already starts to make the mold and the use mold, but long-term has not formed the industry. Straight stabs 0 centuries 80's later periods, the Chinese mold industry only then drives into the development speedway. Recent years, not only the state-owned mold enterprise had the very big development, the three investments enterprise, the villages and towns (individual) the mold enterprise's development also rapid quietly. Although the Chinese mold industrial development rapid, but compares with the demand, obviously falls short of demand, its main gap concentrates precisely to, large-scale, is complex, the long life mold domain. As a result of in aspect and so on mold precision, life, manufacture cycle and productivity, China and the international average horizontal and the developed country still had a bigger disparity, therefore, needed massively to import the mold every year . The Chinese mold industry must continue to sharpen the productivity, from now on will have emphatically to the profession internal structure adjustment and the state-of-art enhancement. The structure adjustment aspect, mainly is the enterprise structure to the specialized adjustment, the product structure to center the upscale mold development, to the import and export structure improvement, center the upscale automobile cover mold forming analysis and the structure improvement, the multi-purpose compound mold and the compound processing and the laser technology in the mold design manufacture application, the high-speed cutting, the super finishing and polished the technology, the information direction develops . The recent years, the mold profession structure adjustment and the organizational reform step enlarges, mainly displayed in, large-scale, precise, was complex, the long life, center the upscale mold and the mold standard letter development speed is higher than the common mold product; The plastic mold and the compression casting mold proportion increases; Specialized mold factory quantity and its productivity increase; "The three investments" and the private enterprise develops rapidly; The joint stock system transformation step speeds up and so on. Distributes from the area looked, take Zhejiang Delta and Yangtze River delta as central southeast coastal area development quickly to mid-west area, south development quickly to north. At present develops quickest, the mold produces the most centralized province is Guangdong and Zhejiang, places such as Jiangsu, Shanghai, Anhui and Shandong also has a bigger development in recent years. Although our country mold total quantity had at present achieved the suitable scale, the mold level also has the very big enhancement, after but design manufacture horizontal overall rise and fall industry developed country and so on Yu De, America, date, France, Italy many. The current existence question and the disparity mainly display in following several aspects: (1) The total quantity falls short of demand Domestic mold assembling one rate only, about 70%. Low-grade mold, center upscale mold assembling oneself rate only has 50% about. (2) the enterprise organizational structure, the product structure, the technical structure and the import and export structure does not gather in our country mold production factory to be most is from the labor mold workshop which produces assembles oneself (branch factory), from produces assembles oneself the proportion to reach as high as about 60%, but the overseas mold ultra 70% is the commodity mold. The specialized mold factory mostly is "large and complete", "small and entire" organization form, but overseas mostly is "small but", "is specially small and fine". Domestic large-scale, precise, complex, the long life mold accounts for the total quantity proportion to be insufficient 30%, but overseas in 50% above 2004 years, ratio of the mold import and export is 3.7:1, the import and export balances the after net import volume to amount to 1.32 billion US dollars, is world mold net import quantity biggest country . (3) The mold product level greatly is lower than the international standard The production cycle actually is higher than the international water broad product level low mainly to display in the mold precision, cavity aspect and so on surface roughness, life and structure. (4) Develops the ability badly, economic efficiency unsatisfactory our country mold enterprise technical personnel proportion low The level is lower, also does not take the product development, and is frequent in the passive position in the market. Our country each mold staff average year creation output value approximately, ten thousand US dollars, overseas mold industry developed country mostly 15 to10, 000 US dollars, some reach as high as 25 to10, 000 US dollars, relative is our country quite part of molds enterprises also continues to use the workshop type management with it, truly realizes the enterprise which the modernized enterprise manages few To create the above disparity the reason to be very many, the mold long-term has not obtained the value besides the history in as the product which should have, as well as the most state-owned enterprises mechanism cannot adapt the market economy, but also has the following several reasons: . (1) Country to mold industry policy support dynamics also insufficiently Although the country already was clear about has promulgated the mold profession industrial policy, but necessary policy few, carried out dynamics to be weak. At present enjoyed the mold product increment duty enterprise nation 185; the majority enterprise still the tax burden is only overweight. The mold enterprise carries on the technological transformations introduction equipment to have to pay the considerable amount the tax money, affects the technology advancement, moreover privately operated enterprise loan extremely difficult. (2) Talented person serious insufficient, the scientific research development and the technical attack investment too urine mold profession is the technology, the fund, the work crowded industry, along with the time progress and the technical development, grasps the talented person which and skilled utilizes the new technology exceptionally short, the high-quality mold fitter and the enterprise management talent extremely is also anxious. Because the mold enterprise benefit unsatisfactory and takes insufficiently the scientific research development and the technical attack, the scientific research unit and the universities, colleges and institutes eye stares at is creating income, causes the mold profession invests too few in the scientific research development and the technical attack aspect, causes the mold technological development step doe not to be big, progresses does not be quick. (3) The craft equipment level is low, also is not good, the using factor is low. Recent years ,our country engine bed profession progressed quickly, has been able to provide the quite complete precision work equipment, but compared with the overseas equipment, still had a bigger disparity. Although the domestic many enterprises have introduced many overseas advanced equipment, but the overall equipment level low are very more than the overseas many enterprises. As a result of aspect the and so on system and fund reason, introduces the equipment not necessary, the equipment and the appendix not necessary phenomenon are extremely common, the equipment utilization rate low question cannot obtain the comparatively properly solution for a long time . (4) Specialization, standardization, commercialized degree low, the cooperation ability Because receives "large and complete" "small and entire" the influence since long ago, mold specialization level low, the specialized labor division is not careful, the commercialized degree is low. At present domestic every year produces mold, commodity mold minister 40% about, other for from produce uses for oneself. Between the molds enterprise cooperates impeded, completes the comparatively large-scale mold complete task with difficulty. Mold standardization level low, mold standard letter use cave rare is low also to the mold quality, the cost has a more tremendous influence, specially has very tremendous influence. (5) To the mold manufacture cycle) the mold material and the mold correlation technology fall The mold material performance, the quality and the variety question often can affect the mold quality, the life and the cost, the domestically produced molding tool steel and overseas imports the steel products to compare has a bigger disparity. Plastic, plate, equipment energy balance, also direct influence mold level enhancement. At present, our country economy still was at the high speed development phase, on the international economical globalization development tendency is day by day obvious, this has provided the good condition and the opportunity for the our country mold industry high speed development. On the one hand, the domestic mold market will continue high speed to develop, on the other hand, the mold manufacture also gradually will shift as well as the transnational group to our country carries on the mold purchase trend to our country extremely to be also obvious. Therefore, will take a broad view the future, international, the domestic mold market overall development tendency prospect will favor, estimated the Chinese mold will obtain the high speed development under the good market environment, our country not only can become the mold great nation, moreover certainly gradually will make the powerful nation to the mold the ranks to make great strides forward. "15" period, the Chinese mold industry level not only has the very big enhancement in the quantity and the archery target aspect, moreover the profession structure, the product level, the development innovation ability, enterprise's system and the mechanism as well as the technology advancement aspect also can obtain a bigger development . The mold technology has gathered the machinery, the electron, chemistry, optics, the material, the computer, the precise monitor and the information network and so on many disciplines, is a comprehensive nature multi-disciplinary systems engineering. The mold technology development tendency mainly is the mold product to larger-scale, precise, more complex and a more economical direction develops, the mold product technical content unceasingly enhances, the mold manufacture cycle unceasingly reduces, the mold production faces the information, is not having the chart, is fine, the automated direction develops, the mold enterprise to the technical integration, the equipment excellent, is producing approves the brand, the management information, the management internationalization direction develops. Mold profession in "十15" period needs to solve the key essential technology should be the mold information, the digitized technology and precise, ultra fine, high speed, the highly effective manufacture technology aspect breakthrough Along with the national economy total quantity and the industry product technology unceasing development, all the various trades and occupations to the mold demand quantity more and more big, the specification more and more is also high. Although mold type many, but its development should be with emphasis both can meet the massive needs, and has the comparatively high-tech content, specially at present domestic still could not be self-sufficient, needs the massive imports the mold and can represent the development direction large-scale, precise, is complex, the long life mold. Standard letter type, quantity, level and the production of the mold have significant influence to the entire mold profession development. Therefore, some important mold standard letters also must prioritize, moreover its development speed should quickly to the mold development speed, like this be able unceasingly to raise our country mold standardization level, thus improves the mold quality, reduces the mold production cycle, reduces the cost. Because our country mold product holds the bigger price superiority in the international market, therefore regarding the exportation prospect good mold product also should take key develops. According to the above required quantity big, the technical content is high, represents the development direction, the export prospect good principle choice prioritize product, moreover chooses the product to have at present to have the certain technology base, belongs has the condition, has the product which the possibility develops . 模具的發(fā)展史 作者：丹尼爾.弗倫克勒 單位：紐約巴塞爾大學(xué) 1.模具CAD/CAE/CAM正向集成化、三維化、智能化和網(wǎng)絡(luò)化方向發(fā)展 （1）模具軟件功能集成化 模具軟件功能的集成化要求軟件的功能模塊比較齊全，同時各功能模塊采用同一數(shù)據(jù)模型，以實現(xiàn)信息的綜合管理與共享，從而支持模具設(shè)計、制造、裝配、檢驗、測試及生產(chǎn)管理的全過程，達到實現(xiàn)最佳效益的目的。如英國Delcam公司的系列化軟件就包括了曲面/實體幾何造型、復(fù)雜形體工程制圖、工業(yè)設(shè)計高級渲染、塑料模設(shè)計專家系統(tǒng)、復(fù)雜形體CAM、藝術(shù)造型及雕刻自動編程系統(tǒng)、逆向工程系統(tǒng)及復(fù)雜形體在線測量系統(tǒng)等。集成化程度較高的軟件還包括：Pro/ENGINEER、UG和CATIA等。國內(nèi)有上海交通大學(xué)金屬塑性成型有限元分析系統(tǒng)和沖裁模CAD/CAM系統(tǒng)；北京北航海爾軟件有限公司的CAXA系列軟件；吉林金網(wǎng)格模具工程研究中心的沖壓模CAD/CAE/CAM系統(tǒng)等。 （2）模具設(shè)計、分析及制造的三維化 傳統(tǒng)的二維模具結(jié)構(gòu)設(shè)計已越來越不適應(yīng)現(xiàn)代化生產(chǎn)和集成化技術(shù)要求。模具設(shè)計、分析、制造的三維化、無紙化要求新一代模具軟件以立體的、直觀的感覺來設(shè)計模具，所采用的三維數(shù)字化模型能方便地用于
