手機(jī)后蓋的注塑模具設(shè)計(jì)【一模兩腔側(cè)向抽芯】

摘  要

我國(guó)塑料模具工業(yè)從起步到現(xiàn)在，經(jīng)歷了半個(gè)世紀(jì)，有了很大發(fā)展，模具水平有了較大的提高。由于模具生產(chǎn)產(chǎn)品具有精度高，復(fù)雜性高，一致性好，生產(chǎn)效率高消耗低等優(yōu)點(diǎn)。所以現(xiàn)代工業(yè)中將會(huì)起到更大的作用，得到更多的應(yīng)用。我的塑料發(fā)展至今，已能生產(chǎn)精度高達(dá)2微米的精密，多工位級(jí)進(jìn)模，工位數(shù)最多已達(dá)160個(gè)，壽命1~2億次。

模具時(shí)現(xiàn)代工業(yè)發(fā)展的基礎(chǔ)，許多產(chǎn)業(yè)的發(fā)展都離不開模具行業(yè)的支持。用模具生產(chǎn)制造所表現(xiàn)出來的的高精度，高復(fù)雜程度，高一致性，高生產(chǎn)率和低消耗，是其他加工制造方法所不能比擬的。在模具工業(yè)的總產(chǎn)值中塑料模具約占33%。不同的塑料成型方法使得模具原理和結(jié)構(gòu)不通。按照成型方法的不通，塑料模具分為：注塑模具，壓塑模具，吹塑模具等。注塑模具主要用于熱塑性塑料制品的成型中占有很大比重?，F(xiàn)代工業(yè)中，消費(fèi)品外殼的色彩，手感，和精度，厚度等提出了新要求。塑料外殼設(shè)計(jì)成為重要的一環(huán)。設(shè)計(jì)合理的注塑模具將得到越來越多的應(yīng)用。

現(xiàn)代注塑模具的設(shè)計(jì)方法目前為了應(yīng)付當(dāng)前多樣化的要求，縮短產(chǎn)品只在周期以缺德最佳的競(jìng)爭(zhēng)優(yōu)勢(shì)，模具設(shè)計(jì)中都引用了CAD/CAE計(jì)算機(jī)一體化制造技術(shù)，以提高產(chǎn)品質(zhì)量，降低成本，增加競(jìng)爭(zhēng)力，一般而言，一件完整理想的工業(yè)產(chǎn)品，其制造流程為現(xiàn)有原創(chuàng)型的概念設(shè)計(jì)出原件，配合計(jì)算機(jī)輔助工程分析技術(shù)，再依據(jù)分析結(jié)果修改測(cè)試，最后再依據(jù)設(shè)計(jì)圖經(jīng)由計(jì)算機(jī)輔助制造，進(jìn)行產(chǎn)品自動(dòng)化生產(chǎn)在模具設(shè)計(jì)生產(chǎn)，以上整個(gè)過程均在計(jì)算機(jī)上進(jìn)行。

在模具設(shè)計(jì)生產(chǎn)過程中，應(yīng)用Pro/ENGINEER軟件進(jìn)行模具結(jié)構(gòu)設(shè)計(jì)-模具型腔-型芯二維設(shè)計(jì)-工藝準(zhǔn)備-模具型腔，型芯設(shè)計(jì)三維造型等。

隨著計(jì)算機(jī)技術(shù)和網(wǎng)絡(luò)技術(shù)取得了突破性的成就，模具設(shè)計(jì)越來越多地使用CAD/CAM技術(shù)。在產(chǎn)品生產(chǎn)之前，使用這些新技術(shù)來進(jìn)行模具的設(shè)計(jì)和改善，是現(xiàn)代設(shè)計(jì)必然趨勢(shì)在現(xiàn)實(shí)生活里，手機(jī)已經(jīng)成為人們的一個(gè)生活必須品，現(xiàn)代的手機(jī)已經(jīng)不再僅僅是一個(gè)工具同時(shí)一時(shí)裝飾品，所以做出的不管是手機(jī)機(jī)身還是手機(jī)殼都需要美觀大方，因此加工工藝就顯得非常重要。所以在對(duì)手機(jī)殼的模具設(shè)計(jì)時(shí)不僅要考慮成型，還需要考慮成型后的美觀。因此在模具的設(shè)計(jì)過程中多方兼顧。

Abstract

Plastic mold industry in China from the beginning to now, has experienced half a century, has made great development, mould level has greatly improved. Because the mold production product has high accuracy, high complexity, good consistency and high efficiency low consumption etc. So modern industry will play a greater role, get more applications. Precision plastic development up to now, I have been able to produce as much as 2 micron precision, multi-station progressive die, has reached the maximum number of stations in 160, life 1 ~ 200 million times.

Mould the basis for the development of modern industry, many industry's development cannot leave the mould industry support. With mold manufacturing of high precision, high complexity, high consistency, high productivity and low consumption, is can't be matched by other methods of processing and manufacturing. In the mold industry plastic mould accounted for about 33% of the total output. Different methods of plastic molding makes mold principle and structure. According to the forming method of impassability, plastic mold is divided into: injection mold, compression mold, blow molding mould, etc. In the injection mold is mainly used for thermoplastic plastics molding occupies a large proportion. In modern manufacturing, consumer goods shell color, feel, and precision, thickness, etc. Put forward new requirements. Plastic shell design become important one annulus. Reasonable design of injection mould will be applied more and more.

Modern design method of injection mould at present in order to cope with the current diversified requirements, shorten the product by the wicked the best competitive advantage, only in the cycle of mould design reference the CAD/CAE technology of computer integrated manufacturing, in order to improve the product quality, reduce cost, increase the competitiveness, in general, a complete ideal industrial products, the concept of the manufacturing process for existing original type original design, with computer aided engineering analysis techniques, according to the results of analysis, modifying test again, and then on the basis of design through computer aided manufacturing, automated production in the mold design production, more than the whole process are conducted on the computer.

In the mold design and production process, the application of Pro/ENGINEER software to design the mould structure - the mold - core of two-dimensional design process to prepare - mold cavity, core design three dimensional modeling, etc.

Along with the computer technology and network technology has achieved breakthrough and mold design are increasingly using CAD/CAM technology. Before production, the use of these new technologies for the design of the mould and improvement, is an inevitable trend in the modern design in real life, mobile phones have become a people living necessities, modern mobile phone is no longer just a tool for decoration at the same time, so the mobile body or following needs to be beautiful and easy, so the processing technology is very important. So when opponents casing mold design should not only consider the forming, also need to consider after molding. Therefore, in the mold design process to two or morethings.

Key words：Cell phones, mold design, injection mould, inclined guide pillar, side core-pulling
