摘要
該設(shè)計(jì)較系統(tǒng)的介紹了簡(jiǎn)單注塑模具的設(shè)計(jì)過(guò)程。同時(shí)對(duì)塑件的成形工藝及模具成型結(jié)構(gòu)對(duì)塑件質(zhì)量的影響進(jìn)行了分析。在設(shè)計(jì)過(guò)程中，首先對(duì)塑件進(jìn)行工藝分析，了解塑件的材料、形狀、尺寸及精度要求，參考工藝的可行性，選擇滿足要求的工藝方案。然后我按照設(shè)計(jì)要求對(duì)組成注塑模具的成型零部件、澆注系統(tǒng)、導(dǎo)向機(jī)構(gòu)、脫模結(jié)構(gòu)、側(cè)向分型與抽芯機(jī)構(gòu)、加熱與冷卻系統(tǒng)、排氣系統(tǒng)和其它零部件進(jìn)行設(shè)計(jì)。在模具設(shè)計(jì)過(guò)程中較多的考慮了模具結(jié)構(gòu)的調(diào)整性、易更換性及模具成本。從控制制件尺寸精度出發(fā)，對(duì)計(jì)算機(jī)按鍵注塑模的各主要尺寸進(jìn)行了理論計(jì)算，以確定各工作零件的尺寸。模具零件設(shè)計(jì)完畢后，對(duì)重要的工作結(jié)構(gòu)和零件進(jìn)行了校核。校核結(jié)束后對(duì)模具安裝并調(diào)試。從模具設(shè)計(jì)到零部件的加工工藝以及裝配工藝等進(jìn)行詳細(xì)的闡述，并應(yīng)用CAD進(jìn)行各零件的設(shè)計(jì)。

Abstract
This design systematic introduction has simply cast the mold the design process. Meanwhile to modelled the formed craft and the mold takes shape the structure to model a quality the influence to carry on the analysis. In the design process, first to models to carry on the craft analysis, understood models a material, the shape, the size and the precision request, the reference craft feasibility, the craft plan which the choice answers the purpose. Then I to compose according to the design request cast the mold to take shape the spare part, pour the system, the guidance organization, the drawing of patterns structure, lateral dividing with pull out the core organization, heat up with the cooling system, the exchaust gas system and other spare parts carry on the design. In mold design process many considerations mold structure adjustment, easy replacement and mold cost. Embarks from the control workpiece size precision, molded each main dimension to the computer pressed key note to carry on the theoretical calculation, by determined each work components the size. After the mold components design finished, has carried on the examination to the important work structure and the components. After the examination had finished to mold installment and debugging. Designs from the mold to the spare part processing craft as well as the assembly craft and so on carries on the detailed elaboration, and carries on various components using CAD the design.
