摘要：系統(tǒng)介紹了塑件的成形工藝及模具成型結(jié)構(gòu)對塑件質(zhì)量的影響分析，澆注系統(tǒng)的設(shè)計，模具成型部分和總裝結(jié)構(gòu)的設(shè)計。介紹了端蓋注塑模具設(shè)計時要注意的要點，并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)，對端蓋注塑模的各主要尺寸進(jìn)行了理論計算，以確定各工作零件的尺寸，從模具設(shè)計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)行各重要零件的設(shè)計。

Abstract ：The molding process of plastic parts, the effect analysis to plastic parts quality caused by molding structure, as well as the casting system design, partial and general design of mold moulding introduced respectively. The critical points of mold for plastic design are introduced, and the adjustable character of molding structure、exchange character as well as the molding costs are all considered farther. Starting from controlling dimensional accuracy, the carry the cover to the main dimensions of injection molding are carried out so as to determine the size of different parts, the molding design and the process of parts as well as assembling process and etc of injection molding are stated in details.
Key words: process analysis; plastic parts moulding; casting system; molding structure.
