深圓筒形沖壓模設計摘 要系統(tǒng)介紹了工件的成形工藝及模具成型結(jié)構對塑件質(zhì)量的影響分析，模具成型部分和總裝結(jié)構的設計。介紹了圓筒拉深模具設計時要注意的要點，并較多的考慮了模具結(jié)構的調(diào)整性、易更換性及模具成本。從控制制件尺寸精度出發(fā)，對圓筒拉深模具的各主要尺寸進行了理論計算，以確定各工作零件的尺寸，從模具設計到零部件的加工工藝以及裝配工藝等進行詳細的闡述，并應用CAD進行各重要零件的設計。關鍵詞：工藝分析；工件成型；模具結(jié)構。The design of stretching die about cylinderAbstractThe molding process of work piece, the effect analysis to work piece quality caused by molding structure, partial and general design of mold moulding introduced respectively. The critical points of mold for work 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 brrel 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; work piece moulding; molding structure.
