長接頭注塑模設計
摘要
介紹了塑件的成形工藝及模具成型結構對塑件質量的影響分析，澆注系統(tǒng)的設計，模具成型部分和總裝結構的設計。介紹了長接頭注塑模具設計時要注意的要點，并較多的考慮了模具結構的調整性、易更換性及模具成本。從控制制件尺寸精度出發(fā)，對長接頭注塑模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；塑件成型；澆注系統(tǒng)；模具結構。
Injection Mold for long Junction
Abstract
The molding process of plastic parts, the effect analysis to plastic parts quality caused by mold molding structure, as well as the casting system design, partial and general design of 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 theoretical calculation 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.
