摘 要
本次畢業設計的題目是：5號電池充電器外殼的塑件注射模。本次設計主要是通過對塑件的形狀、尺寸及其精度的要求來進行注射成型工藝的可行性分析。塑件的成型工藝性主要包括塑件的壁厚，斜度和圓角以及是否有抽芯機構。通過以上的分析來確定模具分型面、型腔數目、澆口形式、位置大小；其中最重要的是確定型芯和型腔的結構，例如是采用整體式還是鑲拼式，以及它們的定位和固緊方式。此外還分析了模具受力，脫模機構的設計，合模導向機構的設計，冷卻系統的設計等。最后繪制完整的模具裝配總圖和主要的模具零件土及編制成型零部件的制造加工工藝過程卡片。
關鍵詞：分型面、澆口、型腔，型芯，鑲塊，脫摸力。
Abstract
This graduate that design is:The piece that shout the on board cap injects the mold.This design primarily passeses to piece viability assessment for request for of shape, size and its accuracy coming proceeding injecting type craft.the piece the wall for of type craft primarily including the piece is thick, slope and circle angle and whether to have core-pulling or not mechanism.Pass the above analysis to come the certain molding tool cent the type the surface, type the number, gate the form, place the size;The among them and most important is a certain type core and the construction of the type , for example adopt the whole the type of type still , and their fixed position and tight way of .In addition and still analyzed the molding tool to suffer force, mold that design that the design of the pattern draw mechanism, match the design etc. to lead to the mechanism, cooling system.Finally draw the production that complete molding tool assemble the general drawing sum the soil and establishment of prinipal molding tool parts type zero the parts process the craft process the card.
Key words: parting line,the gate, slide block, heel block, core-pulling, core-pulling distance, gate.
