摘   要

本次毕业设计的题目是：5号电池充电器外壳的塑件注射模。本次设计主要是通过对塑件的形状、尺寸及其精度的要求来进行注射成型工艺的可行性分析。塑件的成型工艺性主要包括塑件的壁厚，斜度和圆角以及是否有抽芯机构。通过以上的分析来确定模具分型面、型腔数目、浇口形式、位置大小；其中最重要的是确定型芯和型腔的结构，例如是采用整体式还是镶拼式，以及它们的定位和固紧方式。此外还分析了模具受力，脱模机构的设计，合模导向机构的设计，冷却系统的设计等。最后绘制完整的模具装配总图和主要的模具零件土及编制成型零部件的制造加工工艺过程卡片。 [资料来源：http://think58.com]

关键词：分型面、浇口、型腔，型芯，镶块，脱摸力。

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.
