文档介绍：MP3电池充电器插座的塑料注射模具的设计
摘要
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,例如是采取整体式还是镶拼式,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图。

The Design of Plastic Injection Mold for MP3 Battery Charger Socket
Abstract
This design is mainly the feasibility analysis of plastic parts of the shape, size and accuracy requirements for injection molding process. Molding of plastic parts including plastic parts wall thickness, inclination and fillet and whether core-pulling mechanism. Through the above analysis to determine the mold parting surface, cavity number, gate the form, place the size; the most important is to determine the core and cavity structure, for example, is to take the whole the type of type still, and their fixed position and tight way. In addition, the force of the mold, demoulding mechanism design, mold design guide mechanism, cooling system design, the die assembly drawing and the main parts of the die drawing.
Key Words: Injection molding;parting surface;moulded parts;core pulling mechanism
