Abstract
The key link of changing plastic raw materials into products is the plastics molding process. Plastic processing and mold technology is an evolving integrated subject. Not only with the improving synthesis technology of the polymeric materials, the innovations of the molding equipments, the maturity of processing technology to make progress , but also with the infiltration of computer technology, numerical simulation technology and so on in the field of plastics molding process to access development. The design through the study of mold and the factory-site study, to analysis the mold structure, meanwhile,drawing on the experiences in the design of programs of scholars from home and abroad to determine the program. Major study is the materials selection of the plastic molds, the application of injection machine, the layout of cavity and the design of regional type, the design of gating system, the design of cooling system, the design of prototyping parts, die-selection, mold design-oriented institutions, the design of ejection mechanism, the check of injection machine, then we can design the injection mold of insulation cup.

1 绪论
模具是工业生产中使用极为广泛的基础工艺装备。在汽车、机电、仪表、电器、电子、通信、家电和轻工等行业中,60%~80%的零件都依靠模具成形,并且随着近年来这些行业的迅速发展,对模具的要求越来越迫切,精度要求越来越高,结构要求也越来越复杂。用模具生产制件所表现出来的高精度、高复杂性、高一致性、高生产效率和低消耗,是其他加工制造方法不能比拟的。模具生产技术的高低,已成为衡量一个国家产品制造水平的重要标志。
模具的类型很多,按照成型件的材料不同,可分为冲压模具、塑料模具、锻造模具、压铸模具、橡胶模具、粉末冶金模具、玻璃模具和陶瓷模具等,其中应用最广泛的是冲压模具和塑料模具,其中应用最广泛的是冲压模具和塑料模具。
塑料成型加工技术的发展仍在继续,其近期发展趋势如下:
(1)由单一性技术向组合性技术发展,如注射——拉伸——吹塑成型技术和挤出——模压——热成型技术等;
(2)有常规条件下的成型技术向特殊条件下的成型技术发展,如超高压和高真空条件下的塑料成型加工技术;
(3)由基本上不改变原有性能的保质成型加工技术向赋予塑料新型性能的变质成型加工技术发展,如双轴拉伸薄膜成型、发泡成型和借助电子束和化学交联机使热固性塑料在成型过程中进行交联挤出等;
