文档介绍：摘要
如今,模具设计与制造是一种非常有前景的行业。中国模具企业一般都是中小型企业,模具加工技术相对发达国家还有很大的差距。学习模具专业的大学生,不仅仅要学习模具的先进技术,也要学习先进的模具管理技术。中国模具现在还极度缺乏高素质的人才,正是这个因素阻碍了中国模具质量的提升。
模具是制造业的重要工艺基础,。根据塑件的结构,选用了两侧带有斜顶机构的两板模,运用机动完成塑件的顶出,采用侧浇口完成进料。在整个设计过程中,查阅了大量的参考资料,深入分析设计内容,包括运用Proe软件对产品进行壁厚和拔模斜度的分析。塑件成型工艺性分析;拟定模具结构形式。
注射机型号的确定;浇注系统形式和浇口的设计;成型零件的结构设计和计算;模架的确定和标准件的选用;合模导向机构的设计;脱模推出机构的设计;斜顶机构的设计;冷却系统的设计。
通过该外壳塑料模具的设计使自己对塑料模具的设计流程有了更深一层次的认识,进一步体会到如 Proe, Moldflow,emx,Autocad等软件在模具各阶段设计过程中所扮演的角色和带来的便利,也深刻的体会到强大的CAD软件在缩短模具设计、生产周期、降低成本方面起了不可或缺的作用。虽然CAD设计软件拥有强大的分析处理功能,但也要有扎实的理论基础和实际经验才能将其发挥到极至。

ABSTRACT
Nowdays , Mold design and manufacture is ing a promising industry. The truth is there are still a lot of small factories in China. Compared with the developed country, the technology of mold design and manufacture is still far behind the developed country. As a graduate whose major is Mold design and Manufacture, I think we not only need to learn some advanced technology, we also need to learn some advanced experience. In China, a lot of high quality workers are needed. This is the main reason why mold technology is not highly promoted in China.
The mold is the manufacturing industry important craft foundation, in our country, the mold manufacture belongs to the special purpose equipment manufacturing industry. According to the structure of the plastical piece chose to use the two plates mold with two sidecores. make use of inclined lead pletion side core-pulling of the plasticalpiece and adopt side pletion injection .Checked a great deal of reference in the whole design process, thorough analysis the design contents, include usage Proe software to carry on wallthinckness and draft analysis for the product。The craft analysis of mold;Draft the mold structure form.
The assurance of injection machine model ;design of injection system and gate;Model structure design and calculation of mold parts; The assurance of mold base with standard piece of choose to u
