摘要
近年来,我国的模具发展迅速,尤其是塑料模具提出了越来越高的要求,最近几年,塑料模具在整个模具行业所占的比例上升到30%左右,相信在未来的时间里,中国塑料模具工业还将保持年均增长速度达到10%以上较高速度的发展,国内塑料模具市场以注塑模具需求量最大。将来注射模具发展的方向向更精密、更高效、复合和多功能、更大型、更精密、更复杂、更绿色及更经济的方向发展,模具产品的技术含量将不断提高,模具制造周期将不断缩短。
注射成型是塑料成型的一种重要的方法,它主要适用于热塑料的成型,可以一次成型简单或复杂的精密塑件。本课题是将水杯作为设计模型,将注塑模具的相关知识作为依据,阐述塑料注射模具的设计过程。介绍塑件结构形状,塑件的材料选择,及塑件的结构工艺性,注射机成型的设备组成分类及型号规格。
本文详细介绍了水杯注塑模具的设计,从产品的结构工艺性分析,具体模具结构出发,选择模具型腔的分型面,型腔的数量,以及对模具的浇注系统的设计,模具成型零件的分析计算,合模导向机构的设计,推出机构,使用EMX(模架设计专家)进行模架的设计,最后对三维造型使用Pro/Engineer形同转出dwg文件进行出图。

Abstract
. In recent years, China's rapid development of the mold, especially the plastic mold of the increasingly high demand, in recent years, the plastic mold in the mold industry the proportion of up to 30% jobs, I believe in ing years, China plastic mold industry will maintain an average annual growth rate of more than 10% high speed development, the domestic market to plastic mold injection mold greatest demand. The future development direction of injection mold to more sophisticated, more efficient, complex and multi-purpose, larger, more sophisticated, plex, more green and more economic development, mold the technical content of the product will continue to improve, the manufacturing cycle of the die will shorten ceaselessly.
Plastic molding injection molding is an important method, which is mainly applied to the thermal plastic molding, molding can be a simple plex precision plastic parts. This topic is the cup as a design model, the injection mold related knowledge as the basis, elaborates the design process of plastic injection mold. Introduction to the structure of plastic parts plastic parts shape, material selection, and the structure process of plastic products, injection molding machine position classification and specifications.
This paper introduces in detail the cup injection mold design, from product structure manufacturability analysis, the specific struct
