塑料齿轮模具设计及其型腔仿真加工
摘 要：本课题来源于盐城羽佳塑业，任务是塑料齿轮模具设计及其型腔仿真加工.注射成型是塑料成型的一种重要方法，它主要适用于热塑性塑料的成型，可以一次成型形状复杂的精密塑件。本课题就是将双联齿轮作为设计模型，将注射模具的相关知识作为依据，阐述塑料注射模具的设计过程。
本设计对双联齿轮进行的注塑模设计，利用proe软件对塑件进行了实体造型，对塑件结构进行了工艺分析。明确了设计思路，确定了注射成型工艺过程并对各个具体部分进行了详细的计算和校核。如此设计出的结构可确保模具工作运用可靠，保证了与其他部件的配合。 最后用mastercam仿真加工型腔。
本课题通过对双联齿轮杯的注射模具设计，巩固和深化了所学知识，取得了比较满意的效果，达到了预期的设计意图。

The design of gear plastic injection mold and cavity simulation processing
Abstract: The subjects come from the Yujia Plastic Corporation. Task is what the design of gear plastic injection mold and cavity simulation processing. Plastic injection molding molding is an important method, which is primarily applicable to thermoplastic plastic molding, Molding can be a complex shape of precision plastic parts. To study the topic ,we make double-gear the design model, make the injection mold-related knowledge the basis for elaborate plastic injection mold design process.
In the designment we design double-gear with the injection mold design, using software proe to plastic parts to solid modeling, and making technics analysis to the structure of Plastic Parts for the process.We definite the design,and identify the injection molding process as well as some specific details of the calculation and verification.The structure of such a design can be used to ensure reliable Die work ,to ensure cooperation with the other parts of the tie. Finally，simulation processing cavity with mastercam .
we have consolidated and deepened the learning, gain a satisfied result, achieve the desired design intent through the process of double-gear mold design.
