摘要
本文详细介绍了注射模具分型面成型零部件、分型面、浇注系统、温度调节系统和顶出系统等模具主要的设计过程,并对模具强度要求做了说明。设计中对注射机的相关重要参数进行验证,包括模具闭合厚度、模具安装尺寸、模具开模行程、注射机的锁模力等。校核合格后,进行成型零件加工工艺过程的制定,既要保证塑件的质量,又要兼顾经济性。
通过本次设计,可以对注射模具有一个初步完整的认识,注意到设计中的某些细节问题,如制件的结构、成型零部件的尺寸计算,了解模具结构及工作原理;最后在设计过程中运用Pro/E、Auto CAD软件进行注塑模结构设计与计算并绘制出模具总装图以及部分非标准图形。从而得出完整的理论设计结果,为今后工程设计打下了基础。

Abstract
This paper design introduced the injection takes shape the basic principle,to cast the product to propose the basic principle of design;Introducedin detail Divides the profile、the cole flow channel injection evil spirit mold pours the system,the temperature control system and goes against the system the design process,and has given the explaination to the mold intendity shaped parts,reasonable drawing mechanism and so design should be certification,Primarily related to the injection machine of important parameters fpr the certification including die close thickness sizes,the name distance,injection machine of the die drae force and so Qualifide in check,the molding parts machining process design must ensure that the quality of Supervision taking into account the economy.
Final assembiy is part of the mold,which including the design of assembly steps,clear proceeding requirde attention.
Through this design,may to cast the mold to have a preliminary understanding,notes in the design certain detail question,understands the mold structure and the principle od work and some non-standard drawings with Pro/E and AutoCAD, to obtain the final theoretical design. The design lays a foundation for future design.
