1、台灯罩模具设计及其型腔仿真加工摘要：本课题设计是对台灯罩模具设计和型腔仿真加工。设计过程中采用Pro/EWildfire4.0进行三维造型、分型面设计和模流分析，用CAD进行零件图和装配图的绘制，用Mastercam9.1进行模具型腔的仿真加工。根据制品的体积、质量和要求选定注塑机型号，再确定模具型腔为一模二腔;考虑模具外观要求等诸多因素，选取分型面在塑件的底面；为使塑件能够快速均匀的冷却，冷却流道布置为环绕式；浇口采用潜伏式浇口，使两个型腔同时得到均匀的充填和成型；由于制品需要侧抽芯，经过验证，抽芯机构采用

2、最常用的斜导柱分型与抽芯机构；顶出机构是制品的脱模装置，依据塑件结构采用8根顶杆;由于塑件是薄壁结构可能岀现注塑不完整，通过模流分析验证注塑流体可以充满型腔，符合设计要求。分析型腔的加工工艺，在Mastercam9.1中完成刀具路径设定，确定数控加工代码，通过仿真加工确定是否满足加工要求。通过使用模具设计应用软件，使模具设计效率大大提高，符合设计要求。关键词：模具设计仿真加工注塑模具TheDesignandSimulationProcessingofReadingLampMoldAbstract:Thissu
