肥皂盒注塑模具设计与制造
摘 要: 近几年国家振兴机械行业，与机械相关的各个行业都越来越重视CAD/CAM技术，不仅是因为CAD/CAM技术已发展成为-项比较成熟的共性技术，同时还因为塑料制品及模具的3D设计与成型过程中3D分析正在塑料模具工业中发挥越来越重要的作用。在本次毕业设计中，通过CAD绘制了模具装配图以及各种成型零件图。这是第-次利用绘图软件对整套模具进行设计，对所学知识进行了全面巩固，意义重大！

Soap box of injection mold design and manufacturing
Abstract: Over the past few years the country vitalizes machinery industry， each industry that related with mechanics is all paying more and more attention to the CAD/CAM technology. That is not only because CAD/CAM technology has already been developed into one ripe generality technology， but also because 3D design of Plastics piece make and mould and 3D analysis of molding process plays a more and more important role in plastics mould industry. In the graduation project， has drawn up the mold assembly drawing as well as each kind of Molding Parts drawing using CAD . This is that the first time makes use of the software drawing to carry out design on package mould ， have carried out all-round consolidation on what be learned knowledge，The significance is significant！
