摘 要近几年好多国家都在进展机械行业，与机械相关的各个行业都越来越重视 CAD/CAM 技术，如今 CAD/CAM 技术已进展成为一项比较成熟的共性技术，我国家电工业的高速进展对模具工业，尤其是塑料模具提出了越来越高的要求,国内塑料模具市场以注塑模具需求量最大，其中进展重点为工程塑料模具。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，通过运用三维实体造型高端软件 UG 对“衬筒”外形进行 3D 造型，同时也设计了其塑料注塑模的 3D 模型；还根据所设计的模具尺寸选择安装了相应的模架，最终生成了直观的结构设计图；此外还利用 CAD 绘制了模具装配图以及各种成型零件图。关键词：CAD/CAM；塑料；模具；UGAbstractA lot of countries in the development of machinery industry in recent years, every industry pay more and more attention to related to mechanical CAD/CAM technology, CAD/CAM technology has now developed into a relatively mature technology, with the rapid development of our country home aPEliance industry of mold industry, puts forward higher and higher requirements, especially plastic mould, in 2025, as a proportion of the plastic mold in the mold industry has risen to 30%, according to experts predict that in the next few years, China plastic mould industry will continue to maintain an annual growth rate of more than 10% of the high speed of development. Domestic demand in injection mold plastic mold market is the largest, the key for engineering plastic mold development. Also because of the plastic products and mould 3 d design and molding process of 3 d analysis is the plastic mold industry plays a more and more important role. In this graduation design, the high-end software UG three-dimensional entity model is used to shape of "t type mounting bracket" 3 d modeling, and design the 3 d model of the plastic injection mold; Also ...
