φ60x100衬筒注塑模具设计 毕业论文.doc

摘 要 近几年好多国家都在发展机械行业，与机械相关的各个行业都越来越重视/CAM技术，如今/CAM技术已发展成为一项比较成熟的共性技术，我国家电工业的高速发展对模具工业，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，其中发展重点为工程塑料模具。同时还因为塑料制品及模具的3设计与成型过程中3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对“”外形进行3造型，同时也设计了其塑料注塑模的3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；此外还利用绘制了模具装配图以及各种成型零件图。 /CAM；塑料；模具； Abstract A 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 2004, 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 according to the design of the mould size choose to install the corresponding mold frame, the resulting intuitive structure design; In addition to use CAD draw the mold assembly drawing as well as a variety of molding part drawing.
