文档介绍：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CAD/CAM技术,如今CAD/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,2004年,塑料模具在整个模具行业中所占比例已上升到30%左右,据有关专家预测,在未来几年中,中国塑料模具工业还将持续保持年均增长速度达到10%以上的较高速度的发展。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“吹风机外壳”外形进行3D造型,同时也设计了其塑料外壳注塑模的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。这是本人第一次利用UG软件对一整套模具进行设计,使大学四年所学的知识得到运用,并加以指导老师的指导,受益匪浅!

Abstract
Years, a lot of countries in the development of the machinery industry, mechanical industry more and more attention to the CAD / CAM technology, today's CAD / CAM technology has developed into a more mon technology, the rapid development of China's household electrical appliance industry moldindustry, especially the plastic mold ever-increasing demands, 2004, plastic mold in the mold industry proportion has risen to about 30% in ing years, experts predict China plastic mold industrywill continue to maintain an average annual growth rate of more than 10% higher speed. Domestic plastic mold market to the demand for plastic injection mold, the focus of development for engineering plastics mold. Also because the plastic products and mold 3D design and molding process 3D analysis play an increasingly important role in the plastic mold industry. In this graduation project, through the use of dimensional solid modeling high-end software UG "hair dryer shell" shape 3D modeling, at the same time also designed the its plastic shell injection mold 3D model; also based on the design of the mold size choose to install the corresponding mold, the resulting intuitive structure design; addition, the use of CAD drawing mold assembly drawing and a variety of molded parts diagram. This is the first time I use the the UG software on a set of mold design, four years in college to learn to use the knowledge and to the guidance of the instructor and benefit!
