家用五孔插座下壳盖注塑模具设计.docx

摘要
塑料产品在如今的生活中受到越来越广泛的应用,和人民的生活息息相关。塑件又是通过塑料模具生产的,所以塑料模具的设计也越来越重要。模具的结构和形状尺寸的设计是整个设计的重中之重,结构和形状尺寸的设计不合理,将无法做出适合的塑件。如果结构和形状尺寸的设计太繁琐,将会大大的浪费材料,增加成本,无法达到经济性条件。当然,一个真正实用的塑件的产生,其他的因素也是必不可少的,例如:塑件产品本身材质的选择、成型设备的选择、模具材料的选择等等。
本设计主要介绍了一套完整的塑料模具设计所需要的基本因素,分析了成型设备的特性,并对模具的基本结构进行了计算分析,涵盖了从塑料开始融化直到成为塑件为止所需要的全部流程。然后通过AutoCAD绘制出模具的二维装配图,用Pro/E绘制出模具的三维实物图,在此基础上展现模具的结构以及各个结构之间的配合。

Abstract: In today's life, Plastic products is used more and more widely, and it is closely linked with people's life. Production is get through the plastic mould, so the design of the plastic mold is ing more and more important. The design of the mould about structure and shape dimension is the key of the whole design, the design of the structure and shape dimension is unreasonable, will not be able to make suitable for plastic parts. If the design of the structure and shape dimension is too trival, it will be a greatly waste in materials, and increase the cost of the mould, so it is not economic. Of course, a real and practical production of plastic parts, other factors also is indispensable, for example: plastic product itself material choice, the choice of molding equipment, selection of die material and so on.
This design mainly introduced the basic factors of plete set of plastic mold, analyse the characteristics of the molding equipment, and make a calculation and analysis about basic structure of the mould, ranging all required processes from plastic melting until e plastic parts. Then draw 2d assembly drawing of the mould by the AutoCAD, using Pro/E to draw the three-dimensional physical figure of mould, on the basis of the present show the mould structure and cooperation between different structure.
Keywords: Plastic; mould design; injection molding machine; mould structure; AutoCAD; Pro/E
