文档介绍：模具设计及三维造型设计
摘要:塑料制品已在工业,农业,国防和日常生活中的方方面面得到了广泛应用。特别是在电子行业中则更为突出。电子产品的外壳大部分都是塑料制品,产品性能的提高就要求有高素质的塑料模具以及塑料性能,成型工艺和制品的设计。
本课题是一个关于电子产品的盒盖制件的模具设计。研究的重点是模具工艺设计和结构设计的过程,包括型腔数的确定、型腔和型芯尺寸的计算、浇注系统的设计、浇口套的选择、分型面与排气系统的设计、合模导向和脱模结构的设计、Pro/Engineer的介绍、工艺方案的制定和成型件的工艺计算、主要零部件的结构分析计算及其标准的选用、Pro/E的实体造型过程以及装配和爆炸图的生成等。
本课题中详尽地描述了塑料模具的具体设计过程,首先简明概述该设计的背景知识,接下来进行工艺的计算,然后在工艺计算的基础上对凸、凹模工作部分尺寸进行计算,以便选择其它零件,最后使用在现代设计中应用最广的软件Pro/E对零件进行三维造型、装配和生成爆炸图。

The Design of a Lid workpiece mold design and the 3D modeling of the Die
Abstract: The plastic products are widely used in the area of industry, agriculture, national defense and daily life. Especially in the electronics industry was highlighted. Electronic products, the customer is the most plastic products, improve product performance requirements of high-quality plastic molds and plastic properties, forming process and the design of products.
This design is an electronic product on the lid parts mold design. The focus is on mold design and structure of the design process, including determining the number of cavity; cavity and core size of the calculation; pouring, injection system design; gate sets the choice of type and design of the exhaust system ; Stripping-Die-oriented structure and design; Pro / Engineer presentation; process for the development and shaping the process of calculation; major parts of the structure and terms of the selection criteria; Pro / E of solid modeling and assembly process and Plans such as the formation of the explosion.
The design of a detailed description of the specific plastic mold design process, first of all, concise overview of the design of the background knowledge and technology to the next, and then calculated on the basis of the convex and concave die of the size of the work, in order to choose another Parts and finally the use of modern design in the most widely used software Pro / E for the parts modeling, assembly and production plans of the explosion.
