摘 要
模具现在已经成为工业发展的基础，而塑料模占模具总量的比例达到35%~40%，塑料成型模具的应用在各类模具的应用中占有领先地位。注射成型是塑料成型的一种重要方法，它主要适用于热塑性塑料的成型，可以一次成型形状复杂的精密塑件。本课题就是电吹风外壳作为设计模型，将注射模具的相关知识作为依据，阐述塑料注射模具的设计过程。
通过对电吹风外壳成型工艺的分析，本人设计了一副一模两腔的塑料模具。模具中决定塑件几何形状和尺寸的零部件称为成型零件，包括上模板、上模芯、下模板、下模芯、下模镶件等的设计与加工工艺过程。设计成型零部件时，应根据塑料的特性、塑件的结构和使用要求，确定型腔的总体布局，选择分型面，确定脱模方式，设计浇注系统、排溢系统。然后进行成型零部件的结构设计，计算成型零部件的工作尺寸，对关键的成型零部件进行强度和刚度校核。然后运用Pro/E软件完成电吹风外壳模具的整体设计；最后应用Pro/E中的塑料顾问模块（Plastic Advisor），对塑料制品进行注射仿真分析。

Abstract
The design of the Cd-rom shell injection mould Abstract Mould has become the foundation for industrial development ,and plastic moulds account for the Proportion of the total 35%~40%,plastic mould used in the application of various types of mould occupies a leading position .Injection molding is an important method of plastic molding. It mainly suits thermoplastic molding which can be used to shape a precision plastic part in one time. My topic is to explain the design process of the plastic injection mold on the basis of the injection mold-related knowledge, taking the hair dryer enclosure as a design model.
Through analysis of the hair dryer shell molding process, I designed a double-cavity plastic mould. Those parts that deciding the geometrical shape and dimensions of the plastic mold are known as molded parts, including the design and machining process of the upper plate, the upper mold core, the lower plate, the lower mold core, and the inserting of lower mold.While designing molding components, based on the characteristics of plastic, plastic parts of the structure and use requirements, the overall layout of the cavity, the joint face, the stripping methods, design of gating system, exhaust system should be determined. Then structure of molded parts are designed, the working size of the molded parts is calculated, the key molded parts are checked for strength and rigidity. Then use Pro / E software to complete the overall design hair dryer shell mold; and finally the plastic module consultant (Plastic Advisor) in Pro / E is applied for plastic injection simulation analysis.
