摘要
压力铸造是目前成型有色金属铸件的重要成型工艺方法。压铸的工艺特点是铸件的强度和硬度较高,形状较为复杂且铸件壁较薄,而且生产率极高。压铸模具是压力铸造生产的关键,压铸模具的质量决定着压铸件的质量和精度,而模具设计直接影响着压铸模具的质量和寿命。因此,模具设计是模具技术进步的关键,也是模具发展的重要因素。
本文介绍了现代模具制造技术的现状及其发展方向,重点说明了铝合金电钻头壳零件压铸模具的设计过程。它主要从产品机壳的工艺分析(主要包括脱模斜度、壁厚、孔、尺寸精度和表面粗糙度、收缩率等),成型方案的确定,压铸机的选用与确定,有色金属压铸模具的几大系统(浇注系统、成型零部件、冷却系统、排气系统、导向系统等)的分析与设计,各种技术数据的校核等方面出发,详细的介绍了压铸模具设计过程中的若干问题。

Abstract
Die-casting molding technology is playing a key role in non-ferrous metal structure forming processes. Die-casting process’s features are the strength and hardness of die casting on high, thin-walled castings plex shape can be cast, and the production is efficient. The die-casting die is the key for
the process of die casting, its quality decides the quality and accuracy of castings, and the design of the die-casting die affects its quality and operating life directly. Therefore, designing the die-casting die is the key to technological progress; it is also an important factor in the development of mold.
This paper has introduced the current situation of the modern mould manufacturing technology and developing direction, have proved especially that the aluminum alloy electric drill shell die casting design process of the mould . It mainly since products craft of chassis analysis (mainly including drawing of patterns slope, wall thick, hole, size precision and surface roughness , shrinking rate ,etc.), sureness of the shaping scheme, exertion and fixing of the injecting machine, Non-ferrous metal casting molds of several big analysis and design of system (pour system , shaping spare part , cooling system , exhaust system , guidance system ,etc.) of mould, the respects , such as check of different technical data ,etc. set out, the detailed introduction injects several questions in the design process of the mould.
key words: Craft analysis Apparatus of shaping Mould structure
