摘要：粉末冶金是一门制造金属与非金属粉末和以其为原料（复合材料），经过压制、烧结及各种后续处理工艺制取金属材料和制品的科学技术，它是一项以较低的成本制造高性能粉末冶金制品的技术。本次毕业设计主要介绍粉末冶金模具设计的一般过程，是针对铁基齿轮这个具体产品来进行设计的。在设计中进行的一些工作有：产品材料选择，压制设备选择，设计参数选择（像烧结收缩率、压制回弹率），模具尺寸及精度计算，模具材料选择，热处理分析，模具结构分析及选用，模具成形及装配，图纸的绘制。其中，模具成形及装配是借助于pro/e三维软件进行的，摆脱了复杂零件模具设计的复杂，减轻了工作任务。再把三维模具零件图向二维工程图转化。在设计工作中，图纸的绘制有很大一部分在二维AutoCAD软件中进行，像尺寸标注，标题栏创建，示意图绘制。

Abstract： Powder metallurgy is a technique, which uses metallic and non-metallic powder (composite) to produce metallic material and parts through compction, sintering and post treatment, and which is used for forbricating high performance ferrous parts at a low cost. This graduation design primarily introducted the general process about the mould design of powder metallurgy, it carried on the design work to a concrete product what is the gear with iron base. In the course of design, some jobs which were launched included the choice of product material, the choice of repressive device, the choice of design parameter( for example, the shrinkage from the sinter and rebound proportion after compaction ), mould dimension and precision calculation, the choice of mould material, the heat treatment analysis, the analysis and choice of the mould construction, the mould shape and assemble, the drawing. Among these, the mould shape and assemble were finished by means of pro/e software. It unloaded the complexity of the mould design to the complex part, and relieve the assignment. Then, the pro/e software translate the three-dimensional mould part into two-dimensional engineer drawing. In the course of design work, the drawing mostly finished through the AutoCAD software, for example, the label of the part size, the creation of title column, the drawing of the other schematics.
