毕业设计-储物桶模具设计与数控加工（三维ProE与MasterCAM自动编程），共34页。共13844个字符数（不计空格）。附cad设计图纸15张
摘要：本文用Pro/E完成储物桶踏板零件的三维造型设计，论文还对分型面、浇注系统、脱模机构和温度调节系统进行了分析设计，完成了模具三维模型和工程图设计。最后采用MasterCAM软件，完成了踏板的凹凸模数控加工的自动编程，并实现了仿真模拟。
通过设计，综合应用了大学期间的多数基础和专业知识，加深所学知识体系，掌握了应用Pro/E进行塑料模具的设计方法和技巧。采用MasterCAM自动编程，使学生掌握刀路设计及参数设计的步骤和原则。

Abstract
This paper describes that how to complete the pedal’s 3D design of storage drum. The irrigate system, parting, shuck institution and temperature adjust system were also designed. The triaxiality models and the schedule drawings of the mould were done. Finally, MasterCAM software will be used to complete the NC automatic programming of pedal bump mould. At the same time, The Simulation will be achieved.
Through this design, the knowledge of more basic and specialty was synthetically applied. The system of knowledge we learned was intensified.
The methods and skills of designing plastic mould with Pro/ENGINEER were mastered. Withing the Automatic programming of MasterCAM, the students have mastered the design of tool path, the steps and the principles of
Parameters designing.
