1、外文原文Abstract：Die designing is a demanding and hard work．To design a separate die for each product is time consuming and expensive task．This paper presents an idea of sets of standard reference dies．it gives a concept of

2、flexible die designing using a reference standard die designed in a popular commercial CAD／CAM software—Pro／Engineer．Rather than designing a separate die for each part，just update the die design by selecting the die dime

3、nsions as required．The use of this concept will prove to reduce time and cost of product in manufacturing industry． Key words：die；flexible die designing system ；standardization；Pro/E；secondary developmentAt present, the

4、industrial developed countries and regions in the mold industry has been gradually standardize and serialization. In China, although the majority die within the enterprises have business standards, but generally not high

5、 degree of standardization, standardization of stamping die in the die-limited parts of the parts. To achieve real savings stamping die design time and shorten the processing cycle, cost savings, reduce design and manufa

6、cturing staff workload purposes, it needs to develop a flexible stamping die design system. At the same time, stamping die serialization of the scope of standardization and can not be confined to die-part of the fixed pa

7、nels, boards, the top plate unloading device commonly used components such as stamping or even die structure, we should achieve serialization and standardization.As CAD / CAM technology in the design and manufacture die

8、in the course of extensive application, it should first be standardized stamping die from the CAD system began. Some large-scale commercialization of the CAD / CAM software, such as Pro / E, UG, and so on. Have developed

9、 a specialized injection mold design package. And stamping die design for the special software, users need to be developed.l The application tools Pro / E in stamping die design flexibility in the system development Pro
