【摘要】 近年来，模具工业发展迅速，CAD／CAM技术在模具设计生产方面的应用，起到了至关重要的作用，它被认为是现代模具技术的核心和重要的发展方向。Pro／ENGINEER(以下简称Pro／E)作为全球最完善的模具设计软件，广泛应用在我国模具行业中。 不过，在国内的一些公司和企业中，Pro／E作为一种软件工具，主要还是集中在辅助设计的应用之上，而对于该软件的二次开发却相对严重滞后，其他软件的情况也是一样。所以以商品化的CAD／CAM软件为平台进行二次开发，使国外这些软件工具适合我国生产的设计要求，是很有必要的，这也是目前国内在使用国外的CAD软件时的一项重要工作。对Pro／E进行二次开发，对于我国的企业来说，有着很大的意义，它不仅可以使软件适合国内企业的设计要求，还可以大大地节省设计成本和人力物力，缩短生产周期，给我国的模具工业生产带来很大的方便。 一般来说，对Pro／E进行开发有两种方法，第一种是利用该软件自带的PROGRAM语句进行开发，第二种是利用Pro／E的Pro／TOOLKIT模块，通过编写C语言代码来进行开发。Pro／TOOLKIT为用户程序、软件及第三方程序提供了与Pro／E的无缝联接。它提供了大量的C语言的库函数，能够使外部应用程序安全有效地访问Pro／E的数据库和应用程序。 本文对Pro／TOOLKIT的开发方式及步骤进行分析和研究，得出了利用Pro／TOOLKIT对Pro／E进行二次开发的完整方法，并应用于实际的模具设计中。通过对三维弯管芯模的设计和生产工艺进行分析，开发出了芯模的工艺参数计算分析模块，简化了工艺参数的计算步骤，显著提高了生产效率；对模具标准系列零件进行概述和分析，通过对Pro／E软件中的系列零件的尺寸驱动方法进行分析，丌发出了改善系列零件尺寸驱动方法的功能模块，使其更符合人们设计的习惯和要求，以提高标准系列零件的设计效率；对虚拟装配技术进行研究分析，并结合具体模具的装配，开发出了模具装配的虚拟仿真模块，并仿真其中的机构零件运动，方便进行干涉检验，使装配结构更直观明了。 结合模具CAD对Pro／E二次开发进行研究，可以更好地发挥Pro／E软件的设计功能，对模具CAD技术的发展也有着很重要的意义。更多还原

【Abstract】 In recent years, the mold industry was developed quickly. The uses of CAD/CAM technology in mold designing and manufacturing were very important. CAD/CAM technology is considered the core and developing direction of modern mold technology. Pro/ENGINEER which is one of the best software in mold designing, is used widely in our mold industry.However, in some domestic corporations and enterprises, as a software tool, Pro/E was mainly used in aided designing, the further development on Pro/E was relatively lagged. Other software is just the same. So it is necessary to further develop these CAD/CAM software to make them be fit to our industry, which is one of the important work in using thee external software. Further development on Pro/E is significant to our corporations, which can not only make it meet to the need of mold design, but also save the design costing and resource, and shorten the manufacturing cycle, which bring convenience to our mold industry.In general, there are two ways to further develop Pro/E. One is developing by its own PROGRAM code, the other is developing by Pro/TOOLKIT and making C program. Pro/TOOLKIT which provides the connection with Pro/E for user’s program, software and the third program, offer a large amount of C library functions and make the external program visit the Pro/E data and application safely and effectively.This article analyzes and researches the ways and steps of Pro/TOOLKIT, conclude the intact ways of developing by Pro/TOOLKIT, and used these ways in practical mold design. By analyzing the technology parameters of pipe mold, develops the application program of computing technology parameters of pipe mold, simplifies the computing course, improves markedly the manufacturing effective of pipe; by elaborating the standardized series parts of mold and analyzing the measures of dimension driving in Pro/E, develops the applicant program which reform the ways of dimension driving about series parts, making it fit to designing customs and demands. It can improve the design effective ofmold standardized series parts. By researching the subjunctive assemble technology, develops the simulation parts of mold assemble. It can simulate the motion of mechanical parts in the assembly to check interference conveniently and clear the assemble structure.Researching the further development on Pro/E connecting with mold CAD can develop the design function of Pro/E software, and is significant to the development of CAD technology of mold.更多还原
