Research On CAD Of Mould Based On Further Development Of Pro/ENGINEER Software

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.
