Secondary Development Of Pro/E For Injection Mold

As outcome of computer science integrated with mold engineering, mold CAD/CAM is a key technology which can accelerate scientific research and transformation of production, make mold designing and manufacturing automatically and expedite mold industry. It is a technique which can improve product designing, shorten the time of developing new product, improve productivity, save the costing of production. To make overseas software be fit to our mold production, secondary development on the commercial CAD/CAM software is an important task which we must face to on generalizing and using mold CAD/CAM in domestic.Pro/ENGINEER is a widly used mold CAD/CAM software. Take it for studying object, With analysis of the development interfaces of Pro/ENGINEER and make comparison for characteristic of Family Table, UDF, Program, J-link, Pro/TOOLKIT, the paper did reserch on methods of sencondary development by Pro/TOOLKIT, such as Pro/TOOLKIT's work mode, designing menu and User Interface Dialog Boxes. The way of Creating application of Pro/TOOLKIT as well as implement of information transformation mechanism between Pro/E and MFC are studied.Second, the paper put much emphasis on parametric design technology of three dimensional solid, the technique of dimension driven, customization templet of planar drawing. Creating, retnevaling and modificating planar drawing view automatically has come true by compiling C programs that Pro/TOOLKIT provides. Dimension and tolerance showing and revising as well as table of drawing create automaticly come true too.Finally, applies above theories, the paper has developed a set of three dimensional parts libary and a set of two dimensional engineering drawing system on the Pro/ENGINEER platform. The system which is for injection mold has a friendly user contact interface, operates easily, is practical. The practice proved that the system can enhance productivity greatly, lighten designer's burden, have high practical value.
