Research On Knowledge Base And Reasoning System Of Injection Mold's Side Action

With advancement of technology and high-speed development of world, upgrade and innovation of products are speeded up. No matter what industrial products and appliance, are mostly molded by mold. Therefore, plastic parts' design advances higher demands for periods and precision of mold design and manufacture. Because mold design depends on designers' experience and knowledge completely by traditional CAD softwares, so efficiency and quality can't completely satisfy the demands of mold development.So intelligence and automation are very important in mold design. This issue has joined the expert system to mold design, and developed an intelligentized injection mold design system. Basing on the plastic parts' information, the system can implement automatically reasoning and analysis by the interrelated knowledge, and select an relevant model from the model base, then rebuild the model by parameterized technology, finally finish the design process of injection mold. The entire design process is completed by computer automatically without the calculation of designers, which decreases flaws caused by lack of experience of mold designers, and helps to avoid mistakes and improve efficiency and quality of mold design.This paper summarized the design knowledge of injection mold's side action; then builds knowledge base suing the hybrid representation of frame representation and rule representation; and introduces the principles, process and method of computer automatic design system for side action in detail; Taking the best quality of plastic parts and highest efficiency as main purpose, this paper finally develops side action; and also builds the graph library of side action using parameterized technology based on SolidWorks. In information management system, plastic parts are dealed with in aspect of shrinkage and draft, which will make models more precision for the next design. An actual process of the mold design for a typical plastic part has been demonstrated, which shows that the idea of system is feasible and this system can be used expediently to satisfy the demands of mold design.This paper also investigates menu and interface of this software, and finally designs a laconic, intuitive and manipulated friendly interface for injection mold design in order to make this software more acceptable to users.
