The Injection Mold The Top Of The Bodies Of Intelligent Design Systems Research And Development

The intellectualized design system for ejection system of plastic injection mold is an intelligent software integrated into the platform of AutoCAD2000.Its aim is to realize the intelligent selection for ejecting way of any common plastic product and automatic generation for the according 3D model of ejection system.This system is composed of three modules. They include the module of expert'system of selecting ejection ways, the module of reasoning and calculating the size of ejection parts and the module of 3D modeling for ejection system.When selecting ejection ways of plastic products, the technology of artificial intelligence will be introduced to establish expert system for intelligently selecting ejection ways. Comprehensively applying object-oriented technology, database technology and fuzzy theory, this expert system represents, saves the knowledge for selecting ejection way and make reasoning efficiently to acquire the appropriate ejection way conveniently.With calculating formula for the size of ejection parts transformed into programming code and encapsulated into module; with plastic properties .etc saved in database, when plastic product's inside diameter and wall thickness .etc are inputed, the value of stem diameter or upper plate's depth will be acquired rapidly, so designers can be free from heavy calculation and be concentrated on creative design with more energy.The size parameter of ejecting part, return part and guide part in ejection system are saved in SQL Server2000 and modeled into 3D solid by integrating VC++6.0 with ObjectARX2000 on the platform of AutoCAD2000.Finally, these 3D solid models of standard parts are assembled into a complete 3D solid model of ejection system.By using technology of man-machine interface, a user-friendly visual special menu is customized based on the interface of AutoCAD2000,so that the three modules are all integrated into the platform of AutoCAD2000 to form an interactive entirety-the intellectualized design system for ejection system of plastic injection mold.This paper is just an important part of intelligent CAD system for plastic injection mold. Its research and realization have application and reference value for mold development.
