Computer Aided Design And Manufacturing Of The Die-casting Mold

Throttle body is a key part of engine, its quality will directly effect engine performance and safety of the automobile, With the automobile competition having transformed into the cost competition . prolonging die set life-span, cutting down reject rate and product cost are the urgent matter for the enterprise of auto parts production .Three dimensional structure of the throttle body die set and computer aided numerical control technology are designed for the die set CAD/CAM integrated technology design and manufacture by CAD/CAM . Casting system and coolant system are proofed to improve the die set design optimization in design computing . Simultaneously, die-casting technology parameter are designed optimally to improving product quality. The main researches are followed as:(1) Basing on referring lots of the literature domestic and abroad amply, the article reviews the actuality of the die-casting mold design and manufacture, the life stats, the development, the research of the die-casting mold, and the trend of the die-casting mold CAD/CAE/CAM technology. Know and master the information on the current domestic and abroad die-casting mold life stats, combine the enterprise stats, and advance the study means of this lesson , it is: CAM/CAM IntegrationApplication-Key Design Parameter Analysis Calculation-Techniques Parameter Optimize Design.(2) The article expounds the structure and shape of the throttle body, the art and technology of the parts etc. The technology of the part determines the quality of the parts and the life of mould. Simultaneously , it has advanced the basic require of the mould during the aspect from the design principle, assemble, test, material and heat treating, intensity and cost, and mould shelf. So it has ensured the collective idea of mould design.(3) To the entity sculpt system of the basic character parameter , it is sure to accomplish the mould CAD three-dimensional entity sculpt by basic body character .draft , figuration character and character operation. It makes sure the mould correlative parameter through the academic calculation of the molding system and the refrigeration.(4) For the mould structure character, combining the actual instance of the current stats numerical control equipment and cutters and so on, it draws out mould machining art project. Using perfect means provided by Delcam set the numerical control machining of the coarse and elaboratemachining .examine the interference collision for the clincher , pole by the emulation software machining module, and make sure the operational progress of the part numerical control machining.(5) Through the die-casting art parameter optimizing design of the pressure, effluent speed, filling time, fast effluent transition location and so on, it makes sure the perfect art parameter, and improves the production quality by experiment validate.
