Injection Mould Cae Of The Complex Plastic Parts Of The Car

Nowadays, more and more industrial departments use plastic parts with the rapid development of the plastic industry, which demands better and better quality of the injection moulds. So the traditional design of the moulds can't adapt it. The injection mould CAE can analyze and simulate the molding process in computer and forecast the disadvantages of the design before the injection moulds are made. This simplifies the conventional means of testing moulds repeatedly and repairing moulds on the injecting molding machine. Compared with the traditional design way of the injection moulds, CAE can increase the productivity, get good quality of moulds and parts, reduce cost and lessen labor intensity, and it will play a tremendous role in plastic industry. This paper uses Moldflow/MPI to analyze the mould of the plastic part of the Sai-ma cars, including pre-analyzing the molding process and choosing the molding parameters, doing flow analysis, cooling analysis and warp analysis of three molding scheme, simulating how the plastic polymer filling, packing and cooling in the mould and forecasting the stress distributing, volumetric shrinkage and warp etc, then choose the best molding design. At last, optimize the best molding design including the molding parameters such as mold temperature, melt temperature etc in order to get the best injection molding part with the lowest cost and the highest productivity.
