Abstract

With the development of polymer materials, the application scope of injection molding products is becoming more and more extensive. This is becoming more and more demanding for the injection molding process, especially the products with high requirements for the thin wall, surface and strength of the injection molding, in addition to the requirements of its use, the traditional injection molding is difficult to be processed and complicated. Plastic parts. It is difficult to form high quality thin-walled plastic parts. Injection compression is a kind of precision injection molding. The process parameters affecting the quality of the plastic parts have many and mutual influence. The evaluation of the quality of the plastic parts should be judged from multiple targets. The advantages of injection-compression molding process on this paper. It can reduce the residual stress of the molding. So most of the optical plastic parts are produced by this method. In this paper, the Taguchi method of 5 levels and 6 factors was established on the basis of Minitab. Taking the shell of the computer display as the research object, the injection compression molding process under different technological conditions was simulated and analyzed. The maximum warpage deformation, the average weld line and the average volume contraction rate of three target values were analyzed respectively. Through the difference analysis, the influence degree of 6 process parameters, die temperature, melt temperature, compression force, compression speed, compression distance and compression time, is determined, and the corresponding trend diagram is drawn.
