Injection Mold Molding Process Simulation And Optimization

In recent years, Mould industry makes rapid progress and plays a important role in national economy development. However, the property of plastic material itself and the complexity of processing conditions make the process of the injection molding quite complicated. For a long time. The control of process of plastic injection molding and mold design and manufacture mainly depend on experience of designer and technique of the technologist. The rationality of design and the quality of product which can be seen after mold test. It brings about long design cycle and high manufacture cost. Because the time our country research macromolecule material and plastic processing is relatively late, we lag about years 20 than foreign in this field.This article introduces particularly the defect of product on the processing of plastic injection and the reason of causing those problems. Meanwhile, giving the ways to solve those defects.By establishing the physical and mathematical model of injection molding process and adopting effective numerical algorithm, optimizing simulated numerically algorithm on the process of plastic injection. The mean which optimizing the placement of plastic mold gate is discussed in the article, Aiming at that melt can reach the extremities of the cavity at the same time and reduce the warpage of the parts.Moreover, using the theory to resolve some problem in actual procession and validating the validity of the theory...
