摘要
在注塑模设计中,浇注系统的设计对塑料成型的质量影响很大。针对一模八腔的非平衡浇注系统,运用MPI技术,给出了通过优化分流道尺寸来获得平衡的流道系统的过程,结合模拟分析结果对分流道尺寸作出修改,最终得到了分流道尺寸的最佳值,从而保证熔体能够基本上同时充满型腔,实现浇注系统的人工平衡,提高了一次试模的成功率。
In the injection mold design, the runner system has a great influence on the molding quality. For an one-mold eight-cavity with non-balance runner system, the process of balance runner system was obtained through optimum divided runner size with MPI. According to the results of simulative analysis, revised the divided runner size, and finally the best value of divided runner size was achieved. Thus can make sure that the various cavities were filled at the same time, and the runner system is artificial balanced. As a result the success rate of trial molding is increased.
