摘要
本文在共注成型多相分层流动充模成型机理的基础上,揭示了芯壳层熔体粘度对共注成型的分层界面形貌和芯层熔体前沿突破的影响,并模拟了芯壳层熔体粘度比对共注成型的影响,建立了芯壳层熔体粘度比与分层界面和前沿移动界面形貌的关系。本文的模拟研究结果与一些文献的实验结果相吻合。
On the basis of the multi-phase flow cavity filling flow mechanism in co-injection molding, we disclosed the influence of the skin and core viscosity on the layer interfacial pattern and the melt front break-through of core, and implemented the numerical simulation of the effect of the core-skin-viscosity rate on co-injection molding, established the relation between the core-skin viscosity rate and the patterns of the layer interface and the moving melt front. The results of case study of numerical simulation have a good agreement with the experimental result given in some literatures.
