摘　　要：建立了钢塑共挤模具的三维模型,通过在Gambit中进行有限元前处理,导入Polyflow,对过渡拖动段成型的基本规律进行了数值模拟,获得了聚合物熔体在模具内的速度场、温度场分布,在特定流量下,分析了不同钢衬拖动速度对聚合物流动的影响规律,并在此基础上设计了钢塑共挤模具冷却系统。A 3D model for co-extrusion dies of shaping rules of transition driving section polymer with metal insert was established. The were numerically simulated by using Polyflow basic after pre-processed in Gambit. The distribution of temperature and velocity field of polymer melt in the die was achieved and the effect rule of various driving velocity in steel liner on the polymer flow was analyzed. Based on it, a cooling system of co-extrusion dies of polymer with metal insert was designed.
