摘要
采用动态工况与液固耦合技术对振动工况下压铸模所需最小锁模力进行模拟分析,结果表明:金属液充型过程中型腔壁面最大等效应力节点都集中型腔边缘处的相同位置,上模芯和下模芯的反作用力分别为31.344N和34.012N,最小锁模力为65.356N,同时振动工况会导致锁模力增大。模拟分析结果可为压铸生产获得合理的工艺参数提供参考。
Simulation analysis was made on the minimum clamp force of die-casting die in vibration working condition by using dynamic working condition and liquid-solid coupling technology. The result shows that the maximum equivalent stress node of cavity wall in the liquid metal filling process all concentrates at the same position of cavity edge; the re active force of upper and lower die cores is 31.344N and 34.012N, respectively; the mini mum clamp force is 65.356N; and the clamp force can be increased under vibration work- ing condition.
