Moldflow在仪表盒盖注塑模具设计中的应用
|
摘要
Moldnow是著名的注射模CAE软件,具有强大的仿真分析、可视化和项目管理功能。仿真结果的准确性对模具设计和制造以及注塑生产的经济效益具有重要意义。以仪器箱盖为研究对象,确定了最佳浇口位置。分析了熔体充型时间、前沿温度、体积剪切速率和熔体流动压力分布,空化和焊缝的位置,通过仿真结果找出了缺陷产生的原因,并对工艺参数进行了改进。
Moldnow is a famous injection mold CAE software. It has powerful functions of simulation analysis, visualization and project management. The accuracy of simulation results is of great importance for the design and manufacture of moulds, as well as the economic efficiency of injection molding production. The optimum gate position is determined for the cover based on the research doject of the instrument box. The filling time, the front temperature, the volume shear rate and the pressure distribution of the melt flow, as well as the position of the cavitation and weld marks were analyzed. The cause of the defect is found through the simulation results, and the process parameters are improved.
