摘要
以汽车变速箱体零件为模型,运用Magma软件。模拟变速箱体在铸造过程中的充型流态,并对模具进行温度场模拟,分析定模、动模在喷涂前后的温度场状况。通过多组的工艺参数组合模拟,最后得到较好的模拟状态。由生产试验得知,在模具实时温度控制中,参数化调节是困难的。通过先行在Magma中模拟缩小工艺参数区间,将模拟的参数复制到压铸机上,通过微调得到理想模具温度,解决产品压铸的品质问题。能有效降低产品报废率,提高设备综合效率。
Taking the automobile gearbox parts as an example, the filling of high pressure die-casting mold and mold＇s temperature field were simulated using Magma software. By the analysis of the temperature field in fixed mold, moving mold, the better simulation state was obtained. Production test found that it is difficult to adjust the parameters in real time temperature control of the mould. By Magma simulating analysis, process parameter interval can be reduced, the ideal mold temperature can be obtained and the quality problem of die-casting can be solved after the simulation parameters are copied to the die-casting machine. The product scrap rate and OEE can be effectively increased.
