【摘要】：针对低压铸造加工全封闭式组合电器铝合金罐体产品合格率低的问题,通过ProCAST软件对原铸造工艺进行模拟。通过对比试验,并结合企业实际,确定优化工艺参数,并对铸件形状及浇注系统进行改进,消除了铸件缺陷。研究表明,浇注温度为700℃、充型压力为54kPa、模具预热温度为300℃时,对铸件下半部外侧壁厚增大1.5mm,形成适当厚度梯度,并将原浇注系统内浇道宽度增加7mm,可以消除铸件缺陷,提高铸件品质。
[Abstract]:In order to solve the problem of low qualified rate of aluminum alloy tank in low pressure casting process, the original casting process was simulated by ProCAST software. Through contrast test, combined with enterprise practice, the optimization process parameters were determined. The casting shape and gating system were improved, and the defects of the casting were eliminated. The results show that when the pouring temperature is 700 鈩，
