根据铝合金壳体压铸件的结构特点,进行了浇注系统设计。利用华铸CAE软件进行了充型过程模拟,根据模拟结果确定在金属液最先、最后充型部位和汇合处,即底部法兰处设置了4个溢流槽,溢流槽外侧设置了排气槽。经生产验证,生产过程中壳体压铸件的气孔等铸造缺陷少,设计的浇注、溢流系统获得了较好的效果。 According to the structural characteristics of aluminum alloy die-casting, casting system design. Based on the simulation results, four overflow tanks were set up at the first and last filling location and the confluence of the molten metal, namely the bottom flange, and the outer side of the overflow tank was provided with rows Gas tank. After production verification, the production process of shell die casting porosity and other casting defects less design pouring, overflow system obtained good results.
