This paper discussed whether the pouring basin geometry with asymmetric configuration could significantly reduce the porosity defects of an Al-Si7Mg(Fe) alloy (AC4C) castings and whether it could be used for the production of scroll compressors in large quantities according to computer-aided numerical (CAE) method and experiments. The molten aluminum alloy's filling forms were simulated to contrast the molten flow feature of the melt aluminum, which was poured from the typical pouring basin geometry and the proposed counterpart. The CAE simulation shows that the initially symmetric pouring basin causes the molten aluminum to fill at an uneven rate. It is comparatively filled at a relatively smooth filling form in the proposed asymmetric configuration of the pouring basin. The proposed pouring basin geometry resulted in an 85% less porosity percentage. It's concluding that the designed asymmetric pouring basin could be applied in the tilt casting process. By adjusting the geometric feature of outlet shape, different pouring cup volume distribution ratios can effectively reduce the casting defects of a mass-produced scroll compressor.

本文讨论了非对称配置的浇注盆几何形状是否可以显着减少Al-Si7Mg(Fe)合金(AC4C)铸件的气孔缺陷，以及它是否可以根据计算机辅助大批量生产涡旋压缩机。数值 (CAE) 方法和实验。模拟熔融铝合金的填充形式，以对比从典型的浇注盆几何形状和建议的对应件浇注的熔融铝的熔融流动特征。CAE 模拟表明，最初对称的浇注盆会导致铝液以不均匀的速度填充。在倾倒盆的建议的不对称构造中，它以相对平滑的填充形式被相对地填充。建议的浇注盆几何形状使孔隙率降低了 85%。结论是设计的非对称浇注盆可用于倾斜铸造工艺。通过调整出口形状的几何特征，不同的浇杯容积分布比可以有效减少量产涡旋压缩机的铸造缺陷。
