摘要

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.
