摘　　要：针对砂型铸造生产大、中型薄壁油底壳类铝合金铸件,容易出现浇不足、夹渣、砂眼等铸造缺陷,根据多年生产实践经验总结,通过采用带过滤网的搭接式双向横浇道的浇注系统和组芯工艺,大大提高了铸件合格率,可以稳定生产出优质合格铸件。The large and medium-sized thin wall oil pan of aluminum alloy castings has casting defects such as misrun, slag inclusion, sand inclusion, etc. According to production experience, by adopting lap jointed two-way runner gating system with screen and core assembly process, the yield of casting improved, and it could stably produce a high-quality qualified casting.
