摘　　要：采用垂直分型造型线生产厚大件时,缩孔、气孔、砂眼、渣眼等缺陷突出,废品率高。以四缸机发动机HT250飞轮为例,对浇注系统中浇道、冒口、排气道等结构进行了重点分析和优化。经过生产验证,基本消除了铸造缺陷,大大提高了成品率,对该类铸件浇注系统的设计有借鉴作用。When using the vertical parting mold lines to produce heavy castings, the defects such as shrinkage,blowholes, sand holes, slag inclusion, and low casting yield rate are serious. Taking HT250 flywheel of four cylinder engine as an example, the structures of sprue, riser and exhaust duct in gating system were analyzed and optimized. After production verification, the casting defects were basically eliminated and the yield was greatly improved, which can be used as a reference for the design of gating system of this kind of castings.
