摘　　要：探讨了工艺孔数量及位置对水冷排气歧管铸造性能的影响。使用一种新型排气和支撑两用的芯骨,解决了工艺孔设置较少的排气歧管产品的断芯、呛火、起皮等铸造缺陷,保证铸件的生产,提高了排气歧管产品的铸造成品率,得到客户的认可,并取得良好的效果。This article explores the influence of the number and position of process holes on the casting performance of water-cooled exhaust manifolds.The use of a new type of dual purpose core bone for exhaust and support has solved casting defects such as core breakage,choking,and peeling in water jacket products with fewer process holes,ensured the production of castings,improved the casting yield of water jacket products,gained customer recognition,and achieved good results.
