针对铸件在低压铸造过程中产生的气孔、缩松及浇不足的情况,分析了铸件产生缺陷的原因,改变其浇注系统结构,优化铸件排气系统、优化低压铸造参数等工艺措施,成功解决铸件气孔及浇不足缺陷,生产出满足使用要求的铸件。 Aiming at the problems of porosity, shrinkage and insufficient pouring produced during low pressure casting, the causes of casting defects were analyzed, the casting system structure was changed, the castings exhaust system was optimized, the parameters of low pressure casting were optimized, and the casting Stomata and insufficient pouring defects, to produce the casting to meet the requirements of use.
