摘要
以LJ465Q-lA曲轴箱为例.对微型车用发动机曲轴箱铸件在铸造生产中出现的气孔缺陷成因进行了研究分析.从浇注系统、浇注温度、砂芯质量等方面提出了应对措施.解决了铸件的气孔缺陷。
Taking Crankcase LJ465Q-lA for example,the cause of blow hole defect in engine crankcase castings used in micromotor was analyzed.The solutions were put forward in pouring system,pouring temperature,sand core quality.The defect was eliminated.
