摘要
对单体缸盖的几种铸造工艺方案进行评述,包括:(1)中部分型,分型面进铁工艺;(2)中部分型,垂直内浇道进铁工艺;(3)侧置顶部雨淋浇注系统工艺;(4)端部顶面压边冒口工艺。指出方案4为最佳方案。用方案4小批试生产K系列缸盖50件,无一件因缩松引起泄漏而报废。
Several casting methods used for single cylinder head was reviewed including: a) parting at middle of casting and gating at the mold joint: b)parting at middle of casting and gating with vertical slot ingates; c) casting being vertically positioned with one of the side surfaces as bottom, gating through the casting top surface with shower gates ; d) gating through a Connor feeder set on the top surface of the end of the casting. It was pointed out that the method d) is the best one. As a trial, this method had been adopted to produce50 pcs of K-series cylinder heads and no one of them was rejected due to shrinkage-caused leakage defect.
