摘　　要：针对新型气缸盖短周期开发需求,结合某气缸盖的结构特点,采用外形砂型精密加工形技术结合砂芯喷墨打印制备铸型,1箱1件,人工组芯造型,侧浇底注成形铸件。生产验证结果表明,该方案设计合理,产品合格率高,与传统方法比较,铸造周期从75天左右缩短至10~30天。According to the short cycle development demand of the new cylinder head, combined with the structural characteristics of a cylinder head, the shape of sand mold was prepared by inkjet printing and the sand core was processed by precision machining technology. Casting was formed by 1 piece in 1 box, artificial core forming, side pouring and bottom gating. Production verification results showed that the design of the scheme was reasonable, the product pass rate was high, and the casting cycle was shortened from about 75 days to 10-30 days compared with the traditional method.
