摘　　要：精密铸造工艺对于小件、单件的组树效率较低,组树件数较少,铸件的工艺出品率相对较低,同时在后处理环节切割以及浇口打磨工序的成本较高,效率较低。采用类树枝状的组树方式,可以大幅提升组树件数和组树效率,同时提高铸件的工艺出品率。改用易割浇口代替直浇道,可以降低金属损耗,提升切割打磨效率,从而降低铸件的综合成本。For small pieces by investment process,the tree assembling efficiency of single piece is low with small quan⁃tities,and the yield rate of castings is relatively low.Meanwhile,the cost of cutting and grinding gate in the posttreatment process is higher with low efficiency.The tree assembly similar to dendrimer was adopted,which could greatly improve quantities and efficiency of tree assembly as well as the yield rate.A straight gate was replaced with cut-free gate,which could decrease the loss of metal and improve cutting and grinding efficiency,thus reducing the overall production cost.
