摘　　要：川崎摩托车发动机进气歧管结构复杂。产品侧孔内有斜孔,侧孔抽芯脱模力大,为此设计了2处二次抽芯机构。在动、定模两侧设计了斜顶抽芯机构,为了实现定模侧的斜向抽芯,模具在三板模的基础上增加了一块板,因此模具有4个分型面,为此设计了顺序定距分型机构。结果表明,所设计的模具结构合理,动作可靠,可以满足生产要求。The Kawasaki motorcycle engine intake manifold has a complex structure.A two⁃step core⁃pulling mechanism was designed due to the presence of inclined holes in the holes as well as a strong core⁃pulling force somewhere.A lifter was designed on both stationary half and moving half.A plate was added to the three⁃plate mold for the inclined core⁃pull⁃ing on the stationary half.Aim at four parting surfaces on the mold,a sequential distance parting mechanism was de⁃signed.The results indicated that the mold structure is reasonable,reliable and can meet the requirements of production.
