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.
Abstract
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.
