Design of injection mold with two-step core-pulling mechanism for intake manifold of a motorcycle engine
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.
