摘　　要：为解决铸件气缩孔问题,在压铸模定模侧设计了一种组合型芯反推式斜抽机构。在铸件定模侧存在大量斜孔无法直接出镶针的情况下,采用该机构能够将这些孔位做成整体斜抽。该新型反推式斜抽机构设计精巧,运行平稳,故障率低,使用可靠,值得推广应用。To reduce or eliminate the blowhole shrinkage defect of die castings,a new kind of reverse push type inclined pulling mechanism for the fixed die side of die casting die was designed.When there are a large number of inclined holes on the fixed die side of the casting which cannot be made into inset pins,we can make these holes into integral oblique drawing by using this mechanism.This kind of fixed die reverse push type inclined pulling mechanism is exquisite in design,stable in operation,low in failure rate and reliable in use,which is worthy of popularization and application.
