Description
Technical field
The present invention relates to metal die-casting mold and plastic injection mould, it is oblique top and air pressure
Cylinder combines the mold mechanism of core pulling.
Background technology
Mould is after product moulding by casting, if the side wall of product has inner convex platform or outer recessed,
Will first externally recessed row core pulling, then product inner convex platform is deviate from from core after die sinking.It is existing
Have technology be in die sinking by the external recessed row side core-pulling of Angle Pin and spring band movable slider,
Complete the core pulling of product inner convex platform with movable slider by spring or brace again, finally will by thimble
Product is from building core outside launch mode.The structure uses Angle Pin and spring due to outside
Side core-pulling is driven, spring fatiguability failure, Angle Pin is stuck easily in slide guide hole, therefore
Easily mold damage in production.And inside drives sliding block complete using spring and inclined guide
Into the core pulling of product boss, because the size inside product and position are limited, therefore inside
