Description
Technical field
The present invention relates to a kind of injection mold Angle Pin slide block type secondary demolding mechanism, belong to mould of plastics field.
Background technology
At present, adopt mould of plastics to produce similar round plastic smallclothes, such as lid etc., on the bottom surface of this series products, being generally all shaped with annular convex rib or bead, when traditional moulds is produced this series products, is all to adopt immediate roof bar pushing method, withstood on product by the push rod on the upper and lower top board of injection machine ejecting mechanism driven mold, (because the convex tendon of this series products is all very little, very thin, is unsuitable for adding push rod and ejects on convex tendon) is by outside product ejection die.But owing to being shaped with annular convex rib on the bottom surface of product, annular convex rib is embedded in die cavity, the knockout press needing is very large, uses separately the direct ejecting product of push rod, easily product is pushed up to bad, top distortion, causes product rejection.
Summary of the invention
The object of the invention is the shortcoming in order to overcome prior art, a kind of Angle Pin slide block mode that adopts is provided, make push rod Double-ejection, product stripping is smooth, indeformable, do not damage the injection mold Angle Pin slide block type secondary demolding mechanism of quality assurance.
The technical scheme of injection mold Angle Pin slide block type secondary demolding mechanism of the present invention is: comprise that mold cavity and core insert, core is equipped with core plate outside inserting, stripper plate is set in core plate, die cavity, core insert and stripper plate between have the product of moulding, on the bottom surface of product, be shaped with convex tendon, stripper plate matches with the convex tendon of product, core is inserted and core plate is arranged on core fixing plate, mould pin is installed under core fixing plate, mould underfooting is equipped with lower bolster, upper plate and lower roof plate are set between mould pin, on upper plate, connect fore-set, fore-set is connected stripper plate through core fixing plate with core plate, it is characterized in that being shaped with I-shaped groove on described upper plate, on I-shaped groove, slide block is set, the head bevel of slide block, under core fixing plate, connect inclined guide, inclined guide is through slide block, in inserting, core is equipped with push rod, the head of push rod contacts with product bottom surface, the bottom of push rod is shaped with cambered surface, cambered surface matches with the inclined-plane of slide block.
Injection mold Angle Pin slide block type secondary demolding mechanism of the present invention, when the demoulding, first die sinking; core is inserted and is separated with die cavity, then, promotes upper and lower top board, action by injection machine ejecting mechanism; drive stripper plate on fore-set by product jack-up, make the disengaging of inserting of product and core.Meanwhile, slide block, under the effect of inclined guide and I-shaped groove, inwardly slides, and the inclined-plane of slide block contacts with the cambered surface of push rod bottom, sliding in continuing, slide block is by push rod jack-up, and the movement velocity of push rod will be greater than the movement velocity of stripper plate, like this, push rod is by product jack-up from stripper plate, and the demoulding is successful.This programme adopts in Angle Pin guidance tape movable slider sliding, by push rod jack-up, successfully realizes Double-ejection, makes the smooth demoulding of product, enhances productivity, and product is indeformable, do not damage quality assurance.
Injection mold Angle Pin slide block type secondary demolding mechanism of the present invention; described push rod outer wall is equipped with location-plate; on location-plate, be equipped with push rod back-moving spring; assistant ejector pin automatically resets; the head of push rod is equipped with jacking block; jacking block contacts with product bottom surface, ejects easily, reliable, and product bottom surface is top trace not.Described fore-set outer wall is equipped with fore-set back-moving spring, and auxiliary fore-set resets.
