Description
Technical field
The present invention relates to a kind of injection mold Angle Pin slide block type secondary mould emptier, belong to the mould of plastics field.
Background technology
At present, adopt mould of plastics to produce similar round plastic smallclothes, for example lid etc.; Generally all being shaped on annular convex rib or bead on the bottom surface of this series products, when traditional moulds is produced this series products, all is to adopt direct push rod pushing method; The push rod that is promptly driven on the upper and lower top board of mould by the injection machine ejecting mechanism withstands on the product; (because the convex tendon of this series products is all very little, very thin, be inappropriate on convex tendon, add push rod and eject) ejects product outside the mould.But owing on the bottom surface of product, be shaped on annular convex rib, annular convex rib is embedded in the die cavity, and the knockout press that needs is very big, uses push rod directly to eject product separately, easily product is pushed up bad, top distortion, causes product rejection.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of prior art, a kind of employing Angle Pin slide block mode is provided, the push rod secondary is ejected, product stripping is smooth, and is indeformable, do not damage the injection mold Angle Pin slide block type secondary mould emptier of quality assurance.
The technical scheme of injection mold Angle Pin slide block type secondary mould emptier of the present invention is: comprise that mold cavity and core insert, core is inserted and is equipped with core plate outward, and stripper plate is set on the core plate; Die cavity, core insert and stripper plate between the product of moulding is arranged, be shaped on convex tendon on the bottom surface of product, stripper plate matches with the convex tendon of product; Core is inserted and core plate is installed on the core fixing plate, and core fixing plate is installed the mould pin down, and the mould underfooting is equipped with lower bolster; Upper plate and lower roof plate are set between the mould pin, connect fore-set on the upper plate, fore-set passes core fixing plate and is connected stripper plate with core plate; It is characterized in that being shaped on the I-shaped groove on the described upper plate, on the I-shaped groove slide block is set, the head bevel of slide block; Under core fixing plate, connect inclined guide, inclined guide passes slide block, in core is inserted, is equipped with push rod; The head of push rod contacts with the product bottom surface, and the bottom of push rod is shaped on cambered surface, and cambered surface matches with the inclined-plane of slide block.
Injection mold Angle Pin slide block type secondary mould emptier of the present invention, during the demoulding, at first die sinking; Core is inserted and is separated with die cavity, then, promotes upper and lower top board, action by the injection machine ejecting mechanism; Drive stripper plate on the fore-set with product jack-up, make the disengaging of inserting of product and core.Simultaneously, slide block inwardly slides under the effect of inclined guide and I-shaped groove, and the inclined-plane of slide block contacts with the cambered surface of push rod bottom; Sliding in continuing, slide block is with 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 product jack-up from the stripper plate, demoulding success.This programme adopts in the Angle Pin guidance tape movable slider sliding, with push rod jack-up, realizes that successfully secondary ejects, and 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 mould emptier of the present invention; Described push rod outer wall is equipped with location-plate, is equipped with the push rod back-moving spring on the location-plate, and assistant ejector pin automatically resets; The head of push rod is equipped with jacking block; Jacking block contacts with the product bottom surface, and it is easy, reliable to eject, and the product bottom surface is the top trace not.Described fore-set outer wall is equipped with the fore-set back-moving spring, and auxiliary fore-set resets.
