The present invention relates to the stripper apparatus of injection mold, the pressure that specifically refers to a kind of injection molding mould fixed die slide block for forcing the transverse slider demoulding that makes the cover half place that the is located at injection mold stripper apparatus of loosing core.
Background technology
Injection mold is provided with the injection-molded item of horizontal back-off structure for outer mural margin, adopt transverse slider to make it moulding and the demoulding of loosing core, transverse slider is located at mould dynamic model part conventionally, utilizes the folding of mould, is driven and is resetted or the demoulding of loosing core by the Angle Pin that is located at stationary mould for mould part.
Due to article construction, the transverse slider of some injection mold must be arranged on stationary mould for mould part, is called cover half slide block; The demoulding of loosing core of cover half slide block, consults Fig. 6, and prior art adopts and led by slip Angle Pin, cover half sliding block inclined is loosed core and is separated with goods to downward release cover half when the mould die sinking by spring and elastic resin; In actual injection moulding is produced; because spring and elastic resin are subject to the effect of high temperature, high pressure that swollen dead fault very easily occurs; be that spring and elastic resin are lost or part is lost elastic thrust; cause cover half slide block successfully not loose core and pull goods generation waste product, overall merit is that work is unreliable, and fault rate is high; percent defective is high; cause the integrated cost of goods high, therefore, there are the problems and shortcomings that fault rate is high, percent defective is high, cost is high in prior art.
Summary of the invention
The problems and shortcomings that exist for above-mentioned prior art, the present invention adopts by drag hook, the device that block forms, drag hook is fixedly connected with dynamic model, block is fixedly connected with cover half slide block, when matched moulds, drag hook is connected with block slip hook, when the demoulding, utilize mould die sinking, dynamic model separates with cover half, led by slip Angle Pin, drag hook hook block is forced cover half sliding block inclined to downward pull-out cover half, make cover half slide block and the goods technical scheme separating of loosing core, a kind of pressure of the injection molding mould fixed die slide block stripper apparatus of loosing core is provided, be intended to make the demoulding of loosing core of cover half slide block, reach minimizing fault, eliminate waste product, the object reducing costs.
The object of the present invention is achieved like this: a kind of pressure of injection molding mould fixed die slide block stripper apparatus of loosing core, comprise drag hook and block, wherein: described drag hook is the steel components of leading the quarter bend bulk depending on being L font, the vertical portion of drag hook left part is called left vertical wall, the horizontal component that described left vertical wall lower rightward is protruded is called right planomural, the rectangular through slot that the bottom of the right flank of described left vertical wall is provided with fore-and-aft direction is called hook groove, and the lower cell wall of described hook groove is concordant above with right planomural;
Described block is the steel components of rectangular block shape;
When application, block is fixedly connected on below cover half slide block, drag hook correspondence be fixedly connected on dynamic model above, when mould matched moulds, the left part of block slides and is buckled in the described hook groove of drag hook, drag hook is connected with block hook.
The direction face of said structure statement is divided into up, down, left, right, front, rear side, wherein, before be the face in the face of device front view, after be with described before relative face.
Operation principle and beneficial effect
When the demoulding, mould die sinking, dynamic model separates with cover half, and under the guiding of slip Angle Pin, the pressure of drag hook hook block to downward pull-out cover half, makes cover half slide block loose core out from the horizontal back-off structure of goods cover half sliding block inclined; Spring does not bounce back after extracting out for cover half slide block, and while avoiding cover half slide block to reset, drag hook and block interfere collision.
This apparatus structure is simple, and reliable operation makes the demoulding of loosing core of cover half slide block, has reduced fault, has eliminated waste product, has reduced cost.
Useful design is expanded
This device is applied widely, and for example, the pressure that this device also the can be used for fixed mould lifter piece demoulding of loosing core, consults figure.
Above-mentioned, the present invention adopts by drag hook, the device that block forms, drag hook is fixedly connected with dynamic model, block is fixedly connected with cover half slide block, when matched moulds, drag hook is connected with block slip hook, when the demoulding, utilize mould die sinking, dynamic model separates with cover half, led by slip Angle Pin, drag hook hook block is forced cover half sliding block inclined to downward pull-out cover half, make cover half slide block and the goods technical scheme separating of loosing core, having overcome prior art exists fault rate high, percent defective is high, the problems and shortcomings that cost is high, the pressure of a kind of injection molding mould fixed die slide block the providing stripper apparatus of loosing core, make the demoulding of loosing core of cover half slide block, reach minimizing fault, eliminate waste product, the object reducing costs.
