Operation principle and beneficial effect
During work, the elasticity thrusting action of elastic cushion block, makes through hole edge the described of core fit together perfectly and contact with the butt face of solid plate along actinal surface;
If all there are wearing and tearing in the described butt face along actinal surface or solid plate of through hole edge core, due to the elastic reaction of elastic cushion block and the regulating and compensating role of compensate for clearance, described the contacting of still can keeping fitting together perfectly along actinal surface and the butt face of solid plate of through hole edge core, thereby avoided described and produced gap between actinal surface and butt face, prevented the generation of goods through hole overlap; The setting of the described holding tank of cover plate is to hold the deformation of truncated cone bottom while compressing for elastic cushion block.
This device makes injection mold avoid often changing the drawback of through hole edge core, has improved mould operational efficiency, has reduced the integrated cost of goods.
Useful design is expanded
This apparatus structure is simple, reliable operation, and wide adaptability, also can be applicable in transverse slider and ejector sleeve.
Above-mentioned, the present invention adopts the device consisting of elastic cushion block, cover plate, through hole edge core, and the boss lower end of through hole edge core is provided with caulking groove, is provided with holding tank above cover plate, through hole edge core slides and is arranged in the edge hole of mould and is fixed by cover plate, elastic cushion block liner is between the through hole edge caulking groove of core and the holding tank of cover plate, between the large step in the Yu Xiang hole, upper end of the boss of through hole edge core, be reserved with compensate for clearance, during work, the elastic reaction of elastic cushion block, the through hole edge upper surface of core and the butt face of mould are fitted together perfectly to be contacted, even if the through hole edge upper surface of core or the butt face of mould all wear and tear, due to the elastic reaction of elastic cushion block and the regulating and compensating role of compensate for clearance, the through hole edge upper surface of core and the butt face of mould still can keep fitting together perfectly contacting, prevent the technical scheme of goods through hole generation overlap, having overcome prior art exists efficiency low, the problems and shortcomings that cost is high, the anti-through hole deburring device of a kind of injection mold providing, make injection mold avoid often changing the drawback of through hole edge core, reached to raising the efficiency, the object reducing costs.
