Description
Technical field
The present invention relates to the interior arrangement of injection mold, specifically refer to the through hole edge core for injection molded goods through-hole structure, prevent goods through-hole structure from producing the anti-through hole deburring device of a kind of injection mold of overlap.
Background technology
Injection mold is provided with through hole edge core at moulded products through-hole structure place, consult Fig. 3, in mould actual motion, due to wearing and tearing, the through hole edge upper surface of core and the butt face of mould can produce gap, cause the bead of goods through hole 06 to produce overlap, cause product property bad; Prior art is taked when goods occurring being bad; timely replacing through hole edge core; change through hole edge core to need to shut down; dismounting mould, time-consuming, mould operation expense is high; production efficiency is low; goods integrated cost is increased, and therefore, there are the problems and shortcomings that efficiency is low, cost is high in prior art.
Summary of the invention
For above-mentioned prior art Problems existing and deficiency, the present invention adopts and inlays by elastic cushion block, cover plate, through hole the device that core is formed, and the boss lower end of through hole edge core is provided with caulking groove, is provided with holding tank above cover plate, the slip of through hole edge core is arranged in the edge hole of mould and is fixed by cover plate, elastic cushion block liner is between the caulking groove and the holding tank of cover plate of through hole edge core, compensate for clearance is reserved with between the upper end of the boss of through hole edge core and the large step in edge hole, during work, the elastic reaction of elastic cushion block, the through hole edge upper surface of core is fitted together perfectly with the butt face of mould contact, even if all wear and tear in the through hole edge upper surface of core or the butt face of mould, 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 still can keep fitting together perfectly contacting with the butt face of mould, prevent the technical scheme of goods through hole generation overlap, there is provided a kind of injection mold anti-through hole deburring device, be intended to make injection mold avoid often changing the drawback of through hole edge core, reach and raise the efficiency, the object reduced costs.
The object of the present invention is achieved like this: the anti-through hole deburring device of a kind of injection mold, comprises elastic cushion block, cover plate, through hole edge core, wherein: described elastic cushion block is the polyurethane matter elastomeric elements of Upper cylindrical shape, lower cone platform shape;
Described cover plate is the steel components of rectangular block shape, and the circular groove that is provided with above of cover plate is called holding tank;
Described through hole edge core is the steel components of up-small and down-big cylinder step, and the bottom of through hole edge core is provided with flange and is called boss, and the lower surface of described boss is provided with circular groove and is called caulking groove; The upper surface of through hole edge core is called along actinal surface;
When application connects, through hole edge core slides and is arranged in the edge hole of mould, the lower surface of inlaying the described boss of core above with through hole of cover plate contacts, cover plate and being fixedly connected with moving platen, elastic cushion block liner is between the described caulking groove and the described holding tank of cover plate of through hole edge core, and between the upper surface of the described boss of through hole edge core and the large step end face in edge hole, the spacing be reserved with for Compensation Regulation is called compensate for clearance.
Operation principle and beneficial effect
During work, the elasticity thrusting action of elastic cushion block, described the fitting together perfectly with the butt face of solid plate along actinal surface making through hole inlay core contacts;
If the described butt face along actinal surface or solid plate of through hole edge core all there occurs wearing and tearing, due to the elastic reaction of elastic cushion block and the regulating and compensating role of compensate for clearance, the described butt face along actinal surface and solid plate of through hole edge core still can keep the contact fitted together perfectly, thus avoid and describedly produce gap along between actinal surface and butt face, prevent the generation of goods through hole overlap; The setting of the described holding tank of cover plate, holds the deformation of truncated cone bottom when being and compressing for elastic cushion block.
This device makes injection mold avoid the drawback often changing through hole edge core, improves mould operational efficiency, reduces the integrated cost of goods.
Beneficial design is expanded
This apparatus structure is simple, and reliable operation, wide adaptability, also can be applicable in transverse slider and ejector sleeve.
Above-mentioned, the present invention adopts and inlays by elastic cushion block, cover plate, through hole the device that core is formed, and the boss lower end of through hole edge core is provided with caulking groove, is provided with holding tank above cover plate, the slip of through hole edge core is arranged in the edge hole of mould and is fixed by cover plate, elastic cushion block liner is between the caulking groove and the holding tank of cover plate of through hole edge core, compensate for clearance is reserved with between the upper end of the boss of through hole edge core and the large step in edge hole, during work, the elastic reaction of elastic cushion block, the through hole edge upper surface of core is fitted together perfectly with the butt face of mould contact, even if all wear and tear in the through hole edge upper surface of core or the butt face of mould, 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 still can keep fitting together perfectly contacting with the butt face of mould, prevent the technical scheme of goods through hole generation overlap, overcoming prior art, to there is efficiency low, the problems and shortcomings that cost is high, the anti-through hole deburring device of a kind of injection mold provided, injection mold is made to avoid often changing the drawback of through hole edge core, reach to raising the efficiency, the object reduced costs.
