Abstract
The utility model belongs to the technical field of the injection mold technique and specifically relates to a correct a long and thin injection mold structure of warping of moulding, including movable mould, cover half, ejector pin, the cover half on fixed surface be equipped with down the cavity, the movable mould under fixed surface be equipped with the upper plenum, the upper plenum constitute with lower cavity and mould an appearance, ejector pin bottom fixed connection cover half, the movable mould fixed set up with the same through hole of ejector pin diameter size. The utility model discloses a correct a long and thin injection mold structure of warping of moulding optimizes forming technology through improving, makes predeformation to the mould and revises, has realized plastic product one shot forming, need not the later stage adjustment, has solved a long and thin problem of being out of shape of moulding.
Description
Technical field
The utility model relates to injection mold technical field, especially a kind of injection mold structure correcting the distortion of elongated plastic.
Background technology
Plastic mould is a kind of abbreviation of the built-up plastics mould shaping for compression moulding, extrusion molding, injection, blowing and low ratio foamed, mainly comprise the die with variable impression be made up of die set substrate, die assembly and die set clamp, combine clamp, die cavity by punch assembled substrate, punch assemblies, punch and block assembly and side and cut the punch with variable core that compoboard forms.Mould punch and matrix and assistant formation system coordination change.The serial plastic of difformity, different size can be processed.
In recent years, fast-developing in modernization mould industry, plastic mould is widely used in the industrial production, the structural requirement of plastic mould is more and more higher, especially for the fast development of automobile industry, automobile plastic cement part shape of product becomes increasingly complex changeable, and plastic mould enterprise also must meet structure and the dimensional requirement of auto parts, and some traditional Mould design and manufacturing technology cannot reach the production requirement of auto parts.
The long weather strip of vehicle dormer window belongs to elongated working of plastics, after opening molding jig by digital-to-analogue completely, because of plastic material be flexible glue and product structure problem easily produce shaping after contraction distortion.Because of the composite factor of above two aspects, the data of deflection cannot be predicted before system opened by mould, can not ensure that product reality can reach size and deflection requirement by the deflection after mold flow analysis, especially for strip flexible glue product, only be difficult to thoroughly solve by moulding process.
Utility model content
The technical problems to be solved in the utility model is: in order to solve Problems existing in above-mentioned background technology, provides a kind of injection mold structure correcting the distortion of elongated plastic, solves the problem of traditional product distortion.
The utility model solves the technical scheme that its technical problem adopts: a kind of injection mold structure correcting the distortion of elongated plastic, comprise dynamic model, cover half, push rod, described cover half upper surface is fixed with lower cavity, described dynamic model lower surface is fixed with upper plenum, described upper plenum and lower cavity form plastic profile, described push rod bottom is fixedly connected with cover half, and described dynamic model fixedly offers the through hole the same with push rod diameter.
Preferably, locating piece is fixedly installed in the middle part of described cover half upper surface corner and two long limits.
Preferably, described dynamic model lower surface fixedly offers the locating slot corresponding with locating piece.
Preferably, described push rod is tubulose, for pushing-off product model.
Preferably, described cover half lateral surface fixedly offers cooling pipe.
Preferably, described cover half upper surface fixedly offers runner.
Distortion serious (circular arc is originally deformed into straight, does not have radian) after this mould completes, so employing is predeformation, is exactly die two ends are sliced off change mold insert specifically, has pulled certain angle, with former figure difference approximately about 4mm.The original radian required just in time is deformed to after shaping like this.
The beneficial effects of the utility model are, a kind of injection mold structure correcting the distortion of elongated plastic of the present utility model, optimizing moulding process by improving, mould being made to predeformation amendment, achieve plastic cement products one-shot forming, without the need to later stage adjustment, solve the problem of elongated plastic distortion.
