The utility model discloses a kind of car door injection mold with cooling device, belong to injection molding apparatus field.Described injection mold comprises cope match-plate pattern, lower bolster, the punch insert that is arranged at described cope match-plate pattern matching with described cope match-plate pattern, the die plate insert that is arranged at described lower bolster; Described injection mold also comprise be arranged at described lower bolster core rod assembly, be arranged at the cooling device of described die plate insert.The utility model is by core rod draw-in groove is set, and fixed product, accelerates demoulding efficiency, saves product take-off time; By cooling device being set at die plate insert, plastic pouring is completed after as early as possible cooling forming be moulding, prevent injection molding cavity region distortion.

Description

A kind of car door injection mold with cooling device
Technical field
The utility model relates to injection molding apparatus field, particularly a kind of automobile front door injection mold with cooling device.
Background technology
Mould is modern industry, particularly the industrial requisite technological equipment such as automobile, radio, aviation, electrical equipment and electrical, instrument, instrument, commodity.The flow passage system of injection mold refers to that melt starts till the flow channel of die cavity from the nozzle of injector.In injection moulding process, plastic melt is that nozzle, runner and cast gate enter mold cavity through flow passage system, the quality of flow passage system design, and the quality on moulding and productivity effect have very important impact.Common flow passage system is made up of sprue, runner, cast gate, cold slug well and die cavity five parts.
Traditional mould is because product mating surface is without gradient in the time of the demoulding, and patrix has back-off or die cavity is darker etc. that factor easily causes product to follow patrix deviates from together, cause product breakage, and affects product take-off time, affects working (machining) efficiency, increases production cost.
Moulding adopts mould to carry out injection molding, and the structure of mould distance is as follows: top is punch movably, and below is that two die plate inserts form the dies that cave in, and punch and die formation are treated the die cavity of injection moulding.
Realizing in process of the present utility model, inventor finds that prior art at least exists following problem:
During due to cast, add the plastic pellet of melting, easily make the distortion of injection molding cavity region, be therefore necessary to accelerate cooling forming after casting complete.
Summary of the invention
In order to solve the problem of prior art, the utility model embodiment provides a kind of automobile front door injection mold with cooling device.Described technical scheme is as follows:
The utility model embodiment provides a kind of automobile front door injection mold with cooling device, and described injection mold comprises cope match-plate pattern, lower bolster, the punch insert that is arranged at described cope match-plate pattern matching with described cope match-plate pattern, the die plate insert that is arranged at described lower bolster; Described injection mold also comprise be arranged at described lower bolster core rod assembly, be arranged at the cooling device of described die plate insert.
Particularly, described cooling device comprises groove and groove, and some water holes are set in described groove.
Particularly, described groove undulate, described groove is S-shaped.
Particularly, described core rod assembly is arranged at described lower bolster, and the sidewall of described core rod assembly bottom is provided with core rod draw-in groove.
Particularly, on described cope match-plate pattern, described lower bolster, be equipped with injection hole.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is:
By core rod draw-in groove is set, fixed product, accelerates demoulding efficiency, saves product take-off time; By cooling device being set at die plate insert, plastic pouring is completed after as early as possible cooling forming be moulding, prevent injection molding cavity region distortion.
Brief description of the drawings
Fig. 1 is the structural representation of the injection mold that provides of the utility model embodiment.Wherein, 1-cope match-plate pattern, 2-lower bolster, 3-punch insert, 4-die plate insert, 5-core rod assembly, 50-core rod draw-in groove, 6-cooling device, 61-groove, 62-groove, 63-water hole, 10-injection hole.
Detailed description of the invention
Below in conjunction with accompanying drawing 1, the utility model is described in further detail:
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
The utility model embodiment provides a kind of automobile front door injection mold with cooling device, referring to Fig. 1, described injection mold comprises cope match-plate pattern 1, the lower bolster 2 matching with cope match-plate pattern 1, the punch insert 3 that is arranged at cope match-plate pattern 1, the die plate insert 4 that is arranged at lower bolster 2, the core rod assembly 5 that is arranged at lower bolster 2, the cooling device 6 that is arranged at die plate insert 3.
Particularly, on cope match-plate pattern 1, lower bolster 2, be equipped with injection hole 10.
Particularly, core rod assembly 5 is arranged on lower bolster 2, and the sidewall of core rod assembly 5 bottoms is provided with core rod draw-in groove 50.
Particularly, cooling device 6 is arranged on die plate insert 3, and cooling device 6 comprises the groove 61 of undulate and S-shaped groove 62, and S-shaped groove 62 is interior arranges some water holes 63.
Form the groove 261 of region division undulate and S-shaped groove 62 by the non-injection moulding die cavity at die plate insert 3, some water holes 63 are set S-shaped groove 62 is interior, to reach cooling, making after casting complete cooling forming is as early as possible moulding, prevent die, i.e. injection molding cavity region distortion.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is: by core rod draw-in groove is set, fixed product, accelerates demoulding efficiency, saves product take-off time; By cooling device being set at die plate insert, plastic pouring is completed after as early as possible cooling forming be moulding, prevent injection molding cavity region distortion.
