Description

There is the automobile front door injection mold of 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 the flow channel of melt from the nozzle of injector to die cavity.In injection moulding process, plastic melt enters mold cavity through flow passage system and nozzle, runner and cast gate, and the quality of flow passage system design, has very important impact to the quality of moulding and productivity effect.Common flow passage system by sprue, runner, cast gate, cold slug well and die cavity five part form.

Traditional mould is when the demoulding because product mating surface is without gradient, 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 distance of mould is as follows: top is moveable punch, and below is the die that two die plate inserts form depression, and punch and die form the die cavity treating injection moulding.

Realizing in process of the present utility model, inventor finds that prior art at least exists following problem:

Owing to adding the plastic pellet of melting during cast, easily make injection molding cavity region be out of shape, 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, described in there is cooling device automobile front door injection mold comprise cope match-plate pattern, the lower bolster matched with described cope match-plate pattern, the punch insert being arranged at described cope match-plate pattern, be arranged at described lower bolster die plate insert, be arranged at the core rod assembly of described lower bolster, be arranged at the cooling device of described die plate insert;

Described core rod component bottom sidewall is provided with core rod draw-in groove;

Described cooling device comprises the groove of undulate and the groove in S shape, arranges some water holes in described groove.

Described cope match-plate pattern, described lower bolster are equipped with injection hole.

The beneficial effect that the technical scheme that the utility model embodiment provides is brought is:

By arranging core rod draw-in groove, fixed product, accelerating demoulding efficiency, saving product take-off time; By arranging cooling device at die plate insert, after plastic pouring is completed, cooling forming is moulding as early as possible, prevents injection molding cavity region to be out of shape.

Accompanying drawing explanation

In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 1 is the structural representation with the automobile front door injection mold of cooling device that the utility model embodiment provides.

Detailed description of the invention

For making the purpose of this utility model, technical scheme and advantage clearly, 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, see Fig. 1, described in there is cooling device automobile front door injection mold comprise cope match-plate pattern 1, the lower bolster 2 matched with cope match-plate pattern 1, the punch insert 3 being arranged at cope match-plate pattern 1, the die plate insert 4 being arranged at lower bolster 2, the core rod assembly 5 being arranged at lower bolster 2, the cooling device 6 that is arranged at die plate insert 3.

Particularly, cope match-plate pattern 1, lower bolster 2 are equipped with injection hole 10.

Particularly, core rod assembly 5 is arranged on lower bolster 2, and the sidewall bottom core rod assembly 5 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 the groove 62 in S shape, arranges some water holes 63 in groove 62.

By arranging the groove 61 of undulate and the groove 62 in S shape in the non-injection moulding die cavity forming region of die plate insert 3, in the groove 62 in S shape, arrange some water holes 63, to reach cooling, after making casting complete, cooling forming is moulding as early as possible, 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 arranging core rod draw-in groove, fixed product, accelerating demoulding efficiency, saving product take-off time; By arranging cooling device at die plate insert, after plastic pouring is completed, cooling forming is moulding as early as possible, prevents injection molding cavity region to be out of shape.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
