As shown in Figure 1, existing a injecting products is the battery case a (also referred to as battery clamp) for placing multiple battery, this product forms many battery placing trough a1 arranged in length and breadth, during use, cylindrical battery is plugged in the battery placing trough being arranged on product, to position the position of each battery and by mutually isolated for these batteries.Owing to the shell wall a2 (" shell wall " mentioned here refers to the part between adjacent cell placing trough on battery case) of battery case product is relatively thick, after injection mo(u)lding, product shrinks uneven, causes that battery case is internal and produces shrinkage cavity phenomenon.

Utility model content

This utility model purpose is: for the deficiencies in the prior art, it is provided that a kind of battery case injection mould with feeding structure, to prevent battery placing trough on the battery case of molding from producing shrinkage cavity phenomenon, it is ensured that the Forming Quality of battery case product.

The technical solution of the utility model is: a kind of battery case injection mould with feeding structure, including the male die core matched and mother module core, the formed product chamber for forming battery shell that is collectively forming by described male die core and mother module core, described male die core and mother module core are inserted with some that the stretch into described formed product intracavity feeding pins being arranged in parallel, during injection mo(u)lding, described each feeding pin is located in described forming cavity in the shell wall of battery case.

This utility model, on the basis of technique scheme, also includes following preferred version:

Described mother module core is arranged in the surface of described male die core, and male die core and mother module core are provided with several vertically distribution and pin holes one to one, described each feeding pin is from top to bottom sequentially inserted into the described pin holes of described mother module core and common mode core, and makes the middle part of each feeding pin be arranged in described formed product intracavity.

The upper end of described each feeding pin is provided with needle cap, and the needle cap of each feeding pin is marked with different numeral numberings.

The utility model has the advantages that: this utility model is inserted with the many feeding pins stretching into formed product intracavity in male die core and mother module core, during injection mo(u)lding, in the shell wall that each feeding pin is located in forming cavity battery case, it is formed with multiple through hole so that be formed in the shell wall of battery case, these through holes reduce the wall thickness of product, guarantee that product injection mo(u)lding after-contraction is uniform, it is prevented that battery placing trough is internal produces shrinkage cavity phenomenon.

Detailed description of the invention

Below in conjunction with specific embodiment, such scheme is described further.Should be understood that these embodiments are an illustration for this utility model and are not limited to limit scope of the present utility model.The implementation condition adopted in embodiment can do further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in normal experiment.

Fig. 2 and Fig. 3 illustrates a this specific embodiment with feeding structure battery shell injection mold of this utility model.Identical with traditional injection moulding mould, this mould also includes the structures such as the male die core 1 that matches and mother module core 2, described the male die core forming cavity being collectively forming and the glue-feeder that is connected with described forming cavity with mother module core.During practical application, the plastic pellet that internal injection is melted from glue-feeder to forming cavity, plastic pellet forms product to be produced after solidifying.

The key improvements of the present embodiment is in that: be inserted with many that the stretch into described formed product intracavity feeding pins 3 being arranged in parallel in described male die core 1 and mother module core 2, during injection mo(u)lding, described each feeding pin 3 is located in the shell wall a2 of battery case a in described forming cavity, it is formed with multiple through hole a3 so that be formed in the shell wall a2 of battery case a, these through holes a3 reduces the wall thickness of battery case product, guarantee that product injection mo(u)lding after-contraction is uniform, prevent battery placing trough a1 internal generation shrinkage cavity phenomenon, such as Fig. 4.

Described feeding pin 3 is fine needle shape, and its radius is very little, so the aperture of the through hole a3 formed on the battery case product of molding in the diagram is also very little, battery case structural strength does not constitute impact substantially.And the upper end of each feeding pin 3 is provided with needle cap, the needle cap of each feeding pin 3 is marked with different numeral numberings.

In this example, concrete assembling mode between described each feeding pin 3 and male and female die is as follows: mother module core 2 is arranged in the surface of male die core 1, and male die core 1 and mother module core 2 are provided with several vertically distribution and pin holes 4 one to one, each feeding pin 3 is from top to bottom sequentially inserted into the pin holes 4 of mother module core 2 and common mode core 1, and makes the middle part of each feeding pin 3 be arranged in described formed product intracavity.

Its parts being labeled are not related to the technological improvement point of this patent in FIG, and these parts can adopt injection mold conventional structure, therefore be not described in detail here.

Certainly, above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow people will appreciate that content of the present utility model and to implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations done according to the spirit of this utility model main technical schemes or modification, all should be encompassed within protection domain of the present utility model.
