Description
Technical field
The utility model relates to a kind of injection mold with concealed pouring gate structure.
Background technology
Traditional gate design links together with product directly on product appearance surface, causes product appearance defectiveness after pruning.
Utility model content
The purpose of this utility model is to overcome the defect existed in prior art, provides a kind of injection mold with concealed pouring gate structure, ensures that product appearance is attractive in appearance.
For achieving the above object, the technical solution of the utility model there is provided a kind of injection mold with concealed pouring gate structure, comprise patrix and counterdie, formed product chamber is formed between described patrix and described counterdie, described formed product chamber is connected with sprue gate, the Slideslip that described formed product chamber is connected with described sprue gate is provided with the slide block that cast gate stub bar can be moved down, described slide block is positioned at the top at described sprue gate and parallels conflict with product outer side edges, described slide block and drive rod are fixedly connected, the top in described formed product chamber is provided with fixed dam, described drive rod slides mutually with described fixed dam and arranges.
As preferably, described drive rod is arranged with back-moving spring, described back-moving spring is between described formed product chamber and described fixed dam.
Advantage of the present utility model and beneficial effect are: after injection moulding, moved down by uncured cast gate stub bar, moved to below product appearance surface by slide block, thus play the effect of hiding cast gate stub bar, ensure product appearance quality.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Wherein: 1, formed product chamber; 2, cast gate stub bar; 3, slide block; 4, drive rod; 5, fixed dam; 6, back-moving spring.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, a kind of injection mold with concealed pouring gate structure, comprise patrix and counterdie, formed product chamber 1 is formed between described patrix and described counterdie, described formed product chamber 1 is connected with sprue gate, the Slideslip that described formed product chamber 1 is connected with described sprue gate is provided with the slide block 3 that cast gate stub bar 2 can be moved down, described slide block 3 is positioned at the top at described sprue gate and parallels conflict with product outer side edges, described slide block 3 is fixedly connected with drive rod 4, the top in described formed product chamber 1 is provided with fixed dam 5, described drive rod 4 slides with described fixed dam 5 phase and arranges, described drive rod 4 is arranged with back-moving spring 6, described back-moving spring 6 is between described formed product chamber 1 and described fixed dam 5.
Operation principle: after injection moulding, is moved down uncured cast gate stub bar by slide block 3, is moved to below product appearance surface, thus plays the effect of hiding cast gate stub bar 2, ensures product appearance quality.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
