Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to a linkage injection mold. Background Technology

[0002] Injection molds are tools used to produce plastic products, giving them a complete structure and precise dimensions. Injection molding is a processing method used for the mass production of certain complex-shaped parts. Specifically, it involves injecting molten plastic into a mold cavity under high pressure using an injection molding machine, where it is then cooled and solidified to obtain the molded product.

[0003] Currently, injection molds mainly consist of an upper mold plate, a lower mold plate, inclined guide pillars, and a slider. The lower mold plate is located below the upper mold plate and its top surface has a groove and a sliding groove, with the sliding groove arranged from near to far from the groove. The slider slides within the sliding groove and has inclined guide holes on it. The top of the inclined guide pillar is fixed to the bottom of the upper mold plate and slides within the inclined guide holes, so that when the upper mold plate moves upward, it drives the slider away from the groove and detaches from the injection molded product. In other words, in traditional injection molds, driving the two sliders requires two sets of internal pulling structures, which not only increases the size of the injection mold but also raises the manufacturing cost and the difficulty of manufacturing the injection mold.

[0004] Therefore, how to design a simple, easy-to-operate, and interconnected double-slider injection mold is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] This invention provides a linkage injection mold that solves the technical problems of existing injection molds with double internal extraction structures, which increase structural size, raise manufacturing costs, and increase manufacturing difficulty.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a linkage injection mold, comprising: an upper mold plate, a lower mold plate, a spade base, a first slider, a slide block, and a second slider.

[0007] The top surface of the lower template is provided with a groove and a demolding slide, the demolding slide being arranged from near the groove to away from the groove; the top of the shovel base is fixed to the bottom surface of the upper template and its bottom end is fixed with an inclined guide post; the first slider slides in the demolding slide and is provided with an inclined guide hole; the inclined guide post slides in the inclined guide hole and pushes the first slider to slide away from the groove as the upper template moves upward; the slide block is fixed to the side end of the first slider corresponding to the groove and is provided with a limiting slide groove at the side end corresponding to the groove, the limiting slide groove being arranged inclined upward in sequence from away from the groove to near the groove; the first slider slides in the limiting slide groove so as to slide synchronously with the sliding of the first slider.

[0008] The beneficial effects of this utility model are: it improves the traditional double-pull structure of injection molds, uses the inclined guide post of the shovel base to drive the first slider to slide, and since the slide block is fixed on the first slider and has a limiting slide groove that is slidably connected to the second slider, the second slider can slide in conjunction with it, eliminating an inner pull structure, reducing the overall size of the injection mold, and reducing the difficulty of injection mold preparation and manufacturing cost.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, there are two second sliders that slide at intervals within the limiting groove.

[0011] Furthermore, the second slider has a connecting groove on its side end, and the side wall of the limiting groove extends towards the central axis to form a connecting strip, which slides within the connecting groove.

[0012] The further beneficial effect of adopting the above is that by using the connecting slider to slide within the connecting groove, the smoothness of the second slider sliding within the limiting groove can be improved.

[0013] Furthermore, the slide includes a first slide and a second slide, the first slide is fixed to the side end of the first slider corresponding to the groove; the bottom end of the second slide is fixed to the top end of the first slide; and the limiting groove is provided on the second slide.
