Problems solved by technology
Each small body 12 needs a glue inlet to be formed, and the distance between the glue inlet and the glue inlet is very small. The ordinary three-plate mold has no space for densely arranged glue inlets, which is prone to interference
[0004] In view of this, it is necessary to develop a multi-point glue inlet structure to solve the problem that there is no space to arrange dense glue inlets in the prior art

Embodiment Construction
[0029] In order to have a further understanding of the purpose, technical effect and technical means of the present invention, the detailed description is as follows in conjunction with the accompanying drawings.
[0030] see figure 2 As shown, it shows a three-dimensional schematic view of the multi-point glue-injecting structure of the present invention. A multi-point glue feeding structure of the present invention is applied to a mold, the mold includes a male mold core 21 and a female mold core 22, and the male mold core 21 and the female mold core 22 form a cavity-molded product 10. In an embodiment, the multi-point glue-feeding structure includes:
[0031] Main channel 100, which is connected with the nozzle of the injection machine;
[0032] The runner 200 is located on the female die core 22 and communicates with the main runner 100, please refer to image 3 and Figure 4 As shown, the female mold core 22 is provided with a groove 221, specifically the groove 221 ...

The invention relates to the technical field of injection molds, in particular to a multi-point glue feeding structure. A multi-point glue feeding structure is applied to a mold, the mold comprises a male mold core and a female mold core, the male mold core and the female mold core form a cavity forming product, and the multi-point glue feeding structure comprises a main runner, a plurality of glue feeding holes and a plurality of glue feeding holes, the sub-runner is arranged on the female mold core and communicated with the main runner, a groove is formed in the female mold core, and the sub-runner is arranged along the bottom wall of the groove; and the glue inlet is respectively communicated with the sub-runner and the cavity, and the glue inlet extends from the bottom wall of the groove to the direction of the core insert. According to the multi-point glue feeding structure disclosed by the invention, the groove is formed in the back surface of the cavity insert, the sub-runner is formed in the bottom wall of the groove, and the glue is fed into the cavity through the glue inlet extending downwards along the bottom wall of the groove, so that the problem of interference caused by dense glue feeding points is solved, and meanwhile, the weight of a material head is greatly reduced; and the device is suitable for producing molds needing multi-point glue feeding and multi-cavity products.
Description
【Technical field】 [0001] The invention relates to the technical field of injection molds, in particular to a multi-point glue feeding structure. 【Background technique】 [0002] In the injection mold, the runner system is the necessary channel for the molten plastic to pass through from the nozzle of the injection machine to the cavity. The runner system includes the main runner, the runner and the glue inlet (also known as the gate or the feed inlet). [0003] When producing plastic products, please refer to figure 1 as shown, figure 1 A schematic diagram of a product is shown in . The product 10 is a keyboard, and the product 10 is composed of a main plate 11 and several small bodies 12, and the number of the small bodies 12 is more than 400. Each small body 12 needs a glue inlet to form, and the distance between the glue inlet and the glue inlet is very small. The common three-plate mold mold has no space for densely arranged glue inlets, which is prone to interference...
