Slide block plastic injection structure

Abstract

The invention provides a slide block plastic injection structure which is applied to a mold and takes the mold-opening direction of the mold as a vertical direction. The slide block plastic injectionstructure comprises slide blocks, which are arranged on the outer side of a to-be-molded product; vertical runners, with one ends connected with the hot sprues of the mold and the other ends vertically penetrating the slide blocks; transverse runners, which are horizontally arranged on the bottom sides of the slide blocks and communicate with the other ends of the vertical runners; and branch runners, which are diverted from the transverse runners and vertically and upwardly bend from the horizontal direction to form plastic injection ports for plastic injection. According to the slide block plastic injection structure in the invention, the vertical runners are configured to penetrate the slide blocks for plastic injection, and plastic injection ports can be additionally formed in the middle parts of the length or width direction of the product, so the problem that extra plastic injection ports cannot be formed in the middle parts of the length or width direction of products due to shielding of the products by slide blocks in the prior art is overcome.

Description

【Technical field】 [0001] The invention relates to a mold structure, in particular to a sliding block glue feeding structure. 【Background technique】 [0002] When injecting plastic products, if the product is in the shape of a cuboid, such as a laptop case, etc., the glue is usually injected from the four corners of the product. [0003] However, see figure 1 , which depicts a schematic diagram of a product. If the length or width of the product 10 is relatively long, the effect of glue feeding from the four corners is not good, and it is necessary to add glue inlets in the middle of the length or width. Usually, there is a slider on the outside of the product 10, and the slider will block the product 10, so it is impossible to increase the glue inlet from the middle of the length or width of the product 10, and then the product 10 cannot be formed. [0004] In view of this, it is necessary to develop a slider glue feeding structure to solve the problem that the slider wil...

Problems solved by technology

Usually there is a slider on the outside of the product 10, the slider will block the product 10, and it is impossible to increase the glue inlet from the middle of the length or width of the product 10, and thus the product 10 cannot be formed.

[0004] In view of this, it is necessary to develop a slider glue feeding structure to solve the above problem that the slider will block the product and the glue inlet cannot be added from the middle of the product
