Problems solved by technology

When molding, the soft rubber 12 has not completely cooled down, and the moment the mold is opened, the material head will pull the soft rubber 12 into a depression, thus affecting the appearance of the product 10, and thus failing to achieve the expected effect
[0003] In view of this, it is necessary to provide a structure that prevents the appearance of the soft rubber from being dented, so as to solve the above-mentioned phenomenon that the soft rubber is dented due to the large amount of deformation of the soft rubber

Abstract

A structure for preventing soft plastic appearance from being pulled to be sunken is applied to a forming overmold product, and the inner side of the product is a non-appearance surface. The structure for preventing the soft plastic appearance from being pulled to be sunken comprises hard plastic and soft plastic, wherein the hard plastic comprises a hard plastic body and a plurality of flash grooves formed from the hard plastic body surface to the hard plastic body, the flash grooves are positioned in the non-appearance surface at the inner side of the product, the soft plastic comprises a soft plastic body and an extension part protruding from the soft plastic body surface, the soft plastic body surface is in contact with the hard plastic body surface, the extension part is inserted into the flash grooves in a matched way, the flash grooves are positioned on the non-appearance surface at the inner side of the product, and a soft plastic inlet point is positioned at the lower end of the extension part. The structure for preventing the soft plastic appearance from being pulled to be sunken, disclosed by the invention, is applicable for a non-appearance part at the inner side of the product, is simple and is convenient to process, and product appearance can be better prevented from being pulled to be sunken.

Description

【Technical field】 [0001] The invention relates to an injection molding structure, in particular to a structure for preventing the appearance of soft rubber from being depressed. 【Background technique】 [0002] The secondary injection molding of soft rubber (generally refers to thermoplastic elastomer) and hard rubber (generally refers to thermoplastic) can not only make the surface of some products full of softness, but also increase the appearance, functionality and added value of the product. see figure 1 and figure 2 As shown, the product 10 includes hard glue 11 and soft glue 12 formed on the hard glue 11. Generally, the glue inlet points 13 of the soft glue 12 are all placed directly below the soft glue 12. Since the glue is fed by horns, the glue inlet points and When the product 10 falls off, there will be mutual pulling force, especially for thermoplastic elastomers, the larger the deformation, the greater the pulling force. When forming, the soft rubber 12 has n...
