Problems solved by technology

After the metal part 10 is placed in the mold, the plastic part 12 is injection molded, and after the injection molding of the plastic part 12 is completed, due to the existence of the barb 14, the product 10 cannot be demoulded normally
[0006] In view of this, it is necessary to develop an undercut forming structure and a forming method of the product to solve the above-mentioned problem that the product cannot be demolded normally due to the existence of the undercut

Abstract

The invention relates to an injection molding mould structure, in particular to an inverted hook formation structure and formation method of a product. The inverted hook formation structure of the product comprises two plugs, wherein the two plugs are arranged on a metal piece, are oppositely arranged and are mutually connected with each other; the inner walls of the combined two plugs are matchedwith a cylindrical shaped structure of a plastic plastic rubber piece; and a glue inlet hole is formed in the tops of the two plugs and communicates with a glue inlet flowing channel of a mould. According to the inverted hook formation structure and formation method of the product disclosed by the invention, the product can be normally demoulded, and demoulding of the product cannot be affected because of an inverted hook.

Description

[0001] 【Technical field】 [0002] The invention relates to an injection mold structure, in particular to an undercut forming structure and a forming method of a product. [0003] 【Background technique】 [0004] Due to the rise of the automobile industry, more and more magnesium parts are overmolded, that is, the product is a combination of metal parts and plastic parts. When molding such products, it is necessary to embed metal parts into the injection mold first, that is, the metal parts are inserts, and then injection mold plastic parts on the metal parts. [0005] see figure 1 , which depicts a schematic diagram of a product. The product 10 is a combination of a metal part 11 and a plastic part 12 , and the plastic part 12 of the product 10 has a cylindrical structure 13 , and the outer ring of the cylindrical structure 13 is provided with a barb 14 . After the metal part 10 is placed in the mold, the plastic part 12 is injection molded, and after the injection molding of...
