an injection molded structure

Abstract

The invention relates to an injection molding structure, which comprises a first part, a second part and a third part which are sequentially connected, the first part and the third part are respectively fixed on a set of mutually parallel sides of the second part, and the The sides are beveled. There is a mold cavity in the third part, including the first cavity and the second cavity; the bottom surfaces of the first cavity and the second cavity are connected with the bottom surface of the third part, and both of them are connected with the adjacent third part connected sideways. The positioning holes sequentially pass through the first part, the second part and the third part for fixing them on the mold. The first part is provided with a positioning blind hole, the upper end of which communicates with the top surface of the first part, and the lower end extends into the third part after passing through the second part. The invention is used for being installed on an injection mold for injection molding production, and can reduce the processing difficulty of products with compartments inside.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection molding structure. Background technique [0002] Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting the heated and melted plastic into the mold cavity under high pressure from the injection molding machine, and after cooling and solidifying, a molded product is obtained. [0003] For products with internal compartments, the general solution is to directly process the injection cavity and glue position on the mold core, but the structure of this mold core is complex and the processing cost is very high, especially the structure size of the product is small, the injection molding process The degree of deformation of the middle in...

Problems solved by technology

[0003] For products with internal compartments, the general solution is to directly process the injection cavity and glue position on the mold core, but the structure of this mold core is complex and the processing cost is very high, especially the structure size of the product is small, the injection molding process The degree of deformation of the middle injection molding cavity is relatively large, which has a great impact on the accuracy and quality of the product, especially the high frequency of repairs during the production process, which will easily lead to an increase in production costs and an extension of the delivery cycle
