Injection mold with insert assembling structure

Abstract

An injection mold with an insert assembling structure includes a fixed mold (1) and a movable mold (2), and is characterized in that the fixed mold (1) is provided with a first inclined guide pillar (11) and a second inclined guide pillar (12), and the first inclined guide pillar (11) and the second inclined guide pillar (12) are arranged in a splayed shape; the movable mold (2) is provided with a guide sliding chute (3), and first sliding blocks (21) and second sliding blocks (22) are arranged in the guide sliding chute; the first sliding blocks (21) are each provided with a side drawing core (23) and a first through hole, the side drawing cores (23) are used for assembling inserts (4), and the first through hole is matched with the first inclined guide pillar (11); the second sliding blocks (22) are each provided with a movable mold core (24) and a second through hole, the movable mold cores (24) are matched with the side drawing cores (23), and the second through hole is matched with the second inclined guide pillar. The injection mold solves the problems that a conventional injection mold with an insert assembling structure has complex structure and easily produces insert coverage, and improves the production efficiency and the product qualification rate.

Description

technical field [0001] The invention belongs to the field of injection molds, in particular to an injection mold with an insert structure. Background technique [0002] Due to technical problems, the existing products cannot realize the molding of insert pins and plastic parts together, and the pins need to be assembled in a follow-up process. Since the pins are inserted later, the length of the pins is not uniform, and the pins are easy to fall off. Such as various types of automotive electrical switches, as shown in the accompanying drawings figure 1 shows the structure of plastic parts with metal inserts and metal inserts. Because the inserts are relatively thin and easy to deform, installation is difficult, and defects such as insert scrapping and insert covering are prone to occur. [0003] For example, Chinese patent application number 201120242447.1 discloses an insert assembly device for an injection mold, which is assembled on the inner and rear molds of the lower...
