AI Technical Summary

Technical Problem

During the injection molding process of plastic front center grille, the first snap and second molding block after forming form an inverted structure, making it difficult for the front center grille body to be removed smoothly.

Method used

An injection molding mold is designed to remove the inverted structure of the first snap and the second molding block when the front center body is unmolded through the ejection action of the oblique lever. The mold includes a moving template, a sliding groove, an oblique top rod, a first forming block and a second forming block. By controlling the movement of the first and second top plates, the ejection action of the oblique top rod is realized, and the forming block is driven away from the snap structure.

Benefits of technology

It effectively solves the problem of snapping and buckle structure of the front center body during the demolding process, ensures that the front center body can be demolded smoothly, reduces the post-maintenance cost of the mold, and simplifies the replacement process of the second molding block.

Abstract

The utility model relates to a plastic front middle net injection molding mould, including an upper mould body and a lower mould body, the lower mould body includes a lower fixed plate, a first top plate, a second top plate, two mould feet and a movable mould plate, the movable mould plate is provided with a mould core for molding a front middle net body, and one side of the movable mould plate facing the lower fixed plate is provided with a plurality of chutes communicated with the mould core. The multiple sliding grooves are internally connected with angle ejector rods in a sliding mode, the second ejector plate is connected with multiple angle ejector sliding bases in a sliding mode, the bottom ends of the multiple angle ejector rods are connected with the multiple angle ejector sliding bases correspondingly, and the multiple angle ejector rods are provided with first forming blocks. First forming cavities used for forming first buckles are formed between the first forming blocks and the sliding grooves, and second forming blocks used for forming first assembly holes are arranged on the multiple first forming blocks. When the front middle net body is demolded, the inverted buckle structure of the first buckle and the second forming block is removed, so that the front middle net body can be demolded smoothly.
