Problems solved by technology

However, since there are four protrusions on the back of the product, in order to avoid the phenomenon of wall shrinkage on the front, the injection pressure is relatively high, but this will produce a "bright line" on the front of the product. The "bright line" and the shrinkage wall defect disappear at the same time, and the product is improved after analysis

Abstract

The invention relates to an injection molding piece. The injection molding piece comprises an arc-shaped main body (1), a transition part (2) and fixed pieces (3), wherein the head of the arc-shaped main body (1) is a bending surface; upper and lower fixed pieces (3) are arranged on the left side and the right side of the bending surface of the head of the arc-shaped main body (1); and the transition part (2) is arranged at the bottom of the arc-shaped main body (1). The injection molding piece has a smooth appearance, does not have injection molding defects, and can guarantee the appearance requirement of the products.

Description

technical field [0001] The invention belongs to the technical field of injection molded parts, in particular to an injection molded part. Background technique [0002] It is an injection molded appearance part, and no injection defects are allowed in terms of technical indicators. However, since there are four protrusions on the back of the product, in order to avoid the phenomenon of wall shrinkage on the front, the injection pressure is relatively high, but this will produce a "bright line" on the front of the product. The "bright line" and the shrinkage wall defect disappear at the same time, and the product is improved after analysis. Will image 3 The steps in the frame line are removed and changed to a gradual transition. After improvement, the front "bright line" disappears. Problem solved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an injection molded part, which can ensure the appearance requirem...
