The structure and design method of the gate position of injection molded parts

Abstract

The structure of the gate position of the injection molded part is characterized in that the gate position of the injection molded part is a convex structure that protrudes outward, and the diameter of the convex structure gradually increases from the top to the bottom, and the wall body transitions smoothly without corners The hollow tubular shape of the injection molded part is located on the top of the raised structure. The purpose of the present invention is to solve the problem of low strength at the gate position of injection molded parts, provide a structure for the gate position of injection molded parts, improve the structural strength of the gate position of injection molded parts, and ensure that the structure at the gate position of injection molded parts is in the process of loading It is not easy to be deformed and damaged, improves the reliability of the injection molded parts, prolongs the service life of the injection molded parts, and effectively improves the fluidity of the fluid material at the gate position, and improves the injection molding process performance of the injection molded parts. The invention also provides a structural design method for the gate position of the injection molded part.

Description

technical field [0001] The invention relates to a structure and a design method of a gate position of an injection molded part, which are used for enhancing the bearing strength of the gate position of an injection molded part and improving the injection molding process performance of the injection molded part. Background technique [0002] In the field of lightweight applications, injection molding structures are often used instead of metal structures, but injection molding gates have low strength and are generally not suitable for excessive loads. However, in the actual structural design, under the comprehensive consideration of economy and formability, the gate positions of some injection molded structural parts need to bear relatively large loads, and even inevitably appear on the main force transmission path of the structure. [0003] The existing technologies for injection molding structure gates often improve the mold gates and improve the injection molding process, b...
