Abstract

The invention provides a treatment method of high rib position deep groove injection molding. The treatment method comprises the following treatment steps: (a) a high rib position deep groove product needing injection molding is designed as a multisection structural rib position; and a male mold and a female mold formed through injection molding are designed as corresponding matching structures; (b) ABS750+16% talcum powder is adopted as a filling material; (c) the filling material is fed in the male mold and the female mold through a feeding screw rod of an injection molding machine for segmented high-speed filling to compact a melt with high pressure for pressure keeping; and (d) the cooling and the demolding are performed. The treatment method improves the fluidity of the filling material, reasonably allocates the structure of the mold, the injection molding temperature, the pressure and the speed, improves the injection molding quality of the high rib position deep groove product, greatly improves the common conditions of sink marks and uneven surfaces, increases the pass percent of the high rib position deep groove product from 45% to 92%, improves the production efficiency, and saves the production resource.

Description

technical field [0001] The invention belongs to the technical field of injection molding, and in particular relates to a treatment method for injection molding of high-reinforcement and deep grooves. Background technique [0002] Injection molding process refers to the process of making semi-finished parts of a certain shape from molten raw materials through operations such as pressurization, injection, cooling, and detachment. At present, the injection molding process of general products is relatively mature, but for products that require relatively irregular injection molding structures, there are still certain deficiencies in the processing technology, especially for the injection molding of products with high ribs and deep grooves, there are serious dents and smooth surfaces. Poor degree, low qualified rate of injection molding, low production efficiency, waste of resources, high production cost. Contents of the invention [0003] The purpose of the present invention ...
