Vacuumizing assisted double-color injection moulding device

Abstract

The invention discloses a vacuumizing assisted double-color injection moulding device which comprises an injection moulding machine, a two-color encapsulation machine and a vacuumizing machine, wherein a mould is arranged on the injection moulding machine; the mould comprises a front mould and a rear mould; the front mould and the rear mould cooperate to form a mould cavity for injection moulding;a nozzle is arranged on the injection moulding machine; a main sprue connected with the nozzle of the injection moulding machine is formed in the front mould; the main sprue is connected with a runner; the runner is connected with the mould cavity through the sprue; a first-color raw material is injected into the mould cavity through the nozzle of the injection moulding machine to form a one-color product; the rear mould of the mould rotates; a nozzle is formed on one side of a two-color encapsulation machine; a two-color sprue bush connected with the nozzle of the two-color encapsulation machine is arranged on the front mould; a main sprue connected with the nozzle of the two-color encapsulation machine is formed in the mould. When the device is put into use, the capacity and yield are greatly improved, a full-automatic way is realized, and an aim of reducing the human and material cost is achieved; thus the device is suitable for industrial popularization.

Description

technical field [0001] The invention relates to the technical field of mold injection molding production, and more specifically relates to a vacuum-assisted two-color injection molding device. Background technique [0002] Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting the heated and melted plastic into the mold cavity under high pressure from the injection molding machine, and after cooling and solidifying, a molded product is obtained. The injection mold consists of a moving mold and a fixed mold. The moving mold is installed on the movable template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the movable mold and the fixed mold are...

Problems solved by technology

[0003] Ordinary two-color injection molding process generally uses parallel twin-screw or vertical 90-degree two-color injection molding equipment for production, that is, after the first-color product is produced, it is put into the second-color mold to produce the rubber-coated product. Put the first color product into the second color mold, injection of soft glue will cause many problems with the appearance of the product, and the process is difficult to adjust, resulting in peeling, degumming, air bubbles, lack of glue, shrinkage, and flow marks on the appearance of the product , and other issues, the existing semi-automatic production wastes 50% of manpower, 20% of raw materials, 50% of water and electricity costs, 50% of packaging materials, 50% of storage locations temporarily used, and a defect rate of 30%.
