Environment-friendly plastic injection mold

Abstract

The invention discloses an environment-friendly plastic injection mold, and belongs to the field of injection molds. The environment-friendly plastic injection mold is characterized in that through the arrangement of a thermal ball chain, when a molten material is injected, the temperature rises, and air in thermal collision balls is heated to expand, so that the distance between every two adjacent thermal collision balls on the thermal ball chain is reduced; and through cooperation with self-hardening bags, repulsive force exists between every two adjacent thermal collision balls, the thermalcollision balls which are close to each other are in an unstable state, the thermal collision balls continuously move in a self-vibration cavity, and the moving degree of the thermal collision ballsis increased when the thermal collision balls expand increasingly along with continuous injection of molten material, the thermal collision balls collide with the inner wall of the self-vibration cavity, therefore, the thermal ball chain generates a vibration effect on the injected molten material, the number of bubbles in the molten material is remarkably reduced, the quality and strength of a finished product are higher, the situation of local cracking or breaking during use is effectively avoided, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to an environment-friendly plastic injection mold. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die casting method. Injection molding machine (referred to as injection machine or injection molding machine) is the main molding equipment for making thermoplastic or thermosetting materials into various shapes of plastic products using plastic molding molds. Injection molding is realized through injection molding machines and molds. Injection molding is mainly divided into the following three categories: [0003] 1. Rubber injection molding: Rubber injection molding is a production method in which rubber is injected directly from the barrel into the model for vulcanization...

AI Technical Summary

Problems solved by technology

[0006] During the injection molding process of the injection mold, the injection molding material is generally in a molten state. When the molten material is injected into the mold cavity, the air in the cavity will be partially mixed into the molten material, so that the plastic product contains voids inside, making the finished product Low hardness, poor quality, prone to local cracking or even breaking when in use
