Heat-dissipating and cooling device of injection mould

Abstract

The invention discloses a heat-dissipating and cooling device of an injection mould. The heat-dissipating and cooling device comprises a radiator which is arranged at the lower end of a fixed mould inthe injection mould, wherein the upper end in the radiator is equipped with a water-cooling box; one end of the water-cooling box communicates with a water inlet tube through a connecting tube base;the other end of the water-cooling box communicates with a water outlet tube through a connecting tube base; a controlled-flow piston is arranged on the water outlet tube; a rotary impeller inside thewater inlet tube is mechanically connected with a connecting gear group; the connecting gear group is connected with a drive worm at the lower end of a fan; the controlled-flow piston comprises a piston arranged in the water outlet tube; the lower end of the piston is connected with a threaded rod; the lower end of the threaded rod is connected with a motor output end; and a threaded sleeve blockwhich is fixedly connected with the tube wall of the water outlet tube is in threaded sleeve connection on the threaded rod. According to the heat-dissipating and cooling device disclosed by the invention, quick radiating is performed by the radiator, and production efficiency also can be improved while cooling speed is increased, so that the product deformation problem caused by continuous shrinking after de-molding is avoided.

Description

technical field [0001] The invention relates to a heat radiation cooling device for an injection mold, which belongs to the field of heat radiation cooling devices. Background technique [0002] Injection molding is a tool for producing plastic products, and it is also a tool for giving plastic products a 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 melting plastic by heat. The injection molding machine injects into the mold cavity under high pressure, and after cooling and solidifying, the 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 closed to form the gating system ...
