Efficient injection mold

Abstract

The invention relates to the technical field of injection molds, in particular to an efficient injection mold. Injection molding cavities are formed in the upper parts and the lower parts of the surfaces, close to each other, of the two molds; a bracket; the support is located on the sides, away from each other, of the two molds. A rotating shaft; the rotating shaft is rotationally connected with the upper part of the bracket, and one end of the rotating shaft is fixedly connected with the center of the mold; a slide bar; the sliding rod is connected with the two supports in a sliding mode. The axial lead direction of the sliding rod is consistent with the mold closing direction; a cooling hole; the cooling holes are formed in the mold and are symmetrically arranged relative to the center of the mold; a water outlet and a water inlet of the cooling hole are formed in the outer wall of the mold; according to the invention, one part of the mold is subjected to injection molding, and the other part of the mold is preheated synchronously, so that the time of waiting for preheating of the mold by a worker is shortened, and seamless connection of injection molding of the mold by the worker is realized; and the injection molding efficiency of the mold is greatly improved.

Description

technical field [0001] The invention relates to the technical field of injection moulds, in particular to an efficient injection mould. Background technique [0002] Injection mold is a tool for producing plastic products; 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 some complex-shaped parts. Due to the large amount of injection molds used and the different fields of application, the classification is complicated. According to the molding characteristics, it can be divided into thermosetting injection molds and thermoplastic injection molds. According to the molding process, it can be divided into transfer molds, blow molds, casting molds, thermoforming molds, hot pressing molds and injection molds. [0003] The injection molding process is generally as follows: first, the raw materials are heated to the melting point and then melted, and then the mold is c...

Problems solved by technology

[0003] The process of injection molding is generally as follows: first, heat the raw material to the melting point and melt it, then close the mold, and then preheat the injection mold. The purpose of mold preheating is to prevent the occurrence of sticking to the mold, and also to speed up product molding. , After the mold is preheated, the raw material in the molten state is extruded into the mold through the screw extruder, and finally the mold is cooled and formed by the cooling liquid. Preheat and repeat the above steps; it can be seen that the mold needs to be preheated every time the injection is re-injected, which takes a lot of time, so the efficiency of injection molding
