Demoulding structure of injection molding mould

Abstract

The invention discloses a demoulding structure of an injection molding mold, which includes a mold fixing frame. A telescopic cylinder is fixed on one side of the mold fixing frame through the cylinder fixing frame, and the telescopic cylinder is released from the inside of the mold fixing frame through a telescopic rod. The mold base is welded, and the center of the housing on the other side of the mold fixing frame is screwed with a mold bin through a fixed stud. An injection port is provided, and a demoulding rod is embedded and fixed on the demoulding frame through a fixing nut. In the present invention, firstly, by providing a telescopic cylinder and two demoulding rods, the telescopic cylinder can be used to control the demolding rods to expand and contract, thereby realizing automatic demoulding, which improves the working efficiency, and the two demoulding rods are up and down symmetrically. Demoulding, so that the mold is evenly stressed, and prevents the mold from being deformed by force due to the incomplete cooling of the mold, thereby affecting the appearance and precision of the product.

Description

technical field [0001] The invention relates to the technical field of injection molding molds, in particular to a demoulding structure of an injection molding mold. 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 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, the molded product is obtained. The injection mold is divided into thermosetting plastic mold and thermoplastic plastic mold according to the molding characteristics; according to the molding process, it is divided into transfer mold. , blow molding mold, casting mold, thermoforming mold, hot pressing mold (compression molding mold), injection mold, etc. Among th...

Problems solved by technology

[0003] The demoulding structure of the injection molding mold is a structure used for demoulding on the injection mold. The demoulding structure of the transmission injection molding mold is relatively simple, and the demoulding operation is not convenient enough. At the same time, it is easy to affect the shape and appearance of the product, thus lead to lower product quality
