Injection mold with margin cutting function

Abstract

The invention discloses an injection mold with a margin cutting function. The injection mold comprises a left mold, a demolding cavity, a stripper plate, a right mold and an ejection plate. The demolding cavity is arranged inside the left mold. Equidistant demolding cylinders are arranged inside the demolding cavity. The stripper plate is arranged in the position, on one side of the demolding cylinders, of the interior of the demolding cavity. A pressing frame is arranged in the position, on one side of the demolding cavity, of the interior of the left mold. The right mold is arranged on one side of the left mold. A pressing tool is fixed to the outer wall of the side, close to the left mold, of the right mold. Buffering counter grooves are formed at the corners of the outer side of the pressing tool correspondingly. The outer walls of one sides of the right mold and the left mold are both provided with liquid injection grooves. A cutting structure is arranged in the position, on one side of a flow channel, of the interior of the right mold. The margin cutting function of the injection mold is achieved during injection molding, the demolding time of the injection mold is shortened,and the use convenience degree of the injection mold is improved.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to an injection mold with a margin cutting function. 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. [0003] At present, there are many types of injection molds, but there are still some problems. The specific problems are as follows: [0004] 1. Traditional injection molds of this type generally do not have a margin cutting function during injection molding, which seriously reduces the scope of use of injection molds; [0005] 2. Tradition...

AI Technical Summary

Problems solved by technology

[0004] 1. Traditional injection molds of this type generally do not have a margin cutting function during injection molding, which seriously reduces the scope of use of injection molds;

[0005] 2. Traditional injection molds of this type are more cumbersome when stripping, which greatly reduces the working efficiency of injection molds;

[0006] 3. Traditional injection molds of this type are generally not equipped with buffering and indicating functions during injection molding, which greatly affects the convenience of injection molds.
