Description

Technical Field

[0001] The utility model relates to the field of injection molds, in particular to a stable injection mold. Background Art

[0002] An injection mold is a tool used to produce plastic products. It is also a tool that gives plastic products a complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain parts with complex shapes. Specifically, it refers to the process of injecting heated and molten plastic into the mold cavity under high pressure by an injection molding machine. After cooling and solidification, the molded product is obtained.

[0003] Currently, a Chinese patent with the announcement number CN213830168U discloses a stable injection mold, including a base, wherein the upper right rear portion and the upper left rear portion of the base are fixedly connected to fixed plates, the upper rear portion of the base is fixedly connected to a fixed template, and the fixed template is located between the two fixed plates, and the upper front portion of the base is fixedly installed with a vertical plate, and the upper portion of the rear end of the vertical plate is fixedly connected to a telescopic controller. However, the above patent has a poor clamping effect on the fixed template by two clamping plates. After the fixed template is subjected to the impact force when the movable template is closed, it is easy to shake, which in turn affects the stability of the mold during injection molding. Therefore, we propose a stable injection mold to solve the above problem. Utility Model Content
