Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, and particularly relates to a rapid cooling mold for injection molding. Background Technique

[0002] An injection mold is a special manufacturing process for soft rubber by the cooperation of a moving mold and a fixed mold for punching. Its manufacturing process is complex, which is easy to cause damage to the moving mold and the fixed mold, increasing the cost and reducing the production efficiency. The mold is the core of an injection molding machine, and different products can be produced through different molds.

[0003] In the Chinese utility model patent application publication specification CN207224483U, an injection mold is disclosed, including a moving mold and a fixed mold. The moving mold is provided with a moving mold base, a moving mold clamping plate, a core, a positioning pin, a guide sleeve and a connecting block. A push rod is provided on the connecting block. The fixed mold is provided with a fixed mold base, a fixed mold clamping plate, a cavity, a positioning groove, a reset rod and a fixed bolt hole. The moving mold and the fixed mold are cooperatively connected. In this injection mold, the added positioning pin, through the positioning pin and the positioning groove, prevents the core from being damaged due to misalignment during injection molding of the moving mold and the fixed mold, reducing the cost and having great popularization value. However, this device cannot rapidly cool down, resulting in a slow forming speed of the injection molding raw material and affecting the production efficiency. For this reason, we propose a rapid cooling mold for injection molding. Content of the Utility Model
