Description

Technical Field

[0001] The utility model relates to the field of mold equipment, in particular to an active heat dissipation type injection mold. Background Art

[0002] Injection molding is also called injection molding, which is a molding method that combines injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automated operation, precise product size, easy product replacement, and the ability to form parts with complex shapes. The existing injection molds must be cooled after injection molding during the injection molding process before the injection molded parts can be formed. When the cooling of the injection molded parts is uneven, the injection molded parts will not be formed after demolding, resulting in damage to the injection molded parts and increasing the cost of waste of injection molded parts. Among them, the application number is "CN202121311830.8", a fast heat dissipation injection mold. The utility model is a combination of motor, fan blades, heat dissipation cover and injection mold body. The motor is used to drive the rotation of the fan blades to achieve the heat dissipation effect on the injection mold body, which effectively solves the problem of long molding time of injection molded parts. The heat dissipation method of the rotation of the fan blades speeds up the heat dissipation after injection molding, shortens the molding time of injection molded parts, speeds up the processing progress of injection molded parts, and improves the efficiency of injection molded parts processing. However, the injection mold still has certain shortcomings when in use: the use of air cooling to cool the injection mold still has the problem of low heat dissipation efficiency, and there is still room for improvement in cooling during large-scale injection molding processing. In addition, the lower mold lacks a limit, which makes it easy to offset when contacting with the upper mold, causing the problem of mold deformation after molding. Utility Model Content
