Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation of injection molds, and particularly relates to an injection mold heat dissipation device. Background Art

[0002] During the manufacturing process of injection molds, heat dissipation devices play an important role. Since a large amount of heat is generated during the injection process, if the heat is not dissipated in time, it will cause the mold temperature to be too high, thereby affecting the product quality and production efficiency. The cooling water system is one of the most commonly used injection mold heat dissipation devices. By laying water pipes inside the mold and circulating cooling water to absorb heat, the mold temperature can be reduced. The cooling water can be supplied by an external cooling water machine or the factory's cooling water system. The fan cooling system accelerates the heat dissipation by forcibly air-cooling the mold. This kind of heat dissipation device is suitable for some smaller molds or situations that require rapid cooling.

[0003] The utility model with the publication number of CN206926216U discloses an injection mold heat dissipation device, which includes a flexible heat conduction belt passing through the upper mold and the lower mold of the injection mold. The flexible heat conduction belt is in a ring structure. One end of it located outside the injection mold is provided with a driving mechanism, and the other end is provided with a driven mechanism. The driving mechanism includes a motor, a rotating shaft, a fixed seat, a support plate, a driving roller and a heat dissipation fan blade. The driven mechanism is composed of a bottom plate, vertical rods arranged at both ends of the bottom plate and a driven roller arranged at the upper ends of the vertical rods. In the injection mold of the present utility model, a heat conduction belt capable of circular motion is arranged, and the heat of the injection mold is continuously exported by using the heat conduction belt, indirectly increasing the air-cooling and convection areas and improving the heat dissipation effect. While the motor drives the heat conduction belt through the rotating shaft, it also drives the heat dissipation fan to blow away the heated air nearby to ensure the heat dissipation effect.

[0004] During the use of this device, accelerating the air velocity flow may damage the unformed mold in the mold, affecting the product quality, and it can only blow away the hot air and cannot dissipate heat and cool down the mold. Summary of the Utility Model

[0005] To solve at least to some extent the above technical problems, the present utility model provides an injection mold heat dissipation device.
