Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold heating device. Background Technology

[0002] When the mold is used for the first time or when it is restarted after a shutdown, the temperature of the mold is close to room temperature. However, compared to the high temperature of the molten metal, the temperature of the mold is very low. In order to prevent the molten metal from cooling and solidifying when it first enters the mold and affecting the quality of the casting, the mold core needs to be preheated before casting production begins, so that the temperature of the mold core is raised to the temperature required by the casting process.

[0003] Patent publication number CN220579135U discloses a mold heating device capable of simultaneously heating multiple molds at a uniform temperature. The device includes a base plate, copper coils, infrared thermometers, and a medium-frequency induction heating device. The copper coils are mounted on the base plate and connected to the medium-frequency induction heating device. Multiple infrared thermometers are also connected to the medium-frequency induction heating device. This design uses a medium-frequency induction heating device to heat multiple molds placed within the copper coils using an electromagnetic field, resulting in uniform temperature. The infrared thermometers monitor the mold temperature in real time, ensuring that the temperature of each mold remains within ±5℃, minimizing temperature fluctuations and reducing product defect rates.

[0004] However, the aforementioned patent does not include a structure for heat dissipation. When the mold is heated, the temperature of the mold is high, and the heating device contains a large amount of hot air. When the heating device is turned on, the hot air will escape outward. At this time, removing the mold can easily cause burns to the workers, and the mold needs to be handled manually, which reduces work efficiency. Utility Model Content
