[0002] Automotive molds are essential process equipment used to form various metal parts during the automotive manufacturing process, playing a key role in vehicle quality, production efficiency, and cost control. Existing automotive molds typically consist of fixed and movable molds, which are used to create or remove parts through various operations. With the rapid development of the automotive industry, the requirements for production efficiency and quality of automotive molds are becoming increasingly stringent, leading to the emergence of rapid cooling devices.

[0003] Chinese patent CN214949984U discloses a rapid cooling device for automobile metal mold production. Through a curved cooling pipe set on the fixed mold base, a water pump can be used to transport cooling water from the cooling box to the cooling pipe. During the rapid flow of cooling water, the heat inside the mold is taken away, thereby achieving the purpose of rapid cooling.
