[0023] Cooling assembly 10 includes liquid storage tank 1001, the top of liquid storage tank 1001 is communicated with water pump 1002, the water outlet pipe of water pump 1002 is communicated with spray pipe 1004, the bottom of spray pipe 1004 is fixedly installed with support shaft 1003, the lower end of support shaft 1003 is connected with the top of base 3 through the vertical plate.

[0024] This technical solution, by installing a spray pipe 1004 on the right side of the lower die base 2, allows for the rapid and uniform spraying of the coolant inside the liquid storage tank 1001 onto the forging and the inner wall of the forging cavity within the lower die base 2 after forging by adjusting the spray angle of the spray pipe 1004. This provides rapid cooling of the forging, and the cooled liquid is discharged through a drainage groove on the front of the lower die base 2. The drainage groove is at the same level as the bottom of the forging cavity, which facilitates the smooth discharge of the liquid. When not in use, a sealing block 901 can be inserted into the drainage groove to seal it, without affecting the internal forging process. Example

[0025] Based on Embodiment 1, this utility model is as follows: Figure 2 As shown, the sealing assembly 9 includes a sealing block 901, a sealing plate 902 is fixedly installed at the front end of the sealing block 901, and a drainage groove is provided on the front of the lower mold base 2 to cooperate with the sealing block 901; the limiting assembly 8 includes a limiting spring 801, the upper end of the limiting spring 801 is welded to the bottom of the top plate 6, and the lower end of the limiting spring 801 is welded to the limiting plate 802.

[0026] Adopting such Figure 1 The technical solution shown is a component that directly cooperates with the drainage channel. Its shape and size are precisely matched with the drainage channel to achieve a good sealing effect. It is usually made of rubber or other materials with elasticity and sealing properties to ensure that it can fill gaps and prevent liquid leakage when in close contact with the drainage channel. The area of ​​the sealing plate 902 is usually larger than that of the sealing block 901, which can cover the opening edge of the drainage channel and further prevent liquid from seeping out from the edge. When the upper mold base 1 returns to its original position, the lower end of the limit spring 801 supports and squeezes the limit plate 802. The bottom of the limit plate 802 contacts the upper end of the guide plate 5 to play a limiting and buffering role.
