[0029] It is beneficial to cool down the lower mold, thereby increasing the cooling speed and work efficiency. Figure 4 As shown, the airflow heat dissipation device 2 includes a ventilation pipe 21, which is arranged at the lower end of the inner side of the lower mold 3. A threaded groove 27 is provided at one end of the ventilation pipe 21, and a threaded sleeve 25 is movably provided inside the threaded groove 27. An air filter plate 22 is fixedly provided inside the threaded sleeve 25, and a rotating block 26 is fixedly provided on one side of the threaded sleeve 25. A fan fixing groove 23 is provided at the other end of the ventilation pipe 21, and an exhaust fan 24 is movably provided inside the fan fixing groove 23. The ventilation pipe 21 is fixedly provided through the lower end of the inner side of the lower mold 3, so that temperature is conducted through the ventilation pipe 21. A threaded groove 27 is provided at one end of the ventilation pipe 21, and a threaded sleeve 25 is movably provided inside the threaded groove 27. Since the inner wall structure of the threaded groove 27 is consistent with the outer surface structure of the threaded sleeve 25, a threaded connection is performed, thereby achieving the effect of disassembly and installation. A rotating block 26 is fixedly provided on one side of the threaded sleeve 25. Therefore, when it needs to be installed, the threaded sleeve 25 is driven to rotate by rotating the rotating block 26. When disassembling, the threaded sleeve 25 is disengaged from the threaded groove 27 by rotating the rotating block 26 in the opposite direction, thereby achieving replacement or cleaning.

[0030] The specific implementation method is as follows: a wind flow heat dissipation device 2 is provided, a ventilation pipe 21 is fixedly provided through the inner lower end of the lower mold 3, so that temperature is conducted through the ventilation pipe 21, a threaded groove 27 is provided at one end of the ventilation pipe 21, and a threaded sleeve 25 is movably provided inside the threaded groove 27. Since the inner wall structure of the threaded groove 27 is consistent with the outer surface structure of the threaded sleeve 25, a threaded connection is performed to achieve the effect of disassembly and installation, a rotating block 26 is fixedly provided on one side of the threaded sleeve 25, so when installation is required, the threaded sleeve 25 is driven to rotate by rotating the rotating block 26, and when disassembly is performed, the threaded sleeve 25 is separated from the threaded groove 27 by rotating the rotating block 26 in the opposite direction, so as to achieve replacement or cleaning, an air filter plate 22 is fixedly provided on the inner side of the threaded sleeve 25 to avoid the problem of debris clogging the ventilation pipe 21, a fan fixing groove 23 is provided at the other end of the ventilation pipe 21, and an exhaust fan 24 is movably provided inside the fan fixing groove 23, and through the limiting effect of the fan fixing groove 23, Thereby, the position of the exhaust fan 24 is fixed, and the air is drawn by the exhaust fan 24 as a whole, so that the air enters the ventilation pipe 21, so that the temperature of the ventilation pipe 21 is cooled by the air flow, thereby achieving the effect of wind heat dissipation. The overall working process is pressed down by the upper mold 1. Because the lower end of the upper mold 1 is fixedly provided with a limiting column 5, the limiting column 5 is inserted into the slide groove 9 at the four corners of the lower mold 3, so as to achieve the effect of limited downward pressure. A processing groove 8 is provided at the upper end of the lower mold 3, and the automobile top frame is placed therein. Through the extrusion of the upper mold 1, a stamping effect is achieved.
