[0013] Compared with the prior art, this utility model provides a cooling device for the production of automobile roof molds, which has the following beneficial effects:

[0014] The cooling device used in the production of the car roof mold involves activating a fan, a cooler, and a stepper motor. The fan supplies air to the cooler via a connecting pipe. After being cooled by the cooler, the air enters the interior of the housing via a first air supply pipe. A portion of the cooled air then enters the cavity via a second air supply pipe, thereby cooling the bottom wall of the fixed mold groove through heat transfer, thus cooling the bottom area of ​​the finished car roof. Another portion of the cooled air from the housing enters the nozzle via a third air supply pipe and is then sprayed downwards from the nozzle. Simultaneously, the stepper motor... This drives the worm gear to rotate, which in turn drives the mounting shaft and disc to rotate via the worm wheel. This, in turn, causes the lever to rotate. As the lever rotates, it compresses the left and right sides of the inner wall of the traction frame, causing the traction frame, moving block, and air nozzle to move back and forth to the left and right. As the air nozzle moves back and forth, it sprays cold air onto the top of the finished car roof, thus cooling the top area of ​​the finished car roof. By simultaneously cooling the bottom and top of the finished car roof, the cooling effect and efficiency are improved, making it more convenient for users. Attached Figure Description

[0025] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Therefore, this utility model will not explain the control method and circuit connection in detail.

[0026] During use, two hydraulic cylinders 7 can be activated to move the die head 6 downwards to perform the stamping and forming of the car roof. After forming, the two hydraulic cylinders 7 can be activated to move the die head 6 upwards to reset it. When it is necessary to cool down the finished car roof in the fixed mold groove 8, the fan 102, cooler 101 and stepper motor 251 can be activated. The fan 102 will supply air to the cooler 101 through the connecting pipe 103. After being cooled by the cooler 101, the air will enter the interior of the box 9 through the first air supply pipe 104. Part of the cold air will enter the interior of the cavity 11 through the second air supply pipe 12, thereby cooling the bottom wall of the fixed mold groove 8 through heat transfer, thus cooling the bottom area of ​​the finished car roof. The other part of the cold air in the box 9 will enter the cavity 11 through the third air supply pipe 12. 7 enters the interior of the jet nozzle 15 and is then ejected downwards from the jet nozzle 15. At the same time, the stepper motor 251 drives the worm gear 253 to rotate, which in turn drives the mounting shaft 19 and the disc 20 to rotate through the worm wheel 254. This drives the lever 21 to rotate. When the lever 21 rotates, it squeezes the left and right sides of the inner wall of the traction frame 24, thereby driving the traction frame 24, the moving block 14, and the jet nozzle 15 to move back and forth to the left and right. When the jet nozzle 15 moves back and forth, it sprays cold air onto the top of the finished car roof, thereby cooling the top area of ​​the finished car roof. By cooling the bottom and top of the finished car roof at the same time, the cooling effect and efficiency are improved, which facilitates the use of the user. After cooling is completed, the finished car roof can be taken out from the interior of the fixed mold slot 8.

[0027] In summary, the cooling device for producing the car roof mold works by activating the fan 102, cooler 101, and stepper motor 251. The fan 102 supplies air to the cooler 101 via the connecting pipe 103. After being cooled by the cooler 101, the air enters the interior of the housing 9 via the first air supply pipe 104. A portion of the cooled air enters the interior of the cavity 11 via the second air supply pipe 12, thereby cooling the inner bottom wall of the fixed mold groove 8 through heat transfer, thus cooling the bottom area of ​​the finished car roof. Another portion of the cooled air in the housing 9 enters the interior of the nozzle 15 via the third air supply pipe 17, and is then sprayed downwards from the nozzle 15. Simultaneously, the stepper motor 251 drives the worm gear 253 to rotate, which in turn drives the mounting shaft 19 and the worm wheel 254 to rotate. The disc 20 rotates, which in turn drives the lever 21 to rotate. When the lever 21 rotates, it presses against the left and right sides of the inner wall of the traction frame 24, thereby causing the traction frame 24, the moving block 14, and the jet nozzle 15 to move back and forth to the left and right. When the jet nozzle 15 moves back and forth, it sprays cold air onto the top of the finished car roof, thereby cooling the top area of ​​the finished car roof. By cooling both the bottom and top of the finished car roof at the same time, the cooling effect and efficiency are improved, which makes it more convenient for users. This solves the problem that existing cooling devices are mostly simple in their cooling methods, usually only cooling the bottom of the finished car roof, resulting in poor heat dissipation and low efficiency, which is not conducive to use.
