[0023] When in use, after the stamping of the product is completed, the water pump 902 can be controlled to pump out the water in the water tank 901, and then the nozzle 903 disperses the water into smaller water mist to cool the product. Cooling by water can increase the cooling speed of the product. At the same time, the water can be dispersed by the nozzle 903, thereby reducing the water pressure and preventing the product from being deformed due to excessive pressure. After the product is cooled, the motor 801 can be controlled to rotate. The motor 801 drives the sliders 803 to approach each other through the screw 802. When the sliders 803 are close, the bottom ends of the connecting rods 804 are driven to approach each other, so that the top of the connecting rod 804 moves upward. At this time, the transmission plate 805 will also be synchronously lifted up, so that the push plate 806 pushes the product out of the lower mold 7. This device can make it more convenient for personnel to replace the mold by setting the transmission plate 805 and the push plate 806 in a plug-in form, thereby improving the applicability of the equipment. At the same time, it is more convenient for personnel to take the product by pushing the push plate 806, thereby improving work efficiency.

[0024] like Figure 3-4As shown, the lifting mechanism 8 includes a motor 801, a screw 802, a slider 803, a connecting rod 804, a transmission plate 805 and a push plate 806. The output end of the motor 801 is fixedly connected to one end of the screw 802. The slider 803 is provided with two symmetrical sliders, and the slider 803 is threadedly connected to the outer wall of the screw 802. One end of the connecting rod 804 is hinged to the top of the slider 803, and the other end of the connecting rod 804 is hinged to the bottom end of the transmission plate 805. The top of the transmission plate 805 is movable. Connected to the bottom end of the push plate 806, a through groove 11 is opened at the inner bottom end of the lower mold 7, and the push plate 806 is movably connected to the inside of the through groove 11, a limiting groove is opened at the bottom end of the lower mold 7, and the limiting groove is adapted to the limiting groove, the fixed end of the motor 801 is fixedly connected to the outer wall of the top plate 2, a card slot 12 is opened at the bottom end of the push plate 806, and the card slot 12 and the top end of the transmission plate 805 are mutually plugged, an installation groove is opened at the top end of the top plate 2, and the screw 802 is rotatably connected to the inside of the installation groove.

[0025] After the product is cooled, the motor 801 can be controlled to rotate. The motor 801 drives the sliders 803 to approach each other through the screw 802. When the sliders 803 approach each other, the bottom ends of the connecting rods 804 are driven to approach each other, so that the top ends of the connecting rods 804 move upward. At this time, the transmission plate 805 will also be synchronously lifted up, so that the push plate 806 can push the product out of the lower mold 7. This device can make it more convenient for personnel to replace the mold by setting the transmission plate 805 and the push plate 806 in a plug-in form, thereby improving the applicability of the equipment. At the same time, it is also more convenient for personnel to take the product out by pushing the push plate 806, thereby improving work efficiency.

[0026] like Figure 2 As shown, the cooling mechanism 9 includes a water tank 901, a water pump 902, a nozzle 903 and a support rod 904. The output end of the water tank 901 is fixedly connected to the input end of the water pump 902 through a pipeline, and the output end of the water pump 902 is fixedly connected to the input end of the nozzle 903 through a pipeline, the nozzle 903 is fixedly connected to the top end of the support rod 904, the bottom end of the support rod 904 is fixedly connected to the top end of the top plate 2, the water tank 901 is fixedly connected to the top end of the support frame 1, and the water pump 902 is fixedly connected to one side of the top plate 2.

[0027] After the stamping of the product is completed, the water pump 902 can be controlled to pump out the water in the water tank 901, and then the nozzle 903 can disperse the water into smaller water mist to cool the product. Cooling by water can increase the cooling speed of the product. At the same time, the water can be dispersed by the nozzle 903, thereby reducing the water pressure and preventing the product from being deformed due to excessive pressure.

[0028] Here’s how it works:

[0029] After the stamping of the product is completed, the water pump 902 can be controlled to pump out the water inside the water tank 901, and then the nozzle 903 will disperse the water into smaller water mist to cool the product. Cooling by water can increase the cooling speed of the product. After the product is cooled, the motor 801 can be controlled to rotate. The motor 801 drives the sliders 803 to approach each other through the screw 802. When the sliders 803 approach, they will drive the bottom ends of the connecting rods 804 to approach each other, so that the top of the connecting rod 804 moves upward. At this time, the transmission plate 805 will also be synchronously lifted up, so that the push plate 806 will push the product out of the lower mold 7. This device can make it more convenient for personnel to replace the mold by setting the transmission plate 805 and the push plate 806 in a plug-in form.
