[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1-3 A high heat dissipation stamping die is shown, comprising a platform 1, an inverted U-shaped frame 2 is fixedly arranged on the top of the platform 1, a lower die 3 is slidably arranged on the top of the platform 1, a stamping mechanism 4 is arranged on the inner side of the inverted U-shaped frame 2, a rapid cooling mechanism 5 is arranged on the bottom of the platform 1, and a sealing mechanism 6 is arranged on the outer side of the stamping mechanism 4.

[0024] like Figure 2 As shown, the stamping mechanism 4 includes a hydraulic cylinder 41 and an upper mold 42, wherein the hydraulic cylinder 41 is fixedly arranged on the top of the inverted U-shaped frame 2 and its output shaft slides through the inverted U-shaped frame 2 and extends to the bottom of the inverted U-shaped frame 2, and the upper mold 42 is fixedly arranged at the bottom end of the output shaft of the hydraulic cylinder 41 and is located directly above the lower mold 3. By setting the above structure, it is convenient to place the raw material on the top of the lower mold 3, and then the hydraulic cylinder 41 drives its output shaft to descend, thereby driving the upper mold 42 to descend, and when the upper mold 42 is in contact with the top of the lower mold 3, the stamping is completed.

[0025] like Figure 2 As shown, the sealing mechanism 6 includes a sealing cover 61, a limiting plate 62 and a sealing strip 63, wherein the sealing cover 61 is slidably sleeved on the outside of the output shaft of the hydraulic cylinder 41, the limiting plate 62 is fixedly sleeved on the outside of the output shaft of the hydraulic cylinder 41 and is located on the inside of the sealing cover 61, and the sealing strip 63 is adhesively bonded to the bottom of the limiting plate 62. By setting the above structure, the sealing strip 63 can cooperate with the platform 1 to form a cooling chamber for the upper mold 42 after it is fitted to the top of the platform 1.

[0026] like Figure 3As shown, the rapid cooling mechanism 5 includes a water tank 51, a refrigerator 52, a telescopic rod 53, a return spring 54, a water circulation channel 55 and an inlet and outlet water pipe 56, wherein the water tank 51 is fixedly arranged at the bottom of the platform 1, the refrigerator 52 is fixedly arranged inside the water tank 51, the telescopic rod 53 is fixedly arranged between the lower mold 3 and the water tank 51, the return spring 54 is sleeved on the outside of the telescopic rod 53 and fixedly connected between the lower mold 3 and the water tank 51, the water circulation channel 55 is arranged through the top of the platform 1 and is connected to the water tank 51, and the inlet and outlet water pipe 56 It is fixedly arranged at the bottom right side of the water tank 51, and a stop valve is arranged on the water inlet and outlet pipes 56. By arranging the above structure, after the stamping is completed, the upper mold 42 drives the lower mold 3 to continuously move downward on the inner side of the platform 1. During the downward movement of the lower mold 3, the telescopic rod 53 is shortened, and the reset spring 54 is compressed. When the lower mold 3 moves downward, the cooling water inside the water tank 51 is pressurized and enters the cooling chamber formed by the platform 1 and the sealing cover 61 through the water circulation channel 55, thereby cooling the upper mold 42, and the lower mold 3 is continuously cooled by the cooling water inside the water tank 51.

[0027] Working principle of this utility model:

[0028] During actual use, the raw material is placed on the top of the lower mold 3, and then the hydraulic cylinder 41 drives its output shaft to descend, thereby driving the upper mold 42 and the sealing cover 61 to descend synchronously. When the upper mold 42 fits with the top of the lower mold 3, the stamping is completed, and the sealing strip 63 fits with the top of the platform 1;

[0029] Subsequently, as the output shaft of the hydraulic cylinder 41 continues to extend, the upper mold 42 drives the lower mold 3 to continuously move downward inside the platform 1. During the downward movement of the lower mold 3, the telescopic rod 53 is shortened, and the return spring 54 is compressed. When the lower mold 3 moves downward, the cooling water inside the water tank 51 is pressurized and enters the cooling chamber formed by the platform 1 and the sealing cover 61 through the water circulation channel 55, thereby cooling the upper mold 42, and the lower mold 3 is continuously cooled by the cooling water inside the water tank 51.

[0030] When the subsequent hydraulic cylinder 41 drives its output shaft to shorten, the upper mold 42 gradually rises, and at the same time, the compressed reset spring 54 drives the lower mold 3 to move up and reset. At this time, the cooling water on the inside of the sealing cover 61 flows back to the inside of the water tank 51 through the water circulation channel 55. The subsequent hydraulic cylinder 41 drives the sealing cover 61 to rise synchronously through the limit plate 62, thereby causing the upper mold 42 and the sealing cover 61 to reset synchronously.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
