[0002] For some high-end models of LCD TVs, part or all of the TV shell will be manufactured by a stamping process; this process is to drive the upper die and the lower die to close by a press, complete the die closing of the stamping die, and then apply pressure to the raw material in the lower die to make it plastically deform along a predetermined trajectory, so as to form the required shape of the TV shell. After the TV shell is stamped and formed, the upper die and the lower die are driven by the press to separate, and then the TV shell can be taken out.

[0003] However, when the upper die and the lower die of the existing stamping die are separated, the TV shell may get stuck on the surface of the upper die, so that the TV shell will rise with the upper die until it is separated from the lower die, and then it is necessary for workers to use tools to pry the side of the TV shell to separate the TV shell from the upper die. Such an operation is rather troublesome, with low work efficiency, and when workers use tools to pry the side of the TV shell, it is easy to damage the TV shell. Summary of the Utility Model

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1

[0022] A stamping die for producing a TV shell, as Figure 1 shown, includes a base 1, a lower die 2, an upper die 3, an electric push rod 4, a guide rod 7, a top plate 8 and a spring 9. The lower die 2 is fixedly connected to the top of the base 1. The upper die 3 is located directly above the lower die 2. Electric push rods 4 are symmetrically connected to the front and rear sides of the left and right sides of the upper die 3. The telescopic rods of the four electric push rods 4 are fixedly connected to the lower die 2. By controlling the telescopic rods of the four electric push rods 4 to shorten, the upper die 3 can move downward to complete the die closing operation with the lower die 2, so that the raw material is stamped and formed between the upper die 3 and the lower die 2 to make a TV shell of the required shape. First card slots 5 are symmetrically opened on the front and rear sides of the bottom of the upper die 3 in the left and right directions. Second card slots 6 are symmetrically opened on the front and rear sides of the top of the lower die 2 in the left and right directions. Guide rods 7 are symmetrically arranged on the front and rear sides of the top of the lower die 2 in the left and right directions. The tops of the four guide rods 7 slidably penetrate through the upper die 3. Top plates 8 are slidably arranged on the four guide rods 7. The top plates 8 are located between the first card slots 5 and the second card slots 6. When the upper die 3 and the lower die 2 are closed, the bottom surface of the top plate 8 is flush with the bottom surface of the upper die 3, and the top surface of the top plate 8 is flush with the top surface of the lower die 2. A spring 9 is connected between the bottom of each top plate 8 and the top of the lower die 2. The spring 9 is wound around the outside of the guide rod 7.

[0023] When stamping and forming the TV set shell, place the raw material to be processed in the lower die 2, and then control the telescopic rods of the four electric push rods 4 to shorten synchronously, so that the upper die 3 moves downward. When the first card slot 5 moves downward to contact the top plate 8, the end of the top plate 8 will be completely embedded in the first card slot 5. Subsequently, the upper die 3 can push the top plate 8 to slide downward along the guide rod 7. The downward movement of the top plate 8 compresses the spring 9. When the top plate 8 contacts the second card slot 6, the top plate 8 can be completely embedded in the second card slot 6. At this time, the upper die 3 and the lower die 2 complete the mold closing operation. Then, control the telescopic rods of the four electric push rods 4 to stop shortening, and apply pressure to the raw material in the lower die 2 through the upper die 3, so that it undergoes plastic deformation along the predetermined trajectory, and the raw material can be stamped and formed between the upper die 3 and the lower die 2 into a TV set shell of the required shape. Then, control the telescopic rods of the four electric push rods 4 to extend synchronously, so that the upper die 3 moves upward. The spring 9 will directly gradually return to its original state, driving the top plate 8 to rise synchronously with the upper die 3. The top plate 8 separates from the second card slot 6. When the spring 9 completely returns to its original state, under the action of the spring 9, the top plate 8 stops rising, while the upper die 3 will continue to rise, causing the top plate 8 to separate from the first card slot 5. At this time, if the TV set shell is stuck on the surface of the upper die 3, the top plate 8 will push the TV set shell stuck on the surface of the upper die 3 downward, so that the TV set shell automatically separates from the upper die 3 without manual operation, which is simple and convenient to operate, time-saving and labor-saving, and improves work efficiency.

[0024] As Figures 1 - 3 shown, it also includes a water tank 10, a water inlet pipe 11, a first water pump 12, a cooling pipe 13 and a circulating cooling component. The left part of the base 1 is fixedly connected with a water tank 10. The upper part of the front side of the water tank 10 is fixedly connected with a water inlet pipe 11. The right side of the top of the water tank 10 is bolted with a first water pump 12. The water inlet of the first water pump 12 is communicated with the water tank 10. The lower part of the lower die 2 is embedded with a cooling pipe 13. One end of the cooling pipe 13 is communicated with the water outlet of the first water pump 12. Through the first water pump 12, the water in the water tank 10 can be conveyed into the cooling pipe 13, so that the water in the cooling pipe 13 can absorb heat and cool the TV set shell formed in the lower die 2. A circulating cooling component is arranged on the base 1.

[0025] As Figure 3 shown, the circulating cooling component includes a collection tank 14, a second water pump 15 and a return pipe 16. The right part of the base 1 is fixedly connected with a collection tank 14. The other end of the cooling pipe 13 is communicated with the collection tank 14. The second water pump 15 is bolted to the rear part of the left side of the collection tank 14. A return pipe 16 is connected between the water outlet of the second water pump 15 and the rear part of the right side of the water tank 10. Through the action of the second water pump 15, the cooled water in the collection tank 14 can be conveyed back into the water tank 10 for recycling.

[0026] When the device needs to be used, an appropriate amount of water can be injected into the water tank 10 through the water inlet pipe 11; when the raw material is cooled between the upper die 3 and the lower die 2, the water in the water tank 10 can be passed into the cooling pipe 13 through the first water pump 12. The water in the cooling pipe 13 can absorb the heat on the surface of the raw material, accelerating the cooling speed of the stamped TV shell. Subsequently, the water in the cooling pipe 13 will flow into the collection tank 14 for natural cooling; when the water in the collection tank 14 is naturally cooled, the water in the collection tank 14 can be transported to the water tank 10 through the second water pump 15 and the return pipe 16 for replenishment, making rational use of water resources and improving the resource utilization rate.

[0027] As Figure 1 and Figure 3 shown, it further includes a cooling device 17, and the cooling device 17 is installed on the collection tank 14; through the cooling device 17, the water in the collection tank 14 can be quickly cooled, accelerating the cooling speed of the water in the collection tank 14 and improving the working efficiency.

[0028] As Figure 1 shown, it further includes a push-button switch 18. The push-button switch 18 is bolted to the right side of the upper die 3, and a groove for accommodating the push-button switch 18 is opened on the right side of the top of the lower die 2. The groove is located directly below the push-button switch 18; when the upper die 3 moves downward to close the mold with the lower die 2, the upper die 3 can drive the push-button switch 18 to move downward. When the push-button switch 18 contacts the lower die 2, it means that the upper die 3 and the lower die 2 have completed the mold closing work. At this time, the push-button switch 18 can accurately control the telescopic rods of the four electric push rods 4 to stop shortening, preventing the upper die 3 and the lower die 2 from being damaged due to excessive extrusion, and thus ensuring the stamping effect of the TV shell.

[0029] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
