[0002] Batteries are the product of the development of modern society. They are particularly important in some places where there is no timely fixed power supply. The production technology of batteries has also become more and more perfect. From the previous aluminum battery shell to the current steel shell, its physical properties are more stable and its pressure resistance is stronger. The battery steel shell needs to be stamped through a mold during the production process. It still has the following disadvantages in actual use.

[0003] For example: Publication No.: CN218591613U discloses a battery steel shell continuous stamping die, wherein the back sides of the base and the top plate are provided with a back side plate, and a limiting groove is provided at the middle position of the upper surface of the base, and push plates are slidably installed inside the two concave molds, and a storage groove adapted to the push plate is provided at one end of the two concave molds, and a transmission cavity is provided inside the storage groove, and a threaded rod is symmetrically rotated and installed inside the transmission cavity, and a threaded sleeve rod that penetrates the transmission cavity and is fixedly connected to the push plate is connected to the threaded rod. The utility model drives the two threaded rods to rotate synchronously through a transmission assembly, and the threaded sleeve rod is pushed to slide under the threaded connection between the threaded rod and the threaded sleeve rod, and further enables the threaded sleeve rod to push the push plate to slide, which is beneficial to the ejection of the blank formed inside the concave mold, avoiding manual operation, and improving the safety and work efficiency of the equipment, but it still has the following disadvantages in actual use:

[0004] During the use of the mold in the above-mentioned comparative document, the upper mold and the lower mold are combined to complete the stamping of the steel plate. The steel plate will deform during the stamping process. The deformation of the metal will generate a large amount of heat. As the stamping continues uninterruptedly, the heat will become higher and higher. After being heated for a long time, the upper mold and the lower mold will undergo a certain amount of expansion deformation. This deformation will greatly affect the production accuracy of the battery steel shell and greatly reduce the stability and quality of the product. Utility Model Content

A limiting mechanism 7 is fixedly connected to one side of the mounting frame 5;

[0026] When in use, the mounting frame 5 cooperates with the circulation pipe 6 to extend into the upper mold 3 and the lower mold 2, and the circulation pipe 6 is close to the mold core of the upper mold 3 and the lower mold 2. When continuous and uninterrupted stamping is performed, the water pump 402 is started, and the water pump 402 can draw out the cooling water in the water tank 4 and pump it into the circulation pipe 6 through the three-way joint 403 and the hose 405. Then the cooling water in the circulation pipe 6 will flow into the water tank 4 again through the hose 405 and the three-way joint 404, and the cycle is repeated, so as to continuously take away the heat from the upper mold 3 and the lower mold 2, and cool down the upper mold 3 and the lower mold 2, thereby improving the stability and quality of the product. As the working time continues to increase, when the water in the water tank 4 cannot dissipate heat efficiently, the semiconductor refrigeration plate 401 can be started to quickly cool the water in the water tank 4, thereby further improving the cooling effect on the upper mold 3 and the lower mold 2.

One end of the winding shaft 702 is fixedly connected to a force block 7021. The outer circumferential surface of the winding shaft 702 is fixedly connected to a pair of metal fiber ropes 703.

[0028] During use, when the installation frame 5 needs to be disassembled, the thumb and index finger pinch and rotate the force block 7021, and the force block 7021 will drive the winding shaft 702 to rotate during the rotation. The rotating winding shaft 702 will reel the metal fiber rope 703. During the reeling process of the metal fiber rope 703, the latch 705 will gradually fall off the limit piece 707. At this time, the thumb and index finger of the personnel are still pinching the force block 7021. When the latch 705 is separated from the limit piece 707, the personnel can pull out the installation frame 5, which is convenient for the personnel to disassemble the installation frame 5.

As the working time continues to extend, When the water in the water tank 4 cannot dissipate heat efficiently, the semiconductor refrigeration plate 401 can be started to quickly cool the water in the water tank 4. When the installation frame 5 needs to be disassembled, the thumb and index finger pinch and rotate the force block 7021. The force block 7021 will drive the winding shaft 702 to rotate during the rotation, and the rotating winding shaft 702 will reel the metal fiber rope 703. During the reeling process of the metal fiber rope 703, the pin 705 will gradually fall off the limit piece 707. At this time, the thumb and index finger of the personnel are still pinching the force block 7021. When the pin 705 is separated from the limit piece 707, the personnel can pull out the installation frame 5, which is convenient for the personnel to disassemble the installation frame 5, thereby completing the entire process.
