Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, and in particular relates to a stamping die for a new energy battery cover. Background Technology

[0002] Stamping dies are special tools used for stamping and forming metal sheets. Through the mechanical force applied by the press, the metal sheet undergoes plastic deformation or separation between the punch and die of the die, thereby obtaining parts or semi-finished products with specific shapes, sizes and properties. Among them, the corresponding stamping dies are used in the preparation of new energy battery cover plates.

[0003] According to utility model application number CN202120858360.0, an integrated stamping die for a cover plate of a new energy power battery structural component is disclosed. The die body includes an upper die base and a lower die base. Guide sleeves are provided on the lower surface of the upper die base near the four corners. Guide posts that cooperate with the guide sleeves are fixedly provided on the upper surface of the lower die base. The upper die base is provided with a clearance hole that cooperates with the guide sleeve. A movable plate is provided on the inner side of the clearance hole near the lower end. A spring is provided on the upper side of the movable plate, and a pressure plate is provided on the upper side of the spring to press and limit it.

[0004] The above technical solution uses the cooperation of guide pillars and guide sleeves to achieve guidance. When the guide pillar enters the inner side of the clearance hole and abuts against the movable plate, the movable plate is elastically pressed by the spring to achieve shock absorption and buffering. This reduces the impact force of the upper and lower molds colliding at the moment of mold closing, effectively reducing mold cracking and extending the service life of the mold. However, in the above technical solution, the mold core still needs to be installed inside the mold during use. However, the installation and disassembly of the mold core is relatively cumbersome and requires the use of tools such as wrenches, so it is inconvenient to replace the mold core.

[0005] Therefore, we propose a stamping die for new energy battery covers to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to solve the problem of inconvenience in replacing the mold core in the existing technology, and to propose a new energy battery cover stamping mold.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A stamping die for a new energy battery cover includes a first die frame and a second die frame located below the first die frame. The bottom surface of the first die frame is in contact with the upper surface of the second die frame. The inner walls of the second die frame and the inner walls of the first die frame are rotatably connected to a first rotating shaft and a second rotating shaft. Two first gears are slidably connected to the outer surface of each first rotating shaft, and two second gears are slidably connected to the outer surface of each second rotating shaft. A toothed plate meshes with the outer surface of each first gear. A movable plate is fixedly connected to the side of each pair of toothed plates that are close to each other. The outer surfaces of the two movable plates are slidably connected to the interiors of the first die frame and the second die frame, respectively. A transmission gear is fixedly connected to the right end of each first rotating shaft and the right end of the second rotating shaft. A transmission belt meshes with the outer surface of each set of transmission gears.

[0009] Preferably, the upper surface of the second mold frame is fixedly connected with two sets of positioning shafts, each set of positioning shafts has two shafts, the outer surface of each positioning shaft is slidably connected to the inside of the first mold frame, and the outer surface of the first mold frame has two sets of connecting ports, each set of connecting ports has two ports.

[0010] Preferably, rectangular openings are provided on both sides of the first mold frame and both sides of the second mold frame, and a baffle is snapped into the interior of each rectangular opening.

[0011] Preferably, each set of baffles has a locking shaft fixedly connected to one side of each other, and the two sides of the first mold frame and the two sides of the second mold frame are provided with locking grooves, and the outer surface of each locking shaft is engaged with the inside of the locking groove.

[0012] Preferably, a rectangular block is fixedly connected to one of the opposite sides of each group of toothed plates, a roller is rotatably connected to the inner wall of each rectangular block, and a wheel is fixedly connected to the outer surface of each roller.

[0013] Preferably, the inner walls of both the first mold frame and the second mold frame are provided with rectangular grooves, and the outer surface of each roller is slidably connected to the interior of the rectangular groove.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] By incorporating a first rotating shaft, the mold core is in close contact with it during installation. A rubber pad covering the surface of the first rotating shaft converts the power generated during installation into rotational power, which is then transmitted to the first gear. The meshing relationship between the first gear and the gear plate drives the gear plate to move towards the mold core, ensuring close contact between the moving plate and the other side of the mold core. Simultaneously, while the rotation of the first rotating shaft transmits power to the second rotating shaft via transmission gears and belts, the second gear, which is slidably connected to the surface of the second rotating shaft, does not mesh with the gear plate. Therefore, the second gear does not affect the movement of the gear plate. Subsequently, the two first gears are moved to the sides, causing the first gear... The wheel no longer meshes with the toothed plate. Instead, it moves the two second gears closer together, causing them to mesh with the toothed plate. Then, when the mold core receives upward force, it will transmit the force to the first gear again. However, the first gear is not meshing with the toothed plate at this time, so the toothed plate cannot move to the right. Consequently, it cannot move the moving plate forward, and thus cannot disengage the contact between the moving plate and the mold core. When the first shaft rotates, it transmits the force to the second shaft through the transmission gear and transmission belt. However, the second shaft is located below the toothed plate, so the second shaft and the second gear will instead push the toothed plate to continue moving backward, thus allowing the mold core to make closer contact with the moving plate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 A stamping die for a new energy battery cover includes a first die frame 1 and a second die frame 5 below the first die frame 1. The bottom surface of the first die frame 1 is in contact with the upper surface of the second die frame 5. Two sets of positioning shafts 10 are fixedly connected to the upper surface of the second die frame 5. Each set of positioning shafts 10 has two shafts. The outer surface of each positioning shaft 10 is slidably connected to the inside of the first die frame 1. The outer surface of the first die frame 1 has two sets of connecting ports 2. Each set of connecting ports 2 has two ports. By setting the positioning shafts 10, the positioning shafts 10 can be used to prevent misalignment when the first die frame 1 and the second die frame 5 are docked. The connecting ports 2 can discharge the compressed air when the positioning shafts 10 enter the inside of the first die frame 1.

[0024] The inner wall of the second mold frame 5 and the inner wall of the first mold frame 1 are rotatably connected to a first rotating shaft 4 and a second rotating shaft 3. Two first gears 17 are slidably connected to the outer surface of each first rotating shaft 4, and two second gears 18 are slidably connected to the outer surface of each second rotating shaft 3. Rectangular openings 7 are provided on both sides of the first mold frame 1 and both sides of the second mold frame 5. A baffle 6 is engaged inside each rectangular opening 7. By providing rectangular openings 7, the positions of the first gears 17 and the second gears 18 can be adjusted.

[0025] Each first gear 17 has a toothed plate 16 meshing on its outer surface. A movable plate 14 is fixedly connected to the side of each pair of toothed plates 16 that are close to each other. The outer surfaces of the two movable plates 14 are slidably connected to the interior of the first mold frame 1 and the second mold frame 5, respectively. A retaining shaft 8 is fixedly connected to the side of each set of baffles 6 that are close to each other. The two sides of the first mold frame 1 and the two sides of the second mold frame 5 are provided with retaining grooves 9. The outer surface of each retaining shaft 8 is engaged with the interior of the retaining groove 9. By setting the retaining grooves 9 and retaining shafts 8, and by utilizing the engaging relationship of the retaining shaft 8 engaged with the interior of the retaining groove 9, the baffles 6 can be connected to the two sides of the first mold frame 1 and the second mold frame 5.

[0026] A transmission gear 20 is fixedly connected to the right end of each first rotating shaft 4 and the right end of each second rotating shaft 3. A rectangular block 13 is fixedly connected to the side of each set of toothed plates 16 that is far apart from each other. A roller 11 is rotatably connected to the inner wall of each rectangular block 13. A roller 12 is fixedly connected to the outer surface of each roller 11. By setting the roller 12, the roller 12 can provide support for the toothed plate 16, making the movement of the toothed plate 16 more stable.

[0027] Each set of transmission gears 20 has a transmission belt 19 meshing on its outer surface. The inner walls of the first mold frame 1 and the second mold frame 5 are provided with rectangular grooves 15. The outer surface of each roller 12 is slidably connected to the inside of the rectangular groove 15. By providing the rectangular groove 15, the roller 12 can be guided to move by utilizing the sliding relationship between the rectangular groove 15 and the roller 12.

[0028] The working principle of this utility model is as follows: When the mold core is installed, it needs to be in close contact with the first rotating shaft 4. The rubber pad covering the surface of the first rotating shaft 4 can stably convert the power generated during the installation of the mold core into rotational power and transmit it to the first gear 17. Thus, the meshing relationship between the first gear 17 and the toothed plate 16 can drive the toothed plate 16 to move towards the position of the mold core, so that the moving plate 14 can be in close contact with the front of the mold core. At the same time, when the first rotating shaft 4 rotates, it transmits power to the second rotating shaft 4 through the transmission gear 20 and the transmission belt 19. On shaft 3, however, the second gear 18, which is slidably connected to the surface of the second rotating shaft 3, does not mesh with the toothed plate 16. Therefore, the second gear 18 will not affect the movement of the toothed plate 16. After the mold core is installed, the bottom surface of the mold core will be at the bottom of the inner cavity of the second mold frame 5, and the moving plate 14 will be in close contact with the mold core. In addition, the contact surface between the moving plate 14 and the mold core is covered with a layer of rubber, which can greatly increase the friction between the moving plate 14 and the mold core. Then, the two first gears 17 are moved to the sides, so that the first gears 17 no longer mesh with the toothed plate 16. The two second gears 18 are moved closer together to engage with the toothed plate 16. When the mold core receives an upward force, the force is transmitted to the first gear 17 again. However, the first gear 17 is not engaged with the toothed plate 16 at this time, so the toothed plate 16 cannot move to the right. Consequently, it cannot move the moving plate 14 forward, and thus cannot disengage the contact between the moving plate 14 and the mold core. When the first rotating shaft 4 rotates, it transmits the force to the second rotating shaft 3 through the transmission gear 20 and the transmission belt 19. However, the second rotating shaft 3 is located below the toothed plate 16, so the second rotating shaft 3 and the second gear 18 will push the toothed plate 16 to continue moving backward, so that the mold core can be in closer contact with the moving plate 14, thereby increasing the stability of the mold core. This continues until the first mold frame 1 and the second mold frame 5 are installed. When the mold core needs to be disassembled, the first gear 17 is engaged with the toothed plate 16, and the second gear 18 is not engaged with the toothed plate 16, thus effectively avoiding the problem of inconvenience in replacing and installing the mold core during the use of the equipment.
