There are four of each of the first movable seat 803, the second movable seat 810, the damper 804, the swing rod 805, the slider 806, and the second slide rod group 808. There are multiple springs 809 and the same number of stop rings 802.

[0023] Specifically, the bottom center of the ejector plate 801, near the periphery, is fixedly connected to the top of four second movable seats 810. The swing ends of the four second movable seats 810 are movably connected to one end of four swing rods 805. The ends of the four swing rods 805, away from the adjacent second movable seats 810, are movably connected to the swing ends of four first movable seats 803. The bottoms of the four first movable seats 803 are fixedly connected to the top of four sliders 806.

[0024] Specifically, each of the four second slide bar groups 808 consists of two slide bars. The four sides of the connecting block 807 near the corners are fixedly connected to one end of the slide bar in each of the four second slide bar groups 808. The end of the slide bar in the second slide bar group 808 away from the connecting block 807 is fixedly connected to the inner four sides of the forming mold 9.

[0025] Specifically, the mounting ends of the four dampers 804 are fixedly connected to the inner four sides of the forming mold 9, the four dampers 804 are located in the middle of the second slide bar group 808, the output ends of the four dampers 804 are fixedly connected to the opposite ends of the four sliders 806, and the inside of the slider 806 is movably sleeved with the outer surface of the slide bar in the second slide bar group 808.

[0026] Specifically, the outer surfaces of the slide rods in the four second slide rod groups 808 are respectively movably connected to the interior of multiple springs 809, one end of each spring 809 is fixedly connected to the opposite end of each of the four sliders 806, the outer surfaces of the slide rods in the four second slide rod groups 808 are respectively snapped into the interior of multiple stop rings 802, and the ends of each spring 809 away from the sliders 806 are respectively fixedly connected to the adjacent ends of multiple moving rings.

[0027] Specifically, the four first movable seats 803 and the second movable seats 810 are connected to the four swing rods 805 by pins.

[0028] Specifically, limiting grooves are provided on all four sides of the through groove 7. The top of the ejector plate 801 passes through the through groove 7 and extends out of the top of the forming mold 9. Limiting blocks are provided on all four walls of the ejector plate 801. The outer surface of the limiting block on the ejector plate 801 is movably connected to the inside of the limiting groove on the through groove 7.

[0029] Specifically, the output end of the hydraulic telescopic rod 5 passes through the top of the fixed plate 4 and extends out of the bottom of the fixed plate 4, and is fixedly connected to the middle of the connecting plate 3. The tops of the two first sliding rods 6 pass through the bottom of the fixed plate 4 near the left and right sides and extend out of the top of the fixed plate 4. The connection points of the two first sliding rods 6 and the fixed plate 4 are movably sleeved. Sliding grooves are provided at the four corners of the top of the connecting plate 3. The outer surfaces of the multiple support columns 2 are movably sleeved with the inside of the sliding grooves on the connecting plate 3. A controller is fixedly installed on the top of the fixed plate 4. The stamping die 10 and the forming die 9 are symmetrically arranged.

[0030] In use, the output end of the hydraulic telescopic rod 5 of the battery plate to be stamped drives the connecting plate 3 to move along the support column 2, so that the bottom of the stamping die 10 is pressed against the top of the forming die 9, thereby stamping the battery plate to be stamped by the stamping die 10. When the bottom of the stamping die 10 is pressed against the forming die 9, the ejector plate 801 in the ejector device 8 is also under pressure. The ejector plate 801 retracts into the through groove 7. After the ejector plate 801 is pressed, it triggers a series of chain reactions in the ejector device 8. Specifically, the downward pressure of the ejector plate 801 pushes the swing frame. The end of the swing frame away from the second movable seat 810 acts on the indirectly connected slider 806. Since the slider 806 and the second slide rod group 808 are in a movable sleeve relationship, under the push of the swing frame, the two sliders 806 are pushed and move along the second slide rod group 808 towards The slider 806 moves smoothly and stably in the opposite direction. As the slider 806 moves, the spring 809 gradually compresses, and the output end of the damper 804 also contracts, storing the necessary energy for the subsequent reset action. This continues until the bottom of the stamping die 10 is pressed against the top of the forming die 9. At this point, the stamping die 10 and the forming die 9 stamp the material. After the battery plate to be stamped is formed, the output end of the hydraulic telescopic rod 5 retracts, thereby driving the connecting plate 3 to move upward along the support column 2, along with the stamping die 10 and the first slide rod 6. At the same time, the spring 809 in the ejector device 8 begins to extend due to its own elasticity, pushing the slider 806 to move in the opposite direction. The output end of the damper 804 also gradually extends, driving the swing frame to reset, and then the stamped battery plate is ejected by the ejector plate 801 for easy removal.

[0031] In summary, this new energy battery plate stamping fixture, by setting an ejector device 8, automatically ejects the formed battery plate from the forming mold 9 after stamping through spring 809 reset and damper 804 buffering, without the need for manual or additional robotic intervention, thus shortening the demolding time for a single workpiece. The damper 804, in combination with spring 809, can greatly increase the service life of spring 809 and simultaneously control the ejection speed, preventing the workpiece from popping out due to inertia.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
