The ejecting component 4 includes a sleeve 401, a ejector pin 402, a movable plate 403, a buffer spring 404, a chute 405, a slider 406 and a buffer pad 407. The sleeve 401 is arranged on the top side of the installation plate 3. The ejector pin 402 is arranged inside the sleeve 401. The bottom end of the ejector pin 402 is provided with a movable plate 403. A buffer spring 404 is arranged on the bottom surface of the ejector pin 402.

A buffer pad 407 is arranged at the inner bottom of the sleeve 401;

[0025] By providing the ejecting component 4, it can play a buffering effect when ejecting the workpiece, avoiding the workpiece being scratched by the ejector pin. When the ejector pin 402 ejects the workpiece, the top end of the ejector pin 402 is stressed, causing it to drive the movable plate 403 to move downward. During the movement, the buffer spring 404 deforms to play a buffering role, and it cooperates with the buffer pad 407 to play a double buffering effect.

[0026] Please refer to Figures 1 to 3 , The sleeve 401 is fixedly connected to the top side of the installation plate 3. The ejector pin 402 is slidably connected to the inside of the sleeve 401. The movable plate 403 is fixedly connected to the bottom end of the ejector pin 402. The buffer spring 404 is sleeved on the surface of the ejector pin 402. The sliders 406 are fixedly connected to both sides of the movable plate 403. The buffer pad 407 is placed at the inner bottom of the sleeve 401, and the top is in contact with the movable plate 403;

[0027] By the driving component 5 pushing the adjusting plate 502 and the installation plate 3 to move upward, the ejecting component 4 is driven to move upward at the same time, so that the top end of the ejector pin 402 gradually applies a supporting force to the workpiece to eject the workpiece.

[0028] Please refer to Figures 1 to 4 , A driving component 5 is arranged on one side of the installation plate 3. The driving component 5 includes a stud 501, an adjusting plate 502, a nut 503, an L-shaped plate 504, a driving motor 505, and a cam 506. A stud 501 is fixedly connected to one side surface of the installation plate 3. The adjusting plate 502 is sleeved on the surface of the stud 501. One end of the stud 501 is threadedly connected to a nut 503. An L-shaped plate 504 is fixedly connected to one side surface of the base 1. A driving motor 505 is fixedly installed on the outside of the L-shaped plate 504. The output shaft of the driving motor 505 is fixedly connected to a cam 506;

[0029] [[ID=Nineteen]]By providing the driving component 5, the ejecting height of the ejecting component 4 can be adjusted. By moving the vertical position of the adjusting plate 502 and adjusting the vertical height of the adjusting plate 502, the maximum rising height of the installation plate 3 and the ejecting component 4 can be adjusted.

[0030] Please refer to Figures 1 to 2 Figures 1 to 2 , a guiding column 2 is fixedly connected to the upper surface of the base 1, the mounting plate 3 is sleeved on the surface of the guiding column 2, the top end of the guiding column 2 is fixedly connected to a workbench 6, a lower mold 7 is fixedly connected to the upper surface of the workbench 6, limiting rods 8 are fixedly connected to the four corners of the upper surface of the workbench 6, the top ends of the limiting rods 8 are fixedly connected to a top plate 9, a hydraulic cylinder 10 is fixedly installed on the top of the top plate 9, the output end of the hydraulic cylinder 10 is fixedly connected to a sliding plate 11, a pressing mold 12 is fixedly installed at the bottom of the sliding plate 11, and a reset disc spring is installed between the mounting plate 3 and the workbench 6;

[0031] After the ejecting assembly 4 ejects the workpiece, its cam 506 turns to one side, and then through the reset disc spring between the mounting plate 3 and the workbench 6, the mounting plate 3 and the ejecting assembly 4 can be reset.

[0032] In the present utility model, the working principle of the device is as follows:

[0033] During use, the aluminum alloy forging to be stamped is placed in the lower mold 7, and then the hydraulic cylinder 10 drives the sliding plate 11 and the pressing mold 12 to descend horizontally, so that the pressing mold 12 stamps the workpiece. After stamping is completed, the pressing mold 12 is driven by the hydraulic cylinder 10 to reset. Then, the driving motor 505 is started to drive the cam 506 to rotate, so that one side of the cam 506 pushes the adjusting plate 502. Under the limiting action of the guiding column 2, the adjusting plate 502 and the mounting plate 3 can be pushed to move upward, and at the same time, the ejecting assembly 4 is driven to move upward, so that the top end of the ejector pin 402 gradually applies a supporting force to the workpiece to eject the workpiece. When the ejector pin 402 ejects the workpiece, the top end of the ejector pin 402 is stressed, which drives the movable plate 403 to move downward. During the movement, the buffer spring 404 is deformed, and together with the buffer pad 407, it plays a double buffering effect, absorbing the acting force brought by the ejection and avoiding scratching the workpiece. And when the movable plate 403 moves, it can drive the slider 406 to slide in the chute 405, making the movement of the ejector pin 402 more stable;

[0034] When it is necessary to adjust the ejection height of the ejecting assembly 4, the nut 503 can be loosened to increase the distance between one side of it and the adjusting plate 502. Then, the vertical position of the adjusting plate 502 can be moved. By adjusting the vertical height of the adjusting plate 502, the maximum rising height of the mounting plate 3 and the ejecting assembly 4 can be adjusted, so as to adjust the ejection height of the ejecting assembly 4. After adjustment, the position is fixed by tightening the nut 503.
