[0025] Specifically, the base 1 is used to support various parts. The threaded rod 2 rotates inside the base 1 and is used to drive the moving frame 3 to move up and down when the threaded rod 2 rotates. Connecting rods 4 are arranged on both the left and right sides of the moving frame 3 and are used to connect the moving frame 3 to the sliding frame 5. When the moving frame 3 moves, the sliding frame 5 will move. The sliding frame 5 is used to drive the clamping hand 6 at the top to move. The clamping hand 6 is used to fix the lower die 7. The lower die 7 is used to determine the outer diameter size of the output shaft. Two slide rails 8 are arranged on the top of the base 1 and are used to support the movement of the sliding frame 5. A motor 9 is arranged at the bottom of the base 1 and is used to drive the threaded rod 2 to rotate. Support rods 10 are arranged on the top of the base 1. The support rods 10 are used to fix the support plate 11. The support plate 11 is used to support the extrusion device 12. The extrusion device 12 is a prior art and is used to extrude the inner hole die 15 into the lower die 7 for cold extruding the output shaft. A mounting plate 13 is arranged at the bottom of the extrusion device 12 and is used to mount the fixing plate 14. The fixing plate 14 is used to support the inner hole die 15.

[0026] Refer to Figure 3 - Figure 4, the quick-release component includes a sliding plate 17 and a support frame 18. The sliding plate 17 is slidably connected inside the mounting plate 13. The support frame 18 is fixedly connected to the bottom of the mounting plate 13. At the top of the support frame 18, a plurality of springs 19 are fixedly connected. The tops of the plurality of springs 19 are all fixedly connected to the bottom of the sliding plate 17. Two chutes 20 are formed inside the sliding plate 17. Inside each of the two chutes 20, a baffle 21 is fixedly connected. At the top of the fixing plate 14, two insertion rods 16 are fixedly connected. The two insertion rods 16 are respectively slidably connected inside the two chutes 20. On the outer periphery of the mounting plate 13, two slots 23 are formed. On the outer periphery of the sliding plate 17, two lever rods 22 are fixedly connected. The two lever rods 22 are respectively slidably connected inside the two slots 23.

[0027] Specifically, the sliding plate 17 slides inside the mounting plate 13. The support frame 18 is arranged at the bottom of the mounting plate 13. The support frame 18 is used to support the spring 19. The spring 19 is used to always apply an upward force to the sliding plate 17. Inside the sliding plate 17, a chute 20 is formed. At both ends of the chute 20, there are round grooves with the same size as the insertion rods 16 at the top of the inner hole mold 15, for the insertion rods 16 to enter the top of the sliding plate 17. At one end of the chute 20, a baffle 21 is fixed, for preventing the insertion rods 16 moving to this position from falling, so that the fixing plate 14 is fixed under the mounting plate 13.

The mounting plate 13 is provided with slots 23, for providing movement for the lever rods 22.

[0028] Working principle: When it is necessary to remove the lower mold 7 and replace it with a lower mold 7 of a different size, start the motor 9 to drive the threaded rod 2 to rotate, so that the moving frame 3 moves upward. When the moving frame 3 moves, it will drive the sliding frame 5 to move on the slide rail 8 through the connecting rod 4, so that the clamping hand 6 no longer fixes the lower mold 7, and the lower mold 7 can be removed. When installing a lower mold 7 of other sizes, first place the lower mold 7 on the base 1, drive the motor 9 to reverse, so that the moving frame 3 moves downward, so that the clamping hand 6 fixes the lower mold 7 again, and the installation can be successful. Different-sized output shaft molds can be quickly replaced.

[0029] When it is necessary to replace the inner hole mold 15, first dial the lever rod 22 downward, so that the sliding plate 17 moves downward, enabling the fixing plate 14 to rotate. Rotate the fixing plate 14 so that the insertion rods 16 move from one end of the chute 20 to the other end, and then the fixing plate 14 can be removed, so that the inner hole mold 15 is removed. When installing the inner hole mold 15, first install the insertion rods 16 towards the end of the chute 20 without the baffle 21. After installing to the top, dial the lever rod 22 downward, then rotate the fixing plate 14 so that the insertion rods 16 move to the end of the chute 20 with the baffle 21. Release the force on the lever rod 22, and the spring 19 releases the tension to move the sliding plate 17 upward, so that the insertion rods 16 are fixed by the baffle 21, and the installation can be completed. Different-sized output shaft inner hole molds 15 can be quickly replaced.
