[0022] Please see Figures 1 to 4 This utility model provides a multi-nail making machine with quick mold replacement, including a nail making machine body 1 and a mold 3. The nail making machine body 1 is fixedly installed with a mounting base 2 located below the stamping column. The top of the mounting base 2 is provided with a fixing slot 11. The middle of the mold 3 is rotatably connected to a transmission rod 4. The bottom of the mold 3 is provided with a moving slot 9 corresponding to the fixing slot 11. The mold 3 is rotatably connected with threaded rods 7 located on both sides of the transmission rod 4. A driving bevel gear 6 is fixedly installed in the middle of the transmission rod 4. A crank handle slot 5 is fixedly installed at one end of the transmission rod 4. A follower bevel gear 8 is fixedly installed at one end of the threaded rod 7. The follower bevel gear 8 and the driving bevel gear 6 are connected. A locking block 10 is slidably connected inside the moving slot 9. The threaded rod 7 and the locking block 10 are connected. The middle part of the 0 is threaded through, and the bottom of the snap-fit ​​block 10 is snapped into the inside of the fixed slot 11. By setting the fixed slot 11 and the snap-fit ​​block 10, when changing the mold 3, the crank handle and crank handle slot 5 drive the transmission rod 4 to rotate, and then drive the threaded rod 7 to rotate through the active bevel gear 6 and follower bevel gear 8, so that the snap-fit ​​block 10 moves along the fixed slot 11 and the moving slot 9, so that the snap-fit ​​block 10 is released from the fixed slot 11, and the mold 3 can be easily removed. After replacing the new mold 3, the crank handle slot 5 is turned in the opposite direction, so that the snap-fit ​​block 10 moves into the fixed slot 11 and fixes the new mold 3 on the mounting base 2. The mold 3 can be quickly and easily removed or installed from the mounting base 2, which greatly shortens the time for adjusting or replacing the mold 3.

[0023] The front of the crank slot 5 is flush with the front of the mold 3, and a hexagonal groove is provided on the front of the crank slot 5.

[0024] The mold 3 has a sliding connection to a connecting rod 13 located above the crank slot 5. One end of the connecting rod 13 is fixedly installed with a button 14 that is slidably connected to the inside of the mold 3, and the other end of the connecting rod 13 is fixedly installed with a pawl 15 located inside the mold 3.

[0025] The transmission rod 4 is fixedly equipped with a ratchet 12 located behind the crank slot 5. The ratchet 12 and the pawl 15 are tightly abutted together. A clamping spring 16 is provided on the rear side of the pawl 15. By setting the ratchet 12 and the pawl 15, when changing the mold 3, pressing the button 14 causes the connecting rod 13 to push the pawl 15 to move to the rear, so that the pawl 15 and the ratchet 12 are disengaged, and the transmission rod 4 can rotate. When fixing the new mold 3, the ratchet 12 rotates normally. When the locking block 10 is locked inside the fixing slot 11, the clamping spring 16 pushes the pawl 15 and the ratchet 12 to lock together, preventing the locking block 10 from loosening.

[0026] Two follower bevel gears 8 mesh with the two sides of the driving bevel gear 6, and the two follower bevel gears 8 are symmetrically arranged on both sides of the driving bevel gear 6.

[0027] The threaded rods 7 located on both sides of the transmission rod 4 rotate in opposite directions, and the ends of the threaded rods 7 are flush with the two ends of the mold 3.

[0028] A limiting piece 17 is fixedly installed at the end of the threaded rod 7, and a limiting groove 18 is opened at the end of the snap block 10 away from the transmission rod 4. The diameter of the limiting groove 18 is the same as the diameter of the limiting piece 17.

[0029] Working principle:

[0030] When changing mold 3, press button 14 to push the connecting rod 13 to move the pawl 15 to the rear, causing the pawl 15 to disengage from the ratchet 12. The transmission rod 4 can then rotate, driving the transmission rod 4 through the crank handle and crank handle slot 5. This, in turn, drives the threaded rod 7 to rotate through the active bevel gear 6 and follower bevel gear 8, causing the locking block 10 to move along the fixed slot 11 and the moving slot 9. This disengages the locking block 10 from the fixed slot 11, making it easy to remove mold 3. After replacing with a new mold 3, reverse the crank handle slot 5 to move the locking block 10 into the fixed slot 11. The ratchet 12 rotates normally. Once the locking block 10 is locked inside the fixed slot 11, the locking spring 16 pushes the pawl 15 to lock with the ratchet 12, preventing the locking block 10 from disengaging. This fixes the new mold 3 on the mounting base 2. Mold 3 can be quickly and easily removed from or installed on the mounting base 2, greatly shortening the time for adjusting or replacing mold 3.
