Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4. This utility model provides a technical solution:

[0025] Quick mold change and positioning structure for metal button stamping dies

[0026] It includes a positioning mechanism, which is located inside the stamping base 2 and is used to position the stamping die 3 for die changing.

[0027] The stamping base 2 is located inside the stamping machine body 1, and the stamping die 3 is positioned above the stamping base 2 via a positioning mechanism;

[0028] The stamping die 3 includes a fixed rod 5, a buffer assembly for buffering the fixed rod 5, a positioning assembly for positioning the fixed rod 5, and a drive assembly for positioning the fixed rod 5.

[0029] The fixing rod 5 is bolted to the bottom of the stamping die 3. The surface of the stamping base 2 is provided with a slot 8. The fixing rod 5 is inserted into the inside of the slot 8. The buffer assembly is set inside the slot 8. The positioning assembly is set on both sides of the slot 8.

[0030] By bolting the fixing rod 5 to the bottom of the stamping die 3, and opening a slot 8 on the surface of the stamping base 2, the fixing rod 5 is inserted into the inside of the slot 8. The positioning components are set on both sides of the slot 8. The fixing rod 5 inserted into the slot 8 is fixed and positioned by the positioning components, thereby realizing the need for positioning and changing the stamping die 3, which is more time-saving and labor-saving.

[0031] The positioning component includes a mounting slot 11, a clamping frame 16, and a locking block 18. A notch 6 is symmetrically provided on the outer arc surface below the fixing rod 5. Mounting slots 11 are provided on both sides of the slot 8 inside the stamping base 2. The drive component is located inside the mounting slot 11. A placement slot 19 is provided in the middle of the slot 8 below the two sets of mounting slots 11. Two sets of clamping frames 16 are provided. Locking blocks 18 are provided inside the opposite side walls of the two sets of clamping frames 16. The locking blocks 18 are inserted into the inside of the notch 6.

[0032] The stamping base 2 has mounting slots 11 on both sides of the slot 8. The middle of the slot 8 has a placement slot 19 below the two mounting slots 11. The placement slot 19 has symmetrical clamping frames 16 inside. The two clamping frames 16 have locking blocks 18 inside their opposite side walls. The locking blocks 18 are inserted into the recesses 6 on the outer arc surface of the fixing rod 5. The locking blocks 18 are inserted into the recesses 6 to fix and position the fixing rod 5, thereby positioning the stamping die 3 bolted to the top of the fixing rod 5.

[0033] The drive assembly includes a telescopic rod 12, a compression spring 13, an L-shaped frame 14, and a transmission module. The telescopic rod 12 is respectively disposed on the inner wall of the mounting groove 11 away from the slot 8. The working end of the telescopic rod 12 is fixedly installed on the inner side wall of the L-shaped frame 14. The outer side wall of the L-shaped frame 14 is fixedly installed on the compression spring 13. The end of the compression spring 13 is fixedly installed on the other inner wall of the mounting groove 11. The transmission module is disposed between the L-shaped frame 14 and the clamping frame 16.

[0034] The transmission module includes teeth 15 and rotating gears 17. Teeth 15 are respectively disposed on the side walls opposite to the L-shaped frame 14 and the clamping frame 16. Rotating gears 17 are rotatably disposed between the L-shaped frame 14 and the clamping frame 16. Rotating gears 17 are meshed with teeth 15 disposed on the side walls opposite to the L-shaped frame 14 and the clamping frame 16.

[0035] A telescopic rod 12 is provided on the inner wall of the mounting groove 11 away from the slot 8. The working end of the telescopic rod 12 is fixedly installed on the inner side wall of the L-shaped frame 14. A compression spring 13 is provided between the outer side wall of the L-shaped frame 14 and the inner wall of the mounting groove 11 on the other side. The side walls of the L-shaped frame 14 and the lower clamping frame 16 are provided with teeth 15. A rotating gear 17 is rotatably provided between the L-shaped frame 14 and the clamping frame 16. The rotating gear 17 meshes with the teeth 15 on the side walls of the L-shaped frame 14 and the clamping frame 16. The original position of the two sets of clamping frames 16 is set inside the slot 8, and the side walls of the two sets of clamping frames 16 are in contact with each other.

[0036] When the stamping die 3 needs to be installed, the worker first bolts the fixing rod 5 to the bottom of the stamping die 3. After installation, the telescopic rod 12 extends the inner rod, and the L-shaped frame 14 is driven to compress the compression spring 13. At this time, the teeth 15 on the bottom surface of the L-shaped frame 14 mesh with the rotating gear 17, thereby driving the two sets of clamping frames 16 to move towards the outside of the stamping base 2 at the same time. Then, the fixing rod 5 is placed above the movable seat 7 and pressed into the slot 8. After the bottom surface of the movable seat 7 and the surface of the support column 10 come into contact with each other, the inner rod of the telescopic rod 12 retracts, and the clamping frame 16 is driven to move towards the fixing rod 5, so that the locking block 18 is inserted into the inside of the recess 6, realizing the need to fix and position the fixing rod 5. This operation enables the stamping die 3 to be changed quickly.

[0037] The buffer assembly includes a movable seat 7, a buffer spring 9, and a support column 10. The bottom end of the movable seat 7 is fixedly installed with the buffer spring 9, and the bottom end of the buffer spring 9 is fixedly set on the inner bottom surface of the slot 8. The support column 10 is set inside the buffer spring 9 on the inner bottom surface of the slot 8. The top surface of the support column 10 and the bottom surface of the movable seat 7 press against each other. The buffer spring 9 is fixedly installed with the bottom surface of the movable seat 7. The buffer spring 9 buffers the pressing pressure when the fixed rod 5 is inserted into the slot 8, so as to avoid the bottom surface of the fixed rod 5 from hitting the support column 10 and causing damage to the upper stamping die 3.

[0038] A PLC controller 4 is installed on the upper side wall of the stamping machine body 1. The PLC controller 4 is model XD2-16R-E. The PLC controller 4 controls the telescopic rod 12 inside the stamping base 2 to control the stamping machine body 1.

[0039] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
