Therefore, each time the die is stamped, it may be necessary to manually demould and adjust the position of the die, so it is difficult to make the stamping die work continuously. This production method, on the one hand, is likely to bring production safety hazards to workers, and on the other hand, it is also likely to reduce production efficiency, which is not conducive to large-scale production of stamping dies.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0019] Example 1

[0020] A stamping die that is easy to remove, such as Figure 1-6As shown, it includes a base 1, a pulley 2, a vertical plate 3, an air compressor 4, a connecting arm 5, a hammer 6, a rotating shaft 7, a rotating rod 8, a ratchet 9 and a rack 10. Four pulleys 2 are fixedly connected to the bottom of the base 1, and the four pulleys 2 are respectively located at the four corners of the bottom of the base 1. The base 1 is fixedly connected to the vertical plate 3. Two long square holes are opened on the vertical plate 3. The two long square holes are vertically arranged but not connected to each other. The air compressor 4 is fixedly placed on the base 1, and the connecting arm 5 is fixedly connected to the output shaft of the air compressor 4. The connecting arm 5 is located above the air compressor 4. The other end of the connecting arm 5 is fixedly connected to the hammer 6. The rotating shaft 7 is rotatably connected to the vertical plate 3, and the rotating rod 8 is fixedly connected to the rotating shaft 7. The rotating rod 8 is initially vertically arranged. The air compressor 4 and the rotating rod 8 are located on the same side of the vertical plate 3. The rotating shaft 7 passes through the other end of the vertical plate 3 and is fixedly connected to the ratchet 9. The rack 10 passes through one of the square holes of the vertical plate 3 and is fixedly connected to the connecting arm 5.

[0021] It also includes a retaining ring 11, a clamping block 12 and a reset spring 13. The retaining ring 11 is fixedly connected to the rotating shaft 7 and is in the shape of a hexagonal prism. The clamping block 12 is slidably connected to another square hole of the vertical plate 3. One end of the clamping block 12 has an opening, and the opening of the clamping block 12 is used to clamp the retaining ring 11. One end of the reset spring 13 is fixedly connected to the clamping block 12, and the other end of the reset spring 13 is fixedly connected to the vertical plate 3.

[0022] It also includes a cylinder 14, a pressure spring 15, a telescopic column 16 and a pushing groove plate 17. The cylinder 14 is fixedly connected to the block 12. One end of the pressure spring 15 is fixedly connected in the cylinder 14. The other end of the pressure spring 15 is fixedly connected to the telescopic column 16. The telescopic column 16 can slide in the cylinder 14 through the pressure spring 15. The side of the rack 10 away from the ratchet 9 is fixedly connected to the pushing groove plate 17, and the pushing groove plate 17 is provided with a card slot.

[0023] Usage: When making a stamping die, the staff first starts the air press 4, which will drive the connecting arm 5 to slide downward in the vertical square hole of the vertical plate 3, and the connecting arm 5 will drive the hammer 6 to move downward. When the hammer 6 moves downward to coincide with the top of the rotating rod 8, the stamping die begins. The connecting arm 5 will also drive the rack 10 to move downward, and the rack 10 will drive the pushing slot plate 17 to move up and down. When the rack 10 drives the pushing slot plate 17 to move downward, the pushing slot plate 17 will push the telescopic column 16 to move into the cylinder 14, and the telescopic column 16 will compress the pressure spring 15 into the cylinder 14, so that the telescopic column 16 can slide in the slot of the pushing slot plate 17. At the same time, when the rack 10 moves downward, the rack 10 has no effect on the ratchet 9. Influence, when the telescopic column 16 slides in the slot of the pushing slot plate 17, the block 12 will limit the retaining ring 11 under the push of the reset spring 13, and the retaining ring 11 can stabilize the rotating shaft 7, so that the rotating rod 8 on the rotating shaft 7 can be stably stamped in the vertical direction. When the mold is stamped, the mold will be bonded to one end of the rotating rod 8, and the air press 4 will drive the connecting arm 5 to move upward, and the connecting arm 5 drives the rack 10 to move upward, and the rack 10 drives the pushing slot plate 17 to move upward. The inclined surface at the upper end of the pushing slot plate 17 will have a thrust on the telescopic column 16, so that the telescopic column 16 will drive the card plate to compress the reset spring 13, so that the card plate is away from the retaining ring 11, so that the card plate no longer limits the retaining ring 11.

[0024] Example 2

[0025] On the basis of Example 1, Figure 1 , Figure 6 As shown, a heavy ring 18 is also included. A heavy ring 18 is provided on the upper and lower sides of the rotating shaft 7 respectively, and the heavy ring 18 is slidably connected to the rotating rod 8.

[0026] The air compressor 4 is vertically arranged and is located on the right side of the rotary rod 8 .

[0027] At the same time, the rack 10 will drive the ratchet 9 to rotate, the ratchet 9 will drive the shaft 7 to rotate, the shaft 7 will drive the rotary rod 8 to rotate 180 degrees, so that the end of the rotary rod 8 bonded with the mold will rotate downward to the lowest position, and the downward rotation of the rotary rod 8 will drive the heavy ring 18 to slide downward along the shaft 7, so that the heavy ring 18 has a downward impact force on the mold bonded to the rotary rod 8, so that the mold can be detached from the rotary rod 8. After the mold stamping is completed, the staff turns off the air press 4.

[0028] The above-mentioned embodiments only express the preferred implementation of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model.
