[0020] The present invention is further described in detail below in conjunction with the accompanying drawings. In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "upper, lower" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0021] like Figure 1-5 As shown, a cardboard stamping and forming device for paper box production comprises a base 1, a lower die seat 3 is fixedly mounted on the base through a foot 2, a top seat is fixedly mounted on the lower die seat upward through a guide rod 4, a lifting cylinder 6 is fixedly mounted on the top seat, a cylinder rod of the lifting cylinder passes through the top seat and an upper die seat 7 is fixedly mounted downward, the upper die seat is arranged directly above the lower die seat, and the upper die seat and the lower die seat are respectively connected to an upper die 8 and a lower die 9 through a quick connection structure;

[0022] The quick connection structure is provided with two groups, and each group of the quick connection structure includes two spaced sliders 11 fixedly installed on the mounting ends of the upper die and the lower die, and the upper die base and the lower die base are provided with slide grooves 12 that can slide with the sliders opposite to the sliders, and the upper die base and the lower die base are provided with locking grooves 13, and the locking grooves are located between the two slide grooves. Two locking plates 14 are provided in the locking grooves, and two locking pins 15 are fixed on the locking plates. The locking pins horizontally pass through the upper die base and the lower die base and extend into the slide grooves, and the slider is provided with a locking hole 16 that can be plugged and matched with the locking pin, and the upper die base and the lower die base are installed with a power structure for driving the two locking plates to move synchronously.

[0023] In this way, the upper die is connected to the upper die seat through a quick connection structure, and the lower die is connected to the lower die seat through a quick connection structure. When connecting, the sliders of the upper die and the lower die are inserted into the slide groove, and the power mechanism drives the locking plate to move synchronously, so that the locking pin passes horizontally through the upper die seat and the lower die seat and is inserted into the locking hole of the slider to complete the installation. When disassembly is required, the power structure can be reversed. There are two sets of quick connection structures to improve the connection stability.

[0024] During implementation, the power structure includes a transmission gear 17, and the transmission gear is fixed with a wheel axle, and the wheel axle is rotatably connected to the upper die base and the lower die base respectively. The two locking plates are fixed with racks 18 and the two racks are meshed with the opposite sides of the gear. The end of the gear shaft passes through the upper die base or the lower die base and is fixed with an upper bevel gear 21. A servo motor 22 is fixedly installed on the upper die base and the lower die base through a motor bracket. The output shaft of the servo motor is fixed with a rotating shaft 23, and the rotating shaft is fixed with a driving bevel gear 24. A transmission shaft 25 is rotatably installed on the upper die base and the lower die base through a bracket. A driven bevel gear 26 meshing with the driving bevel gear is fixed on the transmission shaft. End bevel gears 27 meshing with the upper bevel gear are fixedly installed at both ends of the transmission shaft.

[0025] In this way, the servo motor drives the active bevel gear to rotate, the active bevel gear drives the driven bevel gear, the transmission shaft and the end bevel gear to rotate, and the end bevel gear drives the upper bevel gear, the gear shaft and the gear to rotate. Since the racks are arranged on both sides of the gear, during the rotation of the gear, the locking plate will be driven to move outward through the two racks, thereby driving the locking pin to be inserted into the locking hole to complete the locking.

[0026] During implementation, the mounting ends of the upper and lower dies are fixed with a plurality of dovetail blocks 28, and the upper and lower die bases are provided with dovetail grooves 29 that slide with the dovetail blocks, so as to provide a mounting base for the upper and lower dies and improve the mounting stability.
