[0024] It includes a die-cutting board 1, a cutter body 6 and a mounting tube 9, wherein a No. 1 spring 10 is arranged inside the mounting tube 9, a moving column 11 is arranged at the top end of the No. 1 spring 10, and the moving column 11 is movably engaged and located inside the mounting tube 9, a positioning frame 14 is arranged at the top end of the moving column 11, and the height of the positioning frame 14 is greater than the cutter body 6, a No. 1 threaded tube 12 is arranged on the top of the die-cutting board 1, and the No. 1 threaded tube 12 is threadedly connected to the mounting tube 9, a No. 2 threaded tube 13 is arranged at the bottom end of the positioning frame 14, and the No. 2 threaded tube 13 is threadedly connected to the moving column 11.

[0025] The outer part of the mounting tube 9 is threadedly connected with the No. 1 threaded tube 12, so that the mounting tube 9 can be assembled and arranged inside the mounting hole 3, which is convenient for assembling and disassembling the mounting tube 9 at a later time. The movable column 11 is movably arranged inside the mounting tube 9 by the No. 1 spring 10, and the mounting tube 9 can move the movable column 11 up and down. By utilizing the elastic effect of the No. 1 spring 10, the No. 1 spring 10 can push the movable column 11 to move upward inside the mounting tube 9. The positioning frame 14 arranged on the top of the movable column 11 is higher than the cutter body 6 after installation. When the die-cutting board 1 drives the installed cutter body 6 to move down to cut the cardboard, the positioning frame 14 can first contact and squeeze the cardboard. As the die-cutting board 1 moves downward, the movable column 11 can move toward the inside of the mounting tube 9, squeeze the No. 1 spring 10 to deform, and the positioning frame 14 is moved down to the cutter body 6 to cut the cardboard. The positioning frame 14 is used to pre-extrude and position the cardboard to be cut, which can improve the accuracy of the blade when pressing down to cut the cardboard, and effectively improve the cutting quality of the finished product.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a positioning cardboard die-cutting die with high processing accuracy;

[0027] A No. 1 mounting groove 2 is provided on the top of the die-cutting board 1, and a cutter body 6 is movably arranged inside the No. 1 mounting groove 2.

The guide rod 18 is used to movably engage with the limiting cylinder 17, and then the limiting cylinder 17 is connected to the inside of the blocking plate 15. The through hole 16 opened inside the blocking plate 15 can penetrate the inside of the limiting cylinder 17. By utilizing the elastic effect of the No. 2 spring 19, the No. 2 spring 19 can elastically push the blocking plate 15 to move inside the No. 3 mounting groove 5. The blocking plate 15 is used to block and limit the top of the combination plate 8 inside the No. 3 mounting groove 5, so as to facilitate the disassembly, assembly and replacement of the cutter body 6 at a later time.

[0032] When in use, the No. 1 mounting groove 2 provides an installation space for the cutter body 6. After the cutter body 6 is installed in the No. 1 mounting groove 2, the four groups of combined plates 8 arranged outside the cutter body 6 can be installed in the No. 3 mounting groove 5, and connected and installed in the cutter body 6 by the reinforcing plate 7. The reinforcing plate 7 can increase the overall strength of the cutter body 6, and avoid the contour cutter body 6 from expanding and deforming outwards due to excessive die-cutting pressure, and incomplete cutting of the cardboard;

[0033] The blocking plate 15 can be movably arranged inside the No. 2 mounting groove 4 by using the guide rod 18, and one end of the guide rod 18 can be limited by using the limiting cylinder 17, so that the blocking plate 15 and the guide rod 18 are movably connected, and the No. 2 spring 19 can elastically push the blocking plate 15 to move inside the No. 3 mounting groove 5, and the blocking plate 15 is used to block and limit the top of the combination plate 8 inside the No. 3 mounting groove 5, so as to facilitate the disassembly and replacement of the cutter body 6 in the later stage;

[0034] When the die-cutting board 1 drives the installed cutter body 6 to move downward to cut the cardboard, the positioning frame 14 can first contact and squeeze the cardboard. As the die-cutting board 1 moves downward, the movable column 11 can move toward the inside of the installation tube 9, squeezing and deforming the No. 1 spring 10. The positioning frame 14 moves down to the cutter body 6 to cut the cardboard. The positioning frame 14 is used to pre-extrude and position the cardboard to be cut, which can improve the accuracy of the blade when pressing down to cut the cardboard, and effectively improve the cutting quality of the finished product.
