The slide groove 11 limits the moving trajectory of the slide bar 211 and prevents the slide bar 211 from moving downward and leaving the slide groove 11 due to its own weight; the lower ends of the bolts 213 threadedly connected to the four corners on the upper side of the mold body 1 are threadedly connected to the upper corners of the slide bar 211, so that the plastic plate 21 can be disassembled and assembled by loosening the bolts 213, and the symmetrically damaged plastic plate 21 can be replaced conveniently;

[0027] The lower side wall of the plastic plate 21 is provided with anti-skid patterns 212 at equal intervals. The anti-skid patterns 212 effectively increase the friction between the plastic plate 21 and the leather, thereby improving the stability of the bottom-cut leather cutting mold when placed on the leather, and facilitating the cutting of the leather according to the shape of the bottom-cut leather cutting mold.

[0028] When the above arrangement is used, the staff loosens the bolt 213 clockwise, that is, the bolt 213 is not threadedly connected to the slide rod 211, and applies external force to the plastic plate 21, so that the slide rod 211 gradually moves out of the slide groove 11, and the plastic plate 21 gradually moves away from the mold body 1, until the slide rod 211 is completely moved out of the slide groove 11, and the plastic plate 21 is completely separated from the mold body 1, that is, the disassembly of the plastic plate 21 is completed; otherwise, the plastic plate 21 is placed on the lower side of the mold body 1.

[0031] The third rectangular groove 14 is symmetrically provided with first anti-skid pads 141 on the upper and lower inner side walls. The sum of the thickness of the two first anti-skid pads 141 and the thickness of the first splicing joint 31 is equal to the inner width of the third rectangular groove 14. The first anti-skid pads 141 effectively increase the stability of the first splicing joint 31 inside the third rectangular groove 14, and improve the stability of the first splicing joint 31 after being plugged into the mold body 1.

[0032] Among them Figure 1 , 3 As shown in Figure 4, a second anti-slip ring 323 is provided on the inner wall of the second slot 321. The inner depth dimension of the second slot 321 is half of the length dimension of the second joint 32. The inner depth dimension of the second slot 321 is equal to the length dimension of the second plug-in block 34.

[0034] When the above arrangement is used, the staff applies an external force to the first joint 31 on one mold body 1, and the first joint 31 moves in an arc with the first damping hinge 312 as a fixed point until the first joint 31 rotates 90 degrees. The staff aligns the first slot 311 with the first plug block 33 on the other mold body 1. The staff applies an external force in opposite directions to one mold body 1 and the other mold body 1, and the first plug block 33 is plugged into the first slot 311 until one mold body 1 and the other mold body 1 are in contact. The first plug block 33 is completely inserted into the first slot 311, and the connection between the two adjacent lower-cut leather cutting molds is completed. Splicing; or, the staff applies external force to the second splicing joint 32 on one mold body 1, and the second splicing joint 32 moves in an arc with the second damping hinge 322 as a fixed point until the second splicing joint 32 rotates ninety degrees, and the staff aligns the second slot 321 with the second plug block 34 on the other mold body 1, and the staff applies opposite external forces to one mold body 1 and the other mold body 1, and the second plug block 34 is plugged into the second slot 321 until one mold body 1 and the other mold body 1 are in contact, and the second plug block 34 is completely inserted into the second slot 321, completing the splicing between the two adjacent down-cut leather cutting molds.
