[0022] In one embodiment, as shown in Figures 1-6 a long and short floor shared trimming die, comprising a lower die seat 1 and an upper die seat 2 located directly above the lower die seat 1, the lower die seat 1 is fixed with a discharge inclined plate 18 symmetrically on both sides, a plurality of long piece waste cutters 11, a short piece waste cutter 12 and two long and short piece shared waste cutters 13 are arranged on the lower die seat 1, the short piece waste cutter 12 is located between the two long and short piece shared waste cutters 13, the long piece waste cutter 11 is located on the left side of the short piece waste cutter 12 and the long and short piece shared waste cutter 13, a plurality of long piece trimming cutter blocks 21 and a movable short piece trimming cutter block 22 are arranged on the upper die seat 2, the long piece trimming cutter block 21 is located on the left side of the movable short piece trimming cutter block 22, the long piece trimming cutter block 21 corresponds to the long piece waste cutter 11, the movable short piece trimming cutter block 22 corresponds to the short piece waste cutter 12 and the long and short piece shared waste cutter 13, the long and short piece shared waste cutter 13 is provided with an auxiliary throwing material block 14 on one side, the lower end of the auxiliary throwing material block 14 is fixed with the telescopic end of a cylinder one 141, and the cylinder one 141 is installed on the lower die seat 1.

[0023] In this embodiment, when producing a long piece of floor, first, when producing a long piece of floor, the floor long piece to be processed is accurately placed on the lower die seat 1, and the alignment of the long piece waste cutter 11 and the long piece trimming cutter block 21 is ensured. Start the die, and the upper die seat 2 starts to move downward. The long piece trimming cutter block 21 contacts the edge of the floor long piece and performs accurate trimming operation. As the upper die seat 2 continues to press down, the long piece waste cutter 11 will cut off the excess edge material, and these waste materials will then slide through the discharge inclined plate 18 for collection and processing. After trimming is completed, the upper die seat 2 will rise back to the initial position to prepare for the next operation.

[0024] In this process, the movable short piece trimming cutter block 22 and the auxiliary throwing material block 14 (controlled by the cylinder one 141) do not participate in the production of the floor long piece.

[0025] In the production of floor short pieces, the floor short piece to be processed is placed accurately on the lower die seat 1, ensuring its alignment with the movable short piece trimming blade 22 and the long short piece shared waste material cutter 13. Start the mold, and the upper die seat 2 starts to move downward. The movable short piece trimming blade 22 contacts the edge of the floor short piece and performs accurate trimming. As the upper die seat 2 continues to press down, the movable short piece trimming blade 22 and the long short piece shared waste material cutter 13 cut off the excess edge material. The auxiliary ejection block 14 controlled by the cylinder 141 works to ensure that the waste material can slide down through the discharge chute 18 for collection and processing.

[0026] In an optional embodiment, a nitrogen gas spring 151 is installed on the lower die seat 1, with the upper end of the nitrogen gas spring 151 connected to the movable blade edge 15 located on one side of the auxiliary ejection block 14, and the movable blade edge 15 corresponding to the position of the movable short piece trimming blade 22.

[0027] It should be noted that the nitrogen gas spring 151 not only provides stable and controllable elastic force, enabling the movable blade edge 15 to maintain the best working state during trimming, but also effectively reduces mechanical wear and tear, prolonging the service life of the mold. In the production of floor short pieces, the movable short piece trimming blade 22 will compress the movable blade edge 15, so that the waste material is not cut into two ends, and at this time the center of gravity of the waste material is located outside the movable blade edge 15, and the waste material has a tendency to slide outwards. Then, the auxiliary ejection block 14 controlled by the cylinder 141 works to ensure that the waste material can slide down through the discharge chute 18 for collection and processing.

[0028] In an optional embodiment, the upper end of the movable short piece trimming blade 22 is fixed with a base 26, and the upper end of the base 26 is fixed with the telescopic end of a cylinder 27.

[0030] It should be noted that in order to ensure the safety of the base 26 during operation, a cylinder three 281 is installed on the upper die holder 2, and its telescopic end is fixed with a safety pin 28. When it is necessary to fix the base 26, the cylinder three 281 will drive the safety pin 28 to insert into the corresponding position of the base 26, thereby effectively preventing it from moving or falling off during operation. A manual valve 23 is provided on the upper die holder 2 for switching the working state of the cylinder three 281 and the cylinder four 291, so that the switching between safety locking and support can be easily realized according to actual needs, greatly improving the operation efficiency and flexibility.

[0031] In an optional embodiment, a plurality of large molds 16 and small molds 17 are fixed on the lower die holder 1, and a plurality of large pressing cores 24 and small pressing cores 25 are provided on the upper die holder 2, each large pressing core 24 corresponding to a large mold 16, and each small pressing core 25 corresponding to a small mold 17.

[0032] It should be noted that when producing long pieces, the large pressing core 24 and the small pressing core 25 work simultaneously to press the material, and the outer long piece trimming cutter block 21 works to realize the production of long pieces. When producing short pieces, the large pressing core 24 works to press the material, and the small pressing core 25 is only empty and does not work.

[0033] The above embodiment discloses a long and short floor shared trimming die, wherein when producing long floor pieces, the manual valve 23 is first switched, the support block 29 controlled by the cylinder four 291 is withdrawn, the base 26 and the movable short piece trimming cutter block 22 controlled by the cylinder two 27 are retracted, and the safety pin 28 controlled by the cylinder three 281 is extended, thereby ensuring that the movable short piece trimming cutter block 22 is retracted and does not work.

[0034] Subsequently, the floor long piece to be processed is accurately placed on the lower die holder 1, ensuring its alignment with the long piece waste cutter 11 and the long piece trimming cutter block 21. Start the die, and the upper die holder 2 starts to move downward. The large pressing core 24 and the small pressing core 25 work simultaneously to press the material, the long piece trimming cutter block 21 contacts the edge of the floor long piece, and accurate trimming operation is performed. With the continuous downward pressing of the upper die holder 2, the long piece waste cutter 11 will cut off the excess edge material, and the movable blade 15 will cut the waste into two sections, which will then slide through the discharge inclined plate 18 for collection and processing. After trimming is completed, the upper die holder 2 will rise back to the initial position, ready for the next operation.

[0035] When producing short floor pieces, the manual valve 23 is switched, the safety pin 28 controlled by the cylinder three 281 is retracted, the support block 29 controlled by the cylinder four 291 is extended, and the base 26 and the movable short piece trimming cutter block 22 controlled by the cylinder two 27 are extended.

[0036] Subsequently, the floor short piece to be processed is precisely placed on the lower die seat 1, ensuring its alignment with the movable short piece trimming cutter block 22 and the long short piece shared waste cutter 13. The mold is started, and the upper die seat 2 starts to move downward. The large pressing core 24 works to press the material, the movable short piece trimming cutter block 22 contacts the edge of the floor short piece, and precise trimming operation is performed. As the upper die seat 2 continues to press down, the movable short piece trimming cutter block 22 and the long short piece shared waste cutter 13 cut off the excess edge material. And the movable short piece trimming cutter block 22 will compress the movable blade edge 15, so as not to cut the waste into two ends, and then the auxiliary waste throwing block 14 controlled by the air cylinder 141 works, ensuring that the waste can slide down through the discharge inclined plate 18, so as to be collected and processed.
