[0025] Wherein, the inside of first pair of die column 1 top end and the inside of second pair of die column 4 are equipped with through hole 14, the number of through hole 14 is two, the inner diameter size of two through holes 14 is same;Through the setting of through hole 14, operator can assemble tool, the inner surface of through hole 14 is smooth, so that assembly can be more smoothly.

[0026] Wherein, the inside of through hole 14 is movably sleeved with mounting rod 15, the number of mounting rod 15 is two, the outer end of two mounting rods 15 is fixedly connected with round block 16, the outer surface of round block 16 is movably connected with second pair of die column 4 and first pair of die column 1 respectively;Through the setting of round block 16, round block 16 can limit mounting rod 15, avoid mounting rod 15 to fall into the depth of through hole 14 inside.

[0027] Wherein, the number of round block 16 is two, the outer surface of two round blocks 16 is fixedly connected with guide needle 17 located above first pair of die column 1 and guide needle 18 located below second pair of die column 4 respectively;Operator inserts guide needle 18 into mould tool edge, and guide needle 17 is aligned with clamp punch hole, so that clamp punch can be fixed by lower mould hole position.

[0028] The outer surface of the circular block 16 is movably sleeved with a locking ring 19, and the outer surface of the locking ring 19 is movably connected with the first pair of mold columns 1 and the second pair of mold columns 4 respectively. By arranging the locking ring 19, the locking ring 19 can be fixed on the outer surface of the circular block 16 after being tightened, so that the circular block 16 can be fixed after the locking ring 19 is fixed.

[0029] The left side of the locking ring 19 is provided with a first bolt hole 20, and the left side of the locking ring 19 is provided with a locking cavity 21. The operator inserts the bolt into the first bolt hole 20, and then rotates and locks the bolt, so that the space of the locking cavity 21 is reduced, thereby locking the circular block 16.

[0030] The number of the locking ring 19 is two, and the second bolt hole 22 is arranged in the inside of the two locking rings 19. The operator inserts the bolt into the inside of the first pair of mold columns 1 and the inside of the second pair of mold columns 4 through the second bolt hole 22, and then locks the bolt, so that the locking ring 19 can be fixed with the first pair of mold columns 1 and the second pair of mold columns 4 respectively, thereby fixing the whole guide needle 17 and the whole guide needle 18.

[0031] The working principle and use process of the utility model are as follows:

[0032] Firstly, the operator inserts two installation rods 15 into the inside of the through hole 14, so that the guide needle 17 is above the first pair of mold columns 1 and the guide needle 18 is below the second pair of mold columns 4, and then inserts the guide needle 18 into the lower mold knife opening, so that the guide needle 17 is aligned with the clamp plate punch hole, thereby realizing the fixation of the clamp plate opening by taking the lower mold hole as the reference, when it is necessary to adjust the length of the first pair of mold columns 1 as a whole, at this time, the first pair of mold columns 1 can be pulled upwards, so that the clamping block 10 is driven upwards, when the inclined surface of the clamping block 10 contacts the inclined surface of the tooth plate 5, the clamping block 10 will be squeezed and pushed into the inside of the first pair of mold columns 1, so that the first pair of mold columns 1 can be smoothly lifted, when the first pair of mold columns 1 stops rising, at this time, the first spring 9 will push the clamping block 10 back to the original position under the action of the elastic force, so that the clamping block 10 is clamped with the tooth plate 5, thereby preventing the first pair of mold columns 1 from descending, so that the length of the first pair of mold columns 1 and the second pair of mold columns 4 as a whole can be extended, when the use is completed, the clamping block 10 can be inserted into the inside of the upper slot 6 by continuing to pull the first pair of mold columns 1 upwards, and then the first pair of mold columns 1 is rotated, so that the clamping block 10 is inserted into the vertical slot 7, at this time, the first pair of mold columns 1 can be pressed downwards, so that the clamping block 10 moves downwards in the vertical slot 7, when the clamping block 10 moves to the bottom of the vertical slot 7, the first pair of mold columns 1 is reversed, so that the clamping block 10 is reset along the inner surface of the lower slot 8, at this time, the second spring 11 will push the vertical rod 13 into the inside of the second pair of mold columns 4 under the action of the elastic force, so that the first pair of mold columns 1 and the second pair of mold columns 4 cannot rotate, thereby restoring the first pair of mold columns 1 as a whole.
