[0033] Further comprising a waste hole 11 corresponding to the punch 5, and the waste hole 11 penetrates the fixed seat 6, the lower die plate 7 and the placement plate 9, and the waste hole 11 penetrating the fixed seat 6, the lower die plate 7 and the placement plate 9 can drop the waste left after punching to the bottom of the mold, which is convenient for the operator to handle regularly;
[0034] The lower die plate 7 is provided with a first guide slot 12 on both sides, and the two first guide slots 12 correspond to the lower ends of the placement plate 9 on both sides, and the first guide slot 12 extends into the fixed seat 6, and the fixed seat 6 is provided with a second guide slot 13 on both sides, and the two second guide slots 13 are communicated with the two first guide slots 12 respectively;
[0035] The first guide slot 12 is provided with a moving rod 14 inside, the upper end of the moving rod 14 protrudes out of the first guide slot 12 and is connected with the placement plate 9, and the lower end of the moving rod 14 has a first inclined surface 15 towards one side of the second guide slot 13, the second guide slot 13 is provided with a transmission rod 16 inside, the transmission rod 16 has a second inclined surface 17 towards one side of the first guide slot 12, and the second inclined surface 17 is in abutting fit with the first inclined surface 15, the lower end of the upper die plate 4 is connected with a long rod 18 on both sides, the lower end of the long rod 18 is bent by 90° twice to form a pushing rod 19 towards one side of the fixed seat 6, the upper end of the pushing rod 19 has a third inclined surface 20, the side of the transmission rod 16 away from the first guide slot 12 protrudes out of the fixed seat 6 and forms a fourth inclined surface 21, and the fourth inclined surface 21 is in abutting fit with the third inclined surface 20;
[0036] Among them, the inclination angles of the first inclined surface 15, the second inclined surface 17, the third inclined surface 20 and the fourth inclined surface 21 are the same;
[0037] Specifically, when the upper die plate 4 is lifted and the lower die plate 7 is opened, the long rods 18 on both sides are lifted with the upper die plate 4, and the third inclined surface 20 at the top of the pushing rod 19 is in abutment with the fourth inclined surface 21 of the transmission rod 16 during the lifting process, and gradually contacts and interacts, so that the lifting movement of the pushing rod 19 is gradually converted into the power for pushing the transmission rod 16 to translate into the second guide slot 13. During the translation of the transmission rod 16, the second inclined surface 17 is in abutment with the first inclined surface 15 at the lower end of the moving rod 14, and gradually contacts and interacts, so that the translation of the transmission rod 16 is converted into the power for pushing the moving rod 14 to lift. The moving rod 14 protrudes from the top of the lower die plate 7 and is connected with the placement plate 9, so that the placement plate 9 is lifted by the moving rod 14, and the placement plate 9 and the workpiece are away from the lower die plate 7, so that the operator can easily take the workpiece after punching, and the problem of inconvenient taking of the workpiece during the machining of the thin workpiece is solved.
[0038] The length and width of the first guide slot 12 should be consistent with the moving rod 14, so that the moving rod 14 can move vertically. The length and width of the second guide slot 13 should be consistent with the transmission rod 16, so that the transmission rod 16 can translate linearly, thereby ensuring the accuracy of the movement trajectory and avoiding the deviation and skew of the moving rod 14 and the transmission rod 16 during the movement, so as to improve the effectiveness of the power conversion between them and make the movement more smooth.
[0039] In this embodiment, referring to Figure 6 , the placement plate 9 is further provided with a workpiece placement slot 28, and the edge of the placement plate 9 is further provided with a taking notch 29.
[0040] Further, after the placement plate 9 is lifted by the moving rod 14, the operator can use the taking notch 29 of the placement plate 9 to quickly and conveniently hold and take the workpiece, and the workpiece placement slot 28 is used for positioning the workpiece.
[0041] In this embodiment, referring to Figure 3 and Figure 5 , the second guide slot 13 is further provided with a movable slot 22 at the inner bottom surface, the transmission rod 16 is provided with a movable block 23 slidingly arranged in the movable slot 22 at the lower end, and a return spring 24 is arranged between the side surface of the movable block facing the first guide slot 12 and the inner wall of the movable slot 22.

[0042] When the workpiece after punching is taken out and the next workpiece is placed on the placing plate 9 for punching again, the hydraulic cylinder 10 drives the upper die plate 4 to move downward, and the long rod 18 and the push rod 19 move downward, so that the third inclined surface 20 of the push rod 19 is separated from the fourth inclined surface 21 of the transmission rod 16, so that the transmission rod 16 is not pushed by the push rod 19. At this time, the reset spring 24 inside the movable groove 22 pushes the movable block 23 by using the elastic potential energy stored in advance, and drives the transmission rod 16 to move away from the first guide groove 12 to reset, so that the second inclined surface 17 is separated from the first inclined surface 15, that is, the moving rod 14 can move downward to reset by relying on its own gravity, so that the placing plate 9 moves into the annular groove 8. It should be noted that the downward stroke of the upper die plate 4 and the punch 5 is greater than that of the placing plate 9, so that when the placing plate 9 is completely moved into the annular groove 8, the upper die plate 4 and the punch 5 are still in the process of moving downward, so that the punch 5 does not collide with the placing plate 9 which is still in the air, and the placing plate 9 is damaged by frequent collision with the lower die plate 7 after being impacted by the punch 5. Therefore, no additional power mechanism is needed, and the placing plate 9 can automatically lift and move downward following the opening and closing of the upper die plate 4 and the lower die plate 7.

[0045] Preferably, the limiting seat 25 is arranged on both sides of the lower die seat 2, and the limiting groove 26 is formed in the limiting seat 25 to guide and limit the transmission rod 16 which protrudes from the fixed seat 6, so as to guide and limit the movement track of the external transmission rod 16, avoid the transmission rod 16 from being warped when the push rod 19 pushes the transmission rod 16, and provide a channel for the upward movement of the push rod 19 through the through opening 27 to avoid the movement conflict with the push rod 19.
[0046] In the embodiment, referring to Figure 4 , it is further proposed that the annular groove 8 is provided with a buffer ring 30.
[0047] Preferably, the buffer ring 30 arranged on the annular groove 8 is made of a material which can absorb impact force, such as silica gel or rubber. When the placing plate 9 moves into the annular groove 8, the buffer ring 30 can absorb the vibration generated when the placing plate 9 collides with the bottom surface of the annular groove 8, avoid the vibration of the placing plate 9 caused by the vibration of the workpiece placed thereon, and further ensure the stability of the workpiece, reduce the defective rate and improve the processing quality.
[0048] In the embodiment, reference is made to Figure 1 Further, the lower die seat 2 is provided with a clearance slot 31 corresponding to the two long rods 18 on both sides;
[0049] Preferably, the clearance slot 31 is provided mainly to provide space for the up-and-down movement of the long rod 18 and the push rod 19, and also to limit the moving direction of the long rod 18, so that the long rod 18 keeps straight movement when moving.
