[0029] The principle of implementing the present invention is as follows: the control cylinder 2 is fixedly docked with the movable mold slide 7 through the fixed flange plate 201, which can realize the rapid disassembly of the movable mold slide 7, replacing the traditional fastener connection method; specifically, a circular array of matching holes is opened on the end face of the fixed flange plate 201, and the matching holes are docked with the matching shaft 701; a circular array of circumferential fixing holes 202 are opened on the circumference of the fixed flange plate 201, and the shaft fixing holes 702 are docked and matched through the fixed rod 1 25, and the circumferential fixing holes 202 are docked and matched through the fixed rod 26; further, through the operation of the fixed motor 19, under the gear transmission, the drive ring gear 27 is driven to rotate, and then the fixed slide 24 is moved, so that the fixed rod 1 25 is docked and matched with the shaft fixing hole 702, and the fixed rod 26 is docked and matched with the circumferential fixing hole 202. Further, the fixed outer cylinder 29 is controlled to dock with the fixed end shaft 2701 through the fixed oil cylinder 28 to fix the drive ring gear 27 and ensure the stability of the fixed state.

[0030] The control cylinder 2 drives the movable mold slide 7 to move up and down to complete the operation; during the operation, in order to prevent operational accidents, for example, when the upper and lower molds are close, the human body part is not yet located between the upper and lower molds, when the movable mold slide 7 descends, the movable mold slide 7 moves, and under the gear transmission, the driving gear 18 rotates, so that the rotating shaft 13 rotates, and then the turntable 11 and the protective push rod 12 rotate, and the protective push rod 12 pushes the protective plate 9 and the protective rod 8, and the protective rod 8 moves upward to contact the human body part, which has a contact warning effect.

[0031] Furthermore, when the upper and lower molds of the movable mold slide 7 are separated, under the connecting action of the connecting rod 16, the piston inner plate 1501 slides inside the connected outer cylinder 15, that is, compressed air is released through the air flow box 14, and the air flow box 14 sprays the air flow to the surface of the lower mold to complete the blowing of impurities, that is, to remove the impurity particles.

[0032] When in use, oil, such as lubricating oil, will be coated on the guide rod 5 to play a role in friction protection; after a long period of use, the oil on the surface of the guide rod 5 needs to be cleaned and replaced; specifically, in this embodiment, when cleaning the oil, the maintenance control electric cylinder 30 controls the movement of the maintenance control push rod 31, and the maintenance control push rod 31 pushes the pushing part 35 to move the outer docking frame 32, and the two outer docking frames 32 are docked, and then the outer ring 33 and the maintenance swivel 34 are docked to form a complete ring, and the maintenance swivel 34 surrounds the guide rod 5, and the maintenance drive motor 38 works. Under gear transmission, the maintenance swivel 34 rotates (when the maintenance swivel 34 is not working, the electromagnetic fixing rod 3301 presses and fixes the maintenance swivel 34); the oil on the surface of the guide rod 5 is cleaned by the cleaning part inside the maintenance swivel 34, and then the oil can be transmitted through the transmission box 3, that is, the surface of the guide rod 5 is sprayed by the spraying part 4.
