[0015] In this embodiment, combined with the Figure 2 and attached Figure 3 As shown, the safe material removal lower mold structure 6 includes a workbench 601, and the left and right sides of the upper middle part of the workbench 601 are fixedly connected with guide rails 602, and the upper sides of the guide rails 602 are slidably provided with sliders 603, wherein a movable plate 604 is fixedly connected to the upper part between the sliders 603; the upper middle part of the movable plate 604 is fixedly connected with the lower mold 605; the lower middle part of the movable plate 604 is fixedly connected with a connecting block 606, and the inner middle part of the connecting block 606 is provided with a mounting hole, wherein a ball nut is fixedly connected inside the mounting hole; the upper middle part of the workbench 601 is fixedly connected with a U-shaped mounting seat 607, and the upper middle bearing inside the U-shaped mounting seat 607 is connected with a screw 608, wherein the screw 608 is threadedly connected inside the ball nut; the upper opening at the rear of the U-shaped mounting seat 607 is fixedly connected with a driving motor 609, and the front end of the output shaft of the driving motor 609 is connected to the rear end of the screw 608 by a coupling.

[0016] In the present embodiment, specifically, the second hydraulic cylinder 610 is fixedly connected to the left and right sides of the lower middle part of the workbench 601, and the upper end of the second hydraulic cylinder 610 passes through the interior of the workbench 601, wherein the upper end of the output rod of the second hydraulic cylinder 610 is fixedly connected to the push plate 611; the push plate 611 is respectively located between the guide rail 602 and the U-shaped mounting seat 607; the upper part of the push plate 611 is respectively pressed against the lower part of the movable plate 604.

[0017] In this embodiment, specifically, the upper four corners of the workbench 601 are respectively fixedly connected to the lower end of the guide rod 2 .

During the forward movement of the movable plate 604, the slider 603 will slide on the upper side of the guide rail 602 until the lower mold 605 is completely offset from the upper mold 5. At this time, the operator can place the metal material or take the metal material, and the operator's hand will not be located between the two molds, thereby achieving the effect of safe material taking and discharging; because the drive motor 609 is a servo motor, the number of rotations of the screw 608 can be accurately controlled by the drive motor 609, and then the moving distance of the lower mold 605 can be accurately controlled, thereby avoiding the problem that the lower mold 605 and the upper mold 5 cannot be closed after the lower mold 605 is reset, thereby achieving the effect of precise processing.

[0023] When performing stamping, the operator can control the start of the second hydraulic cylinder 610 through the external hydraulic transmission system, so that the second hydraulic cylinder 610 drives the push plate 611 to move upward until the push plate 611 is pressed against the lower part of the movable plate 604. At this time, the movable plate 604 can be auxiliary supported by the push plate 611 and the second hydraulic cylinder 610, so as to avoid the problem that all the pressure acts on the guide rail 602 and the slider 603 during stamping, thereby avoiding the problem of damage to the guide rail 602 and the slider 603. After the stamping is completed, the operator can control the start of the second hydraulic cylinder 610 through the hydraulic transmission system, so that the second hydraulic cylinder 610 drives the push plate 611 to move downward, thereby separating the push plate 611 from the movable plate 604.
