Publication No. CN213079791U discloses a stamping die frame, including a machine base, a lower die base arranged on the machine base, and an upper die base slidably arranged on the machine base. The lower die base and the upper die base are both located between two base arms of the machine base. A mold core is detachably arranged on the lower die base, and the mold core is located directly below the upper die base. A conveying platform is arranged on the machine base, and the height of the horizontal plane where the top of the conveying platform is located is the same as the height of the horizontal plane where the top of the mold core is located. A conveying platform is arranged on any one of the base arms of the machine base. There is a linear module, the slide of the linear module is connected to the connecting plate and can drive it to slide left and right, the free end of the connecting plate is provided with a push plate and the push plate is located between the two seat arms of the machine base. The purpose of the utility model is to provide a stamping die frame that can automatically load materials. Although the product can automatically load materials, it is not convenient to automatically eject the formed workpiece, which can easily cause the workpiece to be stuck inside the lower mold after the stamping is completed, and workers are required to use the workpiece to take out the workpiece inside, which makes the workpiece easy to be worn by the workpiece and makes it more cumbersome to take out, reducing the efficiency of the connection stamping, and the practicality is poor, and needs to be improved.

[0024] Embodiment 2

[0025] See also Figure 1-3 5. A protective plate 13 is slidably connected to the surface of the fixed rod 2 to protect the workers. An observation window 14 is provided on the surface of the protective plate 13 to facilitate observation of the stamping situation. A limiting rod 15 is slidably connected inside the protective plate 13 to allow the protective plate 13 to be clamped and fixed at a suitable position. A push plate 16 is fixedly installed at one end of the limiting rod 15 to facilitate pulling the limiting rod 15. A spring B17 is fixedly installed on the side of the push plate 16 to automatically restore the push plate 16 and the limiting rod 15.
