One side of the output shaft of the two electric push rods 6 is fixedly connected with a push plate 601, the top of the bottom plate 1 is fixedly connected with a support frame 7, one side of the support frame 7 is slidably connected with a plurality of sliders 8, the bottoms of the plurality of sliders 8 are rotatably connected with a connecting rod 9, the bottoms of the plurality of connecting rods 9 are rotatably connected with a moving plate 10, the bottom of the moving plate 10 is fixedly connected with two plug-in rods 11, and the bottoms of the two plug-in rods 11 are fixedly connected with an upper mold 12, and ventilation holes are provided on both sides of the lower mold 3 to assist the work of the air pump and avoid the generation of negative pressure, and a dustproof net is also provided inside the ventilation hole to prevent dust from entering.

[0025] Two motors 701 are fixedly connected to one side of the support frame 7, and a screw rod 702 is fixedly connected to one side of the output shaft of the two motors 701. The outer surfaces of the two screw rods 702 are respectively threadedly connected to the inside of the corresponding slider 8. When the two motors 701 are started, the output shafts of the two motors 701 rotate to drive the screw rods 702 to rotate, and the rotation of the screw rods 702 drives several sliders 8 to move.
