One end of the second screw rod 16 is connected to the second screw motor 12. The second screw motor 12 is fixed in the second screw motor seat 8. The second screw motor seat 8 is arranged on one side of the bracket 5.
[0019] The crossbeam 6 is provided with a long groove for avoiding the cylinder rod.
[0020] A guide plate 7 is fixed on the bracket 5 just below the crossbeam 6 . The guide plate 7 is parallel to the crossbeam 6 . A guide groove for avoiding the cylinder rod is provided on the guide plate 6 .
[0021] The slide 2 is fixed to the base 1 through the column 3 . The slide 2 is provided with two slide grooves 11 which are parallel to each other and perpendicular to the crossbeam 6 . There are two lower molds 14 which slide in the slide grooves 11 of the two slides 2 respectively.
[0022] Below the slide 2, two sets of linear actuators are provided on the base 1, which are parallel to each other and perpendicular to the crossbeam 6; the two lower molds 14 are respectively controlled by two linear actuators to slide along the slide grooves 11.
[0023] The linear actuator is a screw slide system, including a first screw motor seat 4, a first screw motor 12, a first screw 13, and a screw shaft seat 10; the first screw motor 12 is fixed in the first screw motor seat 4, and the first screw motor seat 4 and the screw shaft seat 10 are fixed on the base 1; the rotating shaft of the first screw motor 12 is connected to the first screw 13, and the end of the first screw 13 passes through the screw shaft seat 10; the first screw 13 drives the lower mold 14 to move.
[0024] A rotating cylinder seat 9 is provided on one side of the base 1, and a rotating cylinder 20 is placed in the rotating cylinder seat 9.

[0025] Directions:
[0026] The two linear actuators each control a lower die 14. When the first lower die 14 is located directly below the upper die 19, the other lower die 14 is located near the demolding rod 21. After the stamping operation is completed at the first lower die 14, the linear actuator drives the first lower die 14 to a position close to the demolding rod 21. The support shafts of the demolding rods 21 extend into both sides of the first lower die 14, just in the positive direction of the left and right ends of the residual material in the mold. The main shaft of the demolding rod 21 is driven by the rotating cylinder 20 to rotate, so that the support shafts of the demolding rods 21 lift the residual material at both ends of the mold, thus achieving demolding. At the same time, the other lower die 14 moves to just below the crossbeam 6, and the cylinder slide 17 moves to just above the other lower die 14. At this time, the upper die 19 is located just above the other lower die 14, and the mold material in the other lower die 14 is stamped. The above process is repeated, one lower die 14 is performing the stamping operation, and the other lower die 14 is performing the demoulding process. The stamping and demoulding processes of the mold materials in the two lower dies 14 are performed alternately and without interfering with each other, which greatly improves work efficiency.
