With the connection point between the forming die seat and the U-shaped seat as a reference, the bottom weight of the forming die seat is greater than the upper weight. After the forming cavity is filled with material, the upper weight of the forming die seat is greater than the lower weight. The starting position of the forming die seat is located on the upper side of the material guide plate. At this time, the forming cavity is not filled with material.

The upper rear side of the U-shaped seat 5 is fixedly connected to an electromagnet 6 that can adsorb and fix the forming die base 3. A downward pressing molding mechanism 7 is arranged at the inner top of the frame 2 and is used to cooperate with the molding cavity 301 of the molding die base 3 to extrude and mold the material entering the molding cavity 301; The material discharge mechanism 8 comprises a storage hopper 801 arranged on the frame 2 outside the downward pressure forming mechanism 7, and the bottom side of the storage hopper 801 is respectively provided with a discharge pipe 802 adapted to the forming cavity 301, and the discharge pipe 802 is respectively fixedly installed with a corresponding discharge valve 9; The material guide plate 10 is arranged on the front side of the workbench 1 at an angle downward. With the connection point between the forming die base 3 and the U-shaped base 5 as a reference, the bottom weight of the forming die base 3 is greater than the upper weight. After the forming cavity 301 is filled with material, the upper weight of the forming die base 3 is greater than the lower weight. The starting position of the forming die base 3 is located on the upper side of the material guide plate 10. At this time, the forming cavity 301 is not filled with material. The bottom weight of the forming die base 3 is greater than the upper weight. Under the action of its own weight, the upper part of the forming die base 3 swings upward, and then the electromagnet 6 is energized to adsorb and fix the forming die base 3. Subsequently, the driving mechanism 4 drives the forming die base 3 to enter the unloading cavity 301.
