[0052] The lower die 1 is provided with a discharging assembly matched with the toothed plate 5, and the discharging assembly and the driving assembly are connected through a transmission structure. During the action of the discharging assembly, when the discharging assembly contacts with the toothed plate 5, the iron core raw material supporting plate 4 will move horizontally, and when the discharging assembly is separated from the toothed plate 5, the iron core raw material supporting plate 4 will remain stationary.
[0053] In the present scheme, the plate material is first installed on the iron core raw material supporting plate 4, and the upper die 3 vertically reciprocates under the action of the driving assembly, so as to cooperate with the lower die 1 to stamp the plate material on the iron core raw material supporting plate 4;
[0054] Since the iron core raw material supporting plate 4 is connected with the lower die 1 through the elastic supporting structure, the material plate is suspended above the lower die 1, therefore, when the upper die 3 approaches the lower die 1, the upper die 3 will push the material plate downward to make the material plate fit the lower die 1, at this time, the elastic supporting structure will be compressed, when the upper die 3 moves away from the lower die 1, the elastic supporting structure will drive the material plate to reset through the iron core raw material supporting plate 4;
