working principle:

When installing the lower mold body 11, first place the lower mold body 11 at the middle end of the top of the bottom box 2, and then control the second electric telescopic rod 901 through the external controller, and the output end of the second electric telescopic rod 901 is directed to One side shrinks, driving the first tooth plate 903 to move horizontally to one side, and driving the first fixing rod 907 to move horizontally. The second toothed plate 906 is driven to move horizontally in the opposite direction of the first toothed plate 903 through the meshing action of the teeth, and the second toothed plate 906 drives the second fixed rod 908 to move horizontally. The first fixed rod 907 and the second The fixing rod 908 drives the clamping blocks 909 on both sides to move inward at the same time, so that the clamping blocks 909 are clamped in the inner cavity of the clamping slot 15, which facilitates the fixing of the mounting plate 12 and the lower mold body 11;

When disassembling the lower mold body 11 , the second electric telescopic rod 901 is first controlled by the external controller, the output end of the second electric telescopic rod 901 extends to one side, and drives the first tooth plate 903 to move horizontally to one side , and drives the first fixed rod 907 to move horizontally, while the first toothed plate 903 drives the gear 905 to rotate clockwise through the meshing action of the teeth, and the gear 905 drives the second toothed plate 906 to the first toothed plate 906 through the meshing action of the teeth. The toothed plate 903 moves horizontally in the opposite direction of the movement, the second toothed plate 906 drives the second fixed rod 908 to move horizontally, the first fixed rod 907 and the second fixed rod 908 simultaneously drive the clamping blocks 909 on both sides to move to the outside, so that the clamping The block 909 is no longer clamped in the inner cavity of the card slot 15, which facilitates the disassembly of the mounting plate 12 and the lower mold body 11;

When discharging, the first electric telescopic rod 401 is controlled by the external controller, the output end of the first electric telescopic rod 401 shrinks downwards, and drives the lower mold body 11 to move downwards.
