[0013] S1: The upper mold plate of the external compression equipment is driven to rise to a set height, the floating lower mold and the side cutting seat are raised to a high point under the elastic action of the second-order spring and the first-order spring, and the material to be formed is placed on the lower mold table of the floating lower mold;

[0014] S2: The upper mold plate of the external compression equipment is driven to press down, the air valve guide rod slides downward with the upper mold plate, the bottom circular table of the air valve guide rod is located below the opening of the air passage groove in the side wall of the air pressure cavity, a negative pressure is formed in the air pressure cavity of the base, the negative pressure is transmitted to the square slot through the air passage, the square table seat of the floating lower mold slides up and down in the square slot of the base, and the negative pressure is transmitted to the air holes on the upper surface of the lower mold table through the air passage, so that the material is tightly adsorbed on the lower mold table;

[0019] The beneficial effects of the present application are:

[0020] 1. The air valve guide rod is pressed down with the upper template. The bottom truncated cone of the air valve guide rod slides downward below the opening of the air passage groove on the side wall of the air pressure chamber. A negative pressure is formed in the air pressure chamber of the base. The negative pressure is transmitted to the square slot through the air passage. The square platform of the floating lower mold slides up and down in the square slot of the base. The negative pressure is transmitted to the air hole on the upper surface of the lower mold through the air passage, which tightly adsorbs the material on the lower mold. No other external vacuum device is required, which reduces the production cost. At the same time, it effectively avoids the situation where the material detaches due to vibration during equipment pressing and improper molding occurs.

[0021] 2. During the process of the floating lower mold pressing down until its lower mold base is in contact with the upper surface of the side cutting seat, the conical rod of the floating lower mold slides down, and the conical surface of the conical rod abuts against the oblique conical opening of the Z-type cutter. The conical rod pushes the cutting head of the Z-type cutter to protrude to the left of the side cutting seat until the cutting head of the Z-type cutter cuts through the material from the side. The external pressing equipment drives the upper mold plate to continue pressing down until the bottom surface of the side cutting seat abuts against the limiting platform. The first spring is compressed, the second spring is compressed, and the side cutting seat rotates counterclockwise and slides downward under the guidance of the spiral groove in the central shaft hole of the base. The side cutting seat drives the cutting head of the Z-type cutter to fit against the bottom surface of the lower mold base and rotate counterclockwise for one revolution to cut the soft label material from the side wall to form a complete bottom sealing edge, thus completing the forming of the gilded soft label material. The forming and pressing of the soft label and the cutting of the bottom sealing edge are integrated into one. Compared with the transmission method of pressing and forming first and then cutting and sealing the edge, the current method has faster production efficiency and higher material capacity.

[0022] 3. The external pressing equipment drives the upper template to rise, and the air valve guide rod rises with the upper template. Positive pressure is formed in the air pressure chamber of the base. At the same time, the upper mold groove of the upper template separates from the lower mold platform of the floating lower mold. The material pressed on the lower mold platform of the floating lower mold is blown off the lower mold platform by the positive pressure airflow in the air hole on the upper surface of the lower mold platform, realizing automated material unloading. There is no need for manual labor to put hands into the pressing area to pick up materials, which improves production efficiency and avoids the risk of personnel being crushed.

The square platform of the floating lower mold slides up and down in the square slot of the base. The negative pressure is transmitted to the air hole on the upper surface of the lower mold through the air passage, so that the material is tightly adsorbed on the lower mold platform. S3: When the lower mold table is pressed down to the point where the bottom surface of the lower mold table of the floating lower mold is in contact with the upper surface of the side cutting seat, the first spring is compressed and the second spring is not compressed. At the same time, the upper mold groove of the upper mold plate and the lower mold table of the floating lower mold cooperate to press the material into shape in the cavity formed therein. S4: During the process of the floating lower die being pressed down until the bottom surface of its lower die table is in contact with the upper surface of the side cutting seat, the conical rod of the floating lower die slides down, the conical surface of the conical rod abuts against the oblique conical opening of the Z-type cutter, and the conical rod pushes the cutting head of the Z-type cutter to protrude to the left of the side cutting seat until the cutting head of the Z-type cutter cuts through the material from the side. S5: The external pressing equipment drives the upper template to press down continuously until the bottom surface of the side cutting seat abuts against the limiting platform. The first spring is compressed, the second spring is compressed, and the side cutting seat rotates counterclockwise and slides downward under the guidance of the spiral groove in the central shaft hole of the base. The side cutting seat drives the Z-shaped cutter head to fit against the bottom surface of the lower mold table and rotate counterclockwise for one revolution to cut the soft label material from the side wall to form a complete bottom sealing edge, thus completing the forming of the gilded soft label material. S6: The external pressing equipment drives the upper template to rise, and the air valve guide rod rises with the upper template. Positive pressure is formed in the air pressure chamber of the base. At the same time, the upper mold groove of the upper template separates from the lower mold platform of the floating lower mold, and the material pressed on the lower mold platform of the floating lower mold is blown away from the lower mold platform by the positive pressure airflow in the air hole on the upper surface of the lower mold platform, thus realizing material removal.
