s2, when the raw materials pass through the compression channel (8), the raw materials are converted into liquid raw materials, when the raw materials are stored in the compression bin (10) enough for one-step forming, the speed reducing motor (6) and the valve (9) are closed, the second cylinder (24) is started, and the output end of the second cylinder (24) drives the middle push plate (21) to move, so that the male die (19) gradually approaches the female die (18);

s3, after the male mold (19) and the female mold (18) are closed, the piston (12) is driven to move downwards through the output end of the first air cylinder (11), the piston (12) drives the raw materials in the compression bin (10) to enter the liquid outlet pipe (14), and then the raw materials enter a space between the female mold (18) and the male mold (19) through the liquid inlet hole (20), and the sealing ring is obtained after forming is completed;

s4, the male mold (19) is separated from the female mold (18) after cooling, the sealing ring is adhered to one side of the female mold (18) close to the male mold (19), the stepping motor (30) is started at the moment, the output end of the stepping motor (30) drives the eccentric plate (31) to rotate, the eccentric plate (31) drives the eccentric column (32) to eccentrically move, the elliptical plate (28) is driven to vertically reciprocate, the two scraping plates (27) can be driven to simultaneously move upwards when the elliptical plate (28) moves upwards, the two scraping plates (27) are in contact with the female mold (18) and one side of the male mold (19) close to the male mold, the sealing ring with adhesion can be scraped, the sealing ring finally drops into the material collecting hopper (26), and automatic material taking is realized.
