[0025] During specific use, the rotation of the motor 4 drives the connected cam 5 to rotate together, and at the same time, the abutting connecting rod assembly 6 is extended and retracted up and down in the base 3 and the mold body 1 that are connected through the cam 5, thereby driving the connecting frame 7 and the demolding ring 8 connected at the top to lift and eject the molded sealing ring embedded in the mold body 1.

[0026] Preferably: the surface of the support frame 2 abuts against the suction hood 9, the surface of the suction hood 9 is longitudinally penetrated by the connecting bolt 10, the bottom surface of the bolt 10 is threadedly connected to the storage box 11, the bottom surface of the storage box 11 abuts against the mounting plate 12, the surface of the mounting plate 12 is connected to the side surface of the base 3, the bottom surface of the storage box 11 is installed with a connecting pipe 13, the surface of the connecting pipe 13 longitudinally penetrates the connecting mounting plate 12, the inner wall surface of the connecting pipe 13 is threadedly connected to the telescopic pipe 14, the surface of the telescopic pipe 14 is connected to the suction fan 15, and the bottom surface of the suction fan 15 abuts against the base 3.
