A vulcanization molding device for producing a rubber sealing ring as claimed in claim 8, characterized in that: A worm (612) for transmission is also provided on the top of the mounting seat (601); one end of the worm (612) is rotatably connected to a linkage gear (613); the linkage gear (613) is transmission-connected to a linkage rack (614); the bottom of the linkage rack (614) is fixedly connected to the linkage rod (38).

10. A vulcanization molding method for producing a rubber sealing ring based on the device according to any one of claims 1 to 9, characterized in that: The steps include: S1, adding raw materials for rubber ring production into the feeding chamber (11), and conveying the raw materials to the barrel (24) through the feeding chamber (11) to heat the raw materials; S2, controlling the first transmission member (14) to drive the guide platform (15) to move upward, so that the guide platform (15) drives the movable mold base (31) to move upward and form a mold-closing state with the fixed mold base (41), and at the same time the movable mold base (31) drives the concentricity adjustment component (6) to adjust the concentricity of the injection component (2); S3, controlling the electric push rod (21) to drive the nozzle adjustment assembly (5) and the second transmission member (22) to cause the nozzle (25) to move downward until the limit table (26) contacts the top of the limit seat (12), at which time the nozzle (25) is just inserted into the center hole at the top of the fixed mold seat (41) to form a seal; S4. Control the second transmission member (22) to drive the screw in the barrel (24) to rotate. During the rotation of the screw, the molten rubber raw material in the barrel (24) can be injected into the molding slider (33) to realize vulcanization molding of the rubber ring.
