PURPOSE:To prevent mutually mixing of the textiled for molding a seal member through dividing a cavity into inner and outer peripheries by fitting a textile separating ring projecting elastically downward against a top force and by pushing the lower end of the above ring, at mold closing, to a reinforcement ring. CONSTITUTION:When mold closing is started, the lower end of a product pushing off pin 9 is caused to contact with a reinforcement ring (a), and said pin 9 is relatively slid upward. At the stage where the lower end of the pin 9 and the lower end of the leg part of a ring 8 are well-regulated, the leg lower end of the ring 8 is caused to contact with the reinforcement ring (a), and the pin 9 and the ring 8 are slidably moved together relatively to the inner and outer top forces 2, 3. Due to the movement of the ring 8, the leg lower end of the ring 8 and the reinforcement ring (a) are forcibly compressed by the spring force of a spring 12, and a cavity 6 is divided into an inner peripheral part and an outer peripheral part, being bounded by said compressed part. When mold closing is completed and the textiles d', e' for molding seal members are stuck to the reinforcement ring (a) and further their crosslinking and curing are finished, the mold is opened, and the product pushing off pin 9 is projected downward, whereby the product is released from the mold.
