Abstract

PURPOSE: To prevent exhaust gas from leaking from exhausting parts and to obtain a nice-looking rubber molded article by a method wherein a concave part for inserting a molded article is provided on the internal surface of the pressurized side of an external cylinder body with a valve seat and a valve part is equipped at the bottom of the concave part.
CONSTITUTION: If an unvulcanized tire is stored in a die F and heated by the steam in pressing contact with the die F through an expanded bladder, gas like the air and so forth between the surface of the unvulcanized tire and the internal surface of the die F is exhausted from between the valve seat 2 and the valve part 4 of a vent unit E through a space 1a and a narrow gap 1b. As the time elapses, the unvulcanized rubber T is pushed into the cavity 5 of the vent unit E for introducing the molded matter. Further, if the rubber is pressed to the vent unit E by back-pressure, the rubber comes into the blind hole 6 of a movable body 3. While the rubber is coming in, the increase of pressure to the rubber lags, vulcanization advances the fluidity goes down and it becomes impressible for the rubber to pass through the seal part.
