  • Patent number: 8361359
    Abstract: In a tire vulcanizer configured to perform opening and closing of a mold using an efficient ball screw shaft or the like, a top mold mounting member holding a top mold is lifted and lowered by rotating the ball screw shaft with a driving mechanism to vertically lift and lower a ball nut, and the lifting and lowering of the top mold mounting member is stopped by fixing the ball screw shaft by the de-excitation of an electromagnetic brake connected directly to the ball screw shaft, independently from the driving mechanism. According to such a structure, the opening and closing of the mold can be stopped, even if abnormality of the driving mechanism or the brake occurs.
