ABSTRACT:
A dual cavity tire press having side by side mold sections incorporate vertically extending center mechanisms which include a shaping bladder. The center mechanisms are moved vertically after the press opens while the bladder is within the tire to strip the tire from the bottom mold sections. Vertical movement of the center mechanisms is obtained by a single floating horizontally disposed piston-cylinder assembly which is mounted at the front of the press outside of the base, each end of the piston-cylinder assembly being connected through a lever arrangement to move the respective bead lift posts of the center mechanisms vertically. When the piston-cylinder assembly is pressurized, its entire force is applied simultaneously to each center mechanism to move the same vertically and such force is maintained throughout the vertical height movement of both center mechanisms. By a removable stop or lock, one of the center mechanisms may be made inoperable without affecting the movement and operation of the other.
