ABSTRACT:
A tire curing press for the curing of radial tires includes top and bottom mold sections, relatively movable top and bottom bead rings, the latter being on top of a well, and a center mechanism in the bottom bead ring well. The top mold section includes a sectional mold operator, a top bead ring actuator and an actuator for raising and lowering a chuck for the top bead ring of an uncured tire. The chuck includes a series of horizontal L-shape plates each of which swings about a respective swing axis. An open vertical tube aligned with the top mold section includes a gear at its bottom in mesh with gear segments on the chuck plates so that rotation of the tube opens and closes the chuck. The extent of rotation of the tube controls the extent of the chuck. Such tube is open at the bottom and also serves as an inflation pipe for introducing air pressure into the interior of the uncured tire when the beads thereof are adjacent the mold bead rings for centering the uncured tire and snapping the beads of the tire on the mold bead rings in proper sealed engagement for subsequent closing of the press and shaping of the tire. The actuators for the sectional mold mechanism, the top bead ring, and the raising and lowering of the chuck are arranged in a cascading fashion.
