A Bladder Control Apparatus In Tire Curing Press Center Mechanism And A Method Thereof
Abstract: The present invention provides a central mechanism for shaping and/or curing of a tire in a tire curing press. The central mechanism comprising a bladder control apparatus, to control an expansion and/or retraction of the bladder. The apparatus according to present invention provides movement to lower clamp ring and top clamp ring. Bladder is clamped between top clamp ring and lower clamp ring. The top clamp ring is connected to piston rod of top ring cylinder. The movement of top clamp ring manipulates the height of bladder relative to tire height. The movement of lower clamp ring ejects the tire out of lower mold along with top ring cylinder and bladder. The present invention relates to actuation of top clamp ring and lower clamp ring though hydraulic actuators. The present invention has simplified arrangement of hydraulic actuators.
