Abstract
An apparatus for providing a vacuum in a segmented tire mold includes an upper sidewall assembly and lower sidewall assembly, a plurality of radially moveable tread mold segments operable with the upper sidewall assembly and lower sidewall assembly to define a tire mold cavity. A conical actuating ring assembly surrounds the tire mold segments and engages the mold segments to provide radial movement of the mold segments. The apparatus includes a first seal between the conical actuating ring assembly and the lower mold assembly, as well as a second seal between the conical actuating ring and the upper sidewall assembly, thereby sealing the space defined by the tire mold so that a vacuum can be drawn on the tire mold cavity upon the closing of the mold.
