Zusammenfassung:	An apparatus is disclosed for providing a vacuum in a segmented tire mold (10) having an upper sidewall assembly (12) and a lower sidewall assembly (14), a plurality of radially moveable tread mold segments (16) operable with the upper sidewall assembly and the lower sidewall assembly to define a tire mold cavity (18) in the closed position of the tire mold (10), a conical actuating ring assembly (20) surrounding the tread mold segments for providing a radial movement of the tread mold segments (16) into engagement with the upper sidewall assembly (12) and the lower sidewall assembly (14). The apparatus comprises a top sealing means (501) between the actuating ring assembly (20) and the upper sidewall assembly (12) and a bottom sealing means (502) between the actuating ring assembly (20) and the lower sidewall assembly (14) such that the tire mold (10) is airtight and ready for evacuation or evacuated only when fully closed.
