Abstract
A tire mold is described that includes a plurality of tread molding segments having an inner surface for molding the tire tread. The mold further includes a plurality of sidewall plates having an inner surface for molding the tire sidewall. The tread mold segments together with the sidewalls cooperate to form a tire molding cavity. The sidewall plate further comprises a slot that extends from the outer surface of the tread segment to the inner mold surface, and has a pin extending from the outer surface of the tread segment. The pin is mounted to a rotatable body which can swivel. The rotatable body further comprises a guide pin which cooperates with a working member to rotate the body into a desired position in order to position the pin in the tire tread to be molded. The working member actuates the rotatable body into various positions.
