Abstract
Sectional molds for tires wherein radially movable sectors are mounted in a permanent way on a fixed lower casing of the mold in such a way that the sections do not have to be lifted and pulled up with a movable upper platform, when the press of the mold is opening. The sectors are connected to the lower casing which supports them by connecting means such as linked struts that are operatively associated with the sectors, at the beginning of the opening of the mold, having at the same time a slight lifting movement parallel to the lower casing and a slight radial backward movement assuring the detachment of the sectors with respect to the tread of the molded tire.
