Abstract:
A curing mold includes an upper mold portion having a plurality of upper and lower sections radially translatable between open and closed positions, wherein each of the lower sections are positioned adjacent one of the upper sections to form a plurality of pairs of upper and lower sections. The tire mold also includes a pin extending from a first section of each pair of sections, and an aperture extending within a second section of each pair of sections, the aperture including an opening and positioned for receiving a portion of the pin extending from the corresponding first section when the mold is in a substantially closed position. Particular embodiments of the present invention also include a first plurality of radially translatable sections arranged to form an expandable ring and one or more first synchronization members extending between adjacent sections of the first plurality of sections.
