Abstract
A tire mold vent assembly includes a cylindrical vent housing having a slot defined therein along the length of the housing to provide a circumferential flexibility to the vent housing. An elastomeric insert is received in the slot and includes a head extending laterally from one end of the housing. The head is movable between a first position permitting air flow into the passage through the housing, and a second position which blocks the passage to prevent sprue formation.
