摘要： In a tire mold having a pair of mold parts separable about cooperating surfaces of the respective mold parts which define a parting line region, each of the mold parts includes a surface defining at least a portion of a cavity for shaping a tire. The tire mold further includes a plurality of pockets for defining a respective plurality of circumferentially arranged tread elements in the tire. The improvement comprises a vacuum source in fluid communication with the cavity of the tire mold for evacuating fluid from the cavity in the tire mold through a space located between the surfaces of the mold parts which define the parting line region. A vent fluidly connects a pair of adjacent pockets. A passage associated with one of the mold parts provides fluid communication between the vacuum source and one of the pair of adjacent pockets connected by the vent.

摘要： A mold for curing a green tire which is made of an elastomeric material capable of flowing prior to curing. The mold includes a surface defining a cavity in the mold for receiving the green tire. A passage communicates the cavity with the exterior of the mold. A vent plug is located in the passage. The vent plug has an opening extending therethrough communicating the cavity with the passage. Elastomeric material may flow into the opening to form a projection extending from the tire as the green tire is pressed against the surface defining the cavity during a molding operation. The vent plug has a portion extending into the cavity a predetermined distance from the surface to form a recess in the tire adjacent the projection. The recess provides a space that the projection may deflect into to prevent shearing off of the projection during removal of the tire from the mold.
