Tire mold vent plug and method |
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.
