Tire vulcanization mold |
摘要 |
A tire vulcanization mold comprises a mold body having an inner surface for molding a tire outer surface and at least one vent passage for the escape of gas in the mold during vulcanization, the vent passage with an inlet end and an outlet end, the inlet end being opened on the inner surface of the mold body, the outlet end communicating with an exterior of the mold body, wherein the vent passage communicates with the inner surface of the mold body at an angle of not less than 60 degrees, and less than 90 degrees with respect to a normal line perpendicular to the inner surface at the inlet end. |
