Metal mold for vulcanization of tires

摘要

An upper half of a mold for vulcanization of tires mounted on a vulcanization press machine is composed of an inner mold portion and an outer mold portion. The contacting face of the outer mold portion to the inner mold portion is tapered to allow a downward movement of the inner mold portion independent of the outer mold portion. With the downward movement of the inner mold portion, the tire is easily separated from the outer mold portion due to deformation.
