Abstract
An apparatus for vulcanizing an elastomeric product includes a mold in which the elastomeric product to be vulcanized is disposed, a piston gland having a first supply passage for supplying a heating medium, and an annular junction chamber. The first supply passage communicates with the interior of the junction chamber. The junction chamber has an outer wall which separates the junction chamber from the interior of the product, and a nozzle in the outer wall directs heating medium from the junction chamber into the interior of the product in a downward direction toward the lower portion of the product. An enclosure overlies the junction chamber. The piston gland has a second supply passage for supplying a pressurizing medium which communicates with the enclosure to supply pressurizing medium to the enclosure, the pressurizing medium passing from the enclosure to the interior of the product.
