VULCANIZATION MOLDING DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent a rubber molding from being qualitatively deteriorated by the entrainment of steam and air, in a vulcanization molding device for a rubber sheet and the like. SOLUTION: The open vulcanization molding device is structured of a combination of a cylindrical mold 2 around which a molding material such as the rubber sheet is wound and pressurizing rolls 10 arranged around the former. Air enveloped in a rubber material is allowed to escape by the pressurizing rolls 10 and the rubber material and the steam are prevented from coming into contact with each other by using a steam electromagnetic induction coil and a realed heat medium as heating means.
