摘要： This invention relates to a mold for molding prefoamed material of thermoplastic synthetic resin, in which the foamed product is provided with a smoothened superficial skin layer on the overall surface thereof, a beautiful external appearance and a remarkable strength. The mold according to this invention consists of a pair of molds each of which is provided with an internal wall facing to a cavity and an external wall not facing to the cavity, and either one of or each of which is provided with at least one heating chamber including a steam inlet and a steam outlet both of which are mounted in the external wall. And either one of or each of the two molds is provided with a plurality of steam passages and a surface-heating chamber independent thereof both of which are mounted in the internal wall.
