Abstract
Un molde para preparar un artículo de estructura celular de resina termoplástica, comprendiendo dicho molde un dispositivo de abertura de vapor que incluye un elemento de abertura que se extiende a través del mismo y un elemento móvil introducido en disposición movible en dicho elemento de apertura, estando éste formado por una pared cónica truncada ensanchada progresivamente hacia el extremo en un lado y una pared cilíndrica en el otro lado, teniendo dicha pared cónica y dicha pared cilíndrica un eje común, disponiendo dicho elemento móvil de una superficie cónica truncada que corresponde a dicha pared cónica truncada y una superficie cilíndrica, formando dicho elemento móvil un hueco entre la superficie cónica truncada y la pared cónica truncada cuando se levanta el elemento móvil del elemento de abertura, en el cual se halla formado un paso de vapor en al menos uno de dicho elemento de abertura y dicho elemento móvil, estando abierto un extremo del paso de vapor en dicho otro lado y comunicando el otro extremo del paso de vapor con el hueco formado cuando se levanta el elemento móvil, un tubo para introducir el vapor, y un tubo para agua de refrigeración, : en el cual dicho dispositivo de abertura de vapor se halla colocado en posición en una plancha de la cavidad de dicho molde, comunicando dicho dispositivo de abertura de vapor con dicho tubo para introducir el vapor, y disponiéndose dicho tubo para agua de refrigeración de manera que enfrie la superficie exterior de dicha plancha de la cavidad.
