Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA LA ELABORACION DE PARTES (19) DE MOLDE FORRADAS, COMO REVESTIMIENTOS INTERIORES DE AUTOMOVILES O SIMILARES, SIENDO PARTES DE FORMA ESTABLE, EN LAS QUE SE HA PREVISTO UNA PARTE SOPORTE CON UN FORRADO (14) DE LA SUPERFICIE Y DONDE PRIMERO SE HA FABRICADO UNA PIEZA (18) PREMOLDEADA EN BRUTO NO SUPERFICIALMENTE IGUAL, CON EL MISMO VOLUMEN DE LA PARTE SOPORTE, PERO CON RELACION AL MOLDEADO FINAL. ESTA PIEZA (18) PREMOLDEADA EN BRUTO SE UNE A CONTINUACION BAJO APROVECHAMIENTO DE SU CALOR DE FABRICACION, QUE SE ENCUENTRA EN SU INTERIOR, POR MEDIO DE EFECTO DE PRESIONADO CON EL FORRO (14) A TRAVES DE ESTAMPADO POSTERIOR CON EL MATERIAL SINTETICO TERMOPLASTICO DE LA PARTE SOPORTE, OBTENIENDOSE POR MEDIO DE UN PROCESO PREVIO DE FLUIDIFICACION DEL MATERIAL SU FORMA FINAL. CON LA INVENCION DEBE MEJORARSE EL PROCESO DE ESTAMPACION POSTERIOR EN LA ELABORACION DE LA PARTE (19) MOLDEADA Y FORRADA DE FORMA TAN AMPLIA QUE LAS FUERZAS DE MOLDEADO REDUCIDAS MEJOREN LA ADHERENCIA UNITARIA DE SUPERFICIE DEL FORRADO (14) SOBRE LA PIEZA SOPORTE, CON LO CUAL DEBE SER ELIMINADO ESPECIALMENTE EL PELIGRO DE LA FORMACION DE BOLSAS DE AIRE. ESTO SE CONSIGUE DE TAL MODO, QUE LA PIEZA (18) PREMOLDEADA EN BRUTO CON EL MISMO VOLUMEN DE PARTE SOPORTE FABRICADA Y CON LA MISMA FORMA DE CONTORNO QUE LA PARTE (19) MOLDEADA YA FORRADA SE SOMETE A UN PROCESO DE FLUIDIFICACION DEL MATERIAL DE LA ESTRUCTURA EN FORMA DE REJILLA EN ZONAS PARCIALES, DE TAL MODO QUE LAS MASAS DE REJILLA PRIMERAMENTE ABIERTAS DE LA PIEZA PREMOLDEADA EN BRUTO SE CIERRAN CON IMPULSION DE PRESION PARA EL PROCESO DE ESTAMPACION POSTERIOR A TRAVES DE FLUIDIFICACION LOCALIZADA.
