Abstract

LA PRESENTE INVENCION SE REFIERE A UN SISTEMA DE SUJECION BIMETALICO PARA SUJETAR FIRMEMENTE UN CALENTADOR SOBRE LA SUPERFICIE EXTERIOR DE UN CUERPO DE BOQUILLA DE UN ORIFICIO DE COLADA CALIENTE. EL DISPOSITIVO DE SUJECION DEL CALENTADOR DE BANDA DE LA PRESENTE INVENCION SE COMPONE DE UNA VAINA CILINDRICA (42, 44) QUE ALOJA LA SERPENTIN DEL CALENTADOR (36). LA VAINA TIENE UN MANGUITO INTERIOR (42) FORMADO DE UN MATERIAL QUE TIENE UNA DILATACION TERMICA RELATIVAMENTE ALTA Y UN MANGUITO EXTERIOR (44) FORMADO DE UN MATERIAL CON UNA DILATACION TERMICA RELATIVAMENTE BAJA. EL SERPENTIN DEL CALENTADOR (36) SE ENCUENTRA COLOCADO ENTRE LOS DOS MANGUITOS. EL EFECTO DE SUJECION DESEADO SE PRODUCE A BASE DE FORMA AL MENOS UNA RANURA AXIAL (54) EN EL MANGUITO INTERIOR. SE HA DESCUBIERTO QUE, DURANTE EL CALENTAMIENTO, EL MANGUITO EXTERIOR (44) SE DILATA MENOS QUE EL MANGUITO INTERIOR (42) DEBIDO A LAS DIFERENCIAS EN LOS COEFICIENTES DE DILATACION TERMICA DE LOS MATERIALES UTILIZADOS PARA FORMAR LOS MANGUITOS. ESTO PRODUCE UNAS FUERZAS RADIALES EN EL MANGUITO INTERIOR QUE LA RANURA AXIAL REDIRIGE A FUERZAS CIRCUNFERENCIALES. ESTAS FUERZAS CIRCUNFERENCIALES HACEN A SU VEZ QUE LA RANURA SE CIERRE CON LO QUE SE ALCANZA EL EFECTO DE SUJECION DESEADO. EL DISPOSITIVO DE SUJECION DEL CALENTADOR DE BANDA DE LA PRESENTE INVENCION ES UTIL PARA UTILIZARLO EN MAQUINAS DE MOLDEO POR INYECCION CON SISTEMAS DE ORIFICIOS DE COLADA CALIENTE PARA PROPORCIONAR UN MATERIAL DE PLASTICO FUNDIDO DESDE UNA FUENTE HASTA UNA COMPUERTA DE INYECCION.
