Abstract

SE PRESENTA UN PROCESO PARA FUNDICION DE INYECCION DE SUELAS DE GOMA AL MENOS DE DOS CAPAS O CORRESPONDIENTEMENTE DE MEZCLAS DE GOMAS Y COMPUESTOS DE LAS MISMAS ASI COMO EVENTUALMENTE UNIDAS CON LA CAÑA DEL ZAPATO. EN PRIMER LUGAR LA MEZCLA DE GOMA SE INYECTA EN EL ESPACIO HUECO DEL MOLDE AGRANDADO PREVISTO PARA LA CAPA DE LA SUELA Y A CONTINUACION ESTA CAPA SE DISMINUYE DE ACUERDO CON EL VOLUMEN DE LA CAPA DE SUELA CORRESPONDIENTE. DESPUES DE UNA FIJACION PREVIA PARCIAL DE LA MEZCLA DE GOMA SE SUSTITUYE LA LIMITACION SUPERIOR PARA LA CAPA DE SUELA A TRAVES DE UNA HORMA. EN EL ESPACIO HUECO DEL MOLDE GENERADO SE INYECTA LA MEZCLA DE GOMA PARA LA CAPA DE LA SUELA INTERMEDIA. MEDIANTE EL DESPLAZAMIENTO DE LA CAPA DE PLANTILLA HACIA ARRIBA SE DISMINUYE EL ESPACIO HUECO DEL MOLDE DE ACUERDO CON EL TAMAÑO DE LA CAPA DE PLANTILLA INTERMEDIA. DESPUES DE LA FIJACION PREVIA PARCIAL DE LA MEZCLA DE GOMA SE DESCIENDE LA DELIMITACION INFERIOR DE LA CAPA INTERMEDIA SEGUN UNA ZONA O TRAMO DETERMINADO Y SE CONTROLA LA PLANTILLA INTERMEDIA MEDIANTE EL ESPACIO HUECO DEL MOLDE AGRANDADO EN UN PROCESO DE EXPANSION. EL DISPOSITIVO (FIG.6) SEGUN LA INVENCION TIENE PREVISTO UNA PIEZA (1) INTERMEDIA, QUE ESTA APLICADA ENTRE LAS PIEZAS (16A) LATERALES DEL MOLDE Y UNA ESTAMPACION (2) DEL FONDO, SIENDO MOVIL TANTO EN DIRECCION HORIZONTAL COMO VERTICAL.
