Abstract

UN METODO Y APARATO PARA MOLDEAR ARTICULOS DE PLASTICO POR SOPLADO QUE UTILIZA UNA O MAS AGUJAS FIJAS Y UNO O MAS MICROORIFICIOS DE VENTILACION ASOCIADOS A UNA CAVIDAD DE MOLDEO POR SOPLADO. CADA AGUJA TIENE UN PRIMER CONDUCTO ASOCIADO A ELLA A TRAVES DEL CUAL SE SUMINISTRA VACIO PARA ATRAER EL PLASTICO DERRETIDO EN TORNO A LA AGUJA Y UN SEGUNDO CONDUCTO EN SU INTERIOR A TRAVES DEL CUAL SE INTRODUCE AIRE A PRESION PARA SEPARAR EL PLASTICO E INFLAR EL ARTICULO CONTRA LOS LIMITES DEL MOLDE QUE SE HA CERRADO SOBRE EL PARISON PLASTICO. LOS MICROORIFICIOS DE VENTILACION FACILITAN LA EXTRACCION DEL AIRE QUE RODEA EL PARISON. PREFERIBLEMENTE EL SEGUNDO CONDUCTO PARA EL AIRE COMPRIMIDO ESTA PROVISTO DE UN CALIBRE CENTRAL Y EL PRIMER CONDUCTO PARA EL VACIO ESTA PROVISTO DE UN ESPACIO ANULAR EN TORNO A LA AGUJA FIJA. EN UNA FORMA MODIFICADA, LA AGUJA FIJA COMPRENDE CONDUCTOS DE AIRE DOBLES. ESTA PREVISTA LA UTILIZACION DE VARIOS MOLDES CON CONTROLES PARA SUMINISTRAR AIRE Y VACIO.
