Abstract

SE TRATA DE UN DISPOSITIVO PARA PRODUCIR IMPULSOS DE AIRE COMPRIMIDO PARA COMPACTACION DE ARENA DE MOLDEO EN CAJAS DE MOLDEO. CONSISTE EN UNA CAMARA EN FORMA CIRCULAR, EN LA QUE SE INSUFLA AIRE COMPRIMIDO, EL CUAL ESTA CONCECTADO, POR UNA SERIE DE VALVULAS Y TOBERAS DE PENETRACION QUE PUEDEN GIRAR EN VARIAS DIRECCIONES, CON EL ESPACIO DE MOLDEO. EL CUAL ESPACIO ESTA LIMITADO POR LOS MARCOS DOSIFICADORES Y UN COMPRESOR PRINCIPAL, POR ENCIMA DE LA ARENA QUE SE ENCUENTRA EN EL MOLDE. EL DISPOSITIVO PUEDE SER INSTALADO TANTO EN MAQUINAS MOLDEADORAS DE FUNDICION COMO DIRECTAMENTE EN CAJONES DE MOLDEO A LA ALTURA DE LOS MARCOS DE DOSIFICACION.
