Abstract

MEJORAS EN MAQUINAS DE MOLDEO DE CAJAS DE ARENA POR IMPACTO DE AIRE. TALES MEJORAS CONSISTEN EN DISPONER, EN LA EMBOCADURA DE UNA TOLVA (8) SUMINISTRADORA DE ARENA Y POR DEBAJO DE LA COMPUERTA (6) DE SUMINISTRO DOSIFICADO DE DICHA ARENA, UN MOTOR (9), MONTADO SOBRE UN SOPORTE (10) Y CON UNA CHAPA DE PROTECCION (15) FRENTE A LAS DESCARGAS DE ARENA, QUE ACCIONA UNA SERIE DE ASPAS INFERIORES (12) QUE REPARTEN Y NIVELAN LA ARENA EN EL SENO DE LA CAMARA DE COMPACTACION (4). LA VALVULA DE DESCARGA SE SITUA ANULARMENTE POR FUERA DE LA TOLVA Y EN ELLA PARTICIPA EL OBTURADOR ANULAR (26), CON UN FRENTE DIEDRICO DE CIERRE PARA EL ORIFICIO TAMBIEN ANULAR (18) Y QUE JUEGA EN UN ALOJAMIENTO (25) DE UN ANILLO SOPORTE (22).
