Abstract

PROCEDIMIENTO Y DISPOSITIVO DE SOPLADO DE MACHOS COMPLEJOS CON PRESION DE SOPLADO REDUCIDA. CONSISTE EN ESTABLECER, ENTRE EL CARTUCHO DE ARENA (3) Y LA CAJA DE MACHOS (8), UNA PLURALIDAD DE BOQUILLAS DE SOPLADO (15), EN NUMERO Y DISPOSICION VARIABLE EN FUNCION DE LAS CARACTERISTICAS DE DISEÑO DE CADA MACHO (9) A OBTENER, PARA CONSEGUIR UN MAS FACIL ACCESO DE LA ARENA A LAS DIFERENTES ZONAS DE LA CAJA DE MACHOS Y UNA MEJOR COMPACTACION DE LA MISMA, CON MENOR PRESION DE TRABAJO. ADEMAS SE HA PREVISTO TAMBIEN QUE EL ALOJAMIENTO (9) PARA EL MACHO, ENTRE LAS DOS SEMI-CAJAS DE MACHOS (8-8''), COMUNIQUE CON EL COLECTOR GENERAL INFERIOR (10) PARA RECOGIDA DEL AIRE DE DISPARO RESIDUAL, NO SOLO A TRAVES DE LOS ORIFICIOS O CONDUCTOS (20) ESTABLECIDOS EN LA SEMI-CAJA INFERIOR (8), SINO TAMBIEN A TRAVES DE CONDUCTOS (21), CONTRAPUESTOS A LOS ANTERIORES, QUE SE DESEMBOCAN EN UN COLECTOR AUXILIAR, SIMPLE (22) O MULTIPLE (22''), DIRECTAMENTE COMUNICADO CON EL COLECTOR GENERAL (10) A TRAVES DE ORIFICIOS O CONDUCTOS (23) QUE ATRAVIESAN LA PROPIA CAJA DE MACHOS (8-8'').PROCEDURE AND DEVICE FOR BLOWING MALE COMPLEXES WITH REDUCED BLOWING PRESSURE. IT CONSISTS IN ESTABLISHING, BETWEEN THE SAND CARTRIDGE (3) AND THE BOX OF MALES (8), A PLURALITY OF BLOWING NOZZLES (15), IN NUMBER AND VARIABLE ARRANGEMENTS ACCORDING TO THE DESIGN CHARACTERISTICS OF EACH MALE (9) OBTAIN, TO ACHIEVE A MORE EASY ACCESS OF SAND TO THE DIFFERENT AREAS OF THE CAJA DE MACHOS AND A BETTER COMPACTION OF THE SAME, WITH LESS WORKING PRESSURE. IN ADDITION, IT IS ALSO PROVIDED THAT THE ACCOMMODATION (9) FOR THE MALE, BETWEEN THE TWO SEMI-BOXES OF MALES (8-8 ''), COMMUNICATE WITH THE LOWER GENERAL COLLECTOR (10) TO COLLECT THE RESIDUAL TRIP AIR, NOT ONLY THROUGH THE HOLES OR DUCTS (20) ESTABLISHED IN THE BOTTOM SEMI-BOX (8), BUT ALSO THROUGH DUCTS (21), OPPOSITE TO THE PREVIOUS, WHICH LAND IN A AUXILIARY MANIFOLD, SINGLE (22) OR MULTIPLE (22``), DIRECTLY COMMUNICATED WITH THE GENERAL COLLECTOR (10) THROUGH HOLES OR DUCTS (23) THROUGH THE OWN BOX OF MALE (8-8 '').
