Abstract

MEJORAS EN DISPARADORAS DE MACHOS PARA PROCESO AUTOFRAGUANTE CON SISTEMA DE VACIO. CONSISTEN EN DISPONER ALREDEDOR DE LA CAJA DE MACHOS (2), ESTABLECIENDO UNA CAMARA PRACTICABLE (14) ENTRE EL CARTUCHO DE SOPLADO (4) Y LA MESA (1), CON CIERRE ESTANCO SOBRE ESTOS ELEMENTOS, UNA CAMPANA (9) PROVISTA DE UNA CONEXION (13) A UNA BOMBA DE VACIO, DE MANERA QUE PREVIAMENTE A LA APERTURA DE LA VALVULA (6) QUE ORIGINA LA DESCARGA DEL CARTUCHO DE SOPLADO (4) EN EL INTERIOR (15) DE LA CAJA DE MACHOS (2), AL SENO DE ESTA ULTIMA, A TRAVES DE SUS CLASICOS ORIFICIOS (8) DE EVACUACION DE AIRE Y TAMBIEN A TRAVES DE LA CAMARA ENVOLVENTE (14), SE SUMINISTRA UNA DEPRESION O VACIO QUE FAVORECE DE FORMA MUY CONSIDERABLE LA DESCARGA DEL CARTUCHO SE SOPLADO (4), PERMITIENDO QUE ESTA SE EFECTUE, INCLUSO EN MACHOS MUY COMPLEJOS O VOLUMINOSOS, SIN NECESIDAD DE UTILIZAR BOQUILLAS O CABEZALES DE SOPLADO ESPECIALES, ES DECIR, PERMITIENDO UTILIZAR UNA BOQUILLA DE SOPLADO (5) UNIVERSAL, PARA TODOS LOS CASOS, SIN RIESGO DE QUE LA MEZCLA ARENA/AGLOMERANTE PUEDA NO LLEGAR A LUGARES RECONDITOS DE LA CAJA DE MACHOS (2).
