Abstract

UN APARATO PARA MOLDEAR POR SOPLADO UN ARTICULO CURVO EN TRES DIMENSIONES, QUE CONSTA DE DOS PARTES DE MOLDE DESPLAZABLES HORIZONTALMENTE (10,12) QUE, CUANDO SE ENCUENTRAN EN CONTACTO ENTRE SI, DEFINEN UNA CAVIDAD DE MOLDE (34) CURVADA EN TRES DIMENSIONES PARA COINCIDIR CON EL ARTICULO REQUERIDO. UNA CABEZA DE EXTRUSION (68) EXTRUYE UN PARISON (80) DE MATERIAL DE RESINA SINTETICA EN LA CAVIDAD DE MANERA QUE DESCIENDA A TRAVES DEL EXTREMO INFERIOR DE LA MISMA. DURANTE ESTE PROCESO, UN RPIMER FLUJO DE AIRE SE ALIMENTA A TRAVES DE LAS ABERTURAS (84,86) EN UNA CUBIERTA (70) Y PASA A TRAVES DE LA CAVIDAD DE MOLDE ALREDEDOR DEL LADO EXTERIOR DEL PARISON PARA FACILITAR EL PASO DEL MISMO HACIA EL EXTREMO INFERIOR. ADEMAS, UN SEGUDO FLUJO DE AIRE SE ALIMENTA A TRAVÑES DEL INYECTOR (88) EN LA CABEZA DE EXTRUSION (68) HASTA EL INTERIOR DEL PARISON (80) PARA AYUDARLO A DESCENDER Y TAMBIEN PARA EVITAR SU DISTORSION MIENTRAS SE MUEVE HACIA LA CAVIDAD DE MOLDE (34). DESPUES, LOS ELEMENTOS DE CIERRE (50,52,58,60) QUE SE DESLIZAN SOBRE, PERO QUE SE MUEVEN INDEPENDIENTEMENTE, LAS PARTES DE MILDE PRINCIPAL (10,12) BLOQUEAN LOS EXTREMOS SUPERIOR E INFERIOR DE LA CAVIDAD DE MOLDE Y PINZAN EL PARISOL (80) ENTRE SI, SIENDO CONTROLADOS SUS MOVIMIENOTS POR ACTIVADORES RESPECTIVOS (54,56,62,64). EL MOLDEADO POR SOPLADO SE PRODUCE ENTONCES A TRAVES DEL INUYECTOR (88) PARA PRODUCIR EL ARTICULO REUQERIDO. LAS PARTES DE MOLDE (10,12) SE SEPARAN ENTONCES. EL ARTICULO PERMANECE SUSPENDIDO MEDIANTE LOS ELEMENOTS DE CIERRE (50,52,58,60) Y PUEDE SER CAPTADO POR UN BRAZO MANIPULADOR O ROBOTICO Y LUEGO EXTRAIDO DESPUES DE LA SEPARACION DE LOS ELEMENTOS DE CIERE (50,52,58,60).
