Abstract

ESTA INVENCION EXPONE UN MECANISMO DE ACTUACION HIDRAULICA PARA UN SISTEMA DE MOLDEO POR INYECCION DE UN GRIFO DE VALVULA EN DONDE EL CABEZAL ALARGADO DE LA AGUJA DE VALVULA ES CONECTADO DESMONTABLE CON EL PISTON Y UN CIERRE FLOTANTE QUE ESTA PROVISTO EN CONTRA DE LA DISPERSION DEL FLUIDO HIDRAULICO. EL MECANISMO DE ACTUACION TIENE UN PISTON, EL CUAL ES ALTERNATIVO EN UN CILINDRO ENTRE POSICIONES ABIERTAS Y CERRADAS. LA COMPUESTA SE EXTIENDE A TRAVES DE UN HUECO EN EL PISTON Y TIENEN UN CABEZAL ALARGADO, EL CUAL ES RETENIDO EN UN COLECTOR EN EL PISTON POR UNA CAPSULA CIRCULAR, LA CUAL LO FIJA SOBRE EL. LA CAPSULA ESTA SOSTENIDA EN UNA POSICION ENTRE EL ANILLO DE SUJECCION RESISTENTE DESMONTABLE, EL CUAL, SE CIERRA DENTRO DE UNA RANURA Y UN ANILLO COMPRENSIBLE-O. ADEMAS AMBOS CIERRAN CONTRA LA DISPERSION Y UNA CONEXION FACILMENTE REALIZABLE ENTRE LA COMPUERTA Y EL PISTON QUE ESTAN PROVISTOS POR LA COMBINACION DE ANILLOS DE SUJECCION RESISTENTE Y ANILLOS-O.
