Abstract

EL CILINDRO DE PLASTIFICADO DEL GRUPO DE PLASTIFICADO ESTA EQUIPADO CON UNA DOBERA (V) CERRADIZO, QUE ES DIRIGIBLE MEDIANTE UNA UNIDAD DE CILINDRO-EMBOLO HIDRAULICO (CILINDRO DE MANDO 14). EL CUERPO DE LA TOBERA (70) DE LA DOBERA (V) MUESTRA UN CANAL LIBRE DE LA TOBERA (70A) COAXIAL, QUE SE EXTIENDE PARA DESEMBOCADURA DE LA TOBERA Y PARA LA CIRCULACION DEL MATERIAL DE PLASTICO. LA AGUJA DEL INYECTOR (73), QUE BLOQUEA AL CANAL DE LA TOBERA (70A) EN LA DESEMBOCADURA DE LA TOBERA SE SOPORTA EN UN TALADRO CORREDIZO (70E), QUE SE DESVIA AL CANAL DE LA TOBERA (70A) , ANGULOS DE LA PUNTA. DE ESE MODO SE CONSIGUE QUE SEA POSIBLE UNA CIRCULACION DEL MATERIAL DE PLASTICO A TRAVES DE LA TOBERA DE CONEXION Y SE PUEDE EVITAR LA DISMINUCION DE PRESION INDICADO HABITUALMENTE CONTINUO EN LA DOBERA DE CONEXION. ADEMAS LA TOBERA (V) CERRADIZO MUESTRA TODOS LAS CARACTERISTICAS DE UNA DOBERA "ABIERTA" Y ES APLICABLE COMO TAL, CUANDO LA AGUJA DE CONEXION (73) SE ENCUENTRA EN POSICION ABIERTA PERMANENTEMENTE.
