Abstract
UN CILINDRO DE SUJECION (22) RECIBE DE FORMA DESLIZANTE UN VASTAGO DE SUJECION (26) CUYO EXTREMO FRONTAL ESTA FIJADO SOBRE UNA PLANCHA MOVIL (20) DE, POR EJEMPLO, UNA MAQUINA DE MOLDEO POR INYECCION (21,23-25) Y QUE TIENE UNA ABERTURA DE CAMARA EN SU CARA POSTERIOR. EL INTERIOR DEL CILINDRO DE SUJECION (22) ESTA DIVIDIDO EN UNA CAMARA POSTERIOR (W) Y UNA CAMARA FRONTAL (X) POR LA SECCION DE PISTON DE GRAN DIAMETRO DEL VASTAGO DE SUJECION (26). DESDE LA PARED POSTERIOR INTERNA DEL CILINDRO DE SUJECION (22) SE PROYECTA UN PISTON DE APERTURA DE MOLDE CON UN EXTREMO FRONTAL QUE SE AJUSTA DE FORMA DESLIZABLE EN LA CAMARA EN EL VASTAGO DE SUJECION (26). EL PISTON DE APERTURA TIENE UNA SECCION DE PISTON DE GRAN DIAMETRO QUE DIVIDE LA CAMARA EN UNA CAMARA POSTERIOR (Y) Y UNA CAMARA FRONTAL (Z) QUE SE COMUNICA CON LA ATMOSFERA. UN DISPOSITIVO DE CONTROL HIDRAULICO (31,37) CONTROLA LA CONEXION DE LAS CAMARAS (X,Y Y Z) ENTRE SI Y A UNA FUENTE DE ACEITE A PRESION (40). ASI CONECTA LAS CAMARAS (X E Y)A LA CAMARA (W) PARA CIERRE A ALTA VELOCIDAD DEL MOLDE. CONECTAN LA CAMARA (W) A LA FUENTE DE ACEITE A PRESION (40) Y LIBERA LA PRESION EN LAS CAMARAS (X E Y) PARA SUJECION ESTANCA. CONECTA IGUALMENTE LA CAMARA (Y) A LA FUENTE DE ACEITE A PRESION Y CONECTA LA CAMARA (W) TANTO A LA CAMARA (X) COMO AL ELEMENTO DE LIBERACION (32) PARA ABRIR EL MOLDE. PREFERENTEMENTE, EL AREA RECEPTORA DE PRESION DE LA CAMARA (Y) DEBE SER IGUAL AL AREA DE LA SECCION TRANSVERSAL DE LA SECCION DE CAMARA DEL VASTAGO DE SUJECION (26).
