Abstract

EN EL DISPOSITIVO HIDRAULICO PUEDE REGULARSE EL PERFIL DE VELOCIDAD Y PRESION (PERFIL) DEL MOVIMIENTO AL CERRAR EL MOLDE DE INYECCION (78) CON UN MINIMO DE TRES POSICIONES SUCESIVAS DE UNA VALVULA DE PASO 4/4 (164). EN ESAS POSICIONES CADA PISTON ESTACIONARIO (47B) DEL CILINDRO MOTOR SE RELLENA DESDE LA ZONA DEL CILINDRO DEL LADO DEL MOLDE (48). EL PERFIL DE LA PARTE DEL MOVIMIENTO DOMINANTE SE DETERMINA POR MEDIO DE UNA POSICION DE UN CONMUTADOR DIFERENCIAL CON LA QUE EL FLUIDO DE PRESION EXPULSADO DE LA ZONA POSTERIOR DEL CILINDRO (80) DEL CILINDRO MOTOR PASA POR UN CANAL BIFURCADO (68B, 83), PROVISTO DE UNA VALVULA DE RETROCESO (83'') PARA SER ALMACENADO EN LA CONDUCCION DE PRESION. ANTES Y DESPUES DE LA CONMUTACION DIFERENCIAL HAY UNA CONMUTACION DE TRANSICION DURANTE LA QUE EL FLUIDO EXPULSADO DE LA PARTE POSTERIOR DEL CILINDRO (80) REVIERTE AL TANQUE (71) A TRAVES DEL CANAL DE LA VALVULA (68). POR MEDIO DE ESTA INSTALACION SE LOGRA AUMENTAR NOTABLEMENTE EL RENDIMIENTO DE LA MAQUINA DEINYECCION PARA PLASTICOS, CON PERFILES MODERADOS DE PRESION Y VELOCIDAD DEL MOVIMIENTO DEL PORTADOR DEL MOLDE.
