Abstract

SE PRESENTA UN SISTEMA HIDRAULICO CONTROLADO MEDIANTE UN COMPUTADOR PARA UNA MAQUINA DE MOLDEADO DE INYECCION DE PLASTICO TIPO CAZONETE DEL TIPO DE LAS QUE COMPRENDE UNA ESTRUCTURA DE INYECCION Y UN MONTAJE DE SUJECCION DEL MOLDE. EL SISTEMA HIDRAULICO COMPRENDE UNA PRIMERA BOMBA DE BAJO VOLUMEN Y UNA SEGUNDA BOMBA DE ALTO VOLUMEN CONECTADAS ENTRE UN DEPOSITO DE FLUIDO HIDRAULICO Y UN CONTROL MULTIPLE DE PRESION Y DE FLUJO. LA SALIDA DEL CONTROL MULTIPLE DE PRESION Y DE FLUJO SE CONECTA A UN CONTROL A SU VEZ CONECTADO A UN MANEJADOR DE INSTRUMENTOS DEL MONTAJE DE INYECCION. LA SALIDA DEL CONTROL MULTIPLE DE PRESION Y DE FLUJO TAMBIEN SE CONECTA A UN CONTROL MULTIPLE DE SUJECCION, A SU VEZ CONECTADO AL MANEJADOR DEL CILINDRO DEL MONTAJE DE SUJECCION. UN AISLAMIENTO SE CONECTA ENTRE EL CONTROL DE PRESION Y DE FLUJO Y DEL CONTROL DE SUJECCION. UNA TERCERA BOMBA DE BAJO VOLUMEN SE CONECTA ENTRE EL DEPOSITO Y EL AISLAMIENTO. EL AISLAMIENTO SE CONECTA TAMBIEN AL DEPOSITO. CUANDO NO FUNCIONA,EL AISLAMIENTO CONECTA LA SALIDA DE CONTROL DE PRESION Y DE FLUJO DIRECTAMENTE AL CONTROL DE SUJECCION Y HACE RECIRCULAR LA TERCERA BOMBA HACIA EL DEPOSITO. CUANDO LA MAQUINA ESTA PREPARADA PARA REALIZAR CICLOS SECUENCIALES TALES COMO EL MOLDEADO DE INYECCION CONVENCIONAL O EL ACUÑAMIENTO CONVENCIONAL. CUANDO FUNCIONA, EL AISLAMIENTO DESCONECTA LA SUJECCION MULTIPLE DEL CONTROL DE PRESION Y DE FLUJO Y CONECTA LA TERCERA BOMBA AL CONTROL DE SUJECCION, POSIBILITANTO QUE LA MAQUINA REALICE UN CICLO DE ACUÑAMIENTO CON SUJECCION INDIVIDUAL O SIMULTANEA Y CONTROL DE INYECCION, Y PRECISA DE UNA POSICION REPETIBLE Y UN CONTROL DE VELOCIDAD DEL PASO DE ACUÑAMIENTO.
