Abstract

UNA PRENSA PARA MOLDEAR ARTICULOS POLIMERICOS DE POLIURETANO TERMOPLASTICO COMPRENDE TRES ESTACIONES DE TRABAJO DISPUESTAS LADO CONTRA LADO Y QUE INCLUYEN UNA ESTACION DE MOLDEADO CENTRAL (20) Y DOS ESTACIONES LATERALES (30A, 30B) PARA EL ENFRIAMIENTO PARA LA EXTRACION DE LOS ARTICULOS MOLDEADOS. DOS MOLDES (70A, 70B) ESTAN CONECTADOS RIGIDAMENTE UNO CONTRA OTRO Y CONTROLADOS POR UN COMPRESOR (75) QUE ALTERNATIVAMENTE MUEVE LOS MOLDES DESDE LA ESTACION DE MOLDEADO HASTA CUALQUIERA DE LAS ESTACIONES DE ENFRIAMIENTO Y DE EXTRACCION. UN PRIMER PRESIONADOR (22) EN LA ESTACION DE MOLDEADO CENTRAL APLICA LA PRESION NECESARIA PARA LA INYECCION DEL MATERIAL, MIENTRAS QUE UN PRENSADOR AUXILIAR (50, 60) DISPUESTO EN CADA ESTACION APLICA UNA PRESION SECUNDARIA REDUCIDA A LOS MOLDES EN EL FINAL DEL PASO DE INYECCION, DURANTE EL MOVIMIENTO DE TRANSLACION DEL MOLDE Y DURANTE EL PASO DE ENFRIAMIENTO.
