Abstract

SE DESCRIBE UN PROCEDIMIENTO Y SISTEMA PARA ACCIONAR UNA MAQUINA DE MOLDEO POR INYECCION EN DOS ETAPAS, CARACTERIZADOS PORQUE EL MOVIMIENTO DEL PISTON DE INYECCION DEL RECIPIENTE DE DESCARGA SE ENCUENTRA COORDINADO CON EL MOVIMIENTO DEL TORNILLO PLASTIFICADOR Y EL FLUJO DE MATERIAL FUNDIDO DENTRO DEL RECIPIENTE DE DESCARGA, DE MANERA QUE EL PISTON PROPORCIONE UNA MINIMA RESISTENCIA AL FLUJO DE MATERIAL FUNDIDO DENTRO DEL RECIPIENTE DE DESCARGA AL MISMO TIEMPO QUE SE EVITA LA PRODUCCION DE HUECOS O DE AIRE DENTRO DEL MATERIAL FUNDIDO. LAS FUERZAS INDESEADAS DE CIZALLAMIENTO A LOS QUE ESTA EXPUESTO EL MATERIAL FUNDIDO QUEDAN ASI REDUCIDAS, DISMINUYENDOSE DE IGUAL MODO LOS PRODUCTOS DE DEGRADACION DEL MATERIAL FUNDIDO QUE APARECERIAN SI SE ACTUARA DE OTRO MODO.
