Abstract

EN LA PRESENTE INVENCION SE PRESENTA UN METODO PARA EL MOLDEADO DE HOJAS DE VIDRIO EN CONFIGURACIONES MUY HUNDIDAS MEDIANTE LA UTILIZACION DE UN MOLDE PERFILADOR INFERIOR Y UN MOLDE FORMADOR SUPERIOR AL TIEMPO QUE SE MINIMIZA EL MARCADO DE LAS HOJAS POR PARTE DE LOS MOLDES FORMADORES. EL MOLDE PERFILADOR INCLUYE UN RIEL DE SOPORTE QUE GENERALMENTE SE CORRESPONDE CON LA CURVATURA DESEADA DE UNA PORCION PERIFERICA DE LAS HOJAS A FORMAR Y QUE SOPORTA LAS HOJAS DE VIDRIO CONFORME SON CALENTADAS Y HUNDIDAS POR GRAVEDAD PARA DARLES UNA FORMA PRELIMINAR. A CONTINUACION SE MUEVEN EL MOLDE PERFILADOR Y EL MOLDE SUPERIOR, UNO RESPECTO AL OTRO, A UNA POSICION EN LA QUE BIEN LOS MOLDES QUEDAN MUY CERCA ENTRE SI O BIEN A UNA EN QUE SE PRESIONA AL MOLDE SUPERIOR CONTRA LAS HOJAS DE VIDRIO. A CONTINUACION SE DIRIGE UN GAS A PRESION DESDE EL MOLDE HASTA AL MENOS UNA DE LAS PORCIONES CENTRALES NO SOPORTADAS DE LAS HOJAS CON UNA FORMA PRELIMINAR, PARA EMPUJAR A ESTAS PORCIONES NO SOPORTADAS HACIA ABAJO Y DARFORMA A LAS HOJAS HASTA OBTENER LA CONFIGURACION DESEADA.
