Abstract

UN MOLDE DE MATERIAL PLASTICO PARA FUNDIR LENTES DE CONTACTO A PARTIR DE MATERIAL CURABLE COMPRENDE MIEMBROS DE MOLDE DESCARTABLE MACHO Y HEMBRA (20, 22, 50, 51) QUE DEFINEN UNA CAVIDAD DE MOLDE Y CADA UNO DISPONE DE UNA SUPERFICIE CURVA (21, 23, 52, 54) PARA MODLEAR UNA RESPECTIVA SUPERFICIE OPTICA DE LA LENTE DE CONTACTO, EL MIEMBRO DE MOLDE MACHO DISPONE DE UN HOMBRO (26, 53) QUE PUEDE AJUSTARSE DESLIZABLEMENTE CON UNA SUPERFICIE GENERALMENTE CILINDRICA, POR EJEMPLO FRUSTO-CONICA, (25, 55) EN EL MIEMBRO DE MOLDE DE CARA HEMBRA PARA PERMITIR UN MOVIMIENTO RELATIVO DEL MIEMBRO DE MOLDE DURANTE EL CURADO SIN AFECTAR SUBSTANCIALMWEWNTE LA CALIDAD OPTICA DE LAS SUPERFICIES OPTICAS MODLEADAS. EL HOMBRO DE AJUSTE DE DESLIZAMIENTO Y LA SUPERFICIE HEMBRA SON RELATIVAMENTE SIMPLES DE MOLDEAR CON PRECISION PERMITIENDO QUE EL BORDE (29) DE LA FUTURA LENTE FUNDIDA SE FORME CON CIERTA PRECISION Y CONFIABILIDAD
