Abstract

PROCEDIMIENTO DE FABRICACION EN MOLDES DE PATILLAS PARA GAFAS, CON REFUERZO METALICO FLEXIBLE QUE NO SOBRESALE DEL PLASTICO EN AMBOS EXTREMOS DE LA PATILLA. SE COLOCAN UNOS REFUERZOS METALICOS (2) EN LOS MOLDES (1), SUJETOS EN UNO DE SUS EXTREMOS (3) POR PIEZAS DE APRIETE (4). CADA UNO DE DICHOS REFUERZOS, EN SU OTRO EXTREMO, ESTA UNIDO A UN ELEMENTO DE TRACCION (6), A TRAVES DE UN PUNTO DEBIL (7) QUE CONSISTE EN UN ESTRANGULAMIENTO CONICO, PARA EVITAR QUE DURANTE EL PROCESO DE INYECCION DEL MATERIAL PLASTICO EN EL MOLDE SE PRODUZCA UN DESPLAZAMIENTO DEL REFUERZO METALICO.
