Abstract

EL MOLDE (3) COMPRENDE UNA MITAD DE MOLDE ESTACIONARIA (5) Y UNA MITAD DE MOLDE MOVIL (6) QUE COOPERA, DURANTE SU USO, CON LA MITAD DEL MOLDE ESTACIONARIO (5). LA MITAD DEL MOLDE MOVIL (6) COMPRENDE UNA PARED DE SOPORTE MOVIL (13) QUE LLEVA UN TROQUEL (14) FIJADO MEDIANTE PLACAS DE ANCLAJE (15). UNA LAMINA (17) QUE SOPORTA LOS RELIEVES EN NEGATIVO DE LA PIEZA OPTICA A REPRODUCIR SE ANCLA DE FORMA MECANICA Y MAGNETICA (23, 25, 28) AL TROQUEL (14), ESTE ULTIMO ESTA HECHO DE MATERIAL NO MAGNETICO Y ALOJA INSERTOS DE MATERIAL MAGNETIZABLE (23). LA MITAD DEL MOLDE MOVIL (6) SOPORTA ADEMAS GENERADORES DE CAMPOS MAGNETICOS (25) QUE MAGNETIZAN LOS INSERTOS (23) Y GARANTIZAN UNA BUENA ADHERENCIA DE LA LAMINA (17) AL TROQUEL (14).
