Abstract

EN UN PROCEDIMIENTO PARA FABRICAR MOLDES DE PLASTICO LAMINADO, QUE CONSTAN DE UNA CAPA BASE DE MATERIAL SINTETICO TERMOPLASTICO Y AL MENOS UNA CAPA DE CUBIERTA (7), ENTRE UNA MITAD INFERIOR 2 Y UNA SUPERIOR 5 DEL MOLDE SE PRENSA MATERIAL SINTETICO TERMOPLASTICO FLUIDO 12 COMO CAPA BASE CON LA CAPA DE CUBIERTA COLOCADA ENTRE LAS MITADES DEL MOLDE. PARA IMPEDIR QUE AL PRENSAR EL MATERIAL SINTETICO TERMOPLASTICO FLUIDO O LA MASA EN FUSION SE MODIFIQUE CONSTANTEMENTE LA CAMARA HUECA DEL MOLDE Y CORRESPONDIENTEMENTE LA MASA EN FUSION DEBA MODIFICAR DE NUEVO EN DETERMINADAS SECCIONES DEL MOLDE SU SENTIDO DE FLUJO, CON LO QUE AL PRENSAR CON LA CAPA DE CUBIERTA PUDIERAN RESULTAR PLIEGUES Y DEFORMACIONES NO DESEADAS, SE PROPONE QUE LAS MITADES DEL MOLDE SE CONDUZCAN PRIMERO A SU POSICION FINAL SITUANDO EN MEDIO LA CAPA DE CUBIERTA E INCLUYENDO LA CAMARA HUECA DEL MOLDE QUE REPRESENTA LA CAPA BASICA TERMINADA. A CONTINUACION TIENE LUGAR EL PROCESO DE PRENSADO DE TAL MODO QUE UNA PARTE QUE REPRESENTAUN CUERPO DE DESPLAZAMIENTO 9 DE LA MITAD INFERIOR DEL MOLDE 2, SE PRESIONA DESDE UNA POSICION BAJADA, EN LA QUE ESTA FORMADA LA CAVIDAD 11 QUE ALOJA LA MASA EN FUSION, MEDIANTE UN EMBOLO ELEVADOR 10 A UNA POSICION SUPERIOR, EN LA QUE LA SUPERFICIE DEL CUERPO DE DESPLAZAMIENTO ESENCIALMENTE REMATA ENRASADO CON LA SUPERFICIE DEL MOLDE DE LA MITAD INFERIOR DEL MISMO.
