Abstract

UN MOLDE DE FUNDICION PARA UN APARATO DE COLADA DE BAJA PRESION PUEDE ABRIRSE Y CERRARSE PARA FORMAR EN SU CAVIDAD (7() QUE SE RELLENA CON METAL FUNDIDO PARA FORMAR UN PRODUCTO COLADO. EL MOLDE DE COLADA COMPRENDE UN MOLDE SUPERIOR (3) DE METAL, UN MOLDE INFERIOR (2) DE METAL Y UN MOLDE DE ARENA (4) QUE ESTA DISPUESTO ENTRE LOS MOLDES SUPERIOR E INFERIOR Y FORMA UNA PARTE DE LA CAVIDAD (7). UNA PARED SUPERIOR DE LA CAVIDAD SE FORMA POR UNA SUPERFICIE INFERIOR (3A) DEL MOLDE SUPERIOR, AL MENOS UNA PARTE DE UNA PARED LATERAL DE LA CAVIDAD SE FORMA POR EL MOLDE DE ARENA DE MANERA QUE EL MOLDE SUPERIOR ENTRA EN CONTACTO CON EL MATERIAL FUNDIDO DE RELLENO EN LA CAVIDAD (7) EN UN AREA MAYOR QUE EL MOLDE INFERIOR.
