Abstract
APARATO PARA LA FABRICACION DE OBJETOS CON ESTRUCTURA CELULAR EN UN MOLDE. CONSTA DE DOS MEDIAS CONCHAS (1A Y 1B), ARTICULADAS SOBRE UN EJE (2), QUE INCLUYEN SENDAS BRIDAS PERIFERICAS (5A,5B) MANTENIDAS POR DISPOSITIVOS DE ANCLAVAMIENTO (6), QUE DELIMITAN UNA CAMARA DE DEPRESION ANULAR (8). LA MEDIA CONCHA (1B) TIENE UN ORIFICIO DE COLADA (14) EN EL QUE SE PUEDE SITUAR Y MEDIANTE EL TUBO INYECTOR (19), UNA CABEZA DE COLADA (15) ARTICULADA EN UN BASTIDOR FIJO (17) QUE RECIBE LOS COMPONENTES DEL PRECURSOR DE LA MATERIA SINTETICA DESTINADA A FORMAR ULTERIORMENTE LA MATERIA CELULAR. EL APARATO CONSTA TAMBIEN DE UN DETECTOR DE NIVEL (21), SITUADO EN UNA CAVIDAD (20) DE LA PARED DE LA MEDIA-CONCHA (1B), QUE SUMINISTRA UNA SEÑAL CUANDO LA ESPUMA ALCANZA UN DETERMINADO NIVEL. EL APARATO PUEDE ESTAR COMPUESTO POR UN GRUPO DE MOLDES MONTADOS EN CARRUSEL Y ALIMENTADOS POR UNA MISMA CABEZA DE COLADA.
