Abstract

PROCEDIMIENTO PARA EXTRAER Y BLOQUEAR UNA MASA EN FUSION, ESPECIALMENTE DE PLASTICO, CON UN DISPOSITIVO DE FUNDICION (1) CALEFACCIONABLE, PROVISTO DE UNA VALVULA DE CIERRE (3), QUE ACTUA COMO DISTRIBUIDOR DE LA MASA EN FUSION, DESDE EL CUAL LA MASA EN FUSION FLUYE A UNA PLACA DE TOBERAS (10), QUE DISTRIBUYE LA MASA EN FUSION MEDIANTE TOBERAS (14) EN UNA GRAN CANTIDAD DE CHORROS, EN DONDE LA TEMPERATURA DEL DISPOSITIVO DE FUNDICION Y LA PLACA DE TOBERAS SE REGULA POR SEPARADO Y SE CIERRA LA VALVULA DE CIERRE PARA DETENER LA MASA EN FUSION Y LA PLACA DE TOBERAS ESTA HERMETICAMENTE CERRADA MEDIANTE UNA TAPA (18). PARA EXTRAER LA MASA EN FUSION CON LA VALVULA DE CIERRE ABIERTA SE MANTIENE ESENCIALMENTE A UN MISMO NIVEL LA TEMPERATURA DEL DISPOSITIVO DE FUNDICION Y DE LA PLACA DE TOBERAS, PARA DETENER LA MASA EN FUSION CON LA VALVULA DE CIERRE CERRADA SE LLEVA LA PLACA DE TOBERAS A UNA TEMPERATURA SITUADA POR ENCIMA DE LA TEMPERATURA DE SOLIDIFICACION DEL MATERIAL FUNDIDO. AL CERRAR LA VALVULA DE CIERRE SE COLOCA LA TAPA ENFRIADA A UNA TEMPERATURA CONSIDERABLEMENTE INFERIOR A LA TEMPERATURA DE SOLIDIFICACION EN LA PLACA DE TOBERAS, EN LA QUE FLUYE UN RESTO DE MASA EN FUSION Y CERRANDO DE MODO HERMETICO LAS BOQUILLAS DE LAS TOBERAS EN ESTADO SOLIDIFICADO.
