Abstract

PROCEDIMIENTO PARA LA FABRICACION DE CUERPOS DE MOLDEADO DE SOPLADO DE MATERIAL TERMOPLASTICO A PARTIR DE UNA PIEZA MOLDEADA (V, V1) EXTRUSIONADA DE FORMA INTERMITENTE CON UN ACUMULADOR (K), DONDE AL MENOS UNA CAMARA (P) DE ACUMULACION QUE MUESTRA UNA TOBERA (18) DE MOLDEADO, QUE SE ABRE A INTERVALOS, SE RELLENA A PARTIR DE UN EXTRUSIONADOR (E, E1) CON UNA CORRIENTE DE MATERIAL. UN EMBOLO (38) DISPUESTO EN LA CAMARA (P) DE ACUMULACION EXTRUSIONA ESTA CANTIDAD DE MATERIAL DETERMINADA PREVIAMENTE A TRAVES DE LA TOBERA DE MOLDEO, AJUSTANDOSE LA CORRIENTE DE MATERIAL QUE APARECE A PARTIR DEL EXTRUSIONADOR (E, E1) CON UNA RELACION DE TRANSPORTE-RELLENO VOLUMETRICA CONSTANTE CON RESPECTO A LA RELACION DE TRANSPORTADOR-EXTRUSIONADOR SUFICIENTE PARA EL CABEZAL ACUMULADOR. EL CABEZAL (K) ACUMULADOR PERMANENTE SE GUIA CON UNA RELACION DE TRANSPORTE-RELLENO VOLUMETRICO CONSTANTE SEGUN REQUIERE EL INTERVALO DE SALIDA CONTRA UNA SITUACION ESTANCADA. EL DISPOSITIVO ADECUADO PARA LA REALIZACION DEL PROCEDIMIENTO MUESTRA, ENTRE EL CABEZAL (K) ACUMULADOR Y CADA EXTRUSIONADOR (E) COMO AGREGADO DE RELLENO PARA LA CAMARA (P) DE ACUMULACION, UNA BOMBA (S) DE COLADA QUE TRANSPORTA DE FORMA PERMANENTE EL VOLUMEN ACCIONADO DE MASA CON UNA VELOCIDAD CONSTANTE.
