Abstract

PARA LA COLADA POR INYECCION DE PIEZAS DE MOLDEO A PARTIR DE PLASTICO INYECTABLE SE PROPONE UN PROCEDIMIENTO SEGUN EL CUAL, EN PRIMER LUGAR, EL MATERIAL PLASTICO PROCEDENTE DEL CILINDRO HELICOIDAL 10 DE UNA EXTRUSORA 1 SE PLASTIFICA EN UNA ANTECAMARA HELICOIDAL 9 Y, A CONTINUACION, LA ANTECAMARA LLENA 9 SE BLOQUEA MEDIANTE UN CIERRE 11 QUE EVITA EL RETROCESO DEL CALDO PLASTICO AL CILINDRO HELICOIDAL 10, SIENDO IMPULSADO A CONTINUACION EL CALDO TERMOPLASTICO DESDE LA ANTECAMARA HELICOIDAL 9 AL INTERIOR DEL MOLDE DE INYECCION 2, Y, SEGUN EL CUAL, EL TRANSCURSO DEL PROCESO DE INYECCION, POR EJEMPLO, EN LO REFERENTE A LA VELOCIDAD A LO LARGO DEL CAMINO A RECORRER, VIENE DETERMINADO POR EL PERFIL DE INYECCION PREVISTO O PREVISIBLE. PARA HACER MINIMA LA DESVIACION DEL PESO ESTANDAR DE LA PIEZA PRODUCIDA Y PODER CONSEGUIR UNA MEJORA SUSTANCIAL DE LA CALIDAD DE LA MISMA, ES IMPORTANTE QUE EL PUNTO DE ARRANQUE PARA EL PERFIL DE INYECCION 5, CUYO VALOR NOMINAL HA SIDO DADO ANTERIORMENTE, SE DETERMINEO SE FIJE UNA VEZ QUE HAYA SIDO ACTIVADO EL CIERRE DEL FLUJO DE RETROCESO DEL CALDO PLASTICO Y/O CON LA APERTURA DE LA BOQUILLA DE INYECCION 12 HACIA EL MOLDE DE INYECCION 2.
