Abstract
DE ACUERDO CON LA INVENCION, SE REALIZA UNA EXTRUSION PRELIMINAR PARA HALLAR UNA CONTRAPRESION OPTIMA QUE PUEDE PROPORCIONAR UN TAMAÑO DE SECCION PREDETERMINADO PARA PARTES RESPECTIVAS DE UN MODELO DE MOVIMIENTO DA DE UN MOLDE MOVIL; TAL MODELO ESTA DETERMINADO POR UNA FORMA DEL PRODUCTO. SE ASUME QUE EL MOLDE MOVIL ESTA COLOCADO EN UNA POSICION DA1 QUE CORRESPONDE A UNA PARTE LATERAL DE UN PRODUCTO Y UN VALOR DE UNA CONTRAPRESION BP, EN EL QUE UN PRODUCTO MOLDEADO TIENE UN TAMAÑO DE SECCION PREDETERMINADO MIENTRAS SE CAMBIAN GIROS DE UN TORNILLO DE FORMA DIFERENTE DURANTE EL MOLDEADO DE UN MATERIAL DE MOLDEADO, SE REALIZA UNA CONTRAPRESION OPTIMA BPO. UNA CONTRAPRESION OPTIMA DE UN PRODUCTO SE DETERMINA DE UNA MANERA PARA DECIDIR UN MODELO DE LA CONTRAPRESION OPTIMA BPO. TENIENDO EN CUENTA LA DIFERENCIA DE TIEMPO, UNA TEMPORIZACION, EN LA CUAL SE CAMBIA UN MODELO DEL CONJUNTO INICIAL R1 PARA LOS GIROS DEL TORNILLO, SE ESTABLECE UN PERIODO DE TIEMPO T11 A T14 POR DELANTE DE UNA TEMPORIZACION, EN LA QUE SE CAMBIA EL MODELO DA. EN UNA EXTRUSION REGULAR, SE MIDE UNA VELOCIDAD DE TOMA REAL, Y CUANDO LA VELOCIDAD MEDIDA ES DIFERENTE DE LA QUE HABIA EN EL MOMENTO DE LA EXTRUSION PRELIMINAR, SE CORRIGE EL MODELO DE MOVIMIENTO DA DEL MOLDE MOVIL. CUANDO LA CONTRAPRESION MEDIDA BP ES DESVIADA DESDE EL MODELO DE LA CONTRAPRESION OPTIMA BPO DESPUES DE QUE SE HAN EJECUTADO VARIOS CICLOS DE MOLDEADO POR EXTRUSION, SE CORRIGE EL MODELO R1 DE GIROS DEL TORNILLO.
