Su vida \u00fatil determina directamente la frecuencia de mantenimiento, el costo del molde y el tiempo de inactividad de la producci\u00f3n.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Durante la operaci\u00f3n, el metal fundido entra en la cavidad a presiones de 20\u2013150 MPa, y en casos extremos alcanza los 700 MPa. Al mismo tiempo, los insertos est\u00e1n expuestos a un calentamiento superficial r\u00e1pido seguido de un enfriamiento forzado. Esto crea gradientes t\u00e9rmicos pronunciados entre la superficie y el n\u00facleo, lo que provoca repetidas expansiones y contracciones en cada ciclo.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">En estas condiciones, la falla es impulsada por mecanismos identificables en lugar de da\u00f1os aleatorios. En producci\u00f3n, los insertos suelen fallar de una de las siguientes maneras:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>P\u00e9rdida de material superficial causada por el flujo de metal fundido a alta velocidad (lavado)<\/li>\n\n<li>Adhesi\u00f3n entre la aleaci\u00f3n fundida y la superficie de la herramienta (soldadura)<\/li>\n\n<li>Redes de grietas superficiales por tensi\u00f3n t\u00e9rmica c\u00edclica (agrietamiento t\u00e9rmico)<\/li>\n\n<li>Fractura s\u00fabita debido a concentraci\u00f3n de tensiones o choque t\u00e9rmico<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Por lo tanto, la selecci\u00f3n del acero para herramientas debe basarse en cu\u00e1l modo de falla domina su proceso, no en las propiedades generales del material.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" style=\"font-size:28px\">L\u00f3gica de selecci\u00f3n de n\u00facleos<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Para los n\u00facleos e insertos de fundici\u00f3n a presi\u00f3n, la selecci\u00f3n del material est\u00e1 determinada por si la falla est\u00e1 dominada por el ablandamiento t\u00e9rmico o por el agrietamiento.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Si el material pierde resistencia a temperatura, la erosi\u00f3n y la deformaci\u00f3n se aceleran.<br>Si el material carece de tenacidad, se producir\u00e1 agrietamiento antes de que el desgaste sea relevante.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">El grado correcto se elige identificando el mecanismo de falla principal.<\/p>\n\n\n\n<div class=\"wp-block-group has-background is-layout-constrained wp-container-core-group-is-layout-1b2ccf01 wp-block-group-is-layout-constrained\" style=\"border-radius:10px;background-color:#f4f8ff;margin-bottom:22px;padding-top:22px;padding-right:26px;padding-bottom:20px;padding-left:26px\">\n\n<h3 class=\"wp-block-heading\" style=\"font-size:22px\">Fatiga t\u00e9rmica (agrietamiento t\u00e9rmico)<\/h3>\n\n\n<p class=\"wp-block-paragraph\">Cuando los insertos fallan por agrietamiento superficial, la causa ra\u00edz es la tensi\u00f3n t\u00e9rmica c\u00edclica. La superficie se expande con el calor mientras el interior la restringe, creando tensiones de tracci\u00f3n y compresi\u00f3n repetidas.<\/p>\n\n\n<p class=\"wp-block-paragraph\">Los materiales con microestructura estable a temperatura elevada retrasan la iniciaci\u00f3n de grietas y reducen la velocidad de propagaci\u00f3n de las grietas.<\/p>\n\n<\/div>\n\n\n\n<div class=\"wp-block-group has-background is-layout-constrained wp-container-core-group-is-layout-1b2ccf01 wp-block-group-is-layout-constrained\" style=\"border-radius:10px;background-color:#f4f8ff;margin-bottom:22px;padding-top:22px;padding-right:26px;padding-bottom:20px;padding-left:26px\">\n\n<h3 class=\"wp-block-heading\" style=\"font-size:22px\">Resistencia en caliente y resistencia al ablandamiento<\/h3>\n\n\n<p class=\"wp-block-paragraph\">Si los insertos muestran deformaci\u00f3n pl\u00e1stica o desgaste superficial r\u00e1pido, el factor limitante es la resistencia a alta temperatura. El material debe retener la dureza a la temperatura de operaci\u00f3n para resistir la erosi\u00f3n y mantener la estabilidad dimensional.<\/p>\n\n\n<p class=\"wp-block-paragraph\">Esto se vuelve cr\u00edtico en condiciones de fundici\u00f3n de alta velocidad o alta temperatura.<\/p>\n\n<\/div>\n\n\n\n<div class=\"wp-block-group has-background is-layout-constrained wp-container-core-group-is-layout-1b2ccf01 wp-block-group-is-layout-constrained\" style=\"border-radius:10px;background-color:#f4f8ff;margin-bottom:22px;padding-top:22px;padding-right:26px;padding-bottom:20px;padding-left:26px\">\n\n<h3 class=\"wp-block-heading\" style=\"font-size:22px\">Resistencia a la fractura (tenacidad)<\/h3>\n\n\n<p class=\"wp-block-paragraph\">Cuando la falla aparece como agrietamiento s\u00fabito, especialmente en secciones delgadas o geometr\u00edas agudas, la tenacidad se convierte en el factor controlante.<\/p>\n\n\n<p class=\"wp-block-paragraph\">Aumentar la dureza en este caso generalmente acelera la falla en lugar de resolverla. La selecci\u00f3n del material debe orientarse hacia grados con mayor resistencia a la fractura.<\/p>\n\n<\/div>\n\n\n\n<div class=\"wp-block-group has-background is-layout-constrained wp-container-core-group-is-layout-1b2ccf01 wp-block-group-is-layout-constrained\" style=\"border-radius:10px;background-color:#f4f8ff;margin-bottom:22px;padding-top:22px;padding-right:26px;padding-bottom:20px;padding-left:26px\">\n\n<h3 class=\"wp-block-heading\" style=\"font-size:22px\">Resistencia a la soldadura<\/h3>\n\n\n<p class=\"wp-block-paragraph\">En la fundici\u00f3n a presi\u00f3n de aluminio, el aluminio fundido reacciona con el hierro, formando capas intermet\u00e1licas. Esto provoca adherencia, desgarro y da\u00f1o superficial durante la expulsi\u00f3n.<\/p>\n\n\n<p class=\"wp-block-paragraph\">Este comportamiento est\u00e1 influenciado principalmente por la composici\u00f3n del material base y se vuelve m\u00e1s severo bajo exposici\u00f3n a alta temperatura y ciclos largos.<\/p>\n\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\" style=\"font-size:28px\">Aceros para herramientas recomendados<\/h2>\n\n\n\n<div class=\"wp-block-group has-background is-layout-constrained wp-container-core-group-is-layout-1b2ccf01 wp-block-group-is-layout-constrained\" style=\"border-radius:10px;background-color:#f4f8ff;margin-bottom:22px;padding-top:22px;padding-right:26px;padding-bottom:20px;padding-left:26px\">\n\n<h3 class=\"wp-block-heading\" style=\"font-size:22px\">H13 (1.2344 \/ SKD61)<\/h3>\n\n\n<p class=\"wp-block-paragraph\">H13 es la opci\u00f3n est\u00e1ndar para la mayor\u00eda de los insertos de fundici\u00f3n a presi\u00f3n porque ofrece una combinaci\u00f3n equilibrada de resistencia a la fatiga t\u00e9rmica y tenacidad.<\/p>\n\n\n<p class=\"wp-block-paragraph\">Funciona de manera confiable bajo calentamiento y enfriamiento c\u00edclicos y puede operar en condiciones de enfriamiento por agua sin agrietarse de inmediato.
