Abstract

La invención se refiere a un dispositivo (1) y a un procedimiento para la medición de la humedad en moldes de fundición a presión (24), cuyo espacio hueco del molde (25) está conectado a través de un conducto de ventilación (31) con un dispositivo de ventilación (28). El dispositivo (1) configurado de manera modular puede conectarse con el conducto de ventilación (31) y comprende una disposición de sensores (S), mediante la cual puede medirse la humedad de gases extraídos del espacio hueco del molde (25). La disposición de sensores (S) presenta un emisor (7) que emite radiación electromagnética y un receptor (14) que detecta radiación electromagnética. Debido a los valores de medición determinados durante el proceso de evacuación, puede determinarse si la cantidad de una mezcla de agua y medio desmoldeador, que se inyecta antes del proceso de fundición propiamente dicho en el espacio hueco del molde (25), ha de modificarse.

la pieza de fundición e impide el pegado del metal al molde o a las paredes del espacio hueco del molde 25. La instalación de control 29 está conectada eléctricamente con el dispositivo 1, así como con los componentes 23, 24, 26, 27, 28, lo que se indica mediante líneas discontinuas.
Un ciclo de medición para la determinación de la humedad en el molde de fundición a presión 24 se produce aproximadamente de la siguiente manera. Con el molde de fundición a presión 24 abierto, se inyecta mediante el cabezal de rociado 26 la mezcla de agua y medio desmoldeador en el espacio hueco del molde 25. Junto con otros parámetros, la temperatura del molde de fundición a presión y la cantidad de mezcla de agua y medio desmoldeador inyectada, determina particularmente si se evapora todo el agua o solo una parte de ella. Tras la inyección de la mezcla se cierra el molde de fundición a presión 24. Antes de que comience el ciclo de medición propiamente dicho, se lleva a cabo un llamado ajuste a cero de la disposición de sensores S del dispositivo 1, para que por ejemplo, no entre un ensuciamiento eventual de los discos de vidrio en el resultado de la medición. Después de ello se evacua el espacio hueco del molde 25, en cuanto que se extraen mediante el tanque de vacío 28 a través del conducto de ventilación 31 y la válvula de ventilación 27 abierta, gases del espacio hueco del molde 25 y los canales y conductos 30, 31 conectados con éste. Con el inicio del proceso de extracción, se inicia entonces el ciclo de medición propiamente dicho, en cuanto que se mide o bien de manera continua o se llevan a cabo una pluralidad de mediciones individuales. En este caso se mide cómo de grande es la debilitación de la señal emitida o cómo de fuerte es la señal detectada por el receptor. Debido a la debilitación o a la elevación de la señal recibida, puede sacarse entonces una conclusión sobre cuál es la proporción de partículas de agua y/o vapor en el gas fluyente (aire). Para mantener lo más reducida posible la influencia de posibles fuentes de errores, como por ejemplo gases externos, humo, etc., se mide de manera particularmente preferida en el rango de longitud de onda infrarroja de entre 930 y 950 nm (nanómetros).
Preferiblemente un ciclo de medición consiste en una pluralidad de mediciones individuales. Debido a los valores de medición, como también al transcurso, pueden sacarse conclusiones en relación con la humedad en el molde de fundición. Un ciclo de medición también puede consistir no obstante, en una pluralidad de mediciones individuales, por ejemplo en 1000 mediciones individuales, calculándose a partir de una cantidad determinada de mediciones individuales, por ejemplo, a partir de 10 mediciones individuales, el valor medio y teniéndose en cuenta éste entonces como magnitud de medición, de manera que finalmente se tendrían en cuenta 100 puntos de medición. De esta manera puede minimizarse por ejemplo, la influencia de partículas sólidas individuales o más grandes, que se encuentran en el gas fluyente.
Dependiendo del resultado de la medición, puede modificarse para procesos de medición posteriores, la cantidad de mezcla de agua y medio desmoldeador a inyectar. En el caso de una proporción de agua demasiado grande, se reduce la cantidad de mezcla de agua y medio desmoldeador a inyectar, pudiéndose alargar en su caso también el proceso de extracción.
Habitualmente al principio de un ciclo de fundición, en el que por ejemplo, han de colarse varios miles de piezas, se lleva a cabo antes de cada proceso de fundición un ciclo de medición y eventualmente se modifica la cantidad de la mezcla de agua y medio desmoldeador a inyectar, y se hace durante tanto tiempo, hasta que se han estabilizado los parámetros determinantes como particularmente la temperatura del molde y la humedad del espacio hueco del molde a una medida predeterminada, teniendo que garantizarse naturalmente, que tras la evaporación del agua queda una película de medio desmoldeador continua. Después de ello, puede llevarse a cabo entonces a intervalos predeterminados, por ejemplo, cada hora o tras cada décimo proceso de fundición, un proceso de medición y modificarse debido a los valores de medición medidos o determinados eventualmente los parámetros. También puede modificarse obviamente la cantidad de la mezcla a aplicar localmente dentro del molde de fundición o del
