Abstract

Procedimiento para la compensación de distintas alturas de los moldes para fundición inyectada, para los mandos de máquinas para fundición inyectada, caracterizado porque las dos placas de fijación del molde, de las que la placa para la fijación corrediza está en unión efectiva con un codificador angular absoluto, son puestas en contacto, porque un dispositivo indicador conectado a continuación del codificador angular absoluto y este mismo son nivelados a cero y tras la aplicación de un molde de fundición inyectada ésta se ajusta a la posición de cierre y el valor indicador del dispositivo indicador es introducido por medio de un interruptor de décadas a la entrada substractora de un dispositivo comparador, en cuya segunda entrada se encuentra disponible el valor inicial del codificador angular, de tal forma que el dispositivo indicador conectado a continuación del dispositivo comparador señala el valor cero y porque tras el dispositivo comparador se encuentra conectada en sucesión la partedel mando del gobierno de la máquina de fundición inyectada, cuyas instrucciones de mando dependen de la altura del molde.
