Abstract

Perfeccionamientos en los dispositivos de mando para máquinas de moldeado por inyección, en que, para la demanda en dependencia del recorrido, de las órdenes de mando, se han previsto un sistema de medida de recorrido unido a una pieza mecánica móvil de la máquina de moldeado por inyección, y un dispositivo comparador, que en caso de coincidencia de un valor real de recorrido emitido por el sistema de medida del trayecto, con un valor indicado, emite una orden de mando que permita hasta la próxima coincidencia, caracterizados porque el sistema de medida angular es un codificador angular absoluto y un número de conmutadores de décadas equivalente al número de órdenes de mando dependientes del recorridos se conecta a las entradas del dispositivo comparador de modo que a través del conmutador de décadas puede emitirse respectivamente una orden de mando dependiente del recorrido.
