Abstract
The present invention relates to a filling injector and to a method for operating such a filling injector. The filling injector has a sensor for detecting a predetermined detection position of a closing piston unit and a counting device for counting the number of detection positions of the closing piston unit in which it is situated in the predetermined detection position. By means of this, when a predetermined number of detection positions is reached, a maintenance signal can be emitted and the maintenance interval can be adapted to the actual use of the filling injector.
Claims25
A filling injector for a mold having an injector housing, which has a cylindrical cavity in which a closing piston unit is supported in movable fashion;
- the injector housing has a supply for plastic granules leading to the cavity and at an end oriented toward the mold, has a mold opening for supplying the plastic material to a mold and
- in a closed position, the closing piston unit is slid so far forward that it closes the mold opening and in an open position, is retracted from the cylindrical cavity at least in the region between the supply and the mold opening, wherein
- in or on the injector housing:
- 1) a sensor is provided for detecting a predetermined detection position of the closing piston unit and 2) a counting device is provided for counting the number of detection positions of the closing piston unit in which it is situated in the predetermined detection position;
- wherein the counting device functions autonomously and is provided in or on the injector housing.
