Abstract
A method is provided for producing a die-cast part by means of a die-casting die, wherein air contained in the die-casting die is sucked out. A moisture contained in the air that is sucked out is measured. In the method, the moisture is measured while the air is sucked out. A device for producing a die-cast part, which device has a diecasting die, a suction apparatus for sucking out air present in the die-casting die, at least one sensor for detecting the moisture in the air that is sucked out, and a control apparatus for controlling the device, is designed to perform the method.
Claims14
A method for producing a diecast part, comprising:
- extracting air that is contained in a diecasting mold by suction through a first suction line and a second suction line;
- measuring a level of humidity contained in the extracted air with a sensor enclosed in a sensor structure, wherein
- the level of humidity in the extracted air is measured while the air is being extracted,
- the sensor structure is attached directly to a vacuum block, without a valve interposed between the sensor structure and the vacuum block.
An apparatus for producing a diecast part, comprising:
- a first suction line;
- a second suction line;
- a diecasting mold;
- an extraction device configured to extract air by suction and being located outside the diecasting mold;
- a moisture sensor that is part of a sensor structure and that is configured to sense a level of humidity of extracted air in only one out of the first and second suction lines;
- and
- a control device configured to control the apparatus, wherein
- the moisture sensor structure is attached directly to a vacuum block, without a valve interposed between the sensor structure and the vacuum block.
