Definitions
- the present invention relates to a method and an apparatus for producing a die-cast part.
- the cycle often begins with the application of a release or lubricant which is also intended to prevent the material from adhering to the metal of the mold.
- Dry blowing of the mold may leave a residual moisture in the mold.
- Residual moisture in die casting molds can also enter the mold cavity during casting, such as by vacuum, defective sprayers, leaks, etc., and can lead to increased porosity in the casting and, in the worst case, rejects. If this residual moisture is detected only in the case of casting problems or increased rejects, it is possible to react to moisture problems late. There are then possibly some parts already produced, which can lead to increased waste costs and possibly supply problems.
- Barrier valves have prevailed in the die casting mold.
- a measurement of the environmental parameters such as residual moisture, temperature and / or pressure is carried out within the closed reference space.
- the measured values are used to control the casting process.
- To the specified response time of To reach sensors which according to DE 196 28 870 A1 is about 15 seconds, the measurement is carried out within a time range of 10-30 seconds.
- the cycle time is limited down by the time required for the measurement.
- a measuring time of 10 seconds With a measuring time of 10 seconds, a maximum of 360 shots per hour, with a measuring time of 30 seconds a maximum of 120 shots per hour can be driven.
- lower cycle times of up to 1000 / hour http://de.wikipedia.org wiki / die casting) can not be exploited.
- the invention is based on the object to avoid the disadvantages of the prior art and to provide an improved method and a corresponding device for producing a die-cast part.
- a method for producing a die-cast part by means of a die-casting mold, wherein in the
- Suctioned air is sucked, wherein a moisture contained in the extracted air is measured.
- the moisture is measured during the suction.
- the suction (and measuring) is preferably done before injection of the casting material. However, it may be desirable for suction and pouring to at least partially overlap. In this case, it is advantageous if the suction line is not shut off to form a reference space, because only so is an overlap of suction and pouring possible. It may also be advantageous if, during the pouring of casting material, the suction line is free, so that any air still contained in the pressure casting mold can be forced out of the die by the suction line. This is only possible if the suction line is not shut off.
- the measured humidity is preferably a relative humidity, but may also be absolute humidity. The measurement is preferably carried out by a suitable sensor. It is understood that air is just one example of any gas contained in the die and capable of absorbing moisture.
- the method may be developed in a preferred embodiment such that in addition a temperature and / or a pressure of the extracted air are measured. From humidity and temperature can on dew point, Absolute humidity, enthalpy and vapor pressure are closed.
- Pressure measurement also allows better control of the vacuum.
- the method can be developed in such a way that process parameters of the method can be determined on the basis of the measured values
- a process parameter can be understood to be any parameter which relates to the casting process, the curing process, the mold control including a temperature control thereof, the cleaning of the mold, a release agent application and subsequent blowing or the evacuation process itself.
- improvements in the process management an optimization of the evacuation can be made such that the vacuum is not too strong, but not too weak.
- the casting quality can be further improved and the cycle times can be further shortened.
- the method may be developed in a preferred embodiment such that the measurement takes place close to the die.
- direct access to environmental parameters within the mold is also possible, and a time delay between air leakage from the mold and measurement can be minimized.
- the method may be developed in a preferred embodiment such that a defined measuring time is determined for the measurement, wherein the measuring time is less than 10 seconds, preferably about one second or less.
- Measuring time can also be a quasi-continuous measurement or a measurement quasi in real time.
- a response time of the probe is preferably less than the selected measurement time.
- the response time of the probe is longer than the selected measurement time, even with an incomplete measurement recording can meaningful result can be obtained if the measuring time is known and the transient response of the sensor or the response delay is mathematically compensated or simulated.
- the process may be in an alternative, but equally preferred
- Embodiment be developed such that the measurement is continuous.
- the transient response of the sensor or the response delay is computationally compensated or simulated. It is possible to measure virtually in real time and to have a good control of the measured values.
- the method can be developed in such a way that a sensor for detecting the measured properties is cleaned between two measuring times, preferably at least once within a casting cycle, the probe preferably being sprayed with a cleaning agent, and more preferably after Spraying with compressed air is blown off.
- a cleaning agent water can be understood alone or in solution with a chemical, wherein the term chemical may include synthetic as well as biological or naturally occurring chemicals.
- the method may be developed in a preferred embodiment such that the suction takes place by connecting to a vacuum source.
- a vacuum source a vacuum reservoir, a vacuum pump or the like can be used. These are well-known, manageable and easily controllable device technology. When using an underground surgeon as a largely passive source, the process is more fail-safe in this regard in view of a sudden pump failure.
- a suction device for suction in the die air, at least one sensor for detecting a moisture extracted air, and a control device for controlling the device comprises.
- the device for implementing the method described above is set up and designed. By the device are in the
- the device can be developed in a preferred embodiment such that the sensor has a response time of less than 1 second.
- the device can be developed in a preferred embodiment such that the sensor is designed for detecting a relative humidity and / or a temperature.
- a combined sensor can also be a
- the device can be developed in such a way that the sensor is arranged in a suction line, preferably near the connection or directly at the connection to the die.
- a largely direct access to environmental parameters within the mold can be achieved by a feeler location which is as close to the form as possible, with the advantages and effects already described.
- the device may be developed in a preferred embodiment such that a protective cap is provided on the sensor, wherein the protective cap is preferably optimized flow. Through such a protective cap can
- Flow effects can be reduced to the measurement.
- turbulence of the suction flow in the suction line which can be caused by the sensor, can be reduced by flow optimization.
- the device can be developed in a preferred embodiment such that the sensor is installed in a housing with a sight glass, so that an effective visual contamination control is possible.
- the housing preferably forms part of a flow path of the extracted air, for example, by being installed directly between a suction connection to the die and a suction line.
- the device may be further developed in a preferred embodiment such that a first suction line and a second suction line are provided, wherein the sensor is preferably provided only in one of the first and second suction line.
- the evacuation can be carried out faster and fail-safe. If the suction line with sensor additionally has a lower suction power, the flow velocities that occur are smaller, and the flow and measurement conditions are rather stationary. This can also lead to a better response of the sensor or to a better numerics in the evaluation of the measured data.
- the suction line with the sensor can be optimized for a reliable measurement, while the suction line can be optimized without the sensor on the evacuation itself, such as the fastest possible evacuation out.
