Definitions

  • This disclosure (and claims) relate to a method for producing a mold with a predetermined or predeterminable minimum strength for metal casting.
  • a molding material is entered in a molding box and the molding material is compressed in the molding box.
  • the compression takes place according to the invention in two steps, a first step in which the molding box is moved over a first distance to a stop with a press head and a second step in which the molding material is moved over a second distance into an end position and is thereby further compressed.
  • a length of the second path depends on the nature of the molding material.
  • Molding materials or molding materials that are used in the production of molding materials for metal casting have a higher dimensional stability on the force application side after compression than on the side facing away from the force application.
  • the differences in form strength are proportional to the forces acting on the respective areas. This effect is due to the fact that the forces from the force-introducing side are transmitted at the angle of repose of the molding material to be compressed. This means that the forces are partially supported by lateral boundaries due to friction, for example on a molding box wall or on high or standing model contours.
  • the object of the invention is to produce better molds for metal casting and not to increase the complexity of the production.
  • "Better" can be described in such a way that, even if the quality changes or changes, at least one of several properties of the molding material, it is a mold made of the molding material that is equally hard on the surface.
  • the two-stage method also claimed has a first step and a second step and for the second step there is a second path which is set or changed according to the third feature.
  • a change is necessary when a property of the sand changes. If nothing changes on the sand, no regular intervention is provided. That is the so-called "steady state" of here given controlled system.
  • a measurement of a previous compression process influences the next compression process (or one of the following compression processes).
  • the claimed invention works as a working method completely different from the prior art.
  • Another reference variable is provided, namely the force determined for the quality and hardness of the shape of a previous impression, and adjusts the path for the following impressions, which is given as a second distance before the model plate is lifted.
  • the second distance is set, or the person skilled in the art would say “is set”, when the molding box rests against the top of the press head. Then there is practically no further upward movement for the pressing device working from below . Then the movement takes place, in particular only the model plate is moved further upwards by the pressing device, the mold box itself cannot be moved further, but the model plate is moved a second distance in order to have a target, namely the lower edge of the mold box ,
  • This second distance is set depending on a force.
  • This force is representative of the hardness of the mold on the surface and is used by the invention as a reference variable from which the necessary path in the second impression results. In itself, it is a strength or hardness regulation of the sand surface via a specification of the model stroke as a higher-level regulation. According to the invention, this is not achieved in the same process, but rather after the end of the previous impression.
  • DE 602 17 205 T2 shows a box that requires position control.
  • DE 44 25 334 C2 does not disclose a box, so there is no criterion of the position to be reached relative to the box here.
  • the route guidance therefore has a double aspect, a force has to be achieved, and this force has to be achieved at a time when the model plate reaches the lower edge of the molding box. In addition, this must be carried out with repeat accuracy.
  • the invention requires the path to be changed so that the force (hardness or strength) at the end of the compression is appropriate. If the specialist were to work differently and regulate only one force, the path would not be right if he started from changes in the properties of the under-compressed molding material (molding sand). According to the invention both goals are achieved and as a basis the invention uses the or one of the previous measurements of the force at the end of the associated compression.
  • the invention can thus be viewed from several directions, and it is not obvious from the prior art if the prior art, as the end of its process, also aligns the alignment of the model plate on the lower edge or underside of the molding box. This is imperative for the production of a reasonable or usable form, but how this need is achieved is different according to the invention, and fundamentally different from the way that DE 602 17 205 T2 proposes.
  • the granular, flowable molding material (also molding sand, molding material, later simply referred to as “molding material”), from which the molding material molds for metal casting are made, are generally concrete materials bound to concrete, also called “sand” for short.
  • the molding material is used again and again in a cycle, the starting material being able to be formed over time with, for example, core or green sand (new sand), from the insert core (s) for the cast parts to be produced, and fine material fractions, such as ground sand grains, mixed in a non-deterministic way. This mixture of pure molding material, green sand or used core sand and fine materials changes the properties of the molding material.
  • the molding material can also have a different grain size distribution, which has a direct influence on how much force has to be applied to achieve this Compress molding material to a target value.
  • the molding material properties of a material batch are determined using a standard test. In this test, a standard container is filled with material and compressed with a predetermined force using a stamp. The depth of penetration of the punch into the standard container is measured when the specified force is reached.
  • the measured value that is to say the distance that the stamp penetrates into the standard container, is the value that is set in prior art systems as a constant value for the post-compression of the molding material forms which are produced from the material of the one material batch.
  • the Figure 1 shows the result of several measurements of molding material from a batch of material. It can be clearly seen that with a predetermined force of 3,000N with which the stamp is pressed into the standard container, the depth of penetration of the stamp into the standard container varies between approx. 12 mm and over 50 mm.
  • An invention relates to the method for producing a molding material mold for metal casting with a predeterminable minimum strength of the mold.
  • molding material granular molding material
  • the compression takes place in two steps.
  • the molding box with the filled molding material is moved by a pressing device over a first distance to the stop on a pressing head.
  • the press head is usually arranged above the molding box, so that the molding box is pressed against the press head from below.
  • the press head can have a stamp or multiple stamp, which projects from the press head in the direction of the molding box.
  • the stamp or multiple stamp is held in a predetermined position during the first step and in this position penetrates into the molding material previously filled in the molding box during the first step. Less preferably, the punch or the multi-punch can be actively pressed in the direction of the molding box during the first step.
  • the model plate with the model (in the case of a stationary molding box) is moved by the pressing device over a second distance to an end position for hardening or compaction (creation) of the molding material mold.
  • the second distance is varied depending on the nature of the molding material, in particular for each molding box, preferably automatically set as a function of the composition of the molding material.
  • the new setting of the current compression process preferably results from the measurement of the force of the previous compression process.
  • the method also has the ability to cause the path (the stroke of the punch to be moved) to be adjusted if there is a deviation in at least one property of the molding material. This is the meaning of a regulation that only intervenes if readjustment is necessary, i.e. a system difference has been measured.
  • the regulation thus achieves both, the setting of the force at the end of compaction, which force determines the quality of the shape (its hardness on the surface). And the stroke, which is necessary to reach the lower edge of the molding box, at least essentially with a tolerance of a maximum of ⁇ 5% of the height of the molding box (as the best possible comparison measure).
  • the control is still functional and only has an internal inserted runtime (a dead time in the sense of the control).
  • the strength is measured on the first compressed shape, but is only used as a control variable for the fourth compressed shape.
  • There are two molded boxes between measuring and changing the distance for the upcoming compression box 4 is measured, boxes 3 and 2 in between, box 1 is being compressed and the measurement of box 4 and its molding material form is used for this). Then box 3 is measured and affects box 0, etc.
  • such a dead time has a first approximate effect like a PT1 element, i.e. a delay that does not allow control as directly as an action of the measured value used immediately after the impression (Box 1 on Box 0) and of the control error to the compression process following the measurement, but this type of control is still functional.
  • the punch or multiple punch of the press head can be held or moved as described for the first step.
  • the stamp or the multiple stamp can be pressed into the molding material with increased pressure.
  • the fact that we are talking about a first distance and a second distance means that the molding box is first moved over the first distance, stopped at the end of the first distance and then the model plate is moved for the second distance.
  • the molding box may run through the first path and the second path in a continuous movement.
  • the setting of the second path can take place before the movement of the model plate or the second movement of the pressing device starts and / or while the molding box is moving along the first path.
  • the compression of the molding material by the pressing device and / or the pressing head can be determined or measured in particular by means of at least one sensor or a pressure sensor.
  • the sensor can be arranged in or near a region of the molding material mold that is critical with regard to the dimensional stability.
  • the sensor can, for example, be part of the molding box, in particular integrated into an inner wall of the molding box, so that it directly detects the pressure transferred to the molding material at this point or in this area. In the case of larger cast parts or cast parts with a complicated geometry, several sensors can be present at corresponding critical points.
  • the or one sensor can alternatively be an optical sensor which measures the compression of the molding material in an area within the molding material; for example, a laser sensor whose penetration depth can be adjusted into the material.
  • one or the sensor can be a sound pulse sensor, such as sonar, which uses sound waves to detect a degree of material compression in the molded part or in a region of the molded part.
  • a sound pulse sensor such as sonar, which uses sound waves to detect a degree of material compression in the molded part or in a region of the molded part.
  • the force measured by the pressure sensor and introduced into the molded material part is converted into a signal which is fed to a controller via cable or without cables.
  • the control can be a central control of the molding system, preferably a local control with which the received signals can be processed faster than in the standard controls of the molding systems, some of which are 30 years old.
  • the controller can have a storage medium in which a setpoint or limit values of a setpoint range for the measured applied force are stored.
  • a program stored in the controller for example in a computer, can have an algorithm with which the value received by the sensor can be compared with the target value or the limit values in the storage medium and a possible deviation of the measured actual value from the predetermined target value or target range can be determined ,
  • a correction value can be calculated from this deviation using an algorithm. This correction value can then be converted into a signal and the signal can be sent to an actuator of the molding system which changes the length of the second path, that is to say extends or shortens the second path.
  • the second distance can be adjusted regardless of the size of the deviation by a predetermined distance, for example 0.5mm, 1mm, 1.5mm or any other distance.
  • a predetermined distance for example 0.5mm, 1mm, 1.5mm or any other distance.
  • control can determine the change in the path length as a function of the calculated correction value, that is to say that in this case the control signal specifies a direction of the adjustment movement of the actuator and a measure of the adjustment movement of the actuator.
  • the predefined setpoint or the predefined setpoint range can be a value entered into the control by an operator, or a corrected value which was determined by the control during the creation or production for the mold material form, immediately before the current measurement was produced.
  • the latter means that at the start of the production of the molding material molds, that is, before the start of the compression of the first molding material mold of a production, a setpoint is entered in the control. This setpoint is then compared in the control with the actual measured value of the first molding material form and possibly corrected. The measured actual value or the corrected value calculated by the control then serve the actual value of the second molding material form of the same production as a predetermined target value, etc. In the nth molding material form of the current production, the measured actual value or the by the control calculates the correction value for the n-1st molding material form as a setpoint with which the actual value measurement of the n -th molding material form is compared.
  • the correction value can also be determined from information about the molding material for the molding material mold to be created.
  • the molding material can be scanned when it is filled into the molding box, so that a minimum, average and maximum grain size of the molding material and its volume fraction in the molding material can be determined.
  • a force can then be calculated which is necessary to produce a molding material mold with a predetermined strength.
  • Values such as temperature and humidity can also be included in the calculation if, as described above, the force entered is determined using a sensor.
  • Another invention relates to a molding plant for castable molds made of a granular molding material (molding material), for example betonite-bound molding sand, for metal casting.

  • the molding system further comprises a press head with at least one die, which can comprise a drive decoupled from the drive of the pressing device, and a linearly displaceable lifting cylinder.
  • the press head is arranged in a closing direction of the press device in front of (usually below) the molding box and is not moved by the press device. This means that when the press is closed (the start of compaction) the (filled) molding box, the filling frame, the model plate carrier with the model on top is moved towards the press head. If the filling frame reaches the frame of the press head, the molding box remains stationary. Then the model plate with the model is moved relative to the molding box until it reaches its lower edge. This is a necessary condition, at least this has to be essentially fulfilled.
  • the molding material mold should end at the bottom with the lower edge of the molding box
  • the press head comprises at least one, preferably a plurality of, stamps distributed on the inner surface of the molding box, the at least one molding stamp being fixed in a position relative to the molding box or the molding stamp being actively pressed into the molding material for the mold to be compressed by a drive while the molding box is moved against the press head and / or after the molding box has come into abutment with the press head.
  • the press head preferably comprises more than one form stamp, wherein the plurality of form stamps can form a multiple stamp.
  • the molding system further comprises an actuator coupled to the pressing device or the molding box with a linear drive which is decoupled from a drive of the pressing device.
  • the possible directions of action of the linear drive of the actuator and the drive of the pressing device can be rectified.
  • the fact that the linear drive of the actuator is decoupled from the drive of the pressing device means in particular that the actuator can be moved linearly relative to the pressing device in and against the possible direction of movement of the pressing device.
  • a controller sets a distance (s 1 ) between the pressing device (2) and the molding box via the actuator if the molding box bears against the press head or a frame of the press head.
  • This "if" is not to be read in the sense of a chronological assignment in the claimed molding system. It is the possibility that this setting should be available if the compression is then carried out.
  • the change can also be made from the request on the press head or a frame of the press head, it can also be set at the first stroke, so it has a whole time range, only a structural end, for which it should be set as late as possible to To have an effect.
  • An adjustment path of the actuator can be between 20mm and 100mm, preferably the adjustment path is between 30mm and 90mm, particularly preferably between 40mm and 80mm.
  • the adjustment path depends on the height of the molding box or the size of the filler mold or the cast part to be produced with the mold.
  • the adjustment path can also be larger or smaller than the preferred adjustment path.
  • the adjustment of the actuator changes an overall distance that the pressing device covers when the mold is made from a starting position in which the mold box is not in contact with the pressing head to an end position where the pressing process for the production of the casting mold has ended.

  • the system comprises a controller, the controller being connected at least to the sensor and the actuator in terms of signal technology.
  • the control automatically sets a distance between the pressing device and the molding box or an underside of the molding box. This setting can be started before the press device begins to move and must be completed at the latest shortly before the molding box comes into contact with the press head.

  • Figure 1 shows the standard container already mentioned, which can be filled with a sample of a molding material.
  • the molding material is intended to be compressed in a molding plant into a molding material mold for a metal casting.
  • the molding material can be compressed using a stamp.
  • the stamp is connected to a hydraulic cylinder, for example, which presses the stamp into the standard container with an adjustable force. When the stamp has been pressed into the standard container with the maximum force, the depth of penetration of the stamp into the standard container can be measured.
  • This measurable value is representative of the compression behavior of the material in the standard container and is regarded in the prior art as representative of the compression behavior of an entire batch.
  • the value of the measurement is used to set a distance or a stroke for the post-compression on a press device for producing a molding material. With this setting of the post-compression, an entire batch of the molding material is then processed in a molding plant in the prior art.
  • the graphic representation next to the standard container shows an example of the result of pressing processes with several material samples of a single batch of corresponding molding material with the same force.
  • the force that acts on the stamp is plotted against the depth of penetration of the stamp into the standard container.
  • the measurement results show that the molding material of a batch is not nearly homogeneous, but that when the samples are compressed with an identical force, the depth of penetration of the stamp S into the standard container B is between approximately 12 mm and approximately 50 mm.
  • Figure 2 also shows a graphical representation, as with the Figure 1 has already been arranged.
  • Arrows show plastically that with a fixed stroke (distance), depending on the composition or property of the molding material, the granular molding material is compressed with a force of at least approx. 1700N and at most approx. 2400N. This means that the molds made with these materials under identical pressure have very different strengths, which is disadvantageous for smooth production, for example, can lead to increased rejects.
  • Figure 3 shows in a further graphical representation that the achievable strength of the mold directly (essentially linearly) depends on the force input into the mold at the end of the compression process, or on the force with which the molding material is compressed at the end of the compression process.
  • Figure 4 shows an enlarged section of a graphical representation with a target area for a desired dimensional stability of a molding material mold.
  • the target range is limited by a lower limit value F min and an upper limit value F max . That means a force at the end of the stroke must have been reached so that a curve in a diagram that shows the strength over a distance (from the Figure 2 ), which is within the target range at the end of the stroke.
  • This range can be a hysteresis, or can only have a value as a "switching value" that should be reached or at least slightly exceeded.
  • the Figure 4 can also be seen that an increase in the force or the force input can be achieved by changing the stroke or the distance, which is predetermined by the actuator of the molding system, not shown. Compared to the previously set stroke, the distance (which the stroke covers) has been reduced.
  • the stamp (the press device) therefore covers a different path, however the end of this changed path is still the lower edge of the molding box. But the force at the end of the changed path is different, in such a way that it corresponds to the target value, which is representative of the hardness of the surface (mostly on the surface of the model).

  • the controller changes the distance s 0 , s 1 , s 2 until the model plate 46 reaches the lower edge 40a of the molding box 40. This also (indirectly) changes the stroke of the second section of a twinpress compression. This is due to the differential strength between the setpoint and actual value, which feeds the controller 102.
  • Figures 8a and 8b are self-explanatory in the process. They show the beginning of the second compaction, that is to say the approach of the model carrier 46 to the lower edge of the molding box 40, and the end in FIG Figure 8a In which this lower edge is reached and the resultant force F can thus be seen in the diagram. Another molding material would only have reached the force (and strength) that the curve below shows as having been reached.
  • Figure 9 illustrates the force-displacement characteristics of two "sands" (molded materials). Two curves with not the same force-displacement characteristic illustrate the very different force obtained (dimensional stability) over the same distance s. The same path is marked by arrows of the same length, which result in significantly different forces (shown on the left on the ordinate), approx. 1.5 kN and approx. 2.8 kN (sand A).
  • the path can be adjusted. Exactly this way is the solution with the force control and the change of path in the second compression process (the second stroke), and since the end of the second stroke is mandatory, namely the lower edge 40a of the molding box 40, the stroke to be covered must be changed by the previously described ⁇ s become.
