Definitions

  • the invention relates to a method and a device for slip casting ceramic parts, namely a method according to the preamble of claim 1 and a device according to the preamble of claim 9.
  • the method and the device serve in particular to produce ceramic wash bowls, water closets and the like.
  • the slip is poured into a mold cavity of a pressure-resistant, porous casting mold under a pressure of 0.5 to 2 MPa in such a way that the water contained in the slip is released under the effect of this pressure to the mold parts forming the mold cavity or, if appropriate, through them is led outside.
  • This casting process is continued until the slip in the area of the inner surfaces of the molded parts is dewatered, so that it is deposited on them in a layer of a certain thickness.
  • the casting mold is rotated or inclined and compressed air is fed into the mold cavity in order to push the remaining slip out of the casting mold again via a slip discharge opening.
  • the latter can be formed, for example, by inflatable air pockets which are arranged in the intermediate space and are able to clamp the casting mold by absorbing compressed air.
  • other clamping devices such as hydraulic or pneumatic cylinder units, can also be used instead of inflatable air pockets.
  • a fluid is then introduced into the intermediate space surrounding the mold under a second pressure which is higher than the first pressure.
  • This second pressure acts via a communicating connection on the slip present in the mold cavity, as a result of which water enters the porous molded parts, preferably made of plaster, until a molded product of a certain thickness is formed within the casting mold.
  • the molded parts each have a plurality of channels through which the entering water can be removed from the mold.
  • the moldings also do not have absolutely smooth outer surfaces, it is very often difficult with the device known from DE-C2-37 26 383 and also with other known devices to produce fluid-tight molds. Accordingly, in the known methods, the molded parts are generally clamped with a relatively high pressure acting on the molded parts on all sides in such a way that their service life is considerably shortened.
  • Assembling or garnishing is basically done manually today, i.e. it is carried out by at least one person.
  • the water closets are usually manufactured using the hollow casting process, there is very often a reduction in quality due to a seam that is clearly visible in the end product.
  • a reduction in quality also results from the fact that, in the known processes, the ceramic parts produced and subsequently assembled in separate casting devices cannot usually be produced under the same physical and chemical conditions and can therefore differ in terms of their consistency.
  • the present invention is based on the object of creating a method for slip casting ceramic parts which does not have the disadvantages of the aforementioned methods.
  • the invention further relates to a device used to carry out the method, which is defined by the features of claim 9.
  • the invention in particular also relates to a method for slip casting water closets and the like, which enables the production of a product from at least two interconnectable ceramic parts, and which is at least partly automatically controllable with a relatively high product quality.
  • the device for slip casting ceramic parts shown in FIGS. 1 and 2 and designated as a whole by 1 essentially has a device on a holding device 2 arranged, vertically displaceable bell 3 and three molded parts 4a, 4b and 4c.
  • the latter together with a base part 5 and a further molded part (not shown in the drawing), form a casting mold 6 which stands on a rigid plate 7, preferably made of metal or concrete.
  • FIG. 1 shows the molded parts 4a, 4b, 4c and 5 in a state in which they are detached from one another, while in FIG. 2 the casting mold 6 is shown in an operational state.
  • the molded parts 4a and 4b are horizontally displaceable relative to one another in the direction of arrow 8.
  • the molded part 4c forming the cover of the casting mold 6 can be displaced vertically in the direction of the arrow 9.
  • the molded part 4c can in this case be fastened to the bell 3, for example, with holding means (not shown in FIG. 1).
  • Each of the aforementioned molded parts 4a, 4b and 4c preferably consists of a porous material, for example of polyacrylic resin or another comparable material. These molded parts have a plurality of substantially parallel passages through which the slip water entering the molded parts during operation of the device 1 can be passed. Molded parts that can be used for the device according to the invention are preferably produced by the method disclosed in US Pat. No. 4,591,472.
  • the casting mold 6 and the bell 3 covering it and forming a chamber together with the plate 7 delimit an intermediate space 10 which at least partially surrounds the casting mold 6.
  • this intermediate space 10 several, but preferably five, inflatable air pockets 11 are arranged, which can work together to prevent movement of the mold 6 throughout To clamp the casting process.
  • the air pockets 11 cover the side surfaces of the casting mold 6 almost completely and are connected via air lines 12a to 12e to an air supply line 13 which in turn is connected via an inlet valve 14 to a compressed air source not shown in FIG. 2.
  • This has, for example, at least one compressor and a storage container in order to generate a compressed gas, namely compressed air.
  • the air supply line 13 is also connected to the outside atmosphere via an air outlet valve 15.
  • the compressed air supply line 13 has a controllable shut-off element 16 with which the pressure of the air to be introduced into the air pockets 11 can be regulated. Further likewise controllable valves 17, 18 and 19 are arranged in the line sections 13b and 13c arranged downstream after the distributor cross 13a and in the air line 12e.
  • Each of the drawn molded parts is provided on its respective outer side with an outer layer 20a or 20b or 20c.
  • These outer layers serve, in particular, to absorb and discharge the pressurized water conducted through the passages mentioned above.
  • each outer layer is operationally connected to a flexible hose 21 which is connected to the outside atmosphere via a valve 22.
  • the bottom part 5 of the casting mold 6 has an opening 23 through which the slip can be introduced into the mold cavity 24 of the casting mold 6 and can be removed from it again.
  • the opening 23 is connected to a slip reservoir 27 via a line 26 having a shut-off element 25.
  • the line 26 is - in particular for the slip introduction - additionally connected via a valve 28 and a pump 29 to a slip source, not shown in the drawing.
  • the slip reservoir 27 is communicatively connected to the compressed air line 13 via a compressed air line 30, in which a further shut-off device 31 is arranged, so that the device 1 according to the invention compensates for pressure between the mold cavity 24 and the air pockets 11 can be brought about.
  • the molded part 4c also has an opening 32 opening into the mold cavity 24, which is connected to a line 34 having a shut-off element 33.
  • the latter is - like the line 13 - connected to a compressed air source, not shown.
  • valves or shut-off elements 14 - 19, 22, 25, 28, 31 and 33 shown in FIG. 2 and mentioned above each have a passage and closure means which serve to selectively shut off or release the passage and are provided with at least one for feeding and / or or deriving compressed air serving pneumatic line connected to an electronic monitoring and control device 35, only one such line being drawn in FIG. 2 per valve or shut-off device.
  • the valves or shut-off elements 16 to 19 and 31 can be pneumatically controlled in such a way that the passage cross-sectional areas that can be released by the closure means can be adjusted at least in stages.
  • the electronic monitoring and control device 35 serves to fully or partially automatically control the casting process described below.
  • This control device 35 includes a control circuit with electrical and / or electronic components for measuring, controlling and regulating.
  • the control device 35 can also have operable operating elements with which at least some of the functions controllable by the control device 35 can be carried out manually.
  • the casting process according to the invention is explained in more detail below with reference to FIG. 3.
  • the time t is plotted on the abscissa of FIG. 3 and the pressure P on the ordinate.
  • the solid curve 36 shows the pressure curve that changes during the entire process within the air pockets 11 and the dashed curve 37 shows the corresponding pressure curve within the mold cavity 24. It should also be noted at this point that the pressure values mentioned below are such It must be interpreted that they are each greater than the ambient air pressure by the specified value.
  • the mold parts 4a, 4b and 4c forming the casting mold 6 are displaced in the direction of the arrows 8 and 9 in such a way that the operating state shown in FIG. 2 will be produced.
  • shut-off device 16 and the valves 14, 17, 18 and 19 are then opened and, with a pressure of approximately 100-300 KPa, air is introduced into the air pockets 11 in order to inflate them and to prestress the casting mold 6 formed from the molded parts 4a, 4b and 4c .
  • the slip supply valve 28 is opened and slip is introduced into the reservoir 27 by means of the pump 29 (or by means of compressed air).
  • the shut-off device 16 and the slip supply valve 28 are closed, the valves 31 and 25 are opened and, with compressed air, at least part of the slip previously introduced into the reservoir 27 is passed through the line 26 passed into the mold cavity 24.
  • the valves 22 of the pressure relief hoses 21 are opened, so that the air contained in the mold cavity 24 when filling the slip can at least partially flow out over the porous molded parts 4 and the pressure relief hoses 21.
  • an internal pressure of at most 100 KPa builds up in it. This pressure build-up and the monitoring of the slip level in the casting mold 6 is carried out by the electronic monitoring and control device 35.
  • the shut-off device 31 When the shut-off device 31 is open, it is ensured that the pressure in the air pockets 11 is equal to that which also acts on the free surface of the slip in the reservoir 27. Since this reservoir 27 is in fluid communication with the mold cavity 24, the pressure acting on the slip in the mold cavity 24 is also equal to the pressure which is applied to the slip in the reservoir 27. As a result, the application of almost the same pressure is achieved both on the respective inner surface and on the respective outer surface of each molded part. As can now be seen from FIG.
  • the pressure prevailing in the mold cavity 24 during the casting process is only approximately the same as the pressure acting in the air pockets 11, but is preferably somewhat less than this.
  • This pressure difference is used in particular to ensure that the casting mold is optimally clamped and secured during the entire casting process Keep shape.
  • the pressure difference is built up and regulated by the electronic control device 35, for which purpose the shut-off elements 16 and 31 in particular are regulated differently.
  • the water contained in the slip penetrates through the porous molded parts 4 into the outer layers 20, whereupon the body 38, or the shaped part, of the parts to be produced Wash bowl forms.
  • both the air pockets 11 and the mold cavity 24 are then partially vented. This can be done, for example, by opening the air outlet valve 15.
  • compressed air is again conducted through the line 34 into the mold cavity 24, with the shut-off element 33 open, in order to discharge the slip still present in it via the slip line 26.
  • the residual slip discharged in this way from the casting mold flows, for example, via the shut-off element 25 into the reservoir 27, in which it is kept for further use.
  • the slip can also be discharged via an additional line, not shown, connected to line 26.
  • valves or shut-off devices 14, 15, 16, 31 and 33 are now controlled by the electronic monitoring and control device 35 in such a way that a pressure of approximately 0.3 MPa is obtained both in the mold cavity 24 and in the air pockets remains, the pressure in the air pockets 11 preferably being kept somewhat greater than the pressure in the mold cavity 24.

  • the mold cavity 24 and the air pockets 11 are finally vented together, in accordance with the course of the curves 36 and 37.
  • the mold 6 is then opened and the body 38 is removed, for which purpose compressed air is preferably passed through the hose 21 from the outside, in order to thereby detach the moist body 38 from the inner wall of the mold 6.
  • valves in the line sections 13b and 13c arranged after the distributor cross 13a and in the air line 12e, namely those also provided by the monitoring and control device 35 controllable valves 17, 18 and 19 arranged.

  • the device according to the invention now has the advantage over the device described in the introduction and known from DE-C2-37 26 383 that it is based on a simpler construction.
  • the bell 3 determined to cover the casting mold 6 does not have to be closed in a fluid-tight manner. This is particularly so because the external pressure necessary during the casting process and acting on the casting mold 6 is not built up in the intermediate space 10 but within the air pockets 11 arranged in the intermediate space 10.
  • the device for slip casting a ceramic water closet shown in FIGS. 4 and 5 and designated as a whole by 101 is generally of the same design as the device 1 described above and has a vertically displaceable bell 103 arranged on a holding device 102 and a plurality of horizontally displaceable molded parts , two of which are shown in the drawing and designated 104a and 104b.
