Definitions

  • the present invention relates to a molding for a mold, a mold having at least one molding and a method for molding a green compact.
  • Such a mold is for example from the EP 3 162 521 A1 known.
  • the EP 3 162 521 A1 shows a mold in general form.
  • the casting mold has a first upper molding and a second lower molding.
  • the moldings are inserted between two compacts and brought together by them. Between the moldings, a mold space is formed.
  • the mold parts each have a porous or permeable edge layer on their surface facing the mold space. Air and fluid can be diverted through this surface layer. It is conceivable that the mold has only one molding or more than two moldings.
  • the lower molding of the mold from the EP 3 162 521 A1 has an outlet for discharging water or air. This outlet line is connected to the porous layer.
  • the mold and the moldings from the EP 3 162 521 A1 are relatively large and heavy and thus relatively difficult to handle.
  • the dewatering of the slip, which is filled between the moldings uneven.
  • a molding for a mold is to be made available, which allows a uniform dewatering of the molding.
  • a molded part is to be made available, which allows a simple production of moldings and / or green bodies.
  • a corresponding method is to be made available.
  • An inventive molding for a mold in particular for a multi-part mold, comprises at least one shell for casting a particular ceramic product. At one edge of this molding a flange is arranged for sealing engagement with a sealing surface and in particular for sealing contact with a second molded part.
  • the shell has a first permeability to a fluid and the flange has a second permeability to the fluid. The second permeability is less than the first permeability.
  • the permeability is defined as the volume of a fluid which can be passed through a solid per hour, per square decimeter and per pressure: l / (h * dm 2 * bar).
  • Different permeabilities for the shell and the flange make it possible to specifically control the fluid flow within the molded part.
  • the flange is cast on the shell, in particular made in one piece with the shell.
  • the flange and the shell are thus an integral part of the molding and thus subject to the same loss.
  • the production is facilitated and the molding has no unnecessary joints.
  • the shell and the flange are made substantially of the same material.
  • the material is preferably a plastic, and more preferably PMMA.
  • the production of the same material improves the properties of the molded part.
  • the material properties are the same for the entire molded part.
  • the shell of the molding preferably has a permeability of at least 10 l / (h * dm 2 * bar). Alternatively or additionally, the permeability of the flange is at most 1 l / (h * dm 2 * bar).
  • the molded part may have a seal, which is preferably designed as a circumferential seal. This seal is preferably arranged in or on the flange.
  • a gasket also makes it possible to make the flange with a greater tolerance since the sealing effect can be provided via the gasket and not via the flange.
  • the flange may preferably have a recess in which the seal is inserted. Particularly preferably, the seal is cast in the flange.
  • the recess may have an undercut.
  • the present molding can be constructed in several parts and in particular have an inner and an outer layer.
  • inner layer means that it faces the mold space and thus the subsequent green body.

  • Another aspect of the invention relates to a molded part, in particular a molded part as described herein, wherein in the molding at least one drainage channel is provided.
  • the drainage channel has at least one drainage channel end, via which liquids can be discharged by means of a discharge line.
  • the molded part has a releasable coupling for detachably connecting the drainage channel end to the discharge line.
  • the drainage channel end is formed as a coupling and cooperates with a corresponding coupling with a pressing cylinder.
  • a separate packing for displacing media such as water, is provided which fills the mold, wherein the coupling or the drainage channel end extends through the packing to the Anpresszylinder.
  • the releasable coupling can be arranged in a central region of the molded part and in particular in a region at or adjacent to the center of mass of the molded part.
  • This range is preferably selected such that moments of inertia about an axis of the coupling can be minimized.
  • the releasable coupling is preferably designed such that it can be gripped by a robot.
  • the coupling not only assumes the function of discharging the water but also the function of providing an element for gripping and handling of the molding.
  • the robot grips the mold on a coupling as described herein.
  • the coupling may extend, for example, from the molded part through the filling body, so that when the coupling is gripped by the robot, at least part of the casting mold, such as a filling body, is lifted off together with the molded part.
  • at least part of the casting mold such as a filling body
  • Another aspect of the invention relates to a molding for a mold, in particular a molded part as described herein, wherein the mold part has a shell with a molding surface for molding a particular ceramic product.
  • the shell is at least partially fluid-permeable.
  • In the shell channels are provided, so that the molding surface with a medium and in particular with air and / or water can be acted upon.
  • the molded part has at least one media connection for connecting the channels to a media source and in particular to a compressed air source.
  • channels mean separately formed channels and not the fluid connections within the shell, which are formed by the pores.
  • the channels are typically formed as tubular connections.
  • the air can flow through the pores of the molding surface up to the molded part located in the molding and evenly detached from the molding surface without the molding deformed.
  • the channels are preferably arranged such that each point of the molding surface is spaced from at least one channel which is smaller than 50mm and in particular smaller than 30mm.
  • the molded part surface is the surface facing the mold cavity, i. the surface that is in contact with the mass or slurry during molding of the molding.
  • the channels extend beyond the shell to a lateral flange.
  • the media connection is preferably arranged on the flange.
  • the arrangement of the media termination on the flange facilitates the decoupling of an air supply line, namely the media source.
  • the arrangement of the media outflow on the flange allows a flow through the molded part to the drainage canal end.
  • the channels extend substantially radially from a central region of the shell to the flange.
  • the channels may be arranged such that they do not extend to the molding surface of the shell. That is, the channels are arranged within the molding and have a closed cross-section.
  • the channels are formed as depressions in a surface and the closed cross-section forms only when the molding is arranged in the mold. A closed wall of the channels then results from the mold and the molding.
  • the channels open in the flange in a circumferential collecting channel, which is connected to the media connection.
  • the molded part located in the molding is thereby applied uniformly with compressed air, a uniform detachment of the molding from the molding is thus possible.
  • the molded part has a porous shell and a filler for displacing an unnecessary cavity.
  • the filler and the shell are connected to each other with a detachable connection.

  • the seal 14 is located in a flange 12 of the molding 1a.
  • the molded part 1a also has a shell 11 which is connected to the flange 12.
  • the second mold part 1b is formed corresponding to the first mold part 1a with the difference that the second molded part 1b has no seal. Therefore, only the structure of one of the mold parts 1a or 1b will be explained below.
  • the molded part 1a has a shell 11 and a flange 12, wherein a seal 14 is located in the flange 12.
  • the shell 12 In the shell 12 are drainage channels 15, which are connected to a drainage channel end 151.
  • the drainage channel end 151 is at the same time designed as a coupling 16.
  • a molding 3 Within a mold space between the moldings 1 is a molding 3, which later becomes a green body 31, as soon as the molding is dewatered via the drainage channels 15.
  • the shell 12 is porous and has a molding surface 121 which faces the molding 3.
  • Water can thus diffuse from the molding 3 through the porous shell into the drainage channels 15. It collects in the drainage channels 15 and can then be discharged via the coupling 16. To accelerate this process, a negative pressure can be generated at the coupling 16, that is at the drainage channel end 151.
  • the drainage channels 15 are star-shaped with the center at the coupling 16 is formed (see FIG. 2 ). They open together in a collecting channel 18.
  • the collecting channel 18 is formed as a circumferential annular channel in the flange 12. In the present case, the collecting channel 18 and the drainage channel 15 simultaneously form an air channel 17.
  • a separate media connection ie a separate air supply or air discharge line, on the flange. This can extend through the flange 12 into the annular channel 18. It is also conceivable to provide a separate to the drainage channels 15 media channel network. This may be formed according to the drainage channel network and, for example, each adjacent or in a parallel plane to the drainage channels 15 are located. Media port 171 and drainage channel end 151 may be formed separately.

  • the molded part 1a essentially has a coupling 16 centrally.
  • the drainage channels 15 are arranged in the shell 11 of the molding 1a.
  • These drainage channels 15 extend from the coupling 16 to the flange 12 of the molded part 1 a.
  • the drainage channels 15 are arranged substantially in a star shape, wherein the drainage channels 15, the farther they are from the clutch 16, branch.
  • the maximum distances between the individual drainage channels are limited. That is, an inside of the molding, namely a molding surface 121 (see FIG. 1 ) is spaced from a drainage channel 15 at any point on the surface at most a certain distance (and here 50mm).
  • channels are shown only in about a quarter of the shell. Of course, further drainage channels 15 also extend in the others three quarters of the shell 11.
