Definitions

  • the invention relates to a slip die casting mold with the generic features according to claim 1 and to a slip die casting system and a die casting method using such a slip die casting mold.
  • a slip die-casting mold for the production of, in particular, sanitary articles, for example wash basins or toilet bowls, are generally known.
  • a slip die-casting mold is composed of several molded parts. The molded parts are placed under high pressure from the outside and firmly clamped against each other. Subsequently, slip is poured into a molding space, which is formed in an area between the molded parts. The pressure of the slip is several bars. Liquid penetrates from the slip into the walls of the molded parts and through them out of the die. The solids of the slip deposit on the inside of the walls of the molded parts and form a body. After die casting, the molded parts are moved apart again in order to expose the cullet as the cast part.
  • a slip die-casting system has press rams which are clamped against the molded parts from the outside.
  • press punches are adjustable alone or together with molded parts mounted thereon along so-called press axes in only a linear direction.
  • press axes in only a linear direction.
  • Die casting molds which are intended for the die casting of cast parts are not usable if the cast parts are to have free spaces which are undercut from the perspective of mutually adjacent and right-angled linear press axes.
  • two cast parts are usually cast separately from one another, in order then to glue the two pieces together before the pieces that are glued together are sintered.
  • JP H03 83609 A relates to an arrangement for a slip casting process.
  • molded parts are fixed to each other with a magnet. Another molded part is inserted into a cavity that is created. However, the other molded part is not freely in the mold.
  • the other molded part is temporarily fixed to an assembly device with negative pressure. After opening the mold by removing a first molded part on the underside, the further molded part hangs from the cast piece and is only then coupled to the assembly device.
  • DE 10 2006 019 915 A1 relates to a slip mold with two mold parts, which together form a casting space for casting a ceramic casting, an insert molding for forming an undercut wall of the casting in a demolding direction of the first molding and an adjustment device with a pivoting mechanism for pivoting the insert part within the casting space between an undercut casting position and a non-undercut demolding position.
  • An articulated connecting element of the pivoting mechanism leads through a passage opening which is formed in one of the molded parts.
  • DE 199 55 629 A1 relates to a method and a device for casting sanitary articles with a central molded part rotatable about a central axis perpendicular to the clamping direction of the casting mold, which has two first molded parts which can be pulled off the central molded part on two opposite sides and which are parallel to the central axis, wherein in these opposite sides of the central molded part each have a mold for a pre-cast part of the sanitary article and an inner core anchored in the central molded part, the inner cores protruding perpendicularly to the central axis from the central molded part into the first or second lateral molded part and being displaceable parallel to the central axis.
  • EP 1 088 634 A2 relates to a casting mold for molding sanitary articles, comprising two profiled parts which are connected to one another to form a mold space to be filled with slip and which are detached from one another for demolding.
  • An insert for forming an undercut area is attached to one of the parts of the mold in the mold space with a carrier unit. The insert can be adjusted with the carrier unit between a first casting position for molding the undercut area and a demolding position in which the insert is removed from the undercut area in the lateral direction.
  • the object of the invention is to further develop a slip die casting mold, a slip die casting system or a die casting method using such a slip die casting mold in such a way that undercut cast parts can also be produced in one casting process.
  • slip die casting mold with the features according to claim 1, by the slip die casting system with the features of claim 9 or by the die casting method with the features according to claim 14.
  • Advantageous refinements are the subject of dependent claims. Accordingly, a slip die casting mold with a mold space for die casting a cast part and with mold parts enclosing the mold space in a die casting position is preferred, a first of the mold parts being adjustable in a first direction.
  • an additional molded part is arranged in the die-casting position between a section of the first molded part facing the mold space and the molded space, the additional molded part being at least during a first demolding step in a demolding direction with both a directional component in Directional component is adjustable in a second direction perpendicular to the first direction.
  • the proportions of the at least two directional components of the demolding direction are understood in the sense that none of the proportions is equal to zero, so that the demolding direction runs obliquely to the first direction, in particular both portions between 5 ° and 85 °, in particular between 10 ° and 80 ° run diagonally to the first direction.
  • a slip die casting mold is understood in particular to mean a die casting mold in which slip is pressed into the mold space under a pressure of several bars, in particular under a pressure of more than 5 bar, preferably under a pressure of 10 to 20 bar.
  • the molded parts are made of a permeable material so that liquid penetrates into the molded parts from the slip. Solid components of the slip form a body on a wall of the molding space.
  • the slip material is preferably ceramic material in order to cast, in particular, sanitary articles such as wash basins, bidets or toilet bowls as castings.
  • at least one of the molded parts also has an outlet opening in order to be able to discharge the liquid of the slip from the die casting mold in a targeted manner to the outside.
  • two or more molded parts are provided in such a die, which are moved towards each other in a linear direction to enclose the mold space, or are moved away from each other in a linear direction to open the mold space to remove a body formed therein.
  • at least one additional molded part which is permeable to the liquid components of the slip is provided, which is a further molded part between the other molded parts is used.
  • the additional molded part has at least one wall, which also forms the molding space.
  • the additional molded part has in particular no wall, which forms a particularly liquid-tight outer wall of the die, as is the case with the other molded parts.
  • the additional molded part is arranged within the die or between the other molded parts in such a way that it is adjustable in an oblique direction from the point of view of the linear directions of movement of the other molded parts, in particular the molded parts adjacent to the additional molded part. This enables the molded part with its permeable body to be inserted between the other molded parts. In this way, undercut walls of a cast part can also be cast.
  • the first molded part can only be adjusted along the first direction and the additional molded part can only be adjusted in the demolding direction at least during the first demolding step.
  • the advantageous movement in the demolding direction which can be carried out at least initially by the additional molded part, is emphasized again.
  • the additional molded part can optionally also be adjusted in other directions.
  • This demolding direction is oblique to the adjustment direction of the first molded part, which is arranged adjacent to the additional molded part in the assembled state.
  • a part of the molding space is formed, in particular at least in sections, between the first molding and the additional molding.
  • this part of the molding space can be inclined to the demolding direction of the first molding run so that an undercut portion of the casting is formed during casting.
  • the additional molded part and the first molded part are designed to enclose a part of the molding space at a distance from one another in the casting position in such a way that the part of the molding space for forming a part which runs both obliquely to the first direction and obliquely to the second direction Molding section runs.
  • the advantageous embodiment is emphasized with two adjustment directions, in particular perpendicular to one another, for two of the molded parts, between which the additional molded part is inserted in the casting position or between which the demolding direction thereof extends.
  • the demolding direction of the additional molded part extends obliquely to both demolding or adjustment directions of the adjacent molded parts in an angular range between these two directions.
  • the additional molded part has a molded part holding device which extends laterally transversely to the first direction up to an outer circumference of the first molded part or further than an outer circumference of the first molded part or a molded part covering of the first molded part.
  • a molded part holding device can be, for example, a metal carrier which is fastened to the additional molded part or leads into it. Starting from the additional molded part, the metal carrier or the molded part holding device leads away from it and, in the assembled state, leads between two adjacent walls of adjacent molded parts to at least one outer wall of these adjacent molded parts.
  • a recess can be formed in one or both of the molded parts in a wall facing the other molded part, which is adapted to the contour of the holding device, so that the two molded parts abutting against one another in the assembled state firmly hold the holding device between them.
  • this is not absolutely necessary, since a loose guide with play for the holding device between the assembled molded parts may be advantageous if, for example, undesired tensions between them would otherwise occur during the pressing of the molded parts.
  • an embodiment is also advantageous in which the additional molded part has a contour that widens in the demolding direction.
  • a wedge-shaped configuration of the additional molded part can thus be provided in order to form wedge-shaped walls of the cast part which, in particular, form undercut walls of the cast part in two adjustment or removal directions of the molded parts adjacent to the additional molded part.
  • any other shaped parts can be used, which in particular also have structured, shaped walls.
  • the criterion is in particular that, in the completely closed form of the die, those walls of the additional molded part have no walls which project with respect to the direction of their demoulding, which would enable corresponding recessed walls of the cast part.
  • the use of a plurality of additional molded parts, which may also be nested in one another, could possibly be implemented.
  • a slip die-casting system with such a die and with a receptacle for at least this die and with a holding and adjusting device for temporarily holding the additional molded part and for adjusting the additional molded part in a demolding step in a demolding direction is also independently solving the problem both a directional component in a first direction and additionally a directional component in a second direction perpendicular to the first direction.
  • Such a receptacle for such a die is essentially known per se and is used for clamping or fastening the individual molded parts of such a die, so that the molded parts can be moved towards and away from one another.
  • the receptacle is used to put the individual molded parts under an external tension during the die casting by means of the receptacle components themselves or by means of a press ram attached to it, which counteracts the pressure of the cast slip and holds the molded parts firmly together.
  • a special feature is the holding and adjusting device, which can hold the additional molded part in a defined position during assembly, disassembly and the die casting process.
  • the holding and adjusting device is designed to adjust the additional molded part in a respectively required position and, if necessary, spatial position. This makes it possible to place the additional molded part in a predefined position within the receptacle by means of the holding and adjusting device before the further molded parts are moved towards the additional molded part in order to finally enclose it firmly and to accommodate it between them.
  • the holding and adjusting device in the closed position can also serve the additional molded part preload against one or two adjacent molded parts, so as to form the mold space and prevent the additional molded part from moving into a section in which a wall of the cast part is to be formed.
  • the holding and adjusting device can also decouple or free the additional molded part according to an alternative embodiment and act as an inactive holding arm in order not to undesirably counteract the pressing forces which are exerted on the adjacent molded parts from the outside by pressing cylinders act.
  • the holding and adjusting device e.g. a coupling mechanism, which allows an adjustment of the additional molded part due to forces acting through adjacent molded parts without being undesirably prevented by the holding and adjusting device.
  • the holding and adjusting device serves in particular to hold the additional molded part on the cast cast part, while at least one of the molded parts adjacent to the additional molded part is moved away.
  • the additional molded part can subsequently be guided away from the cast part by means of the holding and adjusting device in its demolding direction.
  • the additional molded part can be removed or removed from the cast part at an earlier point in time while the adjacent molded parts have not yet been completely moved away. It is also possible to guide a holding device for the cast part under the cast part before removing the additional molded part from the cast casting or cullet, so that the additional molded part is only removed when the cast part is in one adjacent section is held and supported by the holding device. This prevents bending or shearing of adjacent walls of the casting.
  • an embodiment is advantageous in which the holding and adjusting device has a drive for the automated adjustment of the additional molded part.
  • a drive can in particular be an electric motor drive which has an adjusting element which grips or is attached to the molded part holding device and which can hold and / or adjust the molded part holding device with the additional molded part arranged thereon.
  • any other drive types can also be used, in particular hydraulic and pneumatic drives.
  • the holding and adjusting device has a mechanism for manually adjusting the additional molded part.
  • grip elements can be provided, which can be gripped by a technician in order to manually bring the auxiliary molded part into a different position or to adjust it.
  • a design is also feasible in which the receptacle holds or guides the first molded part for demolding with the first direction in a downward direction, in particular vertically downward from the molding space.
  • Such a procedure can be used particularly advantageously when casting toilet bowls, in which the first molded part is inserted into the actual bowl opening and is preferably removed downwards, the additional molded part then being able to be arranged around a rear wall of the toilet bowl, which is not runs vertically downwards or vertically upwards when in use, but leads diagonally to the rear wall behind the toilet.
  • the task is solved independently by a die casting method with such a die or in such a die casting system with, after casting a casting, the steps of removing the first molded part in a first direction away from a mold space, at least initially holding an additional molded part in the mold space and thereafter Removing the additional molded part in a demolding direction with both a directional component in the first direction and additionally a directional component in a second direction perpendicular to the first direction.
