    BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a device for making a castable mark on a core or mold, preferably on a sand core or a sand mold, for casting a molding.
    In order to make series-made foundry products clearly identifiable, a unique labeling is necessary. In order to avoid errors in replacement, an attempt is made to mark the casting part at the earliest possible time in the production process. The target is a direct marking of the molding part during the basic molding.
    It is known from the prior art to place a molding watch in a surface of the mold cavity in a molding which determines the surface of the molding. Such a casting watch is e.g. described in DE 199 58 123 C2. However, such castings are not applicable to molds and cores. In addition, the amount of information for a cast watch is relatively low.
    From DE 199 25 674 B4, it is known to make a code plaque by providing a mold which, prior to casting, is affixed to a mold surface which determines the molding surface. The code plaque is designed to fall apart after the casting is solidified. To identify the molded molding, the casting of the code plaque in the surface of the molding is read by an apparatus. However, this solution has the disadvantage that it is possible to exchange the code posters. Thus, there is no unequivocal uniqueness of the marking of a molding. Furthermore, the solution requires extra work steps, namely the preparation and insertion of the code plate in the mold.
    Another method of making castable markings on a sand core or on a sand mold consists in subsequently incorporating an engraving into the surface of a finished sand core or a finished sand mold that determines the molding surface.
    Oliver Fehr describes in "PTS - Einzelteilnachverfolgung in der Giesse-rei" (Giesserei 94 (2007), booklet 7, pages 78-82) the insertion of a castable engraving into a ready-made sand core using a laser. However, the laser engraving technique can only to a limited extent be integrated into existing automated plants for the production of sand cores or molds.
    Furthermore, it represents an extra work step in the production of the sand core and is thus associated with high costs. The article "Feine Spuren im Sand: Richter-Gravieranlagen descriptions preiswert Sandkerne in Giessereien" describes the insertion of an engraving into the surface of the finished sand core, which determines the casting surface, using special engraving and an automatic engraving system. Also, the preparation of an engraving on the surface of a finished sand core by means of an excavator and an automatic engraving system represents an extra work step and is thus associated with considerable additional costs.
    The prior art analysis shows that known solutions for producing a castable marking on a core or mold, in particular on a sand core or on a sand mold, are either not sufficiently secure as to the uniqueness of the marking of a molding to be casts, or only with high effort, can be integrated into existing automated cores or mold manufacturing plants and are associated with significant additional costs. Furthermore, all of the known solutions for making a castable mark on a core or on a mold are associated with at least one additional work step in the manufacture of a core or a mold.
    SUMMARY OF THE INVENTION It is the object of the invention to provide a device for making a castable mark on a core or on a mold for casting a molding which avoids the aforementioned disadvantages.
    This task is solved by means of a device for making a castable mark on a core or on a mold for casting a molding with the features of claim 1. Claims 2-8 describe advantageous further developments of the device.
    The device according to the invention comprises at least a) several position variable mechanical means which are arranged in a defined location on the mold which depicts the core or on the model, the mold element or the mold box which depicts the mold cavity of the mold. the core or mold is provided with castable convexities or concavities in a surface of the cores or mold which determines the surface of the mold by the molding process, the whole aide aide position variable mechanical means providing convexities or concavities representing a marking code; the direction toward the surface of the core or the surface of the mold is positioned in front of the position variable mechanical means, c) a system for generating and transmitting a setting force for positioning the position variable means, and d) a control system for setting the marking code which is agents except with the system for generating adjusting force.
    Preferably, the position variable mechanical means are configured as bumps which can be moved between at least two positions in a base body. The supports are located in channels formed in the base body, each separately movable, and by means of the system for generating and transmitting an adjusting force, sliding back and forth between the at least two positions in the channels, the extended position presses against the elastically deformable member and bulges it out so that a convexity is formed in the surface of the core or in the surface of the mold cavity which determines the surface of the mold, and in another retracted position does not deform the elastically deformable member.
    Preferably, as inlet openings for the bumps, the resiliently deformable member has blind holes provided corresponding to the channels located in the base body. The supports engage at least in the first advanced position into the channels and press against the bottom of the blind hole, thereby deforming it as previously described, so as to form a convexity in the surface defining the surface of the core or the surface of the mold cavity of the mold. Particularly preferred is the resiliently deformable member and the blind holes of the resiliently deformable member so that the bumps at least partially engage the blind holes in all positions of their forward and reverse movement.
    The bottom of the blind holes may be formed flat, as will the surface of the side facing away from the blind holes of the elastically deformable element which determines the surface of the core or the surface of the mold cavity of the mold, which then remains flat in the non-deformed state. The surface facing away from the blind holes of the elastically deformable member may also be formed convexly vaulted corresponding to a blind hole in the region of one, several or all blind holes, so that in the unformed state of the impact, a concavity is formed in the area of the bottom of each blind hole. in the surface of the resiliently deformable member which determines the surface of the core or the surface of the mold cavity in the mold.
    Between a bump and the bottom of a blind hole, a coupling element may be provided for coupling the bottom of a blind hole to a bump so that it follows any back and forth movement of the bump and correspondingly convexities or concavities are formed in the surface of the elastic. deformable element which determines the surface of the core or the surface of the mold cavity of the mold.
    An impactor may also be positionable in more than two positions of a reciprocating motion, for example in three positions. It may then, in a first, advanced position, press against the elastically deformable member and bulge it out so that it corresponds to the bottom of a blind hole, ie. in the impact region of the impactor, a convexity is formed in the surface of the resiliently deformable member which determines the surface of the core or the surface of a mold cavity of the mold. In a second, retracted position of the impactor, corresponding to the bottom of a blind hole, a concavity is formed in the surface of the resiliently deformable member which determines the surface of the core or surface of the mold cavity of the mold, and in a third position of the impactor the elastically deformable element which determines the surface of the core or the surface of the mold cavity of the mold is flat in the region of action of the mold.
    In order to produce a matrix code as a castable mark, a plurality of position variable mechanical means are arranged in a base body, for example in the form of movable bumpers, which can slide in channels where the whole of the channels or bumpers provided form a matrix. The surface of the device which determines the surface of a core or the surface of a mold cavity in a mold is formed by an elastic member located on the base body which covers the openings of the channels which guide the movable bumpers. Each impactor is individually controllable by means of the system for producing and transmitting an adjusting force and can be positioned in two or more positions depending on the design. By means of the control system, a matrix code consisting of convexities and concavities or planar surface sections is generated, which matrix code causes corresponding positions of the bumps via the system for generating and transmitting an adjusting force. Depending on the position of the bump, a convexity, a concavity or a flat surface section in the surface of the elastically deformable element defining the surface of the core or the surface of the mold cavity of the mold is formed at the site corresponding to the bumper. The entirety of the convexities, concavities, or planar surface sections form the matrix code.
    The insertion of castable markings into a core or mold for casting a molding has the advantage that the device for making these castable markings is not stressed by the casting process and therefore need not be arranged to correspondingly high temperatures.
    In particular, the device according to the invention can be used for the manufacture of a castable marking on a sand core or on a sand mold. However, it can also advantageously be used for the manufacture of a castable mark on a wax core or on a wax mold, as well as in a core or mold for the lost foam method.
    The particular advantage of the device according to the invention consists in the fact that the position variable mechanical means do not come into direct contact with the molding material, e.g. the mold sand of the sand core or the sand mold, with constituents of the molding material binder or, where appropriate, with mold ink. This prevents contamination of the position variable means and, where appropriate, the slides in which they move, with mold material or with components of the mold material binder or, where appropriate, with mold ink.
    The design of the resiliently deformable member substantially determines the convexities caused by the position-variable mechanical means, for example the bumps, in a first, advanced position. These convexities form, by appropriate design, of the elastically deformable member, largely independent of the shape of the bumper as round, well-cast, vaulted convexities. Edges are avoided, which tend to break, especially in sand cores or sand molds. The aforementioned design of the resiliently deformable member relates to the dimensions of the resiliently deformable member, in particular the dimensions bottom of the blind holes and, of course, to the resilient properties of the resiliently deformable member.
    The invention will subsequently be explained in more detail on the basis of an embodiment of a device for making a castable mark on a sand core or on a sand mold. Here are the accompanying drawings in FIG. 1 is a plan view of the surface of a device with a matrix code determining the surface of a sand core or mold cavity in a sand mold; FIG. 2 is a section through a device (schematic); FIG. 3 is a section through another device (schematic); FIG. 4 is a 3D representation of the surface of a device having a matrix code determining the surface of a sand core or mold cavity of a sand mold; and FIG. 5 is a section through another device (schematic).
    FIG. 1 is a plan view of the surface of a device having a matrix code of 6 rows and 6 columns with a total of 36 position-variable mechanical means in the form of bumpers 4, which can move back and forth in channels 2 provided in accordance with the shown matrix in a base body 3, determines the surface 1 of a sand core or mold cavity of a sand mold. Of the reciprocating bumps, 23 are positioned in a first, advanced position, while 13 is positioned in a second, retracted position. FIG. 2 shows a section through the device previously described along section line A-A. Channels 2 are incorporated in a base body 3 in which bumpers 4 are provided for reciprocating and backward movement. The bumpers 4 are in effect connected to a system 5 for producing and transmitting an adjusting force, namely in such a way that each bump can be moved individually. forward and backward and can be positioned in two positions, a first, advanced position 6 and a second, retracted position 7. Opposite the system 5 for generating and transmitting the adjusting force, an elastic deformable member 8 is arranged on the base body 3 for retention and fixation. of the resiliently deformable member 8 engages a circumferential groove 9 in the base body 3. In the resiliently deformable member 8, blind holes 10 corresponding to the channels 2 of the base body 3 are arranged in the surface facing the base body 3 in which the bumps intervene, and this can be felt both in the first, advanced position 6 and in the second, retracted position 7.
    In the first, advanced position 6, a bump 4 presses against the bottom of the blind hole 10, thereby deforming it, so that on the surface 1 of the elastically deformable member 8 opposite the base body 3, a convexity 11.1 forms the second, retracted In position 7, the bumper 4 merely abuts the bottom of the blind hole 10 without deforming the elastically deformable member 8. The surface 1, which faces the base body 3, remains unshaped in the area of operation of the second impacted position 4 in the second retracted position 7, i.e. level.
    Thus, when using the device for producing a castable mark for its purpose, it is placed in a mold for making a sand core or in a model depicting the mold cavity in a sand mold, mold element or sand mold box that the surface 1 of the elastically deformable member 8 forms part of the surface of the mold for producing a sand core or model, mold element or sand mold box which determines the surface of the sand core or mold cavity of the sand mold.
    FIG. 3 is a sectional view of another embodiment of a device for producing a castable mark on a sand core or on a sand mold.
    In this embodiment, the resiliently deformable member 8 of the device is formed considerably wider and for retaining and fixing the adhesive together with the base body 3. The blind holes 10 in the resiliently deformable member 8 are formed similarly deeper.
    FIG. 4 illustrates in a three-dimensional representation the surface 1 of the elastically deformable member 8 with convexities 11. The convexities 11 have a rounded shape. Edges are largely avoided.
    Finally, FIG. 5 is a sectional view of another embodiment of a device for making a castable mark on a sand core or on a sand mold, in which the bumps 4 in this configuration can be positioned in 3 positions. These are a first, advanced position 6, a second, retracted position 7 and an intermediate position 12. The front sides of the supports 4 are each coupled to the bottom of a blind hole with a coupling element 13.
    In this embodiment of the device, the resiliently deformable member 8 is formed such that a concavity is provided in the undeformed state, respectively corresponding to the location of a blind hole 10 or the bottom of a blind hole in the surface 1. If a shock 4 is positioned in the first, advanced position 6, the elastically deformable member 8 is deformed so far in the region of action of this shock 4 or in the region of the blind hole 10 that a convexity 11 is formed in the surface 1. A shock 4 is positioned in the second , retracted position 7, the resiliently deformable member 8 remains deformed in the operating region of this bump or in the region of the blind hole 10, so that a concavity 14 is maintained in the surface 1. If a shocker 4 is positioned in the intermediate position 12, the resiliently deformable member 8 wide in the area of operation thereof 4, or in the region of this blind hole 10, the surface 1 is flat.
