Definitions

  • the invention relates to a molded part for the production of molds for foundry purposes by means of a molding material, in particular a core box for the production of cores for foundry purposes, in which limited surface areas, which are exposed to inadmissible wear from the molding material stream when it is introduced, preferably surface areas in which the molding material stream is exposed to high Moved speed and / or changing direction to the mold surface and / or along the mold surface.
  • molded part in the sense of the invention includes both a model and a core box.
  • core in the sense of the present invention comprises parts which are inserted into a casting mold and cavities, undercuts and the like on the finished piece Solve problem areas of mold design, i.e. foundry cores in the conventional sense.
  • the term in the sense of the present invention also includes parts which can be assembled into a complete casting mold and which are produced from the same molding material and according to the same process as foundry cores. Depending on the shape of the casting to be created, both the inner wall and the outer wall of the casting can be limited by the core parts assembled into the casting mold.
  • a molding process is expediently used in which the binder of the core sand is activated not by temperature but by chemical-catalytic processes, so that the molding material hardens in the mold in a short time without an increase in temperature and can then be removed from the mold.
  • cores in the classical sense ie parts produced by the previously known method, which are placed in a sand mold defining the outer contour of the casting
  • cores produced according to the above-described method, which put together the complete casting mold, ie the inner and outer contour of the casting form a defining shape, geometrically very complicated structures that require correspondingly complicated and therefore also expensive core boxes for their production, especially since high demands are placed on the precision of these core boxes.
  • the above-described "cold" molding process with chemical-catalytic curing of the molding material in the core box itself only requires a short residence time of the molding material in the core box, there is a high throughput which can be increased by increasing the filling speed of the molding material stream to be introduced into the core box.
  • the invention is based on the object of designing a molded part of the type described at the outset, in particular a core box, in such a way that an increase in service life with an increase in throughput is possible while maintaining the materials previously used.
  • the wear-prone limited surface areas in particular surface areas for which high dimensional stability is required, are each formed by inserts made of a non-deformable material with high wear resistance, which are embedded in the base material of the molded part.
  • the particular advantage here consists in particular in the fact that the materials customary hitherto can be used to produce such core boxes and that the wall areas to be produced with a material with a higher wear resistance cover only very small area areas compared to the total area. Therefore, the effort required by the more expensive processing of these materials is reduced.
  • those surface areas of the core that come into contact with corresponding counter surfaces of other cores to form a core package retain a high degree of dimensional accuracy over a long service life and thus lead to a noticeable improvement in the quality of the castings produced.
  • the use of inserts advantageously takes advantage of the fact that the surface areas of the molded part which are at risk of wear are defined by delimitable surfaces and thus represent simple mold surfaces.
  • inserts When producing a core box, for example, appropriate recesses can now be incorporated into these defined surface areas, into which a correspondingly shaped insert can then be inserted.
  • Such inserts can be produced with high precision with regard to the mold surface, so that the part of the insert which forms the inner wall of the mold can be produced with dimensional accuracy. This makes a long service life especially for guarantees such surface areas that protrude as projections into the molding material to be introduced.
  • the use of hard metal is provided for the insert pieces. These are hard materials which contain at least one metallic hard material, in particular tungsten, titanium or tantalum carbide.
  • the insert is formed by a pin which projects with its free end into the mold space. Depending on its position within the molding space, such a pin is flowed around to a considerable extent by the molding material that shoots in. If a pin with high wear resistance is used for this purpose according to the invention, which has practically no wear in the service life in question here, there is a guarantee that the recess formed by the pin in the core to be produced has a high degree of dimensional accuracy.
  • the pin can have any cross-sectional shape adapted to the requirements of the core to be produced. In an advantageous embodiment of the invention it is provided that the pin is inserted into a recess in the base material of the molded part.
  • the insert piece made of wear-resistant material is made cup-shaped in the base material.
  • the compressing molding material stream flowing into the bowl under deflection cannot change its dimensions over a long operating time because of the high wear resistance of the feed material.
  • the protrusion formed on the core produced and serving as the core brand also has high dimensional accuracy.
  • the core parts can be assembled with dimensional accuracy, so that the castings produced therewith do not have any burrs even after a long operating time of the core shapes and thus a high shape quality of the casting can be achieved.
  • the elaborate plastering of cast burrs is thus eliminated.
  • With a corresponding conical design of the core marks, which are assigned to one another and formed from the projection and recess, a reliable frictional connection of the two core parts is also possible.
  • the cup-shaped insert is designed in its bottom area as a gas outlet nozzle which is connected to the outside of the molded part via at least one outlet channel.
  • the gas outlet nozzle is formed by a releasable base piece which has a mushroom-shaped head, the upper head surface is closed and the edge of which runs parallel and at a distance from the cross-sectional contour of the cup-shaped insert and that the space under the head with the Exhaust duct communicates.
  • An outlet nozzle designed in this way has a considerable outlet cross section, so that only a width of, for example, 0.2 mm needs to be provided for the gap between the edge of the head and the wall of the cup-shaped insert, in order firstly to let the gas quantities to be let out in the shortest possible time and to prevent the smallest grain fraction of the molding material from passing through.
  • the base piece is mounted axially displaceably in the molded part and is connected to a sliding drive.
  • the base piece also takes over the function of the ejector, so that a separate element can be omitted here and the manufacture of the mold is thus simplified.
  • Another advantage of this embodiment is that the gas outlet nozzles are cleaned in this area with each working stroke. Since both the insert piece connected to the molded part and the base piece are made of wear-resistant material, there is no disadvantageous influence on the dimensional accuracy of the core produced.
  • At least the surface area of the core box opposite an insertion channel consists of an insert made of a material with higher wear resistance than the material of the core box itself.
  • the highest wear stress occurs in this area of the core box, because this area when shooting in is practically loaded by the entire amount of molding material to be introduced into the core box and, moreover, the molding material in this area has the highest kinetic energy.
  • the position of the entry channel with respect to the mold interior can be freely selected within certain limits, there is also the possibility of arranging the entry channel at a location in the core box at which the area of the inside wall of the mold opposite the entry channel is geometrically simple and therefore easy to generating surface contour.
  • a bullet channel 4 is arranged in the upper box part 2 and is connected to the molding material supply of the core molding machine.
  • the bullet channel 4 is formed by a tubular body 5 made of a wear-resistant material which is embedded in the material of the core box upper part 2.
  • an insert 7 made of a wear-resistant material is also inserted into the core box wall on the side opposite the mouth 6 of the entry channel 4, the surface 8 of the insert 7 facing the mouth 6 corresponding in shape to the shape of the core part to be produced.
  • additional insert pieces can be arranged in the form of a pin 10 protruding into the mold space, through the core to be produced or the one to be produced Mold indentations, for example core marks can be molded.
  • the pin 10 is inserted in a recess in the base material of the lower box part 3 and its height can be adjusted precisely by means of a backing 11.
  • the stream of molding material enters the interior of the mold at high speed and hits the surface 8 of the insert 7, is deflected there, so that the interior of the mold progressively fills completely with molding material. In this process, almost the entire amount of molding material filling the mold interior strikes the surface 8 of the insert 7.
  • the molding material 10 also flows around the pins 10. Since the risk of wear essentially only exists on the pin 10 and in the area directly opposite the mouth 6, the surface area of the inner mold wall covered by the insert 7 need only be slightly larger than the projection of the entry opening 6 onto this part of the inner mold wall.
  • one part or one core side has depressions such as are molded into the molding material with the aid of the pins 10 shown and described in FIG. 1.
  • the other part or the other core side must have correspondingly assigned pin-shaped projections, which appear in the molding box as a depression. Since the molding material flows into such depressions with deflection and has to be compressed into the depressions, on the other hand, when the peg-shaped projection formed by the depression is moved with its surface relative to the shaping surface of the depression in the box part, this area is also exposed to high wear .
  • the box parts here the box lower part 3 'are provided with a cup-shaped insert 12 made of wear-resistant material in this area, so that the dimensional accuracy of the cone-shaped projection to be molded is guaranteed over longer operating times. Since both the depression to be molded with the molding box according to FIG. 1 and the peg-shaped projection to be molded with the molding box according to FIG. 2 retain their dimensional stability unchanged even in the case of large quantities, the two core or molded parts to be produced can be inserted into one another accurately and without play, so that there is no offset between the two core or molded parts in the parting plane. The castings thus produced have practically no burr.
  • the cup-shaped insert 12 in Fig. 2 is now designed so that it also forms a gas outlet nozzle. Accordingly, the insert 12 is divided into a tubular wall part 13 and a detachable base piece 14, which is a mushroom-shaped Head 15 has.
  • the tubular wall part 13 has a shape cross section which does not have to be circular, but is shaped arbitrarily according to the requirements of the core to be manufactured or the associated core brand of the other part.
  • the outer contour of the mushroom-shaped head 15 is dimensioned accordingly, the edge 16 of the head 15 facing the inner wall of the tubular part 13 running parallel and at a short distance from the inner wall 17.
  • the width of the gap thus formed is, for example, only 0.2 mm.
  • the space under the mushroom-shaped head communicates with a gas outlet 18, so that when the molding material is shot in, the gas can escape from the interior of the mold through the cup-shaped inserts 12 forming the gas outlet nozzles. This ensures that the peg-shaped projections to be formed on the core or molded part to be formed are fully formed and fully compressed.
  • molded parts generally have a large number of gas outlet nozzles, but also a large number of core brands, the shape of the gas outlet nozzles described above also offers the possibility of simultaneously using them as ejectors.
  • a shaft 19 connected to the base piece 14 is connected to a drive device 20. After the core box has been opened, the base pieces are moved in the direction of the mold interior via the drive 20 and the finished core can thus be detached from the mold and then removed.
  • the use of the base piece 14 of the cup-shaped inserts 12 as ejectors is not limited to the exemplary embodiment shown.
  • the special design of these outlet nozzles consists of a tubular part made of wear-resistant material and a base piece also made of wear-resistant material. This makes it possible to use such gas outlet nozzles as ejectors in which the top surface of the base piece lies in one plane with the adjacent surfaces of the mold inner wall. This has the advantage that the gas outlet nozzle cleans itself by the ejection process, but on the other hand it is ensured by the use of wear-resistant materials that molded material wedges wedged in the gap between the head piece and the wall of the insert piece practically do not lead to wear and thus to an expansion of the gas outlet gap to lead.
  • FIG. 3 shows the design of such a gas outlet nozzle which can be actuated as an ejector on a larger scale.
  • the shaft 19 connected to the head 15 has a stem-shaped design and has three or four wing-like projections 21, over which the base piece is guided in a centered manner, so that a constant gap width between the edge 16 and the inner wall 17 is ensured is.
  • the inserts 5, 7, 10, 12 and also the bullet channel 4 are made of a non-deformable, wear-resistant material. Hard metals are preferably used for this purpose. The composition also depends on the wear and tear. The bullet channel 4 is subject to the highest stress.
