Definitions

  • the invention relates to an insert for insertion into a mold cavity used in the casting of metals, having a casting cavity, with a body longitudinal cavity extending, a body cavity having body, the body of at least a first molded body having a connection opening through which the Carcass cavity is connectable to the casting cavity, and a second molded body is constructed, which is placed on the first molded body.
  • liquid metal is poured into a mold having a casting cavity.
  • the casting cavity substantially corresponds to the negative shape of the workpiece to be produced.
  • the mold comprises supply lines through which the liquid metal in the Casting cavity can be introduced, as well as cavities, so-called feeders, which serve as a reservoir to compensate for the loss of volume that occurs during the solidification of the metal, and thus counteract a voids formation in the casting.
  • the feeders are connected to the casting or to the vulnerable casting area and are usually arranged above or on the side of the casting cavity. After solidification of the metal remain in the feeder cavities and in the leads still metal residues that must be removed from the workpiece. In this case, it is endeavored to keep the size of these metal residues as low as possible and to design their shape so that these residues can be removed as easily and completely as possible, for example by knocking off.
  • a model plate (or mold) is provided, which corresponds to the inner contour of the casting cavity.
  • a holding device is provided, e.g. a mandrel for fixing the position of the feeder insert or the supply line.
  • a molding material usually molding sand, is applied to the pattern plate in such a way that the feeder insert and the supply lines are enveloped.
  • the molding material is then compacted, so that the feeder and the preformed leads are enclosed by the compacted molding material.
  • Spring arbors typically include a tubular member for mounting on the pattern plate, a spring disposed in the tubular member, and a spring-resting longitudinally telescopically-displaceable mandrel tip member.
  • a feeder sleeve is placed, the lower surface of which is in the starting position, i. before filling the molding material, at a certain distance from the model surface.
  • the feeder insert is moved against the spring force exerted by the spring mandrel in the direction of the model surface, without the bottom of the feeder insert directly into contact with the model surface. Destruction of the feeder insert is therefore prevented even when using high compression forces.
  • a resilient mandrel for holding feeders which consists of a holding and guiding part, a spring and an axially movable jacket.
  • the jacket is cup-shaped and engages spring and holding and guiding part.
  • the spring pins must first be attached to the model plate before inserting the feeder inserts, which is expensive. Furthermore, it is difficult to realize a precisely arranged knock-off edge with a spring pin. This knock-off edge is provided to facilitate separation of the residual feeder, i. of material left in the feeder after casting, to allow casting. The cleaning effort is therefore usually quite high. Spring pins are also quite expensive and susceptible to wear.
  • two-part feeder inserts have been developed in which the two shaped bodies can be displaced relative to one another during the compression of the molding material and thus the forces introduced into the feeder can be dissipated.
  • a feeder insert which comprises at least two along a Lucasrl Kunststoffsachse interlocking mold elements which enclose a cavity for receiving liquid metal.
  • On the first and / or second mold element holding element may be arranged, via which the first mold element carries the second mold element and which are separable or deformable so that a displacement of the two mold elements into each other along the longitudinal axis of the feeder is possible.
  • the feeder insert consists of a feeder volume having a feeder body made of an exothermic and / or insulating material. At its lower, the casting area forming the molding area facing bottom surface a metallic ring member is attached, which forms in itself a trained to form a predetermined breaking point for a forming in the feeder volume feeder remainder.
  • the ring member has a hat-shaped shape with a collar connected to the bottom surface of the feeder body and a lid surface projecting over a rim to the mold surface and having the feeder opening,
  • a feeder with a tube-like body is described.
  • the tube-like body connects the feeder or feeder head directly or indirectly with the casting or the hollow body and contributes to the formation of a breaking edge.
  • JP 9-239489 describes an assembly for making a mold comprising a feeder.
  • a sleeve made of an insulating or exothermic material is pushed over a mandrel which is mounted on a model plate.
  • the sleeve rests on needle-shaped pins which are mounted on the model plate and is thus kept at a distance from the model plate.
  • the gap between the lower end of the sleeve and the model plate is also filled with molding sand.
  • the needle-shaped pins penetrate into the sleeve as it is moved toward the pattern plate, thereby preventing the sleeve from being destroyed.
  • a feeder for use with a mold which has a feeder head and a deformation element, which may be formed according to an embodiment as a bellows.
  • the deformation element can be compressed during the production of a mold during compaction of the molding sand, so that the feeder head moves in the direction of a mold plate and thereby caused by the compaction of the molding sand volume decrease can be compensated. Due to the deformation of the deformation element are in the compaction of the Mold sand caught on the feeder forces, so that the feeder head is not damaged.
  • Various materials are proposed for the production of the deformation element, including steel.
  • the invention has for its object to provide an insert for use in a casting of metals used to have a casting cavity having mold available which absorb the forces occurring during compression of the molding material without destruction or can withstand these and is easy and inexpensive to manufacture , Furthermore, it should be possible, at least in a preferred embodiment of the feeder insert to provide a knock-off edge, which allows the precise separation, for example, of a residual feeder from the casting.
  • the insert according to the invention for insertion into a casting mold having a casting cavity used in the casting of metals comprises a body extending along a body longitudinal axis and having a body cavity.
  • the body initially comprises at least one first molded body, which has a connection opening, through which the body cavity can be connected to the casting cavity.
  • the first shaped body On the side opposite the connection opening, the first shaped body has a second opening.
  • the body further comprises a second mold body which is placed on the side of the second opening on the first mold body or adjacent thereto.
  • the first shaped body is designed as an energy absorption device. In the use according to the invention, therefore, the forces exerted on the insert during compression of the molding material are absorbed by the first molding and the introduced energy destroyed by the fact that the energy absorption causes a deformation of the first molded body.
  • the first molded body has or represents a deformation element.
  • the deformation element forms an integral part of the first molded body.
  • the second molding is supported on the first molding.
  • the second molded body compresses the first molded body together. Therefore, there is preferably a rigid connection between the second and first shaped bodies, so that an efficient introduction of the forces from the second shaped body into the first shaped body is possible.
  • the first shaped body is designed in such a way that it is deformable in its entirety.
  • the forces exerted on the first molded body during compression of the molding material then lead to a compression of the first molded body, whereby the walls of the first molded body are deformed or bent.
  • the first shaped body is configured in such a way that the outer envelope has a substantially tubular or bowl-shaped shape.
  • a tubular shape is understood to mean a cylinder whose cross section can however also be reduced in the direction of the connection opening, so that a tapering section adjoins a cylindrical section.
  • a bowl-shaped shape is understood to mean a shape in which the outer circumference of the first shaped body, starting from the side on which the second shaped body can be placed on the first shaped body, decreases toward the body opening in the direction of the body axis. Depending on the degree with which the outer diameter decreases, the result is a bulbous or funnel-shaped shape. Under a wrapper becomes a Understood surface, which connects the respective outermost points of the first molded body.
  • the second molded body is intended to move substantially only along the body longitudinal axis in the direction of the model plate. It should be prevented in particular that the body longitudinal axis is tilted away from the perpendicular to the model plate and thus the position of the insert or the body cavity in the finished mold can no longer be controlled.
  • the first molded body is therefore designed in such a way that a controlled upsetting is possible.
  • the deformation element is designed as a kind of bellows.
  • the bellows comprises individual segments, which are preferably already arranged inclined to the body longitudinal axis. However, it can also be provided corresponding predetermined bending points, for example, by a lower material thickness at the corresponding points of the first molded body. Particularly preferably, at least two predetermined bending points are provided in each case annularly along the circumference of the first molded body.
  • the bellows comprises individual segments, at the junction of which a kink (or a predetermined kink, see above) is formed.
  • the segments are preferably each inclined at an angle of 0 ° to 80 ° with respect to the body longitudinal axis, preferably 5 ° to 60 °, in particular 15 ° to 50 °. This allows the bellows to be compressed in a controlled manner and evenly.
  • the bellows may be configured, for example tubular or bowl-shaped.
  • the first shaped body has the same diameter at the locations of the creases, so that a tubular envelope results if the creases each define an outer surface.
  • the diameter of the first shaped body at the locations of the creases decreases in each case like a staircase. If the amount of decrease between two creases is always constant, a funnel-shaped envelope results when the kinks are connected by a surface. If the amount by which the diameter at points of the kinks decreases in each case increases, the result is a more bulbous shape of the sheath.
  • the segments are preferably dimensioned in such a way that the expansion of the segments between buckling of the bellows is between 0.1 and 30%, preferably 1 and 20%, of the expansion of the bellows in the direction of the body longitudinal axis, preferably between 1 and 10%.
  • the bellows acting as a deformation element preferably comprises less than 5 stages.
  • One step is formed in each case from two segments, one preferably being arranged parallel to the body axis and one preferably perpendicular to the body axis.
  • the steps can each have the same height or the same extent perpendicular to the body longitudinal axis.
  • the steps of the bellows each have different heights, wherein the arranged closer to the connection opening stages have a greater height than the arranged closer to the second opening stages.
  • the stage located closest to the connection opening has the greatest height of the steps.
  • the height of the steps corresponds to the extent of the segments, which are arranged parallel to the body longitudinal axis.
  • the extension of the segments arranged perpendicularly to the body longitudinal axis increases in an embodiment of the invention from the side of the second opening to the side of the connection opening.
  • the expansion of the bellows in the direction of the body longitudinal axis is in one embodiment of the invention between 20 and 80% of the height of the first molded body or deformation element.
  • the height of the first shaped body corresponds to the maximum extent of the first shaped body in the direction of the body longitudinal axis.
  • the first molded body is formed of an irreversibly deformable material. As a result, energy that is introduced when compressing the first molded body can be absorbed and destroyed.
  • first and second shaped bodies can also be connected to one another, for example by a bond. But it is also possible to form the first and second molded body together as one piece.
  • the properties of the first molded body can be varied within wide ranges, for example, by the wall thickness or the metal or steel grade used.
  • a steel is used whose carbon content is at least 0.12 wt .-%.
  • Steel has a higher melting point compared to cast iron. If the insert according to the invention is used for casting cast iron, the first shaped body made of steel therefore does not melt immediately on contact with the liquid iron. There is first a softening of the steel sheet, followed by a slow dissolution in the inflowing from the feeder insert cast iron. Since steel has a lower carbon content than cast iron, the carbon contained in the cast iron is thinned in the areas of the casting adjoining the first shaped body. This results in an increased tendency to voids formation in these areas. By the measure according to the invention to increase the carbon content of the steel, this dilution effect is reduced and thus the shrinkage formation forced back.
  • the carbon content of the steel is preferably chosen as high as possible. However, in order to ensure sufficient deformability, in particular in the production of the first shaped body, for example by deep drawing, the carbon content is chosen to be less than 0.7% by weight, preferably less than 0.6% by weight.
  • the wall thickness of the first molded body is preferably selected in the steel sheet used in the range of 0.1 to 1.5 mm, particularly preferably 0.2 to 0.8 mm.
  • the first shaped body preferably tapers in the direction of the connection opening. After removing the casting mold, the workpiece then has a constriction at this location. This allows a precise and easy knocking off the metal residues and reduces the cleaning effort considerably.
  • the forces acting on the second shaped body which occur during compression of the molding material, are introduced into the first shaped body and are collected there by deformation of the first shaped body. As a result, damage to the second molded body is avoided.
  • the first molded body for supporting the second molded body has an annular support surface.
  • the insert according to the invention can be attached directly to the model plate by, for example, the connection opening provided on the first shaped body being designed in such a way that a reliable fixation of the insert on the model plate is possible. In order to prevent tilting of the body during the filling and the compression of the molding material, however, it may be useful to provide a centering mandrel on which the insert according to the invention is placed. In one embodiment of the insert according to the invention it can be provided that the second shaped body has a centering recess for receiving a centering mandrel.
  • the erfindunbe insert can be formed in any desired manner and form, for example, in the finished mold a supply line for the liquid metal in the mold cavity.
  • insert is therefore intended to encompass generally any element that can be shaped or deformed onto the casting mold or the model, in particular sleeves, funnel or filter elements, or also feeders and the like.

  • the second molded body 5 is formed of a refractory material and may be insulating or exothermic.
  • the second shaped body 5 is made of the usual materials for feeders, for example, sand, fibers or mineral hollow spheres, which have a suitable binder, such as Water glass, are connected.
  • this material may, for example, also an oxidizable metal, such as aluminum or magnesium, and an oxidizing agent, such as saltpeter be mixed.
  • the wall thickness of the first shaped body 5 is selected in the range which is usual for feeders, so that the optionally desired insulating properties or the required mechanical stability are achieved.
  • the second shaped body 5 can be produced using the methods familiar to the person skilled in the art for the production of feeders.
  • First and second moldings 4, 5 may be connected to one another, for example by gluing, and be obtained as finished feeders. But it is also possible to store the first molded body 4 and second molded body 5 separately and to unite only in the production of the mold.
  • a spring pin 2 is provided to fix the feeder element 3 in its position and secure against tilting. It is not essential to use a spring mandrel for fixing the position of the feeder sleeve 3. For example, it is also sufficient to provide a centering mandrel. This runs essentially along the Suiterl Kunststoffsachse 7, to then pierce the second molded body 5 at the upper wall.
  • a centering opening (not shown) may be provided in the second mold body 5 at the top, through which the centering mandrel can be guided.
  • a spike can be completely dispensed with. However, this increases the risk that the feeder is tilted when filling the molding material and when compressing from the vertical.
