Definitions

  • the present invention relates to a feeder insert for insertion into a casting mold used in the casting of metals, comprising a feeder body consisting of an insulating and/or exothermic feeder material, the feeder body having a peripheral and outwardly directed outer contour side wall, a side wall delimited at least by the side wall Feeder cavity for receiving liquid metal and a feeder port for connecting the feeder cavity to a mold cavity of the mold during the casting process.
  • the feeder opening is generally formed in a base area of the feeder body, with the feeder cavity being delimited by a cover area on the side opposite the base area, with a further opening being able to be formed in the cover area.
  • the feeder inserts In foundry technology, it is often necessary to arrange additional feeder inserts in the casting molds, the feeder body of which fills with the liquid metal when the casting is poured and compensates for volume deficits that occur during the solidification of the casting in order to prevent the formation of cavities in the casting.
  • the feeder inserts must be designed in such a way that the liquid metal fed into them solidifies later than the casting, so that material can be transported to the casting during the solidification process, which tightly feeds the casting.
  • the modulus of the feeder sleeve must be greater than the modulus of the respective nodal point of the casting to be cast.
  • the feeder inserts have the feeder cavity delimited by the feeder body for receiving liquid metal and a feeder opening for connecting the feeder cavity to the mold cavity of the casting mold during the casting process.
  • the feeder cavity consists of an exothermic and/or insulating feeder material.
  • the exothermic material should include an oxidizable metal and an oxidizing agent, which can produce an exothermic reaction, it also being proposed to add components of an insulating refractory material to the material mixture, resulting in an exothermic-insulating material mixture.
  • the heat balance of pure insulating risers is poorer due to the lack of active heat supply during the solidification process.
  • feeder bodies made from exothermic/insulating granular feeder material are also known.
  • a dimensionally stable, metallic feeder is, for example, in EP 1 864 729 A2 described. Since no exothermic reaction takes place with these feeder inserts, only the insulating effect is taken into account. Since the dimensionally stable metal body must not melt, it requires an appropriate wall that withdraws the heat from the liquid metal when it comes into contact with it, which can lead to the formation of edge shells on the metal rest of the feeder. In addition, gases produced during the casting process cannot be discharged and so-called gas defects or gas explosions can occur inside the feeder.
  • EP 2 489 449 B1 known to enclose a feeder body made of exothermic feeder material with a shell made of insulating refractory material.
  • a shell made of refractory material is relatively expensive.
  • a feeder insert with an exothermic feeder body in which the side wall of the feeder body, starting from the upper wall part, extends convexly outwards and merges at the lower end into a passage part, also known as the feeder neck, with the side wall having several frames protruding into the interior, which the ends merge into the upper wall or the passage part.
  • the feeder body can either be composed of several separately manufactured parts or be manufactured in one piece using a lost core. However, the use of a lost core in production is expensive.
  • the object is achieved in particular by a feeder insert with the features mentioned at the outset, the feeder insert comprising a sleeve made of sheet metal in addition to the feeder body, the sleeve surrounding the outer contour at least in sections and at least one cavity being formed between the sleeve and the outer contour.
  • the invention therefore provides that the feeder body made of a granular and/or fibrous feeder material is surrounded by a casing at least along a longitudinal section in the circumferential direction, with an air gap between at least a section of the inside of the casing and a section of the outer contour filled cavity is formed.
  • the feeder insert thus has insulation formed by the at least one cavity, which reduces the amount of heat during the casting process that is emitted from the feeder body to the molding material surrounding the feeder insert. If the feeder sleeve is appropriately dimensioned, it has either a higher modulus than conventional feeder sleeves (without casing) with the same weight or the same volume of the feeder body, or the same modulus with a lower weight or smaller volume of the feeder body.
  • the cavity it is not absolutely necessary for the cavity to also be delimited by the sleeve in the axial longitudinal direction of the feeder body. Rather, the at least one cavity can be closed by the feeder body itself, for example at its upper end facing the cover area. It is preferred that the at least one cavity is delimited by the shell on one side in the axial longitudinal direction, in particular in the direction of the bottom region.
  • the sleeve can in particular be pot-shaped, with the sleeve having at least one base section, which may have an opening and which bears against an end face, in particular of the base area of the feeder body.
  • the sleeve and the feeder body are therefore two different components of the feeder insert.
  • the shell is formed from a metal sheet, in which case the shell can in particular have a wall thickness of at most 2 mm [millimeters], particularly preferably of at most 1 mm.
  • the casing which consists of sheet metal, is produced in a deep-drawing process.
  • the casing can be connected to the feeder body, in particular in the base area and/or cover area, in particular in a materially bonded manner, for example by means of an adhesive, or in a non-positive manner.
  • a large number (at least three, preferably at least five or more) be provided by spacers, which counteract a radial deformation of the shell in the direction of the outer contour of the feeder body.
  • spacers can be arranged and fastened as independent components between the inside of the sleeve and the outer contour of the feeder body.
  • the spacers are formed in one piece with the casing or with the feeder body.
  • the outer contour of the feeder body can have a multiplicity of outer contour projections against which the inside of the sleeve rests.
  • the sleeve which is made of sheet metal, for example, can have, for example, embossing, beads, projections or the like as spacers.
  • the casing could be designed in a wavy or zigzag shape, for example, with the corresponding low points being able to bear against the outer contour of the feeder body as spacers.
  • the spacers are distributed regularly over the outer contour of the feeder body.
  • the spacers are point-shaped, a single coherent cavity can be formed between the casing and the outer contour of the feeder body. However, it is also possible for the spacers to extend over the length or over the entire circumference of the outer contour, so that a plurality of cavities which are separate from one another are formed.
  • the sleeve surrounding the feeder body radially on the outside in the circumferential direction preferably extends from the bottom area over at least half the length of the feeder body.
  • the sleeve surrounding the feeder body in the circumferential direction preferably extends over two thirds of the length of the feeder body or even over the entire length of the feeder body. Preferred lies the sleeve-shaped or cup-shaped casing with its inner surface at the radially outermost points of all outer contour projections of the feeder body.
  • the sleeve has a base section which extends over the end face of the feeder body in the base area of the feeder body and in particular is in contact with the base area of the feeder body at least in sections, the sleeve having an opening in the base section that is assigned to the feeder opening of the feeder body , where the opening of the shell is smaller than the feeder opening.
  • a (metallic) breaker core is simultaneously made available through the shell, which constricts the connection between the feeder opening and the casting and thus specifies a predetermined breaking point for the metallic feeder residue located in the feeder cavity after the casting process.
  • the sleeve can be designed in its bottom section in such a way that, starting from the feeder opening of the feeder body, it tapers towards its opening facing the casting.
  • the shell of the shell surrounding the feeder body in the circumferential direction and the base section of the shell forming the breaker core can thus be produced in one piece.
  • the sleeve can thus be attached to the feeder body, which is in particular a one-piece part, in a second process step after it has been produced.
  • the outer contour preferably has a large number (at least three, preferably at least five or particularly preferably at least ten) of outer contour projections and/or outer contour recesses. When the outer contour projections are formed, the inside of the casing rests against the outer contour projections.
  • the feeder body With a corresponding dimensioning of the feeder body, it has a higher modulus in comparison to conventional feeder bodies (without projections and recesses on the outside) with the same weight or the same volume of the feeder body.
  • the outer contour projections also serve as support points/surfaces for the cover.
  • the feeder body is made in particular from granular and/or fibrous feeder material and preferably made from exothermic material, ie it comprises at least one oxidizable material, for example an oxidizable metal, an oxidizing agent, optionally fillers and/or fibers and a binder.
  • oxidizable material for example an oxidizable metal, an oxidizing agent, optionally fillers and/or fibers and a binder.
  • the outer contour projections and/or outer contour recesses can have any shape.
  • the outer contour projections/outer contour recesses can be designed in the shape of a cube, cuboid, dome-shaped, pyramid-shaped or with a trapezoidal section, in which case the edges can be rounded.
  • the outwardly directed surface of the outer contour projection can be curved in the circumferential direction corresponding to the radius of the feeder body at the appropriate point.
  • the outer contour projections and/or the outer contour recesses have a height or a depth which is in particular at least 5%, preferably at least 10% and at most 45%, preferably at most 20% of the maximum outside diameter of the feeder body.
  • the outer contour projections and/or outer contour recesses preferably extend longitudinally in one direction and in particular along a longitudinal axis defined by the feeder opening of the feeder body.
  • the elongated outer contour projections/outer contour recesses extend, in particular, starting from the base area or the cover area.
  • the cross-sectional design of the elongated outer contour projections and/or outer contour recesses can be arbitrary, but is preferably rectangular or triangular, optionally with rounded edges.
  • the outwardly directed surface of the elongated outer contour projection is also curved in the circumferential direction corresponding to the radius of the feeder body at the appropriate point.
  • the outer contour projections and/or outer contour recesses each extend along the entire side wall of the feeder body.
  • the elongate outer contour projections and/or outer contour recesses are preferably arranged uniformly one behind the other in the circumferential direction, it being possible for a total of at most 9, preferably at most 6, outer contour projections and/or outer contour recesses to be provided.
  • the outer contour of the feeder body has a lamellar shape.
  • a corresponding core box for the production of a feeder body can thus have elongated recesses/protrusions corresponding to the outer contour projections and/or outer contour recesses on its inner surface defining the outer contour.
  • a width of the outer contour projections and/or the outer contour recesses and/or a distance between adjacent outer contour projections/outer contour recesses changes along their length, in particular along the longitudinal axis of the feeder body.
  • the outer contour projections extending along the longitudinal axis of the feeder body are in particular designed such that they are arranged directly adjacent to one another in the circumferential direction of the feeder body, with the feet of the projections (in their cross-sectional configuration) merging directly into one another.
  • a feeder body produced in a corresponding core box can be removed from the core box in the direction of the longitudinal axis after it has been produced.
  • the core box accordingly has on its inner side, which defines the outer contour of the feeder body, projections or recesses that taper in a straight line and extend in a straight line.
  • the outer contour projections have a chamfer on their (front) side facing the feeder opening, it being possible for adjacent projections in the circumferential direction to have different angles of the chamfer.
  • the projections of the outer contour can be pointed or rounded.
  • the figures show a feeder body 1 that has a peripheral side wall 2 that extends from a base area 11 along a longitudinal axis 7 to a cover area 12 .
  • the side wall 2 delimits a feeder cavity 4 with an inner contour 14.
  • the feeder cavity 4 is adjoined by a feeder opening 5, via which the feeder cavity 4 is connected to the mold cavity of the casting mold during the casting process.
  • the side wall 2 On its outside, the side wall 2 has an outer contour 3 with a large number of outer contour projections 6 extending along the longitudinal axis 7, which are arranged one behind the other in the circumferential direction of the feeder body 1 and, starting from the base area 13, extend over approximately three quarters of the length of the feeder body 1 .
  • the feeder body 1 thus has a lamellar outer contour in the lower area.
  • FIG. 2 shows that the outer contour projections 6 have a width 8 that increases along the longitudinal axis 7 from the base area 11 to the cover area 12, so that the width of a cavity 10 between two adjacent outer contour projections 6 decreases.
  • the cross-sectional configuration of the inner contour 14 proceeds along the bottom region 11 having the feeder opening 5 the longitudinal axis 7 towards the cover area 12 tapers. It is thus possible to produce the feeder body 1 in a single process step without a lost core in a core box.
  • the feeder insert shown in the figures has, in addition to the feeder body 1, a sleeve 9 which surrounds the lower area of the feeder body 1 in the area of the outer contour projections 6 in the circumferential direction.
  • the inside of the sleeve 9 rests on the outside of the outer contour projections 6 in the area of the side wall 2 .
  • the sleeve 9 also covers the bottom area 11 of the feeder body 1, with an opening 13 in the sleeve 9 being smaller than the feeder opening 5.
  • the shell 9 prevents molding material from getting between the outer contour projections 6 during the molding process, so that cavities 10 filled with air are formed, which are delimited by adjacent outer contour projections 6 and the shell 9 and at their upper ends by the feeder body 1 itself. These cavities 10 provide insulation during the casting process.
