Definitions

  • the present invention relates primarily to a closed one Feeder insert, also called feeder for short, for use with Pouring metals into molds, with a cavity for receiving liquid Metal.
  • Such feeder inserts are used in the manufacture of a mold integrated into this and form a space surrounded by molding material, the has a passage (passage) to the mold cavity and during casting is filled by the pouring stream with liquid metal that during the Flow solidification process back to the casting and the volume deficit to compensate for the solidification of the casting. In this way the Formation of so-called blowholes (these are shrinkage cavities caused by the Metal volume contraction during the solidification process) prevented.
  • the metal in the feeder solidifies later than the metal of the casting, i.e. the module (ratio of volume to surface) of the feeder must be larger than that of the casting.
  • the modules (ratio of volume to surface) of the feeder must be larger than that of the casting.
  • the walls of the feeder become frequent made of an exothermic material, for example an aluminothermic Mixture, formed.
  • an exothermic material for example an aluminothermic Mixture
  • the molding material usually molding sand, in individual cases also other granular materials
  • Feeder inserts are often designed to be very small.
  • the feeder insert tapers thus considerably towards its top surface, and at Applying the molding material to the molding plate often gives rise to the subsequent problem on that the compression of the molding material in the vicinity of the esophagus insufficiently close to the top surface, which is disadvantageous when casting is.
  • Spring mandrels as well as fixed (rigid) mandrels are designed to to hold a feeder insert in a predetermined position.
  • she typically include (a) a tubular member for attachment a model plate, (b) one arranged in the tubular element Spring and (c) a resting on the spring, in the longitudinal direction within the tubular element telescopically displaceable mandrel tip element.
  • Such a spring mandrel is usually on the model plate (model surface) attached, and then a feeder insert is placed on it, the lower surface of which is in the starting arrangement before the filling of the Molding material is located at a predetermined distance from the model surface.
  • the subsequent filling of the molding material therefore also runs between model surface and feeder (bottom surface).
  • the feeder insert placed on the spring mandrel acts a force in the direction of the model plate that causes the feeder insert against the action of the spring force in the direction of the Model plate is pressed. The in the gap between feeder insert and The molded material layer on the model plate is compressed.
  • the footprint of the feeder insert to be specified should be included preferably be dimensioned small without relevant stability disadvantages can.
  • the feeder insert to be specified should also be together can be used with a crushing core that separates the residual feeder relieved by the casting.
  • a crushing core is in the Framework of the present text as part of the use of food understood and not as a separate component.
  • the task is solved by specifying a closed one Feeder insert of the type mentioned, wherein the feeder insert at least two into one another along a longitudinal axis of the feeder (telescopic) comprises displaceable shaped elements which liquid the cavity for receiving Enclose metal on the side.
  • a first shaped element is closer to Passage of the feeder insert arranged as an associated second Feature.
  • the displaceability of the first and second shaped elements into one another causes that during a normal compression process in the longitudinal direction of the feeder high acting on the feeder insert according to the invention Compression pressures (compression forces) do not lead to its destruction, but only to a tolerated, by the compressibility of the surrounding molding material (molding sand) limited insertion of a molding element into the other.
  • Compression pressures compression forces
  • the footprint of the feeder insert can small and the wall of the feeder is comparatively thin.
  • the shaped elements should be out of their initial arrangement, i.e. out the relative arrangement out for the molded elements before wrapping the Feeder insert with molding material is provided, at least by 5 mm, can preferably be pushed into each other by 10 mm.
  • the feeder insert can meet the requirements of the individual case correspondingly, for example, in the manner of a compact or ball feeder designed or with an almost cylindrical feeder cap in the upper area be provided.
  • spring mandrels with the feeder inserts according to the invention is therefore not excluded, but usually can on it to be dispensed with.
  • a preferred feeder insert according to the invention is therefore set up for use with a centering mandrel, in particular can be designed as a self-centering feeder.
  • a self-centering Suer has one or more wall sections that towards the upper one in operation (opposite the feeder passage) Taper the end wall of the feeder so that a thorn tip when positioning the feeder insert in these along these sections Target position is performed.
  • Is a self-centering feeder according to the invention especially suitable for use on fast molding lines.
  • First and second shaped element of a feeder insert according to the invention can be glued together or otherwise after their manufacture get connected.
  • the shaped elements can also be used as separate parts stored and combined (stacked) as needed.
  • Identical first (or second) form elements can also be constructed (e.g. in size) different second (or first) form elements can be combined into respective feeder inserts according to the invention.
  • the holding elements are preferably an integral part of the respective formula element, and they can be used in the manufacture of each Form elements can be molded onto this without an additional step. It can with them in particular around standing or clamping projections, rotating Stand rings, pins that can be brought into engagement with complementary recesses or act like that. It is important that the holding elements are designed to operate in the foundry when the first and second
  • the molding element is still roughly in its initial arrangement, the molding material but is already filled in the mold box by the subsequent one Molding material compression process from its associated shaped element can be separated or at least deformed to the extent that the first and can slide one another into each other.
  • the holding elements are therefore preferably only via small connecting surfaces with their associated one Form element connected.
  • a Spring mandrel As an alternative to using holding elements, the use of a Spring mandrel.
  • One such can namely be a second one, the upper one in operation Form element in the intended starting position relative to the model surface and hold to the first shaped element without the inventive Feeder insert itself includes holding elements. Since spring mandrels, however, like mentioned at the outset are quite expensive and prone to wear, their use be limited to exceptional cases.
  • This is preferably closer to the passage of the feeder insert this forming the first shaped element so that it (if necessary after separating or deforming holding elements) into the second shaped element can be inserted.
  • the outer dimensions of the first, in Operation of lower form elements closer to the casting are therefore preferred smaller than the internal dimensions of the associated second, upper in operation Form element.
  • This configuration is the reverse of that (Also according to the invention) embodiment in which the upper in operation Shaped element can be inserted into the lower shaped element, advantageous because it ensures that no disturbing quantities are present during the filling process Penetrate molding material into the first molding element.
  • An embodiment is particularly advantageous in which the first, in Operation lower mold element is designed so that it (telescopic) in the second shaped element can be inserted, the outer wall of the first form elements in the inner wall of the second form element intervenes.
  • the gap width between the outer wall of the first Form elements and the inner wall of the second form element is in the intended starting arrangement of the shaped elements, which if necessary is characterized by the position of the holding elements, preferably maximum 3 mm, advantageously not more than 1.5 mm.
  • the shaped elements should come from their intended, if necessary output arrangement defined by the holding elements in the longitudinal direction of the feeder by at least 5 mm, preferably by at least 10 mm leave before pushing due to further nesting Forces occurring between the shaped elements to tear or Breaking of the first or second feature comes.
  • the first and / or the second shaped element comprises one or more guide elements which are set up tilting or tilting of the two shaped elements relative to one another to prevent at least essentially when this (from the output arrangement out) shifted into each other along the longitudinal axis of the feeder become.
  • These guide elements preferably have the shape themselves Thin strips or ridges extending along the length of the feeder, and them are advantageously located on the outer wall of that molded element, which can be inserted into the partner form element; in So in a lot of cases they are on the outside of the first Formula elements arranged.
  • the first molded element is an inventive one Feeder insert integrated a breaking edge, which if necessary Is part of a crushing core, which is then directly on the model plate during operation can be put on.
  • This integration of a breaking edge ensures a significant reduction in Cleaning effort in comparison with the known feeder inserts used for Use with spring mandrels are provided and therefore no breaking edge (no crusher core).
  • the footprint of the feeder according to the invention can be very difficult, especially when using a crushing edge (a crushing core) be kept small.
  • the feeder insert according to the invention or the associated shaped elements can partially or completely from insulating or exothermic molding compounds be made. If a crushing core is integrated in the first shaped element, so this is typically not exothermic, the associated second The shaped element will then often be exothermic.
  • the feeder inserts according to the invention comprise two or more Form elements that can be combined as required when stored separately can.
  • the invention therefore also relates to a kit for manufacturing of a feeder insert according to the invention, comprising a first shaped element and a second shaped element which can be arranged so that they can be moved into one another along a longitudinal axis of the feeder.
  • preferred Embodiments of the form elements belonging to the kit are the above statements to remove the feeder insert according to the invention.
  • the molding machine usually includes a model plate (i.e. a model device for molding machines, usually consisting of a flat plate with cast-in or mechanically fastened models), and the first mold element is preferably arranged so that it is in front the compression process in direct contact with the model plate (the Model surface). This is especially true if in the first Forming element is integrated into a crushing core.
