Definitions

  • the present invention primarily relates to a closed one Feeder insert, hereafter also called feeder for use in Pouring of metals in molds, with the features according to the preamble of claim 1, so as known from US-A-5,462,106.
  • Such feeder inserts are used in the manufacture of a casting mold integrated into these and form a space surrounded by molding material, the has a passage (passage) to the mold cavity and during casting is filled by the casting flow with liquid metal, which during the Freezing process flow back to the casting and the volume deficit at to compensate for the solidification of the casting.
  • so-called voids which are shrinkage cavities, which are caused by the Metal volume contraction during the solidification process arise
  • the module (volume to surface ratio) of the feeder must be larger than that of the casting.
  • the walls of the feeder become common from an exothermic material, such as an aluminothermic Mixture, formed.
  • an exothermic material such as an aluminothermic Mixture
  • the molding material usually molding sand, in individual cases also other granular materials
  • the molding material is then compacted and the feeder thereby more or less firmly from the compacted Molded material included.
  • Spring pins are as well as fixed (rigid) mandrels intended to keep a feeder insert in a predetermined position.
  • she usually comprise (a) a tubular element for attachment to a model plate, (b) one disposed in the tubular member Spring and (c) a spring resting on the spring, longitudinally within the tubular element telescopically displaceable spike tip element.
  • a spring mandrel is usually on the model plate (model surface) attached, and then a feeder insert is placed on it, whose lower surface is in the starting arrangement before filling the Formstoffs located at a predetermined distance from the model surface.
  • the separation of the so-called residual feeder i.e. the casting remaining in the feeder insert, solidified metal
  • the breaking point i. the mental Interface between casting and feeder, but in a considerable Distance from the casting, somewhere in the range of often several centimeters wide sand gap between casting and feeder insert.
  • refractive cores also as constricting, knock-down or collar cores
  • the cleaning effort is therefore usually quite high.
  • Spring pins are also quite expensive and susceptible to wear.
  • the footprint of the specified feeder should be included preferably be dimensioned small without relevant stability disadvantages can.
  • the feeder insert should also be put together can be used with a breaker core, the separation of the residual feeder facilitated by the casting.
  • a breaker core is doing in Frame of the present text as part of the feeder insert understood and not as a separate component.
  • the task is solved by specifying a closed Feeder insert of the type mentioned with the further features according to characterizing Part of claim 1.
  • the displaceability of the first and second form element into one another causes the during a conventional compression process in the feeder longitudinal direction acting on the feeder insert according to the invention high Compression pressures (compression forces) do not lead to its destruction, but only tolerated by the compressibility of the surrounding molding material (molding sand) limited insertion of the one element element in the other one.
  • the footprint of the feeder insert can small and the Suiterwandung be comparatively thin.
  • the form elements should be out of their original configuration, i. out the relative arrangement, which is for the mold elements before wrapping the Feeder insert is provided with molding material, at least 5 mm, preferably can be pushed together by 10 mm.
  • the feeder insert can meet the requirements of the individual case corresponding, for example, in the manner of a compact or ball feeder designed or with a nearly cylindrical top in the upper riser be provided.
  • spring mandrels with the feeder inserts according to the invention is therefore not excluded, but usually can but on it be waived.
  • a preferred feeder insert according to the invention is therefore in particular, for use with a centering mandrel can be designed as a self-centering feeder.
  • a self-centering Feiser has one or more wall sections that towards the top in operation (opposite the feeder passage) Rejuvenate the end wall of the feeder so that a spike tip when positioning the feeder insert along these sections into theirs Target position is guided.
  • a centering provided for receiving the mandrel tip cf. our DE utility model 93 03 392.
  • a self-centering feeder according to the invention especially suitable for use on fast molding equipment.
  • First and second form element of a feeder insert according to the invention can be glued together after production or otherwise get connected.
  • the form elements can also be used as separate parts stored and combined (stacked) as needed.
  • Identical first (or second) form elements can be with style (e.g., in size) different second (or first) features be combined to respective feeder inserts according to the invention.
  • the holding elements are preferably an integral part of respective formula elements, and they can be used in the manufacture of each Moldings without additional step to be molded to this. It can in particular with them stand or clamping projections, circumferential Stand rings, engageable with complementary recesses pins or the like. It is important in each case that the holding elements are designed so that they in the foundry, if first and second Form element still present approximately in their initial arrangement, the molding material but already filled in the molding box, by the subsequent Molding material compaction process of its associated form element can be separated or at least so far deformed that first and telescoping second mold element.
  • the retaining elements are therefore preferably only over small connecting surfaces with their associated Form element connected.
  • retaining elements As an alternative to the use of retaining elements is the use of a Spring mandrel.
  • a Spring mandrel Such a can namely a second, in operation upper Shaping element in the intended starting position relative to the model surface and hold the first mold element without the invention
  • Feeder insert itself includes holding elements. But spring thorns like mentioned in the beginning are quite expensive and susceptible to wear, is their use limited to exceptional cases.
  • this is closer to the passage of the feeder sleeve or this forming first mold element designed so that it (optionally after separation or deformation of holding elements) in the second mold element can be inserted.
  • the outside dimensions of the first, in Operation lower, the casting closer molding element are therefore preferred smaller than the inner dimensions of the associated second, in operation upper Form element.
  • This embodiment is compared with the reverse one (Also inventive) embodiment in which the upper in operation Form element in the lower mold element can be inserted, advantageous because it ensures that during the filling process no disturbing quantities Mold material penetrate into the first mold element.
  • the first, im Operation lower mold element is designed so that it (telescopically) in the second mold element can be inserted, wherein the outer wall of the first element form fit into the inner wall of the second element element intervenes.
  • the gap width between the outer wall of the first Formulas and the inner wall of the second formula element is in the intended output arrangement of the mold elements, if necessary is characterized by the position of the holding elements, preferably maximum 3 mm, advantageously not more than 1.5 mm.
  • the mold elements should be made of their intended, if necessary by the holding elements defined output arrangement out in the feeder longitudinal direction by at least 5 mm, preferably by at least 10 mm into each other let it before, due to the further nesting forces occurring between the form elements to break or Breaking of the first or second formula element comes.
  • the first and / or the second form element includes one or more guide elements that are arranged a tilting or tilting of the two form elements relative to each other at least substantially prevent, if this (from the starting arrangement out) along the feeder longitudinal axis into each other become.
  • These guide elements preferably have the shape in Feeder longitudinally extending thin strips or beads, and she are advantageously located on the outer wall of that element, which can be inserted into the partner mold element; in In a large number of cases they are on the outside of the first one Formula elements arranged.
  • a breaking edge if necessary Part of a breaker core, which is then in operation directly on the model plate can be put on.
  • This integration of a breaking edge (of a refractive core) ensures a significant reduction in the foundry business Putzaufwands in comparison with the known feeder inserts, the Use with spring thorns are provided and therefore no breaking edge (no breaker core) own.
  • the footprint of the feeder according to the invention especially when using a crushing edge (a refractive core) very kept small.
  • the feeder insert according to the invention or the associated form elements may be partially or completely made of insulating or exothermic molding compounds be prepared. If a breaker core is integrated into the first shaping element, so this is typically not exothermic, the associated second Form element will then often be exothermic.
  • the feeder inserts according to the invention comprise two or more Shaped elements that are combined according to demand when stored separately can.
  • the invention therefore also relates to a kit for manufacturing a feeder insert according to the invention, comprising a first mold element and a second mold member which can be arranged to be along a feeder longitudinal axis are slidable.
  • preferred Embodiments of belonging to the kit form elements are the above to remove the feeder insert according to the invention.
  • the molding machine comprises in the usual way a model plate (i.e., a patterning machine for molding machines, usually consisting of a flat plate with cast-in or mechanically fastened models), and the first mold member is preferably arranged to project the compression process in direct contact with the model plate (the Model surface) stands. This is especially true when in the first Form element is integrated a breaker core.
