Definitions

  • the invention relates to a device for producing a multilayer molded article according to the preamble of claim 1 and to a method which can be carried out by means of the device according to the preamble of claim 9.
  • Moldings which have a two-layer structure are known in particular as so-called "carbon brushes", which are used, for example, in small motor engineering as current-carrying connection parts which enable a contact pick-up at the collector of an electric motor.
  • carbon brushes both a To make tap on the rotating collector as well as a secure electrical connection with electrical wire leads, there are special requirements for the material composition of the carbon brushes, which have led to the carbon brushes a coal part formed essentially exclusively of compressed carbon particles and a substantially pressed out Having copper particles formed conductor terminal part.
  • a corresponding two-layer structure of the carbon brushes is therefore state of the art.
  • the production of the known carbon brushes takes place in such a way that the corresponding volumes of material are introduced into a mold and pressed axially against each other, such that a segment-like structure of the carbon brushes results with layers of layers stacked in the pressing direction.
  • the directional pressing operation results in an anisotropic electrical characteristic for the carbon brushes with a maximum electrical component resistance in the pressing direction, which coincides with the current-carrying direction.
  • the present invention is therefore based on the object to propose a device which allows the production of two- or multi-layer mold parts with reproducible layer structure.
  • the device according to the invention has the features of claim 1.
  • the inventive apparatus for producing a multilayer molded article having at least a first and a second mold layer comprising a multi-part, a mold body and a mold slide assembly comprising mold and a coaxial with the mold slide assembly forming die, wherein the mold slide assembly for forming a plurality of mold segments in the mold in their Configuration is variable and the mold slide assembly and the forming die for opening and closing of the mold are movable relative to each other.
  • the mold slide assembly has a plurality of variable in their relative arrangement form slide parts, so that the required according to the formation of the desired mold segments configurability is achieved with a compact design of the mold slide assembly.
  • the number of mold slide parts corresponds to the number of mold segments, since the required configurability is thus achieved with the least possible number of components.
  • the mold slide parts cooperate with the mold body to define segment separation surfaces between the mold segments.
  • the mold slide parts cooperate with the mold body in such a way that they define mold segments.
  • a particularly simple way of positioning the delivery of the filling device for successive filling of the individual mold segments results when the filling device is movable transversely to the axis of the forming die.
  • a multi-part, a molding and a mold slide assembly comprehensive mold cooperates with a forming die, wherein a filling defined by the selected configuration of the Formschiebcran onion in the molding Shape is such that in a direction transverse to the axis of the forming die side by side formed mold segments are successively filled in time with mold material and subsequently carried out by a relative movement of the forming punch and the mold slide assembly forming the molding.
  • the inventive method allows due to the use of a variable in its configuration mold slide assembly, the formation of defined shape segments in the mold, which allows in conjunction with the temporally successive filling of the mold segments, the formation in their dimensions exactly defined shape layer.
  • the molded articles produced by means of the method according to the invention are thus exactly reproducible in their structure and correspondingly have precisely defined electrical parameters.
  • the first mold segment first transfers the mold slide arrangement into a first mold slide configuration corresponding to the first mold segment and the first mold segment is assigned a first material reservoir with molding material and subsequently the mold slide arrangement is filled into a first mold segment transferred to the second mold segment corresponding mold slide configuration and the second mold segment is assigned a second material reservoir with mold material and then carried out a common compression of the mold segment fillings.
  • the subsequently performed common compaction process of previously defined separately in the associated mold segments in their material volumes Formschiehten allows both the formation of a defined in their topography as well as in their position in the molded body boundary layer between the mold layers.
  • the filling of at least one mold segment takes place in such a way that initially the mold segment is formed with oversize and after the mold segment has been filled, an adjustment of the mold segment to the desired shape is achieved.
  • a pre-compression of the molding material arranged in the respective molding segment is effected, which prevents unwanted mixing of the molding materials assigned to the different molding layers during the subsequent compacting process, even in the case of direct contact with a molding material volume arranged in an adjacent molding segment.
  • the risk of mixing can also be reduced by providing already filled mold segments with a cover for filling a mold segment.
  • the application of the method according to the invention or the use of the device according to the invention makes it possible to produce a multilayer carbon brush with at least one first mold layer of a first mold material and a second mold layer of a second mold material, wherein between two adjacent mold layers and substantially parallel to one Contact surface of the carbon brush, which is associated with a sliding contact surface of a commutator of an electric motor, a layer separation surface is formed.
  • the contact forming surface serving for forming the contact surface has abrasive properties.
  • the multi-layer carbon brush according to the invention allows due to the defined separation between the mold layers with a parallel to the contact surface separation surface in the direction of wear of the multilayer carbon brush precisely defined caesura, which makes it possible by a corresponding thickness dimension of the contact mold layer in the direction of wear, the multi-layer carbon brush as well design that abrasive properties are given only until a defined wear, which is determined by the location of the layer separation surface.
  • the contact molding layer has a carbon material with an abrasive additive in order to achieve an abrasive effect with sufficient electrical qualities of the molding layer.
  • a particularly high abrasion performance can be achieved if an abrasive ceramic material is used as the additive.
  • a particularly high degree of reproducibility of the abrasion effect can be achieved if a homogeneous distribution in the contact molding layer is selected for the aggregate.
  • an adjacent the contact Forming layer arranged, divided by the layer separating surface adjacent neighboring mold layer also has abrasive properties.
  • the abrasive properties of the adjacent molding layer can be generated in the same manner as described above with respect to the contact molding layer.
  • the two-phase or multi-phase intake process described above leads to good results, in particular, when the abrasive effect of the contact mold layer is greater than the abrasive effect of the adjacent mold layer, so that a so-called “fine grinding” can be carried out by means of the abrasive effect of the neighboring mold layer is.
