Definitions

  • the invention relates to an insert core for the production of a mold and the Process for producing a mold according to the features of the preambles of independent main claims.
  • the coated molding sand Due to a chemical reaction, the coated molding sand a firm joint. After a layer thickness of approx. 0.2 mm has been scanned, the tool table is lowered and the next one Filled in sand layer. This makes the laser sintering system suitable for direct Creation of sand molds and cores of any complex structure.
  • the metal insert core does not have to be cast, it can be opened simple way by mixing the metal granules with the binder getting produced. Due to the higher thermal conductivity of the metal insert core compared to the sand cores normally used, there is an accelerated Cooling of the molten metal to be poured later. As a result of the quick progressive solidification creates a relatively fine-grained and dense Structure that has better strength properties. So there is an overall time and cost effective method available that the well known rapid prototyping Procedures supplemented sensibly.
  • a cooling device e.g. in form of a Integrate cooling water spiral.
  • the insert core is produced in a simple manner using the sand sintering process a negative form of the insert core is made, into which the mixture will later be made Metal granulate and binder is filled.
  • a lost mold is made from coated molding sand for a combustion chamber insert core (see Fig. 1) manufactured in the sand sintering process.
  • a hot air dryer or similar post hardened sand mold for the combustion chamber insert core is a mixture of metal granulate and two-component binder filled.
  • the metal granulate can be made of stainless steel, copper, brass or the like.
  • the two-component binder is here Embodiment around NOVATHEN 540 (chemical name: pre-catalyzed polyol Ashland), which is usually used together with the second component NOVATHEN 260 is used to manufacture sand cores and sand molds for aluminum casting.
  • NOVATHEN 540 chemical name: pre-catalyzed polyol Ashland
  • the metal granulate with the first is first Binder component NOVATHEN 540 mixed before the second binder component NOVATHEN 260 is added and mixed as well.
  • the combustion chamber insert core can be removed from the mold be broken out, the form itself being destroyed (lost form). to can further increase the thermal conductivity during the subsequent casting of the molten metal additionally in the insert core e.g.
  • a copper spiral can be integrated by this while filling the combustion chamber sand sinter with metal granulate and the two-component binder is embedded in it.
  • the rest for making one Sand molds or sand cores required in the cylinder head housing are also in the Sand sintering process is produced and, as shown in FIGS. 2 to 4, into one Total mold assembled.
  • the bottom core 2 the Combustion chamber core 4 and the water jacket insert core 6 for the later water-cooled Cylinder head housing can be seen.
  • there is the mold continue from four side cores 8, 10, 12, 14, which have a corresponding Gearing profile are placed on the bottom core 2.
  • a lid core 16 is placed at the end.
  • the lid core 16 has three cylindrical openings 18 into which, as shown in FIG. 5, so-called ceramic insulating feeders 20 to accommodate the actual mold expanding melt are inserted.
  • slot-shaped shafts 22 are, as shown in Fig. 5, metal tubes 24 in the Inserted aluminum melt. Since it is cast by the binder portion in the Quartz sand produces a high amount of gas, which leads to considerable casting errors can, the gas is specifically discharged to the outside via the metal tubes.
  • the in Cover core 16 diagonally offset cylindrical openings 26 serve to fill the molten metal. For this purpose, as shown in FIG. 5, Filler 27 placed on the openings 26.
  • a metallic insert core consisting of a metal granulate and a Two-component binder is not made to produce one Cylinder head housing restricted.
  • sand sintering as a rapid Prototyping processes can be used to generate any component geometries, which are used as cores can be used for the production of metal castings.
  • the shape for making the piston consists of a sand-sintered lower part 28, in which a metallic insert core 30 with a cylindrical recess 32 for forming a cylindrical piston crown is inserted.
  • the metallic insert core 30 also made of a metal granulate and a two-component binder produced, the negative form for the insert core 30 a sintered form is also used.
  • On the lower part 28 is a sand sintered top 34 placed next to the recess 36 for the Forming the piston skirt a channel 38 for pouring the aluminum melt as well as a ceramic insulating feeder 40 for receiving the upper part 34 expanding aluminum melt.
  • a cooling device in the metal insert core 30 integrated in the form of a water-conducting cooling spiral 42. So that during the Pouring off the molten aluminum accelerated cooling of the solidifying Melt reached.
