Definitions

  • the invention relates to a device for casting a cylinder crankcase for an internal combustion engine made of a light metal alloy, wherein the light metal alloy is poured over a gate in a region of the bearing block below a cylinder tube of the cylinder crankcase. Moreover, the invention relates to a cylinder crankcase produced by this method.
  • Engine blocks which are also called cylinder crankcases, are today largely made of light metals.
  • Preferred materials here are aluminum and / or magnesium alloys.
  • a key advantage of these alloys is their low weight, whereby the motor vehicles in which they are used have a low total weight.
  • a homogenous material structure is present in the entire cylinder crankcase. The material structure is also influenced by the position of the gate in the casting machine to be produced crankcase.
  • the DE 100 63 357 B4 generally describes the production of engine blocks made of light metal materials with at least two molded parts, wherein at least one gate for filling the mold with the light metal melt is provided in at least one molded part.
  • the object of the invention is to provide a device with which, on the one hand, high bearing stability can be achieved and with which reduced cycle times can be produced.
  • the object according to the invention is achieved in that the device can be cooled in the area of a side slide forming a bearing block, so that a fine structural formation in the bearing block can be achieved.
  • the device according to the invention it is now possible to fill the cylinder crankcase or the mold for the production of the cylinder crankcase in such a way that the area of the highest volume concentration is directly filled, whereby an optimized temperature gradient results from the position to the gate, so that a homogenous Who forms material structure in the cylinder crankcase. Due to the location of the gate on the outer surface of the cylinder crankcase below the cylinder tubes is the power supply of the bearing block, which forms the region of highest volume concentration, as well as the screw pipes ensured.
  • the cylinder crankcase 1 is shown in one of its possible casting layers in cross section.
  • the cylinder crankcase 1 is limited by a movable mold half 2 and a fixed mold half 3 and the lateral slides 4 and 5.
  • the illustrated cylinder crankcase 1 is a motor with skirt 6, which is also referred to as apron engine.
  • the cylinders 7 are surrounded by openings 8, which form the cooling water jacket 8.
  • Above the upper and below the lower Kntoniganmantel 8 stiffening ribs 9 are shown.
  • the gate 10 is located below the cylinder tubes 7 of the cylinder crankcase 1.
  • the guide bar 11 is located directly on the crankcase of the cylinder crankcase 1, whereby the cylinder crankcase 1 produced by this method is uniquely identifiable.
  • the gate zone Z to be used according to the invention can be located in an area of the skirt 6.
  • the gate 11 can be placed in the area of the stiffening ribs 16.
  • the filling can also take place by means of a suitable gating system by gravity.
  • the manifold 12 which is connected to the riser 13.
  • P of the casting furnace 14 By defined pressurization P of the casting furnace 14, the casting tool 2, 3, 4, 5 turbulence low rising with a light metal alloy, aluminum and / or magnesium-based filled.
  • the method according to the invention has the advantage that the bearing block 15 can be cooled, as a result of which defined cooling and thus a homogeneous material structure can be set.
  • the longest cooling times are due to the process, since here too high volume concentrations are present and the liquid alloy is poured from here into all areas of the casting mold 2, 3, 4, 5 and the densification takes place.
  • the region of the gate very long solidification times, resulting in a coarse-grained structure of the structure, which in turn adversely affects the strength.
  • the inhomogeneities in the gate advantageously do not affect the strength in the highly stressed areas such as bearing block 15 and cylinder surface out.
  • Hypereutectic aluminum-silicon alloys can also be cast by the method according to the invention.
  • the gate position ensures a uniform distribution of the primary silicon, which in turn has a positive effect on the strength of the cylinder crankcase 1.
  • Perpendicular to the sieve chambers in the G confusekammem 12 one or two-piece squeeze-cast-stamp 17 are arranged, through which a re-pressing or feeding of the metal is possible and is achieved by a defined solidification or freezing of the gate area.
  • the squeeze-cast-stamp 17 is movable in the direction of the arrow F.
  • Bornitrit- or graphite-containing ceramic fiberboards can be applied to the wire flanks, which protect the Squezze-Cast punch 17 from the direct action of the light metal alloy.
  • the use of a reduced-height cylinder quill 7 for supplying power to the gate remote screw holes is required.
  • the casting process shown in Figure 1 shows a casting with low pressure, wherein the mold 2, 3, 4, 5 is filled with approximately 0.4 bar.
  • a locking unit is provided in the region 18 of the sprue 10.
  • the locking unit is, for example, a slider which separates the sprue 10 from the distributor 12, so that the still liquid light metal alloy can flow back into the casting furnace 14 after closing the slide and removing the pressure P through the riser 13. If the Abriegelisme is closed, it can by means of the punch 17 a reprint on the Casting 2, 3, 4, 5 exercised and thus counteracted a fading of the light metal alloy.
  • the inventive method is suitable for low pressure, die casting and squeeze casting, which represent general methods for producing cylinder crankcases.
