Definitions

  • the present invention relates to an apparatus for casting cast iron in a mold having a multi-part metallic mold enclosing a sand mold into the cavity of which the molten cast iron is filled.
  • a device is out DE 699 23 214 T2 known.
  • a controlled cooling of the material after filling the sand mold is to be achieved in that the plurality of mold parts coolant-flowed cavities and these are acted upon by the coolant according to the desired cooling conditions.
  • the US 2005/0103407 A1 shows a mold for a cylinder head with a metallic molding and several sand moldings. After casting, the metallic molding is removed to quench the casting and the exposed portion of the casting is sprayed with cooling water and cooled in this manner.
  • the WO 00/27567 A1 shows an apparatus for casting cast iron in a mold with a multi-part metallic mold enclosing a sand mold, in the cavity of the molten cast iron is filled.
  • the object of the invention is to achieve not only a better cooling but also a better controllability of this cooling.
  • the controlled in this way solidification of the casting should enable the achievement of optimal, reproducible material and structural properties in the casting / component.
  • the two-part metallic mold 1 encloses a sand mold 3, in which the casting room or after ascending filling by gates 6, the casting is located.
  • This sand mold can be made in a conventional process such as croning, cold box or hot box processes.
  • In the inner wall of the mold 1 and in the outer wall of the sand mold 3 are formed, opposite each other in cross-section semicircular grooves, which complement each other to a channel 2, which extends helically from a coolant inlet 5 to a coolant outlet 8. It is understood that depending on the shape of mold and sand mold other courses of the coolant channel or space may be appropriate, such as a meandering course.
  • the primary cooling is carried out by a coolant channel 2 flowing through the coolant.
  • a coolant channel 2 flowing through the coolant.
  • preferably serves air or, when guided in a closed circuit, an inert gas.
  • this primary cooling is controlled accordingly, in particular on the amount and initial temperature, the flow rate and the pressure of the introduced coolant. Since this maximum reaches the casting and is separated from it only by the remaining thickness of the sand mold, a targeted rapid cooling is achieved, which in turn the achievement of optimum microstructural properties such as strength, elongation, toughness, fine grain u. a. allows.
  • the coolant is a gas, preferably air.
  • the flow of the coolant is effected by introducing the same under pressure at the coolant inlet.
  • the flow of the coolant is effected by sucking the same at the coolant outlet.
  • the coolant flows through a filter before discharge into the atmosphere.
