  • Patent number: 10850321
    Abstract: A foundry core formed from a moulding sand, grains of which are bound together by a binder, and which is provided to form a cooling channel in an engine block for an internal combustion engine. The foundry core has a supporting section, two neck sections, which protrude from a lateral surface of the supporting section and are arranged at a distance from one another, and at least one bridge section which is held by the neck sections at a distance from the supporting section and a minimum thickness of which measured as the distance between its lateral surfaces is no more than 3 mm in an area which lies between the neck sections.
    Type: Grant

  • Patent number: 9895745
    Abstract: A method for demolding a casting from a casting mold having at least one casting core which images a passage opening in the casting connecting two outer sides of the casting and is produced from a molding material bound by a binder which decomposes under the influence of temperature, wherein the casting mold undergoes a heat treatment in a furnace for the demolding, during which it is heated to a temperature at which the binder loses its binding effect. In the furnace, hot gas is flowed through a passage formed in the casting core of the casting mold, the temperature of the hot gas corresponding at least to the temperature at which the binder of the molding material loses it binding effect such that the casting core decomposes into fragments or separate sand particles as a consequence of the influence of the hot gas.
