  • Patent number: 8302659
    Abstract: A method and a device for casting a cast part from a metal melt. A casting mould in a pivoted mounting comprising a mould cavity shaping the cast part, a feed system and a pour channel, is rotated into a fill position and filled with metal melt. Due to the effect of gravity, the melt flows through the pour channel, wherein the main flow direction of the melt makes an angle relative to the acting direction of gravity. Filling is continued until the casting mould, including the pour channel, is completely filled. Then, the casting mould is sealed with a stopper and rotated into a solidification position, in which the melt in the feed system is pushed against the melt in the mould cavity. The casting mould is held in the solidification position until the metal melt has reached a solidification state in which the cast part can be de-moulded.

  • Publication number: 20090165983
    Abstract: A method for mounting a mould composed of mould parts for casting a cylinder block of an internal combustion engine from a metal melt, includes at least one chill, which forms at least one part section of inner surfaces of a cylinder space of the cylinder block, and is positioned and retained at a wall of one of the mould parts. This method provides for moulds to be mounted with chills provided in a mould cavity. This is achieved by holding the at least one chill in its position at least for a specific duration by magnetic forces, which are exerted by a magnet which is arranged on a side of the wall of one of the mould parts facing away from the at least one chill.

  • Publication number: 20080169080
    Abstract: A casting mould for manufacturing a cast part from a metal melt includes a mould cavity for reproducing a cast part and comprising an inlet for pouring metal melt into the mould cavity and also to a device and a process for casting metal melts of this type. The casting mould provides further optimized casting results even under hard practical operating conditions. In addition, the use or application of the device according to the invention and the process minimizes the risk of jamming during casting. This is achieved in that the casting mould has at least one compensation chamber which is linked to the mould cavity via a channel and comprises at least one portion which is arranged above the maximum filling level (Fmax) of the casting mould during solidification of the metal melt.

  • Patent number: 6205959
    Abstract: In an engine block having cylinder cavities arranged close together, a cooling duct is produced in an intermediate wall between the cylinders by pouring the casting material around a mold core made preferably from a material that is soluble in a liquid, combustible and/or brittle, so that the mold core can easily be removed from the duct once the casting has solidified. In the casting mold, the duct mold core is secured solely at its ends so that a cooling duct is formed that is bordered exclusively by a skin of casting material.
