Diecasting tool for the production of a cylinder crankcase (), comprising a salt core () and at least one cylinder sleeve (), wherein the cylinder sleeve () comprises an upper end () on the cylinder head side, and a lower end () on the crankshaft side, and the cylinder sleeve () is supported on at least one center sleeve that is disposed on the diecasting tool, and the salt core () at least partially surrounds the cylinder sleeve () in the manner of a cladding, wherein the salt core () comprises a crown () that at least partially bears on one of the ends () of the cylinder sleeve (), and the core () comprising openings () that extend vertically beneath the end () of the cylinder sleeve () on the cylinder head side.

Diecasting tool arrangement

A die casting machine has a divisible die casting tool. To be able to die cast in a secure manner large die-cast parts beyond elasticity-caused limits of the machine construction, the locking pressures for the die casting tool are transmitted by tool-integrated tie rods into a power flux circuit remaining within the die casting tool. In the closed condition of the die casting tool, the tie rods can be anchored in a tension proof manner on both sides of its mold parting surface in the die casting tool and, for the opening, can be detached at least from one of the tool parts of the die casting tool. For limiting the flow paths of the molten mass, several casting cylinders for feeding the casting material into the casting mold are distributed thereon so that the casting mold can be filled simultaneously from several points. For adapting the die casting machine to different die casting tools, the casting cylinders are adjustably held in their position parallel to the parting plane of the tool halves and can be fixed in the respective adjusting position.

Die casting machine

Methods for casting thin-walled structural elements made of alloy for automobile bodies using the diecasting, thixocasting, or thixoforming methods, as well as corresponding structural elements are described. In order to produce by these methods in particular body side wall parts including the A, B and C pillars, the castings are cast in several casting slices. The casting slices of a casting are cast, staggered timewise in succession using the same method and from the same alloy but in different casting molds or different parts of a casting mold. At the seams, the casting slices are cast together along a defined shapewise contour. The casting slices can be case together indirectly with interposition of a separate seam strip. However, they can also be cast onto one another, with an already cast first casting slice being placed in a second casting mold and cast together therein with the second casting slice. Complete body side wall parts are cast in three casting slices, with the seams being located in the roof and sill areas.
