Definitions
- a water jacket is provided in the cylinder crankcase, which covers the cylinders on both sides and which has a central inlet and a central outlet, with both sides of the water jacket being flowed through approximately uniformly and thus ensuring uniform cooling of the cylinders on both sides.
- a one-piece core element for the production of cylinder crankcases for piston engines is known, which is formed in one piece from the sole core and the two jacket cores.
- the two water jacket cores are not open at the end, so that a clear and reliable fixation in the casting mold results for such a core element.
- the cylinder crankcase according to the invention cannot be produced with such a core element.
- a finished cylinder block can be seen in a top view, which shows a water jacket for a piston engine with cylinders arranged in a row, the water jacket of which is open at the end in each case.
- the mold core arrangement for producing this cylinder crankcase cannot be seen from this prior publication.
- DE-G 90 16 902 shows a three-part water jacket core clip which is designed as a plug-in element.
- This previously known core clip presupposes that the water jacket part cores are each manufactured for themselves and then joined together via the middle piece of the core clip and then connected to the associated sole core.
- the disadvantage of such an arrangement is that the water jacket core must be assembled in a separate joining operation before it can be assembled with the sole core.
- the invention has for its object to provide a mold core assembly for casting an engine block of the type described above, which is easier to assemble.
- the particular advantage of the invention is that the connecting elements are inserted into the core mold during the manufacture of the two water jacket partial cores and incorporated when the core molding compound is shot in, so that after the core molding compound has hardened, this core consisting of two partial cores is handled like a unit and with which can be combined to form a complete core arrangement, the sole core having the cylinder cores.
- the drawing shows a mandrel arrangement for a cylinder bank with, for example, four cylinders in a row arrangement with a divided water jacket.
- the mold core arrangement consists of four cylinder cores 1, 2, 3 and 4, which are molded in one piece from a core molding compound with a sole core 5.
- the core molding compound is shot in a core molding machine in a conventional manner into a core mold which encloses the cylinder cores 1 to 4 and the sole core 5.
- the cylinder cores 1 to 4 are assigned two water jacket parts 6.1 and 6.2, which cover the row of cylinder cores 1 to 4 on the long sides at a distance.
- the two water jacket partial cores 6.1 and 6.2 are designed in such a way that a free space 7 remains on each end.
- the two water jacket parts 6.1 and 6.2 are produced by inserting a connecting element 8 made of sheet metal into the shaping contours of the core shooting machine together in one step, ie in a core shooting process. Due to the enclosed connecting element 8, the two partial water core cores 6.1 and 6.2 can be used practically in the same way in production terms as the otherwise common one-piece water jacket cores.
- the two water jacket part cores are thus firmly connected to one another at the end face via the connecting element 8, for example made of sheet iron, so that the two water jacket part cores 6.1 and 6.2 can be handled as a rigid unit and joined together with the sole core 5.
- the connecting element 8 for example made of sheet iron
- peg-shaped projections are formed on the lower edge side 9 of both water jacket partial cores 6.1 and 6.2, to which corresponding depressions on the shaped surface 10 of the sole core 5 are assigned.
- the two water jacket part cores 6.1 and 6.2 are fixed against one another via the connecting elements 8 provided at a distance from the molding surface 10 of the sole core 5, so that they maintain the predetermined position relative to one another and to the cylinder cores 1 to 4 during the casting process.
- the parts of the connecting elements 8 which are exposed in the region of the front opening 7 are completely melted or melted, so that with the solidification of the melt there is no longer a firm connection between the two water jacket partial cores 6.1, 6.2.
- the connecting elements 8 made of iron sheet are dimensioned in their sheet thickness so that a complete melting is guaranteed at the end of the casting process. This also ensures that the water jacket part cores do not change their position in the casting mold during the feed of the melt.
