Holding device for holding a casting core in a casting mold
A holding device for holding a casting core in a casting mold, especially in a die-casting mold, includes a plurality of clamping sections which are positioned in relation to each other in such a way that a clamping region for a casting core is formed.
1. A holding device for holding a casting core in a casting mold, comprising:
a plurality of clamping portions, wherein the plurality of clamping portions are each a separate structure, wherein the separate structures are arranged in respective pairs opposite one another to form a respective clamping region for the casting core, and wherein a first clamping portion of a respective pair is oriented perpendicularly to a second clamping Portion of the respective pair;
wherein each of the plurality of clamping portions has a first member and a second member wherein the first and second members longitudinally extend perpendicularly to each other in different respective planes;
wherein each of the first member and the second member has an inner contact face configured to bear against the casting core and an outer contact face configured to bear against the casting mold, wherein the respective inner contact faces of the first and second clamping portions of the respective pair face the respective clamping region;
wherein the inner contact face is disposed on a first side of the respective member and the outer contact face is disposed on a second side of the respective member wherein the first side is opposite from the second side.
2. The holding device according to claim 1 , wherein
the clamping region is configured for a force-fitting arrangement of the casting core.
3. The holding device according to claim 1 , wherein
the plurality of clamping portions form a lattice structure or web structure.
4. The holding device according to claim 1 , wherein
a material of the holding device is identical or similar to a casting material that is used for producing cast parts.
5. The holding device according to claim 1 , wherein
the respective inner contact faces are configured to bear against the casting core fully and in a form-fitting manner.
6. The holding device according to claim 1 , wherein
a respective recess is formed in the respective outer contact faces.
7. A casting mold, comprising:
at least one casting core; and
at least one holding device according to claim 1 , wherein
the at least one holding device is arranged between the at least one casting core and the casting mold.
8. The casting mold according to claim 7 , wherein
the mold is a die casting mold.
9. The casting mold according to claim 7 , wherein
the at least one holding device is arranged between the at least one casting core and the casting mold in a force-fitting manner.
10. The casting mold according to claim 7 , wherein
an interference fit is provided between the at least one holding device and the casting core.
11. The casting mold according to claim 10 , wherein
an interference fit is provided between the holding device and the casting mold.
12. The casting mold according to claim 7 , wherein
an interference fit is provided between the holding device and the casting mold.
13. A method for fixing/holding a casting core, comprising the steps of:
providing a casting mold and a casting core;
providing a holding device according to claim 1 ;
arranging the holding device between the casting mold and the casting core in order to fix the casting core.
14. The method according to claim 13 , wherein the casting mold is a die casting mold.
15. The method according to claim 13 , further comprising the steps of:
arranging the holding device on the casting core;
inserting the casting core into the casting mold.
16. The method according to claim 15 , further comprising the step of:
closing the casting mold in order to fix the casting core and the holding device.
17. The use of a holding device according to claim 1 in a die casting mold for core fixing.
