Abstract

The subject of the invention is a process for the production of at least partly thin-walled and aluminium castings with sand moulding technology by gravity casting, which allows producing casts with 100 times or favourably 200-400 times larger overall dimensions in case of 1-3 mm wall thickness. The main idea of the process is that sand mould containing mould cavity is provided, melt of aluminium content is produced, the melt is introduced into the mould cavity at several points through a gating system of narrowing cross section. A further subject of the invention is a sand mould fitted with a gating system to produce at least partly thin-walled castings with sand moulding technology, by gravity casting. The wall thickness of thin-walled segments is 1-3 mm and the largest dimension is more than a 100 but favourably at least 200-400 multiple of the wall thickness. The main idea behind the sand mould with a gating system is that it contains a mould cavity allowing the production of at least partly thin-walled castings, and is equipped with a gating system, which is composed of at least two sprues and one ingate to each having a porthole into the mould cavity and in liquid contact with the sprues.

Claims

AMENDED CLAIMS received by the International Bureau on 12 January 2017 (12.01 .2017) Patent Claims
1. Casting process for producing at least partly thin-walled aluminium castings with sand mould technology by gravity casting, wherein wall thickness of a thin-walled part is 1 -3 mm, characterised by:
- providing a sand mould comprising a mould cavity,
- producing a melt of aluminium content,
- introducing the melt into the mould cavity at multiple points through a gating system of narrowing cross section.
2. The process according to claim 1 characterised by producing a casting the largest overall dimension of which is more than 100 times, preferably at least 200-400 times of the wall thickness.
3. The process according to claims 1 or 2 characterised by providing a gating system of narrowing cross section for the mould cavity which contains at least two sprues each being in liquid communication with at least one gate respectively, each gate having an inlet opening into the mould cavity.
4. The process according to claim 3 characterised by providing liquid communication between at least two gates and at least one sprue with a runner, and the overall cross section of the inlets of the gates opening from one runner is at least two times smaller, more preferably 3-5 times smaller than the overall cross section of branches of the given runner.
5. The process according to claims 3 or 4 characterised by providing 2-4 gates per each runner, and selecting the number of gates and runners such that a thin-walled casting portion having a dimension of 100-1000 cm2 is cast from one gate.
6. The process according to any one of claims 2 to 5 characterised by selecting the height of the sprue such that the drop between the upper inlet opening of the sprue and a parting plane of the sand mould is at least 0.1 times greater, preferably 0.6-1.3 times greater than the largest dimension of the casting to be produced.
7. The process according to any one of claims 1 to 6 characterised by preheating the sand mould before starting the casting at least in the segments of the thin-walled parts of the casting to at least 100°C but preferably to 200-600°C and even more preferably to 300-500°C. 16
8. The process according to claim 7 characterised by providing a cooling metal insert in the sand mould and heating the cooling metal insert prior to starting the casting until vapour is precipitated and the insert's surface becomes dry.
9. The process according to any one of claims 1 to 8 characterised by that prior to being poured into the gating system, the melt is overheated by at least
100°C, preferably by 200°C, more preferably by 200-350°C with respect to the melting point.
10. Sand mould provided with a gating system for producing at least partly thin-walled aluminium castings with sand moulding technology by gravity casting, wherein wall thickness of a thin-walled part is 1 -3 mm and the largest dimension of the thin-walled part is at least 100 times, preferably at least 200-400 times greater than the wall thickness, characterised by that the sand mould contains a mould cavity for producing the at least partly thin-walled casting piece, and is provided with a gating system of an overall narrowing cross section, which contains at least two sprues each being in liquid communication with at least one gate respectively, each gate having an inlet opening into the mould cavity.
1 1 . Sand mould provided with a gating system according to claim 10 characterised by having a runner providing liquid communication between at least one sprue and at least two gates.
12. Sand mould provided with a gating system according to claim 1 1 characterised by that the overall cross section of the inlets of the gates opening from one runner is at least two times smaller, preferably 3-5 times smaller than the overall cross section of branches of the given runner.
13. Sand mould provided with a gating system according to claims 1 1 or 12 characterised by comprising 2-4 gates per runner and the number and layout of the gates and runners is chosen such that each part of the sand mould producing a thin- walled casting portion having a dimension of 100-1000 cm2 is provided with at least one gate.
14. Sand mould provided with a gating system according to any one of claims 10 to 13 characterised by that the sprue comprises a sprue part formed in the sand mould and an attachement joined to it from above.
15. Sand mould provided with a gating system according to any one of claims 10 to 14 characterised by that the drop between the upper inlet opening of the sprue 17
and a parting plane of the sand mould is at least 0.1 times greater, preferably 0.6-1 .3 times greater than the largest dimension of the mould cavity.
