Abstract

Apparatus is provided for casting solid objects. A mould has a recess defined in its top surface, and has a cavity with a sprue that opens into the recess. A plug having a closed top end is immovably attached to the mould and located at least partially within the recess. A receptacle to hold liquid feedstock has an aperture in its base, and the top end of the plug is of a reciprocal shape to the aperture such that it can seal the aperture. The receptacle is supported by a frame. The mould may be moved towards the crucible so that the plug seals the aperture, and moved away from the crucible to allow melted feedstock to flow out of the aperture and into the sprue.

Claims (23)

1. Apparatus for casting solid objects, comprising: a mould having a recess defined in its top surface, and having a cavity with a sprue that opens into said recess; a plug having a closed top end, immovably attached to said mould and located at least partially within said recess; and a receptacle to hold liquid feedstock having an aperture in its base, wherein said top end of said plug is of a reciprocal shape to said aperture such that it can seal said aperture.
2. Apparatus according to claim 1 , wherein: said plug further comprises an outside wall defining an internal void; said wall has ports defined therein giving access to said internal void; and the bottom end of said plug is open; such that a flow path is defined from the outside of said plug through at least one of said ports and out of said bottom end.
3. Apparatus according to either of claims 1 or 2, wherein said plug is located above said sprue.
4. Apparatus according to any of claims 1 to 3, wherein the bottom end of said plug is formed with an external helical thread, and said mould defines an aperture having a cooperating internal thread, such that said plug is attached to said mould by being screwed in.
5. Apparatus according to any of claims 1 to 3, wherein the bottom end of said plug is formed with extending members that are attached to said mould.
6. Apparatus according to claim 1 , further comprising a support to hold said receptacle.
7. Apparatus according to claim 6, wherein said recess is shaped such that the base of said receptacle fits into the top of said recess.
8. Apparatus according to either of claims 6 or 7, wherein said support is a frame configured to fit over said mould, with an aperture defined in the top of said frame and configured to fit around said receptacle; and said receptacle comprises external support members to rest on said frame.
9. Apparatus according to any of claims 6 to 8, further comprising moving means for moving said mould towards and away from said receptacle.
10. Apparatus according to claim 9, wherein said moving means is a scissor jack located underneath said mould.
11. Apparatus according to any of claims 6 to 10, wherein said receptacle is a crucible.
12. Apparatus according to claim 11 , further comprising a furnace containing said mould and plug, said support, said receptacle, and said moving means.
13. Apparatus according to any of claims 6 to 10, wherein said receptacle is a ladle.
14. Apparatus according to either of claims 9 or 10, wherein said mould is located on top of said moving means, said receptacle is mounted in said support, the base of said receptacle is within said recess, and said aperture is directly above said plug.
15. A method of forming a solid object, in which: a mould has an internal cavity with a sprue, and a recess defined in its top surface into which said sprue opens; a plug is attached to said mould within said recess; and a receptacle is mounted above said mould such that an aperture in the base of said receptacle is sealed by the top end of said plug; said method comprising the step of: moving said mould downwards and away from said receptacle, such that said plug is removed from said aperture; whereupon liquid feedstock within said receptacle flows out of said aperture, into said recess and into said sprue in order to fill said cavity.
16. A method according to claim 15, wherein: said plug further comprises an outside wall defining an internal void; said wall has ports defined therein giving access to said internal void; and the bottom end of said plug is open; such that the path for said liquid feedstock from said recess to said sprue passes through said plug, via at least one of said ports, said internal void, and said bottom end.
17. A method according to either of claims 15 or 16, wherein said plug is located above said sprue.
18. A method according to any of claims 15 to 17, wherein said plug is attached to said mould using a screw fit at the bottom end of said plug.
19. A method according to any of claims 15 to 17, wherein said plug is attached to said mould by members extending from said bottom end attached to said mould.
20. A method according to claim 15, wherein said receptacle is mounted above said mould using a support frame.
21. A method according to claim 15, wherein the base of said receptacle is smaller than said recess such that it fits into said recess.
22. A method according to any of claims 15 to 21 , wherein said mould is placed on a scissor jack, and said step of moving said mould comprises lowering said scissor jack.
23. A method according to any of claims 15 to 22, further comprising the earlier steps of: placing said mould underneath said receptacle such that said plug is directly beneath said aperture; moving said mould towards said crucible so that the top of said plug seals said aperture.
