Abstract

Disclosed is an apparatus comprising at least one gate and a vessel, the gate being configured to move between a first position to restrict entry into an ejection path of the vessel and contain a material in a meltable form within the vessel during melting of the material, and a second position to allow movement of the material in a molten form through the ejection path. The gate can move linearly or rotate between its first and second positions, for example. The apparatus is configured to melt the material and the at least one gate is configured to allow the apparatus to be maintained under vacuum during the melting of the material. Melting can be performed using an induction source. The apparatus may also include a mold configured to receive molten material and for molding a molded part, such as a bulk amorphous alloy part.

First claim

What is claimed is:

1. An apparatus comprising:
a vessel comprising:
a melt zone configured to receive a material; and
an ejection path adjacent the melt zone and extending along a horizontal direction; and

a gate comprising one or more temperature regulating lines configured to flow a liquid therein to regulate a temperature of the gate during melting of the material, the gate positioned between the ejection path and the melt zone and configured to move between:
a first position to contain the material within the melt zone during melting of the material; and
a second position to allow movement of the material in a molten form past the gate and through the ejection path in the horizontal direction.

2. The apparatus according to claim 1 , wherein:
the gate is positioned at a first end of the melt zone; and
the apparatus further comprises:
a plunger positioned at a second end of the melt zone opposite the first end and configured to:
contain the material within the melt zone during melting of the material; and
move the material in the molten form through the ejection path.

3. The apparatus according to claim 1 , further comprising an actuation mechanism associated with the gate to selectively move the gate between the first position and the second position.

4. The apparatus according to claim 1 , wherein the gate is configured to move along a direction that is oblique to the horizontal direction when moving between the first position and the second position.

5. The apparatus according to claim 1 , wherein the gate is configured to rotate with respect to the vessel when moving between the first position and the second position.

6. The apparatus according to claim 5 , wherein the gate is configured to rotate 90 degrees from the first position to the second position.

7. The apparatus according to claim 5 , wherein the gate is configured to rotate 180 degrees from the first position to the second position.

8. The apparatus according to claim 7 , wherein the gate rotates about an axis that is oblique to the horizontal direction.

9. The apparatus according to claim 5 , wherein the gate comprises a hinge configured to allow rotation of the gate with respect to the vessel.

10. The apparatus according to claim 1 , wherein:
the gate is a first gate;
the first gate is positioned at a first end of the melt zone; and
the apparatus further comprises an additional gate positioned at a second end of the melt zone opposite the first end and configured to contain the material within the melt zone during melting of the material.

11. The apparatus according to claim 1 , further comprising an induction coil surrounding at least part of the melt zone and configured to melt the material.

12. The apparatus according to claim 1 , further comprising a mold configured to receive the material in the molten form from the ejection path of the vessel and to mold the material in the molten form into a molded part.

13. The apparatus according to claim 12 , wherein the molded part is a bulk amorphous alloy part.

14. An apparatus comprising:
a vessel comprising:
a melt zone configured to receive a material; and
an ejection path adjacent the melt zone and extending along a horizontal direction;

a first gate positioned at a first end of the melt zone between the ejection path and the melt zone and configured to move between:
a first position to contain the material within the melt zone during melting of the material; and
a second position to allow movement of the material in a molten form past the first gate and through the ejection path in the horizontal direction; and

a second gate positioned at a second end of the melt zone opposite the first end and configured to contain the material within the melt zone during melting of the material.

15. The apparatus of claim 14 , further comprising a plunger positioned at a second end of the melt zone opposite the first end and configured to move the material in the molten form through the ejection path.

16. The apparatus of claim 14 , further comprising an actuation mechanism coupled to the first gate to selectively move the first gate between the first position and the second position.

17. The apparatus of claim 14 , wherein the second gate is configured to move between:
a third position to contain the material within the melt zone during melting of the material; and
a fourth position to allow movement of a plunger through the melt zone.

18. The apparatus of claim 14 , wherein the first gate is configured to move along a direction that is oblique to the horizontal direction when moving between the first position and the second position.

19. The apparatus of claim 14 , wherein the first and second gates each comprise one or more temperature regulating lines configured to flow a liquid therein to regulate a temperature of the first and second gates during melting of the material.

20. The apparatus of claim 14 , wherein the first gate is a ball valve.

21. The apparatus of claim 14 , wherein the first and the second gates are configured to move substantially simultaneously.

22. An apparatus comprising:
a vessel comprising:
a melt zone configured to receive a material; and
an ejection path adjacent the melt zone and extending along a horizontal direction; and

a gate positioned between the ejection path and the melt zone and configured to move along a direction that is oblique to the horizontal direction to move between:
a first position to contain the material within the melt zone during melting of the material; and
a second position to allow movement of the material in a molten form past the gate and through the ejection path in the horizontal direction.

23. The apparatus of claim 22 , wherein, when moving between the first position and the second position, the gate moves linearly along the direction that is oblique to the horizontal direction.

24. The apparatus of claim 23 , wherein:
the gate is positioned at a first end of the melt zone; and
the apparatus further comprises a plunger positioned at a second end of the melt zone opposite the first end and configured to move the material in the molten form past the gate and through the ejection path.

25. The apparatus of claim 24 , wherein the plunger is further configured to contain the material within the melt zone during melting of the material.

26. The apparatus of claim 23 , further comprising a piston coupled to the gate and configured to move the gate between the first position and the second position.

27. The apparatus of claim 22 , wherein:
the gate is a first gate;
the first gate is positioned at a first end of the melt zone; and
the apparatus further comprises a second gate positioned at a second end of the melt zone opposite the first end.

28. The apparatus of claim 22 , further comprising an induction coil encircling at least part of the melt zone and configured to melt the material.
