Abstract

A mold transfer assembly includes a transfer housing providing an interior defined by one or more sidewalls and a top. The transfer housing is sized to receive and encapsulate a mold as the mold is moved between a furnace and a thermal heat sink. An arm is coupled to the transfer housing to move the transfer housing and the mold encapsulated within the transfer housing between the furnace and a thermal heat sink. The transfer housing exhibits one or more thermal properties to control a thermal profile of the mold.

First claim

What is claimed is:

1. A mold transfer assembly, comprising:
a transfer housing providing an interior defined by one or more sidewalls and a top, the transfer housing being sized to receive and encapsulate a mold as the mold is moved between a furnace and a thermal heat sink, the transfer housing comprising:
a first cylinder defining a first lateral opening sized to receive the mold; and
a second cylinder concentric with the first cylinder and defining a second lateral opening sized to receive the mold, wherein at least one of the first or second cylinders is rotatable with respect to the other; and

an arm coupled to the transfer housing to move the transfer housing and the mold encapsulated within the transfer housing between the furnace and a thermal heat sink, wherein the transfer housing exhibits one or more thermal properties to control a thermal profile of the mold.

2. The mold transfer assembly of claim 1 , further comprising an insulation enclosure sized to receive the mold.

3. The mold transfer assembly of claim 2 , wherein the insulation enclosure is further sized to receive the mold while encapsulated by the transfer housing.

4. The mold transfer assembly of claim 1 , further comprising one or more internal features defined on one or more inner surfaces of the transfer housing to maintain the mold at least one of radially and axially offset from the transfer housing.

5. The mold transfer assembly of claim 1 ,
wherein at least one of the first or second cylinders is rotatable with respect to the other to transition the transfer housing between an open configuration, where the first and second openings are aligned with one another and the mold is able to be received into the first and second cylinders via the first and second openings, and a closed configuration, where the first and second openings are offset from one another and the mold is encapsulated within the first and second cylinders.

6. The mold transfer assembly of claim 1 , wherein the one or more thermal transfer properties vary along a height of the transfer housing.

7. The mold transfer assembly of claim 1 , wherein the one or more thermal properties vary about a circumference of the transfer housing.

8. A method, comprising:
exposing a mold in a furnace;
extending a mold transfer assembly toward the mold, the mold transfer assembly including a transfer housing and an arm coupled to the transfer housing, wherein the transfer housing is sized to receive the mold and provides an interior defined by one or more sidewalls and a top, the transfer housing further comprising a first cylinder defining a first lateral opening sized to receive the mold, and a second cylinder concentric with the first cylinder and defining a second lateral opening sized to receive the mold, wherein at least one of the first or second cylinders is rotatable with respect to the other;
encapsulating the mold within the interior of the transfer housing;
moving the mold encapsulated within the transfer housing from the furnace to a thermal heat sink with the mold transfer assembly; and
controlling a thermal profile of the mold with one or more thermal properties of the transfer housing.

9. The method of claim 8 , further comprising:
releasing the mold from the transfer housing;
retracting the mold transfer assembly from the mold; and
lowering an insulation enclosure over the mold.

10. The method of claim 8 , further comprising:
detaching the arm from the transfer housing; and
retracting the arm from the transfer housing.

11. The method of claim 8 , further comprising lowering an insulation enclosure over the transfer housing and the mold encapsulated within the transfer housing.

12. The method of claim 8 , further comprising varying the one or more thermal properties of the transfer housing along at least one of a height of the transfer housing and a circumference of the transfer housing.

13. The method of claim 8 , further comprising maintaining the mold at least one of radially and axially offset from the transfer housing with one or more internal features defined on one or more inner surfaces of the transfer housing.

14. The method of claim 8 , wherein encapsulating the mold within the interior of the transfer housing comprises:
moving at least one of the first and second cylinders with respect to the other to transition the transfer housing to an open configuration, where the mold is able to be received into the first and second cylinders via the first and second openings;
receiving the mold within the interior of the transfer housing; and
moving at least one of the first and second cylinders with respect to the other to transition the transfer housing to a closed configuration, where the mold is encapsulated within the first and second cylinders.

15. The method of claim 8 , further comprising one or more thermal elements coupled to or supported by the transfer housing, and wherein controlling the thermal profile of the mold comprises selectively heating the mold with the one or more thermal elements.

16. The method of claim 8 , further comprising one or more thermal conduits coupled to or supported by the transfer housing, and wherein controlling the thermal profile of the mold comprises:
circulating a thermal fluid through the one or more thermal conduits; and
actively heating the mold with the thermal fluid.
