Abstract

An exemplary forming assembly includes a mold having a cavity to form a component, and an insert having first, second, and third regions. The first region provides a first passageway opening in the component. The second region provides a second passageway opening in the component. The third region provides a passageway in the component. The insert is rotatable from a first position within the passageway to a second position outside the passageway. An exemplary component forming method includes positioning a material around an insert, curing the material to provide a component, and rotating the insert relative to the component from a first position where at least some of the insert is received within a passageway of the component to a second position where the entire insert is outside the passageway.

First claim

What is claimed is:

1. A forming assembly, comprising:
a mold having a cavity to form a component; and
an insert having a first region to provide a first passageway opening in the component, a second region to provide a second passageway opening in the component, and a third region to provide a passageway in the component, the insert rotatable from a first position within the passageway to a second position outside the passageway.

2. The forming assembly of claim 1 , wherein the insert is rotatable from the first position to the second position through the first passageway opening.

3. The forming assembly of claim 1 , wherein the third region extends from the first region to the second region.

4. The forming assembly of claim 3 , wherein the third region has an arc-shaped profile.

5. The forming assembly of claim 3 , wherein the first region has a cross-sectional area that is greater than a cross-sectional area of the second region and the third region of the insert decreasingly tapers from the first region to the second region.

6. The forming assembly of claim 1 , wherein the passageway is a coolant passageway.

7. The forming assembly of claim 1 , wherein the first region is a first contact face of the insert that is configured to directly contact the mold, and the second region is a second contact face of the insert that is configured to directly contact the mold.

8. The forming assembly of claim 1 , wherein the component is an engine block and the insert is positioned between a first cylinder and a second cylinder of the engine block when the insert is in the first position.

9. The forming assembly of claim 8 , wherein the first cylinder, the second cylinder, the first opening, and the second opening, all open to a common surface of the engine block.

10. The forming assembly of claim 1 , wherein the component is aluminum and the insert comprises a material other than aluminum.

11. A component forming method, comprising:
positioning a material around an insert;
curing the material to provide a component; and
rotating the insert relative to the component from a first position where at least some of the insert is received within a passageway of the component to a second position where the entire insert is outside the passageway.

12. The method of claim 11 , wherein the insert is within a mold cavity during the surrounding.

13. The method of claim 11 , wherein the passageway extends from a first opening to a second opening, and the insert is moved through the first opening during the rotating.

14. The method of claim 13 , wherein the first opening has a cross-sectional area that is greater than a cross-sectional area of the second opening, and the passageway decreasingly tapers from the first opening to the second opening.

15. The method of claim 13 , wherein the passageway is distributed annularly from the first opening to the second opening.

16. The method of claim 11 , further comprising rotating the insert relative to the component no more than 180 degrees about an axis to move the insert from the first position to the second position.

17. The method of claim 11 , further comprising positioning a first region of the insert against a mold during the curing to provide the first opening, and positioning a second region of the insert against the mold during the curing to provide the second opening.

18. The method of claim 11 , wherein the passageway has a rectangular cross-sectional profile.

19. The method of claim 11 , further comprising communicating a coolant through the passageway when the insert is in the second position, and cooling the component using the coolant, wherein the component is an engine block.

20. The method of claim 11 , further comprising shrinking the material away from the insert during the curing.
