Abstract

Systems and methods are described for forming wax shells for use with electric lighting devices. A template can comprise a sleeve that defines an interior space with a removable core at least partially disposed within the interior space. A modular top can be coupled to the sleeve, depending on the desired upper surface of the wax shell.

First claim

What is claimed is:

1. A device used to form a wax shell for use with an electric lighting device, comprising:
a sleeve configured to define outer dimensions of an interior space;
a removable core configured to be inserted within the interior space to form a space between the sleeve and the core, wherein the space between the sleeve and the core is configured to receive wax to thereby form the wax shell, and wherein the core defines a hollow interior of the wax shell when the core is removed from the wax shell; and
a modular top configured to be coupled to the sleeve, wherein a different top can be swapped out for the modular top to vary an upper surface of the wax shell;
a block disposed between the core and the modular top and configured to form an aperture in an upper surface of the wax shell.

2. The device of claim 1 , further comprising an insert configured to vary an outer surface of the wax shell.

3. The device of claim 1 , further comprising a top having a gate and a vent, wherein a hot wax can be inserted into the interior space via the gate.

4. The device of claim 3 , wherein an excess wax can exit the interior space via the vent.

5. The device of claim 1 , further comprising an ejector configured to eject the wax shell from the core once the wax shell is formed by applying force to the block.

6. The device of claim 1 , wherein at least one of the core and sleeve is configured to receive a coolant.

7. The device of claim 1 , wherein each of the core and sleeve is configured to receive a coolant.

8. The device of claim 6 , wherein the coolant comprises water.

9. The device of claim 6 , wherein at least one of the core and sleeve comprises a heat exchange that effects a heat exchange between the wax shell and the coolant.

10. The device of claim 1 , wherein the core further comprises a keyway, such that the wax shell comprises a projection configured to guide insertion of a plastic core into the wax shell.

11. A method for forming wax shells, comprising:
providing a device having a sleeve that defines a hollow interior space, a core disposed within the interior space and that further defines the hollow interior space as the void between the sleeve and core, a modular top configured to be coupled to the sleeve, and a cap having a gate;
inserting the core within the interior space;
providing a block disposed between the core and the modular top, and configured to form an aperture in an upper surface of the wax shell; and
feeding wax into the void of the interior space via the gate to form a wax shell with an aperture in an upper surface of the wax shell and having a hollow interior.

12. The method of claim 11 , wherein the cap further comprises a vent through which excess wax can exit the interior space.

13. The method of claim 11 , further comprising providing a manifold having at least one conduit, and wherein the step of feeding the wax into the interior space further comprises feeding the wax through the at least one conduit into the interior space via the gate.

14. The method of claim 13 , wherein the wax is pressurized at a point when the wax enters the interior space.

15. The method of claim 13 , wherein the manifold further comprises at least one guide configured to align the conduit with the gate.

16. The method of claim 13 , further comprising automatically ejecting the wax shell from the interior space and disengaging the core from the device after the wax hardens.

17. The method of claim 13 , further comprising feeding a cooling fluid into at least one of the core and sleeve to cause heat exchange between the wax and the at least one of the core and sleeve.

18. The method of claim 13 , wherein the core further comprises a keyway.
