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 an interior space; a core configured to be inserted within the interior space; 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.

2 . The device of claim 1 , wherein the volume between the sleeve and the core is configured to receive wax to thereby form the wax shell.

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

4 . 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.

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

6 . The device of claim 1 , further comprising an ejector configured to eject the core and wax shell once formed.

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

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

9 . The device of claim 7 , wherein the coolant comprises water.

10 . The device of claim 7 , 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.

11 . 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.

12 . A method for forming wax shells, comprising:
providing a device having a sleeve that defines an interior space, a core disposed within the interior space, a modular top configured to be coupled to the sleeve, and a cap having a gate; and feeding wax into the interior space via the gate.

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

14 . The method of claim 12 , 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.

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

16 . The method of claim 14 , wherein the manifold further comprises at least one guide configured to align the conduit with the gate.

17 . The method of claim 14 , further comprising automatically ejecting the wax and core from the device after the wax hardens.

18 . The method of claim 14 , 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.

19 . The method of claim 14 , wherein the core further comprises a keyway.
