ABSTRACT:
A wax injector is used to create the wax mold for use in the investment casting process. The injector utilizes a wax pot to melt and store the molten wax to be injected. A heat exchanger heats the molten wax to its proper injection temperature just prior to injection. A pressure sensor senses when the mold is full of molten wax and shuts the wax valve to ensure proper wax metering. The injector also uses an improved mold clamp to secure and uniformly compress the two halves of the mold. The compressive force is applied via a pneumatically-operated piston attached to the clamp. An internal position sensor measures mold thickness and compression. The mold clamp is enclosed in an air-tight chamber that is evacuated before wax is injected into the mold.
