ABSTRACT:
A portable vacuum investment casting apparatus includes a box-like housing having an upper generally flat supporting wall with a vertical conduit terminating in an opening in the top wall. A vacuum conduit is connected to the vertical conduit and terminates in an outer sidewall in large and small conical connectors to receive a conventional shop or household vacuum cleaner hose. A manually adjustable valve is connected in an exhaust pipe from the vacuum conduit for controlling the vacuum level. The apparatus is powered from a conventional household type vacuum cleaner device or similar fan unit which establishes a relatively high air flow with a relatively low vacuum. A small vacuum gauge tube is mounted on the front wall adjacent to the vacuum setting control. The top end is connected to the vertical conduit and the lower end has a supply tube with an adjustable end member to set the initial liquid level. The housing is provided with a power cable connected to a kiln outlet and a vacuum cleaner outlet by corresponding switches. The heated investment is placed on the top wall and molten metal poured into the cavity with the vacuum cleaner source turned on to remove air and gases from within the cavity.
