Abstract: A ceramic molding machine is used for hot molding ceramic parts under low pressures for small part production molding and includes a heated tank that is generally conical in shape and has an internal mixer that is driven from the exterior of the tank through a slip clutch arrangement to avoid overloading of the drive motor. The conical tank insures that the ceramic slurry will flow toward the bottom outlet from the tank and also permit use of small amounts of slurry for small runs of parts if the material is expensive. The mixer blade or paddle is driven from the bottom and removable from the top and thus the tank can easily be serviced. Additionally, air pressure is utilized for holding the molds in position over the feeder pipe and also for transferring the slurry to the mold in a timed sequence that can be controlled to provide the desired time for filling of the mold.

Abstract: A control for controlling the level in one of two tanks used in a ceramic hot molding machine which requires transfer of a ceramic slurry from one tank to the other in a continuous molding process. More particularly the present invention relates to an apparatus which automatically shuts off the transfer process when the working tank is filled a predetermined amount.
