Claim 7:
8. The alumina ceramic integrated hot press molding machine according to claim 1, wherein a space between a transmission shaft of the stirring device and a slurry bucket is filled with a packing material, a gland of the stirring device is located at a bottom of an oil bath box, internal threads are disposed inside the gland, the gland is in threaded connection with a convex head of the slurry bucket, and the gland is in clearance fit with an oil outlet of the oil bath box; a pressing sleeve is configured to tightly press the packing material as the gland rotates along external threads of the convex head of the slurry bucket, and thus, leakage of the slurry is avoided by virtue of a labyrinth effect of the packing material; the gland tightly presses rubber sealing rings located on a slurry bucket base and an oil bath box base at the same time, and thus, leakage of the oil is avoided; and furthermore, transmission efficiency of the transmission shaft is higher under the cooperation of multiple sets of bearings.
