In practice, the operation of the aluminum honeycomb core hot press of the present invention is as follows. The aluminum honeycomb core is pushed into the space between the adjacent hot pressing plates 21 from the left side of the hot pressing cavity, and one aluminum honeycomb core is positioned between a pair of adjacent hot pressing plates 21. The bottom of the aluminum honeycomb core is pressed on the movable plate 40, the top of the aluminum honeycomb core leans against the hot pressing plate, and a gap is formed between the top of the aluminum honeycomb core and the top of the hot pressing cavity. The pushing device outside the frame 10, such as the cylinder, the oil cylinder, and the screw rod mechanism, acts on the push rod 200 of the hot pressing head 20 to drive the hot pressing head to move backward, the bottom surface of the hot pressing head slides on the fixing plate 11, after the hot pressing head moves backward for a certain distance, the bottom surface of the hot pressing head contacts with the friction wheel 51, the hot pressing head moving backward drives the friction wheel to rotate, the friction wheel drives the driving shaft 522 to rotate, the driving gear 5261 rotates, the transfer gear 5262 rotates, the internal gear 5263 rotates, and the protrusion assembly 524 rotates.
