Wax pressing device for preventing ceramic core from being fractured during wax pressing and using method of wax pressing device

The invention belongs to the technical field of casting, and relates to a wax pressing device capable of preventing a ceramic core from being broken during wax pressing and a using method of the wax pressing device. The top of the bottom plate is provided with a mold pressing system used for carrying out wax pressing on a ceramic core, a positioning system used for positioning and fixing the head and the bottom of the ceramic core and a coating system used for coating two side walls of the ceramic core with model wax, and the bottom plate is provided with a guide rail used for driving the coating system to move. According to the ceramic core wax pressing device, before wax pressing is conducted on a ceramic core, the coating system is adopted to coat model wax on the surface of the ceramic core, the wax material impact force borne by the ceramic core during wax pressing is reduced, the wax pressing efficiency is improved, and the wax pressing quality is improved. And the shrinkage stress after wax injection i
