[0002] Wax press is a device used for wax molding of small and medium-sized complex, high-quality, high-precision precision castings. It is an indispensable equipment in the production process of precision castings. It is mainly used to hydraulically press the molten wax into wax products of various shapes. Its product structure mainly includes wax melting pot, hydraulic system, mold, table and control system.

[0003] At present, the existing wax pressing machines lack a mechanism for cutting and crushing solid wax, resulting in that when larger blocks of solid wax are put into the wax melting pot, the wax liquid in the wax melting pot cannot be quickly melted and mixed, resulting in slow melting of the material. In addition, the wax melting pot of the existing wax pressing machines lacks a mechanism for cleaning the pot wall, resulting in the residual wax liquid easily adhering to the pot wall due to solidification, causing pollution to the environment in the pot and affecting subsequent use. In view of this, the utility model proposes a casting mold wax pressing machine. Utility Model Content
