The invention discloses a hoisting mechanism of a die block carrier. The hoisting mechanism comprises a connection frame, a tray frame, a hoisting cylinder, rocker welding bodies, push rod assemblies and pull rod assemblies. Push rod upper supports are symmetrically arranged on the inner side of the connection frame. Guide rails are symmetrically arranged on the two sides of the connection frame. A middle vertical plate and a small vertical plate which are parallel are symmetrically arranged on the two sides of the inner side of the tray frame. The upper ends of the push rod assemblies are connected with the push rod upper supports in a hinged manner. The upper ends of the rock welding bodies are connected with the lower ends of the push rod assemblies in a hinged manner. The rear ends of the rocker welding bodies are connected with the middle vertical plate and the small vertical plate in a hinged manner. Two front legs are symmetrically arranged at the front end of the tray frame. The front ends of the front legs are connected with the upper ends of front wheel supports in a hinged manner. The rear ends of the pull rods assemblies are connected with the front ends of the rocker welding bodies in a hinged manner. The front wheel supports and front wheel assemblies are connected in a hinged manner. The lower end of the hoisting cylinder is connected with the connection frame, and the upper end of the hoisting cylinder is connected with the tray frame. The tray frame can rise and fall through stretching and retreating of a piston rod of the hoisting cylinder, the structure is simple, and maintenance is convenient.
