Graphite mold blank clamping and leveling method and graphite mold manufacturing method

The invention is suitable for the technical field of manufacturing of graphite molds, and discloses a graphite mold blank clamping and leveling method and a graphite mold manufacturing method. The graphite mold blank clamping and leveling method comprises the following steps: a clamping step: graphite mold blanks are mounted on fixtures; a detecting step: the fixtures with the graphite mold blanksare put in detecting equipment; and height values of at least three points on the top surfaces of the graphite mold blanks are measured; and a processing step: the fixtures with the graphite mold blanks are taken out from the detecting equipment; and the graphite mold blanks mounted on the fixtures are leveled according to the detecting result in the detecting step. In special production process,the graphite mold blank clamping and leveling method firstly clamps and levels the graphite mold blanks, and then, puts the leveled graphite mold blanks into a milling machine for milling, so that the size precision of finall
