GRAPHITE MOLD FOR INJECTION MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a graphite mold for injection molding enhanced in durability by reinforcing the region forming the deep part of the molding recessed part corresponding to the projected part of a synthetic resin molded object. SOLUTION: The graphite mold 9 has first and second molding recessed parts 18 and 19 corresponding to the projected parts of the synthetic resin molded object having the first and second projected parts. The graphite mold 9 has a graphite mold main body 26 having first and second hollow thin-walled projected parts 24 and 25 for forming the deep parts (s) of the first and second molding recessed parts 18 and 29 by an internal space and the first and second backup bodies 27 and 28 brought into close contact with the outer surfaces of the first and second hollow thin-walled projected parts 24 and 25.
