PROBLEM TO BE SOLVED: To provide an injection compression molding mold which can prevent the occurrence of galling between a core block and a side surface forming block in forming, and at the same time can prevent the formation of burr, which becomes problems to a molded product. SOLUTION: The injection compression molding mold 11 has a constitution that a core block 18 integrated with a mold body part 15 and side surface forming blocks 29, 30, and 31 are subjected to a relative position change in a form opening and closing direction to the core block 18 are provided on a first mold 12, and the side surface forming blocks 29, 30, and 31 and a second mold 13 are surface-abutted to form volume-changeable cavities C1, and C2. The side surface forming blocks 29 and 30 are pressed toward the core block 18, and at the same time at least one of the inner side surfaces 29b, 30b, and 31b of the side surface forming blocks 29, 30, and 31 and the lateral surface 18b of the core block 18 is hard-faced W.
