PROBLEM TO BE SOLVED: To provide a stamper press structure for a mask molding die device for preventing the generation of defects such as the floating of a stamper or a stamper press ring and others, and blowing releasing air effectively between a disk molded product and the stamper at the time of flowing out the release air. SOLUTION: In a structure in which a stamper press ring 30 having a stamper press section 32 for pressing a surface outer peripheral section of a stamper 20 disposed on a mirror plate 21 is provided on the tip of an inner ring section 31 specifying an outer peripheral end section of a cavity 19 for molding a disk molded product D and releasing air A is blown out of a small space S between the stamper press section 32 of the stamper press ring and the stamper surface, an outer peripheral protrusion 33 being in contact with a surface outer peripheral edge 20A is formed on the outer peripheral side of the stamper press section 32 of the stamper press ring, and an outflow section 35 for release air is formed between the stamper press section 32 and the outer peripheral protrusion 33. |
