An optical disk molding apparatus is provided which includes a fixed side mold assembly and a movable side mold assembly. Each mold assembly has a mounting plate, a disk cavity plate, a temperature control liquid passage, and a temperature control liquid sealing device. The temperature control liquid sealing device is comprised of at least one annular aperture formed between the mounting plate and the disk cavity plate around the inner or the outer circumference of the temperature control liquid passage in each of the mold assemblies, a rigid ring fitted within the annular aperture such that there is only a minute clearance between the inner wall of the annular aperture and the rigid ring, and a heat resistant sealing filler charged between the inner wall of the annular aperture and the rigid ring.
