PURPOSE: To make the plate-shaped body of a molding member thin and to miniaturize the molding member and a molding apparatus as a result by eliminating the necessity for providing a screw hole and the necessity for using a separate seal like an O-ring required in a conventional bolt fixing method. CONSTITUTION: Two molding members comprising two mutually fixed plates 11, 13; 15, 17 are provided to a mold apparatus. Grooves 19 are preliminarily provided to the contact surfaces of one group of plates 13, 15 to form a cooling duct. In order to contract the dimensions of the mold members 4, 6, two plates 11, 13; 15, 17 are mutually fixed by a soldering method. |
