MOLDING MOLD ASSEMBLY, MOLDING MOLD TO BE USED THEREIN, METHOD FOR MANUFACTURING THE MOLDING MOLD AND METHOD FOR MANUFACTURING PRISM BY USING THE MOLDING MOLD ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To provide a molding mold assembly in which a prism can be manufactured in high manufacturing efficiency.;SOLUTION: The molding mold assembly 10 is provide with a columnar upper mold 11 and a first columnar lower mold 12. One end face of the upper mold 11 is formed into a flat shape. The first lower mold 12 is arranged oppositely to the upper mold 11. The molding mold assembly 10 is used so that a plurality of glass materials 8 are pressed between the upper mold 11 and the first lower mold 12 to form a plurality of triangularly prismatic prisms 9 simultaneously. The first lower mold 12 is provided with a columnar mold main body 14 and a plurality of partition members 15. A linear groove 14a tapered to the depth direction is formed on the opposite end face of the mold main body 14 to the upper mold 11. The groove 14a formed in the mold main body 14 is divided by the plurality of partition members 15 into a plurality of spaces 16 arrayed in the extending direction of the groove 14a for placing the glass materials 8.;COPYRIGHT: (C)2007,JPO&INPIT
