MOLD FOR INJECTION MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a mold for injection molding which uniformly cools a molded article to thereby reduce temperature difference in the molded article to <1°C in a short period of cooling time. SOLUTION: An interval between a mold base body surface and a nesting surface is supported by a plurality of column supports (7) and the interval is used as a heating medium flow passage (8) to thereby increase the surface area of the heating medium flow passage compared to that of conventional piping structure.
