MOLD FOR INJECTION MOLDING OF THERMOSETTING MATERIAL

摘要

PROBLEM TO BE SOLVED: To prevent the generation of flash in a molded product caused by an ejector pin. SOLUTION: The through-hole 16 communicating with a cavity 14 is provided to the mold main body 11 of a mold for the injection molding of a thermosetting material so as to be formed into a conical shape so as to expand the opening part 16a on the side of the cavity 14 of the through-hole 16 toward the cavity 14. An ejector pin 19 for discharging a molded product is inserted into the through-hole 16 and the leading end part thereof is formed into an inverted tapered shape inclined toward the inside of the cavity.
