PROBLEM TO BE SOLVED: To provide a venting member for an injection molding die for a product of a synthetic resin material, which makes it possible to efficiently discharge gas in a cavity outside the die even at a position in the cavity other than a parting surface of the die, and has excellent maintainability.SOLUTION: A venting member for an injection molding die 1 includes: a columnar solid nest 2 that becomes a center; and hollow nests 3 and 4 that are decomposably disposed outside the solid nest 2 and respectively form at least one or more external layers. A fine slit 8 is formed at a boundary between an outer peripheral surface of each of the nests and an external surface thereof. The fine slit is continuous with a space communicating with an outside part of the die formed between a mounting groove B2 and each nest. |
