Abstract:
Provided is a parting lock device for an injection molding mold in which a state of connection between a base holder and a lock member can be released even while a lock bar is inserted into the lock member, and in which movement of the lock bar is stabilized. A lock bar (16) has a thick part (16a) and a thin part (16b). In a first state in which the thick part (16a) is positioned between an engagement element (11) and an inner surface of a bar insertion hole (9) and a third state in which the lock bar (16) has been pulled out from the lock member (8), the engagement element (11) moves to a first engagement element passage (5) or a second engagement element passage (6) to release a state of connection of the lock member (8) with respect to a base holder (2). In a second state in which the thin part (16b) is positioned between the engagement element (11) and the inner surface of the bar insertion hole (9), the engagement element (11) engages with an engagement concave part (7) to maintain the state of connection of the lock member (8) with respect to the base holder (2).
