A molding die is equipped with a lower holder (11), a middle holder (12), an upper holder (13), a locking member (4), an upper link bar (3), a lower link bar (2), a restricting member (5), and a driving unit (6). The locking member is held by the middle holder so that movement in the die-opening and -closing direction is restricted and movement in the die-separating plane direction is possible. There is a first holding groove (31) into which the locking member can fit in the closed die position. The lower link bar has a second holding groove (21) into which the locking member can fit, and a releasing part (22), which, when the locking member that has been fit into the first holding groove of the upper link bar enters the releasing part, makes the locking member releasable from the first holding groove. The restricting member is able to move between a restricting position in which the fitting of the locking member into the second holding groove is prohibited and a free position in which the fitting of the locking member into the second holding groove is allowed. |
