PROBLEM TO BE SOLVED: To miniaturize a servomotor for opening/closing a mold and to smooth the movement of the output side of a toggle link mechanism in a molding machine using the toggle link mechanism. SOLUTION: In the toggle link mechanism including a link B with its one end side held rotatably by a tailstock, a link A with its one end side held rotatably by a movable die plate and with its other end side bonded relatively rotatably to the other end side of the link B, and a link C with its one end side bonded rotatably to a cross head and with its other end side bonded relatively rotatably to the swelling-out part of the link B, when the rotation center of the rotation bonding part between the link B and the tailstock is O1, the rotation center of the rotation bonding part between the link B and the link A is O2, and the rotation center of the rotation bonding part between the link B and the link C is O3, an angleθformed by a line segment connecting O1 and O2 and a line segment connecting O2 and O3 is set to be larger than 90°.
