A mold locking device for a molding machine has a toggle assembly, and a transmission member. The toggle assembly has first toggle arms pivoted to a bearing disc of the molding machine, connecting arms pivoted to a movable mold base, second arms pivoted to both the first arms and the connecting arms, and has third arms pivoted to both the second arms and a co-moving disc movable between the bearing disc and the movable mold base. The transmission member has a power source, a connecting member and an elongated screw. The connecting member connects the power source and a nut turnably fitted on the co-moving disc; the screw is passed through the nut for permitting the nut to turn relative to, and move along, the screw. The screw is further connected to the movable mold base such that the movable mold base can be moved between a mold opening position and a closing position by the toggle assembly and the power source.
