Abstract
A lever-type mold ejection mechanism is arranged on a platen of a mold in the injection molding machine. The lever-type ejection mechanism includes a base body arranged on the platen; an actuating cylinder having a motion shaft; a link rod having a first end and a second end opposite to each other, wherein the first end is pivotally disposed on the base body through a first pivot axis, and the second end is pivotally disposed on an end of the motion shaft of the actuating cylinder through a second pivot axis, and the link rod has a movable ejector pin at its bottom surface adjacent to the first end; and a ejector rod resisting between the ejector pin and the mold. The actuating cylinder is operated to push the mold through the link rod in a lever manner so as to obtain enough pushing force.
