Abstract
An articulated core blade assembly provides improved release of undercuts and similar structures in mold cavities. The articulated core blade assembly includes a retainer secured to an ejector plate, a lifter which moves the product and releases the undercut and a pivot arm which couples the lifter to the retainer. A first knuckle joint couples one end of the pivot arm to the retainer and a second knuckle joint couples the other end of the pivot arm to the lifter. The knuckle joints provide limited pivoting motion about parallel, spaced-apart axes. The articulated core blade assembly may be utilized in a broad range of injection molding machines utilizing plastics, metals and other injection molded materials.
