ABSTRACT:
An ejector blade for ejecting parts from injection molds. The ejector blade has an elongate shank portion with a slotted end therein, a flat blade portion having an end shaped to be engaged within the slot, and apertures through the engaged ends in registration with one another with a pin engaged in the apertures to join the shank and blade portions releasably so that different blade portions can be mounted on the shank portion. The pin is a slotted roll pin and the aperture in the shank portion is larger in diameter than the aperture in the blade portion in order to permit some movement between the blade and shank portions to accommodate variations in a mold in which the ejector blade is used.
