1.

Answer» The correct answer is (d) Ejector PINS For explanation I would say: The ejector pins, which move through the moving die to free the CASTING from the ejector die. The number of ejector pins should be sufficient so as to remove the HOT casting WITHOUT any DISTORTION. And the position of ejector pins should be like so that the pins marks remain on the casting are not objectionable.
