Abstract: A material handling device for transferring a formed good from an injection molding machine includes a pair of spaced tracks. Inner ends of the tracks are positioned below a mold carried by the machine with the track positioned transversely to opening and closing movement of the mold by the machine. On the track is a slidable basket which may be moved from the track inner end to an outer end away from the machine. Basket movement may be effected by activation of a pneumatic drive formed as part of the track and attached to the basket. During forming of a good, the basket is moved under the mold. When forming is complete, the mold opens and the good ejected. The good falls into the basket which has a cushion-like surface to inhibit damage. Opening of the mold starts a first timing period which lapses to activate the pneumatic drive to move the basket and good to the track outer end for good removal. During this first timing period the mold closes to begin a next forming cycle.
