  • Patent number: 4808102
    Abstract: An apparatus for handling and transferring an article formed in an injection molding machine includes a pair of spaced tracks. Inner ends of these tracks are positioned below a mold carried by the machine with the tracks positioned transversely to opening and closing movement of the mold by the machine. On these tracks is a slideable basket which may be moved from the track inner end to an outer end away from the machine. The basket is operatively connected to a pneumatic drive operated by a controller. During forming of the article, the basket moves under the mold. When forming is complete, the mold opens and the article ejected. The article falls into the basket which has a cushioney surface to inhibit damage. Opening of the mold is sensed by the controller to activate the pneumatic drive and move the basket and article to the track outer end where the article is removed. Concurrently the mold closes to begin a further forming cycle.

  • Patent number: 4719059
    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.
