ABSTRACT:
In a machine for the automatic production of flaskless foundry molds by a blow-squeeze method between opposed pattern plates in an opening in a slider which then moves to carry the newly formed mold clear of its point of production, to a point where it is ejected, the slider moves vertically and the point of ejection is vertically below the point of production. Preferably both pattern plates are actuated by a single ram assembly which lies to one side of the slider, being connected to the pattern plate on the other side through tie-rods.
