Abstract
In a molding machine, foundry sand thrown into a molding space defined by a pattern plate and flask members is compressed in two steps. Namely, in the first step a lower subsidiary flask is stationary while in the second step the flask is movable. The pattern carrier molding machine comprises a molding base, flask-setting cylinders, a lift-support frame, and a segment-squeeze sand hopper. The auxiliary flask 62 of the compact pattern-plate carrier is installed movably up and down through a plurality of upward oil cylinders 63,63 that are expanded/contracted via special oil cylinders 64,65 operated by outside cylinders 68,69.

An apparatus for molding a mold, comprising
- a pattern plate fixedly and horizontally disposed,
- subsidiary flasks disposed around said pattern plate so as to be moved up and down,
- lift means for moving said subsidiary flask up and down,
- a flask member disposed above said subsidiary flask so as to be moved up and down, and
- compressing means disposed above said flask members, wherein the ends of the compressing members can reach at least a point within said flask member.
A molding machine that consists of a molding base, flask-setting cylinders disposed on both sides of the base, a frame disposed to bridge and support the up-and-down movements of the flask-setting cylinders, and a hopper which is supported by the frame for pressing foundry sand through segmented squeeze feet, the molding machine comprising
- a device for transporting and replacing a carrier on which the pattern plate is to be mounted, and
- a subsidiary flask that has ventholes surrounding said segmented squeeze feet, and that is connected to flask-setting cylinders so as to be movable up and down.
