Abstract
A foundry machine for forming molds or cores from a molding material such as sand provides completely automated loading and unloading of tooling elements (24). The tooling elements (24) comprising a sand magazine (36), blow plate (34), combined gassing manifold and top ejector unit (32), upper mold box (30), lower mold box (28) and bottom stool (26) are automatically transferred, in stacked, separable relationship, by tracks (40) to a vertically displaceable, work table. Vertical displacement of the work table (42) sequentially elevates the tooling elements (24) to positions within a mainframe (10) where automatically operated clamping means secure the appropriate tooling elements (24) in respective operating positions. The gassing manifols (32) includes an ejector pin assembly (274, 280) mounted therewithin.
