ABSTRACT:
A cyclicly-operable molding machine for producing and assembling cope and drag mold parts. A rotary turntable which supports four pairs of flask sections is repeatedly indexed to move the pairs repeatedly and successively in a circular path through four stations, namely, (1) a working station where the flask sections are variously and automatically handled and in cooperation with a pattern-carrying match plate are filled and compacted with foundry sand so as to produce the two mold parts, (2) a core-setting station where, if required or desired, a core may be applied to one of the formed mold parts, (3) a stripping station wherein the flask sections are again variously handled to strip the sections from the mold parts and the latter are assembled and then deposited on a bottom board which is ejected from the machine, and (4) an idle or dwell station where an empty pair of flask sections awaits handling of a preceding pair of flask sections at the working station before being returned to such station for refilling thereof at the commencement of the next machine cycle.
