Foundry molding machine

A foundry molding machine comprising two mold units, each of the mold units being provided with a respective match plate support and a sand filling- and compaction station for the separate simultaneous fabrication of two foundry mold parts, one of the mold parts defining a mold-lower part and the other mold part a mold-upper part, each of the mold units comprising a respective pivotal device possessing pivotal arms which are pivotable about substantially vertical axes in a respective substantially horizontal plane, said pivotal arms being provided with mold frame holders for supporing mold frames which can be rotated from the sand filling- and compaction station while rotating each mold frame containing the mold-lower part through an angle of about 180.degree. about a horizontal shaft into a position where both mold parts are in superimposed position at an assembly station where both mold parts are deposited upon one another onto a conveyor device, the improvement comprising:

• each pivotal device comprising at least three substantially uniformly offset pivotal arms carrying the mold frames in the mold frame holders, and means for rotating each of the mold frames of both pivotal devices through an angle of about 180.degree. about a respective substantially horizontal axis and means for individually vertically displacing each of the mold frames.
