For the production of horizontally divided flaskless foundry molds a mold making plant is employed consisting of a vacuum mold blowing machine, joined with a casting and cooling line and a shake out station. The vacuum mold blowing machine is provide with a pattern plate swapping device and designed in the form of a single station mold making maching, in which drags and copes of a mold are produced alternately. The single mold flask is part of the mold making machine and has means for stripping it from a drag or cope before removal of the same from the machine. This makes it possible to have one core insertion station with space for a plurality of drag without having more than one machine flask.
