What is described is a process for producing an article for use in the foundry industry selected from molds, cores, feeder elements and molding material mixtures, and includes the following steps: (S1) producing or providing a binder system with the following components in three spatially separate vessels: a component (A) particulate amorphous silicon dioxide, a first liquid component (B) waterglass, and a second liquid component (C) aluminate ions dissolved in an aqueous phase, (S2) contacting a mold base material (D) and constituents of all the components (A), (B) and (C) of the binder system in predetermined ratios in one or more steps, so as to result in a molding material mixture in which the aluminate ions and the particulate amorphous silicon dioxide are mixed wholly or partly into the waterglass, wherein steps (S1) and (S2) are conducted in a facility for producing molding material mixtures. Also described are a corresponding molding material mixture and apparatuses and uses.

A mold device includes a frame that is a vertical wall having a first surface that is a vertical surface to which a holding mechanism is mounted and supported only by the first surface. A fixed mold base supporting a fixed mold, one surface thereof fixed to the first surface of the frame, and a mobile mold base supporting a mobile mold, the mobile mold base held by the holding mechanism so that the mobile mold base moves closer to and away from the fixed mold base. The holding mechanism includes a rail fixed to the first surface, and a guide fit on the rail in such a way that the guide moves on the rail while the guide is fixed to the mobile mold base. The mobile mold base is supported by the holding means without using a tie bar, and cantilevered on the first surface via the holding mechanism.
