Abstract: In a mold producing foundry machine generally according to the “Disamatic®”-principle a method of compensating for relatively slowly varying compaction properties of the mold particle material without compromising the geometrical requirements for repeatedly fixed placements of the pattern plates defining the mold chamber before the shot, comprises previous establishment of a beneficial set of starting parameters for shot and pressing of the mold to a fix terminating compaction force. The percentual volume reduction from the fixed starting volume to the terminating volume of the compacted mold—yielding the mold compressibility—is compared to the previously established beneficial reference value and the succeeding shots are adaptively controlled to compensate for the realised offset in compressibility by especially regulating the shot pressure, duration and fluidization parameters in a cyclic sequence securing steady reduction of the offset value to be within acceptable margins.

Abstract: Moulding machine (1) for the moulding of sand moulds (4, 5) by blowing sand in through slitshaped openings (14, 15) extending across each side plate (16, 17) of a moulding box (6, 7). Into the boxes (6, 7) extend moulding patterns (12, 13). At least one of the end parts (18, 19) of the slitshaped openings has a greater width than the central part (20, 21) thereof. When the sand is blown in through the openings (14, 15) a greater amount of sand is achieved at the peripheral region of the boxes (6, 7) than when the end parts has no greater width than the central part of the opening. Consequently, by the present solution is achieved a greater hardness of the squeezed sand moulds at the peripheral region than by the prior art solutions.
