    摘要: 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.

    摘要: The specification discloses a strike off apparatus for leveling and compacting mounds of sand extending above the upper edges of open-top mold boxes of varying heights carried in succession along a pathway. A pair of pivotally supported rollers extend across the pathway. A sensor determines the height of a sand mound in a mold box before it reaches the rollers. An elevating mechanism responsive to the sensor adjusts the rollers to a height so that they level and compact the sand mound as the mold box is carried thereunder. A control system including electrical and hydraulic circuits is provided for automatically controlling the cyclical operation of the apparatus.

    摘要: In an automatic mold part producing apparatus having a mold chamber which is filled with mold forming material that subsequently is compressed between a pair of opposite end walls, or pattern boards the mold forming material is forced into said mold chamber by means of pressurized air, the pressure of which is gradually or stepwise increased during the chamber filling operation, for the purpose of achieving uniform compactness or density of the mold forming material throughout the height of the mold chamber.
