Abstract
In an apparatus for producing casting mould parts by compacting sand or other like material between a vertical squeeze plate ( ) and a vertical swingable plate ( ) in a squeeze chamber ( ), wherein the swingable plate ( ) swings away after the compaction to allow passage of the mould part from squeeze chamber ( ) by further forward movement of the squeeze plate ( ) and the swingable plate is journaled on a front yoke ( ) mounted on guide columns ( ) for movement relative to the squeeze chamber ( ), a pull yoke ( ) is placed behind the squeeze chamber ( ) and connected to the guide columns ( ). At least two of the guide columns ( ) are journalled in a number of guides ( ) connected to a fixed part of the apparatus close to the position of the front yoke ( ) in the compacting position and the pull yoke ( ) is provided with at least one guide ( ) journaled on guide columns ( ) connected to fixed parts of the apparatus. By this construction the rigidity of the frame structure consisting of front yoke ( ), guide columns ( ) and pull yoke ( ) is increased by the guidance of the pull yoke which prevents movements in a plane perpendicular to the intended movement of the frame structure.
