Abrégé

Methods and devices for producing a casting mold for sand casting are disclosed. In one embodiment, a method for producing a compacted mold for casting molten material may include positioning a model or pattern in a flask; filling the flask with compactable sand; and compacting the compactable sand around the model or pattern so as to form a compacted mold or compacted mold component suitable for casting. The compacting of the molding sand takes place in zones or regions smaller than a lateral extension of the flask based on a contour or a dimension of the model or pattern.

Abrégé

The aim of the invention is to produce improved moulds for the casting of metals without increasing the complexity of production. By "improved" it is meant that the mould, consisting of the mould material, permanently has a surface of uniform hardness, even in the event of a change or variation in the quality of at least one of a plurality of properties of the mould material. Also disclosed is the production of a mould material mould for a cast having minimum strength for the casting of metals. A granular mould substance is poured into a mould box (40) as a mould material (41). The mould substance (41) is compacted in the mould box (40) in a mould system above a pattern (44) which stands on a pattern plate (46). In a first step, the mould box (40) is moved by a press device (1) across a first distance to stop against a frame (13) of a press head (10). In a second step, the pattern plate (46) is moved by the press device (1) across a second distance (s1, s2) into an end position in order to harden or compact (create) the mould material mould. A length of the second distance (s1,s2) is preferably automatically changed in accordance with the mould material, or the second distance (s1,s2) is changed as a result of a change in at least one property of the non-compacted mould material (41) and in accordance with a force determined at the end of a previous hardening or compacting of the mould material of the previous mould (100,102;102'). The proposed mould machine operates in the manner of a hardness control (strength control) of the mould material (41) in the compacted mould.

Abrégé

The invention relates to a method for producing a casting mold for sand casting, wherein a model is positioned in a molding flask and the molding flask is filled with molding sand (green or wet sand - sand, bentonite, and water) and wherein the molding sand is compressed around the model in order to form a stable mold suitable for casting, is characterized in that the compression of the molding sand occurs in certain zones or regions, with consideration of the contour and/or the dimensions of the model. A corresponding device for using the method comprises a compression unit having a compression head having a plurality of compression cylinders.
