The moulding machine includes a moulding chamber having at least one chamber end wall provided with a pattern plate adapted to form a pattern in a mould part and associated with a reference pattern block positioned in fixed relationship to a pattern of said pattern plate and adapted to form a reference pattern in an external face of a mould part. A detection system detects the position of a pattern face of the reference pattern of the sand mould part. A transverse and/or a rotational compaction position of a pattern plate is adjustable by means of at least one actuator. Said actuators are controlled by means of a control system on the basis of successive position detections performed by the detection system of pattern faces of reference patterns of compacted sand mould parts traveling along said path of travel.

Sand moulding machine and method of producing sand mould parts

A method and system for indexing moulds using a flaskless moulding machine and a mould conveyor are provided. The method comprises: (i) forming one or more moulds, each of the one or more moulds being added to the mould string while the mould string is stationary by being brought into contact with the mould string. Once the one or more moulds has been added to the mould string, the method continues (ii) by advancing the mould string, in a single continuous motion, a distance corresponding to the sum of the thicknesses of the one or more moulds, wherein (1) the moulding machine assists the mould conveyor in advancing the mould string during a first part of the distance, and (2) the mould conveyor advances the mould string a second part of the distance, corresponding to the remainder of the distance, without assistance from the moulding machine.

Method and system for indexing moulds

The moulding machine includes a moulding chamber having at least one chamber end wall () provided with a pattern plate adapted to form a pattern in a mould part and associated with a reference pattern block positioned in fixed relationship to a pattern of said pattern plate and adapted to form a reference pattern in an external face of a mould part. A detection system detects the position of a pattern face of the reference pattern of the sand mould part. A transverse and/or a rotational compaction position of a pattern plate is adjustable by means of at least one actuator (). Said actuators are controlled by means of a control system on the basis of successive position detections performed by the detection system of pattern faces of reference patterns of compacted sand mould parts travelling along said path of travel.

The moulding machine includes a moulding chamber having at least one chamber end wall provided with a pattern plate adapted to form a pattern in a mould part and associated with a reference pattern block positioned in fixed relationship to a pattern of said pattern plate and adapted to form a reference pattern in an external face of a mould part. The reference pattern block includes a face having a tangent varying in a longitudinal direction of the moulding chamber and being adapted to form a corresponding reference pattern in the sand mould part. A non-contact detection system () detects the position of a number of different points (P, P) distributed over the pattern face of the reference pattern in the longitudinal direction of the sand mould part, and the tangent (T, T) in the longitudinal direction of the sand mould part is different between at least two of said points.

Molding chamber arrangement () for a mold-string plant comprising a molding chamber () formed by a chamber bottom (), a chamber ceiling () provided with one or more sand filling openings () communicating with a sand-feed system (), two chamber side walls (), a pressure plate () provided with an exchangeable pressure pattern plate having a pressure pattern () and being connected to a movement mechanism (), a swingable plate () provided with an exchangeable swing pattern plate having a swing pattern () and being mounted for translational and swinging movement in order to open and close the molding chamber (), allowing the pressure plate () to expel the produced molds, and further comprising means () for vertically moving the chamber ceiling () and sand-feed system () in unison, or the chamber bottom (), or both, relative to the remainder of the molding chamber arrangement (), thereby changing the height of the molding chamber. By this arrangement, the flexibility of the size of the produced molds, especially the heights of the produced molds, can be adjusted without changing the geometry of the sand feed system above the molding chamber in a time-saving manner.
