Title: SAND MOULDING MACHINE AND METHOD OF PRODUCING SAND MOULD PARTS
Abstract:
The moulding machine includes a moulding chamber having at least one chamber end wall (8) 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 (91, 92, 119). 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.
