发明名称 A method for compacting moulding sand
摘要 A method for compacting molding sand in a molding box in which a model is present, which model is embedded in molding sand. The molding box is vibrated by means of imbalance weights, which are each to be rotated about an axis of rotation during operation. At least four imbalance weights being rotatable about parallel axes of rotation are used, which can be shifted in phase relative to each other.
