Device for handling flaskless moulds

Abstract

A device for handling flaskless moulds relates to foundry equipment and can prove to be most advantageous for use in automatic lines for flaskless horizontal-stack moulding. The device of this invention comprises a stationary bed adapted for arranging moulds, and a mechanism or gear for moving the moulds assembled into a stack. The gear is made as two sprocket endless chains running from both sides of the stationary bed concordantly thereto and carrying grips for retaining a stack of flaskless moulds during its travel along the stationary bed. The top horizontal portions of the chains are provided with guides adapted to draw these portions together above the bed. As a result, smooth bringing of the grips to and from the stack is performed. The above embodiment of the gear enables relatively inexpensive moulding sands to be used and provides an increase in metal capacity of the moulds which retain their intactness, this enhancing the economic efficiency of flaskless moulding and adding to the productivity of foundry equipment.
