METHOD AND ARRANGEMENT FOR CONVEYING MOULDS WITH CASTINGS THEREIN

摘要

In a method of advancing moulds (5), after pouring to form castings (9) in the casting cavities (8), leaving a foundry plant comprising a mould-making station (A, 1-4) and a pouring station (B, 7), said moulds (5) leaving said stations in the form of closely juxtaposed mould parts (5) with the castings (9) in casting cavities (8) at the mainly vertical parting surfaces between successive moulds (5), the latter constituting a mould string (F), in which each mould (5) occupies a given length (S) in the longitudinal direction of the mould string (F), the latter after having passed a precision conveyor (6, 16) being transferred to a second conveyor (10, 16, D), the main novel feature is that each time said second conveyor (10) receives a mould (5) from the mould string (F), the second conveyor (10) is advanced in a controlled manner through a greater distance (S+s) than the length (S) of said individual mould (5) in the mould string (F), so as to produce an interspace (s) on the second conveyor (10) between consecutive moulds (5) along the mainly vertical parting surfaces.
