Abstract

A method of advancing molds (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), the molds (5) leaving the plant in the form of closely juxtaposed mold parts (5) with the castings (9) in casting cavities (8) at the mainly vertical parting surfaces between successive molds (5), the latter constituting a mold string (F), in which each mold (5) occupies a given length (S) in the longitudinal direction of the mold string (F), the latter after having passed a precision conveyor (6, 16) being transferred to a second conveyor (10, 16, D). Each time the second conveyor (10) receives a mold (5) from the mold string (F), the second conveyor (10) is advanced in a controlled manner through a greater distance (S+s) than the length (S) of the individual mold (5) in the mold string (F), so as to produce an interspace (s) on the second conveyor (10) between consecutive molds (5) along the mainly vertical parting surfaces. The new method makes it possible to improve cooling, shorten the conveying distance, and reduce the production of dust.
