Abstract: The method for the stepwise production and advancing of sand mold parts in a mold-string foundry plant comprising a station (1) for making mold parts, a pouring station (3) and a conveyor (2) for stepwise advancing of mold parts (101-109) from said station (1) for making mold parts towards said pouring station (3), includes the step of double indexing the mold parts using a first, moveable, part (21) of the conveyor. By double indexing the mold string, the time during which pouring into the molds has to be interrupted can be reduced.

Abstract: Machine for the production of sand molds comprising a machine structure with a molding chamber (3), a front plate (1) and a rear plate (2). The front plate (2) and rear plate (3) are arranged for pressing sand within said molding chamber so as to form a sand mold, and are arranged for receiving respective pattern plates (200) for providing front and rear surfaces of the sand mold with corresponding patterns. The machine further comprises a robot arm (6) arranged for replacing the pattern plates (200), said robot arm being (6) attached to the machine structure, such as to a side (101) of the machine structure.
