machine (1) for moulds (2) for metal casting (10) comprising:—a squeeze plate (3) carrying a first mould pattern (32)—a horizontally movable piston (31) for operating the squeeze plate (3) and a finished mould block (2),—a sand supply system (7)—a swing plate (4) carrying a second mould pattern (42), the swing plate (4) is configured to be translatorily movable in a horizontal direction to a released position (4r) and further to be pivotable upwardly to a sidestep position (4s),—a feeder element insertion configuration (50) wherein one or plurality of feeder elements (5) are configured to be attached to the second mould pattern (42) when during operation the swing plate (4) carrying the second mould pattern (42) is pivoted to the sidestep position (4s). ## Claims ### Claim 1 An arrangement in a ram-up machine (1) for moulds (2) for metal casting (10) comprising: a squeeze plate (3) carrying a first mould pattern (32), a horizontally movable piston (31) for operating the squeeze plate (3) and a finished mould block (2), a sand supply system (7) that provides mould sand (70), a swing plate (4) carrying a second mould pattern (42), the swing plate (4) configured to be translatorily movable in a horizontal direction to a released position (4r) and further to be pivotable upwardly to a sidestep position (4s), a feeder element insertion configuration (50), wherein one or plurality of feeder elements (5) are configured to be attached to the second mould pattern (42) when, during operation, the swing plate (4) carrying the second mould pattern (42) is pivoted to the sidestep position (4s) and an insertion frame (54) where each of the one or more feeder elements (5) is located in a mutually correct position to be set to the second mould pattern (42). ### Claim 2 (depends on 1) The arrangement of claim 1, further comprising another actuator (52) loading the feeder elements (5) to or for the insertion frame (54). ### Claim 3 (depends on 1) The arrangement of claim 1, further comprising an actuator (51) for inserting the feeder elements (5) to their positions at the second mould pattern (42). ### Claim 4 (depends on 1) The arrangement of claim 1, further comprising an actuator (51) having an operable insertion frame (511) comprising set positions for the feeder elements (5). ### Claim 5 (depends on 1) The arrangement of claim 1, further comprising a securing connection between the 25 second mould pattern (42) and the feeder element (5) for securing the feeder element (5) to the second mould pattern (42). ### Claim 6 (depends on 1) The arrangement of claim 1 wherein the feeder element insertion configuration (50) is also configured for inserting the feeder element (5) in an inclinded position, to prevent a rotation of the feeder element, to insert a chill for casting, to insert a core and/or to insert a filter. ### Claim 7 A method for ramming up moulds for metal casting in a vertical parting surface ram-up machine comprising the steps of: after completing a squeeze of a mould block (2) for metal casting, pushing the mould block (2) to an intermediate position (4i), a swing plate (4) carrying a second mould pattern (42) is separated from the mould block (2) by a translatory move to a released position (4r) and then pivoted upwardly to a sidestep position (4s), pushing the mould block (2) out of the ram-up machine by horizontally movable piston (31) operating the squeeze plate (3) carrying a first mould pattern (32), after pushing the mould block (2) out, the squeeze plate (3) returns to an initial position (3i) to be ready for mould sand (70) to be supplied, pivoting the swing plate (4) downwardly to the released position (4r) and then moved translatory to a ram-up position (4u), supplying the mould sand (70) forming the mould block (2) to a space (20) formed between the squeeze plate (3) located in the initial position (3i) and the swing plate (4) located in the ram-up position (4u), moving the squeeze plate (3) and/or swing plate (4) toward each others so that the loose mould sand (70) is rammed up or compressed to form the mould block (2), after the swing plate (4) carrying the second mould pattern (42) is pivoted upwards to the sidestep position (4s) and the sqeeze plate (3) is removing the finished mould block (2), using a feeder element insertion configuration (50) to attach one or more of feeder elements (5) to the second mould pattern (42), the one or more of the feeder elements (5) being attached substantially vertically to the second mould pattern (42), when the swing plate (42) is pivoted again downwards and moved to the ram-up position (4u), the feeder elements (5) are located in substantially horizontal direction in their positions, the supplied mould sand (70) covers the feeder elements (5) and when the mould sand (70) is compressed, a cavity inside the feeder element (5) forms a part of mould cavity in the mould block (2) and an insertion frame (54) where each of the one or more feeder elements is located in a mutually correct position to be set to the second mould pattern (42). ### Claim 8 (depends on 7) The method of claim 7 further comprising using an actuator (51) which inserts the feeder elements (5) to their positions at the second mould pattern (42). ### Claim 9 (depends on 7) The method of claim 7 further comprising using an actuator (51) having an operable insertion frame (51l) comprising set positions for the feeder elements (5). ### Claim 10 (depends on 7) The method of claim 7 further comprising using an actuator (52) loading the feeder elements (5) to or for the insertion frame (54). ### Claim 11 (depends on 7) The method of claim 7 further comprising using a securing connection between the feeder element (5) and the second mould pattern (42) for securing the the feeder element (5) to the second mould pattern (42) by inserting the feeder element (5) to its position on the second mould pattern (42). ### Claim 12 (depends on 7) The method of claim 7 comprising method step wherein the feeder element insertion configuration (50) may insert the feeder element (5) in an inclinded position, prevent a rotation of the feeder element, insert a chill for casting, insert a core and/or to insert a filter.
