Abstract
A die-casting assembly includes a ram and a ram adapter that is connected to the ram. The die-casting assembly further includes a mould holder and a mould that is connected to the mould holder. An attachment device includes a clamp cylinder having an end that removably connects the mould holder to the ram adapter. The mould holder includes a clamp ring that defines a radially projecting engagement flange. The upper mould holder includes a body segment having an upper surface that is removably connected to the clamp ring in a plurality of angular positions. When the clamp ring is damaged during use, the clamp ring can be loosened, rotated relative to the body segment, and tightened to the body segment without requiring repair or replacement. The clamp ring is annular and includes a first plurality of axial bores that provide access to leader pins that are connected to the body segment. The clamp ring includes a second plurality of bores arranged in a first pattern for receiving fasteners that connect the clamp ring to the body segment. The body segment includes a third plurality of bores arranged in a second pattern for receiving the fasteners that connect the clamp ring to the body…
