<p>The mould arrangement comprises a mould (10) comprising a bottom plate (12) and two side portions (16, 18). When the side portions (16, 18) are in a first, closed, or a second, open, position thereof, cooling passages (20) formed therein communicate with exits (28) of a plenum chamber (24) beneath the bottom plate (12) so that cooling air can flow from the chamber and through the passages. The exits (28) of the chamber (24) are formed in a distribution plate (26). At least one air supply passage (50; 70) extends in the thickness of the distribution plate (26) to supply air to one or more further cooling passages (60; 80) in the side portions (16,18) to give enhanced cooling in selected regions.</p> |
