Abstract
The invention relates to the field of casting, and more particularly to a shell mould (1), and also to methods for manufacturing and using such a shell mould (1). This shell mould (1) has a central cylinder (4) , a plurality of moulding cavities (7) that are arranged in a cluster around the central cylinder (4) and at least one heat shield (13) approximately perpendicular to a main axis (X). The central cylinder (4) extends , along said main axis (X), between a pouring cup (5) and a base (6). Each moulding cavity is connected to the pouring cup (5) by at least one inlet duct (8), and also, by a chicane type selector (9), to a starter (10) in the base (6). The at least one heat shield (13) completely surrounds each of said moulding cavities (7) in a plane approximately perpendicular to said main axis (X).
