ABSTRACT:
Apparatus for casting a metal article includes a mold having a mold insert provided by cooperating shell and insert core which defines a coolant flow passageway. The insert has a portion disposed adjacent to the mold cavity and, in a preferred embodiment, defines a portion of the mold cavity. The passageway portion disposed adjacent to the mold defining surface of the insert has turbulence inducing elements which establish turbulence of the coolant as it flows therethrough. In a preferred embodiment, the turbulence inducing elements consist of a plurality of generally parallel elongated ribs oriented generally perpendicular to the axial extent of the turbulence inducing portion of the coolant passageway. The apparatus is particularly advantageous for a die casting having thin wall portions disposed upstream in respect of the direction of metal flow from thick wall portions. A corresponding method is provided.
