A device mountable in a die casting installation which defines a flow path for the supply and flow of a heat transfer medium adjacent to a region of a die component of the installation, whereby the extraction of heat energy at said region from a metal being cast in the installation is able to be retarded or accelerated such as by selection of the heat transfer medium and/or its flow rate along the flow path. The device can be mountable adjacent to a sprue region of the installation such that, with the supply of the heat transfer medium at a sufficient flow rate, the cooling of metal in the sprue region is able to be accelerated where the medium is a coolant or sprue region is able to be heated where the medium is adapted to provide heat energy input. Alternatively, the device can include a conduit system mountable in the die component of the installation and through which the heat transfer medium is able to be supplied for the extraction of heat energy from a section of metal cast in a die cavity defined by the installation, and an insert at a leading end thereof which is adapted to control the extraction of heat energy from a localised region of the metal at said section and to conduct the heat energy to heat transfer medium in the conduit system, wherein the device is adapted to be received in the die component such that a surface of the insert defines a part of, and is exposed at, the cavity so as to be in direct thermal contact with the cast metal at said localised region. |
