Drainage system of metal for use in the die-casting magnesium alloy and a process for producing a casting of a magnesium alloy

摘要

"System of disposal of metal for use in the die-casting magnesium alloy and a process for producing a casting of a magnesium alloy.The provision or use.For the die-casting magnesium alloy in a melting state or thixotropic with a pressure casting machine having a mould or matrix that defines a cavity of the matrix.A drainage system of metal which includes a device for tool matrix or mould which defines at least one channel from which a magnesium alloy melting is able to be injeThe force in the matrix.The drainage system of metal is of a form that provides control of the speed of flow of metal within the drainage system.So that substantially all of the metal flowing through the cavity of the matrix is in a state of viscous or semi-solid.The filling of the cavity of the matrix is able to proceed progressively by fronts semi solid metal moving away from a lock or other place of injection.The disposal of the magnesium alloy from the channel may be via at least one region controlled expansion of the drainage system of the metal.The region in which the flow of metal is able to spread laterally, with respect to its direction of injection.With a resulting reduction in the speed of flow in relation to its velocity in the channel.
