Verfahren und Vorrichtung zur Herstellung von Gussteilen aus Metallen

Cast aluminium piston - chilled by water spray on crown indirectly and then directly

Aluminium (alloy) castings for pistons of internal combustion engines are cast in cylindrical moulds with a detachable bottom plate and a suspended core for the inner piston contours. The molten metal is cooled indirectly from the bottom of a water spray against the bottom plate. When a zone of 1 - 6cm thickness has become solidified, the bottom plate is removed and the cooling spray is directed immediately against the piston crown. This produces pistons which have a higher strength in certain zones. The 50% shorter solidification time results in a proportional improvement in productivity.

A hermetically sealed disc drive comprising at least one aluminum alloy housing component manufactured with a thermally directed die casting press subassembly is disclosed. In one embodiment, the thermally directed die casting press subassembly comprises a thermally directed funnel gate that is skewed to sample molten material from an off-center portion of the shot sleeve. Disc drive housing components can be manufactured by injecting an aluminum alloy slurry from the shot sleeve through the thermally directed funnel gate and the injection nozzle into the die cavity. The aluminum alloy slurry may be a thixotropic slurry comprising a uniform primary aluminum particle size in the range of approximately 50 to 80 microns. The primary aluminum particles of cast products produced according to the methodology of the present disclosure, with the aforementioned particle size distribution, are free of encapsulated eutectic at the micron scale. 1. A thermally directed die casting press subassembly comprising a shot sleeve , a gate plate , a lower mold plate , and an upper mold plate , wherein:the upper mold plate and the lower mold plate define a die cavity there between;the lower mold plate comprises a gate port, a die port, and an injection nozzle extending from the gate port to the die port across a thickness dimension of the lower mold plate;a major portion of the injection nozzle comprises a contracting nozzle taper along a laminar injection path extending towards the die port;the gate plate comprises a thermally directed funnel gate extending from the shot sleeve to the gate port of the lower mold plate across a thickness dimension of the gate plate;the thermally directed funnel gate comprises a contracting funnel taper along a turbulence-inducing injection path extending towards the gate port of the lower mold plate;the shot sleeve defines a temperature gradient profile rising from relatively low T portions at a periphery of the shot sleeve to relatively high T portions ...
