Influence of Process Parameters on Mechanical Properties of Integrated Die Casting Rear Floor
The non-heat treatment aluminum alloy AlSi8 was used to produce the integrated die-cast automotive rear floor castings.Through the process optimization of fast injection speed,liquid aluminum temperature and high speed position of punch,the optimum process of production on 7 200 T die casting machine was obtaine.When the process parameters were fast injection speed 6.0 m/s,liquid aluminum temperature 695℃,and the high-speed position of the punch 925 mm,the tensile strength of the back floor casting body≥260 MPa,the yield strength≥115 MPa,and the elongation≥10%,and the mechanical properties met the design requirements.
