Design of die casting die for magnesium alloy DVD housing was described

focusing on the gating system

cooling and holding system as well as pushing mechanism.The key points in gating system design

such as injection angular

filling velocity and buffer packet

were expounded.The three design sketches on die casting processing and die casting dies were analyzed comparatively by CAD/CAE/CAM simulation.The results indicate that the desirable processing parameters as follows:injection pressure of 12.71 MPa

die preheating temperature at 250℃

diameter of spray nozzle of 16.2 mm

pouring at 89 m/s

flow volume at 9.18 L/s

plunger diameter of 80mm and plunger velocity of 1.83 m/s.
