The moving die half is the part of the die casting die that moves to open and close the mold. It houses the ejector system that pushes solidified castings out of the cavity after solidification. It works with the fixed die half to form the mold cavity.
Common materials include tool steels such as H13 and P20, maraging steel, and beryllium copper for inserts. The mold base material is often 45# to P20 per GB/T 699, and core material is H13 to SKD61 per ASTM A681, heat-treated to 44–48 HRC.
Key parameters include die height (closed) of 200–800 mm, ejector stroke of 30–150 mm, ejector force of 50–500 kN, clamping force of 1000–40000 kN, surface hardness of 45–52 HRC, surface roughness of Ra 0.4–0.8 µm, guide pin diameter of 20–60 mm, operating temperature of 150–350 °C, and weight of 500–5000 kg. These are reference ranges and must be verified for the specific application.
Regular inspection of guide pins, ejector pins, and surfaces is necessary to ensure alignment and prevent wear. The die should be cleaned and lubricated as recommended by the manufacturer. Any signs of wear, cracking, or deformation should be addressed promptly to avoid defects in castings.
