A casting die is formed from a mold half with a mold insert disposed at least partly in a relief of the mold half. The mold insert is mounted movably in the relief.

A low-pressure aluminum casting mold and a low-pressure aluminum casting process for a motor rotor. The low-pressure aluminum casting mold includes an upper blade profile assembly, a lower blade profile assembly, a rotor core, a dummy shaft and a diverter. The upper blade profile assembly includes an upper backing plate and an upper mold, and the lower blade profile assembly includes a lower backing plate and a lower mold. The low-pressure aluminum casting mold further includes a first pressing device and four sets of second pressing devices. The low-pressure aluminum casting process includes the steps of cold lamination, heating of the rotor core, mold preparation, hot lamination, and low-pressure casting.

A die casting system including a first die having a first cavity-forming surface, a second die having a second cavity-forming surface and is configured to move with respect to the first die along a first axis, and one or more sliding dies that each have a third cavity-forming surface configured to move with respect to and engage with the first die and the second die. The die casting system further including one or more auxiliary die elements removably coupled to the second die and each having a fourth cavity-forming surface. The one or more auxiliary die elements each extending from the second die in a direction perpendicular to the first axis. The die casting system further including a die cavity for forming a metal part between the first, second, third, and fourth cavity-forming surfaces.
