A centrifugal casting apparatus is provided. The centrifugal casting apparatus includes an upper mold machined to have an inner contour used to form an upper side surface of a casting, and a lower mold machined to have an inner contour used to form a lower side surface of the casting. An upper motor provides power to rotate the upper mold and a lower motor provides power to rotate the lower mold. The upper motor and the lower motor are operated independently of each other.

Centrifugal casting apparatus and centrifugal casting method

A vacuum centrifugal casting apparatus includes an upper mold having an upper vacuum hole communicating with both a cavity and a space over the upper mold, a lower mold including a lower vacuum hole corresponding to the upper vacuum hole, the lower vacuum hole communicating with both the cavity and a space under the lower mold, a motor configured to rotate the upper mold and the lower mold, a vacuum retaining member having an outer diameter corresponding to the upper vacuum hole, with a molten metal injection hole formed in an upper end of the vacuum retaining member, and a vacuum pump configured to be operated by the motor, and including an inlet communicating with the lower vacuum hole, and an outlet formed to exhaust drawn air.

A centrifugal casting apparatus for different materials may include a mold having a shape corresponding to a shape of an outer surface of a casting to be produced, and having a cavity receiving molten metals therein, a molten metal guide inserted into the mold and configured to guide the molten metals so that the molten metals are separately injected into the mold, a guide fixing support fixing the molten metal guide to a predetermined position, and a motor configured to rotate the mold around a rotation axis.

Centrifugal casting apparatus for different materials

A differential carrier case with an inserted pipe for high pressure casting may include a mold core into which a first end of a pipe is inserted, a mold core pin fixed to the mold core to fix the mold core and the first end of the pipe, a drive core pin inserted into a second end of the pipe, and a thick portion surrounding an outer portion of the pipe.
