Die casting apparatus for a rotor

摘要

An apparatus for die casting a rotor is disclosed, by which the die cast totors do not require reworking processes. An annular inner wall and an annular outer wall of a first mold are projected against an opposite surface of an intermediate die plate facing the movable die plate for inserting the inner wall and the outer wall into a sleeve. An annular first cavity is formed between the inner wall and the outer wall, and a plurality of sprues is penetrated from an upper surface of the first mold to an annular first cavity. A plurality of gates protrude from a bottom portion of the first cabity. Also, sizing bars inject high pressure water through spraying holes to clean the die plates.
