Abstract
PURPOSE: To prevent an ingate-broken portion from projecting and simplify the subsequent finishing process at the time of casting a circular casting by so setting a mold that the excess metal portions connecting smoothly to the outside circumferential surface of the ingate-broken part of the casting are provided.
CONSTITUTION: A mold is made in such a manner that the excess metal portions 5, 5 continuous to the portion 4 where the ingate provided along the outside circumferential surface 3a of a circular casting 3 such as flywheel is broken are formed on both sides in the circumferential direction of the broken portion 4. Molten iron is cast in this mold to manufacture the circular casting 3. Here, the two excess metal portions 5, 5 are respectively longer than the width of the ingate, connect smoothly at both ends in the circumferential direction of the broken part 4, become gradually less in thickness as they go away circumferentially and finally become continuous to the outside circumferential surface 3a of the circular casting 3; therefore, the machining of the next outside circumferential face 3a may be smoothly performed. Namely, there is no need for removing the broken part 4 of the ingate with a grinder and necessary machining may be performed as cast, thus the finishing process may be considerably simplified.
