Abstract
A ring valve gate mold device includes: a stationary mold and a movable mold that are disposed so as to be allowed to be joined together and separated from each other; an annular cavity used to form an annular product, the cavity being formed in a mating face that is an upper face of the movable mold; a supply passage through which molten resin is supplied via a circular gate connected to the entire circumference of the annular cavity; and a valve body that opens and closes the circular gate of the supply passage. The valve body is a tubular sleeve body that moves in the axial direction of the ring valve gate mold device to open and close the circular gate. The sleeve body is disposed at a position radially outward of the supply passage connected to the gate.
