摘要： A ring valve gate mold device includes: a stationary mold (20) and a movable mold (40) that are disposed so as to be allowed to be joined together and separated from each other; an annular cavity (12) 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 (16) through which molten resin is supplied via a circular gate (18) 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 (26) that moves in the axial direction of the ring valve gate mold device to open and close the circular gate. The sleeve body (26) is disposed at a position radially outward of the supply passage (16) connected to the gate (18).
