。In FIG. 1, reference numeral 1 denotes a molding device, which is constructed by combining a lower mold 11, a middle mold 12, a horizontal mold 13, an upper mold 14, and an upper auxiliary mold 141. Further, 2 is a cavity of the molding device 1, which has the shape of a vehicle wheel. Reference numeral 121 denotes a nest, which projects from the medium mold 12 and extends into the cavity 2. This insert 121 is for forming a shaft hole of a vehicle wheel. Next, 131 is a runner, which extends laterally in the horizontal mold 13. This runner 131 opens to the side of the cavity 2 (rim forming space) via the weir 3. The other end of this runner 131 has an opening 4 on the outer surface of the horizontal mold 13. 5 is an auxiliary type (“runner changing means” of this invention)
), and is installed in close contact with the outside of the horizontal mold 13. 51 is a dome-shaped main space,
It is formed inside the auxiliary mold 5, and has an opening 511 on the lower surface of the auxiliary mold 5. Further, 52 is a connecting path, which is formed in the auxiliary mold 5 like the main space 51. This connecting path 52 has one end opened into the main space 51 and the other end opened 521 into the left side surface of the auxiliary mold 5 (in FIG. 1). The outer opening 521 of the connecting passage 52 faces the outer opening 4 of the runner 131. Therefore, the molten metal in the main space 51 can flow into the runner 131 after passing through the connection path 52 . 61
is a stalk auxiliary ring, and the lower opening 51 of the auxiliary mold 5
It is in contact with the peripheral edge of 1. Further, 62 is a stalk body, which is connected to the lower side of the stalk auxiliary ring 61. This stalk main body 62 and the stalk auxiliary ring 61
Together, they constitute the "stoke" of this invention. A flat filter 7 is held between the auxiliary mold 5 and the stock auxiliary ring 61. The filter 7 has a mesh shape as shown in FIG. 2, and filters the molten metal supplied to the channel changer 5 via the stalk 6.
