テイから順次熔湯が満たされていく。 A casting runner formed in this manner is shown in FIGS. 1 and 2. That is, a vertical runner 2' is provided connected to the sprue 1, a first horizontal runner 3' is provided at the lower end of the vertical runner 2', and a first horizontal runner 3' is provided at an arbitrary position of the first horizontal runner 3'. A second horizontal runner 4' is provided branching off from the first horizontal runner 3', and the cross-sectional area of the first horizontal runner 3' increases from the part close to the vertical runner 2' to the end. The structure is such that it gradually decreases. That is, when the height H of the flow path of the first horizontal runner 3' is constant, its width A is A 1 as shown in FIG.
> A 2 (A 1 is the width of the part near the vertical runner 2', A 2 is the width of the end) and gradually decreases toward the end. Note that by changing H, the cross-sectional area of the flow path may be similarly adjusted so that it decreases toward the end. The second horizontal runner 4' branches in a direction perpendicular to the first horizontal runner 3' at arbitrary positions, and branches in two directions on both sides as shown in Fig. 2. . A second vertical runner 5' is provided at an arbitrary position of the second horizontal runner 4'' formed in the sand mold R, and is connected to a casting cavity 6. In FIG. 2, 16 cavities 6 are shown. When molten metal is injected from sprue 1, it branches into two directions at the first horizontal runner, further branches into two directions at each of the four second horizontal runners, and then flows into each of the second vertical runners 5'. The cavity 6 is then filled with molten metal, starting from the cavity closest to the first horizontal runner 3'.

鋳物を同時に製造できるものである。 The casting runner of the present invention includes a plurality of second horizontal runners 4' that branch from the first horizontal runner 3' and join to the second horizontal runners 4'' of other sand molds R.Thereby,
It becomes possible to join sand mold P and sand mold R during casting,
By joining these sand molds, a plurality of second horizontal runners 4' and 4'' (four in this example) are obtained which communicate with the sprue. A communicating casting cavity 6 can be provided. By increasing or decreasing the number of sand molds R to be joined, the number of cavities can be changed arbitrarily. According to the present invention, a large number of castings can be manufactured simultaneously by one pouring process.
また、本発明によれば、垂直平面で分割した砂
型の分割面に湯道が形成されるから、垂直湯道と
水平湯道を同一の平面に形成することができ、ま
た複雑な形状の湯道も形成が可能となる。 Further, according to the present invention, since the runners are formed on the divided surfaces of the sand mold divided by the vertical plane, the vertical runners and the horizontal runners can be formed on the same plane, and the runners with complicated shapes can be formed. Roads can also be formed.
更に、本発明によれば、第２水平湯道を含めす

は極めて有利である。 Furthermore, according to the present invention, all the runners including the second horizontal runner are formed inside the sand mold, so the temperature of the molten metal does not drop during the process, and the molten metal flows to every corner of the cavity. This is particularly advantageous when pouring into multiple cavities by connecting sand molds.
