Figures 1a and 1b show a model mold for molding the mold of this project using green sand. Figure a is a front view, the left half view shows the squeeze side, and the right half view shows the counter mold. Show the side. Figure b is a side view of both, with the left side showing the counter side and the right side showing the squeeze side. Figures 2a and b are molds made from the model mold in Figure 1, where Figure a is a side sectional view (X-X line sectional view in Figure b), and Figure b is the mold alignment of Figure a. A sectional view (YY line sectional view) in the plane is shown.
Figure 3 is an enlarged view of the part of the weir that connects to the cylindrical cavities on both sides (i.e. Z-Z in Figure 2b).
Line sectional view) is shown. FIG. 4 is an enlarged view showing the structure of the dam in further detail. FIG. 5 is a diagram showing another embodiment of the weir connection procedure.
