The mold 102b shown in FIG. 1B includes an upper mold 103b and a lower mold 104b, and a casting 101b is formed between the upper mold 103b and the lower mold 104b. The casting 101b has a casting 105b as a product and a hanger portion 106b. Note that FIG. 1B illustrates a case where the maximum heights of the upper mold 103b and the lower mold 104b are both 225 mm and the height of the mold 102b is 450 mm. Further, the upper mold 103b and the lower mold 104b are in contact with each other at the portions having the maximum heights thereof to confine the casting 101b. Regarding the protrusion 107b and the pouring portion 108b, the description of the protrusion 107a and the pouring portion 108a, which will be described later, will be incorporated.

Further, FIG. 2 is a plan view showing the positional relationship of the casting 101a shown in FIG. 1A in the mold 102a. As shown in FIGS. 1A and 2, the casting 101a includes the casting 105a and the hanger portion 106a, and the casting 105a and the hanger portion 106a are integrally formed including a portion connecting them. Then, the hanger hook 31 is arranged below the hanger portion 106a. The protrusion 107a formed at the portion connecting the casting 105a and the hanger portion 106a has a configuration provided for the robot arm to grip the casting 101a as described later. Further, the pouring portion 108a is a portion serving as a sprue at the time of pouring.

Although the hanger portion 106a is T-shaped in FIG. 2, the hanger portion 106a is not limited to this. The hanger portion 106a may be H-shaped or cross-shaped. Further, in FIG. 2, two hanger portions 106a are provided, which are used when the casting 101a is placed on the pallet carriage in a later step.

Further, since the positional relationship between the casting 101b and the mold 102b shown in FIG. 1B is the same as the positional relationship between the casting 101a and the mold 102a, FIG. 2 is incorporated and the description thereof will be omitted.

The hanger portion 106a of the mold 102a shown in FIG. 1A exists at a height of 130 mm from the mounting surface of the mold 102a, whereas the hanger portion 106b of the mold 102b shown in FIG. 1B is located from the mounting surface of the mold 102b.
