First Embodiment
FIG. 1A is a view showing an example of the height of a mold and a casting formed on the mold, which are input to the mold release device according to the present embodiment. A mold 102a shown in FIG. 1A includes an upper mold 103a and a lower mold 104a, and a casting 101a is formed between the upper mold 103a and the lower mold 104a. The casting 101a has a casting 105a to be a product and a hanger portion 106a. Note that FIG. 1A illustrates the case where the maximum heights of the upper mold 103a and the lower mold 104a are both 130 mm and the height of the mold 102a is 260 mm. Further, the upper mold 103a and the lower mold 104a confine the casting 101a by contacting each other at the portions having the respective maximum heights. The protrusion 107a and the pouring portion 108a will be described later.

  FIG. 1B is a view showing another example of the height of the mold and the casting formed on the mold, which are input to the mold release device according to the present embodiment. 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 the 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. The upper mold 103b and the lower mold 104b confine the casting 101b by coming into contact with each other at the portions having the respective maximum heights. The description of the protrusion 107a and the pouring portion 108a, which will be described later, is used for the protrusion 107b and the pouring portion 108b.

  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 a casting 105a and a hanger portion 106a, and the casting 105a and the hanger portion 106a are integrally formed including a portion connecting them. And the hanger hook 31 is arrange | positioned under the hanger part 106a. In addition, the protrusion 107a formed in the part which connects the casting 105a and the hanger part 106a is a structure provided in order for the robot arm to grasp the casting 101a so that it may mention later. In addition, the pouring portion 108a is a portion which becomes a spout at the time of pouring.

  In addition, although the hanger part 106a is T-shaped in FIG. 2, it is not limited to this. The hanger portion 106a may be H-shaped or cross-shaped. Also, although two hangers 106a are provided in FIG. 2, this is used when loading the casting 101a on a 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 used, and the description thereof is 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, while the hanger portion 106b of the mold 102b shown in FIG. 1B is from the mounting surface of the mold 102b. It exists at a height of 225 mm. Therefore, the position where the casting 101b shown in FIG. 1B is applied is 95 mm, that is, about 10 cm higher than the position where the casting 101a shown in FIG. 1A is applied, with respect to the mounting surface. Therefore, when the hanger hook 31 is disposed at the same position as when the casting 101a shown in FIG. 1A is hung when the casting 101b shown in FIG. 1B is hung, the casting 101b may not hook the hanger hook 31. Thus, if the height of the hanger part of the casting in the mold is different, the hanging by the hanger hook may fail. So, in this embodiment, the relative position of the hanger part of a casting and a hanger hook is adjusted by adjusting the angle of the mounting surface which mounted the casting_mold | template.

  In addition, as a mold forming method of a mold, there are a frame punching method and a frame forming method. The height of the mold produced by the framed molding depends on the height of a metal frame which is a frame used for molding the mold. Therefore, in the framed mold, the heights of the molds made of the same metal frame are approximately equal. On the other hand, in the case of frame punching, since the metal frame is not used for molding of the mold, the height of the mold to be produced varies. In such frame punching molds, the heights of the molds are different, and the heights of the hangers are also different. That is, the present invention exhibits sufficient effects when applied to frame punching dies having different mold heights as described above.

  In FIGS. 1A and 1B, although the maximum height of the upper mold and the maximum height of the lower mold are made equal, the present invention is not limited thereto, the maximum height of the upper mold and the maximum height of the lower mold. May be different.

  In the following description, the casting 101a and the casting 101b are collectively referred to as the casting 101, the mold 102a and the mold 102b are collectively referred to as the mold 102, and the upper mold 103a and the upper mold 103b are collectively referred to as the upper mold 103. The lower mold 104a and the lower mold 104b are collectively referred to as the lower mold 104, the cast 105a and the cast 105b are collectively referred to as the cast 105, and the hanger portion 106a and the hanger portion 106b are collectively referred to as the hanger portion 106.
