[0014] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0015] Figure 1-3 The middle part includes the lower sand box 1, upper sand box 2, straight sprue 3, filter plate 4, horizontal sprue 5, ingate 6, casting 7, pouring cup 8, sand riser 9, letter plate core 10, first sand core 11, second sand core 12, transition sprue 13, etc.

[0016] like Figure 1-3 As shown, this utility model is an arc-shaped plate transverse stacked box casting structure, including an upper sand box 2 and a lower sand box 1 that cooperate with each other. The lower sand box 1 has a horizontal sprue 5 on its parting surface. The upper sand box 2 contains a first sand core 11 and several second sand cores 12 stacked together. Each second sand core 12 has a casting cavity for forming a casting 7, and a lettering core 10 is placed within the casting cavity to form a mark on the casting 7. The second sand core 12 has an ingate 6 connected to the horizontal sprue 5. The upper sand box 2 also has a sprue 3 connected to the horizontal sprue 5. A pouring cup 8 is placed on the top surface of the upper sand box 2, and the outlet of the pouring cup 8 is connected to the upper inlet of the sprue 3. It can be understood that the inner cavity of the pouring cup 8 has a structure with a large opening at the top and a small opening at the bottom, and the lower outlet of the pouring cup 8 is connected to the inlet of the sprue 3.

[0017] The second sand core 12 is also provided with a sand riser 9, which is located at the top of the casting cavity and is connected to the casting cavity.

[0018] The inlet end of the horizontal pouring channel 5 is equipped with a buffer tank, and a filter plate 4 is installed in the buffer tank.

[0019] The straight gating 3 is connected to the horizontal gating 5 through the transition gating 13.

[0020] One end of the transition runner 13 is connected to the first runner, the second runner, and the transition runner for connecting the first runner and the second runner; the first runner is connected to the straight runner 3, and the second runner is connected to the runner 5 from the bottom.

[0021] The working principle of this utility model is as follows: In the horizontal stacking casting process of the arc-shaped plate, the first sand core 11 and five horizontal second sand cores 12 are stacked together. The second sand core 12 contains the casting 7, the letter plate core 10, the ingate 6, the letter plate core 10, and the sand riser 9. Together with the sprue 3, they form the upper sand box 2. The lower sand box 1 is composed of a filter plate 4, a horizontal sprue 5, and an ingate 6. The upper sand box 2 and the lower sand box 1 are connected together by fastening bolts. Molten iron enters the sprue 3 through the pouring cup 8 placed on the upper sand box 2. Then, the molten iron enters the filter plate 4 through the sprue 3. After filtration, the molten iron enters the horizontal sprue 5 and then the ingate 6 connected to the horizontal sprue 5. The molten iron then fills the casting 7 and the sand riser 9 upwards. Thus, when the molten iron cools in the mold, the sand riser 9 provides feeding to the casting 7, resulting in a dense casting 7. The casting 7 is an arc-shaped plate. Understandably, the right side of the first sand core 11 serves as the limiting plane for the leftmost casting 7.

[0022] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
