[0002] Investment casting, also known as lost-wax casting, includes processes such as wax pressing, wax trimming, tree assembling, slurry dipping, wax melting, metal liquid pouring, and post-treatment. Lost-wax casting uses wax to make a wax pattern of the part to be cast. A silica sol slurry is coated on the wax pattern. After the coating is completed, a mold shell is made. Then the wax inside the mold shell is melted and removed. After the mold shell is baked, molten metal is poured into the pouring gate. After cooling, the required part is made.

[0003] As a part of the casting process, the pouring gate bar has an important impact on the quality and shape of the final casting. By reasonably selecting and designing the pouring gate bar, various variables in the casting process can be effectively controlled to ensure that the final castings meet the requirements.

[0004] However, during the casting process, the cover plate is exposed to the environment of high-temperature molten metal and sand mold, resulting in the possibility that sand grains may adhere and solidify on the surface of the cover plate. Content of the Utility Model

[0005] To make up for the above deficiencies, the utility model provides a staggered riser for increasing the yield rate, aiming to improve the problem that during the casting process in the prior art, the cover plate is exposed to the environment of high-temperature molten metal and sand mold, resulting in the possibility that sand grains may adhere and solidify on the surface of the cover plate.

[0007] Further, the protective component includes a locking bolt, the locking bolt is threadedly connected to the outside of the connecting rod, a cover plate is arranged inside the cushion plate, a gasket is arranged at the top of the cover plate, and the locking bolt is arranged on the top of the gasket.

[0008] Further, the connecting rod is threadedly connected inside the cover plate.

[0009] Further, the horizontal sprues are arranged with different lengths.

[0010] Further, the connecting rod is arranged inside the gasket.

[0011] Further, a hook is fixedly connected to the top end of the connecting rod.

[0012] The utility model has the following beneficial effects:

[0013] 1. In the utility model, by designing the pouring runners with different lengths, the staggered group welding of castings can be realized, and the production efficiency can be improved.

[0014] 2. In the utility model, through the clamping protection of the cover plate by the cushion plate and the gasket, the problem of sand adhesion on the upper cover plate of the gate rod can be effectively solved, ensuring the smooth progress of the casting process and the stable improvement of the quality of castings.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Referring to Figure 1 and Figure 2 , an embodiment provided by the present utility model: a staggered structure riser for increasing the production rate, including a pouring cup 1, a vertical runner 2 is fixedly connected to the bottom of the pouring cup 1, horizontal runners 3 are fixedly connected to the outside of the vertical runner 2, a cushion plate 5 is arranged on the top of the pouring cup 1, a connecting rod 7 is arranged inside the cushion plate 5, a protective component is arranged outside the connecting rod 7, the protective component is used to protect the cover plate 4, the protective component includes a locking bolt 8, the locking bolt 8 is threadedly connected to the outside of the connecting rod 7, a cover plate 4 is arranged inside the cushion plate 5, a gasket 9 is arranged on the top of the cover plate 4, and the locking bolt 8 is arranged on the top of the gasket 9.

[0021] The solution is injected into the rod body through the pouring cup 1. The solution flows down through the through vertical runner 2 and will flow out through the horizontal runners 3 in sequence, thereby filling the entire casting cavity. By designing the horizontal runners 3 with different lengths, staggered group welding of castings can be achieved, improving the production efficiency. The cushion plate 5 is used to protect the cover plate 4 from adhering sand. The connecting rod 7 cooperates with the locking bolt 8 to fit the cushion plate 5, the cover plate 4 and the gasket 9 together.

[0022] Refer to Figure 1 and Figure 2 Inside the cover plate 4, there is an internally threaded connecting rod 7. The horizontal runners 3 are arranged with different lengths. Inside the gasket 9, there is a connecting rod 7. At the top of the connecting rod 7, there is a fixedly connected hook 6.

[0023] The connecting rod 7 is used to fix the cover plate 4 so that the cover plate 4 can completely seal the pouring cup 1. The gasket 9 is used to protect the cover plate 4 and prevent the cover plate 4 from adhering sand. The hook 6 is used to rotate the connecting rod 7.

[0024] Working principle: When using this device, the solution is injected into the rod body through the pouring cup 1. The solution flows down through the through vertical runner 2 and will flow out through the horizontal runners 3 in sequence, thereby filling the entire casting cavity. By designing the horizontal runners 3 with different lengths, staggered group welding of castings can be achieved, improving the production efficiency. Place the cover plate 4 inside the cushion plate 5, then place the gasket 9 on top of the cover plate 4, and then thread the connecting rod 7 into the inside of the cover plate 4. The connecting rod 7 tightly covers the gasket 9 and the cover plate 4 through the locking bolt 8.
