Technical Field

[0001] The utility model relates to the technical field of precision casting, in particular to a casting runner structure. Background Art

[0002] At present, with the improvement of my country's casting technology level, the international competition in the high-end casting market will become increasingly fierce. The industrial chain development model is the main direction of the future industrial development model and also the key development direction of the foundry industry in the future. With the transformation and upgrading of the traditional foundry industry, the continuous advancement of intelligent manufacturing and green casting, foundry companies have gradually explored a diversified foundry industry chain including high-end equipment manufacturing, intelligent equipment manufacturing, and intelligent casting services.

[0003] The fierce competition in the foundry industry and the increasing aging of workers mean that the survival of foundry companies depends not only on the competition of high-end products but also on the competition of low-end products. Low cost and high efficiency are very important, especially since the product technology of large-scale casting structures has no competitive advantage. At this time, the low cost and high profit brought by the high process yield also bring certain advantages to the foundry industry. The traditional cube, cuboid, and cylindrical molding gates have limited effectiveness, and the alloy liquid contains impurities. Direct pouring affects the pouring quality of the product, resulting in a relatively low single pouring yield and finished product volume, which leads to high casting costs and is not conducive to product competition. To this end, the present application proposes a casting runner structure to solve the above problems. Utility Model Content

[0004] The main purpose of the utility model is to provide a casting runner structure, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a casting runner structure, including a vertical runner, one end of which is connected to a pouring cup, the structure of the vertical runner is a prismatic column structure, the side of the vertical runner is connected to a casting shell through a cross runner, a flow channel for the flow of alloy liquid is arranged in the vertical runner, and a filtering structure is arranged in the flow channel.

[0006] Preferably, the vertical runner is a hexagonal structure, and the horizontal runners are arranged on each side of the vertical runner and are arranged at equal intervals from top to bottom.

[0007] Preferably, the filtering structure comprises a first filter, the first filter is arranged in the flow channel and one end of the first filter close to the pouring cup is an open mouth, and a second filter is arranged inside the first filter close to the open mouth.

[0008] Preferably, the outer side of the first filter is in contact with the inner wall of the flow channel.

[0009] Preferably, the second filter is fixedly connected to the first filter, and the distance between the second filter and the open opening is 3-5 cm.

[0010] Preferably, the mesh number of the first filter is greater than the mesh number of the second filter.

[0011] Preferably, a lifting rod is fixed at the opening of the first filter.

[0012] Compared with the traditional technology, the beneficial effects produced by the utility model are as follows: the utility model can connect multiple groups of castings at a time through the vertical runner with a prismatic structure, which greatly increases the number of castings poured at a single time. At the same time, the filtering structure arranged inside can filter the alloy liquid to prevent impurities from flowing into the casting shell, which greatly improves the finished product rate of castings, improves production efficiency, shortens the casting production cycle, reduces casting costs, is conducive to product competition, improves corporate benefits, is suitable for most casting products of similar sizes, and has strong versatility.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-4 As shown, this embodiment provides a casting runner structure, including a vertical runner 1, one end of the vertical runner 1 is connected to a pouring cup 2, the structure of the vertical runner 1 is a prismatic column structure, the side of the vertical runner 1 is connected to a casting mold shell 4 through a cross runner 3, a flow channel 5 for the flow of alloy liquid is arranged in the vertical runner 1, the interior of the casting mold shell 4 is connected to the flow channel 5 through the cross runner 3, a filtering structure 6 is arranged in the flow channel 5, and the filtering structure 6 is used to filter the alloy liquid.

[0020] In this example, the vertical runner 1 is a hexagonal structure, and the cross runners 3 are arranged on each side of the vertical runner 1 and are arranged at equal intervals from top to bottom. Each cross runner 3 is connected to a casting shell 4, and a gap of at least 2-3 cm is left between two adjacent casting shells 4 above and below.

[0021] like Figure 3-4 As shown, the filtering structure 6 includes a first filter 61, which is arranged in the flow channel 5 and an end of the first filter 61 close to the pouring cup 2 is an open mouth 62, and a second filter 63 is arranged inside the first filter 61 near the open mouth 62. The mesh number of the first filter 61 is greater than the mesh number of the second filter 63, so that the alloy liquid is filtered twice. When the alloy liquid enters the flow channel 5 from the pouring cup 2, it is first filtered once through the second filter 63, and then filtered twice through the side wall of the first filter 61, and then the alloy liquid flows into the casting shell 4 to complete the pouring.

[0022] The planar shape of the flow channel 5 is hexagonal or circular. In this example, the planar shape of the flow channel 5 is circular, the matching cross-sectional shape of the first filter 61 is also circular, and the outer side of the first filter 61 is in contact with the inner wall of the flow channel 5, and the height of the first filter 61 is consistent with the length of the flow channel 5.

[0023] The second filter 63 is fixedly connected to the first filter 61, and the distance between the second filter 63 and the open port 62 is 3-5 cm, so that a certain amount of alloy liquid can be retained on the upper part of the second filter 63 to prevent the alloy liquid from surging upward and spraying out to affect the casting.

[0024] A lifting rod 64 is fixed at the opening 62 of the first filter 61. The width of the lifting rod 64 is 0.2-0.5 cm. Two lifting rods 64 are arranged in a cross structure. After the alloy liquid is poured, the filter structure 6 can be lifted out through the lifting rod 64 for the next use, further reducing the use cost.

[0025] Its working principle is: multiple groups of castings can be connected at a time through the vertical runner 1 with a prismatic structure, which greatly increases the number of castings that can be poured at a single time. At the same time, the filtering structure 6 arranged inside can filter the alloy liquid to prevent impurities from flowing into the casting shell 4, which greatly improves the finished product rate of castings, improves production efficiency, shortens the casting production cycle, reduces casting costs, is conducive to product competition, and improves corporate benefits. It is suitable for most casting products of similar sizes and has strong versatility.

[0026] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above description is illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
