Description

Technical Field

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

[0002] The pouring cup is a very important component in the pouring system. During the pouring process, the pouring cup receives the molten metal flow from the ladle and introduces it into the sprue to prevent over-pouring and overflow; it prevents the flow from directly rushing into the sprue and reduces the impact of the liquid flow on the mold. In addition, the pouring cup also has a certain slag blocking effect. When using a ladle for pouring, the metal hydraulic head is high, the impact force is large, and the flow rate is difficult to control, so it is even more necessary to use a pouring cup. However, the current pouring cup is generally an ordinary funnel shape, which is prone to produce eddy currents, causing the liquid to contain gas and causing pores in the casting. Moreover, when the ladle pours the liquid into the pouring cup, the liquid flow rate is fast, the pouring cup is subjected to greater force, and the pouring cup is easily damaged.

[0003] CN202121855350 discloses a pouring cup for casting, which includes: a cup body, the cup body is formed with a pouring channel; a base arranged at the bottom of the cup body, the base having an opening connected to the outlet of the pouring channel; and reinforcing ribs arranged on the side of the cup body, and the lower end of the reinforcing ribs extends to the base. The reinforcing ribs of the pouring cup are arranged on the side of the cup body, and the lower end of the reinforcing ribs extends to the base, thereby enhancing the strength of the cup body and the firmness of the connection between the cup body and the base and achieving a lightweight design. However, the reinforcing ribs only strengthen part of the strength of the cup body. In the process of liquid entering the pouring cup and the liquid entering the bottom, the top and bottom of the pouring cup are subjected to greater force, and the pouring cup is prone to damage, which affects production.

[0004] The technical problem to be solved by the utility model is: how to improve the structural strength of the pouring cup during liquid injection. Utility Model Content

[0005] The main purpose of the utility model is to provide a pouring cup, by designing the wall thickness of the upper cup body and the lower cup body to be a gradually increasing structure, the structural strength of the upper and lower parts of the pouring cup is improved, thereby preventing the upper and lower cup bodies from being damaged due to a large impact when the pouring cup is just filled with liquid and when the liquid enters the lower cup body.

[0006] To achieve the above objectives, the technical solutions adopted in this application are:

[0007] A pouring cup comprises a cup body; the cup body is provided with a gradually narrowing pouring channel; the pouring channel is provided with a pouring position; the cup body gradually narrows on the side away from the pouring position in the horizontal plane projection; the cup body is formed by connecting an upper cup body, a middle cup body and a lower cup body; the wall thickness of the upper cup body and the wall thickness of the lower cup body both gradually increase along the feeding direction.

[0008] Preferably, the middle cup body is connected to the upper cup body and the lower cup body respectively in an upwardly inclined manner; the wall thickness of the middle cup body at a side close to the pouring position is greater than the wall thickness at a side away from the pouring position.

[0009] Preferably, the wall thickness of the middle cup body at a side close to the pouring position is equal along the feeding direction; and the wall thickness of the middle cup body at a side away from the pouring position gradually increases along the feeding direction.

[0010] Preferably, an annular reinforcement rib is provided on the outer periphery of the upper cup body.

[0011] Preferably, a direct current channel connected to an external flow channel is provided at the bottom of the lower cup body; the direct current channel is communicated with the pouring channel.

[0012] Preferably, the direct current channel is in a cylindrical, square or hexagonal shape.

[0013] Preferably, the outer circumferences of the upper cup body, the middle cup body and the lower cup body decrease sequentially.

[0014] Compared with the prior art, this solution has the following beneficial effects:

[0015] In the pouring cup of this case, when liquid is just poured, the impact force of the liquid on the pouring cup is relatively large. By designing the wall thickness of the upper cup body to gradually increase, the structural strength of the upper cup body is improved to prevent the upper cup body from being damaged during liquid pouring and causing liquid to flow out; when the liquid enters the middle cup body, the liquid impacts the side away from the pouring position. By designing the wall thickness of the middle cup body away from the pouring position to gradually increase, its ability to withstand impact is enhanced; when the liquid enters the lower cup body, the casting channel becomes smaller, and the wall thickness of the lower cup body is designed to gradually increase to improve the structural strength, thereby improving the overall structural strength of the pouring cup.

[0016] Secondly, by gradually narrowing the pouring channel on the side away from the pouring position in the horizontal plane projection, the flow rate of the liquid can be slowed down to prevent the generation of eddy currents and the impact force on the inner wall of the pouring cup.

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. The components of the present application implemented as described and shown in the drawings here can be arranged and designed in various different configurations.

[0024] Example 1

[0025] refer to Figure 1-6 A pouring cup comprises a cup body 1; the cup body 1 is provided with a gradually narrowing pouring channel 2; the pouring channel 2 is provided with a pouring position 3; the cup body 1 gradually narrows on the side away from the pouring position 3 in the horizontal plane projection; the cup body 1 is connected by an upper cup body 11, a middle cup body 12 and a lower cup body 13; the wall thickness of the upper cup body 11 and the wall thickness of the lower cup body 13 both gradually increase along the feeding direction.

[0026] In this embodiment, the upper cup body 11 is used to receive the pouring of the ladle, the middle cup body 12 is used to make the liquid flow to the lower cup body 13, and plays a guiding role. The bottom of the lower cup body 13 is connected to the mold. The projection of the pouring cup on the horizontal plane is peach-shaped, and the pouring position 3 and the outlet of the pouring channel 2 are not on the same axis. When the pouring cup is filled with liquid, the upper cup body 11 and the lower cup body 13 are the positions mainly impacted by the liquid. The wall thickness of the upper cup body 11 is gradually increased along the feeding direction. When the liquid is poured into the pouring position 3, the inner wall of the middle section of the upper cup body 11 is subjected to a greater impact force of the liquid. By setting the wall thickness gradually increasing, the structural strength of the upper cup body 11 can be increased to prevent the pouring cup from having a gap. Secondly, since the width of the casting passage in the lower cup body 13 is small, when the liquid enters the lower cup body 13, the flow rate of the liquid is large and the impact force will become larger. Therefore, the wall thickness of the lower cup body 13 is gradually increased along the feeding direction to prevent the lower cup body 13 from having a gap and facilitate the installation of the pouring cup on the mold. In this way, the overall structural strength of the pouring cup can be increased.

[0027] Secondly, the side of the cup body 1 away from the pouring position 3 in the projection of the horizontal plane gradually narrows, which can slow down the flow rate of the liquid during pouring and avoid liquid splashing and eddy current.

[0028] Preferably, the middle cup body 12 is connected to the upper cup body 11 and the lower cup body 13 respectively in an upwardly inclined manner; the wall thickness of the middle cup body 12 close to the pouring position 3 is greater than the wall thickness of the side away from the pouring position 3.

[0029] In this embodiment, the middle cup body 12 is connected to the upper cup body 11 obliquely upward, so that the liquid can flow to the lower cup body 13. The liquid mainly flows downward along one side of the pouring position 3. Therefore, the wall thickness of the middle cup body 12 close to the pouring position 3 is designed to be greater than the wall thickness of the side away from the pouring position 3, which not only ensures the overall structural strength of the middle cup body 12, but also saves materials and reduces costs.

[0030] Preferably, the wall thickness of the middle cup body 12 on the side close to the pouring position 3 is equal along the feeding direction; and the wall thickness of the middle cup body 12 on the side away from the pouring position 3 gradually increases along the feeding direction.

[0031] In this embodiment, the liquid flows into the lower cup body 13 through the middle cup body 12. Since the side of the middle cup body 12 close to the pouring position 3 is not subjected to impact, only a uniform wall thickness needs to be designed. However, when the liquid enters the lower cup body 13 from the middle cup body 12, the liquid will have a partial impact force on the side of the middle cup body 12 away from the pouring position 3. Therefore, the wall thickness of the side of the middle cup body 12 away from the pouring position 3 gradually increases along the feeding direction, so that it bears the impact of the liquid. Different wall thicknesses can be designed according to the flow of the liquid, reducing the used materials and reducing costs.

[0032] Preferably, an annular reinforcing rib 4 is provided on the outer periphery of the upper cup body 11 .

[0033] In this embodiment, the wall thickness of the upper cup body 11 gradually increases along the feeding direction by providing an annular reinforcing rib 4 on the outer peripheral surface of the upper cup body 11. The annular reinforcing rib 4 can not only increase the thickness of the upper cup body 11, but also make the upper cup body 11 have a bulge to facilitate the staff to carry the pouring cup.

[0034] Preferably, a direct flow channel 5 connected to an external flow channel is provided at the bottom of the lower cup body 13 ; the direct flow channel 5 is communicated with the pouring channel 2 .

[0035] In this embodiment, by providing the straight flow channel 5, the liquid can enter the mold evenly and is convenient to connect with the external flow channel.

[0036] Preferably, the shape of the direct current channel 5 is cylindrical, square or hexagonal. The shape of the direct current channel 5 is preferably cylindrical.

[0037] Preferably, the outer circumferences of the upper cup body 11, the middle cup body 12, and the lower cup body 13 decrease in sequence.

[0038] In this embodiment, the outer circumferences of the upper cup body 11, the middle cup body 12, and the lower cup body 13 are reduced in sequence, so that the overall outer circumference of the pouring cup is continuously reduced along the feeding direction, reducing manufacturing materials and reducing costs.

[0039] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
