Description

Technical Field

[0001] This utility model relates to the field of casting equipment technology, specifically to an auxiliary pouring cup for a pouring ladle. Background Technology

[0002] Ladles are used in foundry workshops for pouring operations. After receiving molten metal in front of the furnace, they are generally transported by overhead crane to the mold for pouring. With the improvement of current production efficiency, some ladles, after receiving molten metal, move directly along a specific route, pouring molten metal into specific molds at regular intervals. This production process is extremely efficient and is particularly suitable for the mass production of small workpieces.

[0003] Ladles are generally quite large, while sand molds are typically small. When a certain amount of liquid is injected into the sand mold, splashing is inevitable. Existing technology includes a patent document (CN204912744 U) entitled "A Ladle," which describes a method to prevent splashing by installing a guide plate at the ladle's outlet. This guide plate guides the liquid flow and is suitable for medium to large molds. However, if the runner is significantly small, it is still difficult to pour, resulting in some waste. In mass production of small parts, a specific pouring cup must be used at the inlet end of the runner to increase the inlet area and ensure the molten metal fills the entire cavity. Therefore, a separate pouring cup needs to be made for the top of each sand mold, and then removed after use. This process adds extra workload and affects processing efficiency. Utility Model Content

[0004] To overcome the above-mentioned defects, the purpose of this utility model is to provide an auxiliary pouring cup for a ladle, which has an auxiliary flow guiding device on one side of the ladle body to achieve rapid and stable injection of liquid into the mold to be cast.

[0005] To achieve the above objectives, this utility model provides an auxiliary pouring cup for a pouring ladle, comprising a slide rail and a pouring ladle body. A slide block slides on the slide rail, and a pouring ladle support is provided on the slide block. Rotation shafts are provided on both sides of the pouring ladle body, and the pouring ladle body is hinged to the pouring ladle support via the rotation shafts. An auxiliary flow guiding device is provided on the pouring ladle support, and the auxiliary flow guiding device is located on one side of the rotation direction of the pouring ladle body. The auxiliary flow guiding device includes a support frame and an auxiliary pouring cup. The support frame is fixedly connected to the pouring ladle support, and the auxiliary pouring cup is detachably connected to the support frame, and the auxiliary pouring cup is located below the pouring ladle body in the rotation direction.

[0006] Preferably, support plates are fixedly provided on both sides of the auxiliary pouring cup, and the support plates are fixedly connected to the ends of the support frame. The support plates are fixedly connected to the support frame by multiple limiting bolts.

[0007] Preferably, each of the support frames has a limiting groove at its end for engaging the support plate.

[0008] Preferably, an arc-shaped flow guide plate is fixedly provided on the inner wall of the auxiliary pouring cup, and the arc-shaped flow guide plate is close to one side of the pouring ladle body.

[0009] Preferably, the auxiliary pouring cup is wider at the top and narrower at the bottom, and the middle of the auxiliary pouring cup is also provided with an arc-shaped groove for locking the filter screen.

[0010] The beneficial technical effects achieved by this utility model after adopting the above technical solution are as follows:

[0011] 1. Because an auxiliary flow guiding device is provided on the ladle support, located on one side of the ladle body's rotation direction; the auxiliary flow guiding device includes a support frame and an auxiliary pouring cup. The support frame is fixedly connected to the ladle support, and the auxiliary pouring cup is detachably connected to the support frame, and the auxiliary pouring cup is located below the ladle body's rotation direction. The ladle body has a very large volume. Adding an auxiliary pouring cup in the direction of liquid pouring guides the liquid, ensuring accurate pouring into the casting mold. In the above operation, it is not necessary to prepare a separate pouring cup for each mold, thus simplifying the mold making process and the subsequent processing of castings. Moreover, since the size of the auxiliary pouring cup is fixed, the pouring volume for parts in the same batch is basically the same each time, thus significantly saving molten metal and reducing production energy consumption.

[0012] 2. Since each end of the support frame is provided with a limiting groove for engaging the support plate, the auxiliary pouring cup is detachably connected to the support plate through the limiting groove. The size of the pouring cup can be changed as needed to adapt to various types of workpieces to be cast, and the damaged auxiliary pouring cup can also be quickly replaced.

[0013] 3. An arc-shaped guide plate is fixed on the inner wall of the auxiliary pouring cup to guide the flow of molten metal and ensure the smoothness of the flow. In order to filter the filter residue formed by the natural cooling of the molten metal, an arc-shaped slot for holding the filter screen is also provided in the middle of the auxiliary pouring cup. When in use, the filter screen can be placed directly in the arc-shaped slot, and the operation steps are extremely simple. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0022] See Figure 1-Figure 2 This invention provides an auxiliary pouring cup for pouring ladles, comprising a slide rail 1 and a pouring ladle body 2. A slide block 11 slides on the slide rail 1, and a pouring ladle support 12 is provided on the slide block 11. Rotating shafts 21 are provided on both sides of the pouring ladle body 2, and the pouring ladle body 2 is hinged to the pouring ladle support 12 through the rotating shafts 21. An auxiliary flow guiding device 3 is provided on the pouring ladle support 12, and the auxiliary flow guiding device 3 is located on one side of the rotation direction of the pouring ladle body 2. The auxiliary flow guiding device 3 includes a support frame 31 and an auxiliary pouring cup 32. The support frame 31 is fixedly connected to the pouring ladle support 12, and the auxiliary pouring cup 32 is detachably connected to the support frame 31, and the auxiliary pouring cup 32 is located below the discharge port in the rotation direction of the pouring ladle body 2. This invention is more suitable for mass production. The slide rail 1 is generally directly fixed, and the bottom of the slide block 11 is provided with a bearing, allowing the slide block 11 to move along the slide rail 1. The ladle body 2 is hinged to the ladle support base 12 via a rotating shaft 21. As needed, several casting molds 4 are placed along the length of the slide rail 1, and the positions of the sprue openings are determined. After the ladle body 2 is filled with molten metal, it moves along the slide rail 1. Upon reaching the designated position, it slowly rotates at a certain angle, pouring molten metal into each casting mold 4. The auxiliary pouring cup 32 has a larger upper opening to receive the liquid and a smaller lower opening to guide the flow, ensuring that the liquid is smoothly poured from the injection port into the cavity of the casting mold 4 each time it is poured. The size of the ladle body 2 is fixed, and the position of the rotating shaft 21 is also fixed; therefore, the length of the support frame 31 is fixed, and the auxiliary pouring cup 32 is simply positioned on the rotation trajectory of the ladle body 2. The rotation and tilting technology of the ladle body 2 is a mature existing technology and will not be described in detail further.

[0023] The auxiliary pouring cup 32 of this invention has support plates 321 fixedly mounted on both sides. The support plates 321 are fixedly connected to the ends of the support frame 31, and the support plates 321 are fixedly connected to the support frame 31 by multiple limiting bolts. Due to the addition of the auxiliary flow guiding device 3, an appropriate model of auxiliary pouring cup 32 is selected according to the size of the mold 4 to be cast. If the mold 4 to be cast is small, the opening at the lower end of the auxiliary pouring cup 32 should be as small as possible for stability and to prevent splashing. After selecting an auxiliary pouring cup 32 of appropriate size, it is fixed in the limiting groove 311 at the end of the support plate 321 and then secured with bolts. The limiting groove 311 can be the top opening or the front opening of the support plate 321; its function is to ensure the accuracy of the installation position and to limit the movement.

[0024] The auxiliary pouring cup 32 of this invention has an arc-shaped guide plate 323 fixedly provided on its inner wall, which is close to the side of the ladle body 2. The arc-shaped guide plate 323 is used to form a smoother slope for the molten metal, which can reduce the amount of air bubbles entering the mold cavity. In particular, when the molten metal just comes into contact with the inner wall of the auxiliary pouring cup 32, it can reduce the drop of the liquid.

[0025] The auxiliary pouring cup 32 of this invention is wider at the top and narrower at the bottom. The middle of the auxiliary pouring cup 32 is also provided with an arc-shaped groove 322 for holding the filter screen. The upper opening of the auxiliary pouring cup 32 should be as large as possible, and the size of the lower opening is set according to needs, generally to match the width of the liquid inlet of the mold 4 to be cast. The arc-shaped groove 322 can be used not only for guiding the flow but also for placing the filter screen (not shown in the figure), especially near the tail end of the mold 4 to be cast. Due to natural cooling, a certain amount of solid residue will float in the liquid inside the ladle body 2. After placing the filter screen, the liquid can be filtered as it passes through. After use, the filter screen can be directly removed. The filter screen is generally cup-shaped and can be placed directly in the middle of the auxiliary pouring cup 32. This is a mature existing technology with extremely wide applications in the casting field.

[0026] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
