Description

Technical Field

[0001] This utility model relates to the field of metal casting equipment technology, specifically to a metal casting funnel with double-layer filtration and anti-clogging properties. Background Technology

[0002] In the casting process of metal castings, the casting funnel is a key piece of equipment, and its performance directly affects the smoothness of the entire production process and the quality of the product. Currently, common casting funnels on the market have many problems that urgently need to be solved in practical applications. On the one hand, because it is difficult to achieve complete purity in the smelting process of metal raw materials, the resulting molten metal inevitably contains various impurities, such as incompletely melted slag and oxides generated during smelting. If these impurities enter the mold along with the molten metal, they will cause defects such as sand holes and pores on the surface of the casting after it is formed, which will seriously affect the appearance quality and mechanical properties of the casting, and may even cause the casting to be scrapped due to substandard quality, resulting in a waste of raw materials and production costs.

[0003] On the other hand, the internal structure of traditional casting funnels is not rationally designed and lacks an effective mechanism for intercepting and guiding impurities. When impurities in the molten metal gradually accumulate inside the funnel, they can easily clog the discharge channel, causing the flow rate of the molten metal to gradually slow down or even stop completely. Once a blockage occurs, operators have to stop the casting process and clean the funnel, which not only greatly reduces production efficiency and extends the product production cycle but also increases labor maintenance costs. Moreover, frequent cleaning operations may cause wear and tear on the internal structure of the funnel, further shortening its service life. In addition, during the cleaning process, there is the problem of molten metal solidifying inside the funnel and being difficult to remove, causing many inconveniences to the cleaning work. Therefore, designing a new type of casting funnel that can effectively filter impurities and prevent blockage has become an important issue that urgently needs to be addressed in the field of metal casting production. Utility Model Content

[0004] To solve the above problems, the present invention adopts the following technical solution.

[0005] A metal casting funnel with double-layer filtration and anti-clogging features includes a funnel body, a feed hopper on one side of the top of the funnel body, a discharge hopper at the bottom of the other side of the funnel body, a filter baffle between the feed hopper and the discharge hopper, a plurality of through holes evenly distributed on the filter baffle, the filter baffle tilting downwards from the side near the feed hopper toward the side of the discharge hopper, and an impact box is also provided below the feed hopper.

[0006] Preferably, the top of the filter baffle is provided with an anti-impact guide plate on the side facing the feed hopper, and the anti-impact guide plate is an inwardly curved arc structure.

[0012] Preferably, a protective cone sleeve is detachably fitted on the outer side of the cone.

[0013] Preferably, a collection box is detachably installed inside the collection tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention utilizes a dual-layer filtration structure consisting of a filter baffle and an impact box to effectively intercept impurities in molten metal, thereby improving the quality of metal castings.

[0016] The inclined design of the filter baffle, the multi-functional setting of the baffle plate, and the reasonable structure of the impact box and the boss in this utility model can prevent impurities from clogging the funnel. At the same time, the flow rate of the molten metal can be adjusted according to actual needs to ensure the continuity and stability of the casting process and improve production efficiency.

[0017] The design of the anti-impact guide plate, protective cone sleeve, and collection box in this utility model enhances the practicality and durability of the funnel, and facilitates equipment maintenance and cleaning. The design that the bottom diameter of the impact box is larger than the top diameter of the boss effectively prevents molten metal from adhering to the outside of the impact box, further improving the ease of use of the equipment.

[0028] like Figure 1-2As shown in this embodiment, a metal casting funnel with double-layer filtration and anti-clogging features includes a funnel body 1. A feed hopper 2 is located on one side of the top of the funnel body 1 to introduce molten metal into the funnel body 1. A discharge hopper 3 is located at the bottom of the other side of the funnel body 1, through which the filtered molten metal flows into the mold. A filter baffle 4 is provided between the feed hopper 2 and the discharge hopper 3. The filter baffle 4 has several evenly distributed through holes 41, allowing the molten metal to pass through while larger impurities are intercepted on the filter baffle 4, achieving the first layer of filtration. The filter baffle 4 slopes downwards from the side closest to the feed hopper 2 towards the side closest to the discharge hopper 3. This inclined design facilitates the sliding of impurities along the filter baffle 4 under gravity, preventing impurities from accumulating on the filter baffle 4 and causing blockage. An impact box 5 is also provided below the feed hopper 2. When the molten metal enters the impact box 5 from the feed hopper 2, the impact box 5 buffers and performs secondary filtration of the molten metal.

[0029] Furthermore, in this embodiment, an anti-impact guide plate 6 is provided on the side of the filter baffle 4 facing the feed hopper 2. The anti-impact guide plate 6 has an inwardly curved arc structure. The anti-impact guide plate 6 can guide the molten metal to flow smoothly towards the filter baffle 4, avoiding direct impact of the molten metal on the filter baffle 4 and causing splashing.

[0030] In this embodiment, a boss 7 is provided below the discharge hopper 3, and the impact box 5 is located on the top of the boss 7. A slot is provided at the bottom of the impact box 5, and a plug that matches the slot is provided on the top surface of the boss 7. The engagement of the slot and plug ensures a secure connection between the impact box 5 and the boss 7, facilitating the installation and removal of the impact box 5. The bottom diameter of the impact box 5 is larger than the top diameter of the boss 7. This design allows molten metal to flow quickly away from the outside of the impact box 5, preventing it from remaining on the outside. This effectively avoids molten metal adhering to the outside of the impact box 5, reducing cleaning workload and ensuring a clean appearance and a safe working environment.

[0031] In this embodiment, a cone 8 is provided in the middle of the impact box 5, and the top of the cone 8 is lower than the height of the impact box 5. When the molten metal enters the impact box 5, it impacts the cone 8, and the molten metal spreads outward. The impurities carried in it will hit the inner wall of the impact box 5 due to inertia and be deposited, thus achieving secondary filtration of the molten metal.

[0032] In this embodiment, a collection groove 9 is recessed on the funnel body 1 below the filter baffle 4. Impurities that slide off the filter baffle 4 will fall into the collection groove 9, which facilitates the collection and cleaning of impurities.

[0033] The working principle of the above technical solution is as follows:

[0034] In use, first install and secure the impact box 5 by connecting it to the plug on the top surface of the boss 7 via the slot at its bottom. Then pour the molten metal into the funnel body 1 through the feed hopper 2.

[0035] After the molten metal enters from the feed hopper 2, it enters the impact box 5 below. The cone 8 inside the impact box 5 causes the molten metal to spread outwards. The impurities carried in the molten metal collide with the inner wall of the impact box 5 and are deposited, thus achieving secondary filtration.

[0036] After entering the funnel body 1, the molten metal first passes through the filter baffle 4. Larger impurities are intercepted by the through holes 41 on the filter baffle 4, while the molten metal flows through the through holes 41 to the discharge hopper 3. Impurities that slide off the filter baffle 4 fall into the collection tank 9. During the process of the molten metal entering the funnel body 1 from the feed hopper 2, the anti-impact guide plate 6 guides the molten metal to flow smoothly towards the filter baffle 4, reducing the impact on the filter baffle 4 and causing splashing. After double filtration, the molten metal flows out from the discharge hopper 3 and enters the mold for casting. Example 2

[0037] like Figure 3-6 As shown, in this embodiment, a baffle plate 10 is slidably disposed on the side of the filter baffle 4 facing the discharge hopper 3. Slide grooves 42 are provided on the front and rear sides of the filter baffle 4, and the front and rear sides of the baffle plate 10 slide within the corresponding slide grooves 42. By sliding the baffle plate 10, the number of open through holes 41 on the filter baffle 4 can be controlled, thereby adjusting the flow rate of the molten metal to meet different casting requirements. Furthermore, when casting is about to be completed, the baffle plate 10 can also prevent floating debris on the uppermost layer of molten metal from entering, further ensuring the purity of the molten metal entering the mold.

[0038] In this embodiment, a protective cone sleeve 11 is detachably fitted on the outside of the cone 8. The protective cone sleeve 11 can protect the cone 8 from direct impact and corrosion of the molten metal, extend the service life of the cone 8, and can be easily disassembled and replaced when the protective cone sleeve 11 is damaged.

[0039] In this embodiment, a collection box 12 is detachably installed inside the collection tank 9. The collection box 12 is used to collect impurities. When the collection box 12 is full of impurities, it can be removed from the collection tank 9 for cleaning. After cleaning, it can be put back into the collection tank 9. The operation is convenient and quick.

[0040] During the casting process, if it is necessary to adjust the flow rate of the molten metal, the baffle plate 10 can be pulled by the lifting device to change the number of open through holes 41 on the filter baffle plate 4. When the casting is about to be completed, the baffle plate 10 is slid to block some of the through holes 41 on the upper part of the filter baffle plate 4, thereby intercepting the floating objects on the uppermost layer of molten metal and preventing them from entering the mold. Impurities sliding off the filter baffle plate 4 will fall into the collection box 12 in the collection tank 9. When the collection box 12 is full of impurities, it is removed from the collection tank 9 for cleaning, and then put back into the collection tank 9. If the protective cone sleeve 11 on the outside of the cone 8 is damaged, it can be removed and replaced with a new protective cone sleeve 11; when it is necessary to clean or replace the impact box 5, it can be removed from the boss 7. Since the bottom diameter of the impact box 5 is larger than the top diameter of the boss 7, the molten metal can flow away quickly, reducing the work of cleaning the molten metal adhering to the outside of the impact box 5.

[0041] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
