Description

Technical Field

[0001] This utility model relates to the field of aluminum liquid filtration technology, and in particular to a briquetting mold, a briquetting assembly, and an aluminum liquid filtration box. Background Technology

[0002] In the aluminum alloy casting process, the purity of the melt is a key indicator for judging the quality of the product, and the state of the filter plate in the filter tank is one of the key factors reflecting the filtration effect. Currently, impurities in molten aluminum are mainly filtered using ceramic filter plates. However, the density of ceramic filter plates is less than that of molten aluminum, leading to the problem of ceramic filter plates floating during actual filtration. A common solution is to place a denser block on the ceramic filter plate. Existing blocks are usually solid cast iron or steel blocks. In practice, operators place this block in the center of the ceramic filter plate to maintain force balance. However, in actual production, the ceramic filter plate is easily damaged by the block. Moreover, when molten aluminum enters the filter box, gas that cannot escape in time remains at the bottom of the ceramic filter plate near the corresponding position of the block, causing the ceramic filter plate to also "float." Utility Model Content

[0003] Given the problems of ceramic filter plates in existing aluminum liquid filter boxes being easily damaged by the pressing blocks and the existence of "plate floating", it is necessary to provide a pressing block preparation mold, pressing block assembly, and aluminum liquid filter box.

[0004] According to one aspect of this application, a briquetting mold is provided, comprising: a base including a base plate and a mounting shaft extending axially from the base plate; a cylindrical shell placed on the base plate and sleeved on the mounting shaft; a partition assembly including a plurality of partitions extending radially from the mounting shaft to the inner wall of the cylindrical shell to form a plurality of cavities within the cylindrical shell; and a plurality of core guide rods located within the cavities and extending axially from the base plate.

[0005] In one embodiment, the length of the core guide rod is greater than the axial length of the cylindrical shell.

[0006] In one embodiment, in order to facilitate fixing the handle and avoid operational errors when placing the handle, the top surface of the core guide rod is provided with an installation groove.

[0007] In one embodiment, the mounting groove extends radially through the core guide rod.

[0008] In one embodiment, the plurality of said partitions are arranged at equal intervals along the circumference of the mounting axis.

[0009] In one embodiment, the shell includes a plurality of arc-shaped mold plates that surround the mounting shaft and are connected end to end, and a mold clamping bolt that connects two adjacent arc-shaped mold plates.

[0010] In one embodiment, the arc-shaped template includes a semi-circular template body and connecting plates extending radially outward from both ends of the template body, the connecting plates having multiple bolt holes.

[0011] According to another aspect of this application, this application also provides a briquetting assembly made using the briquetting mold described above.

[0012] In one embodiment, the pressing assembly includes a plurality of sub-blocks and a plurality of handles, the sub-blocks having a first plane and a second plane arranged opposite to each other and a vent extending from the first plane to the second plane, and the handles being fixed to the first plane or the second plane.

[0013] According to another aspect of this application, this application also provides an aluminum liquid filter box, comprising: a box body having an upper cavity and a lower cavity; a filter plate constructed between the upper cavity and the lower cavity and communicating with the upper cavity and the lower cavity; and a pressing block assembly, the pressing block assembly being placed in the upper cavity and a plurality of sub-blocks in the pressing block assembly being arranged at intervals on the filter plate.

[0014] In summary, the briquetting mold provided in this application adopts a multi-cavity design. On the one hand, it divides the original 60kg integrated briquetting block into multiple parts, which can be pressed onto the four corners of the filter plate in actual use. This fully utilizes the support function of the filter plate to prevent steps, thereby reducing the effective stress on the filter plate surface and solving the problem of concentrated stress in the middle of the filter plate, which easily leads to cracking, in the traditional method. On the other hand, the split design of multiple sub-blocks means that the contact area between the bottom of each sub-block and the filter plate is small. This, combined with the ventilation holes formed on the sub-blocks by the core guide rod, helps to solve the problem of plate floating caused by large cavitation volume at the bottom of the briquetting block in the traditional technology. In addition, taking the traditional 60kg briquetting block as an example, the sub-blocks produced according to the current four-cavity mold design weigh only 15kg. In the high-temperature environment of aluminum part production, operators can easily lift the briquetting block, thereby reducing the difficulty of subsequent cleaning. It is worth noting that the core guide rod also provides support for the installation of the handle. When actually preparing the briquette, the operator can place the handle on the core guide rod without having to consider the timing of the semi-solidification of the molten metal. This ensures the consistency of the shape of multiple sub-blocks in the briquette assembly and also avoids the problem of the briquette assembly being scrapped because the operator forgot to place the handle.

However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0031] During the aluminum alloy casting process, there is a problem of filter plate drift. A common solution is to place a large weight block in the center of the filter plate to maintain its balance. However, due to the special nature of the filter plate material, ceramic filter plates are commonly used in the industry as aluminum molten material filters. When the weight block is too large, the ceramic filter plate is easily damaged, especially when there is no aluminum molten material in the aluminum molten material filter box. Due to the lack of buoyancy from the aluminum molten material, the entire weight of the weight block is borne by the ceramic filter plate, which often leads to its damage. Using a lightweight weight block cannot effectively maintain the stability of the ceramic filter plate. In actual production, gas can accumulate at the bottom of the weight block, forming cavitation bubbles. In the high-temperature environment inside the aluminum molten material filter box, the excessive pressure of these cavitation bubbles can also cause the weight block to shift and deviate within the aluminum molten material filter box, resulting in the ceramic filter plate drift problem.

[0032] Therefore, it is necessary to provide a briquetting mold, a briquetting assembly, and an aluminum liquid filter box that can solve the above-mentioned technical problems.

[0033] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of the briquetting mold in one embodiment of the present invention. Figure 2 and Figure 3 They are respectively Figure 1 The diagram shows a front view and a side view of the briquetting mold. In one embodiment provided in this application, the briquetting mold consists of a base 10, a cylindrical shell 20, a partition assembly 30, and multiple core guide rods 40. The base 10 includes a base plate 11 and a mounting shaft 12 extending axially from the base plate 11. The cylindrical shell 20 is formed by splicing a pair of semi-circular arc-shaped mold plates 21 together with mold-closing fastening bolts 22. The partition assembly 30 includes multiple partitions 31 extending radially from the mounting shaft 12 to the inner wall of the cylindrical shell 20, forming multiple cavities 201 within the cylindrical shell 20. Each cavity 201 contains a core guide rod 40, which extends axially from the base plate 11. In this way, the cavity formed by the cylindrical shell 20 and the base plate 11 is divided into multiple cavities 201 by the partitions 31, and due to the presence of the core guide rods 40, a through-hole vent 5103 can be formed during the actual molding process of the briquetting. A set of sub-blocks 51 made by the briquetting mold provided in this application constitutes a briquetting assembly 50, and each sub-block 51 has an axially penetrating vent hole 5103. Multiple sub-blocks 51 replace the existing one-piece briquetting block, reducing the volume of cavitation at the bottom of the briquetting assembly 50. Even if cavitation exists, the gas will be discharged in time from the vent hole 5103 of the sub-block 51 and will not stay at the bottom of the sub-block 51 for a long time, thereby avoiding the problem of ceramic filter plate floating.

[0034] Furthermore, such as Figure 2 and Figure 3As shown, the length of the core guide rod 40 is greater than the axial length of the shell 20. In this way, during the casting process, there is no need to consider the liquid level in the cavity 201, and it can be filled directly. The liquid level in multiple cavities 201 is judged based on the top of the shell 20, which simplifies the casting steps and eliminates the need to consider whether the top of the core guide rod 40 will be covered by molten metal.

[0035] Understandably, the core guide rod 40 can also serve as a support for the handle 52. During the casting process, after the molten metal is poured into the cavity 201, the handle 52 can be directly placed on top of the core guide rod 40. Then, wait for the molten metal in the cavity 201 to solidify and connect integrally with the handle 52. There is no need for manual installation of the handle 52, or for manual insertion of the handle 52 while the molten metal is in a semi-solid state. The existence of the core guide rod 40 simplifies the installation steps of the handle 52 and avoids problems such as forgetting to place the handle 52 due to manual operation, or the inability to install the handle 52 due to inaccurate timing of metal semi-solidification.

[0036] Furthermore, such as Figure 1 As shown, the top surface of the core guide rod 40 has a mounting groove 401. This mounting groove 401 is used to engage the handle 52, preventing the handle 52 from wobbling after being placed on top of the core guide rod 40, or from accidentally falling into the cavity 201. It is understood that before casting, the handle 52 can also be engaged in the mounting groove 401 first, ensuring a secure engagement between the handle 52 and the core guide rod 40 before proceeding with the casting process. This also avoids the risk of the handle 52 accidentally falling into the molten metal during the casting process.

[0037] Furthermore, such as Figure 1 As shown, the mounting groove 401 extends radially through the core guide rod 40. This facilitates the installation of the "C"-shaped handle 52, with less stringent requirements on the handle 52's shape; only a rod-like structure is needed. It also facilitates the removal of the molded sub-block 51 by pulling it upwards from the core guide rod 40 during demolding.

[0038] Furthermore, such as Figure 1 As shown, multiple partitions 31 are arranged at equal intervals along the circumference of the mounting shaft 12. Specifically, there are four partitions 31 arranged in a cross structure inside the shell 20. There are four cavities 201, that is, four sub-blocks 51 are prepared at one time through the pressing mold to form a set of pressing assembly 50, which matches the rectangular shape of the ceramic filter plate.

[0039] like Figure 1 As shown, the arc-shaped template 21 includes a semi-circular template body 211 and a connecting plate 212 extending radially outward from both ends of the template body 211. The connecting plate 212 has multiple bolt holes.

[0040] It is understood that in other embodiments, the curvature of the formwork body 211 may also be less than 180°. For example, the cylindrical shell 20 may also be composed of three arc-shaped formwork pieces 21, in which case the curvature of the formwork body 211 is 120°. It is also understood that the curvatures of the multiple arc-shaped formwork pieces 21 may be different, as long as they can form the cylindrical shell 20.

[0041] Optionally, in one embodiment provided in this application, the partition 31 can also be detachably installed on the mounting shaft 12, which facilitates the removal of the side of the molded sub-block 51 from the partition 31 during demolding, thereby reducing the resistance to pulling out the sub-block 51.

[0042] like Figure 4 As shown, the briquetting assembly 50 provided in this application is made from the aforementioned briquetting mold. Multiple sub-blocks 51 in the briquetting assembly 50 are fan-shaped, specifically with a fan-shaped arc of 90°. Specifically, the side circumferential surface of each sub-block 51 consists of two radially extending planes and a short arc surface and a long arc surface connecting the two planes. This facilitates demolding and also allows the briquetting assembly 50 to be assembled together during storage, preventing the sub-blocks 51 from tipping over. Each sub-block 51 has a first plane and a second plane 5102 facing away from each other. A vent extends from the first plane to the second plane 5102, and a handle 52 is fixed to the second plane 5102 of the sub-block 51.

[0043] This application also provides an aluminum liquid filtration box, including a box body, a filter plate, and a pressure block assembly 50; wherein the box body has an upper cavity and a lower cavity, the filter plate is constructed between the upper cavity and the lower cavity and communicates with the upper cavity and the lower cavity, the pressure block assembly 50 is placed in the upper cavity, and a plurality of sub-blocks 51 in the pressure block assembly 50 are arranged at intervals on the filter plate. Specifically, when arranging the pressure block assembly 50, the operator can arrange the plurality of sub-blocks 51 at the top corners of the filter plate. In this way, it helps to balance the force on the filter plate. Usually, the box body has a step at the junction of the upper cavity and the lower cavity to support the filter plate. Placing the four sub-blocks 51 at the edge of the filter plate also helps to reduce and optimize the force distribution on the filter plate, thereby preventing the filter plate from deforming and breaking.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
