Description

Technical Field

[0001] This utility model belongs to the field of metal product casting technology, and specifically relates to a multi-purpose iron press box. Background Technology

[0002] In the casting of large metal products, molten metal needs to be injected into the mold cavity of a sand mold. During the pouring process, a certain pressure is generated when the molten metal is injected into the sand mold cavity. Since liquids can transmit pressure consistently in all directions within a closed container, this causes the pressure of the molten metal to act on the inner surface of the sand mold. If the sand mold does not have sufficient weight or securing measures, this pressure may cause the sand mold to lift upwards, resulting in damage to the sand mold and leakage of molten metal, leading to economic losses and safety hazards.

[0003] Especially for large cast iron parts, the high temperature and high fluidity of molten iron will put greater pressure on the sand mold, increasing the risk of the sand box being lifted, which may lead to casting defects such as flash (molten metal overflows from the sand mold parting surface to form excess flakes) and fire (a large amount of molten metal leaks out, which not only scraps the casting but may also cause safety problems).

[0004] To solve the above problems, the main methods currently used include manual pressing, manual mechanical pressing, and external locking of the boxes.

[0005] 1. Manual pressing is a relatively traditional method, in which workers lift the pressing iron and place it on top of the sand box to press it down. This method is time-consuming and labor-intensive, and poses safety hazards during operation.

[0006] 2. The hand-operated mechanical pressure box uses an eccentric wheel and lever pulling principle. Workers can easily lift and lower the pressure box iron by operating the handle, wheel, and other components, reducing manual labor intensity, improving work efficiency, and lowering safety risks.

[0007] 3. External locking method: This method uses steel clips and screws to connect and lock the box, with the sealing opening secured by steel clips. For some large frame castings, after the box is assembled, four lifting steel clips with screws can be used to lock the box. The locking screws and upper clips are combined into a single unit, which is then hoisted to the locking position by a crane. Locking only requires tightening the lower nut. This method reduces damage to the sand box and extends its service life, but the operation is relatively cumbersome.

[0008] However, these methods commonly use solid iron blocks as ballast material, resulting in serious resource waste and safety hazards. Typically, the weight of the ballast iron should be 4 to 6 times the weight of the casting. For large and medium-sized castings (weighing 10 to 60 tons), even greater weight requirements are placed on the ballast iron. Too light a weight will not meet the ballast requirements, while too heavy a weight will damage the sand box and shorten its service life.

[0009] In addition, the height of the sand box is between 3 and 8 meters, making it very inconvenient to move the pressure iron up and down, and it also takes up space and becomes a burden when not in use. Utility Model Content

[0010] This utility model addresses the aforementioned problems in the existing technology by proposing a multi-purpose iron press box whose weight can be adjusted appropriately according to the process requirements of different castings during actual production.

[0011] This utility model can be achieved through the following technical solutions:

[0012] A multi-purpose iron press box, comprising:

[0013] The box body has a hollow interior forming a filling cavity for adding counterweights. The bottom surface of the box body is a large pressure surface, and one side surface is a small pressure surface.

[0014] The area of ​​the large pressing box surface is larger than that of the small pressing box surface. The large pressing box surface is used as the large operating surface of the sand pressing box, and the small pressing box surface is used as the small operating surface of the sand pressing box.

[0015] As a further improvement of this utility model, the box body is configured as a cuboid structure.

[0016] As a further improvement of this utility model, the two adjacent sides of the small pressure box surface are mounting surfaces, and the mounting surfaces are provided with large surface lifting lugs and small surface lifting lugs.

[0017] As a further improvement of this utility model, at least two sets of large-face lifting lugs are provided and symmetrically distributed on the mounting surface.

[0018] As a further improvement of this utility model, the small face lifting lug is located at the end of the mounting surface away from the large pressure box surface, and at least two sets of the small face lifting lug are provided and symmetrically distributed on the mounting surface.

[0019] As a further improvement of this utility model, a baffle is provided on one side of the top surface of the box, and the three sides of the baffle are respectively connected to the small pressure box surface and the two mounting surfaces.

[0020] As a further improvement of this utility model, the top surface of the box is also provided with a partition plate, and multiple sets of the partition plates are arranged crosswise to form several inlets.

[0022] As a further improvement of this utility model, each of the large and small face lifting lugs is provided with lifting lug reinforcing ribs.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The box has a large pressing surface and a small pressing surface. Whether it is a large or small operating surface of the sand box, effective pressing can be achieved by selecting different pressing surfaces, which greatly improves the versatility and applicability of the equipment and meets the needs of diversified production.

[0026] 2.

Detailed Implementation

[0031] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical methods of the present invention. However, the present invention is not limited to these embodiments.

[0032] like Figure 1-2 As shown, this utility model provides a multi-purpose iron pressing box, comprising:

[0033] The box body 100 has a hollow interior that forms a filling cavity for adding counterweights. This design allows for flexible adjustment of the total weight of the pressure box according to actual needs, to accommodate castings of different sizes and types.

[0034] The bottom surface of the box 100 serves as a large pressing surface 110, which has a large area and is a large operating surface specifically used for pressing sand boxes.

[0035] One side of the box 100 serves as a small pressing surface 120, which has a smaller area than the large pressing surface 110 and is suitable for a small operating surface for pressing sand boxes.

[0036] This design offers greater flexibility. Whether the sand box has a large or small operating surface, effective pressing can be achieved by selecting different pressing surfaces, greatly improving the equipment's versatility and applicability, and meeting the needs of diversified production.

[0037] By adopting an internally filled counterweight block (such as cast iron blocks or stones), users can flexibly increase or decrease the counterweight material according to specific needs, reducing unnecessary material consumption and achieving efficient resource utilization. Furthermore, because the weight of the pressure box can be precisely adjusted according to actual conditions, it avoids potential damage to the sand box caused by excessive weight, ensures sufficient pressing force, and reduces safety risks during the casting process.

[0038] In addition to its basic function of pressing the castings into the box, it can also be used as a safety pad when the castings are unpacked, further expanding its application value and solving the redundancy problem during non-pressing periods.

[0039] Preferably, the housing 100 is configured as a cuboid structure, which allows the housing 100 to simultaneously have a large pressure box surface 110 with a large area and a small pressure box surface 120 with a small area, meeting the adaptability requirements of the sand box for both small and large operating surfaces. Its overall structure is formed by welding multiple steel plates, ensuring that the housing 100 has sufficient strength to effectively resist the pressure of the internal counterweight material and the impact force during external operation, thus ensuring the stability and reliability of the equipment in long-term use.

[0040] Preferably, the two adjacent sides of the small pressure box surface 120 are mounting surfaces 130. The mounting surfaces 130 are provided with large lifting lugs 140 and small lifting lugs 150 to facilitate lifting operations. Specifically:

[0041] At least two sets of large face lifting lugs 140 are provided and symmetrically distributed on both sides of the mounting surface 130. The symmetrical distribution helps to evenly distribute the lifting force and reduce the risk caused by imbalance. When a large operating surface of the sand box is required to be pressed by the large pressure box surface 110, the crane hook is hung on the large face lifting lugs 140.

[0042] The small face lifting lug 150 is located at the end of the mounting surface 130 away from the large pressure box surface 110. At least two sets of small face lifting lugs 150 are provided and symmetrically distributed on the mounting surface 130. This is also to ensure balanced force during the lifting process and avoid safety hazards caused by excessive force on one side. When the small pressure box surface 120 is used to press the large operating surface of the sand box, the crane hook is hung on the small face lifting lug 150.

[0043] By rationally arranging the positions of the large lifting lugs 140 and the small lifting lugs 150, it is ensured that the container 100 can remain horizontal and stable during the hoisting process, reducing the risk of tilting or slipping and improving operational safety.

[0044] Preferably, a baffle 160 is provided on one side of the top surface of the box 100. The three sides of the baffle 160 are respectively connected to the small pressing surface 120 and the two mounting surfaces 130. In actual application, when it is necessary to press the small operating surface of the sand box, the small pressing surface 120 faces downward. At this time, the baffle 160 can play a blocking role to ensure that the counterweight in the filling cavity will not fall out.

[0045] Preferably, the top surface of the box 100 is also provided with a partition plate 170. Multiple sets of partition plates 170 arranged horizontally and multiple sets of partition plates 170 arranged vertically intersect to form a mesh structure and constitute several inlets. The counterweight material is filled into the filling cavity through each inlet.

[0046] The presence of the partition plate 170 allows the filling material to be added to the designated area in a more orderly manner, avoiding the problem of uneven material accumulation and ensuring the uniformity of weight distribution inside the pressure box.

[0047] In addition, the grid structure formed by the horizontally and vertically intersecting partition plates 170 increases the overall rigidity of the box 100, making the box 100 less prone to deformation when subjected to heavy loads. Especially during hoisting, when the box 100 may be subjected to forces in different directions, this reinforced structure can ensure the stability and safety of the box 100.

[0048] Preferably, the mounting surface 130 is also provided with a climbing board 180, which makes it easy for operators to climb to the top of the pressure box to connect the hook, check the internal filling, or perform other necessary operations without the need for additional ladders or other auxiliary tools, thus simplifying the operation process and improving work efficiency.

[0049] Preferably, each set of large face lifting lugs 140 and small face lifting lugs 150 is provided with lifting lug reinforcing ribs 190. By setting lifting lug reinforcing ribs 190, the load-bearing capacity of the lifting lugs can be significantly enhanced, ensuring that they can withstand greater tensile force during the lifting process without deformation or damage, and avoiding safety accidents caused by accidental breakage during the lifting process.

[0050] Preferably, the inner wall of the box 100 is provided with box reinforcing ribs 200. These box reinforcing ribs 200 are used to enhance the strength and stability of the box 100 structure. The more robust internal structure means that it is more stable and reliable when adding or adjusting the counterweight material, ensuring that it will not be deformed or damaged due to internal pressure or external impact when adding or removing the counterweight, and extending the service life of the box 100.

[0051] In addition, the large lifting lug 140 and the small lifting lug 150 have the same structure, both consisting of two symmetrically arranged mounting plates and a support shaft passing through the mounting plates. During lifting, the crane hook is attached to the mounting shaft. This lifting lug structure has good stability and firmness, which helps to reduce the swaying and tilting of the box 100 during the lifting process.

[0052] Furthermore, the large face lifting lug 140 and the small face lifting lug 150 are perpendicular to each other after installation, that is, the support shaft of the large face lifting lug 140 is parallel to the plane where the large pressure box surface 110 is located, and the support shaft of the small face lifting lug 150 is parallel to the plane where the small pressure box surface 120 is located, so as to facilitate crane lifting.

[0053] The large lifting lugs 140 of the same group are distributed on the same vertical plane of the box body 100. Two are set at the top and bottom of the two mounting surfaces 130, and a total of four large lifting lugs 140 are set as a group. The small lifting lugs 150 are also set on the same vertical plane of the box body 100, and a total of four are set. This design is to further ensure the stability during lifting.

[0054] The design of the large face lifting lug 140 and the small face lifting lug 150 not only provides the necessary mechanical strength and stability, but also significantly improves the safety, operational efficiency and service life of the entire multi-purpose iron press box, meeting the needs of industrial production for equipment reliability and efficiency.
