[0002] In foundry production, a sand box is an important tooling. During molding, the pattern is placed on the molding plate, the sand box is put on, molding sand is placed in the sand box and vibrated tightly. The molding sand reacts with the resin curing agent in the sand box to bond the molding sand together to form a sand mold. When it reaches a certain strength, the sand box is separated from the pattern, and a cavity for the required casting is formed in the sand box.
[0003] At present, the sand box structure is mainly made by welding. A square frame is formed by welding steel plates around. Straps are welded on the sand box to prevent the sand box from deforming during use. Such sand boxes have stability, but their usability and replaceability are poor. They are suitable for the production of small varieties in large quantities. However, with the flexible transformation of production enterprises, the product types tend to be small batches and multiple varieties. For foundry enterprises producing single-piece small batches, the sizes and structures of the parts to be cast are different. Therefore, sand boxes of different sizes need to be made according to different products, and each product requires a welded and fixed sand box. On the one hand, it increases the input cost of production materials, and on the other hand, it results in low utilization rate of sand boxes, occupying funds and storage space. Summary of the Utility Model

[0022] The working principle and beneficial effects of the present utility model are as follows:
[0023] In the present utility model, to solve the problem that traditional sand boxes cannot meet the requirements of single-piece and small-batch production, some foundry enterprises make several sand boxes with fixed large sizes for production. However, this will increase the amount of sand used in molding production, still leading to an increase in production costs. Moreover, for the gating systems and riser positions of different casting parts, they are all different. Borrowing sand boxes will cause interference between the ribbands and the risers and gating systems. During production, the interfering ribbands need to be removed, which easily causes the molding sand mold to bulge and affect the product quality.
[0024] Therefore, instead of the traditional fixed-form sand box, a detachable and reconfigurable sand box structure is provided to achieve the function of adjustable dimensions, which can be applicable to the production of casting parts with different structures and sizes.

[0025] Specifically, the entire sand box is formed by sequentially and detachably connecting several standard bodies and several connecting bodies end to end. The detachable form can be achieved in various ways, as long as it ensures that the formed area that can shape the workpiece can be surrounded between each component, and it can stably support the sand. Specifically, the wedge principle can be used to clamp each connected standard body and connecting body, or threaded connection forms such as fasteners can be used to clamp each connected standard body and connecting body, or a riveting structure can be used to rivet the standard body and the connecting body together.
[0026] This can only achieve the function of rapid assembly. In order to achieve the function of adjusting dimensions, it is necessary to further provide connection holes or connection positions at different positions on the connecting body and the standard body to change the specific connection position between the two, so as to achieve the purpose of adjusting dimensions.
[0027] More specifically, the entire standard body and the connecting body are both composed of steel structures, etc., with a regular overall shape, which is rectangular or has a certain bending angle to form the formed area.
[0028] Compared with the traditional welded sand box, the entire adjustable sand box has the characteristics of less investment in sand boxes and high utilization rate. It can avoid the need to weld special sand boxes for each product, and can also avoid the disadvantages of a large amount of molding sand used and high production costs when borrowing sand boxes for molding.

In this article, "one" not only means "only this one", but also can mean "more than one" situation, and "several" includes "two" and "more than two".
[0038] In this article, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0039] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.
[0040] Refer to Figures 1 to 5, which is the first embodiment of the present utility model, proposes an adjustable sand box, including: a plurality of standard bodies 1 and a plurality of connecting bodies 2. The plurality of standard bodies 1 and the plurality of connecting bodies 2 are sequentially connected end to end alternately. The standard body 1 and the connecting body 2 are detachably connected, and the plurality of standard bodies 1 and the plurality of connecting bodies 2 enclose a forming area 3.
[0041] In this embodiment, as Figure 1 shown, to solve the problem that traditional sand boxes cannot meet the requirements of single-piece and small-batch production, some foundry enterprises will make several fixed large-sized sand boxes for production. However, this will increase the amount of sand used in molding production, still resulting in an increase in production costs. Moreover, the gating systems and riser positions of different casting parts are different. Borrowing sand boxes will cause interference between the box straps and the risers and gating systems. During production, it is necessary to remove the interfering box straps, which is likely to cause the molding sand mold to bulge and affect the product quality.
[0042] Therefore, instead of the traditional fixed-form sand box, a detachable and reconfigurable sand box structure is provided to achieve the function of adjustable size, which can be applied to the production of casting parts with different structures and sizes. That is, it can reduce the capital investment in fixed sand boxes and avoid the increase in production costs caused by the increase in sand volume during the production process.
[0043] Specifically, the entire sand box is formed by sequentially and alternately connecting a plurality of standard bodies 1 and a plurality of connecting bodies 2 in a detachable manner. The detachable form can be realized in various forms, as long as it is ensured that the formed area 3 that can form the workpiece can be enclosed between each component, and it is ensured that the sand can be stably supported. The detachable form can specifically use the wedge principle to clamp each connected standard body 1 and connecting body 2, or use threaded connection forms such as fasteners 4 to clamp each connected standard body 1 and connecting body 2, or use a riveting structure to rivet the standard body 1 and the connecting body 2 together.
[0044] This can only achieve the function of rapid assembly. In order to achieve the function of adjusting the size, it is further necessary to open connection holes or connection positions at different positions on the connecting body 2 and the standard body 1 to change the specific connection positions of the two, so as to achieve the purpose of adjusting the size.
[0045] More specifically, the entire standard body 1 and the connecting body 2 are both composed of steel structures, etc., and the overall shape is regular, being rectangular or having a certain bending angle to form the forming area 3.
[0046] Compared with the traditional welded sand box, the entire adjustable sand box has the characteristics of less investment in the sand box and high utilization rate. It can avoid the need to weld a special sand box for each product, and can also avoid the disadvantages of a large amount of molding sand used and high production costs when borrowing sand boxes for molding.
[0047] Furthermore, the connecting body 2 has a first strip-shaped hole 201, and the standard body 1 has a plurality of positioning holes 101. The plurality of positioning holes 101 are arranged in sequence along the length direction of the first strip-shaped hole 201. Further included is a fastener 4 that passes through the positioning hole 101 and the first strip-shaped hole 201 for connecting the connecting body 2 and the standard body 1.
[0048] In this embodiment, as Figure 1 shown, specifically, the standard body 1 is the edge part of the sand box, and the connecting body 2 is the corner part of the sand box. A threaded connection form such as the fastener 4 is used to complete the connection condition between the standard body 1 and the connecting body 2. However, if connection holes are opened at different positions on both of them, problems such as the connection holes not corresponding or being difficult to correspond during installation and assembly may occur. Therefore, the connecting body 2 for connecting two edge positions of the sand box at the corner position 202 is provided with a first strip-shaped hole 201, and a plurality of positioning holes 101 for connection are opened on the standard body 1. And for facilitating adaptation to different installation positions, the plurality of positioning holes 101 are arranged along the length direction of the first strip-shaped hole 201. During connection, it is possible to quickly determine that the positioning hole 101 to be connected overlaps and communicates with the first strip-shaped hole 201. Finally, the two are clamped tightly through the threaded connection of the fastener 4 to complete the assembly of the adjustable sand box, and no vibration will occur during use, nor will the fastener 4 become loose.
[0049] Furthermore, the standard body 1 is in a straight plate shape, and both ends of the standard body 1 have a plurality of positioning holes 101. The connecting body 2 is in an L shape, and both ends of the connecting body 2 have a first strip-shaped hole 201. The first strip-shaped holes 201 at both ends of the connecting body 2 respectively communicate with the positioning holes 101 of the two standard bodies 1.
[0050] Furthermore, both the standard body 1 and the connecting body 2 are four in number.
[0051] Furthermore, the connecting body 2 also has a corner position 202. Further included is a reinforcing rib 5, and the reinforcing rib 5 is arranged at the corner position 202.
[0052] In this embodiment, as Figure 1As shown, the sand box structure is usually regular. Therefore, the standard main body 1 at the edge part is in the shape of a straight plate, and the connecting main body 2 at the corner part is in the shape of an L, which is convenient for forming a rectangular and regular forming area 3. Specifically, a number of positioning holes 101 are provided at both ends of the standard main body 1, which are convenient for connecting with the strip holes 201 of the connecting main body 2 at the corner positions 202 at both ends. Similarly, for the connecting main body 2, strip holes 201 are opened at both ends. Further, since the whole sand box has a certain height, to improve the connection stability, a number of groups of positioning holes 101 and strip holes 201 can be further opened along the height direction of the sand box. The specific arrangement form can be to evenly distribute 3 rows of positioning round holes with a diameter of 22 mm within 200 mm at both ends of the standard main body 1, with 4 in each row and a spacing of 50 mm for M20 bolt assembly. The strip holes 201 at both ends of the connecting main body 2 are 22 mm in height and 100 mm in length, and a reinforcing rib 5 is welded at the L-shaped corner position 202 to improve the overall structural stability, and four groups of standard main bodies 1 and connecting main bodies 2 are used.
[0053] Further, the cross-section of the standard main body 1 is in the shape of a concave character. The standard main body 1 has an installation through groove 102, and a number of positioning holes 101 are provided at both ends of the installation through groove 102. One end of the connecting main body 2 is located in the installation through groove 102.
[0054] In this embodiment, as Figures 1 to 4 shown, since both ends of the L-shaped connecting main body 2 are connected to the standard main body 1 through the strip holes 201, in order to smoothly complete the corresponding action with the strip holes 201 for the positioning holes 101 at different positions, an installation through groove 102 for one end of the connecting main body 2 to slide on is opened on the standard main body 1. Specifically, the overall cross-section of the standard main body 1 is in the shape of a concave character. During installation and assembly, the position of the connecting main body 2 can be placed first. Through one end of it being located in the installation through groove 102 and its width being equal to the width of the installation through groove 102, which allows for stable sliding on the standard main body 1, a certain positioning hole 101 is determined to correspond to the strip hole 201, and the threaded connection of the fastener 4 is realized.
[0055] Further, two of the relatively arranged standard main bodies 1 are reinforcing main bodies 6, and the other two relatively arranged standard main bodies 1 are hoisting main bodies 7. It also includes: an installation block 8, which is arranged on the reinforcing main body 6; a reinforcing rod 9, which is arranged on the installation block 8. The reinforcing rod 9 has a strip hole 901. The reinforcing rods 9 on the two reinforcing main bodies 6 are arranged in a staggered manner and are in mutual contact, and the two strip holes 901 are in communication with each other.
[0056] Further, there are a number of installation blocks 8, and the number of installation blocks 8 is arranged along the length direction of the reinforcing main body 6.
[0057] In this embodiment, as Figures 1 to 5As shown in the figure, in order to enhance the strength of the sand box and prevent the sand box from bulging and deforming due to the buoyancy and gravity of molten steel during the pouring process, which may affect the dimensional deformation of the workpiece, "box belts", namely mounting blocks 8 and reinforcing rods 9, are additionally installed on the adjustable sand box. Specifically, they should act on the opposite standard bodies 1 instead of the connecting bodies 2 to maximize the effect. Therefore, two opposite standard bodies 1 are set as the reinforcing bodies 6, and the other two opposite standard bodies 1 are set as the lifting bodies 7 to facilitate subsequent position movement.
[0058] A row of mounting blocks 8 are welded to the two reinforcing bodies 6 at intervals along the length of the reinforcing body 6. A reinforcing rod 9 is installed on each mounting block 8 through bolts. A set of opposite reinforcing rods 9 are connected to achieve the above functions. Therefore, the connection form of fasteners 4 such as bolts is still adopted. However, since the overall size of the sand box is adjustable, and to avoid the situation that the opposite reinforcing rods 9 cannot adapt to the adjustment after adjustment, or still need to face a number of corresponding positioning holes 101, a strip-shaped hole two 901 is opened on the reinforcing rod 9. The two are offset and abutted against each other and connected to each other, and finally connected by bolts. Specifically, a 22mm positioning round hole is used at one end to be fixed to the mounting block 8 on the reinforcing body 6, and a strip-shaped hole two 901 is used at the other end. The two reinforcing rods 9 overlap at the strip-shaped hole two 901, and bolts are inserted and fixed at the overlapping part.
[0059] Furthermore, it further includes: a lifting column 10, and the lifting column 10 is arranged on the lifting body 7.
[0060] Furthermore, there are four lifting columns 10, and two lifting columns 10 are symmetrically arranged on one lifting body 7.
[0061] In this embodiment, as Figure 1 、 3 shown, the lifting columns are welded to the lifting body 7, and two groups of lifting columns 10 are symmetrically welded on the opposite lifting bodies 7, which is convenient for lifting, improves the lifting stability, and improves the overall practicality.
[0062] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
