Abstract
Description
Technical Field
[0001] This utility model relates to the field of casting technology, specifically to a combined sand box for casting. Background Technology
[0002] In the casting production process, sand boxes are an indispensable tooling. A reasonable sand box structure and size play a significant role in obtaining high-quality castings and improving casting production efficiency. However, in actual casting processes, due to the diverse shapes, sizes, volumes, and lengths of the products being cast, to reduce sand box costs, a few fixed-model sand boxes are often used to cast various types of parts. Generally, a separate sand box is not manufactured for each part. This leads to the use of large sand boxes even for casting some small parts. To improve casting quality, many castings now use self-hardening resin sand. However, self-hardening resin sand is expensive. Using large sand boxes to cast small castings results in significant waste of self-hardening resin sand, increasing casting costs.
[0003] In addition, if the size of the casting is larger than the size of all the sand boxes in the factory, it is obvious that these existing sand boxes cannot meet the casting size of the large casting. If new sand boxes that meet this size are manufactured, not only will the cost be high, but after one or a few uses, there will be no new orders. These large sand boxes can only be placed in the sand box stacking area, which will not only waste resources, but also occupy factory space. Utility Model Content
[0004] This invention provides a modular sand box for casting. The sand box of this invention can be assembled into a sand box of the required size according to the size of the casting.
[0005] The technical solutions to the above technical problems are as follows:
[0006] Modular sand boxes for casting include:
[0007] The base consists of multiple bases.
[0008] Multiple first box panels, each first box panel has a first flange at both ends, a first mounting hole on the first box panel, and a second mounting hole on the first flange. When two adjacent first box panels are located on the base and these first box panels are arranged along the lateral direction of the base, the first flanges on the two adjacent first box panels are engaged.
[0009] The first bolt passes through the second mounting holes on two adjacent first flanges and then tightens the two first flanges.
[0010] Multiple second box panels, each of which has a second flange at both ends and a third mounting hole on the second flange. At least two second box panels are located on the base and these second box panels are arranged along the longitudinal direction of the base. The second box panels cooperate with the first box panel, and the third mounting hole corresponds to the first mounting hole.
[0011] The second bolt passes through the first mounting hole and the third mounting hole to fix the first box plate and the second flange.
[0012] The lid is supported by a first panel and / or a second panel.
[0013] Furthermore, the first box plate is provided with vent holes.
[0014] Furthermore, the lid is provided with a grille.
[0015] Furthermore, it also includes a column, a lower clamp, and an upper clamp. Columns are arranged on both sides of the first box plate. The lower clamp is located below the base and arranged along the longitudinal direction of the base. The two ends of the lower clamp are fixed to the column. The upper clamp is located above the box cover and arranged along the longitudinal direction of the box cover. After the two ends of the lower and upper clamps are fixed to the column, the column, the lower clamp, and the upper clamp hold the base, the first box plate, and the box cover tightly.
[0016] In this invention, the number of first box plates is selected according to the length of the casting. These first box plates are connected in series with first bolts and then fixed to the second box plates with second bolts to form a rectangular box. After the box body is fitted with the base and box cover, the clamping action of the uprights, lower clamps, and upper clamps makes the sand box a whole, strengthening the overall strength of the sand box and ensuring that the dimensions of the produced products are more stable and less prone to casting defects. Therefore, the sand box of this invention can be assembled according to the size of the casting to meet the casting requirements. Even without orders, the first and second box plates can be disassembled and stacked, reducing space occupation. Attached Figure Description

[0021] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0024] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0025] like Figures 1 to 3 As shown, the combined sand box for casting of this utility model includes a base 1, a first box plate 2, a first bolt 6, a second box plate 7, a second bolt 10, and a box cover 11. Each part and the relationship between them will be described in detail below.
[0026] In this utility model, there are multiple bases 1. In specific implementation, the number of bases 1 is selected according to the length of the casting, and multiple bases 1 are arranged sequentially along the same direction.
[0027] The number of first box plates 2 is multiple. In specific implementation, the number of first box plates 2 is selected according to the length of the casting. Each first box plate 2 has a first flange 3 at both ends, forming a 90° angle with the first box plate 2. The first box plate 2 has multiple first mounting holes 4, which are arranged in multiple rows, with at least two first mounting holes 4 in each row. This structure facilitates the adjustment of the sand box length as needed. The first flange 3 has a second mounting hole 5. When two adjacent first box plates 2 are located on the base 1 and arranged laterally along the base 1, the first flanges 3 on the adjacent first box plates 2 fit together.
[0028] The first box plate 2 is provided with a first reinforcing rib 2a, which helps to improve the strength of the first box plate 2. During the casting process, gas will inevitably be generated in the sand mold. After this gas diffuses through the sand mold into the sand box, if it cannot be discharged in time, it will affect the quality of the casting. Therefore, in this utility model, the first box plate 2 is provided with an exhaust hole 12, through which the gas generated during the casting process is discharged into the atmosphere.
[0029] After the first bolt 6 passes through the second mounting hole 5 on the two adjacent first flanges 3, it secures the two first flanges 3. The number of first box plates 2 is selected according to the length of the casting, and multiple first box plates 2 are connected in series.
[0030] There are multiple second box plates 7. In this embodiment, there are two second box plates 7, with one second box plate 7 arranged at each end of the multiple first box plates 2 connected in series. The second box plate 7 is provided with a second reinforcing rib 7a, which helps to improve the strength of the second box plate 7. Each second box plate 7 is provided with a second flange 8 at both ends, and the included angle between the second box plate 7 and the second flange 8 is 90°. The second flange 8 is provided with a third mounting hole 9. After at least two second box plates 7 are located on the base 1 and these second box plates 7 are arranged along the longitudinal direction of the base 1, the second box plates 7 cooperate with the first box plates 2, and the third mounting hole 9 corresponds to the first mounting hole 4. The second bolt 10 passes through the first mounting hole 4 and the third mounting hole 9 to fix the first box plate 2 and the second flange 8.
[0031] The box cover 11 is supported by the first box plate 2 and / or the second box plate 7. The box cover 11 is provided with a grid 13, which can increase the overall strength of the sand box.
[0032] This utility model also includes a column 14, a lower clamp 15, and an upper clamp 16. Columns 14 are arranged on both sides of the first box plate 2. The lower clamp 15 is located below the base 1 and arranged longitudinally along the base 1, with both ends of the lower clamp 15 fixed to the column 14. The upper clamp 16 is located above the box cover 11 and arranged longitudinally along the box cover 11. After both ends of the upper and lower clamps 16 are fixed to the column 14, the column 14, lower clamp 15, and upper clamp 16 tightly hold the base 1, the first box plate 2, and the box cover 11. The column 14 is preferentially fixed to the lower clamp 15 and the upper clamp 16 by bolts. The column 14, lower clamp 15, and upper clamp 16 make the sand box a whole, strengthening the overall strength of the sand box and ensuring more stable product dimensions and reducing the likelihood of casting defects.
