[0031] Embodiment 1

[0032] Reference Figure 1 The utility model provides a sand box structure, including a sand box body 11 and a support structure 12. The support structure 12 is detachably connected to the bottom of the sand box body 11, and the support structure 12 can support the sand mold inside the sand box body 11.

[0033] Since the connection between the support structure 12 and the flask body 11 is a detachable connection, the support structure 12 can flexibly choose whether to be connected to the flask body 11 according to actual use needs;

[0034] When dealing with products with larger sizes and smaller sand holding capacity, the support structure 12 can be connected to the sand box body 11. At this time, the support structure 12 can support the sand mold inside the sand box body 11 to ensure that the sand mold does not disperse during the casting process and the molten iron does not escape. After the sand mold casting is completed, the sand mold can also be well kept from dispersing. On this basis, the sand box and the sand mold do not need to be transported by a trolley, which effectively reduces the cost of the molding line.

[0035] When dealing with products with simple shapes and large sand holding capacity, it has a good shaping effect. Such sand molds can be directly compacted by a compaction plate, and the sand molds can be kept from dispersing without the use of a supporting structure 12. Therefore, there is no need to connect the supporting structure 12 to the sand box body 11.

[0036] As an optional implementation, the support structure 12 includes support ribs 121, which are preferably made of steel bars and thus have good structural strength and the ability to resist deformation. A connecting hole 111 is provided on the sand box body 11, and the aperture of the connecting hole 111 matches the outer diameter of the support rib 121. Each support rib 121 can correspond to two connecting holes 111, and both ends of the support rib 121 are detachably connected to a connecting hole 111.

[0037] As an optional implementation, the number of the supporting ribs 121 is several, which can be flexibly selected according to actual use needs;

[0038] The total number of the connection holes 111 is preferably greater than twice the number of the support ribs 121. By setting this configuration, the number of the connection holes 111 on the sand box body 11 can be maximized in advance, so that the sand box body 11 has universality. When in use, the specific number of the support ribs 121 connected thereto can be selected according to actual use requirements;

[0039] Several support ribs 121 are crisscrossed horizontally and vertically to form a mesh. Such an arrangement can further enhance the support strength of the support structure 12. Although in a mesh shape, all the support ribs 121 are not connected to each other. The horizontally arranged support ribs 121 can be arranged on the same plane, and the longitudinally arranged support ribs 121 can be arranged on another plane. In addition, the opening positions of the connecting holes 111 need to be arranged accordingly.

[0040] As an optional implementation, the outer wall of the support rib 121 is provided with an external thread, and the inner wall of the connecting hole 111 is provided with an internal thread, so that the support rib 121 and the connecting hole 111 form a threaded connection. The threaded connection has good connection strength and is easier to disassemble and assemble, making the support rib 121 more convenient and quick to disassemble and assemble.

[0041] As an optional implementation, it also includes a locking nut. When the support structure 12 is selected, the support rib 121 is connected to the connecting hole 111, and the ends of the support rib 121 will pass through the connecting hole 111 to form a suspension. At this time, in order to further improve the connection strength and reduce movement during use, a locking nut is preferably used. After the end of the support rib 121 passes through the connecting hole 111, it is locked with the locking nut, which effectively reduces the movement and rotation of the support rib 121 and improves the structural stability. The structure of the locking nut itself is a relatively conventional prior art, so it will not be further described.

[0042] As an optional implementation, a plug is also included. When the support structure 12 is not used, the support rib 121 is not connected to the connecting hole 111. At this time, the connecting hole 111 is exposed, and the sand material is easy to leak from the connecting hole 111, polluting the environment. Therefore, by providing a plug, the connecting hole 111 can be sealed. The structure of the plug nut itself is a relatively conventional prior art, so it will not be further described.

[0043] Embodiment 2

[0044] Reference Figure 2 to Figure 3 The utility model also provides a sand box transfer system, including a lower sand box 1 and a sand box support track device 2, the lower sand box 1 is placed on the sand box support track device 2 and can move relative to the sand box support track device 2, and the lower sand box 1 includes the sand box structure mentioned in the above embodiment 1;

[0045] When dealing with products with larger sizes and smaller sand holding capacity, the support structure 12 can be connected to the sand box body 11 of the lower sand box 1. At this time, the support structure 12 can support the sand mold inside the sand box body 11 to ensure that the sand mold does not disperse during the casting process and the molten iron does not escape. Moreover, the sand mold can be well kept from dispersing after the sand casting is completed. On this basis, the sand box and the sand mold do not need to be transported by a trolley, but only need to rely on the sand box support track device 2 and move relatively with the assistance of the sand box support track device 2, which effectively reduces the cost of the molding line.

[0046] When dealing with products with simple shapes and large sand holding capacity, it has a good molding effect. Such sand molds can be directly compacted by a compacting plate, and the sand molds can be kept together without the use of a supporting structure 12. Therefore, there is no need to connect the supporting structure 12 to the sand box body 11 of the lower sand box 1. In this state, the sand box and the sand mold do not need to be transported by a trolley. They only need to rely on the sand box support track device 2 and move relative to each other with the assistance of the sand box support track device 2, thereby effectively reducing the cost of the molding line.

[0047] As an optional implementation, the sand box support rail device 2 includes a support frame 21 and support wheels 22. The support frame 21 is a frame body with a frame structure. The top of the support frame 21 includes two parallel walking beams 211. Each walking beam 211 is connected to a number of support wheels 22. Both sides of the sand box body 11 on the lower sand box 1 can be placed on the support wheels 22 and can move relative to each other with the assistance of the support wheels 22. This movement method is faster and has less friction, which is beneficial to extending the service life of the equipment.

[0048] As an optional embodiment, an upper sand box 3 is also included. The basic structure of the upper sand box 3 is basically similar to that of the lower sand box 1, except that the connecting hole 111 is not provided, and therefore there is no connection between the upper sand box 3 and the supporting structure 12. When moving on the molding line, the upper sand box 3 can be selectively placed on the sand box support track device 2 and can move relative to the sand box support track device 2, or the upper sand box 3 can be selectively placed on the lower sand box 1 and can follow the lower sand box 1 to move relative to the sand box support track device 2.

[0049] As an optional implementation, when the upper sand box 3 is placed on the lower sand box 1, the upper sand box 3 and the lower sand box 1 are connected by a locking hook mechanism 4, so that the upper sand box 3 and the lower sand box 1 are connected together and tightly. The structure of the locking hook mechanism 4 itself is a relatively conventional prior art, so it will not be further described.

[0050] The above are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
