[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0028] See also Figure 1-Figure 4 A modular sand box includes a sand box body, the sand box body includes a base box 1 and a plurality of upper boxes 2 arranged above the base box 1. As one option, the shape and size of the base box 1 are adapted to the shape and size of the upper box 2.

[0029] The number and height of the upper box 2 can be specifically selected according to the casting requirements, such as Figure 1 As shown, only one upper box 2 is assembled on the base box 1. If it needs to be raised, it can be further stacked and assembled on the upper box.

[0030] Regarding the assembly method between the base box 1 and the upper box 2, and between the upper box 2 and another upper box, in this embodiment, a plurality of first mounting holes 11 are opened on the upper part of the base box 1, such as the first mounting holes 11 are opened evenly and circumferentially on the top panel 12 of the base box 1; a plurality of second mounting holes 21 are opened on the lower part of the upper box 2, such as the second mounting holes 21 are opened evenly and circumferentially on the bottom panel 22 of the upper box 2; a plurality of third mounting holes 23 are opened on the upper part of the upper box 2, such as the third mounting holes 23 are opened evenly and circumferentially on the top panel 24 of the upper box 2.

[0031] After aligning the first mounting hole 11 with the second mounting hole 21, the upper box 2 can be fixedly installed on the base box 1 by fasteners such as bolts; after aligning the third mounting hole 23 of the upper box 2 located at the bottom with the second mounting hole 21 of the upper box 2 located at the top, the two upper boxes can be fixedly assembled by fasteners such as bolts.

[0032] Of course, corresponding mounting holes may also be provided on the bottom panel 13 of the base box 1, and a corresponding base box or upper box may also be installed thereunder.

[0033] The structural layout of the base box 1 and the upper box 2 can be the same or similar. In this embodiment, a plurality of first heat sinks 14 are provided between the top panel 12 and the bottom panel 13 of the base box 1, and gaps are left between adjacent first heat sinks 14 to form cooling ports 3; a plurality of second heat sinks 25 are provided between the top panel 24 and the bottom panel 22 of the upper box 2, and gaps are left between adjacent second heat sinks 25 to form cooling ports 3.

[0034] As a further design solution, the first heat sink 14 and / or the second heat sink 25 are arranged upright, and a plurality of heat dissipation holes (not shown in the figure) are opened on the first heat sink 14 and / or the second heat sink 25 to further improve the heat dissipation effect.

[0035] A cement layer 4 is filled in the sand box body to cover the cooling port. Figure 1In the sand box of the style shown, a cement layer 4 is arranged inside the upper box 2 and the base box 1. The cement layer 4 has the same shape as the inner circle of the upper box 2 and the base box 1, and is annular. After the cement layer 4 is arranged, it covers all cooling ports 3 (including the cooling ports of the upper box and the cooling ports of the base box). As one of the options, Figure 2 As shown, the cement layer 4 is attached to the inner edges of the first heat sink 14 and the second heat sink 25 .

[0036] The design of the cooling port 3 can reduce or eliminate the gradual occurrence of cracks, pores and the like, and improve the gradual cooling speed. In the present application, there are also technical means that can further improve the above technical effects. Specifically, a plurality of cooling pipes 5 are arranged in the cement layer 4, such as Figure 2-4 As shown, the cooling pipe 5 can be first installed on the bottom panel of the upper box 2 or the base box 1, and then the cooling pipe can be embedded in the solidified cement layer 4 by cement pouring.

[0037] As for the arrangement direction of the cooling pipe 5 , as one option, one end of the cooling pipe 5 opens toward the inner side of the flask body, and the other end of the cooling pipe 5 opens toward the cooling port 3 .

[0038] In this embodiment, the bottom panels of the upper box 2 and the base box 1 can be designed to be relatively wide, with the inner half being used for arranging the cement layer 4 and the outer half being used for arranging the heat sink.

[0039] As one of the options, the outer wall of the flask body is assembled from iron plates, including corresponding bottom panels, heat sinks and top panels.

[0040] In order to further improve the overall strength and reduce the deformation of the sand box, in this embodiment, a reinforcing unit 6 is arranged inside the sand box body. Figure 2-4 As shown, the reinforcing unit 6 is also cast by cement, and includes a plurality of support heads 61, the outer ends of the support heads 61 abut against the inner wall of the cement layer 4. Of course, the reinforcing unit 6 and the cement layer 4 can also be cast simultaneously so that the two are connected as one. In this way, the outer end of the bracket 62 located inside the cement part of the reinforcing unit 6 can extend to the bracket 51 of the corresponding cooling pipe 5, so that the two are connected as one.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
