The structure of this embodiment includes an upper flask body 21 and a lower flask body 22. The upper end surface of the upper flask body 21 is provided with at least one grouting port 211. Providing multiple grouting ports 211 enables dispersed grouting, thereby ensuring uniform grouting. The upper flask body 21 and the lower flask body 22 are supported by a support base 11, support side panels 12, and a support top panel 13. The support side panels 12 are mounted on the left and right sides of the support base 11, and the support top panel 13 is mounted on the upper end surfaces of the support side panels 12.
[0023] See also Figure 1-Figure 3 、 Figure 5In this embodiment, the upper sand box body 21 is installed on the lower end surface of the support top plate 13 through the upper telescopic column 3, and the lower sand box body 22 is installed on the upper end surface of the support base 11 through the lower telescopic column 4. The number of the upper telescopic columns 3 is four, and the two upper telescopic columns 3 at one diagonal point are set to be electrically driven or hydraulically driven, and the two upper telescopic columns 3 at the other diagonal point are set to be unpowered; the number of the lower telescopic columns 4 is four, and the two lower telescopic columns 4 at one diagonal point are set to be electrically driven or hydraulically driven, and the two lower telescopic columns 4 at the other diagonal point are set to be unpowered, so as to ensure that the upper sand box body 21 and the lower sand box body 22 are powered when they move down or up, so that the force on each part is relatively uniform, and when the upper sand box body 21 and the lower sand box body 22 are in the closed state, the fit is relatively tight to avoid leakage.
[0024] See also Figure 1 、 Figure 2 and Figure 5 In this embodiment, a limiting assembly is provided at the corresponding position of the junction of the upper sand box body 21 and the lower sand box body 22. The limiting assembly includes upper limit blocks 51 installed on both sides of the upper sand box body 21, and an intermediate limit block 52 is provided in the middle of the inner side of the supporting side plate 12, and lower limit blocks 53 are installed on both sides of the lower sand box body 22. The lower end surface of the upper limit block 51 is set to an inclined shape, and the upper end surface of the lower limit block 53 is also set to an inclined shape. The intermediate limit block 52 is set to a triangular shape connected to the upper limit block 51 and the lower limit block 53. The upper limit block 51 stops when the inclined shape of the lower end surface and the upper end surface of the intermediate limit block 52 are just in contact, and the lower limit block 53 stops when the inclined shape of the upper end surface and the lower end surface of the intermediate limit block 52 are just in contact. During the process of combining the upper sand box body 21 and the lower sand box body 22, the upper limit blocks 51 on both sides of the upper sand box body 21 gradually move downward, and the lower limit blocks 53 installed on both sides of the lower sand box body 22 gradually move upward at the same speed or different speeds until the upper end faces of the upper limit blocks 51 and the middle limit blocks 52 are in contact with each other, and the lower end faces of the lower limit blocks 53 and the middle limit blocks 52 are in contact with each other. At this time, the lower end face of the upper sand box body 21 and the upper end face of the lower sand box body 22 are completely in contact with each other, thereby improving the accuracy of positioning.
[0025] See also Figure 1 and Figure 3 In this embodiment, an upper positioning plate 61 is provided on the periphery of the upper sand box body 21 at the connection on the other side, and positioning blocks 62 are arranged on the positioning plate. A lower positioning plate 71 is provided on the periphery of the lower sand box body 22 at the connection on the other side, and positioning grooves 72 are arranged on the lower positioning plate 71.
[0026] The principle and method of use of this embodiment: During the closing process of the upper sand box body 21 and the lower sand box body 22, the upper telescopic column 3 and the lower telescopic column 4 are started to extend, the upper sand box body 21 moves downward, the lower sand box body 22 moves upward, the upper limit blocks 51 on both sides of the upper sand box body 21 gradually move downward, and the lower limit blocks 53 installed on both sides of the lower sand box body 22 gradually move upward at the same speed or different speeds until the upper end faces of the upper limit blocks 51 and the middle limit blocks 52 are in contact with each other, and the lower limit blocks 53 and the middle limit blocks are in contact with each other. The lower end faces of the limit blocks 52 fit together, and each positioning block 62 gradually penetrates into each positioning groove 72. When the positioning block 62 and the positioning groove 72 are completely fitted together, the lower end face of the upper sand box body 21 and the upper end face of the lower sand box body 22 are completely fitted together. At this time, liquid is injected through the grouting port 211. After the casting is solidified, the upper telescopic column 3 and the lower telescopic column 4 are started to shorten, the upper sand box body 21 moves up, and the lower sand box body 22 moves down. The casting is taken out from the vacant space on the side where the positioning block 62 and the positioning groove 72 are set.
