Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] like Figure 1 to Figure 4 As shown, the present embodiment proposes a casting sand box, comprising a sand box 1, a sand box 2 is provided at the bottom of the sand box 1, plate bodies 3 are fixedly installed on both sides of the outside of the sand box 1, blocks 4 are fixedly connected to the outsides of the two plate bodies 3, rod bodies 5 are fixedly connected to the insides of the two blocks 4, positioning rods 6 are fixedly connected to the bottoms of the two rod bodies 5, plate bodies 7 are fixedly installed on both sides of the outside of the sand box 2, connecting shells 8 are fixedly connected to one side of the outsides of the two plate bodies 27, springs 9 are fixedly connected to the bottoms of the inner cavities of the two connecting shells 8, slide plates 10 are fixedly connected to the tops of the two springs 9, and force plates 11 are fixedly connected to the tops of the two slide plates 10, shells 12 are fixedly connected to both sides of the outside of the sand box 2, elastic springs 13 are fixedly connected to one side wall of the inner cavities of the two shells 12, sliders 14 are fixedly connected to one end of the two elastic springs 13, and clamping plates 15 are fixedly connected to one side of the outsides of the two sliders 14.

[0029] In this embodiment, the bottom of the sand box 1 is in contact with the top of the sand box 2, and the positioning rod 6 is configured to be a zigzag shape.

[0030] In this embodiment, the outer surfaces of the two slide plates 10 are respectively slidably connected to the inside of the two connection shells 8 , and the top of the force-bearing plate 11 is in contact with the bottom of the positioning rod 6 , which can facilitate the sliding operation of the slide plates 10 .

[0031] In this embodiment, the housing 12 is located on one side outside the plate body 7 , and the outer surface of the slider 14 is in contact with the inside of the housing 12 , which can facilitate the sliding of the slider 14 inside the housing 12 .

[0032] In this embodiment, the bottom of the clamping plate 15 contacts the top of the positioning rod 6 , and a pull rod 16 is fixedly connected to one side of the outside of the sliding block 14 , so that the pull rod 16 can drive the sliding block 14 to move.

[0033] In this embodiment, the cross section of the pull rod 16 is set to be L-shaped, and the pull rod 16 extends to the outside of the shell 12, which can facilitate the movement of the pull rod 16.

[0034] During use, when the sand box 1 and the sand box 2 need to be combined, the staff first needs to place the sand box 2 on the ground, and then place the sand box 1 on the top of the sand box 2. During this process, the sand box 1 will synchronously drive the plate 1 to move downward, and the plate 1 will synchronously drive the block 4, the rod 5 and the positioning rod 6 to move during the movement. The positioning rod 6 will gradually contact the clamping plate 15 during the movement. When the positioning rod 6 slides over the outer surface of the clamping plate 15, the clamping plate 15 will be forced to drive the slider 14 to move forward. During the sliding process, the slider 14 will synchronously drive the elastic spring 13 to perform compression work, and the positioning rod 6 will synchronously drive the slide plate 10 to move downward during the process of sinking and contacting the force plate 11. The slide plate 10 will synchronously drive the spring 9 to perform compression work during the movement, so that after the positioning rod 6 slides over the outside of the clamping plate 15, the spring 9 drives the slide plate 10 and the force plate 11 to move upward through rebound, and then a fixed structure is formed between the positioning rod 6 and the clamping plate 15 to facilitate the assembly work between the sand box 1 and the sand box 2.

[0035] Example 2

[0036] like Figure 1 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that two plate bodies 17 are fixedly installed on both sides of the outside of the sand box 1, and the outsides of the four plate bodies 17 are fixedly connected with a card shell 18, which can facilitate the fixed connection of the card shell 18.

[0037] In this embodiment, pulleys 19 are provided inside the four jamming shells 18 , and the pulleys 19 are movably connected to the jamming shells 18 via a rotating shaft, which can facilitate the connection and rotation of the pulleys 19 .

[0038] In this embodiment, both sides of the outside of the sand box 2 are fixedly connected with plate bodies 20, and the outsides of the four plate bodies 20 are fixedly connected with fixing blocks 21, which can facilitate the fixed connection of the plate bodies 20.

[0039] In this embodiment, the shape of the fixing block 21 is set to be U-shaped, and an anti-skid layer is provided on the outside of the fixing block 21 to facilitate the anti-skid work of the fixing block 21.

[0040] When in use, when it is necessary to separate the sand box 1 from the sand box 2, the staff needs to lay down the sand box 1 and the sand box 2, that is, the pulley 19 and the fixed block 21 are in contact with the ground. Then the staff needs to pull the pull rod 16. The pull rod 16 will synchronously drive the slider 14 to move during the pulling process, and the slider 14 will synchronously drive the clamping plate 15 to move during the movement. In this process, the elastic spring 13 will be compressed. When the clamping plate 15 leaves the outside of the positioning rod 6, the spring 9 will rebound quickly. During the rebound process, the spring 9 will synchronously drive the slide plate 10 and the force plate 11 to push the positioning rod 6 to the outside. During the pushing process, the positioning rod 6 will synchronously drive the rod body 5, the block body 4 and the plate body 13 to move. During the movement process, the plate body 13 will synchronously drive the sand box 1 to separate from the sand box 2 2. At the same time, the plate body 3 17 will drive the card shell 18 to move and the pulley 19 to slide, so as to facilitate the separation of the two.
