[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figures 1 to 4 As shown, a small-caliber high-pressure gate valve casting system according to an embodiment of the present invention comprises a frame 1; a plurality of springs 12 are fixedly connected to the top of the frame 1; a bearing plate 13 is fixedly connected to the top of the plurality of springs 12; a vibration motor 14 is fixedly connected to the bottom of the bearing plate 13; a mold plate 15 is placed on the top of the bearing plate 13; a sand box 16 is installed on the top of the mold plate 15; a horizontal runner 17 is provided on the top of the mold plate 15; an inner runner 18 is provided in the middle of the horizontal runner 17; when working, sand is filled into the interior of the sand box 16, and then the vibration motor 14 is started to drive The supporting plate 13 vibrates to make the sand material inside the sand box 16 vibrate evenly, and then the sand material is compacted. After completion, the mold plate 15 is taken out from the bottom of the sand box 16, and the two sand boxes 16 are combined. After completion, the molten metal is poured into the sand mold through the cross runner 17. The molten metal will enter the sand cavity along the cross runner 17 and the inner runner 18. After the sand cavity is filled with molten metal and the molten metal is cooled and solidified, the casting is completed. Through the above structure, when using sand mold casting, the impact of the molten metal on the sand material on the surface of the sand cavity can be reduced, and the occurrence of the situation where the quality of the casting is reduced due to the falling of the sand material can be reduced.

[0024] like Figures 1 to 3As shown, the top of the supporting plate 13 is fixed with a baffle 2; the middle part of the baffle 2 is rotatably connected to a screw 21; the middle part of the screw 21 is threadedly connected to a mounting block 22; both sides of the mounting block 22 are provided with a slot 23; the middle part of the slot 23 is detachably installed with a limit rod 24; during operation, after the mold plate 15 and the sand box 16 are placed on the supporting plate 13, the screw 21 is rotated to drive the mounting block 22 to move, and then drive the limit rod 24 to move toward the direction of the baffle 2, and the mold plate 15 and the sand box 16 are squeezed and fixed by the limit rod 24 and the baffle 2, so that the mold plate 15 and the sand box 16 can be tightly combined with the supporting plate 13, so that when the vibration motor 14 is started to drive the supporting plate 13 to vibrate, the vibration effect of the sand material caused by the sliding of the mold plate 15 and the sand box 16 is reduced, thereby reducing the occurrence of uneven sand filling and the decline in casting quality.

[0025] like Figures 1 to 3 As shown, a slide groove 3 is provided in the middle of the mounting block 22; a protective plate 31 is fixed to the side wall of the baffle 2; the protective plate 31 is slidably connected to the middle of the slide groove 3; during operation, when the sand is filled into the sand box 16 and the sand material is vibrated evenly, some of the sand material will fall to the outside of the sand box 16. At this time, the protective plate 31 will block the sand material, so that the sand material will not easily fall on the screw 21, thereby reducing the occurrence of the mounting block 22 getting stuck when moving along the screw 21.

[0026] like Figures 1 to 3 As shown, a slag discharge groove 4 is provided on the top of the supporting plate 13; the slag discharge groove 4 is located on one side of the screw 21; a plurality of brushes 41 are fixedly connected to the bottom of the limiting rod 24; during operation, some sand material will be scattered on the supporting plate 13. After a group of sand molds are compacted, the mold plate 15 and the sand box 16 will be removed from the supporting plate 13. At this time, the limiting rod 24 can be taken out from the card slot 23, and then the sand material remaining above the supporting plate 13 can be brushed off through the slag discharge groove 4, thereby reducing the occurrence of sand material remaining above the supporting plate 13, thereby reducing the impact of the sand material residue on the casting work.

[0027] like Figures 1 to 4 As shown, a collecting box 5 is slidably connected to the middle of the frame 1; the collecting box 5 is located below the slag discharge trough 4; during operation, the sand material brushed off through the slag discharge trough 4 will fall into the interior of the collecting box 5, thereby collecting the scattered sand material, making it easier to reuse the sand material later and improving the ease of use of the device.

[0028] like Figures 1 to 4As shown, the side wall of the frame 1 is rotatably connected to a baffle 6; the side wall of the frame 1 is fixed with a hook 61; during operation, after the collection box 5 is slid into the interior of the frame 1, the baffle 6 is rotated so that the bottom end of the baffle 6 limits the collection box 5, thereby reducing the collection box 5 from sliding out due to vibration. When the collection box 5 needs to be taken out, the baffle 6 is rotated so that the middle of the baffle 6 falls on the hook 61, thereby reducing the obstruction caused by the baffle 6 when the collection box 5 is taken out. Through the above structure, the collection box 5 can be reduced from sliding out due to vibration, and the sand material can be reduced from scattering on the ground.

[0029] like Figure 4 As shown, the bottom of the frame 1 is rotatably connected to a plurality of rotating rollers 7; the collecting box 5 is located above the plurality of rotating rollers 7; through the above structure, the sliding friction between the bottom of the collecting box 5 and the frame 1 can be converted into rolling friction, making the removal and installation of the collecting box 5 more labor-saving and improving the convenience of use of the device.
