Technical Field
[0001] The utility model relates to the technical field of casting sand boxes, in particular to a casting sand box for casting iron parts. Background Art
[0002] Sand casting is a common metal casting method that uses sand molds to create castings;
[0003] In the existing sand casting technology, a gate is generally left on the upper side of the upper box, and the upper box and the lower box are connected and fixed by bolts;
[0004] When pouring molten iron, due to the small diameter of the original gate, some of the molten iron will overflow out of the box, which is dangerous. In addition, before pouring, the upper box is usually placed directly on the lower box, which is not convenient for making the molds between the upper box and the lower box correspond at one time. Utility Model Content

[0006] The technical scheme adopted by the utility model is a casting sand box, comprising an upper box body and a lower box body, both sides of the upper box body are fixed with hinge shafts, the side surfaces of the hinge shafts are provided with limit ring grooves, a bent rod is rotatably connected in the limit ring groove, a leakage nozzle is provided between the opposite ends of the two bent rods, upper and lower sides of the upper and lower boxes are fixed with upper connecting plates and lower connecting plates, a plurality of fastening ribs are vertically fixed between the upper connecting plates and the lower connecting plates, a rotating handle is hingedly provided on the side surface of the fastening rib plate on one side of the lower box body, two lower clamping blocks and two upper clamping blocks are fixed on one side of the rotating handle, a plurality of limit slot holes are provided on the upper side of the upper connecting plate of the lower box body, and a limit boss is fixed in the limit slot hole on the lower side of the lower connecting plate of the upper box body.
[0007] As a further solution of the utility model: the limiting boss is inserted into the limiting slot hole so as to align the upper box body and the lower box body at one time.
[0008] As a further solution of the utility model: the distance between the upper clamping block and the lower clamping block is smaller than the sum of the thicknesses of the upper connecting plate and the lower connecting plate, so that the upper clamping block and the lower clamping block can clamp the upper connecting plate and the lower connecting plate.
[0009] As a further solution of the utility model: the lower side of the upper clamping block and the upper side of the lower clamping block are both arc surfaces, which are convenient for rotation and clamping.
[0010] As a further solution of the utility model: the nozzle is rotatably connected to the bent rod, so that the tip of the nozzle can be rotated downward.
[0011] As a further solution of the utility model: there are four limit slots in total, and the four limit slots are respectively located at the four corners of the upper connecting plate of the lower box body.
[0012] Compared with the prior art, the utility model has the following advantages: the utility model adds a nozzle structure, which can be used as an auxiliary function. By rotating the bent rod, the nozzle can be moved to the original pouring gate to facilitate the pouring of molten iron. The limiting slot hole and the limiting boss structure are added to facilitate the direct positioning of the upper box body. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.
[0021] The utility model provides a technical solution to solve the existing problems raised in the background technology.
[0022] Combined with Figure 1-4It can be known that the sand box includes an upper box body 1 and a lower box body 2, and hinge shafts 3 are fixed on both sides of the upper box body 1. A limit ring groove is provided on the side of the hinge shaft 3, and a bending rod 4 is rotatably connected in the limit ring groove. A leak nozzle 5 is provided between the opposite ends of the two bending rods 4 to facilitate auxiliary pouring of molten iron. Upper connecting plates 6 and lower connecting plates 7 are fixed on the upper and lower sides of the upper box body 1 and the lower box body 2. A plurality of fastening ribs 8 are vertically fixed between the upper connecting plate 6 and the lower connecting plate 7, which can play a fastening role. A rotating handle 9 is hinged on the side of the fastening rib 8 on one side of the lower box body 2. By pushing the rotating handle 9 upwards, the upper clamping block 9.2 and the lower clamping block 9.1 can be clamped on the outer sides of the upper connecting plate 6 and the lower connecting plate 7 for fixation. Two lower clamping blocks 9.1 and two upper clamping blocks 9.2 are fixed on one side of the rotating handle 9. A plurality of limiting slots 6.1 are provided on the upper side of the upper connecting plate 6 of the lower box body 2. A limiting boss 7.1 is fixed on the lower side of the lower connecting plate 7 of the upper box body 1 in the limiting slot 6.1.
[0023] The limiting boss 7.1 is inserted into the limiting slot 6.1 to facilitate the one-time alignment of the upper box body 1 and the lower box body 2; the distance between the upper clamping block 9.2 and the lower clamping block 9.1 is less than the sum of the thicknesses of the upper connecting plate 6 and the lower connecting plate 7, so that the upper clamping block 9.2 and the lower clamping block 9.1 can clamp the upper connecting plate 6 and the lower connecting plate 7; the lower side of the upper clamping block 9.2 and the upper side of the lower clamping block 9.1 are both arc surfaces, which are convenient for rotation and clamping; the nozzle 5 is rotationally connected to the bent rod 4, so that the tip of the nozzle 5 can be rotated downward; there are four limiting slots 6.1, and the four limiting slots 6.1 are respectively located at the four corners of the upper connecting plate 6 of the lower box body 2.
[0024] The working principle of the present application is as follows: before pouring, first align the compacted upper box body 1 with the lower box body 2, align the limiting boss 7.1 with the limiting slot 6.1, and then directly place the upper box body 1 on top of the lower box body 2, and then push the rotating handle 9 upwards to clamp the two lower clamping blocks 9.1 and the two upper clamping blocks 9.2 on the outer sides of the upper connecting plate 6 and the lower connecting plate 7 to tighten the distance between the upper box body 1 and the lower box body 2, and then rotate the bending rod 4 to adjust the position of the nozzle 5 so that the tip of the nozzle 5 faces the pouring gate, and then the molten iron can be poured through the nozzle 5.
[0025] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
