Description

Technical Field

[0001] This utility model relates to the field of sand box casting technology, specifically a sand box that can be quickly assembled. Background Technology

[0002] A sand mold is a casting mold in which the structural shape of the part is made in advance using other easily formable materials. The mold is then placed in a sand mold, thus forming a cavity in the sand mold that is the same size as the part structure. A fluid liquid is then poured into this cavity. Sand and binder are usually used to make the sand mold. The making of the mold usually includes one or more cavities to form the shape of the casting.

[0003] Patent CN210280593U discloses a sandbox, comprising an upper box and a lower box. An upper ear plate is provided on each side of the upper box, and a lower ear plate is provided on each side of the lower box. A rectangular positioning post is fixed on one upper ear plate, and a circular positioning post is fixed on the other upper ear plate. Rectangular and circular positioning holes, respectively, are provided on the two lower ear plates to mate with the rectangular and circular positioning posts. This invention, through structural improvements, results in uneven wear on the two pairs of positioning posts and holes, thus limiting the movement of the upper box in the plane and reducing errors.

[0004] Based on existing solutions and practical applications, current sandboxes still have some problems. For example, when using existing sandboxes, since the sandbox is composed of two boxes, it takes more time to assemble and splice them, making assembly more troublesome and reducing the flexibility of use. At the same time, when installing the two boxes, positioning and alignment of the two boxes becomes difficult, which not only affects the overall installation accuracy but also increases the installation time. Furthermore, they are prone to deformation or collapse when subjected to external forces or heavy loads during use. Utility Model Content

[0005] The purpose of this utility model is to provide a sand box that can be quickly assembled, in order to solve the problems mentioned in the background art. Currently, when assembling the upper and lower boxes, more time is required for assembly, making the assembly process more troublesome and reducing the flexibility of use. At the same time, it also makes it difficult to position and align the upper and lower boxes during installation, which not only affects the overall installation accuracy but also leads to longer installation time. Furthermore, it is prone to deformation or collapse when subjected to external forces or heavy loads during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sand box that can be quickly assembled, comprising:

[0007] The lower box is above which the upper box is placed;

[0008] Also includes:

[0009] The positioning pin holes are fixedly installed on the side wall of the lower housing, and the positioning pin holes are symmetrically arranged about the vertical central axis of the lower housing. The positioning pin holes are also symmetrically arranged about the front and back about the vertical central axis of the lower housing. Guide rods are fixedly installed at both the front and back ends of the upper housing, and the guide rods are symmetrically arranged about the vertical central axis of the upper housing. First mounting plates are fixedly installed at both the left and right ends of the upper housing, and fixed rods are rotatably connected to both the front and back ends of the first mounting plates.

[0010] The second mounting plate is fixedly installed on the side wall of the lower housing and is symmetrically arranged about the vertical central axis of the lower housing. The front and rear ends of the second mounting plate are fixedly installed with fixing slots. A sliding cavity is fixedly installed on the plate body of the second mounting plate, and the front and rear ends of the sliding cavity are slidably connected with limit rods. The front and rear ends of the sliding cavity are fixedly installed with first springs, and one end of the first spring is fixedly connected to the limit rod.

[0011] Preferably, the guide rod is arranged in a corresponding state with the positioning pin hole, and the rod body of the guide rod extends through to the lower end of the positioning pin hole.

[0012] Preferably, the fixing slot is arranged in a "U" shape, and through holes are opened at both ends of the fixing slot. The fixing slot and the rod body are arranged in a corresponding state, and the size of the inner cavity of the fixing slot is the same as the size of the rod body. The lower end of the fixing rod body is also provided with a through hole.

[0013] Preferably, the length of the limiting rod is half the length of the sliding cavity, and the limiting rod is set in a corresponding state with the through hole on the fixed slot, and the limiting rod passes through the fixed slot.

[0014] Preferably, both the front and rear ends of the lower box and the upper box are fixedly installed with sliding grooves, and the sliding grooves in the lower box and the upper box are slidably connected together by a reinforcing plate, and the upper and lower ends of the reinforcing plate are provided with limit holes.

[0015] Preferably, a sliding rod is fixedly installed at the middle position of the slide groove, and a stop rod is slidably connected to the body of the sliding rod. A second spring is sleeved and connected to the outside of the sliding rod body, and the second spring is fixedly connected to the stop rod.

[0016] Preferably, the rod body of the stop rod is configured to correspond to the limiting hole on the reinforcing plate, and the rod body of the stop rod passes through the reinforcing plate and is engaged with the slide groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the quick-assembly sand box shortens the assembly time by quickly assembling the upper and lower boxes, thereby improving work efficiency. At the same time, the guide simplifies the installation process, making the upper and lower boxes more accurately aligned and connected, shortening the installation time and reducing installation errors. Furthermore, the reinforcement significantly improves the overall strength and stability of the box, enabling it to withstand greater pressure and external impacts, making it less prone to deformation and damage.

[0018] 1. The device comprises a lower housing, an upper housing, a first mounting plate, a fixing rod, a fixing slot, a sliding cavity, a limiting rod, and a first spring. By pulling the limiting rods at both ends of the sliding cavity, the limiting rods compress the first spring inside the sliding cavity. Then, by flipping the fixing rod on the first mounting plate, which is aligned with the fixing slot in a U-shape, the lower end of the fixing rod is placed within the slot. Since the lower end of the fixing rod and both ends of the fixing slot have through holes, the fixing of the limiting rod is released. The spring force of the first spring causes the limiting rod to reset. Because the limiting rod is aligned with the limiting hole on the fixing slot, the spring force of the first spring causes the limiting rod to eject through the fixing rod and the fixing slot, thus connecting the lower and upper housings together. This allows for quick assembly, shortening assembly time and improving work efficiency.

[0019] 2. It is equipped with a lower housing, an upper housing, positioning pin holes, and guide rods. The positioning pin holes at the front and rear ends of the lower housing correspond to the guide rods at the front and rear ends of the upper housing. This allows the guide rods to be inserted into the positioning pin holes and extend through to the lower end of the positioning pin holes during the assembly of the lower and upper housings. The cooperation between the positioning pin holes and the guide rods guides the assembly of the lower and upper housings, simplifying the installation process, making the two housings more accurately aligned and connected, shortening the installation time, and reducing installation errors.

[0020] 3. The enclosure is equipped with a lower housing, an upper housing, a sliding groove, a reinforcing plate, a sliding rod, a stop rod, and a second spring. Sliding grooves are fixedly installed at both the front and rear ends of the lower and upper housings. A sliding rod is fixedly installed at the middle of each sliding groove. Pulling the stop rod causes it to slide along the sliding rod, compressing the second spring on the sliding rod. The reinforcing plate then slides along the sliding groove, connecting the sliding grooves in the lower and upper housings. Limit holes are provided at both the top and bottom of the reinforcing plate, and through holes in the reinforcing plate corresponding to the stop rod. This allows the spring force of the second spring to reset the stop rod, causing it to retract through the reinforcing plate and engage with the sliding groove, thus reinforcing the lower and upper housings. This reinforcement significantly improves the overall strength and stability of the enclosure, enabling it to withstand greater pressure and external impacts, and reducing the risk of deformation or damage.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5This utility model provides a technical solution: a sand box that can be quickly assembled, comprising: a lower box body 1, an upper box body 2, a positioning pin hole 3, a guide rod 4, a first mounting plate 5, a fixing rod 6, a second mounting plate 7, a fixing slot 8, a sliding cavity 9, a limiting rod 10, a first spring 11, a sliding groove 12, a reinforcing plate 13, a sliding rod 14, a stop rod 15, and a second spring 16.

[0029] First, as attached Figure 1 Appendix Figure 2 and attached Figure 3 As shown, when the lower box 1 and the upper box 2 are spliced ​​together, since the side wall of the lower box 1 is fixedly equipped with two sets of positioning pin holes 3, and the upper box 2 is also fixed with two sets of guide rods 4 at both the front and rear ends, when the upper box 2 and the lower box 1 are spliced ​​together, the guide rods 4 on the upper box 2 are aligned with the positioning pin holes 3 on the lower box 1. Since the positioning pin holes 3 and the guide rods 4 are set in a corresponding state, the guide rods 4 are inserted into the interior of the positioning pin holes 3. After the guide rods 4 are placed inside the positioning pin holes 3, the upper box 2 is slowly pressed down, so that the guide rods 4 extend through to the lower end of the positioning pin holes 3, and the upper box 2 is placed above the lower box 1, so that the upper box 2 and the lower box 1 are aligned, thereby simplifying the installation process and making the lower box 1 and the upper box 2 more accurately aligned, shortening the alignment time and reducing the errors caused by splicing.

[0030] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4As shown, when the upper housing 2 is positioned above the lower housing 1 through the cooperation between the positioning pin hole 3 and the guide rod 4, the upper housing 2 is fixedly mounted with first mounting plates 5 at both ends, and fixed rods 6 are rotatably connected to the front and rear ends of the first mounting plates 5. Then, the lower housing 1 is fixedly mounted with second mounting plates 7 at both ends, and fixed slots 8 are fixedly mounted to the front and rear ends of the second mounting plates 7. A sliding cavity 9 is also fixedly mounted on the second mounting plates 7. Since limit rods 10 are slidably connected to the front and rear ends of the sliding cavity 9, pulling the limit rods 10 compresses the first spring 11 inside the sliding cavity 9. Because the fixed slots 8 are U-shaped, and the rods 6 are connected to the fixed slots... The 8 are set in a corresponding state. Then, the size of the cavity of the fixed slot 8 is consistent with the size of the fixed rod 6. The fixed rod 6 is placed in the slot of the fixed slot 8 by flipping it over. At the same time, through holes are opened at the lower end of the fixed rod 6 and the front and rear ends of the fixed slot 8. Since the limiting rod 10 is set in a corresponding state with the through holes on the fixed slot 8, the fixing of the limiting rod 10 is released. The elastic force of the first spring 11 drives the limiting rod 10 to reset and causes the limiting rod 10 to eject through the fixed slot 8 and the fixed rod 6. Thus, the fixed slot 8 and the fixed rod 6 are fixedly connected together by the limiting rod 10, so as to fix the lower box 1 and the upper box 2. This makes it faster to assemble the lower box 1 and the upper box 2, thereby shortening the assembly time.

[0031] As attached Figure 1 Appendix Figure 3 and attached Figure 5 As shown, after the lower box 1 and the upper box 2 are assembled, sliding grooves 12 are fixedly installed at both the front and rear ends of the lower box 1 and the upper box 2. A sliding rod 14 is also fixedly installed at the middle position of the sliding grooves 12, allowing the stop rod 15 to slide on the sliding rod 14. When the stop rod 15 slides on the sliding rod 14, it simultaneously compresses the second spring 16, thereby slidably connecting the reinforcing plate 13 to the sliding grooves 12. This connects the sliding grooves 12 in the lower box 1 and the upper box 2 together through the reinforcing plate 13. Since the upper and lower ends of the reinforcing plate 13 are provided with limit holes, the fixing of the stop rod 15 is loosened. Then, the spring force of the second spring 16 drives the stop rod 15 to reset, so that the stop rod 15 slides on the body of the sliding rod 14 and the stop rod 15 is ejected through the reinforcing plate 13 and engaged with the slide groove 12. Thus, through the cooperation between the slide groove 12 and the reinforcing plate 13, the lower box 1 and the upper box 2 can be reinforced, which can significantly improve the overall strength and stability, and thus be able to withstand greater pressure and external impact, and is not easily deformed or damaged.
