Description

Technical Field

[0001] This utility model belongs to the field of sand box technology, and in particular relates to a sand box with multi-level height adjustment and rib plate position adjustment. Background Technology

[0002] In casting, the sand mold is a key tool in sand casting. Its main functions are to fix and support the sand mold, preventing it from deforming or collapsing due to external forces during handling, turning, or storage, thus ensuring the integrity of the mold cavity. By controlling the relative positions of the upper and lower sand molds, it ensures the accuracy of mold assembly and avoids misalignment, thereby ensuring the dimensional accuracy of the casting. It can withstand the impact and static pressure of high-temperature molten metal, preventing the sand mold from being broken and causing fire. At the same time, it facilitates the handling and turning of sand molds with equipment, greatly improving production efficiency and having an important impact on casting quality and production stability.

[0003] Traditional sand boxes typically employ a rigid frame structure of fixed height, assembled by bolts or welding. The interior of the sand box relies on ribs in fixed positions for support. However, when facing casting requirements of different heights, different models of sand boxes need to be replaced, which not only reduces production efficiency but also requires the storage of a large number of sand boxes of various specifications, resulting in resource waste.

[0004] To address these issues, we provide a sandbox with multi-level height adjustment and rib plate position adjustment. Utility Model Content

[0005] The purpose of this utility model is to provide a sandbox with multi-level height adjustment and rib plate position adjustment. The height adjustment is achieved through the sliding cooperation between the outer frame and the inner frame and the multi-level positioning structure. At the same time, the position adjustment is achieved by the sliding of the rib plate along the groove. This solves the problems of existing sandboxes with fixed height requiring frequent replacement of sandboxes of different specifications and poor applicability due to the non-adjustable position of the rib plate.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a sandbox with multi-level height adjustment and rib plate position adjustment, including a enclosure and an outer frame. An inner frame is movably fitted inside the outer frame. Two parallel first slots are opened on each of the four sides of the outer frame. Two fixing blocks are fixedly connected to each of the four sides of the inner frame and are respectively slidably connected inside the corresponding first slots. A vertically downward fixing frame is fixedly connected to the center of each of the four sides of the outer frame, and positioning holes are equidistantly opened in the interior of the fixing frame along the vertical direction. A sleeve is movably fitted to the outside of the outer frame and the four fixing frames, and the sleeve is fixedly connected to the outside of the fixing block by bolts. A hand-tightening bolt that matches the positioning hole is rotatably connected to the center of each of the four sides of the sleeve. A base is fixedly connected to the bottom of the inner frame, and limit holes are opened at each of the four corners of the base.

[0008] The present invention is further configured such that two parallel groove plates are fixedly connected to each of the four sides of the outer frame, and the sleeve is movably fitted onto the outside of the groove plates; two parallel stiffening plates are fixedly connected to each of the four sides of the inner frame, and the stiffening plates are movably fitted into the inside of the corresponding groove plates; the stiffening plates are fixedly connected to the top of the chassis.

[0009] The present invention is further configured such that each of the four sides of the outer frame is provided with a second groove that is parallel to each other, and the stiffening plate is slidably connected to the inside of the corresponding second groove.

[0010] The present invention is further configured such that a top plate is fixedly connected to the top of the outer frame, and a limiting post adapted to the limiting hole is fixedly connected to each of the four corners of the top of the top plate.

[0011] The present invention is further configured such that two fences are stacked one on top of the other, and the lower fence is equipped with a base plate with a honeycomb pattern at the bottom.

[0012] The present invention is further provided that handles are fixedly connected to both sides of the outer frame.

[0013] The present invention is further provided that each of the four corners of the base plate is provided with a threaded hole that matches the limiting hole, and the threaded hole is fitted with an installation bolt that passes through the limiting hole.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model, through the movable connection between the outer frame and the inner frame, the sliding fit of the fixing block in the first slot, and the multi-position fixing structure of the hand-tightened bolt and the different positioning holes on the fixing frame, can quickly adjust the height of the sand box according to the height requirements of the casting, without the need to replace sand boxes of different specifications, reducing equipment replacement time and improving casting efficiency.

[0016] 2. This utility model, through the interlocking of the groove plate on the outer frame and the stiffening plate driven by the inner frame, and the structure of the stiffening plate sliding along the second groove, can not only enhance the overall structural strength of the enclosure and improve the load-bearing capacity of the sand box, but also realize the flexible adjustment of the stiffening plate position by moving synchronously with the inner frame, so as to adapt to the structural support requirements under different working conditions.

Detailed Implementation

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1 to 4This utility model relates to a sandbox with multi-level height adjustment and rib plate position adjustment, including a enclosure 100 and an outer frame 101. An inner frame 102 is movably fitted inside the outer frame 101. Two parallel first slots 101a are formed on each of the four sides of the outer frame 101. Two fixing blocks 105 are fixedly connected to each of the four sides of the inner frame 102, which are slidably connected to the corresponding first slots 101a. Vertically downward fixing brackets 104 are fixedly connected to the center of each of the four sides of the outer frame 101, and positioning holes 104a are equidistantly formed in the vertical direction inside the fixing brackets 104. Hoops 103 are movably fitted onto the outer frame 101 and the four fixing brackets 104, and the hoops 103 are fixedly connected to the outside of the fixing blocks 105 by bolts. The four sides of the sleeve 103 are rotatably connected to hand-tightening bolts 108 that are compatible with the positioning holes 104a. The bottom of the inner frame 102 is fixedly connected to the chassis 110. The chassis 110 has limit holes 110a at each of its four corners. By the movable connection between the outer frame 101 and the inner frame 102, and the sliding of the fixing block 105 in the first slot 101a, the initial adjustment of the height of the enclosure 100 can be achieved. By using the cooperation of the hand-tightening bolts 108 with different positioning holes 104a on the fixing frame 104, multiple height fixation can be achieved. The adjustment operation is convenient and the fixation is stable. In actual casting, the height of the sand box can be quickly adjusted according to the height requirements of the casting without the need to change sand boxes of different specifications, reducing equipment change time and improving casting efficiency.

[0027] Specifically, a top plate 111 is fixedly connected to the top of the outer frame 101. Each of the four corners of the top plate 111 is fixedly connected with a limiting post 111a that matches the limiting hole 110a. When the two enclosures 100 are stacked on top of each other, the limiting post 111a on the top plate 111 can be inserted into the limiting hole 110a of the base plate 110 of the upper enclosure 100, which plays a precise positioning role, effectively improves the stability when stacked, and avoids displacement during use.

[0028] Two enclosures 100 are stacked one on top of the other, and the lower enclosure 100 is equipped with a bottom plate 200 with a honeycomb bottom. The bottom plate 200 with a honeycomb bottom reduces the overall weight of the sand box while ensuring structural strength. Handles 112 are fixedly connected to both sides of the outer frame 101. The handles 112 make it easy for operators to carry and move the sand box.

[0029] The base plate 200 has threaded holes 201 at each of its four corners that are compatible with the limiting holes 110a. The threaded holes 201 are fitted with mounting bolts 109 that pass through the limiting holes 110a. By the cooperation of the mounting bolts 109 passing through the limiting holes 110a and the threaded holes 201, a stable connection between the base plate 200 and the enclosure 100 can be achieved.

[0030] The operation process of this embodiment is as follows: When it is necessary to adjust the height of the sand box, first loosen the hand-tightening bolt 108 on the sleeve 103 so that the hand-tightening bolt 108 is disengaged from the positioning hole 104a on the fixing frame 104. At this time, the fixed relationship between the sleeve 103 and the fixing frame 104 is released, and the inner frame 102 can slide freely in the first slot 101a through the fixing block 105. The operator can hold the handle 112 to lift or press down the inner frame 102 to easily adjust the height of the enclosure 100. After adjusting to the position that meets the height requirements of the casting, screw the hand-tightening bolt 108 into the positioning hole 104a of the corresponding height to complete the height fixation, thereby meeting the height adaptation requirements of different castings.

[0031] Example 2

[0032] Please see Figure 1 and Figure 2 Based on the first specific embodiment, two parallel groove plates 106 are fixedly connected to each of the four sides of the outer frame 101, and the sleeve 103 is movably sleeved on the outside of the groove plate 106. Two parallel stiffening plates 107 are fixedly connected to each of the four sides of the inner frame, and the stiffening plates 107 are movably sleeved on the inside of the corresponding groove plate 106. The stiffening plates 107 are fixedly connected to the top of the chassis 110. The sleeved cooperation between the groove plate 106 and the stiffening plate 107 can enhance the overall structural strength of the enclosure 100 and improve the load-bearing capacity of the sand box. At the same time, the stiffening plates 107 move synchronously with the inner frame 102 to realize flexible adjustment of the stiffening plate position and adapt to the structural support requirements under different working conditions.

[0033] Specifically, the outer frame 101 has parallel second slots 101b on all four sides, and the stiffening plate 107 is slidably connected to the inside of the corresponding second slot 101b.

[0034] The operation process of this embodiment is as follows: When the inner frame 102 moves up and down during the sand box height adjustment, it will drive the stiffener 107 to move synchronously. The stiffener 107 slides along the second groove 101b and always maintains the sleeve state with the groove plate 106. When the sand box height is fixed, the composite support structure formed by the stiffener 107 and the groove plate 106 improves the load-bearing capacity of the sand box.
