Description

Technical Field

[0001] This utility model relates to the field of casting equipment technology, and in particular to a detachable modular casting sand box. Background Technology

[0002] Foundry sand boxes are crucial tooling used in the casting process to hold molding sand and form the mold. Traditionally, multiple sand boxes are stacked to create mold cavities of varying heights. However, existing sand boxes generally suffer from certain technical shortcomings when stacking them.

[0003] During the sand box stacking process, operators often need to spend a lot of time on manual calibration, which is not only inefficient but also makes it difficult to guarantee alignment accuracy, easily leading to mold misalignment and affecting the quality of castings. In addition, the handles and other auxiliary structures used for handling existing sand boxes, if they protrude from the box surface during stacking, will directly affect the stable placement of the upper sand boxes, resulting in uneven connection surfaces and even causing the sand boxes to be loosely connected, further increasing the risk of mold deformation or collapse. Currently, the connection between sand boxes mostly uses traditional fasteners such as bolts and pins. Although the connection is strong, the disassembly and installation process is often complicated and cumbersome, time-consuming and labor-intensive, reducing production efficiency and failing to meet the needs of modern casting production for rapid mold changeover and high-efficiency operation.

[0004] Therefore, this utility model proposes a detachable modular casting sand box to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems of low alignment accuracy during stacking, low efficiency of connection and disassembly, and the impact of handles and other structures on the flatness of stacking in the existing casting sand box, this utility model aims to provide a detachable and modular casting sand box with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a detachable modular casting sand box, including: a box body, a positioning mechanism, and a connecting mechanism.

[0007] The positioning mechanism includes a positioning block disposed on the upper surface of the box and a positioning groove opened on the lower surface of the box. The positioning groove is adapted to the positioning block. The connecting mechanism includes a second connecting block fixed to one side of the upper surface of the box, and a guide groove is opened on the second connecting block.

[0008] Furthermore, the connecting mechanism also includes a first connecting block fixed to one side of the lower surface of the housing, a guide groove on the first connecting block, a connecting rod rotatably connected to the first connecting block via a first fixed shaft, a rotating shaft rotatably connected inside the connecting rod, a locking block fixedly connected to the upper end of the rotating shaft, and a knob fixedly connected to the lower end of the rotating shaft.

[0009] Preferably, the positioning mechanism further includes a groove formed on the upper surface of the box, a second fixed shaft rotatably connected to the inner wall of the groove, and a handle rotatably connected to the second fixed shaft. This design allows the handle to be stored when not in use, ensuring the flatness of the box surface.

[0010] Preferably, the outer contour of the handle is adapted to the opening contour of the groove so that the handle can be fully accommodated in the groove after rotation, so that the handle is flush with the upper surface of the box after being stored, eliminating stacking obstacles.

[0011] Preferably, the second fixed shaft is located inside the groove. This arrangement further optimizes the internal space of the groove, avoids the shaft protruding, and makes the groove area flatter.

[0012] Preferably, one end of the connecting rod is rotatably connected to the first connecting block via a first fixed shaft, and the rotating shaft is rotatably located at the other end of the connecting rod, thus dividing the functional area of ​​the connecting rod. One end is responsible for pivot connection, and the other end is responsible for locking operation.

[0013] Preferably, the knob is located at the other end of the connecting rod and exposed to the outside of the connecting rod. This exposed design allows the operator to easily and intuitively perform the rotation operation, improving the convenience of locking and unlocking.

[0014] Preferably, the first fixed shaft is located adjacent to the guide groove, and both the first fixed shaft and the guide groove are located on the first connecting block. This compact layout ensures that the locking block can be accurately aligned and pass through the guide groove during the flipping process of the connecting rod.

[0015] Preferably, the first fixed shaft is located below the guide groove on the first connecting block, so that the connecting rod flips upward and the locking block passes through the guide groove, ensuring the smooth completion of the locking action.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problems of cumbersome assembly and disassembly of sand boxes in the prior art by setting a connecting mechanism composed of a first connecting block, a second connecting block, a connecting rod, a locking block and a knob, and achieves the technical effect of quick and firm locking and convenient unlocking between the boxes.

[0017] 2. This utility model solves the problem in the prior art where the handling handle protrudes from the surface of the box and affects the flatness of the stack by setting a handle that can be stored in the groove. It achieves the technical effect of ensuring that the upper surface of the box is flat and does not affect the stable placement of the upper box.

[0018] 3. This utility model solves the problems of inconvenient positioning and low alignment accuracy when stacking casting sand boxes in the prior art by setting a matching structure of positioning blocks and positioning grooves, and achieves the technical effect of fast and accurate alignment between boxes.

[0021] 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.

[0022] Please refer to Figures 1 to 4 This utility model provides a detachable modular casting sand box, which aims to solve the problems of inconvenient positioning, low alignment accuracy, and cumbersome assembly and disassembly of existing casting sand boxes when they are stacked together.

[0023] like Figure 1 As shown, the detachable modular casting sand box includes a box body 1, a positioning mechanism 3 and a connecting mechanism 2 disposed on the box body 1. The positioning mechanism 3 is used to realize the quick alignment and handling between the stacked boxes 1, and the connecting mechanism 2 is used to firmly connect the stacked boxes 1.

[0024] The positioning mechanism 3 includes a positioning block 304 disposed on the upper surface of the box 1 and a positioning groove 305 opened on the lower surface of the box 1. The shape of the positioning groove 305 is adapted to the positioning block 304. When one box 1 is stacked on top of another box 1, the positioning block 304 of the lower box 1 is inserted into the positioning groove 305 of the upper box 1 to achieve precise positioning.

[0025] The positioning mechanism 3 also includes a groove 302 formed on the upper surface of the box 1. A second fixed shaft 303 is rotatably connected to the inner wall of the groove 302. The handle 301 is rotatably connected to the second fixed shaft 303. The outer contour of the handle 301 is adapted to the opening contour of the groove 302. The second fixed shaft 303 is set inside the groove 302, so that when the handle 301 is not in use, it can rotate around the second fixed shaft 303 and be completely accommodated in the groove 302, ensuring the flatness of the upper surface of the box 1 and not affecting the stacking of the upper box 1.

[0026] The connecting mechanism 2 includes a second connecting block 202 fixed to one side of the upper surface of the housing 1, and a guide groove 204 is provided on the second connecting block 202. The connecting mechanism 2 also includes a first connecting block 201 fixed to the corresponding side of the lower surface of the housing 1, and a guide groove 204 is provided on the first connecting block 201. When the two housings 1 are stacked on top of each other, the second connecting block 202 abuts against the upper surface of the first connecting block 201, and the two guide grooves 204 are aligned vertically.

[0027] The connecting mechanism 2 also includes a connecting rod 205 rotatably connected to the first connecting block 201. The connecting rod 205 is rotatably connected via a first fixed shaft 203. The first fixed shaft 203 is disposed adjacent to the guide groove 204 formed on the first connecting block 201. Specifically, the first fixed shaft 203 is located below the guide groove 204 on the first connecting block 201, thereby allowing the connecting rod 205 to rotate upward around the first fixed shaft 203.

[0028] One end of the connecting rod 205 is rotatably connected to the first connecting block 201 via the first fixed shaft 203. A rotating shaft 208 is rotatably provided at the other end of the connecting rod 205. The rotating shaft 208 is rotatably connected to the inside of the connecting rod 205. A locking block 206 is fixedly connected to the upper end of the rotating shaft 208, and a knob 207 is fixedly connected to the lower end of the rotating shaft 208. The knob 207 is located at the other end of the connecting rod 205 and is exposed on the outside of the connecting rod 205 so that the operator can grip and rotate it.

[0029] This structural design allows the connecting rod 205 to be flipped upwards during connection, so that the locking block 206 passes through the guide groove 204 aligned on the first connecting block 201 and the second connecting block 202. Then, the knob 207 is turned, causing the rotating shaft 208 and the locking block 206 to rotate together, so that the locking block 206 engages with the upper surface of the second connecting block 202, thereby quickly locking the two housings 1 together.

[0030] Based on the above embodiments, the present invention may further include the following preferred technical solutions: In a preferred embodiment, in order to facilitate the handling of the box 1 and ensure flatness during stacking, the positioning mechanism 3 further includes a groove 302 formed on the upper surface of the box 1. A second fixed shaft 303 is rotatably connected to the inner wall of the groove 302, and a handle 301 is rotatably connected to the second fixed shaft 303. The box 1 can be easily lifted by the handle 301.

[0031] As another preferred embodiment, in order to ensure that the handle 301 does not protrude from the surface of the box 1 when stored, the outer contour of the handle 301 is adapted to the opening contour of the groove 302, so that the handle 301 can be completely accommodated in the groove 302 after rotation. In this way, when multiple boxes 1 are stacked, the bottom of the upper box 1 can fall smoothly onto the top surface of the lower box 1, and the flatness of the connection will not be affected by the protrusion of the handle 301.

[0032] In another preferred embodiment, in order to further optimize the space utilization inside the groove 302 and ensure overall flatness, the second fixing shaft 303 is disposed inside the groove 302, so that the second fixing shaft 303 does not protrude from the top plane of the groove 302 and is completely stored together with the handle 301.

[0033] As another preferred embodiment, in order to ensure smooth rotation of the connecting rod 205 and accurate passage of the locking block 206 through the guide groove 204, the first fixed shaft 203 is arranged adjacent to the guide groove 204, and both the first fixed shaft 203 and the guide groove 204 are located on the first connecting block 201. This relative positional relationship ensures that when the connecting rod 205 is flipped, the locking block 206 on it can be accurately aligned with the guide groove 204.

[0034] In another preferred embodiment, in order to enable the connecting rod 205 to flip upward for locking, the first fixed shaft 203 is located below the guide groove 204 on the first connecting block 201. This arrangement allows the connecting rod 205 to be fully lifted when it rotates upward around the first fixed shaft 203, so that the locking block 206 can pass smoothly through the guide groove 204 and extend to engage.

[0035] The working principle of this detachable, modular casting sand box is as follows: When stacking boxes 1, first place one box 1 on a stable surface or workbench, exposing the positioning block 304 and the second connecting block 202 of the connecting mechanism 2 on its upper surface. Then, pick up the other box 1. The operator can hold the handle 301 inside the groove 302 on the box 1 for handling. At this time, the handle 301 can rotate around the second fixed axis 303 and be lifted out of the groove 302 for easy gripping. In order to achieve quick and accurate alignment of the boxes 1, align the lower surface of the upper box 1 with the upper surface of the lower box 1, so that the positioning groove 305 opened on the lower part of the upper box 1 is aligned with the lower box 1. The positioning block 304 set on the top of the box 1 is aligned and placed downwards. Since the shapes of the positioning block 304 and the positioning groove 305 are compatible, they will automatically mesh, realizing quick and accurate pre-positioning between the upper and lower boxes 1, ensuring the stability of stacking. After the alignment is completed, the handle 301 can be rotated to be fully accommodated inside the groove 302. Since the outer contour of the handle 301 is compatible with the opening contour of the groove 302, and the second fixing shaft 303 is also set inside the groove 302, the handle 301 will not protrude from the top surface of the box 1, thus avoiding affecting the stable placement of the upper box 1.

[0036] After positioning, to securely connect the two boxes 1, a connecting mechanism 2 is used for locking. At this time, the second connecting block 202 on one side of the lower surface of the upper box 1 is placed against the first connecting block 201 on the corresponding side of the upper surface of the lower box 1, and the guide grooves 204 on the two connecting blocks are aligned vertically. The operator rotates the connecting rod 205 upward around the first fixed shaft 203 at one end. Since the first fixed shaft 203 is located below the guide groove 204 on the first connecting block 201, the connecting rod 205 can smoothly rotate upward, and its other end... During rotation, the locking block 206 extends to the upper surface of the second connecting block 202 through the aligned guide groove 204. At this time, the operator rotates the knob 207 exposed outside the connecting rod 205 at the other end of the connecting rod 205. The knob 207 drives the locking block 206 to rotate together through the fixedly connected rotating shaft 208. When the locking block 206 rotates, it will be horizontally locked above the guide groove 204, that is, locked on the upper surface of the second connecting block 202, thereby firmly connecting and fixing the first connecting block 201 and the second connecting block 202 to prevent the box 1 from separating.

[0037] When it is necessary to disassemble box 1, the operation is reversed. First, the operator turns knob 207 to rotate the locking block 206 to the direction aligned with guide groove 204, so that it can pass smoothly through guide groove 204. Then, the connecting rod 205 is rotated downwards to flip it back to the initial position around the first fixed axis 203. The locking block 206 is completely disengaged from guide groove 204, thereby releasing the connection between the first connecting block 201 and the second connecting block 202. Finally, box 1 is lifted by handle 301 to complete the disassembly and separation of box 1. Through the synergistic action of positioning mechanism 3 and connecting mechanism 2, this utility model effectively solves the problems of positioning accuracy and connection efficiency when casting sand boxes are stacked together, and improves the ease of use.

Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
