[0021] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] Reference Figures 1 to 3 The present invention provides a sand box shuttle molding machine, including a front moving unit 1, a molding unit 2, a rear moving unit 3, an upper sand box 4, and a lower sand box 5.

[0023] The preceding moving unit 1, the shaping unit 2, and the following moving unit 3 are connected in sequence to form the preceding station, the shaping station, and the following station, respectively. The preceding station is mainly used for the moving area of ​​the upper sand box 4 and the lower sand box 5 before they move to the corresponding position of the shaping unit 2. The shaping station is used for sand shooting and compaction of the upper sand box 4 and the lower sand box 5. The following station is mainly used for the moving area of ​​the upper sand box 4 and the lower sand box 5 after they leave the shaping unit 2 and before they enter the following operation area.

[0024] There are several upper sand boxes 4 and several lower sand boxes 5, and all the upper sand boxes 4 and all the lower sand boxes 5 are arranged in layers in the vertical direction. Spatially, all the upper sand boxes 4 form a moving path above, and all the lower sand boxes 5 form a moving path below.

[0025] On the corresponding movement path, both the upper sand box 4 and the lower sand box 5 are arranged in a continuous and uniform pattern. Any selected upper sand box 4 can contact the upper sand box 4 located in front of it and the one located behind it, and any selected lower sand box 5 can contact the lower sand box 5 located in front of it and the one located behind it. Under the action of external force, adjacent upper sand boxes 4 move forward with the thrust provided by the upper sand box 4 behind them, and adjacent lower sand boxes 5 also move forward with the thrust provided by the lower sand box 5 behind them, thus achieving continuous movement on the corresponding movement path.

[0026] Each upper sand box 4 and each lower sand box 5 can sequentially pass through the preceding station, the molding station, and the subsequent station. After precise adjustment of the upper sand box 4 and each lower sand box 5, a lower sand box 5 can be precisely corresponding to each upper sand box 4 below its moving path. With this setting, the corresponding upper sand box 4 and lower sand box 5 can move to the molding station simultaneously and synchronously, and can be molded independently at the molding station at the same time.

[0027] The preceding moving unit 1, the shaping unit 2, and the following moving unit 3 can form a moving path for the upper sand box 4 and the lower sand box 5 to move continuously and operate continuously, forming a shuttle operation mode, which greatly improves the working efficiency of the shaping machine.

[0028] The upper sand box 4 and the lower sand box 5 can perform individual and simultaneous molding operations by making reasonable space planning, which doubles the operation speed. At the same time, the upper sand box 4 and the lower sand box 5 can directly perform the above operations according to the placement direction required for box assembly. After entering the subsequent process, there is no need to use box flipping equipment to flip the boxes, which effectively saves time and improves work efficiency.

[0029] As an optional implementation, the preceding moving unit 1 includes a preceding upper sand box track 11 and a preceding lower sand box track 12 located below it. Both the preceding upper sand box track 11 and the preceding lower sand box track 12 are connected to the molding unit 2. The upper sand box 4 can move on the preceding upper sand box track 11, and the lower sand box 5 can move on the preceding lower sand box track 12.

[0030] The upper sand box track 11 and the lower sand box track 12 are set separately and are arranged in layers in space, so that the upper sand box 4 and the lower sand box 5 can move on independent tracks without interfering with each other, thus improving efficiency.

[0031] As an optional implementation, the subsequent moving unit 3 includes a subsequent upper sand box track 31 and a subsequent lower sand box track 32 located below it. Both the subsequent upper sand box track 31 and the subsequent lower sand box track 32 are connected to the molding unit 2. The upper sand box 4 can move on the subsequent upper sand box track 31, and the lower sand box 5 can move on the subsequent lower sand box track 32.

[0032] The upper sand box track 31 and the lower sand box track 32 are set separately and are arranged in layers in space, so that the upper sand box 4 and the lower sand box 5 can move on independent tracks without interfering with each other, thus improving efficiency.

[0033] As an optional implementation, the modeling unit 2 includes a frame 21, a main drive assembly 22, a worktable 23, a lower auxiliary sand box 24, a guide assembly 25, a track fixing seat 26, a mold 27, and an upper auxiliary sand box 28.

[0034] The frame 21 is the main structure and is fixed to the ground or an external support structure.

[0035] The main drive assembly 22 is connected to the frame 21 and driven by the worktable 23. The main drive assembly 22 can preferably be a structure such as a hydraulic cylinder, which can drive the worktable 23 to rise or fall after it is started.

[0036] The lower auxiliary sand box 24 is movably connected above the worktable 23. Specifically, the modeling unit 2 preferably includes a third auxiliary moving component 293. The third auxiliary moving component 293 is connected to the worktable 23 and driven to the lower auxiliary sand box 24. The third auxiliary moving component 293 can drive the lower auxiliary sand box 24 to move vertically. At the same time, even if the third auxiliary moving component 293 is not working, it can still drive the lower auxiliary sand box 24 to move synchronously with the worktable 23.

[0037] The guide assembly 25 is connected to the frame 21 and serves to guide the track fixing seat 26 and the upper auxiliary sand box 28.

[0038] The track fixing seat 26 is guided and connected to the guide assembly 25 and is located above the lower auxiliary sand box 24. The lower sand box 5, the mold 27 and the upper sand box 4 are placed on the track fixing seat 26 from bottom to top. The placement relationship here is not connected, which means that the lower sand box 5, the mold 27 and the upper sand box 4 can all move upward relative to the track fixing seat 26 under the action of external force, and fall back onto the track fixing seat 26 in sequence after the external force is released.

[0039] The upper auxiliary sand box 28 is located above the upper sand box 4. The upper auxiliary sand box 28 is guided and connected to the guide assembly 25 and movably connected to the frame 21. Specifically, the modeling unit 2 also includes a first auxiliary moving assembly 291. The first auxiliary moving assembly 291 is connected to the frame 21 and driven to the upper auxiliary sand box 28. The first auxiliary moving assembly 291 can drive the upper auxiliary sand box 28 to move in the vertical direction.

[0040] As an optional implementation, the modeling unit 2 also includes a second auxiliary moving component 292, which is connected to the frame 21 and driven to the track fixing seat 26. The second auxiliary moving component 292 can drive the track fixing seat 26 to move in the vertical direction.

[0041] As an optional implementation, the track fixing seat 26 includes a fixing seat body 261, an upper sand box track 262, a mold support frame 263, and a lower sand box track 264. The fixing seat body 261 is guided and connected to the guide assembly 25. The upper sand box track 262, the mold support frame 263, and the lower sand box track 264 are connected to the fixing seat body 261 from top to bottom. The upper sand box track 262 is used to support the upper sand box 4, the mold support frame 263 is used to support the mold 27, and the lower sand box track 264 is used to support the lower sand box 5.

[0042] As an optional implementation, it also includes an upper sand hopper 6 and a lower sand hopper 7, with the upper sand hopper 6 connected to the frame 21 and the lower sand hopper 7 connected to the workbench 23.

[0043] As an optional implementation, the preceding moving unit 1, the shaping unit 2 and the following moving unit 3 are all provided with supporting rollers 8. With the cooperation of the supporting rollers 8, the upper sand box 4 and the lower sand box 5 move by means of the supporting rollers 8, thereby improving the moving efficiency and reducing structural damage to the upper sand box 4 and the lower sand box 5.

[0044] The working principle of the modeling station is as follows: After the corresponding upper sand box 4 and lower sand box 5 move to the molding station, the main drive component 22 starts, driving the worktable 23 to rise. The rise of the worktable 23 drives the third auxiliary moving component 293, the lower auxiliary sand box 24 and the lower sand hopper 7 to move upward. During the upward movement, the lower sand box 5, the mold 27 and the upper sand box 4 are driven upward in sequence. At the same time, the lower sand box 5, the mold 27 and the upper sand box 4 are separated from the track fixing seat 26. Wait for the upper sand box 4 to move upward to the docking position with the upper sand hopper 6 for sand shooting. Then the main drive component 22 continues to apply pressure for compaction. During the compaction process, the third auxiliary moving component 293 starts, driving the lower auxiliary sand box 24 to move downward. The first auxiliary moving component 291 starts, driving the upper auxiliary sand box 28 to move upward, further playing a compaction role.

[0045] During the process of the lower sand box 5, mold 27, and upper sand box 4 separating from the track fixing seat 26 and moving upward, in order to avoid the lower sand box 5 colliding with the upper sand box track 262 of the track fixing seat 26 when it moves upward to the track fixing seat 26, the second auxiliary moving component 292 will be activated at the same time as the lower sand box 5, mold 27, and upper sand box 4 move upward, driving the track fixing seat 26 to move upward and lift synchronously, thereby avoiding collision.

[0046] After compaction is complete, the main drive component 22 starts, driving the worktable 23 to descend. The worktable 23 drives the third auxiliary moving component 293, the lower auxiliary sand box 24, and the lower sand hopper 7 to move downwards simultaneously. At the same time, the upper sand box 4, the mold 27, and the lower sand box 5 move downwards by gravity and fall onto the track fixing seat 26 in sequence. The third auxiliary moving component 293 starts, driving the lower auxiliary sand box 24 back to its initial position. The second auxiliary moving component 292 starts, driving the track fixing seat 26 to move downwards and back to its initial position. The first auxiliary moving component 291 starts, driving the upper auxiliary sand box 28 back to its initial position, so that the molding station is completely back in place, waiting for the next set of corresponding upper sand boxes 4 and lower sand boxes 5 to move to the molding station, and repeating the above operation.

[0047] Based on the above structural design, the molding machine can also be combined with airflow suspension sand shooting and multi-contact compaction to make the compaction effect better and more suitable for products with a large convex-concave ratio.

[0048] Furthermore, by adding the first auxiliary moving component 291, the working position of the upper auxiliary sand box 28 can be finely adjusted, thereby achieving adjustable sand box height.

[0049] Furthermore, by adding the third auxiliary moving component 293, the working position of the lower auxiliary sand box 24 can be finely adjusted, thereby achieving adjustable sand box height.

[0050] The sand box shuttle molding machine adopts the working principle of box molding, which has a higher sand utilization rate, better wrapping effect, and higher molten iron utilization rate.

[0051] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
