Traditional clamp locking is mostly done manually using O-type or C-type clamps to secure the upper and lower sand molds, relying on manual twisting and tightening. This is not only costly in terms of labor, but more importantly, it can lead to insufficient or uneven locking force, causing molten iron to leak from the parting surface during pouring.

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0029] Example:

[0030] This embodiment describes an automatic locking structure for a sand box with a sand-coated iron mold.

[0031] like Figure 1 As shown, Figure 1 This is a three-dimensional structural diagram of an automatic locking structure for a sand box used for coating sand on iron molds, according to this utility model. The automatic locking structure for a sand box used for coating sand on iron molds includes: a sand box, a support 11, a box clip 2, and a driving device.

[0032] The sand box is located on the support 11;

[0033] One end of the box clip 2 is attached to the flange 3 on the outside of the sand box, and the other end is connected to the drive device;

[0034] The drive unit is connected to the hydraulic station 1.

[0035] Furthermore, in combination Figure 2 As shown, Figure 2 This is a front view of the automatic locking structure of the sand box for the iron mold sand coating line shown. The sand box includes an upper sand box 9 and a lower sand box 10. The flange 1 3 is located on both sides of the upper sand box 9, and flange 2 5 is provided on both sides of the lower sand box 10.

[0036] Furthermore, a roller conveyor 4 is provided at the upper end of the support 11. The sand box is placed on the roller conveyor 4 through the flange 2 5, and under the action of the roller conveyor, the sand box moves with the roller conveyor to the casting and box assembly station.

[0037] like Figure 3 , 4 As shown, Figure 3 This is another angled schematic diagram of the automatic locking structure of the sand box for the iron mold with sand coating. Figure 4 This is a side perspective view of the automatic locking structure of the iron mold sand-coated sand box. The driving device includes a connecting plate 7 and a lifting plate 12;

[0038] The connecting plate 7 is located below the lifting plate 12;

[0039] A lifting cylinder 14 is installed below the connecting plate 7, and the lifting rod 13 in the lifting cylinder 14 passes through the connecting plate 7 and is fastened to the lower part of the lifting plate 12 by bolts;

[0040] The lifting cylinder 14 is connected to the hydraulic station 1 via an oil pipe 8.

[0041] Furthermore, a guide post 6 is provided below the lifting plate 12 by means of bolt connection, and the other end of the guide post 6 extends through to the bottom of the connecting plate 7;

[0042] Correspondingly, a bushing 16 is provided at the through point of the connecting plate 7, and the guide post 6 moves up and down along the bushing 16.

[0043] In this embodiment, four guide posts 6 are provided, respectively located at the four corners of the lifting plate. When the lifting rod drives the lifting plate to move, the guide posts evenly distribute the force released by the lifting rod, thereby improving the uniformity and stability of the clamping force when the box is closed.

[0044] Furthermore, in combination Figure 5 As shown, Figure 5 This is a side view of the automatic locking structure of the sand box for the iron mold sand coating line shown. A connecting rod 15 is provided on the lifting plate 12, and the connecting rod 15 is connected to the box clamp 2. In this embodiment, four connecting rods 15 are provided on the lifting plate 12 to evenly distribute the force from the lifting plate, ensuring uniform force distribution when the box clamp secures the sand box.

[0045] Furthermore, the oil pipe 8 includes an oil inlet pipe and an oil outlet pipe.

[0046] After the hydraulic station 1 is started, hydraulic oil enters the lifting cylinder 14 through the oil inlet pipe. The lifting rod 13 is pushed upward by the hydraulic oil pressure. The movement of the lifting rod 13 drives the lifting plate 12 to be pushed upward as well. At the same time, the connecting rod 15 on the lifting plate 12 moves the box clamp 2 upward. At this time, the box clamp 2 is in a loose state, separated from the upper sand box 9 and the upper flange 3. Conversely, oil is released to the hydraulic station 1 through the oil outlet pipe. The lifting rod 13 descends. At the same time, the lifting plate 12 descends and drives the connecting rod 15 downward. The connecting rod 15 moves the box clamp 2 downward. The upper sand box 9 is pressed tightly against the lower sand box 10 under downward pressure, realizing the tight pressing of the upper and lower sand boxes.

[0047] This invention, by setting up a drive device in conjunction with a hydraulic station and a box clamp, can achieve automatic and rapid clamping and loosening during the pouring process, reducing the labor intensity of workers; through the connecting plate, lifting plate, guide column, and connecting rod, it achieves uniform force when closing the upper / lower sand box; and with the cooperation of the hydraulic station and drive device, while the force is uniform, the parting surface between the boxes also achieves a tight connection, solving the problem of molten iron leaking from the parting surface of the upper / lower sand box during the pouring process.

[0048] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
