The tension spring 11 is sleeved on the cleaning rod 6 and corresponds to the position between the clamping plate 10 and the movable plate 9. The upper end of the tension spring 11 is connected to the clamping plate 10, and the lower end is connected to the upper surface of the movable plate 9; the inclined surfaces of the left and right side plates 1 and the bottom plate 4 are respectively provided with sliding grooves 2 matching the bottom plate 4 of the cleaning rod 6; the upper end surface of the baffle 3 is provided with a handle 13.

[0021] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0022] According to the instruction manual Figure 1-3It can be known that when the utility model is cast, the baffle 3 is first inserted into the vertical limit groove 14 of the front and rear side plates 15. The baffle 3 cannot move horizontally. After assembling multiple sand molds 5, they are placed in the placement groove composed of a pair of left and right side plates 1, a pair of front and rear side plates 15 and a bottom plate 4, and buried in fine sand 7. At the same time, the driving component drives the moving plate 9 and the cleaning rod 6 on the moving plate 9 to move, so that it cooperates with the baffle 3 to clamp the multiple sand molds 5 to ensure the stability of the sand mold 5, thereby improving the casting quality. The cleaning rod 6 here can only move vertically and has good horizontal stability. After the sand mold 5 is fixed, pouring is carried out, and it cools naturally after pouring. After cooling and molding, the driving component drives the moving plate 9 and the cleaning rod 6 to move, loosen the sand mold 5, break the sand mold 5, and take out the casting.

[0023] When the next sand casting is carried out, the sand mold 5 fragments in the fine sand 7 need to be cleaned. First, the personnel manually remove the baffle plate 3 and start the driving assembly. The driving assembly drives the movable plate 9 and multiple cleaning rods 6 to move in the placement slot. The multiple cleaning rods 6 are arranged in a "wooden comb" shape, and the distance between each two cleaning rods 6 is designed according to actual needs. During the movement, the multiple cleaning rods 6 intercept and push the fragments larger than their spacing to move, and the fine sand 7 is basically unaffected. Since the cleaning rod 6 can move vertically in the limiting hole 8 relative to the movable plate 9, and the force given to the cleaning rod 6 by the elastic member is downward, when the cleaning rod 6 moves to the inclined surface of the left and right side plates 1, it is squeezed and moved upward to ensure that the cleaning rod 6 can continue to push the sand mold 5 fragments in the horizontal direction until it is pushed to the outside of the placement slot to complete the cleaning of the sand mold 5 fragments. Compared with the prior art, the utility model drives the movable plate 9 and a row of cleaning rods 6 on the movable plate 9 which can be extended and retracted in the vertical direction by a driving assembly, thereby scraping the sand mold 5 fragments mixed with fine sand 7 in the placement groove out of the placement groove, realizing automatic cleaning, and improving the cleaning efficiency and cleaning effect.

[0024] Among them, the driving assembly includes a motor 18, a threaded rod 17, a fixed plate 16 and a connecting plate 21, the connecting plate 21 is fixedly connected to one end of the movable plate 9, one end of the threaded rod 17 is connected to the output end of the motor 18 on the front and rear side plates 15, and the other end is rotatably connected to the side wall of the fixed plate 16 on the front and rear side plates 15. During operation, the output end of the motor 18 rotates to drive the threaded rod 17 to rotate, and the threaded rod 17 is screwed into the threaded hole 20 of the connecting plate 21. Therefore, the rotation of the threaded rod 17 can drive the connecting plate 21 to move, thereby driving the movable plate 9 to move horizontally. The driving assembly here can also be designed into two groups, corresponding to the two ends of the movable plate 9, respectively, to further ensure the stability of the movable plate 9 when moving. In addition, a second limiter 19 can also be set between the connecting plate 21 and the side walls of the front and rear side plates 15 to ensure the stability of the horizontal sliding connection between the two. In particular, a heat insulation pad 22 is set between the motor 18 and the front and rear side plates 15 to prevent the motor 18 from being affected by high temperature.

[0025] Among them, the elastic member adopts a tension spring 11, and a clamping plate 10 is arranged on the top of each cleaning rod 6. The tension spring 11 is sleeved on the cleaning rod 6 and corresponds to the position between the clamping plate 10 and the movable plate 9. The upper end of the tension spring 11 is connected to the clamping plate 10, and the lower end is connected to the upper surface of the movable plate 9. When working, the tension spring 11 always gives a downward force to the clamping plate 10 and the cleaning rod 6 to ensure that the bottom of the cleaning rod 6 is in contact with the bottom plate 4 and the left and right side plates 1, thereby ensuring the cleaning effect of the sand mold 5 fragments.

[0026] Among them, the inclined surfaces of the left and right side panels 1 and the bottom plate 4 are respectively provided with sliding grooves 2 that match the bottom plate 4 of the cleaning rod 6 to ensure the stable movement of the cleaning rod 6. Of course, the lower end of the cleaning rod 6 can also be designed into a hemispherical shape to ensure smoother sliding on the left and right side panels 1.

[0027] In addition, a handle 13 is provided on the upper end surface of the baffle 3 to facilitate personnel to disassemble and install the baffle 3.
