A plurality of air holes 211 are disposed at the lower end of the first air pipe 21 and the upper end of the second air pipe 22.

[0034] The cleaning mechanism 30 includes a brush 31 disposed at the bottom of the inner side of the material chute 11 and a collection box 32 located on both sides of the chassis 10 along the x-direction. The brush 31 can move along the x-direction and sweep the fallen sand in the material chute 11 into the collection box 32 for collection;

[0035] The driving mechanism 40 is fixed to the placement frame 12 and is used to drive the first air pipe 21, the second air pipe 22 and the brush 31 to move along the x direction.

[0036] The automatic sand blowing device of this embodiment places the sand cores on the carrier 13 by a robot or manually, a first air pipe 21 is provided above the carrier 13, and a second air pipe 22 is provided below the carrier 13. The lower end of the first air pipe 21 and the upper end of the second air pipe 22 are both provided with a plurality of air holes 211. One end of the first air pipe 21 and the second air pipe 22 are connected with an air supply device through a conduit, and high-pressure gas is provided to the first air pipe 21 and the second air pipe 22 through the air supply device. The high-pressure gas is blown downward through the air holes 211 at the lower end of the first air pipe 21 to blow off the sand adhered to the upper surface of the sand core, and the high-pressure gas is blown upward through the air holes 211 at the upper end of the second air pipe 22 to blow off the sand adhered to the lower surface of the sand core. A driving mechanism 40 is also provided, and the first air pipe 21 and the second air pipe 22 are driven by the driving mechanism 40 to move along the x direction to realize automatic sand blowing without manual operation, thereby improving production efficiency.

[0037] This embodiment also provides a cleaning mechanism 30, and a material drop chute 11 is provided at the upper end of the chassis 10. The brush 31 is driven by the driving mechanism 40 to move along the x direction, and the fallen sand in the material drop chute 11 is cleaned and collected in the collection box 32, without the need for manual cleaning of the fallen sand by staff.

[0038] Please refer to Figure 1 , Figure 4 and Figure 6The driving mechanism 40 of this embodiment includes a screw module 41, a sliding plate 42 connected to the output end of the screw module 41, and a vertical plate 43 fixed on the sliding plate 42.

The sliding plate 42 is driven by the screw module 41, and the sliding plate 42 drives the second air pipe 22 to move along the x direction. The vertical plate 43 is fixed on the sliding plate 42, and one end of the first air pipe 21 is fixed to the vertical plate 43. Therefore, the first air pipe 21 is driven to move along the x direction at the same time, thereby achieving the effect of blowing up and down, so that the sand adhered to the upper and lower surfaces of the sand core can be blown off.

[0039] Furthermore, in order to improve the stability of the sliding plate 42 moving along the x-direction, please refer to Figure 6 In this embodiment, a guide rail 14 is further provided on the placement rack 12 , and a slide groove 421 that slidably cooperates with the guide rail 14 is provided at the upper end of the sliding plate 42 .

[0040] In addition, please refer to Figure 1 and Figure 6 The placement frame 12 is provided with a guide rod 15, and the sliding plate 42 is fixed with a sleeve 16 that matches the guide rod 15, which further improves the stability of the sliding plate 42 moving along the x-direction.

[0041] Since different types of sand cores have different heights, in order to adapt to the sand cleaning of different types of sand cores, please refer to Figure 6 A lifting adjustment mechanism 50 is provided between the sliding plate 42 and the vertical plate 43. The lifting adjustment mechanism 50 includes a mounting hole 51 provided with the vertical plate 43 along the z direction, a bolt fixed to one end of the sliding plate 42 and passing through the mounting hole 51, and a nut 52 for locking the bolt. The mounting hole 51 adopts a waist hole extending along the z direction. The position of the bolt in the mounting hole 51 is adjusted to adjust the height of the vertical plate 43, thereby adjusting the installation height of the first air pipe 21, and then the nut 52 is used to lock it, and the adjustment difficulty is low.

[0042] Please refer to Figure 1 The placement rack 12 of this embodiment can directly place the sand core. A plurality of first positioning blocks 121 are provided on the placement rack 12. The first positioning blocks 121 surround and form a first accommodating area 122 for placing the sand core. The first positioning blocks 121 can be installed at different positions on the placement rack 12 by fasteners such as screws, so as to adjust the size of the first accommodating area 122 to adapt to the placement of sand cores of different models.

[0043] Please refer to Figure 5In this embodiment, a plurality of second positioning blocks 131 are provided on the carrier 13. The second positioning blocks 131 surround a second accommodating area 132 for placing sand cores. The second positioning blocks 131 can be installed at different positions on the carrier 13 by fasteners such as screws, so as to adjust the size of the second accommodating area 132 to accommodate different types of sand cores.

[0045] Please refer to Figure 5 Both ends of the material chute 11 along the x-direction are connected with inclined surfaces 19 for guiding the fallen sand to fall into the collection box 32. When the brush 31 moves to the edge of the material chute 11 along the x-direction, the fallen sand can fall into the collection box 32 along the inclined surface 19 for collection. Through such a setting, it can be ensured that the fallen sand will not remain in the corners of the material chute 11 and cannot fall into the collection box 32.

[0046] Please refer to Figure 1 A control panel 18 is provided on the placement rack 12, and an emergency switch is provided on the control panel 18. When a fault occurs, the emergency switch can be pressed to stop the driving mechanism 40 from driving.
