[0024] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0025] 1. In this utility model, when the L-shaped frame moves, it drives the upper and lower sand boxes to move towards the L-shaped plate. When the outer surfaces of the upper and lower sand boxes are in contact with the inner walls of the rectangular holes and rectangular grooves, the servo motor stops working. At this time, the four sides of the upper and lower sand boxes are limited and aligned by the inner walls of the rectangular holes, the inner walls of the rectangular grooves, the outer surface of the push frame, and the outer surface of the L-shaped frame. This is conducive to completing the positioning work of the upper and lower sand boxes, while reducing the involvement of workers in installing pins, plates, etc., and reducing the labor intensity of the workers.

[0034] Example 1, such as Figure 1 - Figure 4 As shown, this utility model provides a high-precision sand mold positioning mold for metal casting production, including: a table body 1, with a rectangular groove 2 provided on the outer surface of the table body 1, and further including:
[0035] Multiple support plates 3 are set on the outer surface of the table body 1, and an upper plate 4 is set at the other end of the multiple support plates 3;
[0036] A rectangular hole 401 is provided on the outer surface of the upper plate 4, and a lower sand box 9 is provided on the inner wall of the rectangular groove 2;
[0037] The upper sand box 10 is set above the lower sand box 9, and the outer surface of the upper sand box 10 is provided with an iron plate 409;
[0038] An electromagnet 408 is disposed on the outer surface of an iron plate 409, and a mounting plate 407 is disposed on the outer surface of the electromagnet 408.
[0039] In this embodiment, when in use, an external power source is connected, and the operator places the lower sand box 9 in the center of the rectangular groove 2. The iron plate 409 on the outer surface of the upper sand box 10 is then attached to the energized electromagnet 408. The electromagnet 408 attracts and fixes the upper sand box 10, which enhances the stability of the upper sand box 10. With the cooperation of the elastic element 410 and the multi-section reset rod 404, the initial positions of the fixing ring 405, the electric push rod 406, and the mounting plate 407 are positioned directly above the center of the rectangular groove 2. The multi-section reset rod 404 has a spring inside, which facilitates the retraction of the multi-section reset rod 404. At the same time, the multi-section reset rod 404 extends without external force. The initial state of the multi-section reset rod 404 is the extended state.
[0040] Example 2, as Figure 1 - Figure 4 As shown, the outer surface of the table body 1 is provided with an L-shaped plate 8, the outer surface of the mounting plate 407 is provided with an electric push rod 406, the outer surface of the electric push rod 406 is provided with a fixing ring 405, the outer surface of the upper sand box 10 mates with the inner wall of the rectangular hole 401, the outer surface of the fixing ring 405 is provided with a multi-section reset rod 404, the other end of the multi-section reset rod 404 is provided with a rotating block 403, the inner wall of the rotating block 403 is provided with a connecting post 402, the other end of the connecting post 402 is provided on the outer surface of the upper plate 4, and the outer surface of the connecting post 402 is provided with an elastic element 410. The other end of component 410 is located on the outer surface of rotating block 403. One of the support plates 3 has an electric push rod 5 on its outer surface. The output end of the electric push rod 5 is provided with a push frame 6. The outer surface of the push frame 6 is provided with a servo motor 601. The output end of the servo motor 601 is provided with a rotating shaft 602. The outer surface of the rotating shaft 602 is provided with two gears 603. The outer surface of the two gears 603 is provided with a rack 604. The outer surface of the two racks 604 is provided with an L-shaped frame 7. The outer surface of the L-shaped frame 7 is in contact with the outer surfaces of the upper sand box 10 and the lower sand box 9.
[0041] In this embodiment, during use, the operator first controls the electric push rod 5 to move the push frame 6 and the L-shaped frame 7. When the push frame 6 moves, it moves the upper sand box 10 and the lower sand box 9 towards the L-shaped plate 8 within the rectangular hole 401 and the rectangular groove 2. Once the outer surfaces of the upper sand box 10 and the lower sand box 9 are in contact with the inner walls of the rectangular hole 401 and the rectangular groove 2, the electric push rod 5 stops working. Then, the operator controls the servo motor 601 to rotate the rotating shaft 602 and the gear 603. When the gear 603 rotates, it moves the rack 604 and the L-shaped frame 7. When the L-shaped frame 7 moves, it moves the upper sand box 10 and the lower sand box 9 towards the L-shaped plate 8. Once the outer surfaces of the upper sand box 10 and the lower sand box 9 are in contact with the inner walls of the rectangular hole 401 and the rectangular groove 2, the servo motor 601 stops working. At this point, all four sides of the upper sand box 10 and the lower sand box 9 are covered by the inner walls of the rectangular hole 401, the inner walls of the rectangular groove 2, and the push rod 604. The alignment of the outer surfaces of frame 6 and L-shaped frame 7 facilitates the positioning of the upper sand box 10 and lower sand box 9, while reducing the need for workers to install pins and plates, thus alleviating their workload. After the upper sand box 10 and lower sand box 9 are aligned, the workers control the electric push rod 406 to move the mounting plate 407, electromagnet 408, iron plate 409, and upper sand box 10 towards lower sand box 9. When the upper sand box 10 moves, its outer surface contacts the outer surfaces of L-shaped plate 8, L-shaped frame 7, and push frame 6. After the upper sand box 10 and lower sand box 9 are pressed together, molten metal is poured through the gating port on the upper sand box 10. After cooling for a period of time, the electric push rod 406 separates the upper sand box 10 from the lower sand box 9. The electric push rod 5 drives the push frame 6 back to its original position, and the servo motor 601 rotates to drive the L-shaped frame 7 back to its original position. After the electromagnet 408 is de-energized, the upper sand box 10 is removed and the casting is taken out.
[0042] Working principle: In use, after connecting the external power supply, the operator places the lower sand box 9 in the center of the rectangular groove 2, and attaches the iron plate 409 on the outer surface of the upper sand box 10 to the energized electromagnet 408. The electromagnet 408 attracts and fixes the upper sand box 10, which enhances the stability of the upper sand box 10. With the cooperation of the elastic element 410 and the multi-section reset rod 404, the initial position of the fixing ring 405, the electric push rod 406, and the mounting plate 407 is easily positioned directly above the center of the rectangular groove 2. The multi-section reset rod 404 is equipped with a spring inside, which facilitates the retraction of the multi-section reset rod 404 and allows the multi-section reset without external force. The rod 404 extends, and the initial state of the multi-section reset rod 404 is the extended state. During use, the operator first controls the electric push rod 5 to move the push frame 6 and the L-shaped frame 7. When the push frame 6 moves, it moves the upper sand box 10 and the lower sand box 9 towards the L-shaped plate 8 within the rectangular hole 401 and the rectangular groove 2. When the outer surfaces of the upper sand box 10 and the lower sand box 9 are in contact with the inner walls of the rectangular hole 401 and the rectangular groove 2, the electric push rod 5 stops working. Then, the operator controls the servo motor 601 to rotate the rotating shaft 602 and the gear 603. When the gear 603 rotates, it drives the rack 604 and the L-shaped frame 7 to move... When the L-shaped frame 7 moves, it drives the upper sand box 10 and the lower sand box 9 towards the L-shaped plate 8. Once the outer surfaces of the upper sand box 10 and the lower sand box 9 are in contact with the inner walls of the rectangular hole 401 and the rectangular groove 2, the servo motor 601 stops working. At this point, all four sides of the upper sand box 10 and the lower sand box 9 are aligned and limited by the inner walls of the rectangular hole 401, the inner walls of the rectangular groove 2, the outer surface of the push frame 6, and the outer surface of the L-shaped frame 7. This facilitates the positioning of the upper sand box 10 and the lower sand box 9, while reducing the need for workers to install pins and plates, thus reducing their workload. After the upper sand box 10 and the lower sand box 9 are aligned and positioned, the workers control... When the electric push rod 406 is working, it drives the mounting plate 407, electromagnet 408, iron plate 409 and upper sand box 10 to move towards lower sand box 9. When the upper sand box 10 moves, its outer surface contacts the outer surface of L-shaped plate 8, L-shaped frame 7 and push frame 6. After the upper sand box 10 contacts and presses against the lower sand box 9, molten metal is poured through the sprue on the upper sand box 10. After cooling for a period of time, the electric push rod 406 drives the upper sand box 10 to separate from the lower sand box 9. The electric push rod 5 drives the push frame 6 to return to its original position. The servo motor 601 rotates and drives the L-shaped frame 7 to return to its original position. After the electromagnet 408 is de-energized, the upper sand box 10 is removed and the casting is taken out.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
