[0027] By arranging two correction plates 1 to clamp the sand mold 2 and adjust the falling track of the sand mold 2, the detection assembly 5 is arranged to judge whether the correction plate 1 is adjusted in place, if not, the remote control module can control the power assembly 4 to adjust the rotation angle of the correction plate 1 until the detection assembly 5 sends a signal that the adjustment is in place, that is, the correction of the falling track of the sand mold 2 is completed, thereby avoiding artificial crouching to visually confirm the falling point of the sand mold 2 from a narrow space, ensuring that the center of the sand mold 2 is aligned with the center through hole of the partition plate 3, avoiding time-consuming and laborious alignment process and easily existing errors, and improving work efficiency.
[0028] As shown in the application, Figure 3 The detection assembly 5 comprises a moving column 502, one end of the moving column 502 is provided with a moving plate 503, the other end is provided with a contact plate 505, and the inner end of the containing space is provided with a pressure sensor 506 corresponding to the contact plate 505; the detection assembly 5 also comprises a fixed plate 501, the fixed plate 501 is arranged at the opening end of the containing space, a plurality of through holes are uniformly arranged on the fixed plate 501, and the moving column 502 is arranged in the through holes; the outer side of the moving column 502 is provided with a spring 504, one end of the spring 504 is fixedly arranged on the contact plate 505, and the other end is arranged on the side of the fixed plate 501.
[0029] In use, when the correction plate 1 rotates with the polygonal column 6 as the center, the moving plates 503 on the two correction plates 1 abut against each other. When the moving plate 503 on any correction plate 1 abuts against the other correction plate 1, the moving plate 503 drives the moving column 502 to move along the through hole, thereby driving the contact plate 505 to press on the pressure sensor 506.

A motor 404 is fixedly arranged on the connecting plate 405, and a driving gear 403 is fixedly connected to the output shaft of the motor 404 and engaged with the gear ring 402.

[0034] The working principle of the utility model is as follows: first, the correction plate 1 is placed, and the staff moves the device by gripping the curved column and the straight column, and the connecting plate 405 and the rotating drum 401 are sleeved on the polygonal column 6, and the correction plate 1 is placed on both sides of the partition plate 3.
[0035] Secondly, the falling trajectory of the sand mold 2 is preliminarily adjusted, the remote control module controls the motor 404 to rotate forward, thereby driving the driving gear 403 to rotate, the driving gear 403 drives the rotating drum 401 to rotate through the gear ring 402, the rotating drum 401 drives the correction plate 1 to rotate around the polygonal column 6 as the center, towards the center through hole of the partition plate 3, so that the semicircular parts of the two correction plates 1 are close to each other, and the sand mold 2 is clamped.
[0036] Then, the correction plate 1 is adjusted to be in place, when the moving plate 503 on any correction plate 1 abuts against the other correction plate 1, the moving plate 503 drives the moving column 502 to move along the through hole, thereby driving the contact plate 505 to press on the pressure sensor 506, when all the contact plates 505 are pressed on the pressure sensor 506, it represents that the side surfaces of the semicircular parts of the two correction plates 1 have abutted against each other at this time, the centers of the two semicircular parts have coaxial lines with the center through hole of the partition plate 3, and the center of the sand mold 2 has been aligned to the center through hole of the partition plate 3, the remote control module receives the signal that the pressure sensor 506 has been pressed, that is, the signal that the adjustment is in place, and stops the rotation of the motor 404.
