When aluminum leakage occurs, the limiting convex ring 122 can prevent the leaked aluminum liquid from continuously leaking, so that the probability of contact between the leaked aluminum liquid and the sensing piece 4 can be reduced, and the influence range of aluminum leakage accidents is effectively limited.

Referring to fig. 6 and 8, the auxiliary member 5 has a first guide surface 52 and a second guide surface 53 at a position facing away from the relief groove 54, and the first guide surface 52 is in contact with the second guide surface 53.

When aluminum leakage occurs, if the leaked aluminum liquid enters the through hole 511, the inclined design of the through hole 511 can effectively reduce the probability that the leaked aluminum liquid enters the relief groove 54 to be in contact with the sensing piece 3 through the through hole 511.

At this time, when aluminum leakage occurs, in the process that the leaked aluminum liquid flows through the first runner 7 along the contact surface 141, the convex patterns 142 have a blocking effect on the surface of the contact surface 141, so that the speed of the leaked aluminum liquid flowing through the first runner 7 is slowed down, and more time is left for the staff to process the aluminum leakage phenomenon before the aluminum liquid leaks.

The communication structure 51 further includes a plurality of grooves 512 adapted to the ribs 142, the grooves 512 are disposed on the second guiding surface 53, the grooves 512 are annular, and the axis of the grooves 512 coincides with the axis of the auxiliary member 5.

When the splitter plate 11 moves to contact against the top of the well 12, the three ribs 142 will snap into the corresponding grooves 512; at this time, a space is formed between the ridge 142 and the wall of the groove 512 for the leaked aluminum liquid to flow through, so that the flowing track of the leaked aluminum liquid in the first flow channel 7 is more tortuous, and the speed of the leaked aluminum liquid flowing through the first flow channel 7 can be further slowed down.

The embodiment of the application provides an implementation principle of an aluminum leakage monitoring device in a casting process, which comprises the following steps:
