The liquid level sensor 4 is selected from a plurality of sensors, such as a floating ball type sensor, a capacitance type sensor, a photoelectric sensor, an ultrasonic sensor and the like, the photoelectric sensor, specifically an infrared sensor, is selected for use in the embodiment, the detection mode is low in cost, and the installation and the debugging are simple. The clamping and closing assembly comprises a fixed block a1 and a movable block a2, wherein the movable block a2 is fixedly connected with the clamping actuator 6 and is driven by the clamping actuator 6 to be close to or far away from the fixed block a1, and the fixed block a1 and the movable block a2 are used for clamping the material conveying pipe 3 between the fixed block a1 and the movable block a 2. Correspondingly, the preferred clamping actuator 6 is an air cylinder, so that the cost is low, the installation and debugging are simple, and the thrust is sufficient.

The fixed block a1 is directly and fixedly arranged on the outer wall of the casting machine in a conventional mode, and a carrier such as a bracket can be additionally arranged, so that the fixed block a1 is fixedly arranged on the carrier; the movable piece a2 is directly connected to the clamping actuator 6, i.e. the output shaft end of the cylinder. Furthermore, a concave part is arranged on the side surface of the fixed block a1, which faces the movable block a2, and a convex part is arranged on the side surface of the movable block a2, which faces the fixed block a1, and the concave part and the convex part are matched to clamp the feed delivery pipe 3 for flow blocking. The recesses and projections are rounded to remove as much as possible the sharp portions of the surface to prevent damage to the feed delivery conduit 3 during clamping. Therefore, it is better to make the surfaces of the concave and convex parts into spherical surfaces. Still further, magnet a3 that can attract each other is respectively arranged on the concave part and the convex part, and magnet a3 is selectively arranged in the concave part and the convex part, so as to ensure the attaching degree of the surfaces of the concave part and the convex part, and simultaneously increase the clamping force, and in addition, the concave part and the convex part can be more effectively aligned and attached when being matched and clamped. Naturally, the positions of the concave portion and the convex portion may be changed, but the arrangement is preferable.
