At this time, remove the cleaning box from the feed barrel to clean the impurities in the cleaning box. The entire process does not require suspending the feeding of molten aluminum, thereby improving production efficiency.

[0023] 2. When it is necessary to limit the rotation of the fixed plate, the two fixing rods are inserted into the locking grooves, and then the fixing rods are inserted into the locking holes on the extension rods to limit the rotation of the fixed plate; to unlock the fixed plate, just remove the positioning rod, move the fixing rod out of the locking groove, and then insert the fixing rod back into the locking hole, so that the fixing rod contacts one end of the extension rod, limiting the extension rod from moving into the sliding groove. People can drive the fixed plate to rotate relative to the locking block by holding the limit bar.

[0024] 3. When releasing the lock of the fixed plate, the limit spring can quickly push the extension rod, so that the extension rod drives the locking rod to quickly disengage from the locking groove, thereby achieving quick unlocking, saving time and effort; in addition, when the extension rod moves into the sliding groove, the limit spring is squeezed, thereby giving the extension rod a tightening force.

The filter plate 41 can filter the aluminum liquid, reduce the impurities in the aluminum liquid, and ensure product quality. When a large amount of impurities accumulate on the filter plate 41, it is only necessary to rotate the filter plate 41 90 degrees, and the impurities on the filter plate 41 will fall into the cleaning box 6 below. The filter holes on the cleaning box 6 filter the aluminum liquid, and then the filter plate 41 is rotated back to a horizontal state so that the filter plate 41 continues to filter the aluminum liquid. At this time, the cleaning box 6 is removed from the feed barrel 2 to clean the impurities in the cleaning box 6. The entire process does not require suspending the feeding of aluminum liquid, thereby improving production efficiency.

When the filter plate 41 is rotated, the filter plate 41 contacts the positioning bar 23, and the positioning bar 23 engages in the positioning groove 411, thereby restricting the filter plate 41 from further rotation, thereby allowing the filter plate 41 to quickly rotate to a horizontal state.

[0040] Reference Figure 2 、 Figure 3 and Figure 4A limit spring 76 is fixedly connected between the extension rod 73 and the bottom wall of the sliding groove 721.
