A first limit hole 22 corresponding to the ball block 4 is provided inside the first limit groove 21. A spring 6 is installed at the bottom end of the sleeve 5, and a connecting cylinder 7 is installed on the outer wall of the sleeve 5. A support plate 71 is installed at the end of the connecting cylinder 7, which can lock the mold well and can also release the lock well;
[0034] A protruding block 8 is installed at the end of the sliding plate 9, and a second limit groove 81 and a second limit hole 82 corresponding to the ball block 4 are provided at the end of the protruding block 8, which can better combine with the fixed plate 1, so as to lock the mold.
[0035] Please refer to Figure 2 and Figure 3 , multiple groups of fixed blocks 2 are symmetrically installed at the end of the fixed plate 1, and the depth inside the fixed block 2 corresponds to the length of the protruding block 8, which can evenly lock the sliding plate 9 and does not affect the normal use of the mold.
[0036] Please refer to Figure 2 , two groups of protruding blocks 8 are symmetrically installed at the end of the sliding plate 9, which can better combine with the fixed plate 1. A second limit groove 81 and a second limit hole 82 are provided at the end of each group of protruding blocks 8, and the outer diameter of the protruding block 8 corresponds to the inner diameter of the end of the fixed block 2, making the locking effect of the mold better and improving the production efficiency of the mold.
[0037] Please refer to Figure 5 , the spring 6 is fixedly connected between the fixed block 2 and the sleeve 5, and the diameter of the spring 6 is larger than the inner diameter of the sleeve 5, which can more conveniently release the lock of the mold and does not affect the next use of the mold.
[0038] Please refer to Figure 4 - Figure 6 , the rubber ring 3 is movably installed at the end of the first limit groove 21, and the outer diameter of the rubber ring 3 is larger than the inner diameter of the sleeve 5, which can limit the sleeve 5 and make the working efficiency of the mold higher.
[0039] Please refer to Figure 5 and Figure 6 , the inside of the connecting cylinder 7 is designed in a stepped shape, and the horizontal plane at the end of the connecting cylinder 7 on the side of the ball block 4 is the lowest, which can lock the mold better and can also release the restriction at any time.

[0041] The working principle of the present utility model is as follows: When using the mold, when the protruding block 8 installed at the end of the sliding plate 9 is combined with the fixed block 2, the support plate 71 is pushed downward during the combination process until the protruding block 8 is completely combined with the fixed block 2. At this time, the ball block 4 will be stuck into the second limiting hole 82, and the sleeve 5 will generate a squeezing force on the ball block 4, so that the mold reaches the locked state. When the mold is used up, the sliding plate 9 needs to be picked up. During the picking process, the support plate 71 will be touched. At this time, the support plate 71 will move downward. When the support plate 71 moves, it will drive the connecting cylinder 7 to move, thus driving the sleeve 5 to move. When the sleeve 5 moves, it will generate a squeezing force on the spring 6. At this time, the sliding plate 9 is moved upward. At this time, the ball block 4 is not subjected to the squeezing force of the sleeve 5. As the sliding plate 9 moves, the ball block 4 will slide out from the second limiting hole 82. At this time, the sliding plate 9 can be taken out smoothly. At this time, the support plate 71 is no longer stressed, and the sleeve 5 will return to its original position under the action of the spring 6. At this time, it will also drive the connecting cylinder 7 and the support plate 71 to return to their original positions.
