when the third mold block 23 is located in the cavity 13, the worker rotates the second member 33, and slides the second member 33 upward, so that the third mold block 23 reenters the second mold block 22, and the cavity of the forming mold 2 returns to the original size;
when the third mold block 23 and the second mold block 22 are both located in the cavity 13, the worker simultaneously rotates the second member 33 and the first member 32, and simultaneously slides the second member 33 and the first member 32 upwards, so that the second mold block 22 and the third mold block 23 reenter the first mold block 21, and the cavity of the forming mold 2 returns to the original size;
