However, some sealing bolts have the following shortcomings in use:

[0003] 1. Currently, the sealing of the mold inlet mainly involves wrapping a nut with multiple turns of sealing tape, tightening it with a wrench, and then applying sealant to the contact point. Water can only be introduced after the sealant has basically set and cured to prevent leakage. However, the sealing performance is not good. In addition, the residual sealing tape and adhesive on the bolts and screw holes must be cleaned before the mold is used again, which makes the operation more troublesome and does not improve its practicality.
