Plastic bottle cap injection molding mold

The invention discloses a plastic bottle cap injection molding mold, and relates to the technical field of injection molding equipment. The plastic bottle cap injection molding mold comprises a nozzle cleaning device. According to the plastic bottle cap injection molding mold, through the translation cleaning mechanism, the diameter of the cleaning thread body and the diameter of the bottom of the cleaning thread head are the same as the diameter of the inner wall of the nozzle, it can be guaranteed that the cleaning thread body and the cleaning thread head are tightly attached to the inner wall of the nozzle, and the cleaning thread head is conical, so that advancing resistance can be reduced; when waste blocked on the inner wall of the nozzle is close, the thread cambered surface of the cleaning thread head gradually contacts with the waste and extrudes the waste, equivalently, the contact area of the waste and the cleaning thread head is increased, the high-temperature electric heating rod heats the cleani
