An internal thread double-port barrel bottom blow pin structure belongs to hollow blow molding technology, including a unscrewing blow pin rod assembly, a blow pin lifting assembly, a blow pin expanding assembly, a height adjusting assembly and a limiting assembly. The lifting assembly is connected with the height adjusting assembly, the expanding assembly is mounted on the lifting unit, the unscrewing rod assembly is fixed on the expanding assembly, and the limiting assembly is installed at one end of the expanding assembly. The blow pin integrates multiple functions with strong versatility. The specially designed cooling and sealing structure adopts direct water channel circulation to the nozzle inner cavity for efficient cooling, and the rotary sealing structure achieves zero water leakage. Equipped with an integrated cutting blade, it realizes automatic flash trimming.
