Description

Technical Field

[0001] The utility model relates to the technical field of packaging bottle production, in particular to a cooling device for packaging bottle production. Background Art

[0002] During the production process of packaging bottles, the preforms need to be heated before blow molding. After the preforms are blow molded in the mold, the plastic bottles formed in the mold need to be cooled by a cooling device to quickly harden the plastic bottles. However, the existing cooling devices are usually arranged inside the mold. After the packaging bottles are cooled, the coolant is still inside the mold, which can easily cause the inner cavity temperature of the mold to be too low. During the blow molding process of the preforms, the outer wall of the preforms is affected by the coolant and quickly cooled and shaped, which can easily cause uneven wall thickness of the molded bottle and poor blow molding effect of the outer wall of the preforms.
