This invention discloses a plastic bottle blow molding system and method, relating to the field of plastic packaging molding technology. The system includes a zoned precision preheating mechanism, a multi-stage air-blowing stretch blow molding mechanism, an internal and external composite cooling mechanism, and a PLC control mechanism, arranged sequentially along the preform processing direction. The method includes preform conveying, zoned precision preheating, multi-stage air-blowing stretch blow molding, internal and external composite cooling, and demolding. This invention improves the preform temperature control accuracy to within ±1℃ and reduces wall thickness deviation to within ±0.05mm through independent cooling at the bottle mouth, 5-segment axial zone heating, and PID closed-loop temperature control. The precise synchronous coordination of three independent air paths with the stretch rod movement solves molding defects such as wrinkles and pitting. Synchronous cooling through a double-spiral reverse cooling channel outside the mold and a through-type cooling channel inside the stretch rod shortens the molding cycle from 3-4 seconds to 2-2.5 seconds.

This invention relates to a device and method for testing the airtightness of airbags in air-shield dams, belonging to the field of airtightness testing technology. It includes a main body, an airbag disposed between clamping plates, an injection pipe on one side of the main body, an air outlet on one side of the airbag, a locking assembly between the injection pipe and the air outlet, a stirring assembly inside the injection pipe, and a clamping assembly on one side of the lead screw. This invention achieves automatic opening of the air passage during docking and bidirectional automatic sealing during separation through plug-in self-sealing, preventing gas leakage and blocking impurities such as water vapor and dust from entering the air passage and the airbag interior. Combined with a mechanical locking structure using inclined plane transmission, it can resist the impact of inflation pressure and the tensile force generated by airbag deformation, ensuring that the interface remains secure and does not detach throughout the process. This eliminates external leakage not caused by the airbag itself, ensuring that the test results accurately reflect the airbag's sealing state and significantly reducing the probability of misjudgment.
