The application discloses a kind of based on variable wall thickness control's beer bottle lightweight pressure blow forming method, through material drop accurate supply, initial mould variable pressure pressing, bottle blank vacuum shaping, mould transfer preheating, three-stage variable pressure blow forming, partition cooling solidification, annealing stabilization, eight major steps of on-line detection, in combination with variable-diameter punch, partition temperature control, dynamic punch compensation, segmented vacuum control, realize the differentiation of beer bottle mouth, shoulder, body, bottom wall thickness Precision distribution;The weight of the 500ml specification beer bottle prepared is only 260-280g, the weight reduction is 15%-23%, the bottle body thickness ratio is less than or equal to 1.8:1, and the internal pressure strength is greater than or equal to 1.6MPa, the impact strength is greater than or equal to 1.0J, the internal stress is less than or equal to 2 levels, solve the contradiction between weight reduction and strength, at the same time reduce the defective rate to 2%-3%, save raw materials and energy consumption, adapt to the demand of beer bottle large-scale green production.

The application belongs to the technical field of glass product forming equipment, and particularly relates to a glass bottle blow molding device with an openable and closable micro-hole exhaust structure, which comprises a bottle blowing machine, the side of the bottle blowing machine is connected with a first mold, the bottle blowing machine is connected with a movable seat in an extending and retracting mode, the side of the movable seat is connected with a second mold which is used in cooperation with the first mold, and the bottle blowing machine is provided with a blow molding mechanism above the first mold and the second mold; in the application, the pressure sensor is used for real-time monitoring and closed-loop adjustment of a control system, the variable-diameter pressure control hole and the sealing plug are linearly matched, stepless adjustment of a pressure relief rate is realized, the cavity pressure is stable during the blow molding process, the pressure fluctuation is avoided to affect the forming quality, the lifting stroke, the swing angle and the swing frequency of the nozzle can be adjusted according to the shape of the mold and the curvature of the bottle, the diversified production requirements are met, and the process adaptability is improved.

Methods and systems for controlling vertical glass distribution are provided. A traversing pyrometer periodically measures a parison actual temperature after the parisons exit a blank mold. The thermal camera takes a thermal image of each glass container after the glass container exits the blow mold. A vertical glass signature extraction module extracts a vertical glass distribution signature. A parison temperature estimator determines a parison estimated temperature for each vertical glass distribution signature obtained based on the vertical glass distribution signature, a most recently measured parison actual temperature and a parison stretch time. A parison temperature summer compares the parison estimated temperature to a parison set point temperature to determine a parison temperature error. A parison temperature control controls a blank mold contact time based on the parison temperature error.
