The blowing process of the blow molding machine mainly has 6 steps:

1) First put the heated plastic embryo into the mold;

2) Use a clamping cylinder to tighten the mold;

3) Lock the mold with high pressure or mechanical structure;

4) Medium and high pressure pre-blowing, meanwhile, the action of stretching the cylinder makes the mold expand;

5) High pressure blowing, the preform is shaped according to the mold, and the pressure is maintained for a certain time;

6) Release the high pressure in the formed bottle and reset the cylinder-take the bottle.

Pneumatic equipment for bottle blowing molds is used in many places during the operation of the blow molding machine; from discharging—locking—stretching—high pressure air blowing / deflation—bowing, this series of actions are assisted by pneumatic equipment. . Such as stretching the high-pressure air blowing and deflation circuit, the gas path is divided into two parts, the atmospheric part and the high pressure part
