FIELD: manufacture of reservoirs from polyethylene terephthalate.
SUBSTANCE: proposed mold is used for manufacture of reservoirs from polyethylene terephthalate of various capacity, from 0.33 to 2.0 l, Mold consists of upper and lower cylindrical parts divided along geometric axis of symmetry. Bottom moves inside lower part changing volume of blow, thus making it possible to change set of mold of fixed volume. Change of volume to required magnitude ΔVset is achieved through setting measuring rings under bottom having width Δh at external radius "r": Δh=ΔVset/(π·r2), where π is number equal to 3.14.
EFFECT: increased productivity; avoidance of water cooling and manual unloading of articles.
