FIELD: chemistry.
SUBSTANCE: invention relates to device for opening and closing mould for blowing containers from thermoplastic material, for example bottles from polyethylene terephthalate (PET), on rotor plant for pneumatic moulding. Form (10, 100) for blowing containers from thermoplastic material, comprising two half-moulds (1, 2) and device for cyclic opening and closing of half-moulds (1, 2), comprising drive shaft connected with half-moulds by means of connecting rods (14, 20) and control sleeve (15). In control bushing there are multiple holes arranged so that, when selecting holes, to which connection rods are hinged, it is possible to change maximum angle of mould opening.
EFFECT: technical result is higher mould efficiency.
