DEVICE FOR PRODUCTION OF PLASTIC VESSELS BY BLOW MOLDING Russian patent published in 2006 - IPC B29C49/46 B29C49/12 B29C49/78 

FIELD: device for production of plastic vessels by its blow molding in a mould, whose cavity configuration corresponds to the shape of the finished vessel retained on the side of its open end by a fastening appliance with gas supply lines.

SUBSTANCE: a movable exhaust punch passes through the mentioned fastening appliance in the axial direction, provision is also made for a device for ignition of the explosive gaseous mixture inside the vessel/ To make the plastic vessel more attractive due to its production with absolutely transparent walls and enhance the precision of its manufacture, according to the invention the fastening appliance is made for building the end facing the opposite end of the vessel in the impermeable condition for fluid (in the conjugated packing surface) with the main distribution unit through which passes the exhaust punch for motion in the axial continuation of the fastening appliance. In the first section of the main distribution unit turned from the vessel provision is made for at least one first connecting opening for supply of fluid, and in the opposite second section of this main distribution unit turned to the vessel provision is made for at least one more-second-connecting opening for supply of fluid. The ducts formed by these at least two connecting openings are in communication with each other in the main distribution unit in its second section. Only one common flow-through duct is formed between the point of connection of these ducts and the fastening appliance.

EFFECT: the plastic vessel is made more attractive due to the fact that it is made, for example, with absolutely transparent walls, enhanced precision of its manufacture.
