Device for the manufacture of containers comprising a mould and a fluidic coupling plug fitted with means for clamping against the mould

Device (10) for producing containers by blow molding, the device (10) comprising:

• a mold (12) that comprises a wall defining a molding cavity with a vertical axis (A), the mold (12) being equipped with at least one piping for the circulation of a heat-exchanging fluid, the at least one piping having an inlet opening (30) for the heat-exchanging fluid and an outlet opening (32) for the heat-exchanging fluid on an external surface (34) of the mold (12);
• a mold carrier (20, 22) in which the mold (12) is mounted in a detachable manner;
• a plug (38) that is equipped with a supply pipe (40) for the supplying heat-exchanging fluid and a discharge pipe (42) for discharging the heat-exchanging fluid, with the plug (38) being mounted to slide longitudinally on the mold carrier (20, 22) between a front connection position in which the plug (38) is interlocked with the inlet and outlet openings (30, 32) of the mold (12) and in which the supply pipe (40) and the discharge pipe (42) are connected simultaneously with the inlet opening (30) and the outlet opening (32), respectively, and a rear disconnection position in which the plug (38) is released from the inlet and outlet openings (30, 32);
• and
• means for tightening the plug (38) against the mold (12) in a connection position,
• wherein the plug (38) comprises a sliding control stop (84) that is carried in a stationary manner by the plug (38).

• and
• means for tightening the plug (38) against the mold (12) in a connection position, wherein the tightening means comprise,
• a catch (60) that is carried in a stationary manner by the mold (12) in front of the plug (38) when the mold (12) is mounted on the mold carrier (20, 22), and
• a tightening pin (64) that is carried in a mobile manner on the plug (38) between a tightening position in which the pin (64) is hooked behind the catch (60) in such a way as to tighten the plug (38) longitudinally against the mold (12), and a release position in which the pin (64) is offset relative to the catch (60) to make it possible for the plug (38) to slide toward its rear disconnection position, and
• wherein the tightening pin (64) is controlled in its tightening position by a cam mechanism.
