Molding unit for containers, equipped with fluid and pneumatic circuits coming out on an upper surface

Molding unit (1) for the forming of a container (2), this molding unit (1) comprising:

• a mold (5) provided with a lateral wall (6) defining a cavity (7) having the impression of a part of the container (2);
• a fluid circuit (60) for thermal regulation of the wall (6), which includes passages drilled in it, this fluid circuit (60) for thermal regulation extending between a supply opening (62) and an evacuation opening (63);
• an insert (12) having a front surface (13) having the impression of a local part of the container (2), movable between a retracted position and a deployed position;
• an actuator (16) integral with the insert (12) to move it from its retracted position to its deployed position and vice versa;
• a pneumatic circuit (45) for controlling the actuator (16);
• wherein:
• the fluid circuit (60) for thermal regulation of the wall (6) comes out, by the supply opening (62) and by the evacuation opening (63), on an upper surface (48) of the mold;
• the pneumatic circuit for control comprises at least one primary duct (46) drilled in the wall (6) of the mold (5) and that comes out, by an upstream end (47), on the upper surface (48) of the mold (5).
