Outlet fitting

A mold for forming a container within which an insert is embedded, and for supporting the formed container during a cooling operation subsequent to formation, the mold comprising:

• a mold body presenting a circumferential wall, and defining a hole extending through the wall between the interior and exterior of the body;
• and
• an insert support assembly for supporting the insert within the mold during formation of the container, the insert support assembly including
• a cylindrical support having a flat end wall and a threaded outer circumferential surface adapted to support the insert,
• a heat sink having an end surface in contact with the end wall of the support and a side wall protruding from the end surface away from the support,
• a clamping means for clamping the support assembly within the hole with the end surface of the heat sink flush with the mold body so that only the support and insert extend into the interior of the body, and
• a linking means between the support and heat sink for linking the support and heat sink together, the linking means being constructed of a strength capable of withstanding a shear force of a value greater than the value of the force exerted on the assembly during formation of the container and less than the value of the force exerted on the assembly by the weight of the container during the cooling operation such that the support, insert and container are able to shear free from the heat sink and mold body during the cooling operation.
