Molecular orientation connecting piece forming equipment and forming method

The invention discloses molecular orientation connecting piece forming equipment. The molecular orientation connecting piece forming equipment comprises a hollow mandrel, an upper forming die and a lower forming die. The two hollow mandrels are installed on the two sides of the lower forming die respectively. And an air expansion sleeve and a porous metal core are mounted on the hollow mandrel. Pipe positioning upper ring grooves are formed in the two ends of the upper forming die, and a socket forming upper cavity is formed in the middle. The middle of the lower forming die is provided with a socket forming lower cavity, the two ends of the lower forming die are provided with pipe positioning lower ring grooves, and exhaust holes are formed in the lower forming die. The connecting piece is formed by pressurizing the interior of the mold through the hollow core shaft. Meanwhile, the invention discloses a molecular orientation connecting piece forming method.
