AI Technical Summary
In existing vertical disc injection molding machines, the connection between the pipeline and the disc during gas transport causes rotational obstruction and entanglement problems.
The design employs a hollow flow channel and air passage interface. The air passage interface is connected to the disc by a piston rod, which avoids the interference of traditional pipeline connections on the rotation of the disc and achieves smooth airflow transmission.
This effectively avoids pipe entanglement, ensures the rotational freedom of the disk, and reduces the number of pipes at the center of the disk.
