[0002] The core mold vibration pipe-making process uses a circularly moving distribution device to pour the concrete mixture between the inner and outer tube molds. A high-frequency vibrator installed in the inner mold transmits the excitation force through a tensioning connecting ring, which is then transferred from the inner mold to the concrete mixture in the tube mold. Due to the strong high-frequency vibration force, the concrete mixture liquefies and fills the mold, while simultaneously displacing air and gradually forming a dense shape.
