This invention discloses a plastic pipe extrusion die, belonging to the technical field of extrusion die equipment. This solution introduces cooling airflow through exhaust blocks at both ends of the upper arc-shaped adsorption plate inside the upper compensation hood. This airflow spreads between the arc surface and the upper half of the pipe to form a surface-fitting low-temperature air film, which is then drawn back by the upper connecting block in the middle of the arc surface. Combined with the lower cavity airflow's design of supporting without actively cooling to maintain plasticity, this constitutes a controlled artificial temperature difference replacing a random temperature difference. This allows the upper half of the pipe to obtain anti-collapse stiffness while avoiding the lower half from rapidly cooling and locking in sagging stress.
