Description

Technical Field

[0001] The utility model relates to the technical field of plastic pipe production, in particular to a sizing sleeve for a plastic pipe die. Background Art

[0002] After the pipe is extruded from the die, its temperature is still relatively high. Due to the influence of its own weight and the die-swell effect, deformation will occur. At this time, the sizing sleeve cools and shapes the pipe quickly through its internal cooling system (such as a vacuum tank, cooling water, etc.).

[0003] For example, Chinese Patent CN215040145U discloses a sizing sleeve for a plastic pipe die, which includes a sizing sleeve, a flange, a water distribution ring and a gland; the sizing sleeve is a sleeve-shaped part, with a circular hole in the middle for the pipe to pass through, and several long holes are processed on the outer wall in a staggered array. The long holes conduct the inner hole of the sizing sleeve to the outside; a circular hole is opened in the middle of the water distribution ring for the pipe to pass through, water inlet holes are processed on the outer circumference of the water distribution ring, water guiding holes are processed on the left end face of the water distribution ring, and the end of the water guiding hole is connected to the water inlet hole. There are two water inlet holes and water guiding holes in a pair, and a total of four pairs are set, which are evenly distributed along the circumferential direction of the water distribution ring. A water retaining plate protrudes to the left on the left end face of the water distribution ring. There are four water retaining plates in total, which are evenly distributed in a staggered manner along the circumference and the water guiding holes. External threads are processed on the water distribution ring.

[0004] In the above patent, although the problem of unsatisfactory cooling effect of the pipe is solved through the water distribution ring and the annular water storage tank, there is no auxiliary structure for heat dissipation on the outside of the sizing sleeve. When the sizing sleeve dissipates heat by itself, heat dissipation is only achieved through the heat exchange between its outer ring surface and the air, and the heat dissipation time is relatively long, reducing the heat dissipation effect on the surface of the sizing sleeve.
