Embodiment Construction

[0029] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the present invention will be specifically described below in conjunction with the accompanying drawings and embodiments. The drawings in the following description are only some embodiments of the invention. For those skilled in the art, other drawings can also be obtained based on these drawings without creative effort.

[0030] Considering that in the prior art, during the production of pipes, due to the slow cooling rate of the extruded pipes, the process response time is long, the cooling effect is not ideal, and the extruded pipes cannot be pre-cooled quickly after they are released from the mold, resulting in the occurrence of pipe blanks. To solve problems such as subsidence, the present invention designs a new type of cold air device, through the air cooling device installed directly at the extrusion port, and through the air outlet installed...

Abstract

The present invention discloses an annular extrusion air-cooling apparatus and a pipe extrusion molding apparatus. The annular extrusion air-cooling apparatus comprises an annular air hood, wherein the air hood comprises an outer circumferential housing and an inner circumferential housing; an air inlet arranged on the outer circumferential housing; an air outlet arranged on the inner circumferential housing; a cavity arranged in the annular air hood and communicated to the air inlet and the air outlet; and an air stabilizing grille arranged in the cavity.

Description

technical field [0001] The invention relates to the technical field of polymer material manufacturing, and in particular to an annular extrusion air cooling device and a pipe extrusion molding device capable of realizing rapid and efficient cooling of an extruder. Background technique [0002] Due to the advantages of low density, light weight, high strength, high rigidity, excellent insulation, good colorability, and convenient molding, polymer materials have become one of the fastest growing industries in the 21st century. Polymer plastic parts with different shapes and colors are playing an increasingly important role in our production and life. It has become a trend to replace steel and wood with plastic. [0003] With the continuous improvement of polymer material processing refinement and energy saving requirements, the cooling efficiency and speed requirements are also continuously improved. At present, the commonly used cooling methods mainly include: (1) adopting t...
