Abstract

The invention discloses a method for cooling and sizing plastic profiles and a device for realizing same. The method comprises the following steps: firstly, the plastic profiles are extruded by an extruder, and then the first cooling and sizing are carried out on a first section of dry-type shaper by vacuum forming and injecting cooling water to a cooling hole; secondly, an open-type cooling tankis added behind the first section of dry-type shaper, the cooling tank is internally filled with coolants, and the plastic profiles are dissipated of heat and cooled by the coolants; and thirdly, a second section dry-type shaper is added behind the open-type cooling tank, the plastic profiles enter the second section of dry-type shaper after being dissipated of heat and cooled in the open-type cooling tank, and then second vacuum sizing and cooling are carried out. The existing dry-type shaper of the invention is divided into two parts for using, is matched with the open-type water tank reasonably simultaneously, which changes the view that improvement of cooling and sizing effect by a big margin can be realized only in the condition that the dry-type shaper is connected with other specialcooling devices. The invention is especially suitable for processing hollow plastic profiles similar with PVC buckles and the like.

Description

technical field [0001] The invention relates to a method for processing plastic profiles and a device for realizing the method, in particular to a method for cooling and shaping continuously extruded plastic profiles and a device for realizing the method. Background technique [0002] Plastic profiles are generally raw materials that are melted and plasticized in the barrel of the extruder, and then pass through the die to obtain a certain melted blank, and then enter the shaping mold. The existing shaping mold has only one part, and the length of the shaping mold is often between 54-55CM. There are vacuum holes and cooling holes on the shaping mold. The finished product is extruded from the other end of the mold. Due to the relatively closed environment of the existing mold, the heat dissipation effect is not good, and the cooling and shaping effect is not good. Therefore, in order to improve the cooling effect, many manufacturers need to be equipped with a special cooling...
