Conversion die

Abstract

The invention relates to the technical field of PE pipe formation and discloses a conversion die. By the conversion die, the problems of replacement complexity, long consumed time and energy consumption of the die in the prior art are solved. The conversion die comprises a core die base, wherein the core die base is fixedly connected with an original die, a conversion core die is fixedly arrangedat one side of the core die base, a conversion mouth die sleeves the core die base and the conversion core die and is used for being fixed with the original die, and a material guidance passage is formed between the conversion core dire and the conversion mouth die. After the conversion die is arranged, a pipe blank extruded from the original die of a plastic extruding machine directly enters thematerial guidance passage and is formed again with regard to a PE pipe with a diameter converted to 160-200, and reducing conversion of the pipe blank can be effectively achieved. By the conversion die, the original die is not needed to be assembled and disassembled, the adjustment of the PE pipe is achieved by the additionally arranging the conversion die, the conversion die is convenient to disassemble and assemble, heating is not needed, the energy consumption is low, the die is not needed to be replaced, the replacement time is shortened, the workload of an operator is reduced, and the production efficiency of the PE pipe is also improved.

Description

technical field [0001] The invention relates to the technical field of PE pipe forming, more specifically, it relates to a conversion mold. Background technique [0002] PE pipe is a very common plastic pipe in life, with stable performance and wide application range. The production of PE pipe adopts extrusion molding technology. During the extrusion molding process, the raw material enters the original mold at the end of the extruder to form a tube blank. After the tube blank is extruded, it is cooled and shaped to finally form a finished product. [0003] In the usual production process, the extruder is switched according to the diameter of the pipe, so the corresponding original mold also needs to be replaced. However, the replacement of the mold is not only labor-intensive, but also takes a long time. After the replacement, the mold needs to be reheated. The consumption of energy is huge. In addition, the installation structure of the mold and the extruder is complicat...
