Single-layer plastic pipe extrusion fine adjustment die

Abstract

A single-layer plastic pipe extrusion fine adjustment die comprises an outer die body, a core die body, a deflection adjusting module, a plurality of adjusting screws and a die locking plate. The outer die body is a rotation body, and a horn-mouth-shaped containing groove is formed in the center of the outer die body, wherein the diameter of the containing groove is gradually increased from the front end to the rear end. A cylinder-shaped installing groove is formed in the front end of the outer die body, and the installing groove communicates with the containing groove. An installing disc isarranged at the rear end of the core die body, and the installing disc is installed and fixed to the rear end of the outer die body. A horn-mouth-shaped forming die body is arranged towards the frontin a protruding manner from the installing disc, and the diameter of the forming die body is gradually increased from the front end to the rear end. The forming die body is inserted in the containinggroove. A horn-mouth-shaped storage groove is formed in the deflection adjusting module and communicates with the containing groove. The forming die body is inserted in the storage groove. A forming channel is formed among the inner wall face of the containing groove of the outer die body, the inner wall face of the storage groove of the deflection adjusting module and the outer wall face of the forming die body. By means of the single-layer plastic pipe extrusion fine adjustment die, the machine adjusting time is shortened, and raw material waste is reduced.

Description

technical field [0001] The invention relates to a single-layer plastic pipe extruding fine-tuning die, which is used for extruding the single-layer plastic pipe. Background technique [0002] In the normal extrusion process of conventional single-layer plastic pipes, the concentricity of the plastic layer of the pipe must be manually adjusted; and adjusting the concentricity often takes a long time and generates more waste for adjustment, resulting in waste of raw materials. Although the extrusion-free mold at the present stage can solve this problem well, the mold processing technical requirements and processing costs are very high, and the use environment is harsh, so that it cannot be widely used. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the problem that the existing single-layer plastic pipe extrusion die cannot quickly adjust the concentricity of the plastic layer during the normal extrusion process...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome the problem that the existing single-layer plastic pipe extrusion die cannot quickly adjust the concentricity of the plastic layer during the normal extrusion process, resulting in a lot of waste of raw materials, and to overcome the single-layer extrusion mold processing technology. For the problem of high requirements and high cost, a single-layer plastic pipe extrusion fine-tuning die is provided, which reduces the adjustment time and waste of raw materials
