Abstract
The utility model relates to a forming device of a poly ethylene (PE) pipe and particularly relates to a feeding cavity of a poly ethylene (PE) pipe die head. The feeding cavity consists of a cavity wall and a core bar. The feeding cavity is characterized in that a spiral flow channel is arranged between the cavity wall and the core bar. Accordingly, a prior bar type flow channel is modified to the spiral flow channel, the compression ratio is increased, the plasticizing capacity of a PE die is improved and the pipe quality is improved.
Description
Technical field
The utility model relates to PE pipe former, especially a kind of PE pipe die head feed cavity.
Background technology
In PE pipe production process, the PE melt enters extrusion die after compressing by a section feeding chamber, then moulding, PE pipe die head feed cavity is built-in plug reduces the space that the PE material can pass through, reach compression PE material, improve the purpose of PE material plasticizing capacity, also between plug and feed cavity outer wall, isolated column is set vertically in the PE pipe die head feed cavity commonly used now, further strengthen the compression to the PE material, but effect is not ideal enough, need to improve.
Summary of the invention
The purpose of this utility model provides a kind of PE pipe die head feed cavity that can increase PE material compression ratio.
The utility model discloses a kind of PE pipe die head feed cavity, consisted of by chamber wall and plug, it is characterized in that being provided with between chamber wall and the plug spiral runner.
In the utility model, original bar runner is improved to spiral runner, increased compression ratio, improved the plasticizing capacity of PE die body, promoted pipe workpiece quality.
Description of drawings
Fig. 1 is cross-sectional view of the present utility model.
Fig. 2 is bar cross section of fluid channel figure.
1 is chamber wall, the 2nd among the figure, plug, the 3rd, runner.
The specific embodiment
As shown in Figure 1, 2, PE pipe die head feed cavity is made of chamber wall 1 and plug, it is characterized in that being provided with between chamber wall and the plug spiral runner.
In the utility model, original bar runner is improved to spiral runner, increased compression ratio, improved the plasticizing capacity of PE die body, promoted pipe workpiece quality.By experiment contrast, the compression ratio of bar runner is 1.26MPa/m before transforming
2, power consumption is 587.2 yuan/tons, melt flow 0.85Kg/s, and the compression ratio of transforming rear screw formula runner increases to 1.47MPa/m
2,, power consumption is reduced to 456.7 yuan/tons, and melt flow increases to 1.35Kg/s, and is energy-conservation and put forward effect obviously.
Claims (1)
1. a PE pipe die head feed cavity is made of chamber wall (1) and plug (2), it is characterized in that being provided with spiral runner (3) between chamber wall (1) and the plug (2).
