Fig. 1 is the structural representation of the extrusion molding apparatus for moulding three wall corrugated pipes of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, extrusion molding apparatus 400 for moulding three wall corrugated pipes of the present utility model, comprise interior die body 410 and outer die body 420, described interior die body 410 and outer die body 420 are hollow structure, described interior die body 410 is arranged on the inboard of described outer die body 420, the inboard of described interior die body 410 is coated on the double-wall corrugated pipe 10 of double-walled corrugated pipe forming machine output, described interior die body 410 is connected to each other with outer die body 420 and section's be formed for circulating first flow 430 of material within it, be provided with charging aperture 440 at described outer die body 420, described charging aperture 440 is communicated with described first flow 430, the front end of described interior die body 410 is provided with core 450, the front end of described outer die body 420 is provided with mouthful mould 460, consist of the second runner between described core 450 and mouthful mould 460, described the second runner is connected with described first flow 430, in described outer die body 420 arranged outside heating system 480 is arranged.
Described outer die body 420, interior die body 410, mouthful mould 460 and core 450 are circular circulus, and the internal diameter of described outer die body 420, interior die body 410, mouthful mould 460 and core 450 is greater than the external diameter of described double-wall corrugated pipe 10.
Described the second runner and described extrusion molding apparatus 400 to extrude direction in an acute angle, the angle of described acute angle is the 15-55 degree.
