Detailed description of the invention
The present invention is described in detail below by the embodiment shown in below in conjunction with the accompanying drawings:
As shown in accompanying drawing 1 to accompanying drawing 3, a kind of side feed auger formula continuous extrusion-blown modling die head, tie including layer structure and internal layer
Structure, described layer structure includes axially connecting outer die casing 1, regulation ring 2 and mouth die 3, the described endothecium structure installed successively
Including axially connecting lifting rod 4 and the core 5 of installation, described outer die casing 1, regulation ring 2 and described mouth die 3 are in axle center
Empty structure, described lifting rod 4 closes in described outer die casing 1 and described regulation ring 2, and described core 5 closes at described
Mouth die 3 in, the periphery wall of described lifting rod 4 be arranged with can the shunting helix core 13 of axially opposing movement, described point
Material flow path 6 is formed between stream helix core 13 and the outside wall surface of described both cores 5 and the internal face of described layer structure,
The outside wall surface of described shunting helix core 13 offers material trough, and this material trough includes feed well 7 and a plurality of parallel spiral
Material-dividing groove 8, each described screw material-distributing groove 8 connects with described feed well 7 respectively, and described screw material-distributing groove 8 is the most flat
Row is arranged.
