Fig. 1 is the cross-sectional view of prior art extruder head;
Fig. 2 is the cross-sectional view of the utility model extruder head.
Detailed description of the invention
For describing technology contents of the present utility model in detail, realize object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
Refer to Fig. 2, the utility model extruder head comprises external mold 10, mouth mould 20, core 30, connecting cylinder 40, pressure mother 50, mesh plate 60 and plug 70.
External mold 10 is provided with open cavity 11.Core 30 is contained in open cavity 11, is formed with melting material runner 111 between open cavity 11 inwall of core 30 and external mold 10.
External mold 10 one end is fixedly connected with mouth mould 20, and external mold 10 other end is fixedly connected with connecting cylinder 40, and wherein open cavity 11 is communicated with the cylinder chamber of connecting cylinder 40.Connecting cylinder 40 is fixedly connected with extruder (not shown).
What deserves to be explained is, external mold 10 also can be integrally formed with connecting cylinder 40 and be fixedly connected with.
Preferably, described connecting cylinder 40 is detachably fixedly installed with external mold 10.Certainly, connecting cylinder 40 and external mold 10 also can be integrally formed.
Preferably, be provided with pressure female 50 outside described mouth mould 20, mouth mould 20 compresses and is fixed on external mold 10 by pressure female 50.
Mesh plate 60 is provided with through hole 61, and mesh plate 60 is fixed between the cylinder cavity wall of connecting cylinder 40, and for filtering the impurity of melting material, the axis that mesh plate 60 is preferably perpendicular to connecting cylinder 40 is arranged.
Core 30 one end is fixedly connected with mesh plate 60, and core 30 other end is fixedly connected with plug 70, and certainly, core 30 other end and plug 70 also can be integrally formed.In the present embodiment, the plate center of mesh plate 60 protrudes out and is provided with connecting portion 62, and one end that core 30 is connected with mesh plate 50 offers installing hole 31, and this connecting portion 62 is installed in installing hole 31, to complete being fixedly connected with of core 30 and mesh plate 60.Certainly, other any connected modes that core 30 and mesh plate 60 are fixed together.
