Group, the module is installed on the connecting seat of connection extruding machine, and is characterized in that：The shaping mould is descending according to diameter
Laminated structure is installed on connecting seat, and the shaping mould includes shaping mould I, a diameter of d2s of a diameter of d1 located at inner side located at centre
The shaping mould II and a diameter of d3 of position are located at the shaping mould III, d1 in outside>d2>d3.
In said structure, a kind of extruder die module of the present invention includes multiple descending shapings for being sequentially overlapped installation
Mould, the shaping mould is dismantled and assembled, as long as unloading the shaping mould on the outside of the shaping mould that will be used when changing larger shaping cover
, it is not necessary to it is reinstalled (and need to only be loaded onto when changing less shaping cover, without unloading original shaping mould).
In order to realize above-mentioned connected mode, connecting seat is fixedly installed on the inside of the shaping mould I outer rings I and inner core I, it is another
Face is connected with shaping mould II, and the shaping mould II outer rings II is fixedly installed on the outside of the I of outer ring, and inner core II is fixedly installed in inner core I
Outside, the shaping mould III outer rings III inner sides are fixedly installed in outer ring II, and inner core III is fixedly installed in inner core II.
Further, it is threaded connection between the shaping mould to be threadedly coupled between the module and connecting seat, it is described
Outer ring and inner core are equipped with attachment structure, and the inner core I, outer ring I, inner core II and outer ring II are provided with two groups of connecting holes, made respectively
Fixed with the structure of they and both sides, the inner core III and outer ring III are provided with one group of connecting hole, make its shaping mould with inner side
II is connected.
In order that the tube surfaces of shaping are more smooth, grooving is left between the inner core and outer ring, the grooving is
Circle, the inner core excircle and outer ring inner periphery are provided with is made smooth contact ring using the relatively low material of surface roughness.
Beneficial effects of the present invention：
1st, in a kind of extruder die structure of the present invention, extrusion die includes multiple descending being sequentially overlapped determining for installation
Jacket, the shaping cover is dismantled and assembled, is convenient for changing.
2nd, in a kind of extruder die structure of the present invention, the die head shaping cover used is provided with smooth contact ring, smooth to connect
Touch ring to be made of the relatively low material of surface roughness, and be not limited to use and die head identical material, it is crowded so as to reduce
Mould the roughness of pipe.
