Specific implementation mode
The utility model technical solution claimed is done further specifically in conjunction with the drawings and specific embodiments
It is bright.
Shown in Fig. 1 to Fig. 4, a kind of screw extruder die head for plastic barrel production in the present embodiment, including
Interior die orifice 1, outer die orifice 2, mold core 3, hydraulic cylinder 4 and outer sleeve 5.
Wherein mold core 3 is set to inside outer sleeve 5, and hydraulic cylinder 4 includes cylinder body 41 and runs through cylinder body about 41 two simultaneously
The piston rod 42 at end, 42 lower end of the piston rod is fixedly connected with mold core 3 to be lifted with band moving-mould-core 3 along outer sleeve 5, the mold core 3
Runner 6 between 5 inner wall of outer sleeve there are gap to be formed is also associated with the feed pipe 9 of connection runner 6 outside outer sleeve 5
To input the molten plastic of screw extruder, screw extruder die head is docked with screw extruder in the present embodiment, basis
Fluid is flowed along above-mentioned runner 6.
The interior die orifice 1 is fixedly connected on 3 lower end of mold core, and the outer die orifice 2 is fixedly connected on 5 lower end of outer sleeve, wherein
Interior die orifice 1 and the inside and outside arrangement of outer die orifice 2, and there are gaps to be formed and the stream between 2 inner wall of 1 outer wall of interior die orifice and outer die orifice
The tapping channel 7 that road 6 is connected to；5 lower peripheral of outer sleeve is threaded at least three pieces of radial clearances and adjusts in the present embodiment
Bolt 21, outer 2 periphery of die orifice of each 21 top pressure of radial clearance adjusting bolt is simultaneously radially extended along outer die orifice 2, corresponding by screwing
Radial clearance adjusting bolt 21 drives die orifice 2 outside its top pressure to move along the radial thus in adjusting between die orifice 1 and outer die orifice 2
Concentricity makes the even width everywhere in same level of tapping channel 7.7 downside longitudinal section of tapping channel is in inverted V-shaped structure
And the longitudinal section width of tapping channel 7 is tapered downward, and by die orifice in lifting 1 to adjust the longitudinal section width of tapping channel 7,
Specifically, it is lifted with moving-mould-core 3 by the piston rod 42 of hydraulic cylinder 4, and then interior die orifice 1 is driven to lift, work as internal model
Mouth 1 rises, and the longitudinal section width that the gap between interior die orifice 1 and outer die orifice 2 reduces material channel reduces, and is flowed from tapping channel 7
The extrusion body thickness gone out reduces；When interior die orifice 1 declines, the longitudinal section in channel is expected in the gap increase between interior die orifice 1 and outer die orifice 2
Width increases, and the extrusion body thickness flowed out from tapping channel 7 increases.In process of production, it is adjusted in real time using hydraulic cylinder 4
Body thickness is squeezed out to change plastic barrel（Product）Wall thickness.
