Extrusion molding, mould includes die cap and the core rod of split construction, first installs core rod, then installs die cap, adjust die cap during installation
With the distance between core rod and lock, installment work is relatively complicated, and die cap adjusts difficult, the mode transfer time with the concentricity of core rod
Long, affect production efficiency, and the pressure transient of dies cavity, affect stablizing of product appearance quality, fraction defective is high.
Utility model content：
The purpose of this utility model is to provide integral type jacket extrusion mould, stablize the distance between die cap and core rod,
Concentricity, facilitates mode transfer to install, improving production efficiency.
For reaching above-mentioned purpose, this utility model adopts the following technical scheme that：
Integral type jacket extrusion mould, this mould has die cap and core rod, and die cap is combined as a whole with core rod, and die cap with
It is provided with extrusion gap, the feeding mouth on the connecting mold of extrusion gap between core rod；Extrusion cavities are additionally provided with described die cap, on core rod
It is provided with the centre bore passing through for cable core, extrusion cavities and centre bore are coaxially disposed and are intersected in extrusion gap；The inner tool of described core rod
There is external screw thread, mould rotation is realized by external screw thread and puts into extruder head.
In such scheme, described extrusion gap is V-shaped, and extrusion cavities and centre bore are intersected in the V bottom in extrusion gap.
In such scheme, described centre bore is a round taper hole, and small end is towards extrusion cavities.
In such scheme, described feeding mouth is the groove structure positioned at die cap and core rod transition region.
In such scheme, the termination of described die cap is axially convexly equipped with round platform, round platform is provided with the face of scabbling of convenient rotation.
Integral type jacket extrusion mould of the present utility model, structure is simple, and die cap is relatively fixed with core rod, be derived from as
Lower beneficial effect：
1st, small volume, area occupied be prior art half, mould is put, manage more convenient.
2nd, easy for installation and quick, mould integral-rotation is realized by external screw thread and puts into extruder head.
3rd, centering accurately, need not adjust the degree of eccentricity, save the time of mode transfer, production efficiency is greatly improved, overcomes former
Mould, after installing die cap, needs material extrusion to observe the discharging direction of die orifice plastics, constantly pinches plastics with handss and adjusts up and down
The head screw of left and right four direction, thus adjusting the concentricity of die cap and core rod, plastics can be extruded from die orifice straightly
Defective mounting.
4th, according to technology Calculation and fixing die cap and core rod spacing, constant, the stable load of the pressure of dies cavity
Ensure that stablizing of product appearance quality, prevent the manual operation error that mode transfer each time produces and the presentation quality thing leading to
Therefore.
Brief description：
Accompanying drawing 1 is this utility model one example structure schematic diagram；
Accompanying drawing 2 is the internal structure schematic diagram of Fig. 1 embodiment.
Specific embodiment：
Below with reference to accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is made furtherly
Bright, to be fully understood from the purpose of this utility model, feature and effect.
Refering to shown in Fig. 1,2, being preferred embodiment structural representation of the present utility model, this utility model is about one kind one
Body formula jacket extrusion mould, this mould has die cap 1 and core rod 2, and die cap 1 is combined as a whole with core rod 2, can be connected by welding
Or be integrally machined.It is provided with extrusion gap 3, the feeding mouth 4 on the connecting mold of extrusion gap 3 between die cap 1 and core rod 2；Described
Extrusion cavities 11 are additionally provided with die cap 1, core rod 2 is provided with the centre bore 21 passing through for cable core, extrusion cavities 11 are coaxial with centre bore 21
Arrange and be intersected in extrusion gap 3, the spacing between extrusion cavities 11 and centre bore 21 is according to technology Calculation and fixing, to obtain mould
The pressure of tool inner chamber is constant, reaches stable load and ensure that stablizing of product appearance quality.Described core rod 2 the inner has outer
Screw thread 22, realizes mould rotation by external screw thread 22 and puts into extruder head, easy for installation and quick.
Fig. 1, shown in 2, in the present embodiment, described extrusion gap 3 is V-shaped, and extrusion cavities 11 and centre bore 21 are intersected in crowded
Go out the V bottom in gap 3, pressure is constant, so that after cable core passes through centre bore 21, the plastics tight of the V bottom in extrusion gap 3
Cable core, then extrude together from extrusion cavities 11, make sheath, jacket structure dimensionally stable.Described centre bore 21 is a round taper hole,
Small end, towards extrusion cavities 11, is easy to guide cable core, effectively prevents from extruding the plastics backflow in gap 3 simultaneously.Feeding mouth 4 be positioned at
Die cap 1 and the groove structure of core rod 2 transition region, structure is simple, facilitates the charging on connecting extruder head after putting into extruder head
Mouthful, easy for installation and quick.Axially it is convexly equipped with round platform 12, round platform 12 is provided with cutting of convenient rotation on the termination of described die cap 1
Plane 121, easy disassembly mould.
This utility model is applied to produce, and production efficiency is greatly improved.Die cap 1 is integrated with core rod 2, former in guarantee
