In order to solve the technical problem, the following technical proposal is adopted: the non-stop die changing device of the middle-high voltage cross-linked cable production line comprises an extrusion die provided with an inner die; a die sheathing hole is arranged in the inner die and internally provided with a small die in a movable manner; and the small die has a vertical bisect structure. Compared with the prior art, the non-stop die changing device has the advantages of simple structure, easy operation, small waste volume of die, energy conservation and reliable performance.
Description
Technical field
What the present invention relates to a kind of crosslinked cable production line does not shut down mould changing device, especially a kind of mesohigh crosslinked cable production line do not shut down mould changing device.
Background technology
The three-layer co-extruded continuous crosslinked unit of the many employings of the insulation extrusion process of mesohigh crosslinked cable at present, its great advantage is exactly a continuous extruded and crosslinked, carries out length production.The crosslinked unit of this pattern all has the cross-linking tube that reaches about 200m usually, so each start and stop car of this unit, its expense is surprising.According to measuring and calculating, crosslinked unit opens car about 200m that need go between at every turn, the minimum 20m that needs of the insulation tuningout heart.In addition, debug and need 150m approximately, waste nearly 60m conductor wire core at every turn when stopping again for satisfying process conditions.Therefore, the each start and stop car of crosslinked unit only conductor wire core just needs waste 450m, wherein with the about 300m of the core of plastic rubber material.This shows that reduce start and stop train number number is the most effectual way that reduces product cost as far as possible.If realizing the conductor wire core of adjacent-specification does not stop mold exchange and carries out continual, continuous length production, so just can reduce start and stop train number number, reduce greatly that insulation comprises that conductor screen and insulation shielding extrude and crosslinking process in to raw-material consumption, and can reduce energy consumption and enhance productivity, be a kind of very effective method that reduces production costs.
In the day for announcing is that the inventor attempts not shutting down mould changing device, is provided with the cover nib in internal mold in the mould changing device of Chinese utility model CN200720122079.0 crosslinked cable production line on June 11st, 2008, is socketed with little mould in the cover nib.But because used little mould employing is cannula-like, in actual production, also to from internal mold, take out little mould during die change and cut, could take off die change again from lead, and mould uses and once just can not re-use, cause the waste of mould, and when little mould threading, also to walk very long distance from the unwrapping wire threading, cause waste of time.Therefore, technique scheme also exists improved requirement.
Summary of the invention
What the technical problem to be solved in the present invention provided a kind of mesohigh crosslinked cable production line does not shut down mould changing device, is implemented in the mesohigh crosslinked cable production process die change and does not shut down.
For solving the problems of the technologies described above; the present invention is by the following technical solutions: a kind of mesohigh crosslinked cable production line do not shut down mould changing device; comprise the extrusion head that is provided with internal mold, be provided with the cover nib in the described internal mold, movable sleeve is connected to vertical little mould to opening structure in the described cover nib.
Cover nib of the present invention is arranged on the head of internal mold, and the external diameter shape of described little mould is suitable with the cover nib.
Cover nib of the present invention is a truncated cone-shaped, and the outer wall of described little mould is a truncated cone-shaped.
The vertical of little mould of the present invention is up big and down small tongue and up-small and down-big groove occlusion structure to opening structure.
The cross sectional shape of tongue of the present invention and groove is suitable trapezoidal or circular.
Vertical outer cross sectional shape of internal mold of the present invention is conical, and interior cross sectional shape is a truncated cone.
Be equipped with lead in the little mould of the present invention.
Internal mold of the present invention and little mould are the structure that is closely connected.
The internal diameter of little mould of the present invention is 6.0mm to 42.3mm.
The internal diameter of little mould of the present invention is 20.6mm.
The present invention compared with prior art by adopting the cover die device to opening structure, is implemented in the mesohigh crosslinked cable production process die change and does not shut down, and is simple in structure, easy to operate, the mould wastage is little, and have save time, the characteristics of dependable performance.

Embodiment
Below in conjunction with drawings and Examples the present invention is described in further detail.
Shown in Fig. 1,1-1,2 and 3, a kind of mesohigh crosslinked cable of the present invention production line do not shut down mould changing device, comprise the extrusion head 1 that is provided with internal mold 2; be provided with the cover nib in the internal mold 2; movable sleeve is connected to little mould 3 in the cover nib, and little mould 3 to opening structure, is equipped with lead 5 in the little mould 3 for vertically.Wherein, the cover nib is arranged on the head of internal mold 2, and the external diameter shape of little mould 3 is suitable so that internal mold 2 forms the structure that is closely connected with little mould 3 with the cover nib.As a specific embodiment of the present invention, vertical outer cross sectional shape of internal mold 2 is conical, and interior cross sectional shape is a truncated cone.Cover nib in the internal mold 2 is a truncated cone-shaped, and the outer wall of little mould 3 then is the fit shapes of truncated cone-shaped.
As shown in Figure 4, little mould of the present invention be up big and down small tongue and up-small and down-big groove occlusion structure vertically to opening structure, the cross sectional shape of tongue and groove can also can adopt circle or other occlusion structure for suitable trapezoidal.
The internal diameter of little mould of the present invention is 6.0mm to 42.3mm, can make the little mould of different inner diameters according to producing needs, and for example internal diameter is the little mould of 6.0mm, 20.6mm or 42.3mm, is used for the production of different size cable.
When the present invention installs, internal mold 2 is set in extrusion head 1 at first, is provided with the cover nib in the internal mold 2, the little mould 3 of socket in the cover nib.The position at internal mold 2 places is C place among Fig. 1, and Fig. 1-1 is the extrusion head 1 that amplify at the C place among Fig. 1, and Fig. 3 is the little mould 3 to opening structure after amplifying, and its position is A place among Fig. 2.To take out the little mould 3 of the opening structure C from extrusion head 1 when changing production specification, and change the little mould 3 of splitting of required production specification again and get final product, the position that little mould 3 is understood with 2 li of C place internal molds matches, thereby die change is not shut down in realization.
The present invention transforms the little mould in the former internal mold, and the cannula-like structure that it is original changes Advance paired opening structure (as shown in Figure 4), and two mutual interlocks of the semicircle band of column of vertically splitting, Make syndeton more reliable and more stable, the little mould that will split again is by the dimensions design of need of production Good. To split little mould during production and penetrate in the specification that to produce at the extrusion head place, bring internal mold into The middle good position of car, and combine closely, thereby reach the effect of not shutting down, need not unload original mould. Compared with prior art, the present invention have easy to operate, save mould, timesaving characteristics.
