Abstract
The utility model relates to an 8-shaped optical cable protective cover extrusion molding die, comprising a mold core unit matched with the taper hole on the head of an extrusion machine and a mold cover unit connected to the end part of the outlet thereof. Two straight mold holes which are parallel in axial direction are provided in the direction of the outlet of the mold core body of the mold core unit. The mold cover unit is a mold cover body with the structure of a discharge hole. The molding die can be assembled on the head of a general extrusion machine according to the assembling mode of a common optical cable molding die, without replacing with a special-purpose head of an extrusion machine; therefore, a great amount of time of preparation for manufacture is saved, the labor intensity of workers is reduced, and the surface quality of the protective cover is improved.
Description
Technical field
The utility model relates to a kind of extruded mould of cable jacket, especially for the extruded mould of producing " 8 " font cable jacket.
Background technology
" 8 " font structure optical cable is a kind of aerial optical cable, is made up of two parts: the first half is a cable messenger, is to be made of steel wire rope; The latter half comprises that the cable core of being made up of a central buffer tube or many stranded separator tubes forms.Two parts are all coated by the pe sheath layer up and down.
" 8 " are though type structure optical cable is a kind of optical cable of special construction, but under normal conditions, the optical cable of it and ordinary construction is all produced on same sheath production line, and same extruding machine should be produced the optical cable of ordinary construction, produces " 8 " type structure optical cable again.But because " 8 " type optical cable and common single core type optical cable marked difference also structurally, thereby also there are bigger difference in head and the mould of producing these two kinds of optical cables.
For example, be the version of the handpiece structure of the highest production ordinary construction cable jacket of a kind of frequency of utilization and core rod wherein, die cap shown in the accompanying drawing 1.Its mold insert structure accurately is positioned in the internal taper hole; Die cap is installed in the end cap of head, and can the adjusting play, front and back.
Accompanying drawing 2 is a kind of special-purpose head and the moulds that are used for producing " 8 " type cable jacket at present.The structure of its head and mould wherein and ordinary optical cable sheath extrusion head and mould shown in Figure 1 have bigger difference, do not have the possibility of general exchange.Therefore when producing " 8 " type optical cable, must plain edition extruder head shown in Figure 1 be unloaded fully, and then change " 8 " type cable jacket special use extruder head shown in Figure 2 and special-purpose core rod, die cap.And each this dismounting, the process of reinstalling head and mould not only need to take a long time, and labor strength is big, simultaneously since this mould for squeezing tubular type, " 8 " type cable jacket surface quality of being produced is not high yet.
The utility model content
At above-mentioned situation, the utility model will provide a kind of novel " 8 " type cable jacket extruded mould that can have general interchangeability with ordinary optical cable sheath extrusion head commonly used, to solve the inconvenience and the unfavorable factor of present production " 8 " type cable jacket extruded mould.
The structure of the utility model " 8 " type cable jacket extruded mould, it is the die cap unit that has the core rod unit that can be matched with in the extrusion head internal taper hole and be connected in its outlet end, the Way out of core rod body is provided with the straight pattern hole of two axially parallels in the core rod unit, and the die cap unit is the die cap body that has the discharging opening structure.
In said structure, the said straight pattern hole that is arranged at two axially parallels of core rod body Way out side, except that can adopt with the core rod unit be the integrally-built form, more desirable mode, it is the location structure that adopts through appropriate format, for example be the structure that adopts the positioning pressuring plate formula in one embodiment, the version that is provided with in the assembling mode.A kind of version in back can help to improve the machining accuracy in this straight pattern hole and/or safeguard and change.
In like manner, said die cap unit in the said structure, have the monolithic construction of discharging opening structure except that adopting to be at die cap body outlet end, also can adopt to make this discharging opening structure, as be connected in the die cap unit of the fabricated construction of die cap body outlet end through fastening structures such as fastening bolt commonly used through fastening structure.Generally speaking, because the shape more complicated at discharging opening place, die cap unit, difficulty of processing is bigger, therefore for making it that processing technology preferably can be arranged, it is even more ideal that the die cap unit is designed to fabricated structure, has both helped guaranteeing precision, make again processing and/assembling is more convenient.
Obviously, a distinguishing feature of " 8 " type cable jacket extruded mould of the utility model said structure form, be exactly when producing " 8 " type cable jacket, can in the most frequently used general extruder head as shown in Figure 1, use, the installation method of its mould also is entirely identical to the mould of ordinary optical cable, need not to be replaced with again the special-purpose extruder head of at present used " 8 " type cable jacket, thereby can save a large amount of production times, and alleviated working strength of workers, after simultaneously mould being designed to squash type, the quality of jacket surface is improved.
Below mode by the specific embodiment that combines with accompanying drawing, foregoing of the present utility model is described in further detail again.But this should be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following example.Do not breaking away under the above-mentioned technological thought situation of the utility model, various replacements or change according to ordinary skill knowledge and customary means are made include in scope of the present utility model.
Description of drawings
Fig. 1 is that the head of present ordinary construction cable jacket reaches the wherein schematic diagram of core rod, die cap structure.
Fig. 2 is the present schematic diagram of the special-purpose head of " 8 " type structure cable jacket and middle core rod thereof, die cap structure.
Fig. 3 is the port of export view of the utility model " 8 " type cable jacket extruded mould.
Fig. 4 is the A-A structural representation of Fig. 3.
The specific embodiment
Fig. 1 and Fig. 2 are respectively the head and the structures of core rod, die cap wherein of the ordinary construction cable jacket of aforementioned present use, and the special-purpose head of " 8 " the type structure cable jacket that uses at present and the structure of core rod, die cap wherein.
Fig. 3 and Fig. 4 are the structures of " 8 " of the present utility model type cable jacket extruded mould, and its structure is made up of with the die cap unit that is connected in its port of export the core rod unit that has in the internal taper hole that can be matched with extrusion head.The core rod unit is formed with the straight pattern hole 5,6 of two axially parallels of the fastening setting of assembling mode through positioning pressuring plate 4 by core rod body 2 with in the Way out side of core rod body 2.Because it is very smooth that the processing difficulties in this straight pattern hole 5,6 is that the endoporus of its elongated nib requires, therefore with its as independent part processing well after, in the time of in being fit into core rod body 2, be fixed by positioning pressuring plate 4.The die cap unit is for forming by die cap body 1 and through the discharging opening structure 3 that some trip bolts 7 are connected in its outlet end.
When needs are produced " 8 " type optical cable, after only the core rod die cap of original production ordinary construction optical cable need being taken off, the core rod unit of directly that the utility model is above-mentioned " 8 " type optical cable is installed in the internal taper hole in the head tripper again, and then installs the die cap unit and get final product.
