Abstract
The utility model relates to a kind of cable jacket mould inner mould.The jacket mould internal mold that object is to provide should be able to guarantee the coated quality of aluminium foil, and have structure simple, make the feature of being easy to.Technical scheme is: a kind of cable jacket mould inner mould, its conical outer surface and bellmouth coaxially arranged; It is characterized in that: the large nose end of described bellmouth fixes the sleeve pipe of a conveying semi-finished product cable by connecting internal thread.
Description
Technical field
The utility model relates to a kind of production equipment of cable, specifically the jacket mould of cable.
Background technology
Last procedure of cable production process is at semi-finished product cable (being coated with insulating barrier and aluminium foil layer successively in inner wire outside from inside to outside) outside injection moulding sheath.This work is carried out on injection-moulding device; Be coated with the jacket mould internal mold of heart yearn through injection-moulding device of aluminium foil, the protective cover material of thawing is coated outside at aluminium foil, then enters the cold sheath that makes of tank and shapes.
Conventional jacket mould is made up of external mold and the internal mold of inserting external mold cavity; Wherein to be manufactured with bellmouth (bellmouth right-hand member aims at the parts carrying semi-finished product cable) in internal mold, semi-finished product cable is turned left by the right side and is moved into bellmouth and exports from the little port part of bellmouth; The outer surface of internal mold is taper, and the protective cover material melted in external mold cavity flows along the outer surface of internal mold toward left end, constantly lays and is coated on the surface of the semi-finished product cable exported from the little port part of bellmouth.Because the parts (mould for longitudinal wrapping of aluminium foil) of conveying semi-finished product cable are spaced a distance (usually distance about 1 meter) with the bellmouth rear portion of internal mold; So semi-finished product cable axis is difficult to aim at the axis of conical internal cavity, cause the thickness degree varies of sheath circumference, and aluminium foil is inconsistent at the tightness on heart yearn surface, directly affects the product quality of sheath and cable.
Utility model content
The purpose of this utility model overcomes the deficiency in above-mentioned background technology, provides a kind of improvement of jacket mould internal mold, and this jacket mould internal mold should be able to guarantee the coated quality of aluminium foil, and have structure simple, make the feature of being easy to.
The technical solution of the utility model is: a kind of cable jacket mould inner mould, its conical outer surface and bellmouth coaxially arranged; It is characterized in that: the large nose end of described bellmouth fixes the sleeve pipe of a conveying semi-finished product cable by connecting internal thread.
The length of described sleeve pipe is 10-30cm.
The internal diameter of described sleeve pipe is identical with cable diameter.
The beneficial effects of the utility model are:
Owing to being configured with the sleeve pipe of a conveying semi-finished product cable at the large nose end of bellmouth, after semi-finished product cable enters sleeve pipe, naturally the dead in line of axis and bellmouth is adjusted to, ensure that semi-finished product cable is in the center of bellmouth all the time, also just ensure that the sheath in finished product has evenly unified thickness, and coated aluminium foil tightness is consistent; And then significantly improving the quality of cable, the generation eliminating inferior grade cable may.

Fig. 2 is left TV structure schematic diagram of the present utility model.
Fig. 3 is the main TV structure schematic diagram of existing jacket mould internal mold.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail.
Cable jacket mould shown in Fig. 1, is made up of external mold (omitting in figure) and the internal mold 1 of inserting external mold cavity; Wherein the outer surface 3 of internal mold is tapered, is also manufactured with bellmouth 2 (bellmouth right-hand member aim at carry the parts of semi-finished product cable) and layout corresponding with conical outer surface (being small end to turn left, hold greatly to turn right and arrange) in internal mold; Bellmouth also overlaps with the axis of conical outer surface.Above structure and existing jacket mould internal model structure (shown in Fig. 3) are roughly the same.
Improvement of the present utility model, be make internal thread 2-1 at the large nose end of described bellmouth, another making one sleeve pipe 5, the end of sleeve pipe makes the external screw thread with aforementioned screw-internal thread fit; After this sleeve pipe is fixed on the large end of internal mold by screw thread, semi-finished product cable just can input internal mold from sleeve pipe.Like this, originally some sagging semi-finished product cable enters internal mold under the holding of sleeve pipe, cannot centering and then the problem that causes sheath peripheral thickness inconsistent with regard to efficiently solving semi-finished product cable and internal mold, also the tightness making the aluminium foil of semi-finished product cable surface coated is consistent, and product quality is highly improved.
The length of described sleeve pipe can be determined as required, and length of recommended is 10-30cm.The internal diameter of sleeve pipe usually can be identical with cable diameter (comprising the diameter after sheath); During use, because semi-finished product cable does not have sheath, thus semi-finished product cable and casing inner diameter have certain interval, can not increase the resistance of motion of semi-finished product cable.
Claims (3)
1. a cable jacket mould inner mould, its conical outer surface (3) and bellmouth (2) coaxially arranged; It is characterized in that: the large nose end of described bellmouth fixes the sleeve pipe (5) of a conveying semi-finished product cable by connecting internal thread (2-).
2. cable jacket mould inner mould according to claim 1, is characterized in that: the length of described sleeve pipe is 10-30cm.
