Abstract
The utility model discloses an interchangeable combined type glass fiber wire positioning head which comprises a tail part substrate (1) and a front part component (2), wherein the front part component (2) and the tail part substrate (1) are in threaded connection; a threading hole (3) is arranged in the tail part substrate (1); and a combination hole is arranged in the front part component (2). In the utility model, due to the combined structure of the tail part substrate and the front part component, if the small hole is blocked by rubber material, the front part component is dismantled, and the blockage in the small hole can be cleared by a small iron wire, being very convenient. Meanwhile, the damageable positioning structure at the front end can be processed into an interchangeable high-precision component; and if the small hole is blocked by rubber material which cannot be cleared, the mould function can be recovered simply by replacing the front part component, thereby improving the using efficiency of the mould and reducing the repair rate. According to the utility model, the maintenance workload and the production cost are reduced.
Description
Technical field
the utility model relates to a kind of interchangeable combined type glass-fiber line positioning head, belongs to the processing tool technical field of rubber weather strip.
Background technology
have a positioning head in the extruder die when extruding with the groove of glass wire, be used for being positioned at the glass wire that need penetrate in the groove.Existing positioning head is an overall structure, and there are two through wires holes positioning head inside, and existing through wires hole is long taper hole; Only there is 0.8mm in the aperture of the threading outlet of taper hole front end, and sizing material usually can get into and cause obstruction in the through wires hole in the production process, because existing through wires hole is elongated tapered openings; Stop up the back and remove very difficulty, usually can cause positioning head to scrap in advance, need often to change positioning head owing to removing; Both increase maintenance workload, also improved production cost.
Summary of the invention
The purpose of
the utility model is, a kind of interchangeable combined type glass-fiber line positioning head is provided.Solve existing positioning head easy blocking, the technical problem of inconvenience cleaning.
The technical scheme of the utility model
a kind of interchangeable combined type glass-fiber line positioning head comprises afterbody matrix and front assembly two parts, and front assembly is threaded with the afterbody matrix; Be provided with through wires hole in the afterbody matrix, be provided with combination bore in the front assembly.
In
aforementioned interchangeable combined type glass-fiber line positioning head, the through wires hole on the said afterbody matrix is long straight hole.
In
aforementioned interchangeable combined type glass-fiber line positioning head, the combination bore on the said front assembly is made up of straight hole section and taper hole section; The end that combination bore is connected with the afterbody matrix is the straight hole section, and the other end of combination bore is the taper hole section; The small-bore aperture that is positioned at combination bore of taper hole section.
In
aforementioned interchangeable combined type glass-fiber line positioning head, an end of said through wires hole is provided with internal thread, and front assembly is provided with external screw thread, and the internal thread of external screw thread on the front assembly and through wires hole one end spins.
compared with prior art; The utility model is owing to the combining structure of having taked afterbody matrix and front assembly, in case after aperture is stopped up by sizing material, only need front assembly is unloaded; Tamper in the aperture can be removed with tiny iron wire, and is very convenient.The positioning head of the utility model front end rapid wear can be processed into the precision components with interchangeability simultaneously; When aperture can't be removed by the sizing material obstruction; Only need front assembly be changed and to recover functional die, improve the service efficiency of mould, reduce repair rate.Maintenance workload and production cost have been reduced.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the prior art constructions sketch map.
Being labeled as in
accompanying drawing: 1 – afterbody matrix, 2-front assembly, 3-through wires hole, 4-straight hole section, 5-taper hole section.
The specific embodiment
are further described the utility model below in conjunction with accompanying drawing and embodiment, but not as the foundation to the utility model restriction.
embodiment.
a kind of interchangeable combined type glass-fiber line positioning head, as shown in Figure 1.Comprise afterbody matrix 1 and front assembly 2 two parts, front assembly 2 is threaded with afterbody matrix 1; Be provided with through wires hole 3 in the afterbody matrix 1, be provided with combination bore in the front assembly 2.Through wires hole 3 on the said afterbody matrix 1 is long straight hole.Combination bore on the said front assembly 2 is made up of straight hole section 4 and taper hole section 5; The end that combination bore is connected with afterbody matrix 1 is a straight hole section 4, and the other end of combination bore is a taper hole section 5; The small-bore aperture that is positioned at combination bore of taper hole section 5.One end of said through wires hole 3 is provided with internal thread, and front assembly 2 is provided with external screw thread, and the internal thread of external screw thread on the front assembly 2 and through wires hole 3 one ends spins.
During
practical implementation; Can utilize existing positioning head (see figure 2); By shown in Figure 1; With existing positioning head front end near one section cone amputation at wire hole place as afterbody matrix 1, with drill bit the through wires hole on the afterbody matrix 3 is expanded into straight hole, then one section internal thread of processing on the straight hole of truncated position.Reprocessing front assembly 2; One section external screw thread of processing is connected with internal thread on the straight hole on the front assembly 2; Forwardly process combination bore on the axis of assembly 2, combination bore comprises straight hole section 4 and taper hole section 5, and a section of being connected with afterbody matrix 1 is a straight hole section 4; The other end is a taper hole section 5, the small-bore aperture that is positioned at combination bore of taper hole section 5.Be connected the external screw thread on the front assembly 2 with internal thread on the afterbody matrix 1 at last.During processing front assembly 2, its size and tolerance considered interchangeability are to be convenient for changing.
