Abstract
The utility model relates to a self-centering mold of an optical cable sheath plastic extruding machine, which comprises a mold sleeve and a mold core, wherein the mold sleeve is fixedly connected to the mold core. The mold sleeve is provided with a discharging hole and a mold sleeve cavity, the discharging hole is communicated with the mold sleeve cavity, the mold core is provided with a cable core hole and a mold core cavity, and the cable core hole is communicated with the mold core cavity. A plurality of diversion grooves are arranged on the circumference of the mold core, and at least part of the mold core extends into the mold sleeve cavity. The self-centering mold of the optical cable sheath plastic extruding machine has the advantages that the mold sleeve is fixedly installed on the mold core, the central axes of the mold sleeve and the mold core are coincided, and the mold sleeve does not need to be adjusted during running. The diversion grooves are evenly distributed on the circumference of the mold core, thereby enabling sheath materials to be evenly extruded out from the gap between the mold core and the mold sleeve, and guaranteeing that the extruded optical cable sheath is not eccentric.

In order to overcome the defective that exists in the background technology, the technical scheme that its technical matters that solves the utility model adopts is: a kind of cable jacket extruding machine self centering mould, comprise die sleeve and core rod, described die sleeve is fixedly connected on the core rod, described die sleeve is provided with discharge opening and die sleeve chamber, described discharge opening is connected with the die sleeve chamber, described core rod is provided with cable core hole and mold core cavities, described cable core hole is connected with mold core cavities, described core rod circumference is provided with some diversion trenchs, and described core rod to small part stretches into the die sleeve chamber.
According to another embodiment of the present utility model, a kind of cable jacket extruding machine self centering mould further comprises between described core rod and the die sleeve for being threaded.
According to another embodiment of the present utility model, a kind of cable jacket extruding machine self centering mould comprises that further described core rod stretches into place, die sleeve chamber and forms cavity, and described cavity is connected with discharge opening, diversion trench respectively.
According to another embodiment of the present utility model, a kind of cable jacket extruding machine self centering mould further comprises the central axes of the central axis and the core rod of described die sleeve.
According to another embodiment of the present utility model, a kind of cable jacket extruding machine self centering mould comprises that further described diversion trench circumferentially evenly distributes.
The utility model has solved the defective that exists in the background technology, and die sleeve is fixedly mounted on the core rod, their central axes, and in the time of work, die sleeve need not to adjust; Diversion trench evenly distributes on circumference, makes protective cover material to extrude the gap between core rod and die sleeve equably, has guaranteed that the cable jacket of extruding is not eccentric.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the cut-open view of the structure of preferred embodiment of the present utility model;
Wherein: 1, die sleeve, 2, core rod, 3, discharge opening, 4, the die sleeve chamber, 5, the cable core hole, 6, mold core cavities, 7, diversion trench, 8, cavity.
Embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the synoptic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As Figure 1-3, a kind of cable jacket extruding machine self centering mould, comprise die sleeve 1 and core rod 2, described die sleeve 1 is fixedly connected on the core rod 2, and described die sleeve 1 is provided with discharge opening 3 and die sleeve chamber 4, and described discharge opening 3 is connected with die sleeve chamber 4, described core rod 2 is provided with cable core hole 5 and mold core cavities 6, described cable core hole 5 is connected with mold core cavities 6, and described core rod 2 circumference are provided with some diversion trenchs 7, and described core rod 2 to small part stretches into die sleeve chamber 4.
As shown in Figure 2, described core rod 2 ends are provided with screw thread 7, and are fixedly connected by screw thread between described core rod 2 and the die sleeve 1.
In this practicality, core rod 2 stretches into 4 places, die sleeve chamber and forms cavity 8, described cavity 8 is connected with discharge opening 3, diversion trench 7 respectively, and promptly core rod 2 is provided with certain clearance with die sleeve chamber 4 in installation process, can guarantee that like this protective cover material extrudes from the gap between die sleeve 1 and the core rod 2.
This practical die sleeve 1 and core rod 2 should notice that when mounted the cable core hole 5 on the core rod 2 will insert in the discharge opening 3 of die sleeve 1, and the central axis of assurance die sleeve 1 and the central axes of core rod 2, guarantee that promptly die sleeve 1 is concentric with core rod 2, thereby guarantee that sheath is not eccentric.
Shown in Fig. 2-3, described core rod 2 circumference are provided with some diversion trenchs 7, and described diversion trench 7 circumferentially evenly distributes, and can guarantee that like this protective cover material can evenly extrude the gap between core rod 2 and die sleeve 1 equably, thereby sheath is not eccentric when guaranteeing out die orifice.
The installation and the course of work of cable jacket extruding machine self centering mould of the present utility model are: core rod 2 be installed on the cable jacket extruding machine, then die sleeve 1 be installed on the core rod 2, and fixedly connected between them by screw thread.In the installation process of die sleeve 1 and core rod 2, notice that cable core hole 5 and discharge opening 3 should be in the center, and the front end face in cable core hole 5 and the front end face of discharge opening 3 are on the plane.During the beginning extrusion molding, cable core passes mold core cavities 6, cable core hole 5 and discharge opening 3 successively, after the plastics of fusion are pushed out from the spiral shell thorax, enter from die sleeve chamber 4 and to be extruded on the cable core, from the diversion trench 8 of core rod 2, extrude again, go out die orifice the gap between core rod 2 and die sleeve 1 at last.Diversion trench 7 is divided into equally distributed three parts on circumference, thereby the plastic sheath material can extrude the gap between core rod 2 and die sleeve 1 equably, thereby sheath is not eccentric when guaranteeing out die orifice.In the mould of this patent, die sleeve 1 is fixed on the core rod 2, during work, need not do any adjustment.
