Abstract

The utility model relates to a novel sizing mold and belongs to the technical field of plastic processing. The sizing die comprises a machine head body, a shunting shuttle, an inner die, a core die and a mouth die combination body, wherein the right end of the machine head body is fixedly connected with the mouth die combination body; a cavity of the machine head body is internally provided with the shunting shuttle and the inner die in sequence from the left to right; the right end of the inner die is fixedly connected with the core die; the core die is positioned in the mouth die combination body; a gap is formed between the mouth die combination body and the core die; and the tail of the core die is axially provided with trip-shaped grooves uniformly distributed. According to the novel sizing die, the tail of the core die is axially provided with the strip-shaped grooves uniformly distributed, so that the inner wall of a manufactured silicon-core pipe is an inner wall with the axial strip-shaped grooves, and the contact area of an optical cable and the inner wall of the silicon-core pipe in the cable blowing process is lowered, thus the friction is reduced, the cable blowing speed is increased and the cable blowing stability is enhanced. The problems which are easily caused and are not implemented in the cable blowing process in the prior art, such as the large contact area of an existing optical cable and the inner wall of the silicon-core pipe, can be thoroughly solved. The novel sizing mold has the advantages that the structure is simple, the operation is safe and convenient, the cable blowing speed is increased and the cable blowing stability is enhanced.

Description

A kind of novel plug die

Technical field

The utility model relates to a kind of novel plug die, belongs to technical field of plastic.

Background technology

HDPE silicon core pipe is mainly as optical cable outside protective pipe, and in the communications field, application is very extensive.Optical cable, in covering process, first will be protected pipeline silicon core pipe to lay, and then adopt air-blowing mode to penetrate in silicon core pipe on optical cable.Owing to producing the plug die core mould surface of silicon core pipe, be flat, the silicon core pipe product inwall of producing is smooth smooth.In wearing cable work progress, when optical cable core penetrates silicon core pipe, because optical cable surface is larger with the contact area of silicon core inside pipe wall, coefficient of friction is higher, make optical cable in wearing cable process, be subject to larger resistance.Add it is that long distance is blown cable, a silicon core length of tube is generally 1000～2000 meters, so often there will be optical cable and silicon core inside pipe wall contact area greatly and resistance increment, causing blowing cable process, cannot to implement, wear cable speed slower, the situation that working efficiency is not high.The smooth structure of plug die core mould also makes to consume the function material quantity that price is higher in pipe material inner wall forming process to be increased, and causes product holistic cost to rise, the obvious competitive advantage of product nothing on market.

Summary of the invention

The purpose of this utility model is, providing a kind of axially digs and has uniform bar groove at sizing core mould afterbody, make the inwall of the cooling rear pipe of silicon core pipe form the inwall with axial striped groove, to solve silicon core pipe that existing plug die produces optical cable and silicon core inside pipe wall contact area is large, frictional force is high in work progress, cause blowing the problem that cable process cannot be implemented; And simple in structure, easy-to-operate, product cost can reduce by 5～8% novel plug die on original basis.

The utility model is to realize by the following technical solutions above-mentioned purpose:

This novel plug die consists of handpiece body, spreader, internal mold, core and a mouthful module zoarium, it is characterized in that: the right-hand member of handpiece body is connected with a mouthful module zoarium, spreader and internal mold are housed in the cavity of handpiece body from left to right successively, the right-hand member of internal mold is connected with a core, core is placed in mouthful module zoarium, between mouth module zoarium and core, be formed with gap, the afterbody of described core is axially manufactured with uniform bar groove.

The utility model beneficial effect is compared with prior art:

This novel plug die is axially manufactured with uniform bar groove at core afterbody, make the inwall of the cooling rear pipe of silicon core pipe produced be formed with the inwall with axial striped groove, optical cable and silicon core inside pipe wall contact area in blowing cable process are diminished, thereby reduced frictional force, improved and blown cable speed and stability, thoroughly solved the existing problem that the normal appearance of cable process cannot be implemented of blowing.And simple in structure, easy-to-operate, product cost has reduced by 5～8% on original basis.

In figure: 1, handpiece body, 2, spreader, 3, internal mold, 4, core, 5, mouthful module be fit, 6, bar groove.

The specific embodiment

This novel plug die consists of handpiece body 1, spreader 2, internal mold 3, core 4 and a mouthful module zoarium 5, the right-hand member of handpiece body 1 is connected with a mouthful module zoarium 5, spreader 2 and internal mold 3 are housed in the cavity of handpiece body 1 from left to right successively, the right-hand member of internal mold 3 is connected with a core 4, core 4 is placed in mouthful module zoarium 5, between mouth module fit 5 and core 4, be formed with gap, the afterbody of described core 4 is axially manufactured with uniform bar groove 6(and participates in accompanying drawing 1～2).

The course of work of this novel plug die is, when material enters handpiece body 1, through carrying out material diversion in spreader 2 places, then between the gap of internal mold 3, arrival core 4 and mouthful module zoarium 5, axial bars groove 6 from core 4 afterbodys flows out, and cooling rear formation is with the silicon core pipe product of axial striped groove 6.This novel plug die has solved in wearing cable work progress, the problem that optical cable and silicon core inside pipe wall contact area are large, thus reduced frictional force, improved and blown cable speed and stability, reduced product cost, product cost can reduce by 5～8% on original basis.

The above is preferred embodiment of the present utility model, above-mentioned not illustrating done any pro forma restriction to flesh and blood of the present utility model, any simple modification or distortion that person of an ordinary skill in the technical field has done the above specific embodiment according to technical spirit of the present utility model after having read this description, and the technology contents that may utilize above-mentioned announcement is changed or is modified to the equivalent embodiment of equivalent variations, all still belong in the scope of technical solutions of the utility model, and do not deviate from essence of the present utility model and scope.
