Description

Head of extruding machine mould

Technical field

A kind of cable processing technique field is the utility model is related to, more particularly to a kind of head of extruding machine mould.

Background technology

At present, the Chinese patent that Authorization Notice No. is CN205185263U discloses one kind and exempts to adjust extrusion head, including enters Mould before line, mould is provided centrally with and waited to mould the first through hole that core coordinates before inlet wire, and mould outlet tail end is taper before inlet wire, is entered Mould outlet tail end is provided with the fixation rear mold matched with its external surface shape before line, and fixed rear mold side wall is uniformly distributed and symmetrically set It is equipped with and multiple enters to mould mouth；Fixed rear mold inwall is additionally provided with and enters to mould mouth to the guiding gutter applied to water conservancy diversion；Fixed rear mold is set There is the second through hole coordinated with first through hole, the second through hole mould one end before inlet wire is provided with even pressure ring；Mould, water conservancy diversion before inlet wire Groove is provided with high temperature resistant lubricant coating with even pressure ring surface；Fixed rear mold is set, and guiding gutter is arranged in fixed rear mold, It is high without debugging, production efficiency when being produced；Guiding gutter is arranged to corrugated, sets even pressure ring, air pressure tank, and in inlet wire Preceding mould, guiding gutter and even pressure ring surface are provided with high temperature resistant lubricant coating, ensure that cable quality.

But above-mentioned extrusion head is in use, due to the effect of friction, at extrusion head especially on inwall Temperature gradually rises, and the cored wire of cable is with injection rubber in the different situation of temperature, and adhesion etc. is also not quite similar, therefore There may be cable quality of the wire in Various Seasonal, varying environment output to differ.

Utility model content

The purpose of this utility model is to provide the extrusion head that a kind of temperature is constant, output product quality is stable.

Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of extrusion head, bag Include mould and fixed rear mold before inlet wire, there is entrance hole in mould before the inlet wire, is formed before the inlet wire between mould and fixation rear mold Enter and mould chamber, the wire hole with entrance hole face is provided with the fixed rear mold, the wire hole turns on entering to mould chamber, described solid Determine to have in rear mold and some symmetrically arranged enter to mould mouth, it is characterised in that：There is cooling chamber, the cooling before the inlet wire on mould Chamber is twist centered around on the outside of entrance hole, and the cooling chamber is in double-spiral structure, and the cooling chamber includes water inlet and water outlet Mouthful, the water inlet is located at the top and bottom of mould before inlet wire with delivery port respectively, and the water inlet is with delivery port positioned at same Horizontal level.

By using above-mentioned technical proposal, it is passed through coolant using cooling chamber and mould before inlet wire is cooled down, avoid cored wire The frictional heat in entrance hole, constantly accumulate heat and form high temperature, influence the performance of cable rubber materials added, and conductor temperature Too high, when discharge opening is with entering to mould chamber connected position coating cable rubber materials, larger expansion occurs for cable rubber materials, in follow-up work Cheng Zhong, temperature decline, and sizing material shrinks, and may cause the stripping with wire, and cooling chamber cools down to entrance hole, reduce cored wire temperature Degree, ensures that the cable performance of output is uniform；The double-spiral structure area of dissipation of cooling chamber is big, and preferably entrance hole can be carried out Cooling, water inlet and delivery port are arranged on cooling chamber the same side, coolant is threadingly advanced screw backout again, in whole cooling chamber Temperature is more uniform, more uniform to the cooling at entrance hole.

The utility model is further arranged to：Feeding ring is provided with the wire hole, the inwall of the feeding ring is set For frosted Rough Horizontal Plane.

By using above-mentioned technical proposal, the inwall of feeding ring is Rough Horizontal Plane, due to the viscosity of cable sizing material, can be made Obtain and be covered with cable sizing material on the inside of feeding ring, so as in cored wire motion process, uniformly coat a layer sizing, ensure output cable Can uniformly it extrude.

The utility model is further arranged to：It is described to enter to mould the inwall of chamber, feeding ring and wire hole and be coated with high temperature resistant Coating.

By using above-mentioned technical proposal, the setting of high temperature resistant figure layer avoids the residual solidification of cable sizing material, ensures glue Expect the clean and tidy of the environment of feeding, reduce the loss of material, while also can guarantee that the surface of output cable will not produce defect.

The utility model is further arranged to：Described to enter to mould mouth and be connected with storage tank, the storage tank is set after fixation The both sides of mould, the storage tank are externally connected with gas boosting pump.

By using above-mentioned technical proposal, both sides set storage tank to be fed respectively, and feed location is more uniform, can be with Preferably at conveying sizing material to cored wire, the pressure in storage tank can be adjusted for gas boosting pump, so as to control the speed of feeding Degree so that what sizing material can be uniform and stable is transported on cored wire.

The utility model is further arranged to：Pressure gauge is connected with the storage tank.

By using above-mentioned technical proposal, pressure gauge facilitates operating personnel to carry out pressure monitoring, so as to be supplemented in good time The operation of sizing material or intensified pressure, it ensure that caused cable quality keeps more uniform state.

The utility model is further arranged to：The fixed rear mold is provided with spiral outlet cooling outside wire hole Hole, the outlet Cooling Holes include the outlet of the water inlet and face feeding ring positioned at wire hole exit end.

By using above-mentioned technical proposal, outlet Cooling Holes carry out the circulation of coolant against the direction of wire hole, so as to Temperature forms the gradient gradually reduced, facilitates sizing material to be cooled into stable structure, improves output cable quality.
