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.
