Description
Technical field：
The utility model is related to power cable technical field, relates in particular to a kind of cable insulation jacket and partly pressurize extrusion
Mold.
Background technology：
Cable is typically by several or the cable of similar rope that several groups of conducting wires (every group at least two) are twisted, every group
Mutually insulated between conducting wire, and be often twisted into around a center, entire outside is surrounded by the cable jacket of high-insulation.PVC because
Its material has height slight, and wearability, material itself has good anti-flammability, it is often more important that is easily worked as cable insulation
Sheath is widely used, however plasticizer in PVC, may ooze out or gasification can interfere biological endocrine (to influence reproduction machine
Can), it can partly increase carcinogenic risk；PVC burnings will produce carcinogenic dioxin and pollute air, be decomposed in PVC process
Stench is generated, this gas is harmful, and higher and higher recently as global environmentally friendly cry, people also increasingly pay attention to ring
Guarantor and own health, five poisonous creatures: scorpion, viper, centipede, house lizard, toad environment-friendly materials such as TPE, TPU, XL-PE etc. start to replace PVC, gradually applied to cable insulation jacket.
Since material substrates such as TPE, TPU, XL-PE itself do not have anti-flammability, need to increase a large amount of fire retardant such as Mg
(OH) 2, Al (OH) 3, phosphate is fire-retardant to meet material, these fire retardants and substrate compatibility are poor, cable insulation jacket
The external eyes of extrusion external mold easily there is accumulated slag (accumulated slag：The plastic cement material being deposited in when cable insulation jacket extrusion at external mold gum outlet
Material), accumulated slag easily abrades cable surface, can adhere to cable insulation jacket surface when the accumulation of outer die orifice is a certain amount of, form protrusion,
It causes this section of cable to scrap, seriously affects production efficiency, while needing to increase and manually finding out raised position.
One mold packaged will make the quality of product and production efficiency be greatly improved, and existing mold is according to mold
Structure can be divided into crowded tubular type and squash type, and half squash type, it is 40 degree to squeeze tubular type and half plsitive mold cone angle, squash type cone angle
It it is 60 degree, plsitive mold is that plastic cement is coated on progress in head, and plastic cement shapes in the state of being in compression, and this mold is usual
For conductor more close occasion Nian Jie with insulating layer；Tubular molding tool is effect elder generation of the plastic cement in die sleeve exit due to mold
Form tubulose, plastic cement is adsorbed on cable core by the effect of redrawing, be commonly used in sheath plastic cement and cable core bonding it is not tight in the case of, line
In order to which sheath and cable core are easily peeled off in the production of cable sheath, frequently with tubular molding tool.Existing tubular molding tool such as Fig. 1 institutes
Show, including external mold 1 and internal model 2, external mold 1 is provided with 60 ° of taper holes 11 and circular hole 12, and one end outer surface of internal model 2 is and 11 phase of taper hole
Corresponding 60 ° of cone angles 21, the length of taper hole 11 are 2~4cm, are provided with taper glue feeding opening 22 and plastic hole 23 in internal model 2, taper into
The angle in glue hole 22 is identical as the angle of cone angle 21, and taper glue feeding opening 22 interlinks with plastic hole 23, and the cone angle 21 of internal model 2 inserts
In the taper hole 11 of external mold 1, plastic hole 23 interlinks and concentric with circular hole 12.Due to the signature of the external mold 1 of this tubular molding tool
It is that plane is more also easy to produce when being molded insulating sheath extrusion from the circular hole 12 of external mold 1 in the extrusion end face of external mold 1 to go out end face
Accumulated slag, accumulated slag are easily adhered to cable surface and form protrusion, excessive using half pressurization or full pressurization sheath and cable core adhesion strength, do not allow
Yi Kaipi, current half pressurization and full pressurizing mold easily generate accumulated slag, cause strong influence to cable quality, greatly increase
Production cost.
Utility model content：
The purpose of this utility model is to provide a kind of preventing deposit cable insulation jacket and partly pressurizes extrusion die, it passes through change
The structure of extrusion die makes the binding force between extrusion plastic cement and cable core reduce, while greatly reducing the product of external mold extrusion end face
Slag reduces the probability that accumulated slag adheres to insulating sheath, improves the quality of cable, reduces cable and scraps.
The technical scheme adopted by the utility model is that：
A kind of preventing deposit cable insulation jacket partly pressurizes extrusion die, including external mold and internal model, external mold are provided with taper hole and circle
Hole, one end outer surface of internal model are cone angle corresponding with taper hole, are provided with taper glue feeding opening and plastic hole in internal model, and taper is into glue
The angle in hole is identical as the angle of cone angle, and taper glue feeding opening interlinks with plastic hole, and the cone angle of internal model is inserted into the taper hole of external mold
Interior, plastic hole interlinks and concentric with circular hole, it is characterized in that：The angle of taper hole is 30~35 °, and the angle of cone angle is 28~32 °,
The angle of taper hole is 1 °~3 ° bigger than the angle of cone angle, and the length of taper hole is 3~8cm, and external mold depanning end is the conical surface, the circular hole of external mold
Angle between depanning end cone face is 45 °~65 °.
Further, the angle of the taper hole is 32 °, and the angle of cone angle is 30 °.
Further, the length of the taper hole is 8cm.
Further, the angle between the circular hole of the external mold and depanning end cone face is 60 °.
Due to integrally reducing external mold taper hole and internal model cone angle, the cone angle of internal model taper glue feeding opening, which synchronizes, to be reduced, and sizing material is worked as
When being extruded outward from internal model taper glue feeding opening, the propulsive force of sizing material makes internal model generate pressure to external mold, and external mold generates internal model
Reaction force, external mold taper hole and internal model angle of taper are smaller, and active force is smaller with reaction force, so that plastic material is exhausted
Binding force between edge sheath and cable core is smaller.The utility model external mold taper hole both can guarantee insulating sheath with internal model angle of taper
Binding force between cable core, prevents cable core to be extracted easily, and so that skin is opened between insulating sheath and cable core to be easy.External mold is bored
There are differential seat angles between hole and internal model cone angle, can be formed and be squeezed to plastic material, and increasing material mixing makes material structure closely go out
It is not easy to form accumulated slag under rubbing action when die orifice, while setting external mold depanning end to the conical surface, external mold depanning circular hole and depanning
It is taper wedge angle between end cone face, when insulating sheath is extruded from external mold depanning circular hole, a small amount of accumulated slag can rest on conical points
It on angle, will not be adhered directly on insulating sheath, greatly reduce the frequency that accumulated slag is directly attached on wire rod, ensure the matter of cable
Amount, to be significantly reduced production cost.
