Description
Technical field
The present invention relates to a kind of three color double injection machine extrusion dies.
Background technology
The demand of existing electric wire is more and more, however present three colors double hyer insulation is also the development of present electric wire
Direction.
Double-layer coextrusion insulated mechanical performance and electric property is better than single layer dielectrics, however double-layer coextrusion insulated Huang now
Green other dichromatic cable speeds of production of double-colored grade are slower, need to be insulating exruded at twice, and once, external insulation once, can go out interior insulation
Existing following point.
1st, insulation squeezes out at twice, and primary insulation squeezes out once, and outer layer insulation squeezes out one layer, greatly reduces the life of insulation
Produce efficiency；
2nd, insulation squeezes out at twice, adds mechanical damage number of the interior insulation in carrying；
3rd, interior insulation can increase interior insulation surface impurity and dirt dimly after squeezing out when insulation squeezes out at twice, so that
External insulation bonds insufficient；
4th, head cleaning time is more, and cable interior insulation cleans once after squeezing out, and external insulation cleans once after squeezing out, significantly
The stability of head is compromised, the efficiency of the production so reduced and improves production cost.
The content of the invention
The present invention provides a kind of double-deck note of three colors that can complete the double-deck extrusion of three color of cable simultaneously to solve the above-mentioned problems
Molding machine.
The technical scheme is that：
A kind of three color double injection machine extrusion dies, which is characterized in that including interior mold and outer mold, the interior mold exterior
Equipped with casing, external shunt device is equipped in casing, current divider in external shunt device inner sleeve, the casing is equipped with and is respectively equipped with main feed
Mouthful, the first auxiliary feed inlet and the second auxiliary feed inlet, current divider in the main feed mouth connection, the first auxiliary feed inlet and second it is auxiliary into
Material mouth connects external shunt device, and the external shunt device and interior current divider are connected with outer mold.
Further, the external shunt device generally one end is to the tapered bullet type of the other end, the table of the external shunt device
Face is equipped with diversion channel, and the diversion channel includes the transverse groove of the first auxiliary feed inlet of connection, vertical block is equipped in the transverse groove,
The connecting pin of the first auxiliary feed inlet is equipped with blow tank, and blow tank one side is equipped with opening I, and the height of groove is omited where opening I
Higher than blow tank, the blow tank connects hopper I, and splicing groove I is connected with opening I hopper II, hopper II connection blow tanks, institute
It stating side walls of the hopper II close to outer mold one side and is slightly below the other end, the hopper I is equipped with hopper III close to outer mold one side,
Hopper III is equipped with opening, the second auxiliary feed inlet of hopper III connections close to outer mold one side.
Advantageous effect：
It solves the problems, such as that three color double hyer insulations squeeze out at twice to be changed to once squeeze out, adds production effect during production
Rate；The extraneous collision and mechanical damage that primary insulation is subject to when avoiding production twice；Avoid twice production when interior insulation because
There is phenomena such as dirt in primary insulation caused by the problems such as storage；Reduce the cleaning time of cable head, so as to add machine
Head the problem of property.
