Description
Technical field
It the utility model is related to plastic pipe manufacturing field, more particularly to a kind of large diameter pipeline production and processing instrument.
Background technology
When producing heavy caliber, thick-walled plastic tubing, because the melting material temperature of extrusion is high, material cooling velocity is slow,
Cause material to be still in sticky molten condition after the extrusion, the outer wall of tubing and air contact and cool down or sprayed with cold water cold
But, until the whole tube wall of tubing cools and solidifies shaping completely, but because the poor thermal conductivity of plastics, the heat of pipe material inner wall do not have
Method disperses in time, and the cool time for causing to shape required is grown, and the material for not cooling and solidifying shaping completely still has necessarily
Mobility is sent out, therefore, in the presence of self gravitation, the material on tubing top flows downward, and sag phenomenon occurs, causes tubing
Wall unevenness, product size is unqualified, has also had a strong impact on the overall performance of tubing, simultaneously because cooling and solidifying shaping efficiency
It is low, also constrain tubing production efficiency.
In the prior art, some is hung down the material of the trade mark using special eutectic, can effectively prevent sag phenomenon, but due to
This special material price is high, the production cost greatly increased；Also have by zonal control die temperature, it is serious for sag
Position, reduce chilling temperature, although the generation of the sag phenomenon of material can be prevented to a certain extent, material due to temperature not
, certain stress be present, cause performance to change.
Utility model content
The utility model is to overcome at least one defect described in above-mentioned prior art, there is provided a kind of large diameter pipeline production
Machining tool, it can effectively accelerate pipe material inner wall cooling velocity, prevent the generation of sag phenomenon, caused by avoiding sag
Tube wall inequality problem.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of large diameter pipeline production is provided
Machining tool, including mouth mold, the core rod, the material channel being made up of mouth mold and core rod that are arranged on mouth mold center, in the core rod
The gas passage penetrated before and after one is set, in the end set circle cooling vane of gas passage.
Further, a gas pipeline is installed in the gas passage.It is circular cold for cooling air is delivered to
But in vane.
Further, one end of the gas pipeline is connected with circular cooling vane, and the other end is connected with refrigeration compressor.
Described circular cooling vane can adjust certain region openings degree to change the flow of local air according to tubing thickness requirement,
Reach cooling effect, improve the uniformity of tubing thickness.
Compared with prior art, the beneficial effects of the utility model are：By setting up refrigeration air compressor machine, being set in core rod
The gas pipeline and the one circular cooling vane of setting at die orifice penetrated before and after one, can by this new mouth mold device
Change cooling wind direction and air quantity according to specific needs, realize the cooling and solidifying of pipe material inner wall, the sag for greatly reducing tubing shows
As the raw materials for production effectively saved, reducing production cost, improving production efficiency.
Brief description of the drawings
Fig. 1 is a kind of structural representation of large diameter pipeline production and processing instrument of the utility model.
Fig. 2 is A-A directional profiles structural representation in the utility model accompanying drawing 1.
In accompanying drawing：1 mouth mold, 2 core rods, 3 material channels, 4 gas passages, 5 circular cooling vanes, 6 refrigeration compressors, 7. is molten
Melt material, 8. arrows, represent cooling wind trend.
Embodiment
Accompanying drawing being given for example only property explanation, it is impossible to be interpreted as the limitation to this patent；It is attached in order to more preferably illustrate the present embodiment
Scheme some parts to have omission, zoom in or out, do not represent the size of actual product；To those skilled in the art,
Some known features and its explanation may be omitted and will be understood by accompanying drawing.Being given for example only property of position relationship described in accompanying drawing
Explanation, it is impossible to be interpreted as the limitation to this patent.
As shown in figure 1, a kind of large diameter pipeline production and processing instrument, including mouth mold 1, the core rod for being arranged on the center of mouth mold 1
2nd, the material channel 3 being made up of mouth mold 1 and core rod 2, the gas passage 4 penetrated before and after one is set in the core rod 2, in gas
The end set circle cooling vane 5 of body passage 4.
Specifically, a gas pipeline is installed in the passage 4.For cooling air is delivered into circular cooling vane
In 5.
Specifically, one end of the gas pipeline is connected with circular cooling vane 5, and the other end is connected with refrigeration compressor 6.
Described circular cooling vane 5 can adjust certain region openings degree to change the stream of local air according to tubing thickness requirement
Amount, reach cooling effect, improve the uniformity of tubing thickness.
When the raw material of production plastic pipe, such as high density polyethylene (HDPE), polyvinyl resin, it is heated to form in extruder head molten
Melt material 7, fused materials 7 are extruded into cooling and shaping in calibration sleeve by described material channel, after vacuumizing, melted
To melt material 7 and be close to calibration sleeve, outer surface is cooled and solidified by shower water, meanwhile, refrigeration compressor 6 is opened, cooling air leads to
To cross gas pipeline and be passed through circular cooling vane 5, circular cooling vane 5 judges air output and wind direction according to setting program, so as to
Purposeful cooling pipe material inner wall, makes pipe material inner wall cool down rapidly, solidify, forms cured layer, effectively prevent the generation of sag phenomenon.
Obviously, above-described embodiment of the present utility model is only intended to clearly illustrate the utility model example, and
It is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, in described above
