Abstract
The utility model discloses an orientated plastics pipe equipment, including the bush, set up at the plug at bush center, set up at the sizing cover in bush the place ahead and be used for carrying out refrigerated cooling device to the tubular product outer wall, follow the axle center direction of plug is formed with the passageway that link up around one, an intake pipe is inserted in the passageway, and the front end of intake pipe extends the guider that a compressed air who carries the intake pipe guided is installed to pipe inner wall at the front end of intake pipe in the entrance of sizing cover. Guider is a double -deck disc, forms the space between two discs. The longitudinal section of double -deck disc is the V -arrangement of opening towards sizing cover front end. The rear end and an air compressor machine of intake pipe are connected. Through the forced air cooling, the phenomenon of hanging down that melts of the tubular product that has significantly reduced makes the homogenizing wall thickness of tubular product, has effectively practiced thrift the raw materials, has reduced the cost of tubular product.
Description
Technical field
This utility model relates to plastic pipe and manufactures field, particularly relates to a kind of plastic tube forming device.
Background technology
When producing heavy caliber, thick-walled plastic tubing, it is up to 200 degree owing to entering the temperature of the tubing of calibration sleeve, so,
The actually molten in thickness of tubing now, the outer surface of tubing is cooled down by Water spray, so that its curing molding.But by
In plastics, such as polyethylene etc. is the non-conductor of heat, its internal temperature can not be distributed by heat exchange pattern in time and
Curing molding, therefore, under the effect of self gravitation, the material on tubing top can flow downward, and is commonly called as sag, causes tubing four
The wall unevenness in week is even.
Existing solution is mainly adjusted from technique, allows mouth die and plug between the upper and lower when installation mold
Gap is inconsistent, makes upper gap be more than following gap, so makes the top wall thickness of the tubing of extrusion be more than bottom wall thickness, rear
In continuous cooling procedure, under the effect of sag, the wall thickness of top and the bottom is made to reach unanimity.
The shortcoming of said method is that sag is still serious, and material cools and solidifies uncontrollable wherein, easily causes both sides
The thinnest thick situation, the problem that still cannot effectively solve wall unevenness.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of plastic tube forming device, it is possible to avoid sag to cause
Tube wall inequality problem.
To this end, the technical solution of the utility model is as follows:
A kind of plastic tube forming device, the plug including mouth die, being arranged on mouth die center, is arranged on determining of mouth die front
Footpath is overlapped and for the chiller cooling down outer pipe wall, and the axis direction along described plug is the most through before and after being formed with one
Passage, an air inlet pipe is inserted in described passage, and the front end of air inlet pipe extends the porch of described calibration sleeve, before air inlet pipe
End is provided with the guider compressed air that air inlet pipe carries guided to pipe material inner wall.
Described guider is pair of lamina disk, forms space between two disks.The longitudinal cross-section of described double-deck disk
For opening towards the V-arrangement of calibration sleeve front end.The rear end of described air inlet pipe is connected with an air compressor machine.
In this utility model, by air compressor machine, compressed air it is blown into disk and diffuses to tubing surrounding inwall, by cold
Wind cools down rapidly by pipe material inner wall, forms one layer of hard cured layer, can be greatly reduced the sag phenomenon of tubing, it is achieved tube wall thickness
Uniform.
Effect of the present utility model
By air-cooled, greatly reduce the sag phenomenon of tubing, make the uniform wall thickness of tubing, be effectively saved raw material, fall
The low cost of tubing.
Accompanying drawing explanation
Fig. 1 is the structural representation of plastic tube forming device of the present utility model；
Fig. 2 is the cross-sectional view of calibration sleeve porch in Fig. 1.
Wherein:
1, plug 2, mouth die 3, calibration sleeve 4, air compressor machine 5, air inlet pipe
6, disk 7, plastic pipe 8, fused materials
Detailed description of the invention
Below in conjunction with the accompanying drawings the structure of plastic tube forming device of the present utility model is described in detail.
Seeing Fig. 1 and Fig. 2, plastic tube forming device of the present utility model includes: mouth die 2, be arranged on mouth die 2 center
Plug 1, it is arranged on the calibration sleeve 3 in mouth die 2 front and for chiller that the outer wall of plastic pipe 7 is cooled down (in figure
Do not show).
Axis direction along plug 1 is formed with passage through before and after, and air inlet pipe 5 is inserted in this passage, and air inlet pipe 5
Front end extend the porch of calibration sleeve 3.One compressed air air inlet pipe carried is installed to tubing in the front end of air inlet pipe 5
The guider of wall guided in 7.This guider can be a double-deck disk 6, is formed with space between two disks.
Preferably, the longitudinal cross-section of described double-deck disk 6 is the opening V-arrangement towards calibration sleeve front end, i.e. compressed air
Through air inlet pipe 5 along the space forward upward blowout between two disks, the flow resistance of air can be reduced.
The rear end of air inlet pipe 5 is connected with air compressor machine 4, is used for providing compressed air.
Below the process utilizing this device moulding plastics tubing is illustrated.
Resin particle, such as polyvinyl resin, after pipe extruder heating (about 200 degree), becomes the fused mass of thickness
Material 8.After fused materials 8 is by the space between mouth die 2 and plug 1, it is shaped into cylindrical shape and enters in calibration sleeve 3.Here, it is molten
Melt material 8 to be evacuated, be close on the inner surface of calibration sleeve 3.Meanwhile, its outer surface is cooled and solidified after Water spray, is formed
Cylindric plastic pipe 7.
Meanwhile, air compressor machine, by after air compression cooling, enters between two disks of double-deck disk 6, circle by air inlet pipe 5
Dish is positioned at inside tubing, and compressed air blows to the surrounding inwall of tubing, makes the pipe material inner wall of heat cool down rapidly, solidify, forms one
The cured layer that layer is hard, thus prevent material flowing under gravity.
