Detailed description of the invention
Understandable for enabling above-mentioned purpose of the present utility model, feature and advantage to become apparent from, under
Face combines accompanying drawing and is described in detail detailed description of the invention of the present utility model.
Refer to Fig. 1, this utility model provides a kind of injection molded tube insulation construction, this guarantor
Temperature encapsulated by structures at injection molded tube 1 outer layer, injection molded tube 1 connect batch charger (not shown) and
Injecting systems (not shown).
Usually, batch charger is funnel-form, can put in batch charger by plastic raw materials by hand, relatively
Goodly, batch charger can arrange reducing mechanism, plastic raw materials is ground into powder, then
Enter in injection molded tube 1.
Refer to Fig. 2, outside injection molded tube 1, along direction from the inside to the outside, be wrapped in successively
Heater, heat ray filter and shell 03.
In the present embodiment, heater is heating rod 01, and heat ray filter is heat insulation foam 02,
The lamella that shell 03 is insulation material or heat-barrier material is made, and use steady pin 031
One end of lamella is connected with the other end, to form the outer protective jacket of similar closed figure.
Refer to Fig. 1, in order to avoid plastic raw materials enters injection molded tube 1 unexpected from batch charger
Contact too high temperature and carbonization or vaporization occur, therefore insulation construction is divided into three sections, from
Batch charger is followed successively by first module insulation construction 2, second unit to the direction that injecting systems extends
Insulation construction 3 and the 3rd unit insulation construction 4.
Each unit insulation construction is similar, is all to wrap up heating successively at injection molded tube 1 outer layer
Rod 01, heat insulation foam 02 and shell 03, the S type that is shaped as of heating rod 01, and note of fitting
Mould the tubular surface of pipeline 1, for increasing the heating surface area of injection molded tube 1.
Owing to the operating temperature requiring the heating rod 01 of each insulation construction is different, therefore exist
When normally working, the power of the heating rod 01 of each unit insulation construction is different.
Usually, the operating temperature of first module insulation construction 2 is more than second unit insulation construction
The operating temperature of 3, the operating temperature of second unit insulation construction 3 is more than the 3rd unit insulation knot
The operating temperature of structure 4, arranging the operating temperature of first module insulation construction 2, to be slightly below plastics former
The fusing point of material, arranges the operating temperature of second unit insulation construction 3 for equal to or slightly greater than to mould
The fusing point of material raw material, arranges the operating temperature of the 3rd unit insulation construction 4 more than plastic raw materials
Fusing point but less than the boiling point of plastic raw materials.Usually, the temperature difference of three 10 DEG C～20 DEG C,
If but the plastics fusing point for being molded differs greatly with boiling point, then the temperature of three unit insulation constructions
Degree difference scope is bigger.
According to above-mentioned setting, plastic raw materials, after batch charger enters injection molded tube 1, first passes around
First module insulation construction 2, now due to the heating rod 01 of first module insulation construction 2
Operating temperature is slightly below the fusing point of plastic raw materials, the most now first module insulation construction 2 sections
Plastic raw materials not yet melt, only preheat, when it flow to second unit insulation construction 3
Duan Shi, owing to the operating temperature of now second unit insulation construction 3 is equal to or slightly greater than plastics
The fusing point of raw material, then plastic raw materials fusing forms liquid plastics, when this liquid plastics flow to work
When making the 3rd unit insulation construction 4 sections that temperature is more than plastic raw materials, owing to temperature is higher, should
It is relatively abundant that liquid plastics melts, and therefore the mobility of liquid is preferable, it is to avoid it is flowing to injection
During the nozzle of system, result in blockage.
Use the device that this utility model provides, heating rod 01 temperature of injection molded tube 1 outer wrapping
Degree gradually rises, and arranging temperature near one end of batch charger at injection molded tube 1, to be slightly less than plastics former
Material fusing point, arranges a little higher than plastic raw materials of temperature at injection molded tube 1 near one end of injecting systems
Fusing point, after such plastic raw materials enters injection molded tube 1, it is possible to gradually melt, it is to avoid it is dashed forward
So enter the temperature section higher than plastic raw materials fusing point and carbonization or vaporization occur, improve plastics former
The utilization rate of material, at one layer of heat insulation foam 02 of heater outer wrapping, it is to avoid heating rod 01 is by warm
Amount is delivered in air, decreases the loss of heat, improves the temperature utilization rate of heater.
Obviously, those skilled in the art utility model can be carried out various change and modification and
Without departing from spirit and scope of the present utility model.If these amendments of the present utility model and modification belong to
Within the scope of this utility model claim and equivalent technologies thereof, then this utility model is also anticipated
Figure is changed and including modification include these.
