Between relevant description.
In the present embodiment, in conjunction with Fig. 1 and Fig. 2, hot nozzle structure 42 is including hot nozzle ontology 421 and around hot nozzle ontology
The pipe sleeve 422 of 421 settings.
Hot nozzle ontology 421 is cylindrical, and 421 inside of hot nozzle ontology has the runner to circulate for sizing material（It does not indicate）.
Pipe sleeve 422 is in hollow tube-shape, and pipe sleeve 422 is used to heat to hot nozzle ontology 421 and so that sizing material is kept molten by,
To ensure that sizing material transmission process is unobstructed.
Pipe sleeve 422 can be made from a material that be thermally conductive, for example, pipe sleeve 422 is copper pipe.
The outer surface of hot nozzle structure 42 is equipped with the cabling channel 423 for accommodating wire body 424.
In the present embodiment, cabling channel 423 is located at side of the pipe sleeve 422 far from hot nozzle ontology 421, but not as
Limit, for example, hot nozzle structure 42 is integral（I.e. hot nozzle ontology 421 is integrated with pipe sleeve 422）, cabling channel 423 is located at
The outer surface of hot nozzle structure 42.
There is cabling channel 423 limiting section 4231 to be detached from cabling channel 423 to limit wire body 424.
It should be noted that " limitation wire body 424 is detached from cabling channel 423 " can refer to being extracted on direction in wire body 424, limit
Position portion 4231 limits wire body 424 and is detached from cabling channel 423, and either, wire body 424 contacts with each other with limiting section 4231 and avoids wire body
424 are detached from cabling channel 423.
Here, by taking wire body 424 is heating wire 424a as an example, heating wire 424a is fitted close and will not take off with cabling channel 423
From cabling channel 423, heating effect can effectively improve.
It should be understood that wire body 424 or other structures.
In the present embodiment, limiting section 4231 is at least partly madial wall of cabling channel 423.
Specifically, in conjunction with Fig. 3 and Fig. 4, on the direction of 423 extending direction of cabling channel, the section of cabling channel 423
Trapezoidal S, the bottom S1 of trapezoidal S and two waist edges（S2、S3）Enclose the madial wall for setting and forming cabling channel 423.
That is, at this point, the upper bottom edge S4 of trapezoidal S corresponds to the opening of cabling channel 423, bottom S1 corresponds to cabling channel
423 bottom, on 423 depth direction of cabling channel, the width of cabling channel 423 gradually increases.
Two waist edges（S2、S3）Angle between the S1 of bottom is acute angle, and limiting section 4231 is two waist edges
（S2、S3）.
Preferably, trapezoidal S is isosceles trapezoid.
Two waist edges（S2、S3）Can be arc transition between the S1 of bottom.
It should be understood that when heating wire 424a is limited in cabling channel 423, two waist edges（S2、S3）It contacts and applies
In mono- directed force Fs of heating wire 424a, and the depth direction that the directions component F1 of directed force F are cabling channel 423（That is heating wire
424a extracts direction）, at this point, component F1, which can limit heating wire 424a, is detached from cabling channel 423.
In addition, cabling channel 423 can only subregion section be it is trapezoidal.
In the present embodiment, heating wire 424a is made of deformable material, and heating wire 424a has first state（Initially
State）And second state（Deformation state）, here, by taking the cross section of heating wire 424a original states is round as an example.
In conjunction with Fig. 3, when heating wire 424a is in first state, heating wire 424a is not deformed, and heating wire 424a is protruded out
Cabling channel 423, at this point, limiting section 4231（That is two waist edges）Heating wire 424a is not forced in, and but not limited to this.
In conjunction with Fig. 4, when heating wire 424a is squeezed deformation and is in the second state, 4231 contact heating silk of limiting section
424a。
Here, substantially it is that more heating wire 424a are pressed into cabling when heating wire 424a is in the second state
Inside slot 423, at this point, heating wire 424a and the contact area of cabling channel 423 become larger, heating effect is improved.
It should be understood that heating wire 424a can be made of the not strong material of elasticity, at this point, when heating wire 424a is in the
When two-state, heating wire 424a is not easy to be detached from cabling channel 423 because of itself rebound effect.
Certainly, on the direction of 423 extending direction of cabling channel, the section of cabling channel 423 also can be in other shapes,
For example, the rectangular cross-section of cabling channel 423, at this point, when heating wire 424a deformations make more heating wire 424a enter to walk
When wire casing 423, the contact surface of heating wire 424a and 423 madial wall of cabling channel, which connects, to become larger, and remains able to improve heating effect.
In the present embodiment, in conjunction with Fig. 5, the outer surface of hot nozzle structure 42 is additionally provided with the temp.-sensing wire for accommodating temp.-sensing wire 425
Slot 426.
Here, on the direction of 423 extending direction of cabling channel, the rectangular in cross-section of temperature-sensitive wire casing 426, temp.-sensing wire
425 section is rounded.
Temp.-sensing wire 425 is pressed into temperature-sensitive wire casing 426, and temp.-sensing wire 425 is indeformable, in this way, the temp.-sensing wire that can adequately protect
425 are not damaged.
The depth of temperature-sensitive wire casing 426 can be more than the diameter of temp.-sensing wire 425, and but not limited to this.
In the present embodiment, heating wire 424a and temp.-sensing wire 425 are separately positioned on cabling channel 423 and temperature-sensitive wire casing 426
In so that the whole occupied space of hot nozzle structure 42 is smaller, and frame is opened to effectively reduce system.
In the present embodiment, in conjunction with Fig. 6, the leading-out terminal of heating wire 424a and temp.-sensing wire 425 is located at the same of pipe sleeve 422
At end, and three leading-out terminal laid out in parallel, the control of leading-out terminal can be convenient for so that the integral layout more adduction of hot nozzle structure 42
Reason.
In the present embodiment, join Fig. 7, side of the heating unit pipe sleeve 422 far from hot nozzle ontology 421 is additionally provided with force section
428, outer member drives heating unit pipe sleeve 422 to be detached from hot nozzle ontology 421 by force section.
Specifically, force section 428 is around the threaded portion 428 of 422 outer surface setting of heating unit pipe sleeve, it can be by outer
The cooperation of portion's element and threaded portion 428 drives 422 relatively hot nozzle ontology 421 of heating unit pipe sleeve along the radial direction of hot nozzle ontology 421
And/or be axially moved, in order to the attaching/detaching of heating unit pipe sleeve 422.
The structure of force section 428 is not limited with threaded portion, can be depending on actual conditions.
In the present embodiment, pipe sleeve 422 has through hole 427, and hot nozzle structure 42 further includes across through hole 427 and supporting
Hold the fixing piece of hot nozzle ontology 421（It does not indicate）.
Here, through hole 427 is threaded hole 427, and fixing piece is grub screw, when grub screw is supported by threaded hole 427
When being held in the outer surface of hot nozzle ontology 421, pipe sleeve 422 can not be rotated relative to hot nozzle ontology 421, with realize hot nozzle ontology 421 with
Pipe sleeve 422 is relatively fixed.
