As shown in Fig. 2, for 100 principle schematic of adapted to injection system of an embodiment of the present invention.
For present embodiment by taking valve type adapted to injection system as an example, adapted to injection system 100 includes hopper 10, barrel 20 and mold system
30。
Hopper 10 is used for the injection of sizing material 50.
Barrel 20 by sizing material 50 for mixing and being delivered in mold system 30.
Mold system 30 carries out injection moulding process by the sizing material 50 received.
Here, in conjunction with Fig. 3, mold system 30 includes hot runner system 40 and mold cavity 70.
Hot runner system 40 has sizing material entrance 401 close to one end of barrel 20.
In this way, the sizing material 50 in barrel 20 is entered by sizing material entrance 401 in hot runner system 40.
In conjunction with Fig. 4 and Fig. 5, if hot runner system 40 includes flow distribution plate 41 and xeothermic nozzle component 42, if xeothermic nozzle component 42
With 41 mutual conduction of flow distribution plate.
One end of flow distribution plate 41 is connected to sizing material entrance 401, to receive sizing material 50.
Sizing material 50 is in shunting in flow distribution plate 41 and flows into each hot nozzle component 42.
Hot nozzle component 42 and 70 mutual conduction of mold cavity, after sizing material 50 extended meeting enter formed product mold cavity 70
It is interior.
In the present embodiment, in conjunction with Fig. 6 to Fig. 8, hot nozzle component 42 includes hot nozzle ontology 421, around hot nozzle ontology 421
The heating unit 422 of setting.
Hot nozzle ontology 421 is cylindrical, and 421 inside of hot nozzle ontology has the runner to circulate for sizing material 50（It does not indicate）.
Heating unit 422 is in hollow tube-shape, and heating unit 422 is used to heat to hot nozzle ontology 421 and sizing material 50 is protected
Molten condition is held, to ensure that 50 transmission process of sizing material is unobstructed.
The internal diameter of heating unit 422 is not more than the outer diameter of hot nozzle ontology 421, preferably, the internal diameter of heating unit 422 is smaller
In the outer diameter of hot nozzle ontology 421.
There is heating unit 422 fluting 4221, fluting 4221 to be passed through along the extending direction and thickness direction of heating unit 422
Heating unit 422 is worn, and side of the heating unit 422 far from hot nozzle ontology 421 is equipped with and accommodates heater strip（It does not indicate）Cabling
Slot 4222.
In other words, any cross section of heating unit 422 is C-shaped, and heating unit 422 is wrapped in semi-surrounding structure
Overlay on the outside of hot nozzle ontology 421.
Cabling channel 4222 is exposed to the surface of heating unit 422, and heater strip can be directly wound in cabling channel 4222.
Here, heating unit 422 can be made from a material that be thermally conductive, such as heating unit 422 is copper sheathing.
It should be noted that " extending direction " refers to the axial direction of heating unit 422, " thickness direction " refers to heating unit
422 radial direction, " cross section " refer in the section of radially heating unit 422.
The heating unit 422 of present embodiment has a fluting 4221, cooperation heating unit 422 shrinkage of itself, can be with
Achieve the effect that installation, convenient disassembly, and can guarantee that heating unit 422 is in close contact with hot nozzle ontology 421 to improve heat biography
Conductance can reduce technology difficulty, and heating effect is preferable in addition, accommodating heater strip using cabling channel 4222.
In the present embodiment, fluting 4221 extends along the extending direction of heating unit 422, and on extending direction, opens
The opening width of slot 4221 remains unchanged, i.e., fluting 4221 is generally rectangular shaped at this time, and but not limited to this, and fluting 4221 is alternatively
Other forms.
In conjunction with Fig. 9, at least partly cabling channel 4222 is symmetrically distributed in the both sides of fluting 4221, so, it can be achieved that heater strip
Symmetry arrangement so that hot nozzle ontology 421 is heated evenly.
Here, cabling channel 4222 is in continuously distributed, that is to say, that the initiating terminal 4222a of cabling channel 4222 can be free of discontinuities
Ground is wound in 422 surface of heating unit and reaches up to end 4222b, and the heater strip in cabling channel 4222 can be one
Whole heater strip improves heating effect in this way, can simplify technique.
The initiating terminal 4222a and end 4222b of cabling channel 4222 are close to the end of institute's heating unit 422, here, starting
It is linear type groove body to hold 4222a and end 4222b, and initiating terminal 4222a and end 4222b is mutually parallel, in this way, can be convenient for
Heater strip end（The position of i.e. corresponding initiating terminal 4222a and end 4222b）Control so that the whole cloth of hot nozzle component 42
Office is more reasonable.
In addition, initiating terminal 4222a and end 4222b connections fluting 4221.
In the present embodiment, cabling channel 4222 surround and forms multiple structures similar to " returning " font, and cabling channel
4222 bending place is arc-shaped, on the one hand, and the limited area in 422 surface of heating unit can be efficiently used, heating effect is improved,
On the other hand, cabling channel 4222 is without apparent sudden change region（There is no the region of such as right angle bending in cabling channel 4222）,
Heater strip is not easy the escape from cabling channel 4222.
An embodiment of the present invention also provides a kind of dismantling device 300 for assembling/dismantling hot nozzle component 42.
In conjunction with Figure 10 and Figure 11, dismantling device 300 includes the operation portion 301 being connected and support division 302.
Support division 302 cooperates with fluting 4221, and when acting on operation portion 301, support division 302 drives heating unit
422 expand outwardly and realize assembling/dismounting of heating unit 422 and hot nozzle ontology 421.
Specifically, dismantling device 300 is substantially L-shaped.
Support division 302 supports end 3021 and second including at least first and supports end 3022.
First, which supports end 3021, includes two first supporting surface 3021a, 3021b being oppositely arranged, and second supports end 3022
Second supporting surface 3022a, 3022b being oppositely arranged including two.
The first distance between two first supporting surfaces 3021a, 3021b is less than two second supporting surfaces 3022a, 3022b
Between second distance, and opening width when the first distance is substantially equal to 4221 original state of fluting, in this way, supporting when first
End 3021 with fluting 4221 cooperate when, first support end 3021 and heating unit 422 between there is no active force, heating unit
422 keep original state, when rotating operating unit 301, which makes second to support end 3022, to cooperate with fluting 4221, second
It supports 3022 effect fluting 4221 of end to deform to both sides and heating unit 422 is driven to expand outwardly, at this point it is possible to facilitate heating single
The attaching/detaching of member 422.
It should be understood that support division 302 can be the cylindrical structure of original state, by cutting support division 302
Opposite sides can form two first supporting surfaces 3021a, 3021b, and uncut opposite sides just forms two second
Supporting surface 3022a, but not limited to this.
It should be appreciated that although this specification is described in terms of embodiments, but not each embodiment only includes one
A independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should will say
As a whole, the technical solution in each embodiment may also be suitably combined to form those skilled in the art can for bright book
With the other embodiment of understanding.
The series of detailed descriptions listed above only for the present invention feasible embodiment specifically
Bright, they are all without departing from equivalent implementations made by technical spirit of the present invention not to limit the scope of the invention
Or change should all be included in the protection scope of the present invention.
