Mild cooling requires to be difficult to meet injection molding.
Invention content
In view of this, the utility model is in view of the existing deficiencies of the prior art, main purpose is to provide one kind can be quick
The hot nozzle structure of heating and cooling, can effectively solve the problems, such as that existing hot nozzle cannot be rapidly heated and cool down.
To achieve the above object, the utility model is using following technical solution：
A kind of hot nozzle structure for being rapidly heated and cooling down, includes ontology and heater；There is runner in the ontology,
The front end face center of ontology, which is integrally extended forward, nozzle point, which there is plastic hole, the plastic hole to be connected to runner, and ontology
Circumferential lateral surface there is an annular mounting groove, the rear end face of ontology is recessed with the annular housing for injecting coolant liquid, annular chamber
Body extends to the front end of ontology；The heater is embedded in annular mounting groove and is wrapped in this in vitro.
Preferably, muff shell is arranged with outside the ontology, the front end of nozzle point exposes to the front end face of heat preservation sheath body.
Preferably, the rear end periphery of the ontology, which extends, snap ring, and snap ring is located at the periphery of heater, the heat preservation sheath body
Rear end and snap ring snap connection fixation.
Preferably, the rear end face of the ontology is fixed with an end cap, and inlet, inlet are provided on the end cap and goes out liquid
Mouthful, which is connected to runner face, which is connected to annular housing with liquid outlet.
The utility model has clear advantage and advantageous effect compared with prior art, specifically, by above-mentioned technology
Known to scheme：
Heater can be powered on when needing to be rapidly heated by the way that having heaters and annular housing is arranged, work as needs
When carrying out fast cooling, it can be passed through coolant liquid toward annular housing, so that the sizing material temperature in runner obtains fast accurate
Control, meets the requirement of injection molding.
More clearly to illustrate the structure feature and effect of the utility model, come below in conjunction with the accompanying drawings with specific embodiment pair
The utility model is described in detail.

Specific implementation mode
It please refers to shown in Fig. 1, that show the concrete structures of the preferred embodiment of the utility model, include ontology 10
And heater 20.
There is runner 11, the front end face center of ontology 10, which is integrally extended forward, nozzle point 12, nozzle point in the ontology 10
12 have plastic hole 121, which is connected to runner 11, and the circumferential lateral surface of ontology 10 has an annular mounting groove 13；
In the present embodiment, which is aluminum alloy material, and the rear end face periphery of the ontology 10 is recessed with multiple mounting holes 14, is used
It is connected in outside installation, the plastic hole 121 is two opened each other, and the front end of runner 11 is arc-shaped structure.And
The rear end face of the ontology 10 is recessed with the annular housing 16 for injecting coolant liquid, before annular housing 16 extends to ontology 10
End.
The heater 20 is embedded in annular mounting groove 13 and is wrapped in outside ontology 10.In the present embodiment, the ontology 10
Outer to be arranged with muff shell 30, the front end of nozzle point 12 exposes to the front end face of heat preservation sheath body 30.Also, the rear end of the ontology 10
Periphery, which extends, snap ring 15, and snap ring 15 is located at the periphery of heater 20, and rear end and the buckle of snap ring 15 of the heat preservation sheath body 30 connect
Connect fixation.
And the rear end face of the ontology 10 is fixed with an end cap 40, and inlet 41, inlet are provided on the end cap 40
42 and liquid outlet 43, the inlet 41 be connected to 11 face of runner, which is connected to annular housing 16 with liquid outlet 43,
Also, inlet 42 is identical with the size of liquid outlet 43, and inlet 42 and liquid outlet 43 are with respect to inlet 41 radial symmetric setting.
The operation principle that the present embodiment is described in detail is as follows：
In use, ontology 10 is connected and fixed with outside installation, for melting sizing material into after air stream enter runner 11, heater 20 generates heat
Amount so that the sizing material in runner 11 is kept molten by, and is then melted sizing material and is projected completion injection molding action from plastic hole 121, when
When needing to control the sizing material temperature in runner 11, coolant liquid, coolant liquid are injected toward annular housing 16 by inlet 42
It is exported from liquid outlet 43, heat is taken away, realize fast cooling.
The design focal point of the utility model is：It can when needing to be rapidly heated by the way that having heaters and annular housing is arranged
Heater is powered on, when needing to carry out fast cooling, coolant liquid can be passed through toward annular housing, so that in runner
Sizing material temperature obtains the control of fast accurate, meets the requirement of injection molding.
The technical principle of the utility model is described above in association with specific embodiment.These descriptions are intended merely to explain this reality
With novel principle, and it cannot be construed to the limitation to scope of protection of the utility model in any way.Based on the explanation herein,
Those skilled in the art would not require any inventive effort the other specific implementation modes that can associate the utility model,
These modes are fallen within the scope of protection of the utility model.
