Description
Technical field
The utility model is related to injection mold field technology, hot nozzle structure in a kind of hot runner system is referred in particular to.
Background technology
Be molded in the molding of Chinese market plastic cement products at present and occupied extremely important position, and be molded be broadly divided into it is cold
Runner and hot flow path.Hot flow path has needle-valve and open two kinds of forms.In injection moulding process, injection molding machine gun nozzle is made by injection mouth
Sizing material enters hot runner system, its hot nozzle structure of hot runner system in the prior art is unreasonable due to designing, and leads to nozzle head
Sizing material on point is easy to be cooled, and to sizing material clogging occur, influences the normal work of hot nozzle, reduces the stabilization of work
Property.
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 a kind of hot flow path
Hot nozzle structure in system can effectively solve the problems, such as that existing hot nozzle is susceptible to sizing material clogging.
To achieve the above object, the utility model is using following technical solution：
Hot nozzle structure in a kind of hot runner system, includes ontology and heater；There is runner in the ontology, ontology
Front end face center, which is integrally extended forward, nozzle point, which there is plastic hole, the plastic hole to be connected to runner, and the periphery of ontology
Side has an annular mounting groove；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 periphery of the ontology is recessed with multiple mounting holes.
Preferably, the plastic hole is two opened each other.
The utility model has clear advantage and advantageous effect compared with prior art, specifically, by above-mentioned technology
Known to scheme：
By arranging the heater as heater element on the body, to drive the nozzle tip temperature of ontology to reach and can make in runner
Sizing material is in molten condition, avoids the occurrence of sizing material clogging, simple in structure, makes and installation is more convenient and small,
It is not easy to interfere with mold, flexibility is big；The risk for reducing hot nozzle leak adhesive eliminates the multiple accessories of traditional structure and is matched by screw thread
The phenomenon that conjunction；Repair and replacement are more simple and quick, and minimum to Influence of production, this product is mainly for high speed and high pressure Shooting Technique
Matched hot nozzle structure.
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.
Description of the drawings
Fig. 1 is the sectional view of the preferred embodiment of the utility model.
Description of drawing identification：
10, ontology 11, runner
12, nozzle point 121, plastic hole
13, annular mounting groove 14, mounting hole
15, snap ring 20, heater
30, sheath body is kept the temperature.
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.
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.
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 is kept molten by, and is then melted sizing material and is projected completion injection molding action from plastic hole 121.
The design focal point of the utility model is：By arranging the heater as heater element on the body, to drive ontology
Nozzle tip temperature reach sizing material in runner can be made to be in molten condition, avoid the occurrence of sizing material clogging, it is simple in structure, make and
Installation is more convenient and small, is not easy to interfere with mold, flexibility is big；The risk for reducing hot nozzle leak adhesive, eliminates biography
The phenomenon that system multiple accessories of structure pass through screw-thread fit；Repair and more simple and quick, this product minimum to Influence of production of replacement
Mainly for the matched hot nozzle structure of high speed and high pressure Shooting Technique.
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.
