The utility model discloses spiral hot nozzle structure in a kind of hot runner system, includes ontology, heater, sealing ring and nozzle point;The front/rear end of the ontology is formed through runner, and the circumferential lateral surface of ontology is recessed with spiral groove, is extended spirally before and after the spiral groove;The heater is embedded in spiral groove;The sealing ring is installed on the front end of ontology, and sealing ring has a pilot hole position;The nozzle point is embedded in pilot hole position, and one end of nozzle point is connected to runner, and the other end of nozzle point is connected to the plastic hole face of sealing ring.By being provided with spiral groove, and heater is coordinated to be set in spiral groove so that heater heating effect obtains effective transmission of empty calory loss, ensures that the sizing material on nozzle head point is not easy to be cooled, avoid the occurrence of sizing material clogging, the normal work for ensuring hot nozzle greatly improves the stability of work, and then improves injection efficiency, and overall structure is simple, it is easily achieved, it is at low cost, it is conducive to wide popularization and application.

Description

Spiral hot nozzle structure in hot runner system
Technical field
The utility model is related to injection mold field technology, spiral 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 point On sizing material be easy cooled, to sizing material clogging occur, influence the normal work of hot nozzle, reduce the stability of work.
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 Spiral hot nozzle structure, can effectively solve the problems, such as that existing hot nozzle is susceptible to sizing material clogging in system.
To achieve the above object, the utility model is using following technical solution:
Spiral hot nozzle structure in a kind of hot runner system includes ontology, heater, sealing ring and nozzle point;This The front/rear end of body is formed through runner, and the circumferential lateral surface of ontology is recessed with spiral groove, and spiral is prolonged before and after the spiral groove It stretches;The heater is embedded in spiral groove;The sealing ring is installed on the front end of ontology, and sealing ring has a pilot hole position;The nozzle Point is in pilot hole position, and one end of nozzle point is connected to runner, and the other end of nozzle point is connected to the plastic hole face of sealing ring.
Preferably, the screw pitch of the spiral groove is sequentially increased from front to back.
Preferably, the body peripheral side is sheathed on muff, which wraps heater.
Preferably, the nozzle point is beryllium copper material.
The utility model has clear advantage and advantageous effect compared with prior art, specifically, by above-mentioned technology Known to scheme:
By being provided with spiral groove, and heater is coordinated to be set in spiral groove so that heater heating effect obtains The effective transmission lost to empty calory ensures that the sizing material on nozzle head point is not easy to be cooled, avoids the occurrence of sizing material clogging, really The normal work of thermal protection nozzle greatly improves the stability of work, and then improves injection efficiency, and overall structure is simple, is easy to It realizes, it is at low cost, it is conducive to wide popularization and application.
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.

Fig. 1 is the partial cross-sectional view of the preferred embodiment of the utility model.
Description of drawing identification:
10, ontology 11, runner
12, spiral groove 20, heater
30, sealing ring 31, pilot hole position
32, plastic hole 40, nozzle point
50, muff.
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, heater 20, sealing ring 30 and nozzle point 40.
The front/rear end of the ontology 10 is formed through runner 11, and the circumferential lateral surface of ontology 10 is recessed with spiral groove 12, It is extended spirally before and after the spiral groove 12;In the present embodiment, which is aluminum alloy material, the spiral shell of the spiral groove 12 Away from being sequentially increased from front to back.
The heater 20 is embedded in spiral groove 12;In the present embodiment, which is heating wire, also, described 10 circumferential lateral surface of ontology is sheathed on muff 50, which wraps heater 20, to avoid thermal loss.
The sealing ring 30 is installed on the front end of ontology 10, and sealing ring 30 has a pilot hole position 31;Nozzle point 40 is embedded in dress In distribution position 31, one end of nozzle point 40 is connected to runner 11, and the other end of nozzle point 40 is connected to 32 face of plastic hole of sealing ring 30. In the present embodiment, the nozzle point 40 is beryllium copper material, can effectively accelerate hot transmission, also, sealing is stretched out in the front end of nozzle point 40 The front end face of ring 30.
The operation principle that the present embodiment is described in detail is as follows:
In use, melting sizing material is into after air stream enter runner 11, which generates heat so that the sizing material in runner 11 is kept Molten condition, then, sizing material project by nozzle point 40 and complete injection molding action.
The design focal point of the utility model is:By being provided with spiral groove, and heater is coordinated to be set to spiral groove In so that heater heating effect obtains effective transmission of empty calory loss, and it is cold to ensure that the sizing material on nozzle head point is not easy But, sizing material clogging is avoided the occurrence of, it is ensured that the normal work of hot nozzle greatly improves the stability of work, and then improves injection molding Efficiency, and overall structure is simple, it is easy to accomplish, it is at low cost, it is conducive to wide popularization and application.
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.
