Description
Technical field
The utility model is related to injection mold field technologies, refer in particular to a kind of novel valve needle guide ring mounting structure.
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 required to cooperation and adopts when installing needle
Melting sizing material is caused to hinder, influences injection molding operation however, current guide ring is unreasonable due to designing with guide ring.
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 new type of valve
Needle guide ring mounting structure, can effectively solve existing guiding ring design it is unreasonable cause to melting sizing material cause obstruction to ask
Topic.
To achieve the above object, the utility model is using following technical solution：
A kind of novel valve needle guide ring mounting structure includes ontology, guide ring and needle；The upper and lower end face of the ontology
It is formed through runner, the bottom of ontology is equipped with nozzle point by a sealing ring, which is connected to runner；The guide ring is embedded in
It in runner and is butted on the upper surface of nozzle point, guide ring includes outer shroud, and the inner circumferential side of outer shroud, which is integrally extended, multiple companies
Synthetism position, the inner end of multiple connection position of bone, which is enclosed, is configured to endoporus, and fan-shaped slot, each fan are formed between the adjacent two connections position of bone
Shape slot is connected to endoporus；The needle is set in runner, and needle is adapted with endoporus, and the lower end of needle extends downwardly nozzle
Point.
Preferably, the connection position of bone is four, and four connection position of bone intervals are uniformly arranged, accordingly, the sector slot
It is four.
Preferably, the upper end outer diameter of the needle is more than lower end outer diameter.
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：
There are multiple connection position of bone by integrally extending in the inner circumferential side of outer shroud, configuration is enclosed in the inner end of multiple connection position of bone
At endoporus, it is formed with fan-shaped slot between the adjacent two connections position of bone, plays resistance of the guide ring for reducing needle to melting sizing material
Hinder so that the more existing guide ring of through flow hole between outer shroud, endoporus has better flow efficiency, is brought just for injection molding operation
Profit.
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 use state sectional view of the preferred embodiment of the utility model；

Specific implementation mode
It please refers to shown in Fig. 1 and Fig. 2, that show the concrete structures of the preferred embodiment of the utility model, include
Ontology 10, guide ring 20 and needle 30.
The upper and lower end face of the ontology 10 is formed through runner 11, and the bottom of ontology 10 is equipped with one by a sealing ring 40
Nozzle point 50, nozzle point 50 are connected to runner 11；In the present embodiment, which is aluminum alloy material, and the nozzle point 50 is beryllium copper
Material, also, the sealing ring 40 and ontology 10 are screwed together fixation, the upper end of nozzle point 50 be clamped in sealing ring 40 and ontology 10 it
Between, the lower end of nozzle point 50 extends downwardly outside sealing ring 40.
The guide ring 20 is embedded in runner 11 and is butted on the upper surface of nozzle point 50, and guide ring 20 includes outer shroud 21, outside
The inner circumferential side of ring 21, which is integrally extended, multiple connection position of bone 22, and the inner end of multiple connection position of bone 22, which is enclosed, is configured to endoporus 23,
Fan-shaped slot 24 is formed between the adjacent two connections position of bone 22, each sector slot 24 is connected to endoporus 23；In the present embodiment,
The connection position of bone 22 is four, and four connection position of bone 22 are spaced uniform arrangement, and accordingly, which is four.
The needle 30 is set in runner 11, and needle 30 is adapted with endoporus 23, and the lower end of needle 30 extends downwardly nozzle
Point 50.In the present embodiment, the upper end outer diameter of the needle 30 is more than lower end outer diameter.
The operation principle that the present embodiment is described in detail is as follows：
In use, then melting sizing material, enters nozzle point 50 into air stream enter runner 11 by fan-shaped slot 24, then, from nozzle point
50 project.
The design focal point of the utility model is：There are multiple connection position of bone by integrally extending in the inner circumferential side of outer shroud,
The inner end of multiple connection position of bone, which is enclosed, is configured to endoporus, is formed with fan-shaped slot between the adjacent two connections position of bone, plays reduction valve
Obstruction of the guide ring of needle to melting sizing material so that the more existing guide ring of through flow hole between outer shroud, endoporus has preferably
Flow efficiency offers convenience for injection molding operation.
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,
