The invention discloses a kind of hot nozzles of the colour changing of hot flow path, including hot nozzle ontology, needle-valve and sealing set: the needle is located in the hot nozzle ontology, the sealing set is located at the bottom of hot nozzle ontology, the hot nozzle inner body wall and the needle outer wall are airflow design, axis linear shrinkage of segment of the needle-valve below near-thermal nozzle ontology to the hot nozzle ontology, the least radius of the needle-valve is the 1/2 of the needle-valve maximum radius.Since hot nozzle inner body wall of the invention and the needle outer wall are airflow design, the needle-valve that cooperation segmentation is shunk realizes hot melt adhesive runner without dead angle, there is the phenomenon that sinuous flow when also reducing hot melt adhesive flowing, it is not obstructed so that hot melt adhesive flowing is smooth, to avoid wire drawing, improves production efficiency.In addition, setting up for locating piece is conveniently replaceable the hot nozzle of colour changing.
Description
Technical field
The present invention relates to Hot runner Technology field, in particular to a kind of hot nozzle of the colour changing of hot flow path.
Background technique
Hot flow path (Hot Runner Systems) is injected into the plastic pellet of thawing used in the injection mold
Heating component system in the type chamber of mold.Hot runner mould is to pass through the running channel of traditional type mold or shree plates mold and runner
Heating is crossed, a kind of brand-new construction for taking out runner and running channel is not needed when each forming.Hot flow path is doing by heating
Method guarantees that the plastics of runner and cast gate are kept molten by.Due near runner or center be equipped with heating rod and heating coil,
The entire runner for exporting to cast gate from injection molding machine nozzle makes the plastics in runner keep melting, after shutdown all in the condition of high temperature
Only need heating flow channel to required temperature when not needing generally to open runner taking-up condensate, then being switched on.Therefore, hot flow path technique
Sometimes referred to as hot manifold system, or referred to as runnerless mould is moulded.Some users are produced with the same mold has different colours
Same kind plastic, here it is the applications for having colour changing requirement.
Hot runner system is originating from without flow passage system, processing skill as an advanced plastic injection in injection industry
Art can trace back to the mid-term in last century even earlier in the universal use of western developed country.Hot flow path has many advantages,
Therefore many plastic mould factory 50% or more molds produced use Hot runner Technology.In China, this technology is nearly ten
Year is just really able to popularize in an all-round way and apply, with the continuous development of die industry, utilization of the hot flow path in your mold of plastics
Ratio also step up, but the ratio that generally also not up to external hot runner mould is big.
But in the prior art, generally existing hot nozzle injection port wire drawing phenomenon, seriously affects production efficiency and product matter
Amount.In addition, there is also the problems of the replacement hot nozzle inconvenience of colour changing, production efficiency is equally influenced.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of hot nozzle of the colour changing of hot flow path, the hot nozzle of the colour changing can avoid drawing
Silk improves production efficiency.
In order to solve the above-mentioned technical problem, the technical solution of the present invention is as follows:
A kind of hot nozzle of the colour changing of hot flow path, including hot nozzle ontology, needle-valve and sealing set: the needle is located at the hot nozzle sheet
In vivo, the sealing set is located at the bottom of hot nozzle ontology, and the hot nozzle inner body wall and the needle outer wall are airflow design,
Axis linear shrinkage of segment of the needle-valve below near-thermal nozzle ontology to the hot nozzle ontology, the least radius of the needle-valve are
The 1/2 of the needle-valve maximum radius.
Preferably, the internal diameter of the hot nozzle ontology is 1.5-3.5 times of the needle-valve maximum gauge.
It is furthermore preferred that the internal diameter of the hot nozzle ontology is 1.5-3 times of the needle-valve maximum gauge.
It is furthermore preferred that the internal diameter of the hot nozzle ontology is 1.5-2.5 times of the needle-valve maximum gauge.
Especially it is furthermore preferred that the internal diameter of the hot nozzle ontology is 2 times of the needle-valve maximum gauge.
Hot nozzle inner body wall and needle outer wall are airflow design, prevent dead angle, avoid hot melt adhesive constricted flow.
Preferably, it is equipped with locating piece in the sealing set, the top of the locating piece and the needle-valve bottom connection touch, fixed
Position part helps to find fixed position when replacing the hot nozzle of colour changing accurately, improves installation effectiveness.
By adopting the above technical scheme, since hot nozzle inner body wall and the needle outer wall are airflow design, cooperation segmentation
The needle-valve of contraction realizes hot melt adhesive runner without dead angle, the phenomenon that sinuous flow occurs when also reducing hot melt adhesive flowing, so that hot melt adhesive
Flow it is smooth be not obstructed, to avoid wire drawing, improve production efficiency.In addition, setting up for locating piece is conveniently replaceable the hot nozzle of colour changing.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
In figure, the hot nozzle ontology of 1-, 2- locating piece, 3- sealing set, 4- needle-valve.
Specific embodiment
Specific embodiments of the present invention will be further explained with reference to the accompanying drawing.It should be noted that for
The explanation of these embodiments is used to help understand the present invention, but and does not constitute a limitation of the invention.In addition, disclosed below
The each embodiment of the present invention involved in technical characteristic can be combined with each other as long as they do not conflict with each other.
As shown in Figure 1, a kind of hot nozzle of the colour changing of hot flow path, including hot nozzle ontology 1, needle-valve 4 and sealing set 3: needle 4 is located at
In hot nozzle ontology 1, sealing set 3 is located at the bottom of hot nozzle ontology 1, and hot 1 inner wall of nozzle ontology and 4 outer wall of needle are airflow design,
Axis linear shrinkage of segment of the needle-valve 4 below near-thermal nozzle ontology 1 to hot nozzle ontology 1, the least radius of needle-valve 4 are needle-valve maximums
The 1/2 of radius, the internal diameter of hot nozzle ontology 1 are 2 times of 4 maximum gauge of needle-valve.
Hot 1 inner wall of nozzle ontology and 4 outer wall of needle are airflow design, prevent dead angle, avoid hot melt adhesive constricted flow.
Wherein, locating piece 2 is equipped in sealing set 3, the top of locating piece 2 and 4 bottom connection of needle-valve touch, and locating piece 2 helps
Fixed position is found accurately when replacement colour changing hot nozzle, improves installation effectiveness.
When production operation, since hot 1 inner wall of nozzle ontology and 4 outer wall of needle are airflow design, the needle that cooperation segmentation is shunk
Valve 4 realizes hot melt adhesive runner without dead angle, when hot melt adhesive flows through, the phenomenon that sinuous flow occurs when can reduce hot melt adhesive flowing, so that hot
Melten gel flowing is smooth not to be obstructed, to avoid wire drawing, improves production efficiency.In addition, setting up for locating piece is conveniently replaceable colour changing heat
Installation speed is accelerated in positioning when nozzle.
In conjunction with attached drawing, the embodiments of the present invention are described in detail above, but the present invention is not limited to described implementations
Mode.For a person skilled in the art, in the case where not departing from the principle of the invention and spirit, to these embodiments
A variety of change, modification, replacement and modification are carried out, are still fallen in protection scope of the present invention.
