Abstract
The utility model discloses a kind of liquid-state silicon gel cold runner sprue bushing, including nozzle body, the injection canal passed through for the sizing material of liquid and the cooling device cooled down to injection canal are provided with the nozzle body, the injection canal is exported with a sizing material, the maximum lateral dimensions of the sizing material outlet is less than or equal to 1mm, sizing material can be exported in injection mould by the sizing material during injecting operation, after the completion of injection operation, since sizing material outlet is very thin, and the surface tension of sizing material is generally all larger, therefore the sizing material in injection canal will not be exported from sizing material and flowed out, avoid wasting.
Description
Technical field
A kind of the utility model liquid-state silicon gel injection forming technical field, and in particular to liquid-state silicon gel cold runner sprue bushing.
Background technology
As silica gel product is in the extensive use of daily-use chemical industry, medical treatment, electronics and automobile and other industries, in order to realize that silica gel adds
Industrial high-efficient rate, high quality and low cost production, liquid silica gel injection molding technology have obtained rapid development.But common silica gel
The flow passage system of injection molding is Hot Runner System, and in injection process, nozzle and cavity are in together in the state of hot plate heating,
Sizing material temperature in sizing material and cavity in the rear nozzle of injection is raised and cured.Silica gel in nozzle can be to afterwards after curing
Injection reduces the work efficiency of injection, in addition, silica gel can not recycle after curing, therefore, this is also resulted in there are retardation
Waste to silica gel materials.
To solve the above-mentioned problems, some manufacturers set a cooling system on nozzle, make the sizing material in nozzle
Keep liquid.However, such scheme also generate one it is new the problem of, since the sizing material in nozzle is liquid, by mould
After opening and taking out the workpiece of die for molding, the sizing material in nozzle may flow outwardly and cause to waste.
Utility model content
In view of this, the purpose of this utility model is to provide one kind can make sizing material therein keep liquid, while again can
Prevent the liquid-state silicon gel cold runner sprue bushing that sizing material flows outwardly.
The utility model is to solve the technical solution that uses of its technical problem：
A kind of liquid-state silicon gel cold runner sprue bushing, including nozzle body, the glue for liquid is provided with the nozzle body
Expect the injection canal passed through and the cooling device cooled down to injection canal, the injection canal is exported with a sizing material, institute
The maximum lateral dimensions for stating sizing material outlet is less than or equal to 1mm.
Preferably, the sizing material outlet is in cylinder and its a diameter of 0.1-1mm.
Preferably, the nozzle body includes a mouth core and the muzzle being set on the mouth core, the injection canal
The mouth core inner is arranged on, the cooling device includes the cooling stream surrounded by the lateral wall of mouth core and the madial wall of muzzle
Road.
Preferably, being provided with the first Access Division on the lateral wall of the mouth core, it is provided with the madial wall of the muzzle
The second Access Division being adapted with first Access Division, first Access Division are mutually clamped to prevent with second Access Division
Mouth core is relatively rotated with muzzle.
Preferably, the sealing ring for closing gap between mouth core and muzzle is provided with the lateral wall of the mouth core.
Preferably, the coolant flow channel is serpentine-like.
The beneficial effects of the utility model are：It is provided with the utility model, on nozzle body and leads to for the sizing material of liquid
The injection canal and cooling device crossed, the cooling device can cool down to nozzle body, avoid the sizing material in injection canal from being heated
And solidify, there is sizing material outlet, the maximum lateral dimensions of sizing material outlet is less than or equal to 1mm, injects operation on injection canal
During sizing material can be exported by the sizing material in injection mould, after the completion of injecting operation, since sizing material exports very thin, and glue
The surface tension of material is generally all larger, therefore the sizing material in injection canal will not be exported from sizing material and flowed out, and avoid wasting.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the schematic cross-sectional view of the utility model；
Fig. 2 is the sectional view at line A-A in Fig. 1；
Fig. 3 is the partial enlarged view of part B in Fig. 1；
Fig. 4 is the top view of the utility model.
Embodiment
Referring to figs. 1 to Fig. 4, a kind of liquid-state silicon gel cold runner sprue bushing, including nozzle body, is provided with the nozzle body
The injection canal 11 passed through for the sizing material of liquid and the cooling device cooled down to injection canal, the injection canal 11 have
There is a sizing material to export 110, the maximum lateral dimensions of the sizing material outlet 110 is less than or equal to 1mm.It is cold after the completion of injecting operation
But device can cool down to nozzle body, avoid the sizing material in injection canal from being heated and solidify, further, since sizing material outlet is very
Carefully, and the surface tension of sizing material is generally all larger, therefore the sizing material in injection canal will not from sizing material export flow out, avoid wave
Take.
In the present embodiment, sizing material outlet 110 is in cylinder and its a diameter of 0.1-1mm.If the diameter of sizing material outlet is big
In 1mm, then sizing material may export 110 outflows from sizing material, if the diameter of sizing material outlet 110 is less than 0.1mm, and can be significantly
Reduce the efficiency of injection operation.
With reference to Fig. 1, nozzle body includes a mouth core 1 and the muzzle 2 being set on mouth core 1, injection canal 11 are arranged on mouth
Inside core 1, cooling device includes the coolant flow channel 4 surrounded by the lateral wall of mouth core 1 and the madial wall of muzzle 2.Reference Fig. 2, this
In embodiment, mouth core 1 is substantially in multi-edge column-shaped, and the endoporus of muzzle 2 is the circular hole coordinated with mouth core 1, passes through mouth core 1 and muzzle 2
Shape difference surround a snakelike coolant flow channel 4 between them.In order to avoid there is the situation of leak, mouth core 1 it is outer
The sealing ring 3 for closing gap between mouth core 1 and muzzle 2 is provided with side wall.Certainly, coolant flow channel 4 can also be spiral
Other applicable shapes such as shape, not limited to this.Cooling device can also use the common cooling devices such as heat exchanger.
With reference to Fig. 4, the first Access Division 12 is provided with the lateral wall of mouth core 1, is provided with the madial wall of muzzle 2 and first
The second Access Division 21 that Access Division 12 is adapted, the first Access Division 12 are clamped with 21 phase of the second Access Division to prevent mouth core 1 and mouth
Set 2 relatively rotates.Above-mentioned design can position fixed mouth core 1 and muzzle 2, avoid mouth core 1 and muzzle 2 from relatively rotating
And the sealing ring 3 between mouth core 1 and muzzle 2 is worn, then cause the bad phenomenons such as leak to occur.
The preferred embodiments of the utility model are these are only, as long as realizing the utility model aim with essentially identical means
Technical solution belong within the scope of protection of the utility model.
