Specific embodiment
In the following, with reference to attached drawing and specific embodiment, the utility model is described further, it is necessary to explanation is,
On the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
It is a kind of colour mixture ejection nozzle equipment of injection molding machine provided by the utility model shown in Fig. 1, which includes
Nozzle 1 and the nozzle flange 3 for being sheathed on 1 afterbody of nozzle offer cavity 11 inside nozzle 1, are equipped in the cavity 11 mixed
Colour solid 2, one end of the colour mixture body 2 and nozzle flange 3 are closely coupled, and one end in colour mixture body 2 is provided with colour mixture chamber 21, colour mixture chamber
21 are connected with nozzle flange 3, and several filter hole 22 of colour mixture body 2, the filter hole are provided through on the periphery wall of colour mixture body 2
22 connection cavitys 11 and colour mixture chamber 21.
The utility model is provided with colour mixture body 2 in the cavity 11 of nozzle 1, the first melt 7 can be filtered same
When, colour mixture further is carried out to the first melt 7, all kinds of iron filings, copper scale and the other impurities in the first melt 7 are filtered out,
Impurity is avoided to block mold glue-feeder or scratches mold hot flow, enhances plasticizing capacity, improves color blending effect, prevent from going out in product
Phenomena such as existing irregular colour, pigment figure.
Specifically, nozzle 1 is threadedly coupled with nozzle flange 3, and colour mixture body 2 is fixed on nozzle flange 3 by screwing nozzle 1
On so that the end face of colour mixture body 2 is closely connected with nozzle flange 3, and one end in colour mixture body 2 is provided with colour mixture chamber 21, nozzle
Flange 3 is connected with colour mixture chamber 21, and nozzle flange 3 is fixed on by screw 4 on barrel 5, nozzle 1, colour mixture body 2, nozzle flange
3rd, on the same axis, when injection acts, screw rod 6 pushes ahead generation height to the central axis of barrel 5 and screw rod 6 along barrel 5
Pressure promotes non-uniform first melt 7 of colour mixture to be directly entered from nozzle flange 3 in the colour mixture chamber 21 being arranged in colour mixture body 2, mixes
The each filter hole 22 set on colour solid 2 connects cavity 11 and colour mixture chamber 21 in nozzle 1, and under the promotion of high pressure, first
Melt 7 then via the filter hole 22 on colour mixture body 2, is flow in the cavity 11 in nozzle 1, then, the small iron in the first melt 7
The impurity such as block are screened out by the filter hole 22 on colour mixture body 2, while further colour mixture action is carried out in cavity 11, and it is equal to obtain colour mixture
The second even melt 8,8 free from admixture of the second melt and colour mixture finally obtained is uniform, and second melt 8 is from the cavity 11 of nozzle 1
It projects and enters mold cavity, finally mold corresponding product, the structure design of the utility model can improve the quality of product
And aesthetics.
First melt 7 flow to colour mixture body 2 through nozzle flange 3, and the setting of colour mixture chamber 21 can receive the institute for flowing through nozzle flange 3
There is the first melt 7, and the first melt 7 must could be entered by filter hole 22 on colour mixture body 2 in nozzle 1, the first melt 7 is in height
Pressure driving under the action of, continuously into colour mixture chamber 21, and be squeezed through each filter hole 22 and shunt, constantly into
Row compression and the process of release, so as to be sufficiently carried out colour mixture action, therefore, the setting of 22 diameter of filter hole can influence to mix
Colour solid 2 filters and the effect of colour mixture, and as preferred embodiment, filter hole 22 spreads all over the periphery for being disposed through colour mixture body 2
Wall is set by the number for increasing filter hole 22, can increase what the first melt 7 was acted by shunting during each filter hole 22 and mixing
Number and frequency are greatly improved its color blending effect, can also improve strainability, reduce the risk that colour mixture body 2 blocks.
In above-described embodiment, as preferred embodiment, the diameter of filter hole 22 is set to 2-3mm, filter hole 22 it is straight
Footpath should not set excessive, some volumes iron filings impurity less than normal otherwise can be screened out, so as to weaken filter effect；Meanwhile mistake
The diameter of filter opening 22 sets excessive resistance when can also reduce the first melt 7 by filter hole 22, reduces mixing dynamics, so as to shadow
Color blending effect is rung, reduces its plasticizing quality.Secondly, the aperture of filter hole 22 is also unsuitable too small, and otherwise filter hole 22 is easily by it
The impurity filtered out is blocked, and causes the blocking of colour mixture body 2, so as to influence injection action completion, and filter hole 22 is too small can not
It is convenient to clean.In the present embodiment, a diameter of 2-3mm of each filter hole 22 is set, it, also can be compared with while filtering function is realized
Complete the colour mixture to the first melt 7 well, eliminate the pigment figure problem generated when mixing uneven, ensure good plasticizing capacity and
Color blending effect.
In addition, the outer diameter of colour mixture body 2 is determined according to the size design of nozzle flange 3, in 22 a diameter of 2- of filter hole
In the case of 3mm, if colour mixture chamber 21 is too big, the first melt 7 in colour mixture body 2 can be to colour mixture under the squeezing action of screw rod 6
Body 2 causes greater back-pressure, influences the service life of colour mixture body 2；If colour mixture chamber 21 is too small, on the one hand it is unfavorable for the clear of colour mixture chamber 21
It washes, resistance when on the other hand can reduce the first melt 7 by filter hole 22 reduces mixing dynamics, influences color blending effect.Cause
This, colour mixture chamber 21 and the size design of filter hole 22 then need to keep certain relation, just can guarantee that the first melt 7 smooth can lead to
Filter hole 22 is crossed without blocking filter hole 22, and appropriate resistance can be generated to the first melt 7, so as to effectively being shunted and
Interflow eliminates the pigment figure problem generated due to mixing is uneven, ensures preferable color blending effect.Then, it is further preferred that colour mixture
The setting of 21 sectional area of chamber is no more than the sum of sectional area of all filter hole 22, to ensure that the first melt 7 can either swimmingly lead to
Cross each filter hole 22, be unlikely to because pressure difference or impurity there are due to generate it is stagnant idle, and can be by effectively shunting and and closing
Stream completes colour mixture action, and uniform second melt 8 of colour mixture is obtained in cavity 11.
Mixed color injecting nozzle of plastic jetting-moulding machine device provided by the utility model with filtering function, simple in structure, design is reasonable, tool
Have the advantages that impurity screening, color blending effect are good, dismounting cleaning is convenient, there is higher application and popularization value.
The above embodiment is only the preferred embodiment of the utility model, it is impossible to be protected with this to limit the utility model
Scope, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacing belongs to
In the utility model scope claimed.
