As shown in figure 1, a kind of one embodiment of flow liner generating means of the present invention, including：
Fixed die plate of injection molding machine 1, injection expects pipe 2, base 3, plunger barrel 4, hopper 5 and oil cylinder 7, in the plunger barrel 4 Portion is hollow to form plunger compartment 41, in the plunger compartment 41 activity one plunger rod 42 is set, the oil cylinder 7 drives with the plunger rod 42 Dynamic connection, the plunger rod 42 is movable in plunger compartment 41 under the driving of oil cylinder 7, and the hopper 5 and the plunger barrel 4 connect Logical, specifically, oil cylinder 7 has oil cylinder fixed plate 71, and oil cylinder fixed plate 71 is fixedly installed on the top of plunger barrel 4, for propping up Oil cylinder 7 is supportted, oil cylinder fix bar 72 is set in oil cylinder fixed plate 71, the motion of the support cylinder 7 of oil cylinder fix bar 72, hopper 5 goes out Mouth is fixed in oil cylinder fixed plate 71, and the outlet of hopper 5 connects with the plunger compartment 41 of plunger barrel 4, plunger barrel 4 described in top Outside is provided with heating circle 45, and the base 3 is connected with the fixed die plate of injection molding machine 1, as shown in Fig. 2 the base 3 is provided with Colo(u)r mixer 31 and shunting net 32, the colo(u)r mixer 31 has first interface 311, the interface 313 of second interface 312 and the 3rd, described First interface 311 connects with injection expects pipe 2, and the second interface 312 connects with the plunger compartment 41, the 3rd interface 313 Connected with the shunting net 32, nozzle 6 is provided with outside the shunting net 32, specifically, the colorant of different colours fills successively It is loaded in hopper 5, for colorant by being plastified during plunger compartment 41 by the heating of heating circle 45, plunger rod 42 leads to the colorant after plasticizing Cross second interface 312 and squeeze into colo(u)r mixer 31, the major ingredient for being molded expects pipe 2 enters colo(u)r mixer 31 through first interface 311, due to different face The colorant of color is not agitated in plunger compartment 41, therefore the colorant of different colours will not mix, and has clear obvious boundary, During by second interface 312, because the bore of second interface 312 is smaller, colorant is set to be uniformly injected into colo(u)r mixer 31, and from first Interface 311 is uniformly injected into major ingredient mixing, and colorant and major ingredient uniformly mix in colo(u)r mixer, forms the uniform and different color of color Block, color lump are transported to shunting net 32 through the 3rd interface 313, and the mesh that color lump is split net 32 is partitioned into a plurality of color and is uniformly distributed Vitta, vitta quickly reaches mould 9 through nozzle 6, and the vitta of the ejection of high speed is disturbed in a mold, ultimately forms various each The flow liner that sample varies in color, the product color being molded by the present invention is distinct, uniform, flow liner excellent.It is noted that Petrol station 74 is connected by choke valve 75 with oil cylinder 7, is pushed speed by adjust the control cylinder 7 of choke valve 75, can effectively be adjusted The flow velocity of colorant in plunger compartment 41, so as to meet the mixing of a variety of colors ratio, on the other hand, injection machine and petrol station 74 are led to respectively Cross signal wire to be connected with control device, when control device control injection machine work, while also can control petrol station 74 to drive plunger Bar 42 works asynchronously so that major ingredient and colorant can synchronously enter colo(u)r mixer 31.
Further, the base 3 is additionally provided with check valve 33, and the plunger compartment 41 passes through check valve 33 and the colour mixture The second interface 312 of device 31 connects, and so further can effectively control colorant to enter colo(u)r mixer 31, while also avoid colo(u)r mixer 31 Interior colorant flows backwards.
Further, heating bar 34 is additionally provided with the base 3, nozzle heating circle 35 is provided with outside the nozzle 6, It is noted that circle 35 and heating circle 46 electrically connect with temperature-controlled cabinet 38 as shown in figure 3, heating bar 34, nozzle generate heat, send out The heating of hot pin 34 and nozzle heating circle 35, ensure that colorant and major ingredient are keeping plastifying state during colour mixture and injection.
It is noted that a kind of flow liner generating means of the present invention are easy for installation, without being carried out to existing injection machine Transformation, and without independent customized development, cost is cheap, and can have multiple mounting modes with injection machine as needed：
As shown in figure 1, the injection expects pipe 2 has an expects pipe flange 21, the base 3 by an adpting flange 8 with it is described Expects pipe flange 21 connects, in a second embodiment of the present invention, as shown in figure 4, the base 3 can also be with the expects pipe method Orchid 21 is directly fixedly connected.
As shown in figure 5, the 3rd embodiment of the present invention, the injection expects pipe 2 is respectively arranged at described with the base 3 The both sides of fixed die plate of injection molding machine 1, the injection expects pipe 2 are connected with the fixed die plate of injection molding machine 1 respectively with the base 3
As shown in fig. 6, the 4th embodiment of the present invention, the base 3 and the directly fixed company of the fixed die plate of injection molding machine 1 Connect, it should be appreciated that above-described embodiment belongs to presently preferred embodiments of the present invention, is not intended to limit the invention, all at this Modification, replacement within the creation intention of invention belong to protection scope of the present invention.
Present invention also offers a kind of flow liner generation method, as shown in fig. 7, comprises following steps：
Step S1, colorant and major ingredient are distinguished into heating plasticizing；
The purpose of this step is to distinguish in colorant and major ingredient, avoids mixing too early, and color is distinguished unobvious, another The ratio of the easily controllable colorant of aspect and major ingredient, is easily adjusted flow liner effect.
Step S2, colorant is squeezed into by colo(u)r mixer by plunger rod；
By this step so that colorant is directly entered colo(u)r mixer, between colorant and without mixing so that different colours Boundary line is clear after colorant enters colo(u)r mixer, distinguishes and becomes apparent between color.
Major ingredient in step S3, colorant and simultaneous implantation to colo(u)r mixer is uniformly mixed in colo(u)r mixer；
Colorant and major ingredient simultaneous implantation are kept into colo(u)r mixer so that colorant and major ingredient keep stable ratio uniform mixing, So that the chromatic zones between mixed color lump shows clearly.
Step S4, a plurality of vitta feeding will be uniformly divided into by shunting net in the mixed colorant of colo(u)r mixer and major ingredient and penetrated Mouth；
In this step, color lump is split the mesh of net and is partitioned into the equally distributed vitta of a plurality of color, the face on vitta Color is interspersed.
Step S5, nozzle spray into vitta in mould, complete injection.
Vitta is disturbed being sprayed at high speed after nozzle in a mold, ultimately forms the stream of all kinds to vary in color Line, the product color being molded by said process is distinct, uniform, flow liner excellent.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention God any modification, equivalent substitution and improvements made etc., should be included in the scope of the protection with principle.
