Specific embodiment
Refering to fig. 1~3, an embodiment of three color interlayer colour mixture ejaculator of the utility model, comprising a pedestal 1, three into
2, three mixture of colours seats 3 of material unit and three non-return injection nozzles 4.
The pedestal 1 includes three mounting portions 11 in triangle arrangement, specifically, the mounting portion 11 is equilateral triangle row
Column, wherein a mounting portion 11 is located above, other two mounting portion 11 is located below the left and right sides.Each mounting portion 11 defines
Out a front and back to horizontal-extending feeding-passage 10 and one from 11 peripheral surface of mounting portion extend inwardly and be connected to this into
Expect the feed inlet 101 in channel 10.The structure of the pedestal 1 is not particularly limited, as long as can be for the feed unit 2 and three color contamination
Seat 3 is closed to install.
The feed unit 2 is separately mounted to the mounting portion 11 of the pedestal 1, and as the mounting portion 11 is in three
Angle arrangement.Each feed unit 2 can drive including a charging axle 21 that the feeding-passage 10 is arranged in and one should
The power source 22 that charging axle 21 rotates.The charging axle 21 is a front and back to horizontal-extending screw rod.The power source 22 includes a horse
Link the actuated element 222 of the motor 221 and the charging axle 21 up to 221 and one.
Refering to Fig. 2~5, which is mounted on 2 front end of feed unit, and including a upright basal wall
31 and one from the basal wall 31 forward horizontal-extending discharging rod 32.It is respectively communicated with there are three being formed inside three mixture of colours seat 3
33, one, the conveying channel colour mixture channel 34 of the feeding-passage 10 and three interface channels 35.
Wherein, each conveying channel 33 has a first passage portion 331 being formed in the basal wall 31 and one
The second channel portion 332 for extending and being formed in the discharging rod 32 forward from the first passage portion 331.The first passage portion 331
It is connected to the feeding-passage 10, and the extending direction in first passage portion 331 is parallel with the in-plane of a vertical plane, that is,
It says, first passage portion 331 is not horizontal extension.The second channel portion 332 is from 331 one end of first passage portion horizontal extension facing forward.
The colour mixture channel 34 is formed in the discharging rod 32 and is located at 332 front side of the second channel portion, and facing forward penetrates with one
Outlet 341.The interface channel 35 is located at 332 front side of second channel portion, and the connection of 35 front end of interface channel should
Colour mixture channel 34, rear end are connected to second channel portion 332.The interface channel 35 is relative to the radial expansion in the second channel portion 332
Greatly.
The non-return injection nozzle 4 is located at the interface channel 35, also corresponds to be located at 33 front side of conveying channel.
Each non-return injection nozzle 4 includes a block face 41 towards the second channel portion 332, the block face 41 have it is several from front to back gradually
The oblique gear section 411 being obliquely extended towards the center height position in the second channel portion 332.
Refering to Fig. 3,6, each non-return injection nozzle 4 can be in the open position of a such as closed position of Fig. 3 and a such as Fig. 6
Between move.When the non-return injection nozzle 4 is located at the closed position, the corresponding conveying channel 33 is closed and blocks the conveying logical
Connection between road 33 and the colour mixture channel 34, when the non-return injection nozzle 4 is located at the open position, the corresponding conveying channel 33
It is connected to the colour mixture channel 34.More specifically, when which is located at the closed position, which more protrudes into this
Second channel portion 332, and oblique gear 411 block of section of the block face 41 is in the second channel portion 332 and the interface channel 35
Junction is connected to the second channel portion 332 not with the interface channel 35, and then blocks the conveying channel 33 and the colour mixture channel
Connection between 34.It is moved to when the non-return injection nozzle 4 is driven and forward the open position, the block face 41 no longer blocks this at this time
The junction in second channel portion 332 and the interface channel 35, it is mixed which can be connected to this via the interface channel 35
Chrominance channel 34.
Refering to Fig. 2,3,6, when the present embodiment is used in the injection of three colors, the granular feedstock of three kinds of different colours is put into respectively
The feed inlet 101 of the pedestal 1, the raw material are heated in the feeding-passage 10 and are in molten state, and can be by charging axle
21 rotations are promoted and are moved along feeding-passage 10, are entered back into conveying channel 33.Then assorted raw material is logical from the conveying respectively
The first passage portion 331 in road 33 enters second channel portion 332.And the original state of each non-return injection nozzle 4, due to being not affected by original
Material pushes forward, therefore is located at the closed position of Fig. 3, but after raw material flows into second channel portion 332, the stream of raw material generation
Body pressure can push the open position that the non-return injection nozzle 4 is moved along to Fig. 6, raw material can via the interface channel 35 with
The inner flow passage of the non-return injection nozzle 4 flows into the colour mixture channel 34.Therefore, the raw material of three kinds of different colours can be in the colour mixture channel
It is mixed in 34, then by 341 ejection formation of exit wound of bullet.
When stopping being sent into raw material, since the non-return injection nozzle 4 is no longer pushed forward, it will automatically reset and return to the pass
Closed position.It is noted that have the function of preventing raw material adverse current since the utility model is equipped with the non-return injection nozzle 4,
Even if the raw material in the colour mixture channel 34 has adverse current toward the phenomenon that the flowing of the conveying channel 33, but because raw material is towards 33 side of conveying channel
During adverse current, the Fluid pressure that raw material generates will push the closing that non-return injection nozzle 4 moves back to Fig. 3 backwards instead
Position, and then the front opening in the second channel portion 332 is sealed, it so prevents from raw material adverse current and enters conveying channel 33.
Plastic part of the utility model in addition to three colors can be made, it is monochromatic or double in can also be used to make certainly in implementation
One of feed unit 2 or in which two feed units 2 can be used only in color component at this time.Or three chargings
Unit 2 is used together, but all uses the raw material of same color.Or two of them feed unit 2 is using the original of same color
Material, another feed unit 2 use the raw material of other colors.There are many modes can allow when use, using upper flexible and convenient.
In conclusion can avoid raw material certainly by the channel design collocation non-return injection nozzle 4 of three mixture of colours seat 3
34 adverse current of colour mixture channel returns to conveying channel 33, so that the raw material of different colours be avoided to mix in conveying channel 33 and pollution.
And the feed unit 2 is arranged in pairs or groups three mixture of colours seat 3, and it can be with three colors, double-colored or monochromatic injection, using upper quite flexible side
Just.
As described above, only the embodiments of the present invention, when the utility model implementation cannot be limited with this
Range, i.e., it is all according to simple equivalent changes and modifications made by the utility model claims book and description, all still belong to
The scope of the utility model.
