Embodiment
Specific embodiment of the present utility model is described below, in order to which those skilled in the art understand
The utility model, it should be apparent that the utility model is not limited to the scope of embodiment, to the common skill of the art
For art personnel, if various change in the spirit and scope of the present utility model that appended claim limits and determines,
These changes are it will be apparent that all are created in the row of protection using the utility model of the utility model design.
According to one embodiment of the application, as Figure 1-5, the structure of the injection machine of this programme, including nozzle 1, mistake
Filter screen frame 2 and barrel 4, filtering screen frame 2 is embedded in the runner 5 of nozzle 1, and is connected by nozzle 1 with the runner 5 of barrel 4.
It is stainless steel to filter the material of screen frame 2, and its one end is location-plate 21, and location-plate 21 is close to the end face of nozzle 1.Positioning
The side of plate 21 is equipped with one layer of anti-network blocking 7, and the anti-material of network blocking 7 is stainless steel, and its mesh aperture is 0.8mm-2.0mm, preferably
For 1.8mm.
The acceleration stream part 24 of a tapered sieve-like is connected with the opposite side of location-plate 21, is accelerating the bottom panel of stream part 24
On be distributed with some tapered filter mesh 23, the aperture of filter mesh 23 is less than the mesh aperture in anti-network blocking 7.Accelerate stream part
24 inwalls are provided with some grooves 22, and groove 22 is in wavy, are uniformly distributed in the inwall for accelerating stream part 24, the depth of groove 22 edge material
4 sides of cylinder are deepened successively to the side of nozzle 1, and injection raw material is when flowing through groove 22, under the guiding of gravity, accelerates the stream of injection raw material
Speed.
Nozzle 1 is a hollow tubular structure, and filtering screen frame 2 is embedded in the runner 5 of nozzle 1.The end face of nozzle 1, the and of location-plate 21
Some screws 9 of position correspondence are equipped with anti-network blocking 7, screw 9 is inserted by screw 8, by anti-network blocking 7, filtering screen frame 2 and are penetrated
The three of mouth 1 fixes.
The outside of barrel 4 is evenly distributed with some heaters 3, and the screw rod 6 for promoting injection raw material is provided with the runner 5 of barrel 4.
In barrel 4 speed-change area 51, vortex 52 and stabilization area 53, the aperture of speed-change area 51 are sequentially provided with the runner 5 at nozzle 1
Minimum, when injection raw material enters speed-change area 51, due to the reduction in the aperture of runner 5, injection raw material is in the presence of identical thrust
Flowing will be speeded.The aperture of runner 5 of vortex 52 is more than the aperture of runner 5 of speed-change area 51, and vortex is had just enter into by speed-change area 51
52 injection raw material, because speed is larger, it will collide, enter with the injection raw material for also having not enough time to flow away in vortex 52
