Description
Technical field
The present invention relates to injection machine technical field, more particularly, to a kind of screw in injection molding machine structure.
Background technology
Screw rod in injection machine is important key components and parts, the integrated molding that could be melted plastic cement solid feed by turning effort of the screw rod in barrel, plastify, convey and complete plastic product such as bottle packaging, crisper etc. by injection machine makes, wherein the main function of screw rod is for fear of the fusing and stirring to plastic material, and the advance of extrusion molten plastic liquid completes injection, it is seen that importance of the screw-rod structure for injection quality.In current existing injection machine, the problem of due to screw-rod structure, generally existing molten plastic fluid kneads uneven in cylinder in use, the shortcomings of fluid foods homogeneous dispersion deficiency and slow charging, tend to cause local plastic cement fluid coking occur, so as to have a strong impact on the quality of plastic products, therefore urgently a kind of new screw overcomes the work defect of above-mentioned injection machine.
The content of the invention
In order to overcome above-mentioned existing technological deficiency, it is an object of the invention to provide a kind of screw in injection molding machine structure for being favorably improved plastic molten melt fluid blanking velocity and scattered uniformity of mixing in cylinder.
In order to achieve the above object, the present invention is achieved through the following technical solutions：
The technical program is a kind of screw in injection molding machine structure, including screw body, the section that feeds intake, the pre- stirring section of compression, metering section, stirring section, thread segment and head are disposed with described screw body, described stirring section is provided with stirring sheet, spiral rib piece is provided with the pre- stirring section of compression, through hole is provided with described rib piece, the otch opposite with the rib piece hand of spiral is provided with the screw body between adjacent ribs piece.
The principle of the technical program is：On the one hand, by setting the otch opposite with the rib piece hand of spiral on the body of rod of screw rod, molten plastic fluid fluid in extruding is promoted is set to be internally formed local mixed flow, and form lateral shear in screw rod rotation process, make the mixing of molten plastic fluid evenly, and effectively raise homogeneous dispersion；On the other hand through hole is set on rib piece, the flow channel of melt flow stream is added, so as to improve the speed of charging.
Compared with prior art, the beneficial effects of the invention are as follows：Structure of the present invention is improved simple and clear, easily realized in technique, pass through the improvement to screw-rod structure, effectively overcome plastic liquid present in injection machine long-play kneaded in cylinder it is uneven, the shortcomings of fluid foods homogeneous dispersion deficiency and slow charging, the quality and yield rate of production product are improved, and extends the maintenance maintenance period of injection machine, rate when improving work.
This programme is that other optimizations also include with preferred embodiment：
1st, the stirring sheet triangularity shape, and set towards metering section azimuthal tilt, the extrusion capacity of molten plastic fluid is favorably improved, so as to improve charging rate.
2nd, the through hole being arranged on rib piece is arranged into dislocation, is helped further to improve molten plastic fluid and is kneaded uniformly and material dispersion homogenieity.
3rd, the hand of spiral on the thread segment is identical with the hand of spiral of rib piece, is favorably improved the extrusion capacity of molten plastic fluid, so as to improve charging rate.
Brief description of the drawings
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein：
Fig. 1 is the structural representation of the present invention.
Marked in figure：The section that feeds intake 1, the pre- stirring section 2 of compression, metering section 3, stirring section 4, thread segment 5, head 6, stirring sheet 7, rib piece 8, through hole 9, otch 10.
Embodiment
Below in conjunction with the accompanying drawings, the present invention is described in detail.
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with drawings and Examples, the present invention will be described in further detail.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
Implement 1, as shown in Figure 1, the technical program is a kind of screw in injection molding machine structure, including screw body, the section 1 that feeds intake, the pre- stirring section 2 of compression, metering section 3, stirring section 4, thread segment 5 and head 6 are disposed with described screw body, described stirring section 4 is provided with stirring sheet 7, the pre- stirring section 2 of compression and is provided with spiral rib piece 8, through hole 9 is provided with described rib piece, the otch 10 opposite with the hand of spiral of rib piece 8 is provided with the screw body between adjacent ribs piece 8.
Work as plastic material（Particle or powder）Enter from the section that feeds intake where screw rod in seating nipple, because screw body is by Resistant heating to higher problem, the heating melting to material can be carried out in the section 1 that feeds intake, because screw body continues rotation under the drive of motor, enter in the plastic cement molten mass for the formation of section 4 that feeds intake in the space between the pre- stirring section 2 of compression and seating nipple inwall, then push and stir by the rib piece 8 of rotation.
Due to setting the otch 10 opposite with the rib piece hand of spiral on the body of rod of the pre- stirring section 2 of compression, molten plastic internal fluid is set to form local mixed flow, and form lateral shear in screw rod rotation process, improve the mixing uniformity and scattered homogenieity of melt flow stream, through hole 9 is set on rib piece 8 simultaneously, fluid is pressurized in compression process the flow channel of melt flow stream is added by through hole 9, so as to improve the speed of charging, eventually pass the end of thread 5 and head 6 extrudes into mould and completes injection.
Embodiment 2, carries out decision design, the triangularity shape of stirring sheet 7 on the basis of embodiment 1 to stirring sheet 7, and is set towards the azimuthal tilt of metering section 3, the extrusion capacity of molten plastic fluid is favorably improved, so as to improve charging rate.
Embodiment 3, carries out decision design on the basis of embodiment 1 to the structure of rib piece 8, and the through hole 9 being arranged on rib piece 8 is arranged into dislocation, helps further to improve molten plastic fluid and kneads uniformly and material dispersion homogenieity.
Embodiment 3, the hand of spiral optimized on the basis of embodiment 1 to the end of thread 5 on design, the thread segment 7 is identical with the hand of spiral of rib piece 8, is favorably improved the extrusion capacity of molten plastic fluid, so as to improve charging rate.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, any modifications, equivalent substitutions and improvements made within the spirit and principles of the invention etc., should be included in the scope of the protection.
