Description
Technical field
This utility model relates to injection machine technical field, especially relates to a kind of screw in injection molding machine structure.
Background technology
Screw rod in injection machine is important key components and parts, plastic cement solid feed could carry out melting, plastifying, carry and complete through injection machine the integrated molding making of plastic product such as bottle packaging, crisper etc. by screw rod turning effort in barrel, wherein the Main Function of screw rod is for fear of to the fusing of plastic material and stirring, and extrusion molten plastic liquid has advanced injection, it is seen that screw-rod structure is for being molded the importance of quality.In current existing injection machine, problem due to screw-rod structure, use that generally to there is molten plastic fluid mixing uneven in cylinder, fluid foods homogeneous dispersion is not enough and feeds the shortcomings such as slow, tend to cause local plastic cement fluid that coking occurs, thus having a strong impact on the quality of plastic, a kind of new screw overcomes the work defect of above-mentioned injection machine.
Utility model content
In order to overcome above-mentioned existing technological deficiency, the purpose of this utility model is that providing a kind of is favorably improved plastics melt flow stream blanking velocity and screw in injection molding machine structure of mixing dispersion uniformity in cylinder.
In order to achieve the above object, this utility model 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 of feeding intake, the compression section of stirring, metering section, stirring section, thread segment and head in advance it is disposed with on described screw body, described stirring section is provided with stirring sheet, spiral rib sheet it is provided with in the described compression section of stirring in advance, have through hole on described rib sheet, the screw body between adjacent ribs sheet has the otch contrary with the rib sheet hand of spiral.
The principle of the technical program is: on the one hand, by the otch arranged on the body of rod of screw rod and the rib sheet hand of spiral is contrary, make molten plastic fluid extruding advance in fluid be internally formed local mixed flow, and in screw rod rotation process, form lateral shear, make molten plastic fluid mixing evenly, and effectively raise homogeneous dispersion；On the other hand through hole is set on rib sheet, adds the flow channel of melt flow stream, thus improve the speed of charging.
Compared with prior art, the beneficial effects of the utility model are: this utility model structure is improved simple and clear, easily realize in technique, by the improvement to screw-rod structure, effectively overcoming plastic liquid present in injection machine long-play mixing uneven in cylinder, fluid foods homogeneous dispersion is not enough and the charging shortcoming such as slowly, improves quality and the yield rate producing product, and extend the maintenance maintenance period of injection machine, rate when improve work.
This programme is that other optimizations also include with optimal way:
1, described stirring sheet triangularity shape, and arrange towards metering section azimuthal tilt, it is favorably improved the extrusion capacity of molten plastic fluid, thus improves charging rate.
2, the through hole that is arranged at described on rib sheet becomes dislocation to arrange, contributes to improving further molten plastic fluid mixing uniformly and material dispersion homogeneity.
3, the hand of spiral on described thread segment is identical with the hand of spiral of rib sheet, is favorably improved the extrusion capacity of molten plastic fluid, thus improves charging rate.
Accompanying drawing explanation
This utility model will illustrate by example and with reference to the appended drawing, wherein:
Fig. 1 is structural representation of the present utility model.
Labelling in figure: the section of feeding intake 1, compression pre-stirring section 2, metering section 3, stirring section 4, thread segment 5, head 6, stirring sheet 7, rib sheet 8, through hole 9, otch 10.
Detailed description of the invention
Below in conjunction with the accompanying drawings, this utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
Embodiment 1, as shown in Figure 1, the technical program is a kind of screw in injection molding machine structure, including screw body, being disposed with the section of feeding intake 1, compression pre-stirring section 2, metering section 3, stirring section 4, thread segment 5 and head 6 on described screw body, described stirring section 4 is provided with stirring sheet 7, the described compression section of stirring 2 in advance is provided with spiral rib sheet 8, have through hole 9 on described rib sheet, the screw body between adjacent ribs sheet 8 has the otch 10 contrary with rib sheet 8 hand of spiral.
In plastic material (granule or the powder) section of feeding intake certainly enters screw rod place seating nipple; due to screw body by Resistant heating to higher problem; can carry out material is added heat fusing in the section of feeding intake 1; owing to screw body continues rotation under the drive of motor; the plastic cement molten mass formed in the section of feeding intake 4 enters in the space between compression pre-stirring section 2 and seating nipple inwall, then is pushed by the rib sheet 8 rotated and stirred.
Due to the otch 10 arranged on the body of rod of compression pre-stirring section 2 and the rib sheet hand of spiral is contrary, molten plastic internal fluid is made to form local mixed flow, and in screw rod rotation process, form lateral shear, improve the mixing uniformity of melt flow stream and scattered homogeneity, through hole 9 is set on rib sheet 8 simultaneously, fluid pressurized in compression process can add the flow channel of melt flow stream by through hole 9, thus improves the speed of charging, eventually passes the end of thread 5 and head 6 extrudes into mould and completes injection.
Embodiment 2, carries out decision design, described stirring sheet 7 triangularity shape to stirring sheet 7 on the basis of embodiment 1, and arranges towards metering section 3 azimuthal tilt, be favorably improved the extrusion capacity of molten plastic fluid, thus improve charging rate.
Embodiment 3, carries out decision design to the structure of rib sheet 8 on the basis of embodiment 1, described in the through hole 9 one-tenth dislocation that is arranged on rib sheet 8 arrange, contribute to improving further molten plastic fluid mixing uniformly and material dispersion homogeneity.
Embodiment 4, is optimized design on the basis of embodiment 1 to the end of thread 5, and the hand of spiral on described thread segment 7 is identical with the hand of spiral of rib sheet 8, is favorably improved the extrusion capacity of molten plastic fluid, thus improves charging rate.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
