Description
Technical field
The utility model is related to screw rod field, more particularly to a kind of new wavy injection screw.
Background technology
Screw rod is the crucial Plasticized component of plastics processing plant equipment, and the quality of screw design quality is to plastic shaping
The height of process productivity ratio and the quality of shaped article quality suffer from strong influence.Each research institutions and enterprise input
Substantial amounts of manpower, financial resources and material resources are improved common screw structure and performance is improved, and various new screw rod is developed in succession, are such as divided
Release screw rod, barrier screw, bypass type screw rod, unsteady flow channel type screw rod etc..
Because the homogenizing zone of screw rod is longer, transportation section and plasticizing segment length is set to shorten relatively, heat of the material in screw rod is gone through
Journey is restricted, and the pile-up phenomenon of material is occurred, is had a strong impact on the raising of production capacity.For the hard polychlorostyrene second of heat endurance difference
The materials such as alkene, which are easy to produce thermal decomposition, causes material to be carbonized, and produces poison gas, injection is not carried out.It is hard in processing
Polrvinyl chloride product, which easily produces back-pressure backflow, can not ensure high filling film pressure.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of simple and reasonable, effective new wavy
Injection screw.
Technical problem to be solved in the utility model is achieved through the following technical solutions：
The new wavy injection screw of one kind of the present utility model, including screw body, the spiral shell that is located on screw body surface
Line, the screw body includes linkage section, and transportation section, fluxing zone, homogenizing zone, the linkage section is located at end, the transportation section
After linkage section, described transportation section core diameter of thread etc. is deep, and the fluxing zone is located at after transportation section, the fluxing zone screw thread
Bottom footpath is gradually big, and the homogenizing zone is located at after fluxing zone, and homogenizing zone bottom footpath etc. is deep.
Further, the linkage section is provided with the middle of symmetrical two keyways, two keyways and is provided with screwed hole.
Further, check ring is provided between the linkage section and transportation section, the check ring is external screw thread, and depth is
0.5mm, pitch is 6mm.
Further, the transportation section, fluxing zone, the pitch of the screw thread of homogenizing zone is more than the pitch of check ring.
Further, the homogenizing zone end is provided with screwed hole.
By such scheme, the utility model at least has advantages below：
The new wavy injection screw of one kind of the present utility model, is particularly suitable for processing the PVC-U thing of thermal sensitivity difference
Material, and have positive effect to improving product quality, the characteristics of with shaping shape complicated product.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and being practiced according to the content of specification, with preferred embodiment of the present utility model and coordinate accompanying drawing detailed below
Describe in detail bright as after.

Embodiment
With reference to the accompanying drawings and examples, embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not limited to scope of the present utility model.
Referring to shown in Fig. 1-5, a kind of new wavy injection screw, including screw body, be located on screw body surface
Screw thread, it is characterised in that screw body includes linkage section 1, transportation section 2, fluxing zone 3, homogenizing zone 4, linkage section 1 is located at end,
Transportation section 2 is located at after linkage section 1, and core diameter of thread of transportation section 2 etc. is deep, and fluxing zone 3 is located at after transportation section 2, the screw thread of fluxing zone 3
Bottom footpath is gradually big, and homogenizing zone 4 is located at after fluxing zone 3, and homogenizing 4 sections of bottoms footpath etc. is deep.
Linkage section 1 is provided with the middle of symmetrical two keyways 5, two keyways 5 and is provided with screwed hole.
Check ring 6 is provided between linkage section 1 and transportation section 2, check ring 6 is external screw thread, and depth is 0.5mm, and pitch is
6mm。
Transportation section 2, fluxing zone 3, the pitch of the screw thread of homogenizing zone 4 is more than the pitch of check ring 6.
4, homogenizing zone end is provided with screwed hole.
The purpose of this utility model is that the disadvantages mentioned above and deficiency overcome present in prior art, and provides a kind of band
There is the high productive capacity of threaded screw head of the wavy screw rod equipped with check ring, do not produce thermal decomposition, it is adaptable to process hard polychlorostyrene second
The wave-like high effective injection screw stem of alkene the part with complicated structure.Screw body part by transportation section 2 have contoured shape fluxing zone 3 and segment length very
Short homogenizing zone 4 is constituted, and has a crest and trough in each pitch of fluxing zone 3, when rotation of the material with screw rod
When turning to enter at crest, then by Strong shear and extruding, but with the rotation of screw rod, the partial material is fallen into larger again
The trough volume of material of volume is bulk and is released out, has reached the purpose of low-temperature plasticizing.
