Abstract
The utility model discloses a processing high rigidity injection molding machine screw rod for thermoplastic elastomer, including reinforced section, compression section and homogenizing section, be provided with profile of tooth spiral shell arris between compression section and the homogenizing section, be equipped with reverse spiral shell arris on the homogenizing section end, profile of tooth spiral shell arris does 10%~20% of screw rod totality length, the length of reverse spiral shell arris does 5%~15% of screw rod totality length, the draw ratio of screw rod is 30: 1. The utility model discloses can smash the material, destroy the fuse -element, strengthen melting plasticizing effect, improve the plastify ability, lengthen the dwell time of material in the barrel, make the goods surface smooth, improve the performance of product.
Description
Technical field
This utility model relates to injection molding apparatus field, particularly relates to a kind of processing high-hardness thermoplastic elastomer (TPE) note
Molding machine screw rod.
Background technology
Screw rod is the vitals of injection machine, and its effect is to carry plastics, be compacted, stir and press, all
These are all to be completed by screw rod rotation in barrel, and when screw rod rotates, plastics are for machine tube inner wall, screw channel
Bottom surface, between spiral shell rib pressure surface and plastics and plastics all can produce friction and mutually move.
Common injection machine is when the thermoplastic elastomer (TPE) relatively low for hardness, and plasticizing effect is fine.And for high rigidity
Thermoplastic elastomer (TPE), uses existing injection machine to process, and is commonly present the problem that fusion plastification is uneven, material dispersion is poor, very
To there will be the discontented glue phenomenon of product note, have a strong impact on the quality of plastic product.
Utility model content
The purpose of this utility model is to overcome defect of the prior art, it is provided that a kind of processing high-hardness thermoplastic elastic
Body screw in injection molding machine, its fusion plastification is effective, the most even production efficiency of material dispersion high.
For reaching above-mentioned purpose, this utility model is achieved through the following technical solutions:
A kind of processing high-hardness thermoplastic elastomer (TPE) screw in injection molding machine, including feeding section, compression section and homogenizing zone, described
Being provided with profile of tooth spiral shell rib between compression section and homogenizing zone, described homogenizing zone end is provided with reverse spiral shell rib, and described profile of tooth spiral shell rib is
The 10% ~ 20% of described screw rod overall length, the 5% ~ 15% of a length of described screw rod overall length of described reverse spiral shell rib, described spiral shell
The draw ratio of bar is 30:1.
Preferably, at least one during described profile of tooth spiral shell rib is straight dish profile of tooth spiral shell rib, swash plate profile of tooth spiral shell rib.
Preferably, the thickness (H) of described profile of tooth spiral shell rib is 5 ~ 12mm.
Preferably, the thickness (h) of described reverse spiral shell rib is 5 ~ 10mm.
Preferably, the angle (α) that described reverse spiral shell rib and screw stem water horizontal line are formed is 100 ° ~ 120 °.
The beneficial effects of the utility model:
Compared with prior art, screw rod of the present utility model is provided with profile of tooth spiral shell rib, it is possible to smashed by material, destroys
Melt, enhances fusion plastification effect, improves plasticizing capacity.Meanwhile, screw rod arranges reverse spiral shell rib, prolongs to a certain extent
Grow the material time of staying in machine barrel, made product surface smooth, improve the performance of product.

Fig. 1 is structural representation of the present utility model；
Fig. 2 is close-up schematic view of the present utility model；
Fig. 3 is the sectional view of this utility model profile of tooth spiral shell rib.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.
