Abstract
The utility model discloses a kind of injection machine injection screw, comprise the screw body of outer surface distributing auger sheet, described screw body comprises feeding section, compression section and homogenizing zone successively, the flight of described compression section is helical gear sheet, and the two sides of described helical gear sheet are evenly equipped with some protruding blocks.By the way, the utility model can strengthen melt mixing and plasticizing fast, and improves melt plasticizing quality; The melt of low temperature homogeneous and stable extruding and high plasticizing capacity can be obtained simultaneously.
Description
Technical field
Injection molding art of the present invention, particularly relates to a kind of injection machine injection screw.
Background technology
Injection moulding is a kind of important method that thermoplastic plastics shaping manufactures, and injection screw is the key components and parts in screw injection device Plasticized component, it rotates in the machine barrel of injection machine, and Main Function is exactly solid-state plastic particles or plastics powder carried out carrying, compacting, fusion plastification, evenly, store metering.
In the universal plasticized screw of existing injection machine, its raising plasticizing capacity and mixing ability mainly adopt structural parameters and the physical dimension parameter of the screw thread changing flight, realize as changed draw ratio, screw zones pitch, spiral shell rib width, spiral groove depth and compression ratio.But, these parameters of only single change, the effect produced is often obvious not; Cause melting efficiency low, melt plasticizing bad, molten temperature is unstable, the shortcomings such as melten gel ability is low.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of injection machine injection screw, can strengthen melt mixing and plasticizing fast, and improve melt plasticizing quality; The melt of low temperature homogeneous and stable extruding and high plasticizing capacity can be obtained simultaneously.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of injection machine injection screw, comprise the screw body of outer surface distributing auger sheet, described screw body comprises feeding section, compression section and homogenizing zone successively, the flight of described compression section is helical gear sheet, and the two sides of described helical gear sheet are evenly equipped with some protruding blocks.
In a preferred embodiment of the present invention, the hand of spiral of the gear grooved on described helical gear sheet is contrary with the hand of spiral of described helical gear sheet.
In a preferred embodiment of the present invention, described protruding block conically.
In a preferred embodiment of the present invention, the height of described protruding block is 2-3mm.
In a preferred embodiment of the present invention, the length of described feeding section, compression section and homogenizing zone is than being 3:2:1.
The invention has the beneficial effects as follows: by the flight of compression section is designed to helical gear sheet, and the hand of spiral of gear grooved on helical gear sheet is contrary with the hand of spiral of helical gear sheet, and on the two sides of helical gear sheet uniform conical protruding block, it is made to form a kind of effect of rapid stirring, play and strengthen the melt mixing effect with plastifying fast, and improve melt plasticizing quality; The length of each section of appropriate design, can obtain the melt of low temperature homogeneous and stable extruding and high plasticizing capacity simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation in the preferred embodiment of a kind of injection machine injection screw one of the present invention;
In accompanying drawing, each mark is as follows: 1, feeding section, and 2, compression section, 3, homogenizing zone, 4, flight, 41, helical gear sheet, 5, protruding block.
Detailed description of the invention
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of injection machine injection screw, comprise the screw body of outer surface distributing auger sheet 4, described screw body comprise successively to feed in raw material for solid and carry feeding section 1, the compression section 2 of compacting and melting and plasticizing and homogenising the homogenizing zone 3 of metering further, the flight of described compression section 2 is helical gear sheet 41, and the two sides of described helical gear sheet 41 are evenly equipped with some protruding blocks 5.
The hand of spiral of the gear grooved on described helical gear sheet 41 is contrary with the hand of spiral of described helical gear sheet 41; In rotary course, described helical gear sheet 41 acts on plastic cement, forms a kind of effect of stirring, makes raw material fully and mixing fast, and the plastic cement of molten state is plastified fast.
Conically, and the height of described protruding block 5 is 2-3mm to described protruding block 5; Play equally and strengthen the melt mixing effect with plastifying fast.
The length of described feeding section, compression section and homogenizing zone is than being 3:2:1; The melt of low temperature homogeneous and stable extruding and high plasticizing capacity can be obtained.
Present invention is disclosed a kind of injection machine injection screw, by the flight of compression section is designed to helical gear sheet, and the hand of spiral of gear grooved on helical gear sheet is contrary with the hand of spiral of helical gear sheet, and on the two sides of helical gear sheet uniform conical protruding block, it is made to form a kind of effect of rapid stirring, play and strengthen the melt mixing effect with plastifying fast, and improve melt plasticizing quality; The length of each section of appropriate design, can obtain the melt of low temperature homogeneous and stable extruding and high plasticizing capacity simultaneously.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and Figure of description content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
