Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing:
It is as shown in Figures 1 to 4:
A kind of cassette height is kneaded screw in injection molding machine, including ontology 1 and is connected to the screw head 2 of body front end, feature
It is: is connected with check ring 3 on the screw head 2, the roofbolt periphery of the screw head 2 is provided with the card wing 21 of protrusion, described
The card wing 21 is fastened on inside check ring 3.
The outer wall of the card wing 21 is provided with the fixture block 22 of protrusion, is provided on the ring wall of check ring 3 and matches with fixture block 22
The bayonet 31 of conjunction.
The front end of the card wing 21 tilts down setting along feedstock direction.
The ontology 1 is disposed with feed zone 11, plasticizing mask segments 12 and mixing section 13 along feedstock direction.
The feed zone 11 is provided with the feed well 111 of single thread formation.
It is blind that the plasticizing mask segments 12 are equipped with the feed auger that multiple groups are surrounded by auxiliary screw thread 124 and main thread 122 respectively
Slot 121 and discharging spiral blind slot 123, pass through main thread 122 between every group of feed auger blind slot 121 and discharging spiral blind slot 123
Separate, and the entrance of feed auger blind slot 121 is connected with feed well 111, the outlet and 13 phase of mixing section of the spiral blind slot 123 that discharges
Even, the outer diameter of main thread 122 is less than the outer diameter of auxiliary screw thread 124.
The mixing section 13 is equipped with parallel double wedge 131.
The working process and principle of the use of the new type are as follows:
Material enters the feed zone 11 of screw rod from hopper, under screw speed effect, is gradually pushed to screw head 2 and is pressed
It is real, while gradually melting enters plasticizing mask segments 12 under the shearing of screw rod and barrel and external heater effect.
In plasticizing mask segments 12, on the one hand main thread 122 stops a certain size solid phase to pass through, it is made to stay in feed auger
The shearing, extruding or heating by screw thread are continued on through in blind slot 121, promote to melt；Another party to cross the material of main thread 122 into
The stronger shearing of row, material, which is got back, further to be melted or is plasticized；The material of main thread 122 is crossed in discharging spiral blind slot
Generate eddy motion in 123, material is got back mixing.These, which are sheared and mix, is changed into thermal energy for mechanical energy, thus stiffener
The melting of material is homogenized.When material flows through main thread 122, each interlayer of stream have biggish speed difference, generate interlayer slip and
Frictional heat is generated, thus promotes the plasticizing of material；For material when entering feed auger blind slot 121, material is by band-like laminar flow quilt
If being divided into carried interest, when outflow discharges spiral blind slot 123, if material is merged together by carried interest, such stream is also easy to produce whirlpool
Stream generates direction change, the redistribution mixing of each section material of stream, is conducive to the dispersion of additive and color masterbatch.
In mixing section 13, double wedge 131 smashes solid material, destroys melt, upsets the two-phase flow of solid and liquid, and
Stream is repeatedly separated, direction and VELOCITY DISTRIBUTION of the stream between barrel and screw rod are changed, keeps solid phase and liquid phase sufficiently mixed
It closes, increases the heat transfer area between solid phase and liquid phase, and certain resistance and fricting shearing are generated to material, make solid phase fusion；It is convex
Tooth 131 by material carry out repeated segmentation, shunting and increase the dispersibility of mixing, homogenizing and additive to material, color masterbatch.
During the motion, check ring 3 rotates jointly under the action of the card wing 21, fixture block 22 with screw rod screw rod, and the two is not
There are relative motions, almost without friction between check ring 3 and screw rod, largely reduce the abrasion of check ring 3, increase
The service life of check ring 3.
The description of the embodiments and the specification only illustrate the principle of the present utility model and most preferred embodiment, is not taking off
Under the premise of from the spirit and scope of the utility model, the utility model also has various changes and improvements, these changes and improvements
It falls within the scope of the claimed invention.
