Property, using carbon fiber make component quality is light, specific stiffness is high, have wide range of applications.But carbon fiber mature at present
There are mainly four types of application forms, and one kind is that hand pastes pressurized layer method, and the carbon fiber sheet after dipped glue is cultrated lamination or one side laying
Resin is painted on one side, and reheating is molded, and carbon fiber product intensity made of this kind of method is high, but production efficiency is low；One kind is
Carbon mono-filaments are wrapped in carbon fiber axle by filament winding process, and such method is only applicable to production cylindrical body and holloware,
And production efficiency is low；One kind is die pressing, and this method is that the carbon fibre material of pre-soaked resin is put into metal die,
It overflows extra glue after pressurization to come, then hot setting forms, and carbon fiber product intensity made of this kind of method is high, but same
Sample production efficiency is low, and can not make structural member；For long fine pellet injection moulding pellet is made in carbon fiber preprocessing by one kind,
Again via injection molding machine injection molding, although such method solves production efficiency problem, but fibre length is longer in pellet
Carbon fiber, under the shearing and heat effect by screw in injection molding machine and hot flow path, in manufactured goods fibre length 5mm or more only
It is 30%, manufactured goods intensity is caused to substantially reduce.
Since the intensity of carbon fibre material itself predisposes to damage at high temperature, and the length of carbon fiber and its in manufactured goods
In staggeredly complexity, will affect the intensity of its manufactured goods, it can be seen that, it is in sight to guarantee at present for the application of carbon fiber
Carbon fibre material intensity realizes that the production technology of large-scale industrial production is vacancy again, for realizing the serialization of carbon fiber
The equipment of production and processing and forming is similarly in the state of the market vacancy, and therefore, carbon fiber can be reduced by height by developing one kind
The time of temperature damage is capable of increasing length of the carbon fiber in manufactured goods again, and the efficiency for being able to satisfy industrial mass production needs
The equipment asked is particularly necessary.
And in the prior art, a feed inlet is arranged in the compounding structure majority of injection molding machine, and it is right under different process not to be able to satisfy
Material to be processed uses the different heating time, and the demand of different heating temperature is smaller to the applicability of operating condition.
In view of the above drawbacks, creator of the present invention obtains the present invention by prolonged research and practice finally.
Summary of the invention
To solve above-mentioned technological deficiency, the technical solution adopted by the present invention is, provides a kind of compounding structure, including compounding

Cylinder；
The cylinder assembly includes: opening cylinder and silent cylinder, and through-hole, the through-hole are provided on the opening cylinder
For material to be processed to be put into the compounding structure；The silent entire body is used to constitute the screw rod cylinder；
According to process requirement, the through-hole is the location of on the screw rod cylinder, by the opening cylinder and described
The combination of silent cylinder determines.
Preferably, the material to be processed includes continuous fiber and formula materials；Number of openings on the opening cylinder
At least 2, the through-hole includes: fiber feed through-hole and particulate charge through-hole,
The fiber feed through-hole, is used to put into the continuous fiber；
The particulate charge through-hole, is used to put into the formula materials.
Preferably, the screw rod inner barrel is equipped with screw arbor assembly, the screw arbor assembly is arranged side by side by least two
Screw rod is constituted, and for shearing material to be processed, and threadingly, direction of advance conveys the material to be processed to the screw arbor assembly
To downstream.
Preferably, fiber feed through-hole described in wherein at least one is located at the downstream position of the particulate charge through-hole.
Preferably, the cylinder assembly further includes silent cylinder, the opening cylinder that is used to arrange in pairs or groups constitutes the screw rod
Cylinder.
Preferably, the compounding structural outer is also connected at least side drawing-in device, feed intake for realizing side, it is described
Through-hole corresponding with the side drawing-in device is additionally provided on screw rod cylinder.
Preferably, the side drawing-in device includes side feeding feed inlet, it is used for the material investment to be processed institute
State side drawing-in device.
Preferably, the side drawing-in device includes side feeding compounding devices, it is used to throw the side feed material feed inlet
The material to be processed entered is sheared, is melted.
Preferably, being disposed at least one heating device on the screw rod cylinder, it is used to add the material to be processed
Heat fusing.
A kind of injection-moulding device comprising: transformational structure and a multi-stage injection structure are penetrated in a storage, which is characterized in that the note
Moulding equipment further includes compounding structure as described above.
Compared with the prior art the beneficial effects of the present invention are: 1, pass through the opening cylinder and the silent cylinder
Collocation installation, to realize the change to the lead to the hole site and the variation of barrel lenght, and then when meeting actual production into
The different situation of discharge position demand keeps the cylinder setting form more diversified, meets the needs of kinds of processes production.2, root
It adjusts the through-hole by way of the opening cylinder and the own combination of the silent cylinder according to the specific needs of technique and exists
Position on the screw rod cylinder, so by change to the lead to the hole site and be arranged on the screw rod cylinder
Heating device cooperation, hold heating time and the heating temperature of the material to be processed, meet industrial diversification
Demand, avoid enterprise repeat to purchase accessory and caused by increased costs.3, by heating temperature, heating time, there are larger differences
Different types of formula materials are processed respectively, after its melting, then are compounded, meet the diversification under complicated technology
Production requirement, avoid because different materials and meanwhile shear, simultaneously heating melting, the processing performance of product structure, product is caused
Loss.4, the continuous fiber and the formula materials are separately put into the compounding structure, and the throwing of the continuous fiber
Enter the downstream that position is located at the investment position of the formula materials, the shearing to the continuous fiber and heating time can be reduced,
To keep the fiber fragment length of the formation after the continuous fiber shearing longer, the fiber segment accounting greater than 5mm is more, into
And make finished parts formed after injection molding in tensile strength and impact strength, compared with continuous fiber heating and shear time
Long production method has bigger promotion.
