Description
Technical field
The present invention relates to a kind of online mixing Shooting Technique suitable for carbon fiber auto parts and components.
Background technology
With the development of auto industry, quality requirements more and more higher of the people to automobile.In order to adapt to development and the consumer demand in epoch, the world
The car manufactures of various regions are also innovated constantly, not only improve effect and quality of auto parts and components, and opposite produces the one of auto parts and components
A little frocks and production line are also carried out various improvement, cost-effective with improve production efficiency and reduction.Current automotive body structure part and half hitch component are also
It is metallic article, for the realization of automotive light weight technology, developed country replaces metal body structural member and half using new carbon fibre material in the world
Structural member, to reach automobile lightweight.
The carbon fiber component made using online mixing Shooting Technique has intensity high, and density is low, and dimensional stability is high, product quality stabilization, surface
The advantages of quality is high, is widely used to Aero-Space, military domain.Application of the carbon fiber component product on body of a motor car can be greatly reduced vehicle body
Weight, to improve fuel efficiency and reduce motor vehicle exhaust emission it is significant.
There are some thermoplastic composite moulding process such as GMT, LFT-D and LFT-G etc. in bumper, collision prevention girders, front end mould at present
Block, there is many applications on tyre-well, the weight saving ratio of single part or assembly is about 40-60%, to improving fuel efficiency and reducing car tail
Gas discharge is made that significant contribution.
But 3 kinds of techniques have certain limitation above.GMT and LFT-D mainly use mould pressing process.The GMT sheet stocks or LFT that will be heated
Group's material is put into mould, and matched moulds pressurization makes sheet stock or group's material obtain product full of cooling and solidifying after whole die cavity.Mould pressing process has certain limitation,
The complex part of unsuitable production shape and size.LFT-G is then to use Shooting Technique.Kneaded then during the pellet of LFT is added into injection machine
It is molded into mould, cooling and demolding is to obtain product.Shooting Technique is fairly simple, it is also possible to be molded complex structural member, but LFT-G techniques increased
The process of granulation, i.e., first could use fiber and plastic pellet after extruder kneads uniform and granulation together.And quadric injection mould can enter one
Step damages fiber, makes residual average fiber length in the product only 1-2mm or so.The performance of product is greatly reduced.
The content of the invention
To be solved by this invention to be, general thermoplastic composite moulding process automaticity is relatively low, and molding cycle is more long, general structure part
Time, the molding time of large product was even more than 2 hours at 30 minutes or so, this molding cycle can meet Aero-Space and other
The relatively low industry requirement of mass degree, but it is difficult to meet automobile industry on a large scale, the problem of mass production demand.
The technical scheme is that, a kind of online mixing Shooting Technique suitable for carbon fiber auto parts and components, realizing the equipment of the technique includes：
Double screw extruder, injection machine, automatic charging machine, pressure side feed system, die heater and cooling-water machine；It is characterized in that：Will be according to formulated resin
System is by automatic charging machine and forces side feed system to go out machine and kneaded and plastified plastic pellet, additive and filler addition dual-screw-stem machine；
The back segment of screw rod reclaims carbon fiber, go forward side by side one-step melting and plasticizing by forcing side feed system to add；Uniform plastics and carbon fiber are kneaded through too strong
The feeding valve of side feed system processed enters the injection cylinder of injection machine；Injection mold is closed by mode locking unit；The introduction valve of injection machine is opened, will be noted
Uniform plastics and carbon fiber are kneaded in the injection cylinder of molding machine by injection machine introduction valve injection moulding mould, while temperature is controlled using die heater,
Then simultaneously the demoulding is that can obtain semi-finished product to cooling-water machine cooling and solidifying；By semi-finished product by can obtain required product after the operations such as deburring.
Wherein, the feeding valve for forcing side feed system is closed while injection machine introduction valve is opened, uniform plastics is kneaded and carbon fiber mixture can be temporary
When storage in accumulator, realize effective combination of continuous mixing and discontinuous injection moulding process.
The beneficial effects of the invention are as follows using Shooting Technique, process is simple is ripe, plastic complex structural member；It is another heated without quadric injection mould
Journey, reduces a plasticizing operation, reduces the shearing force of plastics, reduces the fire damage of plastics；Only the back segment in screw rod heats carbon fiber, and
The screw rod of back segment is retained by substantially reducing shearing and chopping to carbon fiber, the carbon fiber length in product after transformation, improves the strong of product
Degree.GMT, the advantage of LFT-D and LFT-G techniques are inherited, and overcomes its shortcoming.
Brief description of the drawings
Fig. 1 is the online mixing Shooting Technique figure of carbon fiber auto parts and components of the present invention.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the present invention is realized are easy to understand, with reference to being specifically illustrating, enter one
Step illustrates the present invention.
