Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.The present invention being usually described and illustrated herein in the accompanying drawings is implemented
The component of example can be arranged and be designed with a variety of different configurations.
Therefore, the detailed description of the embodiment of the present invention provided in the accompanying drawings is not intended to limit below claimed
The scope of the present invention, but be merely representative of selected embodiment of the invention.Based on the embodiments of the present invention, this field is common
Technical staff's every other embodiment obtained without creative efforts belongs to the model that the present invention protects
It encloses.
In the description of the present invention, it is to be understood that, the orientation or positional relationship of the instructions such as term " on ", "lower" is base
In orientation or positional relationship shown in the drawings or product of the present invention using when the orientation or positional relationship usually put, or
Person is the orientation or positional relationship that those skilled in the art usually understand, is merely for convenience of description of the present invention and simplification of the description,
Rather than the equipment or element of indication or suggestion meaning must have a particular orientation, is constructed and operated in a specific orientation, because
This is not considered as limiting the invention.
" first " of the invention, " second " etc., are only used to distinguish between description, have no special meaning.
In the description of the present invention, it is also necessary to which explanation is unless specifically defined or limited otherwise, term " setting ",
" installation " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or be integrally connected；It can be
It is connected directly, it can also be indirectly connected through an intermediary.It for the ordinary skill in the art, can be with concrete condition
Understand the concrete meaning of above-mentioned term in the present invention.
Due to RTM and lightweight RTM forming technique can not only make product it is two-sided it is smooth, surface quality is good, product size is smart
Degree is controllable, and has higher fiber volume fraction and mechanical property.Therefore, this two technologies are by favor.RTM forms work
The resin of liquid usually (is injected into mould inside under 3bar to 10bar), be heating and curing molding in elevated pressures by skill.In order to protect
Batch quality and the surface quality for demonstrate,proving product are controllable, must be requested that resin can be accurate in the temperature, pressure and flow of injection stage
Quantitative control.
Current RTM injection device both domestic and external is frequently with power such as compressed air pneumatic actuation mode, hydraulic drive pistons
Mode is injected.Pneumatic actuation mode refers to that (usual 3bar to 7bar) pushes resin to infuse into mold using compressed air
It penetrates.Pneumatic actuation mode has the following deficiencies: first, and pneumatic power source fluctuation is larger, and pressure is difficult stability contorting, if to solve
Certainly gas source problem needs to increase the complexity and land occupation volume of whole equipment using high-power compressor and pressure surge tank.
Second, because the compressibility of gas is larger, pressure feedback delay is larger, and response speed is low, is difficult accurately according to pressure in real time
Power adjusts the liquid pressure value injected in mold.Third, compressed air can introduce empty when pushing resin injection in resin
Gas causes defect to influence the mechanical property and apparent mass of product, and the flow of resin injection is also difficult accurate measurement
And control.Therefore, resin injection flow and essence all cannot effectively be measured using the equipment of such power type both at home and abroad at present
Really control injection speed.
It is more stable using the opposite starting driving of the power source of hydraulic driving mode, it can accurate control resin injection flow and note
Firing rate degree.But due to being controlled using hydraulic pressure unit, displacement sensor real time monitoring injection stroke need to be equipped with and calculate flow.In addition,
Hydraulic driving mode needs hydraulic oil, increases the weight and volume of equipment, is not easy to the carrying of equipment and flexibly uses.
Secondly, the cleaning of the injection tube of injection device is always a great problem, simultaneously by injection port suck-back cleaning agent at present
It is cleaned back and forth repeatedly, but often there are also a large amount of culls to need artificial cleaning, cleaning is complicated, extremely inconvenient.Finally, existing
Injection tube is generallyd use with upper cover in some equipment is bolted, and when installation need to consider each bolt pretightening to guarantee to have preferably
Air-tightness, after thinner silk thread mouth is stained with resin raw material, easy cleaning, air-tightness are not difficult to ensure.
In order to overcome drawbacks described above, present applicant proposes a kind of RTM injection devices, and small in size, light weight is easy to remove,
Flexibility in use is high.Meanwhile can be effectively controlled injection flow and injection speed, plastic injection quality it is good.Also, it is also convenient for injection
The cleaning of cylinder, cleaning is simple, and cleaning efficiency is high.
