Further, heating mould ontology to set temperature and is kept the temperature.
Using after above scheme compared with prior art, the invention has the following advantages that can control each resin flow channel is
The no resin flow for having resin to pass through and pass through can avoid resin overflow by providing holes path control valve, and after controlling dipping
Fiber aperture, when replacing different types of fiber, can by replacement pore size control valve come guarantee fiber pass in and out mold when
Flash phenomena does not occur, can be carried out closing according to different production scales and open different number runner, to realize resin pressure
Controllably, number of fiber is adjustable, fiber impregnation front and back aperture is adjustable；Resin pressure is controllable, can effectively control the fiber in product
Content；Number of fiber is adjustable, and production scale can be effectively controlled；Aperture is adjustable before and after fiber impregnation, can effectively be applicable in different type
Fiber.
Detailed description of the invention:
Fig. 1 is the structural diagram of the present invention.
Specific embodiment:
With regard to specific embodiment, the invention will be further described with reference to the accompanying drawing:
As shown in Figure 1, a kind of fiber impregnation device, is used for fiber impregnation molten resin, including die ontology 1, mold sheet
It is equipped with N number of fiber channel 2 along die length direction in body 1, is also equipped with N number of resin stream along die width direction in die ontology 1
Road 3, resin flow channel 3 correspond one corresponding fiber channel of end connection so that each resin flow channel with fiber channel 2,
The entrance in resin fibre channel is correspondingly provided with the pore size control valve 4 in control fiber aperture, and resin flow channel 3 is equipped with control resin stream
The flow control valve 5 of amount, wherein N >=2, for convenience of explanation, N is 2 in the present embodiment,
It holds above-mentioned, further illustrates, resin flow channel 3 is arranged in a mutually vertical manner with fiber channel 2.For the fiber after control dipping
Aperture and avoid molten resin from fiber channel outlet overflows, after the outlet of fiber channel 2 is again provided with control impregnating resin
Fiber aperture pore size control valve 6.The section of fiber channel 2 can be circle, it is of course also possible to be other shapes, resin
Runner.
Hold above-mentioned, in order to control the effect and cost consideration of flow, flow control valve is to be arranged perpendicular to resin flow channel
And the screw of resin flow channel can be blocked from die ontology side precession die ontology and completely, the screw is when suitable with resin flow channel
Match, screw range is exactly the width of runner, and when using screw as flow control valve, resin flow channel is when selection circular cross-section.
In addition, pore size control valve is the hollow screw being spirally connected with fiber channel, the internal diameter of screw with wait enter fiber channel
Fiber outer diameter adaptation, the pore size control valve in corresponding aperture is matched according to different fibers.
Except this, the present invention also provides a kind of methods impregnated using fiber impregnation mold comprising following steps,
Step 1 chooses N root fiber, according to the entrance for requiring the pore size control valve for selecting adaptation and being mounted on fiber channel
And outlet, by fiber by sending volume equipment to be respectively fed in different fiber channels, and resin flow channel import and extruder are connected
It connects, passes through the resin of extruder input melting；
Step 2 makes to melt according to the flow for requiring control with conveying the resin flow channel for having the fiber channel of fiber to be connected to
