Abstract
The invention discloses an RTM forming feeding device comprising a forming material and a mold used for sealing the forming material. The forming feeding device further comprises a T-shaped connector. A discharge port of the T-shaped connector communicates with a feed port of the mold. A glue injection opening of the T-shaped connector is used for communicating with an injection gun. A plug capable of moving up and down in the T-shaped connector is arranged in a glue blocking opening of the T-shaped connector. The RTM forming feeding device has the beneficial effects that the plug and the T-shaped connector are matched, it is ensured that no bubbles can enter the mold, it is also ensured that resin and fiber cloth are sufficiently wetted, and the T-shaped connector is convenient to clean.
Description
Technical field
The invention belongs to field of compound material.
Background technology
Rtm molding is in clamp mould, laying by design requirement calculated fibre reinforced materials preformation in hard
Type body, by die sealing, and reserves well into and out of material mouth, adopts injection device by resin from charging aperture in the range of certain pressure
In injection closed mould cavity, allow resin fully to infiltrate the packing materials such as the fiber of the inside, more successively discharging opening is blocked, extract rifle
Head, blocks charging aperture (have at charging aperture and ooze out resin fluid-tight, prevent from extracting bubble during pipette tips and be mixed into), and mold closing solidifies, and height is obtained
A kind of moulding process of performance composite.
But if it is used for molding long rectangular dimension product, design is entered fashionable from upper surface material feeding, it is understood that there may be product cannot
Complete wetting, when easily dead angle, needs from bottom feed, and " yi word pattern " charging aperture pipeline now, is usually used,
After extracting pipette tips at charging aperture, at charging aperture, there is no fluid-tight resin, after drawing guns with insertion plug before aperture time in, tree
Fat will flow out rapidly from charging aperture, and air is scurried into rapidly in product, causes to be mixed into bubble in product, affects product quality.
Joint is planted using Fig. 1, pulls out pipette tips after the completion of injecting glue and arrive the gap blocking joint with plug again, air can be rapid
Generation bubble in mould is scurried into by joint, has a strong impact on the quality of product；If using the u-shaped joint of second Fig. 2, in injecting glue
After the completion of plug can only block up (u-shaped joint corner) at a of u-shaped joint, can guarantee that resin is fully infiltrated with fillers such as fibers,
Stop bubble from penetrating into mould from joint, but the resin of joint remainder can not be cleared up in time, has a strong impact on u-shaped
The reuse (see attached Fig. 1 and 2) of joint.
Content of the invention
In order to overcome the problems referred to above, the invention provides a kind of avoid bubble to enter material, the resin of joint remainder
But the rtm material injector for forming cleared up can be obtained in time.
The technical scheme is that
Rtm molding feed arrangement, the mould including processing materials with for sealing processing materials, molding feed arrangement also has one
Individual t type joint, the discharging opening of t type joint is connected with the charging aperture of mould, and the gum-injecting port of t type joint is used for and filling gun phase
Connection, the stifled Jiao Kou of t type joint is provided with the plug that can move up and down in t type joint.
Further, the driving means of above-mentioned plug are hydraulic pressure or jack.
Further, above-mentioned plug is provided with stopping means, and stopping means make the top of plug be less than material interface.
Further, above-mentioned filling gun is provided with stopping means, and the shower nozzle of filling gun must not exceed injecting glue interface.
The beneficial fruit of the present invention is: plug is matched with t type joint, has both ensured that not having bubble enters mould, also ensures
Resin is fully infiltrated with fiber cloth, and, the also convenient cleaning of this t type joint.

Specific embodiment
The present invention is further illustrated below in conjunction with the accompanying drawings:
In the present invention, the noun of locality of use typically refers to the upper and lower, left and right shown in refer to the attached drawing as " upper and lower, left and right "；
" inside and outside " refers to inside and outside with respect to each part profile of itself.
Shenfu Fig. 3, processing materials 1 are placed in the mould 2 of sealing, and mould 2 bottom is provided with enters item for injecting glue；Charging
When, from gum-injecting port 3 resin by injection glue, gum-injecting port 3 length of t type joint 4 should be rationally it is ensured that pipette tips will not extend into filling gun
Injecting glue interface 9 (gum-injecting port root), stifled glue mouth 5 is blocked with plug 6.
During injecting glue, plug 6 built-in length not can exceed that stifled glue interface 10, after material feeding infiltration fully, by going out of t type joint 4
Material mouth is blocked up in fact, then promotes plug 6 to material interface 8(charging aperture and mould junction with jack 7), allow mould 2 to be formed
Sealing system, at this moment, pulls out injection pipette tips, can be prevented effectively from because bottom resin flows out and cause the situation that bubble pours in mould to send out
Raw.
Meanwhile, after pulling out pipette tips, stifled glue mouth 5 direction of t type joint 4 (i.e. stifled glue interface 10 is arrived at material interface 9) by
Plug 5 filling is full, and gum-injecting port 3 direction cull can voluntarily flow out, inside t type joint 4 will not cull, Bu Huizao
The situation of the follow-up demoulding is affected after resin solidification.
The beneficial effect of this patent is, t type joint 4 goes for feeding from mould bottom, and can be prevented effectively from and pull out
During filling gun, bubble pours in mould.
Specifically, t type joint is matched with plug, and rtm injector is connected with gum-injecting port, and during injecting glue, injection muzzle passes through
Resin adhesive liquid is sent in mould by gum-injecting port, and injection pipette tips built-in length must not exceed injecting glue interface, and now, plug blocks joint
Part (part below stifled glue interface in Fig. 3) below gum-injecting port, after glue with the abundant infiltrations such as fiber cloth, uses jack
Promote plug, block the part (plug blocks up joint material interface) of more than the gum-injecting port of t type joint, allow mould to be formed close
Envelope system, then pulls out injector gun barrel, waits product solidification.
As the another kind deformation of the present invention, plug 6 can also driving otherwise, such as hydraulic means.
Stopping means can also be provided with, such as limited block, banking pin etc., in order to prevent plug from crossing material circle on its plug
Face.
In the same manner, filling gun can also be provided with stopping means, such as limited block, banking pin etc., in order to prevent plug from crossing injecting glue
Interface.
Describe the preferred embodiment of the present invention above in association with accompanying drawing in detail, but, the present invention is not limited to above-mentioned reality
Apply the detail in mode, in the range of the technology design of the present invention, multiple letters can be carried out to technical scheme
Monotropic type, these simple variant belong to protection scope of the present invention.
