When carrying out composite RTM techniques using above-mentioned mould, its process is to comprise the following steps：
Step 1, cope plate 7 is lifted, die cavity height is adjusted by die cavity governor motion 8；
In the step 1, depth scale real-time detection die cavity height is placed in die cavity.Use the adjustment type of die cavity governor motion 8
Chamber height, such as needs die cavity highly to reduce, then sliding part 52 rises, first unscrews top nut, then tighten lower nut, pass through depth scale
Observation is reached after ideal height, tightens top nut, and peripheral type chamber governor motion 8 is according to said method operated successively, die cavity is reached reason
Think height；Such as need die cavity highly to increase, then sliding part 52 declines, first unscrew lower nut, then tighten top nut, pass through depth scale
Observation is reached after ideal height, tightens lower nut, and peripheral type chamber governor motion 8 is according to said method operated successively, die cavity is reached reason
Think height；
Step 2, after die cavity is highly fixed, uniformly smeared with releasing agent inside the die cavity that cope plate 4 and lower template 5 are constituted,
PE pipes are inserted in pouring mouth device；
In the step 2, PE pipes are inserted in pouring nozzle, tightened with being respectively mounted pouring nozzle in plastic hole by hole for injecting glue respectively
Bushing, and then nylon ring deformation is extruded, play a part of sealing and banding PE pipes.The PE pipes connection RTM resin notes of injecting glue nose end
Penetrate machine, the PE pipes connection resin trap of plastic emitting nose end.
Step 3, the fiber cloth fabric after cutting is put into die cavity, and under pull handle, close cope plate, carry out matched moulds；
In the step, during matched moulds, cope plate is positioned by location nut, and after fastening bolt is tightened, tighten fastening spiral shell
Mother carries out mechanical fasteners.
Step 4, open resin injector and carry out resin-cast, and observation window, real-time monitored tree are used as by toughness reinforcing glass
Fat filling flowing, after after resin end-of-fill, closes resin injector；
Step 5, after the completion of injection, temperature control system is opened, it is uniform by heating cloth, elevated cure is carried out to resin；
Step 6, molded after the completion of resin solidification；
In the step, clamp nut is first turned on successively, fastening bolt is then turned on, air compressor is opened, and is opened pneumatic
Valve, air compressor provides die sinking power, promotes thimble in pneumatic jack to rise, cope plate is separated with lower template, lifting handle,
Composite panel material products are taken out after die sinking；
Step 7, mould is cleared up, composite panel material products are repaired.
From the above, it is seen that the present invention can produce dual light composite panel compared to above-mentioned traditional RTM mold
Material products；The thickness of die cavity is adjusted using screw mechanism, composite plate thickness range is made extensively with control, precision is high,
Can self-locking advantage；By rationally designing die-sinking device, advantage simple with die sinking, easy to operate；Design optimization mold filling stream
Road, is injected using surrounding, center discharge mode, is shortened mould-filling time, is reduced product defect, and then improve product matter
Amount；By designing primary seal circle and auxiliary seal ring, realize that mould sealing is tight；Made using polytetrafluoroethylene (PTFE) and pour mouthpiece, had
There is non-sticky resin；By apparatus for pouring reasonable in design, with cast good airproof performance, easy to operate function；Pass through
