In addition, the processing cycle of integral molds is long, the cost is high, and maintenance and updating are difficult.

[0003] With the continuous increase in the market demand for FRP products, the demand for FRP molds has also increased accordingly. The emergence of split molds provides a new solution for the production of FRP products and is expected to be widely used in the FRP field.

[0051] Specifically, the split mold for processing the flow guiding cover includes a split mold body and a split support skeleton for supporting and fixing the split mold body. The split mold body includes a left mold body 1 and a right mold body 2, and the left mold body and the right mold body are assembled and sealed through a vertical flange 3 provided at the bottom end of their outer surfaces; the split support skeleton includes a left mold skeleton 4 and a right mold skeleton 5, and the left mold skeleton and the right mold skeleton are assembled through a locking skeleton connection bracket 6; the suction areas of the left and right mold bodies are rigidly connected to the left and right mold skeletons respectively, and the product areas of the left and right mold bodies are flexibly connected to the left and right mold skeletons respectively.

[0052] The splicing seam at the inner surface of the left mold body and the right mold body is sealed and leveled with sealant to achieve the flatness of the inner surface after the split mold is assembled.

[0053] The above rigid connection is adhesive fixation, and the flexible connection is that a soft material is used as a filler pad to support between the split support skeleton and the split mold body.

[0054] The above-mentioned locking skeleton connection bracket includes a first connection column 601 and a second connection column 602 respectively connected to the left and right die skeletons. A positioning connection plate 603 is arranged at the outer end of each connection column, and a locking bolt 604 is arranged on the positioning connection plate; a guiding groove 605 is arranged in the middle of the first connection column, and a guiding column 606 is arranged in the middle of the positioning connection plate at the outer end of the second connection column. The guiding column corresponds to and is adapted to the guiding groove.

[0055] To ensure the flexibility of the assembly and use of the split die, a roller 7 with a wheel brake is arranged at the bottom end of the split support skeleton.

[0056] The above-mentioned left die body 1 includes a first arc panel 101 and a first bending plate 102, a second bending plate 103, and a third bending plate 104 continuously arranged along the outer periphery of the first arc panel. The two ends of the second bending plate are smoothly transitioned with the arc surfaces of the first and third bending plates respectively.

[0058] The above-mentioned first, second, third, sixth, seventh, and eighth bending plates form the suction cup areas of the left and right die bodies; the first and second arc panels form the product areas of the left and right die bodies; a first square convex surface 105 and a second square convex surface 205 are symmetrically arranged on the first arc panel and the second arc panel. The first square convex surface is arranged close to the second bending plate and the third bending plate, and the second square convex surface is arranged close to the seventh bending plate and the eighth bending plate.

[0059] The first, fourth, and fifth bending plates are bent upwards to be higher than the outer edge of the first arc panel they are connected to; the sixth and seventh bending plates are bent upwards to be higher than the outer edge of the second arc panel they are connected to; the third and eighth bending plates are bent downwards to be lower than the outer edges of the first arc panel and the second arc panel they are respectively connected to.

[0060] The first arc panel 101 and the second arc panel 201 are assembled to form arc surface structures with two different radian; the radian of the arc surface formed at the front part of the split mold body is smaller than that of the arc surface at the rear part of the split mold body. The arc surface located at the front part of the split mold body is arranged to gradually expand from the outer edge of the right-to-left arc surface towards the rear part of the split mold body.

[0061] A number of locking parts are arranged at intervals along the length direction of the vertical flange. The locking parts include a first locking part and a second locking part. The first locking part is a locking bolt 8 arranged at intervals along the length direction of the vertical flange. A reinforcing plate 9 is arranged on one side of the vertical flange between adjacent first locking parts. One side of the reinforcing plate is fixed to the vertical flange through the locking bolt. A plug bolt 10 is arranged on the vertical flange on the other side far from the reinforcing plate corresponding to the locking bolt. A guide sleeve 11 is arranged inside the two vertical flanges outside the plug bolt.

[0062] The above-mentioned left and right mold skeletons respectively include a bottom beam 12, a column 13 and a supporting top beam which are welded together. The supporting top beam is in shape matching with the outer surface of the left and right mold bodies; the supporting top beam includes a first supporting top beam 14 for supporting the left mold body and a second supporting top beam 15 for supporting the right mold body. The first supporting top beam includes a first outer peripheral top beam 141 which is rigidly connected to the suction cup area of the left mold body and a first inner connecting beam 142 arranged between the first outer peripheral top beams. The second supporting top beam 15 includes a second outer peripheral top beam 151 which is rigidly connected to the suction cup area of the right mold body and a second inner connecting beam 152 arranged between the second outer peripheral top beams; the first and second inner connecting beams are respectively in soft connection with the product area of the left mold body and the product area of the right mold body.

[0064] At the connection position between the suction cup area of the split mold body and the split supporting skeleton, the hard connection of the outer bottom surfaces of the first, second, third, sixth, seventh and eighth bending plates and the supporting top beam is realized by brushing clear resin and adhering felt strips for wrapping; the soft connection between the split supporting skeleton and the product area of the split mold body is realized by filling foam material between the product area of the split mold body and the inner connecting beam of the supporting top beam.

[0065] The aforementioned first connecting column 601 is arranged on the right column 13 of the left mold skeleton, and the second connecting column 602 is arranged on the column on the left side of the right mold skeleton. There are two first and second connecting columns on each column corresponding to each other up and down.

[0067] Furthermore, the reinforcing area formed by the reinforcing member realizes the permanent splicing of the outer surfaces of the assembly joints of the left and right mold bodies. The specific structural setting process of the reinforcing area is as follows: pre-brush a layer of mold hand-lay-up resin on the outer surface of the vertical flange at the assembly joint of the left and right mold bodies, then lay a first CSM300 chopped strand mat layer centered on the vertical flange and turn it to both sides by 50 mm each. After compressing and penetrating it with a roller to discharge air bubbles, then lay 4 layers of Combi1100 or 1250 and 1 layer of the second CSM300 chopped strand mat in sequence to form the layer structure of the reinforcing area. For each layer of fiberglass above, increase and stagger by 50 mm around the perimeter and compress and penetrate it with a roller to discharge air bubbles.

[0068] The assembly of the split mold for fairing processing is obtained by combining the made left and right mold bodies and then combining them with the split support skeleton. When assembling the two molds, first align and lock the guide columns of the skeleton connection bracket 6. After all the guide columns are assembled in place, pre-tighten the locking bolts of the skeleton connection bracket. Fix the vertical flanges of the two molds with quick clamps, check whether there is any misalignment of the gel coat on the inner surface of the mold. After checking the assembly status, loosen all the bolts and perform the final mold sealing treatment before the last assembly, that is, apply Sikaflex at the butting flanges of the two molds, and also apply Sikaflex to the reinforcing plates outside the vertical flanges for sealing. After tightening the bolt fasteners, apply Sikaflex to the inner surfaces of the two molds for sealing treatment.

[0069] The FRP fairing unit structure 20 is obtained by demolding after pasting with the split mold for fairing processing in the foregoing embodiment. The fairing unit structures are pairwise assembled and then connected at intervals to the circumferential direction of the fairing cone 18 of the FRP fairing to form the fairing body, and a connecting portion 19 is provided at the bottom of the spaced fairing unit structures to enclose the FRP fairing in this way. The spliced fairing body, fairing cone and connecting portion together enclose the FRP fairing with three circular holes evenly distributed in the circumferential direction. See Figure 10 Schematic.
