Description
Technical field
The utility model belongs to composite glass fiber reinforced plastics product field shaping technique, especially applies the glass fiber reinforced plastics product of RTM moulding.
Background technology
Tradition RTM formed glass steel part need to be used vacuum bag compacting, vacuum bag can not be able to not repeatedly utilize, or with causing product surface to occur that resin pocket or mould coordinate the problems such as finished product main body undercapacity that closely do not occur because mould is used die deformation for a long time in fiber reinforced plastic mold pressing process, existing preparation method is after formed product, to product polish, the patch work such as resin brushing, the dust that this kind of production method wasted a large amount of man-hours, material and polishing produce has a strong impact on operating environment, and is difficult to guarantee product quality.
Summary of the invention
The purpose of this utility model is to overcome the problems such as traditional RTM mould molding glass fiber reinforced plastics product surface resin alluvial, product strength deficiency and the polishing that causes, man-hour that patch work causes, material waste and because polishing produces the impact of a large amount of dust on working environment, and is difficult to guarantee the problems such as product quality.
The technical solution of the utility model is: a kind of RTM mould, comprise formpiston and former, formpiston is to take fiberglass as matrix, former is divided into former main body and edge, the two ends of former main body and symmetrical about former main body are located at edge, former main body is to take silica gel as matrix, and edge is to take fiberglass as matrix; Wherein the centre position at the two ends of formpiston is provided with alignment pin, on former edge, be provided with locating hole corresponding thereto, the edge of former and formpiston junction are provided with sealing joint strip, sealing joint strip has compressibility, in former main body, be provided with two through holes, be respectively bleeding point and gum-injecting port, bleeding point and gum-injecting port respectively all the corresponding seal cover that has it is sealed.
Further, described edge is L-type.
Further, being shaped as of described former main body is square, and identical with the finished form of injection moulding.
Further, described locating hole is located at the centre position at former edge.
Further, described sealing joint strip is fixed on former.
Further, described seal cover is quality of rubber materials.
Advantage and the good effect that the utlity model has are: the present invention adopts take silica gel and make the former of RTM mould as matrix, utilize the elasticity of silica gel matrix former own, make its in glass fiber reinforced plastics product production process because being subject to the effect of vacuum pressure to reach extruding glass, make glass compress and fit tightly with glass, solved the problems such as vacuum bag pressing glass steel moulding process vacuum bag film for a long time can not repeatedly utilize, the out-of-flatness of product inner surface and traditional RTM mould and coordinated the problems such as final resin alluvial, strength decreased that sternly do not cause.Simple to operate, with low cost, improved production efficiency, greatly improve working environment, and can reach problems such as improving product main body intensity elimination resin pocket.

The specific embodiment
The technical solution of the utility model is a kind of RTM mould, comprise formpiston 1 and former 2, as Figure 1-3, formpiston 1 is to take fiberglass as matrix, former 2 is divided into former main body 8 and edge 9, the two ends of former main body 8 are located at edge 9 and about former main body 8 symmetries, former main body 8 is to take silica gel as matrix, and edge 9 is to take fiberglass as matrix; Wherein the centre position at the two ends of formpiston 1 is provided with alignment pin 3, there is positioning function, on the edge 9 of former 2, be provided with locating hole 4 accordingly with formpiston 1, the edge of former 2 and formpiston 1 junction are provided with sealing joint strip 7, sealing joint strip 7 has compressibility, the cavity of junction and the space of body rim between sealing joint strip 7 sealing formpistons 1 and former 2 edges 9, in former 2 main bodys, be provided with two through holes, be respectively bleeding point 5 and gum-injecting port 6, bleeding point 5 and gum-injecting port 6 respectively all the corresponding seal cover that has it is sealed.
In the present embodiment, described edge 9 is L-type, and being shaped as of described former main body 8 is square, and identical with the finished form of injection moulding; Described locating hole 4 is located at the centre position at former edge 9; Described sealing joint strip 7 is fixed on former 2; Described seal cover is quality of rubber materials.
The course of work of this example is: first at RTM formpiston 1 mould gel coat face, evenly spray the thick product gel coat of 0.5mm; After solidifying, gel coat lays dimension glass fibre according to product laying; Former 2 is sling, and by the alignment pin 3 of formpiston 1, former 2 is placed on to formpiston 1 top; After having good positioning, connect former 2 bleeding points 5 to vavuum pump, and shutoff gum-injecting port 6, pressure pressurize taken out; Be subject to the former 2 of vacuum pressure silica gel material to make it be close to former 2 and formpiston 1 surface generation slight deformation extruded product glass, do not produce space cavity; After pressurize finishes, gum-injecting port 6 is connected in plastic holding device, the resin that stirs curing agent is pressed in RTM mould glass it; Injecting glue finishes rear shutoff bleeding point 5 and gum-injecting port 6, and after resin solidification, by former 2 demoulding from formpiston 2, formed product finishes.
RTM mould in the present embodiment is when glass fiber reinforced plastics product is produced, the special RTM former 2 that is matrix in order to silica gel with take the RTM formpiston 1 that fiberglass is matrix and coordinate, by the pressure of vacuum action, automatically make former 2 and product glass fit tightly, to realize the assurance of product strength and the elimination of resin pocket.
From said process, realized fitting tightly of mould and product, eliminated the problem of product surface resin pocket, simple to operate, with low cost, improve greatly intensity and the presentation quality of product.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
