Technical Field

[0001] The present invention belongs to the production equipment of composite materials, and particularly relates to an automatic forming equipment for composite material cabin sections with complex cross-sections. Background Art

[0002] Low-cost liquid molding processes for composite materials (such as RTM, VARI, etc.) have been widely used in various technical fields of composite materials and are gradually developing from the production of secondary load-bearing structural components to primary load-bearing structural components. Traditional RTM equipment is generally independent and separate from product molds, vacuum systems, etc. And for the RTM mold of composite material cabin sections, problems such as sealing are involved. The mold generally uses a large number of fastening screws for tightening and sealing. The mold is heated and injected with glue in an oven, with a slow heating rate and a poor injection environment, resulting in very low mold loading and demolding efficiency for cabin section products, and it is difficult to achieve continuous and automated production, thus affecting the large-scale production of products.

[0032] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions of the embodiments of the present invention with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0033] See Figure 1 As shown, an automatic forming device for a complex cross-section composite cabin section includes a first end plate 1, and is characterized in that: a plurality of wall plates 2 are vertically arranged on the first end plate 1, and the plurality of wall plates 2 enclose a cavity 3. The device further includes a male mold assembly 4 arranged in the middle of the cavity 3 and connected to the first end plate 1. A plurality of spacer blocks 20 are distributed on the inner wall of the wall plate 2, and a guiding space 21 is formed between adjacent spacer blocks 20. A female mold unit 50 is installed in each guiding space 21. A driving assembly 6 for driving the female mold unit 50 to move in the guiding space 21 is further arranged on the wall plate. All the female mold units 50 enclose to form a complete female mold assembly 5. A second end plate 7 is further arranged at the upper end of the wall plate 2, and the second end plate 7 is connected to the upper end of the female mold unit. A plurality of glue injection ports 10 are arranged on the first end plate 1, and a glue outlet 22 is arranged on the second end plate 7.

[0034] The present invention designs an automatic forming device for a complex cross-section composite cabin section. The space in the cavity is divided by spacer blocks to form a number of regular guiding spaces, thereby dividing the female mold. The divided female mold units can slide in the guiding spaces. All the female mold units enclose to form a complete female mold assembly. A mold cavity for accommodating the product is formed between the female mold assembly and the male mold assembly. The glue injection port and the glue outlet are communicated with the mold cavity. The present invention drives the female mold units to slide in the guiding spaces through the driving assembly, realizes the mold closing of the male mold and the female mold, and can maintain the position after the mold closing of the male mold and the female mold through the driving assembly, thereby ensuring the dimensional accuracy of the product. In addition, the automatic mold closing and demolding ensure the speed of each mold closing and demolding, overcome the problem of time-consuming manual mold closing and demolding in the prior art, greatly improve the production efficiency, and the automatic mold closing and demolding ensure the consistency of the mold closing and demolding accuracy, overcome the problem of poor consistency that may exist in manual operation in the prior art, and also ensure the consistency of the product, which is suitable for large-scale production of products.

[0035] Further, see Figure 3 and Figure 4As shown, a guide rail 210 is provided on the surface of the corresponding first end plate of each of the guiding spaces. A guiding groove 501 that mates with the guide rail is provided on the female mold unit 50. Under normal circumstances, the side wall of the female mold unit fits against the wall surface of the guiding space, thereby achieving the guiding of the female mold unit. In order to further improve the precision of the movement of the female mold unit and better ensure the precision when the female mold unit is closed to form the female mold assembly, the guide rail and the guiding groove are provided.

[0036] See Figures 5 to 8 As shown, the male mold assembly 4 includes a core mold support frame 40 connected to the first end plate. A plurality of male mold units 41 are fixed to the outside of the core mold support frame 40 by fasteners. The male mold units 41 enclose to form a complete male mold. In this embodiment, the male mold assembly adopts a split structure design of the core mold support frame and the male mold units. The core mold support frame is fixed and positioned with the first end plate, and the male mold units can be disassembled, which is convenient for subsequent demolding operations.

[0037] The core mold support frame 40 includes a support frame bottom frame 401, a bottom fixing block 402 integrally formed with the support frame bottom frame, and a support frame top frame 403. A plurality of connecting rods 404 are provided between the support frame bottom frame 401 and the support frame top frame 403. The male mold units 41 are connected to the connecting rods by fasteners. An accommodation hole 11 for accommodating the bottom fixing block is provided on the first end plate 1. In this embodiment, the structure of the core mold support frame is defined, adopting a structure design of upper and lower end frames and intermediate connecting rods. The male mold units are connected to the outside of the core mold support frame, which is convenient for removing the entire male mold unit from the inside, making the demolding operation more convenient, reducing the possible impact on the components during the demolding process, and ensuring the quality of the product.

[0038] An anti-misalignment hole 4020 is provided on the lower surface of the bottom fixing block 402, and an anti-misalignment block 110 that mates with the anti-misalignment hole is provided on the bottom surface of the accommodation hole 11. Since the cross-section of the cabin section is complex and asymmetric, if the female mold and the male mold are assembled incorrectly, it may cause damage to the mold. Therefore, the installation direction of the male mold assembly is ensured through the cooperation of the anti-misalignment hole and the anti-misalignment block, thereby avoiding the problem of mold damage caused by incorrect installation of the male mold assembly.

[0039] Furthermore, the bottom frame 401 of the support frame includes a first frame rod 4010. The two ends of the first frame rod 4010 are respectively connected to a second frame rod 4011 and a third frame rod 4012 through acute-angle transitions. A circular arc portion is provided for transition between the second frame rod 4011 and the third frame rod 4012. The first frame rod, the second frame rod, and the third frame rod enclose a space. The bottom fixing block 402 is located within this space and is respectively connected to the first frame rod 4010, the second frame rod 4011, and the third frame rod. The top frame 403 of the support frame is a circular frame body. Here, the shapes of the bottom frame and the top frame of the support frame are defined. Since the shape of the cabin section is a variable cross-section body that transitions from a triangle to a circle, the above-mentioned bottom frame and top frame of the support frame can better match the shape of the male mold.

[0040] Furthermore, positioning convex ribs 410 are provided on the lower end surface of each male mold unit 41, and positioning grooves 12 that cooperate with the positioning convex ribs are provided on the first end plate 1. The provided positioning convex ribs and positioning grooves, on the one hand, the cooperation between the positioning convex ribs and the positioning grooves can check whether the installation of the male mold assembly is correct and avoid the problem of incorrect installation of the male mold assembly. On the other hand, the cooperation between the positioning grooves and the positioning convex ribs can provide a supporting force to ensure the reliability of the male mold positioning during the injection molding process and prevent the problem of large product size errors caused by the displacement of the male mold.

[0041] See Figure 4 As shown, limiting convex ribs 411 are provided on the upper end surface of each male mold unit 41. A through hole 70 is provided on the second end plate 7, and a limiting ring 71 is formed on the second end plate at the lower edge of the through hole 70. The inner side surface of the limiting convex rib 411 abuts against the outer side surface of the limiting ring 71. In this embodiment, the cooperation between the limiting convex rib and the limiting ring is used to limit and support the upper end of the male mold to ensure the reliability of the male mold positioning during the injection molding process and prevent the problem of large product size errors caused by the displacement of the male mold.

[0042] See Figure 4As shown, an oil pipeline 502 is provided in each female mold unit 50, and a sliding hole 23 is provided on the wall plate 2. The oil supply pipeline 24 connected to the oil pipeline is installed in the sliding hole. Here, the structure of the female mold unit is improved. The oil pipeline provided in each female mold unit can control the mold temperature of the female mold unit by adding heat-conducting media at different temperatures into the oil pipeline, so that the entire automatic molding equipment can be used in a normal temperature environment, overcoming the problems in the prior art that the whole mold is placed in an oven for heating, with a harsh use environment and inability to be quickly reused multiple times. This enables the automatic molding equipment to continuously and stably produce in large quantities, effectively improving the production efficiency of products. Before injecting glue, the female mold and male mold can be heated by hot heat-conducting media to quickly reach the temperature required for injecting glue. After the injection of glue is completed, after the specified curing time, the mold temperature can be quickly reduced by cold heat-conducting media, shortening the time required to wait for the mold to cool.

[0043] In summary, the present invention has the following beneficial effects:

[0044] 1. The present invention designs an automatic molding equipment, which drives the mold closing of the female mold unit through a driving component, and ensures the dimensional accuracy between the female mold and the male mold through the driving component after the mold closing is completed, thereby ensuring the dimensional accuracy of the product. The present invention realizes the automation of the mold closing of the female mold and the male mold, greatly shortening the time required for manual assembly of the mold, improving the production efficiency, reducing the labor intensity of the staff, and at the same time, the demolding function can also be carried out through the driving component.

[0045] 2. The present invention is provided with an oil pipeline in the female mold, and the mold temperature can be controlled by hot oil or cold oil, more precisely controlling the mold temperature, overcoming the problems in the prior art that the mold heats up slowly and has uneven temperature, ensuring the fluidity of the epoxy resin during glue injection, and thus obtaining products with more stable product quality. At the same time, the automatic molding equipment of the present invention does not need to be placed in an oven, reducing equipment investment and also improving the production efficiency.
