Description
Technical Field
[0001] This invention relates to a molding die for a double-sided closed beam and a demolding method thereof. Background Technology
[0002] Beam-type components are common load-bearing structural parts in aircraft, playing a crucial role in aircraft flight. Their quality directly affects the aircraft's flight performance and safety performance.
[0003] Beam-type parts generally consist of a web and flanges, and their structures are typically C-shaped or I-shaped. C-shaped beams can be further classified into closed beams and open beams based on the angle between the flanges and the web. Due to the special nature of their structure, closed beams are mostly formed using a female mold. However, in certain specific situations, the mold needs to be designed as a male mold. But because of the closed angle, the mold structure and demolding method are generally more complex, and demolding is difficult. Those skilled in the art often forcibly remove the part by hammering or other means, causing internal and external problems and resulting in a high scrap rate. Therefore, this invention proposes a forming mold for double-sided closed beams and its demolding method to solve the above problems. Summary of the Invention

[0030] A demolding method for a molding die for a double-sided closed beam includes the following steps:
[0031] S1. Mold Design:
[0032] Based on the inner surface of the double-sided closed beam, the main structure is designed on the surface of the main mold body and the parting mold body respectively, so that the inner surface of the double-sided closed beam is precisely fitted onto the surface of the main mold body and the parting mold body;
[0033] S2, Mold Positioning:
[0034] After the mold design is completed in S1, align the main mold pin holes and the parting mold pin holes and insert the pins. At the same time, install bolts in the main mold mounting holes and the parting mold mounting holes to connect the main mold body and the parting mold body into a whole.
[0035] S3, Part Forming:
[0036] The double-sided closed beam parts are formed on the main mold body and the parting body as a whole in S2 and mold positioning;
[0037] S4, Auxiliary Limiter:
[0038] S3, the main mold body and the part forming body are placed on multiple sets of demolding auxiliary components, and the main mold body is limited.
[0039] S5, Mold body disconnection:
[0040] After S4 and auxiliary limiting are completed, the pins and bolts in S2 and mold positioning are disassembled until the main mold body is no longer connected to the mold parting body as a whole.
[0041] S6, Edge separation:
[0042] The ejector block is ejected from the ejector slot by bolting it into the threaded hole and rotating it continuously, so that there is a gap of 5mm-10mm between the flange strip on the double-sided closed beam part and the outer wall of the main mold body.
[0043] S7. Separation of the web plate:
[0044] Rotate multiple sets of rotating handles to make multiple sets of universal heads contact the top inner wall of the mold body through multiple sets of movable slots. After all contacts are made, rotate the rotating handles again to make the mold body slowly rise along the guide column axis, separating the web plate on the double-sided closed beam part from the main mold body.
[0045] S8. Part unloading:
[0046] Completely detach the double-sided closed beam parts from the parting body during the separation of S7 and the web plate, thus completing the demolding process of the double-sided closed beam parts.
[0047] Compared with the prior art, the beneficial effects of the present invention are:
[0048] During demolding, the main mold body and the parting body containing the double-sided closed beam part are placed on multiple sets of demolding auxiliary components. The demolding auxiliary components limit the main mold body. Then, the ejector block moves in a direction perpendicular to the side wall of the main mold body, causing the flange to separate from the side wall of the main mold body. Then, the ejector component lifts the parting body, causing the web of the double-sided closed beam part to rise and detach from the main mold body. Finally, the web of the double-sided closed beam part is separated from the parting body.
[0049] With the above-mentioned split design of the main mold body and the split mold body, when demolding the double-sided closed beam parts, different positions of the double-sided closed beam parts can be demolded separately. During the demolding process, there is no need to hammer the double-sided closed beam parts, which can effectively improve the quality of the double-sided closed beam parts, avoid damage to the double-sided closed beam parts caused by hammering, and effectively solve the problem of difficult demolding of double-sided closed beam parts.
[0050] With the aforementioned split design of the main mold body and the dividing mold body, the demolding efficiency of the double-sided closed beam parts can be effectively improved because no manual hammering is required. At the same time, it can also save manpower and facilitate mass production. Attached Figure Description

[0066] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0067] Example:
[0068] like Figure 1-14 As shown, this embodiment proposes a molding die for a double-sided closed beam, used for demolding the web 31 and flange 32 on part 30, including:
[0069] Main mold body 10; the side wall of the main mold body 10 is provided with a movable ejector block 191;
[0070] Partition body 20 is provided on the main mold body 10; used for forming web plate 31 and flange strip 32.
[0071] Multiple sets of demolding auxiliary components 40 are disposed below the main mold body 10 and the parting mold body 20; they are used to support the main mold body 10 and the parting mold body 20 and to limit the position of the main mold body 10.
[0072] Multiple sets of ejection components 50 are respectively set on multiple sets of demolding auxiliary components 40; used to lift the mold parting body 20 to increase its displacement for demolding.
[0073] The ejector block 191 is displaced in a direction perpendicular to the side wall of the main mold body 10, causing the edge strip 32 to separate from the side wall of the main mold body 10.
[0074] The upward displacement of the split mold body 20 causes the web plate 31 to separate from the main mold body 10.
[0075] In this embodiment, during production, the web 31 of the double-sided closed beam part is formed on the surface of the main mold body 10 and the parting mold body 20, and the two sets of flanges 32 of the double-sided closed beam part are formed on the sides of the main mold body 10 and the parting mold body 20 respectively.
[0076] During demolding, the main mold body 10 containing the double-sided closed beam part and the parting body 20 are placed on multiple sets of demolding auxiliary components 40, and the demolding auxiliary components 40 limit the main mold body 10. Then, the ejector block 191 moves in a direction perpendicular to the side wall of the main mold body 10, so that the flange 32 separates from the side wall of the main mold body 10. Then, the ejector component 50 lifts the parting body 20, so that the web plate 31 of the double-sided closed beam part is raised and detached from the main mold body 10. Then, the web plate 31 of the double-sided closed beam part is separated from the parting body 20.
[0077] With the split design of the main mold body 10 and the split mold body 20, when demolding the double-sided closed beam parts, different positions of the double-sided closed beam parts can be demolded separately. During the demolding process, there is no need to hammer the double-sided closed beam parts, which can effectively improve the quality of the double-sided closed beam parts, avoid damage to the double-sided closed beam parts caused by hammering, and effectively solve the problem of difficult demolding of double-sided closed beam parts.
[0078] With the split design of the main mold body 10 and the split mold body 20, the demolding efficiency can be effectively improved when the double-sided closed beam parts are demolded because no manual hammering is required. At the same time, it can also save manpower and facilitate mass production.
[0079] Specifically, the main mold body 10 is provided with a first inclined surface 13 and a second inclined surface 15. A main mold plane 12 is provided between the first inclined surface 13 and the second inclined surface 15. The first inclined surface 13 and the second inclined surface 15 are arranged in parallel. The first inclined surface 13, the second inclined surface 15, and the main mold plane 12 are combined to form a vertical stepped shape.
[0080] The mold-separating body 20 is provided with a first mold-separating inclined surface 26 and a second mold-separating inclined surface 27. A mold-separating plane 24 is provided between the first mold-separating inclined surface 26 and the second mold-separating inclined surface 27. The first mold-separating inclined surface 26 and the second mold-separating inclined surface 27 are arranged in parallel. The first mold-separating inclined surface 26, the second mold-separating inclined surface 27, and the mold-separating plane 24 are combined to form an inverted stepped shape.
[0081] The first inclined surface 13, the second inclined surface 15, and the plane 12 of the main mold are respectively matched with the first inclined surface 26, the second inclined surface 27, and the plane 24 of the parting mold.
[0082] In this embodiment, by matching the first inclined surface 13, the second inclined surface 15, and the plane 12 of the main mold with the first inclined surface 26, the second inclined surface 27, and the plane 24 of the parting mold respectively, it is easy to combine the main mold body 10 and the parting mold body 20 into a whole.
[0083] Of course, when the first inclined surface 13, the second inclined surface 15, and the plane 12 of the main mold are joined with the first inclined surface 26, the second inclined surface 27, and the plane 24 of the parting mold respectively, they form a "Z" shape. The angle between the parting line of the first inclined surface 13 and the second inclined surface 27 of the main mold and the web 31 is β, preferably β < α - 3°.
[0084] Specifically, a plurality of main mold pin holes 14 are provided through the first inclined surface 13 of the main mold, and a plurality of parting mold pin holes 25 are provided through the first inclined surface 26 of the parting mold.
[0085] The main mold pin hole 14 and the parting mold pin hole 25 are matched in position, and a pin is provided between the main mold pin hole 14 and the parting mold pin hole 25.
[0086] In this embodiment, by matching the positions of the main mold pin hole 14 and the parting mold pin hole 25, the main mold body 10 and the parting mold body 20 can be positioned by pins so that the main mold body 10 and the parting mold body 20 can form a whole, which facilitates the forming of double-sided closed beam parts on the main mold body 10 and the parting mold body 20.
[0087] Specifically, a plurality of main mold mounting holes 16 are provided through the second inclined surface 15 of the main mold, and a plurality of parting mold mounting holes 28 are provided through the second inclined surface 27 of the parting mold.
[0088] The main mold mounting hole 16 and the parting mold mounting hole 28 are matched in position, and bolts are provided between the main mold mounting hole 16 and the parting mold mounting hole 28.
[0089] In this embodiment, by matching the positions of the main mold mounting hole 16 and the parting mold mounting hole 28, the main mold body 10 and the parting mold body 20 can be connected by bolts to form an integral whole, so that the main mold body 10 and the parting mold body 20 can be formed as a whole, and the double-sided closed beam parts can be formed on the main mold body 10 and the parting mold body 20.
[0090] Specifically, two sets of guide posts 17 are provided on the main mold plane 12;
[0091] Two sets of guide grooves 22 are provided on the parting plane 24. The two sets of guide grooves 22 are respectively matched with the positions of two sets of guide posts 17. A guide sleeve 23 is provided in the guide groove 22 and the guide sleeve 23 is fitted on the outer wall of the guide post 17.
[0092] In this embodiment, by cooperating with the guide sleeve 23 and the guide post 17, when the mold part 20 is lifted, it can avoid the mold part 20 from interfering with the main mold body 10 and affecting the demolding efficiency of the double-sided closed beam parts. At the same time, it can also protect the main mold body 10 and the mold part 20.
[0093] Specifically, the outer wall of the main mold body 10 is provided with multiple sets of main mold ear plates 11;
[0094] The outer wall of the mold parting body 20 is provided with multiple mold parting ear plates 21. The main mold parting ear plate 11 is matched with the mold parting ear plate 21. The demolding auxiliary component 40 limits the main mold parting ear plate 11, so that the main mold body 10 is positioned on the demolding auxiliary component 40.
[0095] In this embodiment, when the main mold body 10 and the parting mold body 20 are limited on the demolding auxiliary component 40, the demolding auxiliary component 40 limits the main mold ear plate 11, thereby limiting the main mold body 10 and preventing the main mold body 10 from rising along with the parting mold body 20 when the parting mold body 20 is raised.
[0096] Of course, the main mold ear plate 11 and the parting mold ear plate 21 can also be used for hoisting, thereby driving the whole displacement onto the demolding auxiliary component 40.
[0097] Specifically, multiple sets of mounting blocks 18 are provided on the inner side wall of the main mold body 10 away from the mold splitting body 20, and the mounting blocks 18 are provided with threaded holes 181.
[0098] Multiple sets of ejector grooves 19 are provided on the outer side wall of the main mold body 10 away from the mold parting body 20. The ejector grooves 19 are matched with the mounting block 18, and the inner cavity of the ejector groove 19 is connected to the inner cavity of the threaded hole 181. The ejector block 191 is placed in the ejector groove 19.
[0099] In this embodiment, the threaded hole 181 is used to place a matching screw;
[0100] Before the web plate 31 of the double-sided closed beam part is separated from the main mold body 10, the screw in the threaded hole 181 continues to rotate and moves toward the ejector block 191, causing the ejector block 191 to be ejected and displaced, resulting in a gap between the flange 32 and the main mold body 10.
[0101] Of course, the preferred gap width is between 5mm and 10mm.
[0102] Specifically, the demolding auxiliary component 40 includes a T-slot platform 41, a limiting plate 42 is provided on the T-slot platform 41, a limiting bolt 43 is provided on the limiting plate 42, the head of the limiting bolt 43 extends into the groove of the T-slot platform 41, and a limiting nut (not shown in the figure) is threaded on the outer wall of the limiting bolt 43.
[0103] The limiting plate 42 is also provided with a sliding groove 44, and a connecting nut 45 is provided on the sliding groove 44. A connecting bolt (not shown in the figure) is provided in the connecting nut 45.
[0104] In this case, the diagram shows the limiting plate 42 limiting the mold parting plate 21. In actual use, the main mold parting plate 11 needs to be limited, thereby limiting the main mold body 10.
[0105] In this embodiment, when limiting the main mold body 10, the connecting bolts are first inserted into the holes of the main mold ear plate 11 from bottom to top and connected with the connecting nut 45. Then, the limiting bolts 43 and connecting bolts on the limiting plate 42 are inserted into the T-slot platform 41 and tightened to limit the main mold ear plate 11, thereby limiting the main mold body 10 on the demolding auxiliary component 40.
[0106] Specifically, an auxiliary support 46 is provided at the bottom of the T-shaped groove platform 41, and a through movable groove 47 is provided on the T-shaped groove platform 41.
[0107] The ejection assembly 50 includes a protective cylinder 51, on which a universal joint 54 is provided. A lifting screw 53 is provided inside the protective cylinder 51, and the universal joint 54 is connected to the lifting screw 53. A rotating handle 52 is also provided on the protective cylinder 51. The rotating handle 52 cooperates with the lifting screw 53, so that the lifting screw 53 drives the universal joint 54 to rise. The universal joint 54 contacts the inner wall of the top of the mold part 20 through the movable groove 47, so that the mold part 20 is separated from the main mold body 10.
[0108] In this case, the bottom of the auxiliary bracket 46 is equipped with multiple sets of casters.
[0109] In this embodiment, when the mold part 20 is raised, the lifting screw 53 inside the protective cylinder 51 is raised by rotating the handle 52, thereby raising the universal head 54 until the universal head 54 contacts the inner wall of the top of the mold part 20, thereby causing the mold part 20 to separate from the main mold 10.
[0110] A demolding method for a forming mold of a double-sided closed beam includes the following steps:
[0111] S1. Mold Design:
[0112] Based on the inner surface of the double-sided closed beam, the main structure is designed on the surface of the main mold body 10 and the parting mold body 20 respectively, so that the inner surface of the double-sided closed beam is precisely fitted onto the surface of the main mold body 10 and the parting mold body 20.
[0113] S2, Mold Positioning:
[0114] After the mold design is completed in S1, align the main mold pin hole 14 and the parting mold pin hole 25 and insert the pins. At the same time, install bolts in the main mold mounting hole 16 and the parting mold mounting hole 28 to connect the main mold body 10 and the parting mold body 20 into a whole.
[0115] S3, Part Forming:
[0116] The double-sided closed beam parts are formed on the main mold body 10 and the parting mold body 20, which are integrated in S2 and mold positioning.
[0117] S4, Auxiliary Limiter:
[0118] S3, the main mold body 10 and the part forming body 20 are placed on multiple sets of demolding auxiliary components 40, and the main mold body 10 is limited.
[0119] S5, Mold body disconnection:
[0120] After S4 and auxiliary limiting are completed, the pins and bolts in S2 and mold positioning are disassembled until the main mold body 10 is no longer connected to the mold part 20 as a whole.
[0121] S6, Edge separation:
[0122] The ejector block 191 is ejected from the ejector slot 19 by bolting it into the threaded hole 181 and continuously rotating it, so that there is a gap between the flange 32 on the double-sided closed beam part and the outer wall of the main mold body 10, the gap being 5mm-10mm.
[0123] S7. Separation of the web plate:
[0124] Rotate multiple sets of rotating handles 52 respectively, so that multiple sets of universal heads 54 contact the top inner wall of the mold part 20 through multiple sets of movable grooves 47 respectively. After all contacts are made, rotate the rotating handles 52 again, so that the mold part 20 is slowly lifted along the axis of the guide column 17, and the web plate 31 on the double-sided closed beam part is separated from the main mold body 10.
[0125] S8. Part unloading:
[0126] Completely detach the double-sided closed beam parts from the parting body 20 during the separation of S7 and the web plate, thus completing the demolding process of the double-sided closed beam parts.
[0127] In this embodiment, by using the above demolding method, when demolding the double-sided closed beam part, different positions of the double-sided closed beam part can be demolded separately. During the demolding process, it is not necessary to hammer the double-sided closed beam part, which can effectively improve the quality of the double-sided closed beam part, avoid damage to the double-sided closed beam part caused by hammering, and effectively solve the problem of difficult demolding of double-sided closed beam parts.
[0128] By using the above demolding method, when demolding double-sided closed beam parts, no manual hammering is required, which can effectively improve demolding efficiency, save manpower, and facilitate mass production.
[0129] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
