Description

Technical Field

[0001] This invention relates to an integrated mold for laying out a composite material double-ear rotating seat, belonging to the field of composite material laying out molding technology. Background Technology

[0002] Advanced composite materials, with their outstanding advantages such as high specific strength and specific modulus, low coefficient of thermal expansion, good designability, and ease of integral molding, have been widely used in aerospace, rail transportation, weaponry, and civilian products. Prepreg integral lay-up molding, as one of the major molding methods for advanced composite materials, is widely used in the commercial aerospace field. Prepreg lay-up molding involves laying prepreg fibers in a mold to ensure maximum fiber continuity and minimize fiber axial segmentation. The mold structure often determines the degree of lay-up continuity. With the increasing application of composite double-ear rotary seats in the aerospace field, it has become a typical structure in composite structural components. Integral lay-up molding is a crucial step in ensuring the performance of composite structural components. Therefore, the design of the molding die, as the most important tool in integral lay-up molding, to achieve lay-up, curing, demolding, dimensional assurance, and reusability is a subject worthy of in-depth research.

[0003] This type of composite material double-ear rotating seat has a complex structure and a cumbersome molding process. In the past, it was made by split molding, where the composite material double-ear rotating seat was divided into several parts, molded separately, and then assembled together by mechanical connection and bonding, or it was made into an internal skeleton and an outer shell, molded separately and then assembled together. This split molding and reassembly method results in discontinuous fibers in the overall composite material double-ear rotating seat, and the excessive use of mechanical connections and adhesives on the body greatly reduces the strength of the fiber composite material and loses its designability.

[0004] However, there is currently no molding method that can integrally form a composite material double-ear rotating seat, and existing molding dies cannot achieve integral molding of the composite material double-ear rotating seat. Summary of the Invention

[0005] In view of this, in order to solve the problem that existing molding dies cannot integrally mold composite material double-ear rotating seats, this invention proposes an integral laying molding die for composite material double-ear rotating seats, which is used to manufacture composite material double-ear rotating seats.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

The bottom of the side-standing assemblies is provided with straight stops, and the bottom of the arc-shaped pressure blocks is provided with arc-shaped stops. The component is positioned by engaging with a corresponding straight positioning stop through a straight stop. The arc-shaped pressure block is positioned by engaging with a corresponding arc-shaped positioning stop through an arc-shaped stop. The side-standing component and the arc-shaped pressure block are arranged in a rectangle following the shape of the positioning stop. The pressure outer frame is fixedly connected to the base plate by positioning pins and is located outside the rectangle formed by the side-standing component and the arc-shaped pressure block. The lower surface of the upper end of the spherical positioning cover overlaps the upper surface of the side-standing component. The side ears of the spherical positioning cover overlap the upper surface of the arc-shaped pressure block. The spherical positioning cover is bolted to the base plate.

[0008] Furthermore, the side-standing assembly also includes a standing plate, an arc-shaped plate, a shaft hole plate, a first inner hole forming core mold, a side cavity mold, a second inner hole forming core mold, a first side small cavity mold, and a second side small cavity mold.

The first side small cavity mold is bolted to the standing plate located above the first inner hole forming core mold, and the second side small cavity mold is bolted to the standing plate located above the second inner hole forming core mold.

[0009] Furthermore, a positioning boss is provided on the upright plate of the side-standing component.

[0012] Furthermore, the side of the arc-shaped pressure block near the central mold core is arc-shaped, and the upper end of the arc-shaped side has an arc-shaped groove that matches the side lug of the spherical positioning cover.

[0013] Furthermore, the spherical positioning cover has a hollow structure, a first pressure light hole is provided on the spherical positioning cover, and a second pressure light hole corresponding to the first pressure light hole is provided on the bottom plate.

[0014] Furthermore, a first guide groove is provided at the lower end of the base plate, and a second guide groove is provided at the lower end of the pressure frame opposite to the first guide groove.

[0015] Furthermore, the pressure-pressurizing outer frame has a pressure-pressurizing threaded hole on its side, and a first observation window and a second observation window are opened on both sides near the arc-shaped pressure block.

[0016] Furthermore, the base plate positioning assembly, the side standing assembly, the arc pressure block, the spherical positioning cover, and the pressure frame are all made of metal.

[0062] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other, and the described embodiments are only some embodiments of the present invention, not all embodiments.

[0063] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0064] Referring to the accompanying drawings, this embodiment describes a composite material double-ear rotating seat integral laying molding mold, including a base plate positioning assembly 4, a spherical positioning cover 3, a pressure outer frame 5, two side-standing components 1, and two arc-shaped pressure blocks 2. The base plate positioning assembly 4 includes a central core mold 4-2 and a base plate 4-1. The central core mold 4-2 is connected to the center of the base plate 4-1. The base plate 4-1 is provided with positioning stops and contacts the bottom side of the central core mold 4-2. The positioning stops include two opposing straight positioning stops 4-3 and two opposing arc-shaped positioning stops 4-4. The bottom of the side-standing components 1 is provided with straight stops 1-17, and the bottom of the arc-shaped pressure blocks 2 is provided with arc-shaped stops. 2-2, the side-standing component 1 is positioned by cooperating with the corresponding straight positioning stop 4-3 through the straight stop 1-17, and the arc-shaped pressure block 2 is positioned by cooperating with the corresponding arc-shaped positioning stop 4-4 through the arc-shaped stop 2-2. The side-standing component 1 and the arc-shaped pressure block 2 are arranged into a rectangle according to the shape of the positioning stop. The pressure outer frame 5 is fixedly connected to the base plate 4-1 by positioning pin and is located outside the rectangle formed by the side-standing component 1 and the arc-shaped pressure block 2. The lower surface of the upper end of the spherical positioning cover 3 overlaps the upper surface of the side-standing component 1, and the side ear 3-1 of the spherical positioning cover 3 overlaps the upper surface of the arc-shaped pressure block 2. The spherical positioning cover 3 is bolted to the base plate 4-2.

[0065] This invention provides a composite material double-ear rotating seat integrated laying and molding mold. This mold has high dimensional accuracy and is easy to operate, enabling integrated molding of composite material double-ear rotating seats. By laying fiber prepreg onto the side of the upright plate 1-1 of the mold, where the arc panel 1-2 is located, and then passing through the plane between the lower surface of the spherical positioning cover 3 and the upper surface of the central core mold 4-2, the fiber prepreg also fills the space between the arc-shaped pressure block 2 and the central core mold 4-2. This ensures the fiber prepreg is laid out conformally on the mold, guaranteeing maximum fiber continuity and reducing [burden / contamination]. By dividing the fiber axis, the strength of the final composite double-ear rotating seat is effectively guaranteed, which can better give play to the mechanical properties of the composite material. It can realize the integrated and complete laying and molding of the composite double-ear rotating seat, which greatly improves the fiber strength of the composite material and effectively avoids the performance damage caused by the mechanical connection of the split molding. The present invention provides a composite double-ear rotating seat integrated laying and molding mold. The composite double-ear rotating seat integrated laying and molding mold provides lateral clamping force through the pressure outer frame 5. The pressure outer frame 5 can make the side upright component 1 and the arc pressure block 2 press against the composite material, which greatly ensures the dimensional accuracy of the composite double-ear rotating seat and improves the surface quality of the composite double-ear rotating seat.

[0066] The side-standing component 1 further includes a standing plate 1-1, an arc-shaped panel 1-2, a shaft hole plate 1-3, a first inner hole forming core mold 1-4, a side cavity mold 1-5, a second inner hole forming core mold 1-6, a first side small cavity mold 1-7, and a second side small cavity mold 1-8. The arc-shaped panel 1-2 and the shaft hole plate 1-3 are bolted to the standing plate 1-1 in sequence. The side cavity mold 1-5 is bolted to the standing plate 1-1 located below the shaft hole plate 1-3. The first inner hole forming core mold 1-4 and the second inner hole forming core mold 1-6 are respectively bolted to the standing plates 1-1 on both sides of the side cavity mold 1-5. The first side small cavity mold 1-7 is bolted to the standing plate 1-1 located above the first inner hole forming core mold 1-4. The second side small cavity mold 1-8 is bolted to the standing plate 1-1 located above the second inner hole forming core mold 1-6. The arc panel 1-2 positions the shaft hole plate 1-3, and the shaft hole plate 1-3 forms the two annular supports of the composite material double-ear rotating seat. The first inner hole forming core mold 1-4, the side cavity mold 1-5, and the second inner hole forming core mold 1-6 form the opening cavity of the cylindrical structure outer wall of the composite material double-ear rotating seat. Preferably, the side cavity mold 1-5 is designed with a smaller size closer to the central shaft core mold 4-2 and a larger size farther away from the central shaft core mold 4-2. The second inner hole forming core mold 1-6 is a divisible structure. Both of these preferred structures are designed to facilitate demolding.

[0067] The upright plate 1-1 of the side-standing component 1 is provided with a positioning boss 1-1-1. The positioning boss 1-1-1 facilitates the positioning of the shaft hole plate 1-3, the first inner hole forming core mold 1-4, the side cavity mold 1-5, the second inner hole forming core mold 1-6, the first side small cavity mold 1-7, and the second side small cavity mold 1-8 on the upright plate 1-1.

[0068] The first inner hole forming core mold 1-4 is designed with a hollow structure. The hollow structure facilitates the screw connection of various small mold pieces for obtaining different details of composite material double-ear rotating seats on its surface. When screwed, the hollow structure can hide the screw, so the screw will not affect the flatness of the forming surface of the first inner hole forming core mold 1-4, ensuring the surface quality and dimensional accuracy of the composite material double-ear rotating seat.

[0069] Small mold pieces are bolted to the first inner hole forming core mold 1-4. These small mold pieces include a first small mold piece 1-9, a second small mold piece 1-10, a third small mold piece 1-11, a fourth small mold piece 1-12, a fifth small mold piece 1-13, a sixth small mold piece 1-14, a seventh small mold piece 1-15, and / or an eighth small mold piece 1-16. Different details of the composite material double-ear rotating seat are obtained by bolting the first inner hole forming core mold 1-4 to one or more small mold pieces. The design of the small mold pieces reduces the demolding difficulty of complex structures and minimizes damage to the main structure of the composite material double-ear rotating seat. Different shapes of composite material double-ear rotating seats can be formed simply by combining one or more small mold pieces, thus enabling the production of composite material double-ear rotating seats with different internal structures using this set of molds, improving the flexibility and adaptability of the molds in this application.

[0070] The side of the arc-shaped pressure block 2 near the central mold core 4-2 is arc-shaped, and the upper end of the arc-shaped side has an arc-shaped groove 2-1 that mates with the side ear 3-1 of the spherical positioning cover 3. The side of the arc-shaped pressure block 2 near the central mold core 4-2 is mainly used for forming the closed surface of the outer wall of the cylindrical structure. The arc-shaped groove 2-1 and the side ear 3-1 of the spherical positioning cover 3 are in contact to support the spherical positioning cover 3, which improves the integrity of the mold, facilitates the integrated and complete laying and molding of the composite material double-ear rotating seat, and improves the fiber strength of the composite material.

[0071] The spherical positioning cover 3 has a hollow structure. A first pressure-applying light hole 3-2 is provided on the spherical positioning cover 3, and a second pressure-applying light hole 4-6 corresponding to the first pressure-applying light hole 3-2 is provided on the base plate 4-1. The hollow structure reduces weight and the pressure on the side-standing component 1 and the arc-shaped pressure block 2. The long bolt passes through the first pressure-applying light hole 3-2 and the second pressure-applying light hole 4-6, thereby providing vertical pressure to the mold of this application. This ensures the dimensional accuracy of the composite material double-ear rotating seat while also improving the surface quality of the composite material double-ear rotating seat.

[0072] The lower end of the base plate 4-1 is provided with a first guide groove 4-5, and the lower end of the pressure outer frame 5 is provided with a second guide groove 5-4 opposite to the first guide groove 4-5. The pressure outer frame 5 is fixedly connected to the base plate positioning assembly 4 by connecting the first guide groove 4-5 and the second guide groove 5-4 with a positioning pin, thereby fixing the pressure outer frame 5 and improving the overall stability of the mold.

[0073] The pressure-pressuring outer frame 5 has pressure-pressuring threaded holes on its side, and a first observation window 5-1 and a second observation window 5-2 are opened on both sides near the arc-shaped pressure block 2. A screw passes through the threaded holes on the side of the pressure-pressuring outer frame 5 and presses against the surfaces of the side-standing component 1 and the arc-shaped pressure block 2 to provide circumferential pressure to the mold, ensuring the dimensional accuracy of the composite material double-ear rotary seat and improving the surface quality of the composite material double-ear rotary seat. The first observation window 5-1 facilitates real-time observation of the positioning and molding process, while the second observation window 5-2 facilitates real-time observation of the mold closing gap.

[0074] The base plate positioning component 4, the side standing component 1, the arc-shaped pressure block 2, the spherical positioning cover 3, and the pressure outer frame 5 are all made of metal. The metal material ensures the dimensional accuracy of the composite material double-ear rotating seat and improves the surface quality of the composite material double-ear rotating seat.

[0075] The present invention discloses a composite material double-ear rotating seat integral laying molding mold, the specific working steps of which are as follows:

[0076] Assembly and Mold Closure: Assemble the side support component 1 and the base plate positioning component 4 respectively. The side support component 1 and the arc pressure block 2 are installed on the base plate positioning component 4 through the positioning stop. The pressure outer frame 5 and the base plate positioning component 4 are connected by the positioning pin. The spherical positioning cover 3 is installed on the upper surface of the side support component 1 and the arc pressure block 2. The spherical positioning cover 3 and the base plate 4-1 are pressurized by the long bolt passing through the first pressure light hole 3-2 and the second pressure light hole 4-6, thereby providing vertical pressure. The screw passes through the threaded hole on the side of the pressure outer frame 5 and reaches the surface of the side support component 1 and the arc pressure block 2 to provide circumferential pressure to the mold. At this point, all pressurization and fixing have been achieved, and the mold assembly is completed.

[0077] Demolding: Loosen the bolts on the spherical positioning cover 3 and the base plate positioning assembly 4 in sequence, and the screws on the side of the pressure frame 5. At this time, the spherical positioning cover 3 and the pressure frame 5 can be disassembled in sequence. At this time, the remaining side standing assembly 1 and the arc pressure block 2 are connected to the base plate positioning assembly 4. Remove the arc pressure block 2. The side standing assembly 1 needs to be removed first. At this time, the other parts of the side standing assembly 1 are located on the surface of the cured composite material double ear rotating seat. Remove the remaining components through the threaded holes connected to the upright plate. Finally, pull the cured composite material double ear rotating seat out of the central core mold to complete the demolding.
