Description

Technical Field

[0001] This utility model relates to the field of aerospace composite material technology, specifically a molding tooling for aerospace composite materials. Background Technology

[0002] Carbon fiber composites play a vital role in the aerospace field due to their superior properties such as high strength, high stiffness, lightweight, corrosion resistance, and fatigue resistance, making them widely used in spacecraft structures, propulsion, and thermal protection systems. Therefore, the molding process of carbon fiber materials is particularly crucial; hence, we have developed a carbon fiber layup molding tooling.

[0003] Traditional carbon fiber molding processes have shortcomings in stability and precision control. The lack of effective shaping methods after prepreg laying makes it difficult for molded carbon fiber products to meet the high standards of dimensional accuracy and structural stability required for aerospace components. Simultaneously, the cooling process after molding is inefficient; conventional cooling methods consume significant time, impacting production schedules, and resulting in poor uniformity, easily leading to stress concentration within the product and reducing performance. Furthermore, existing tooling is inconvenient for handling mold bodies, lacking a convenient and efficient handling design, increasing labor and time costs. These problems severely restrict the development of aerospace composite material molding technology, urgently requiring innovative solutions to improve molding process levels.

[0004] Therefore, this utility model provides a composite material molding tooling for aerospace applications. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a composite material molding tooling for aerospace applications to solve the above problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a composite material molding fixture for aerospace, including a base, a mold body fixedly connected to the top of the base, and a cooling mechanism provided on the outer side of the base;

[0007] The cooling mechanism includes a connecting plate, a motor is fixedly connected to the outer side of the connecting plate, a lead screw is fixedly connected to the output end of the motor, a collar is threadedly connected to the outer side of the lead screw, a limit rod is fixedly connected to the outer side of the collar, a moving groove is opened in the side wall of the base, an air outlet plate is fixedly connected to the top of the collar, a refrigeration unit is fixedly connected to the outer side of the base, and a ducted air hose is fixedly connected to the outer side of the refrigeration unit.

[0008] Preferably, a transport mechanism is provided on the outer side of the base. The transport mechanism includes a sliding groove, in which a support rod is slidably engaged, and a handle is fixedly connected to the outer side of the support rod.

[0009] Preferably, the connecting plates are fixed and symmetrically distributed on the outside of the base, and the lead screw is rotatably connected between the two connecting plates. By starting the motor, the motor drives the lead screw to rotate between the two connecting plates.

[0010] Preferably, the end of the limiting rod away from the collar is slidably connected inside the moving groove, and the air vent plate is located on both sides of the mold body. Since one end of the limiting rod is slidably connected inside the moving groove, it can limit the collar.

[0011] Preferably, the air guide hoses are symmetrically distributed on the outside of the refrigerator, and the end of the air guide hose away from the refrigerator is fixedly connected to the inside of the air outlet plate. When the refrigerator is started, the generated cold air enters the inside of the air outlet plate through the air guide hoses.

[0012] Preferably, the sliding grooves are symmetrically distributed inside the base, and the support rod is adapted to the sliding grooves. The support rod is slidably engaged inside the sliding grooves, thus enabling the handle to move on the outside of the base.

[0013] Preferably, the handle is movably connected to the outside of the base via a support rod, and the handles are symmetrically distributed on the outside of the base. When it is not necessary to move the base and the mold body, the handle can be moved to the outside of the base, thereby reducing the space occupied.

[0014] Beneficial effects

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] (1) The aerospace composite material molding fixture is equipped with a base, and a mold body is fixedly connected to the top of the base. The prepreg is laid on the mold layer by layer for shaping, which can better ensure the molding stability of carbon fiber and ensure the molding accuracy of carbon fiber. After the shaping is completed, the refrigeration machine and motor are started. At this time, the cold air generated by the refrigeration machine will enter the interior of the air outlet plate through the air guide hose and then flow out through the air outlet plate, thereby accelerating the cooling. Since the motor will drive the lead screw to rotate, the rotation of the lead screw will drive the collar to rotate. A limit rod is fixedly connected to the outside of the collar, so it can limit the collar, thereby causing the collar to drive the air outlet plate to move, thereby improving the cooling efficiency.

[0017] (2) The aerospace composite material molding tooling is equipped with a base and a mold body. When the mold body needs to be moved, the support rod slides inside the sliding groove, thereby moving the handle to the outside of the base. Then, the base and the mold body can be easily moved through the handle. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 A composite material molding tooling for aerospace applications includes a base 1, a mold body 2 fixedly connected to the top of the base 1, and a cooling mechanism 3 provided on the outside of the base 1.

[0025] The cooling mechanism 3 includes a connecting plate 31, a motor 32 is fixedly connected to the outside of the connecting plate 31, a lead screw 33 is fixedly connected to the output end of the motor 32, a collar 34 is threadedly connected to the outside of the lead screw 33, a limit rod 35 is fixedly connected to the outside of the collar 34, a moving groove 36 is opened in the side wall of the base 1, an air outlet plate 37 is fixedly connected to the top of the collar 34, a refrigeration unit 38 is fixedly connected to the outside of the base 1, and a duct hose 39 is fixedly connected to the outside of the refrigeration unit 38.

[0026] Furthermore: the connecting plates 31 are fixed and symmetrically distributed on the outside of the base 1, the lead screw 33 is rotatably connected between the two connecting plates 31, the end of the limiting rod 35 away from the collar 34 is slidably connected to the inside of the moving groove 36, the air outlet plate 37 is located on both sides of the mold body 2, the air guide hose 39 is symmetrically distributed on the outside of the refrigerator 38, and the end of the air guide hose 39 away from the refrigerator 38 is fixedly connected to the inside of the air outlet plate 37.

[0027] It should be noted that: by starting the motor 32, the motor 32 drives the lead screw 33 to rotate between the two connecting plates 31. Since one end of the limiting rod 35 is slidably connected inside the moving groove 36, it can limit the ring 34. By starting the refrigeration unit 38, the generated cold air enters the interior of the air outlet plate 37 through the air guide hose 39.

[0028] Specifically: Design suitable tooling based on the shape and size requirements of the part. The main function of the tooling is to apply uniform pressure to the part during the curing process to ensure molding quality. The size and shape of the mold must be consistent with the product requirements, and the thermal conductivity and sealing performance of the mold must also be considered.

[0029] As a further improvement of this utility model, a conveying mechanism 4 is provided on the outer side of the base 1. The conveying mechanism 4 includes a sliding groove 41, a support rod 42 is slidably engaged inside the sliding groove 41, and a handle 43 is fixedly connected to the outer side of the support rod 42.

[0030] Furthermore: the sliding grooves 41 are symmetrically distributed inside the base 1, the support rods 42 are adapted to the sliding grooves 41, and the handles 43 are movably connected to the outside of the base 1 through the support rods 42, and the handles 43 are symmetrically distributed on the outside of the base 1.

[0031] It should be noted that the support rod 42 is slidably engaged inside the sliding groove 41, thus enabling the handle 43 to move outside the base 1. When it is not necessary to move the base 1 and the mold body 2, the handle 43 can be moved to the outside of the base 1, thereby reducing the space occupied.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] Working principle: A base 1 is set up, and a mold body 2 is fixedly connected to the top of the base 1. The prepreg is laid layer by layer on the mold for shaping, which can better ensure the molding stability of carbon fiber and ensure the molding accuracy of carbon fiber. After the shaping is completed, the refrigeration unit 38 and the motor 32 are started. At this time, the cold air generated by the refrigeration unit 38 enters the interior of the air outlet plate 37 through the air guide hose 39, and then flows out through the air outlet plate 37, thereby accelerating the cooling. Since the motor 32 drives the lead screw 33 to rotate, the rotation of the lead screw 33... The movement will cause the collar 34 to rotate. A limit rod 35 is fixedly connected to the outside of the collar 34, which can limit the movement of the collar 34. This causes the collar 34 to move the air outlet plate 37, thereby improving the cooling efficiency. By setting the base 1 and the mold body 2, when the mold body 2 needs to be moved, the support rod 42 slides inside the sliding groove 41, thereby causing the support rod 42 to move the handle 43 to the outside of the base 1. Then, the handle 43 can be used to easily move the base 1 and the mold body 2.
