Description

Technical Field

[0001] This utility model relates to the field of composite material molding technology, and in particular to a molding die for polyimide aerogel composite materials. Background Technology

[0002] Polyimide aerogel (PIA) is a three-dimensional porous material composed of cross-linked polymer molecular chains. It combines the excellent properties of polyimide and aerogel, giving it not only the superior characteristics of polyimide but also the outstanding features of aerogel, such as lightweight, ultra-low density, high specific surface area, low thermal conductivity, and low dielectric constant. As a result, polyimide aerogel has rapidly developed into one of the high-performance organic aerogels and has shown broad application prospects in aerospace, electronic communications, thermal insulation and flame retardancy, sound insulation and absorption, and adsorption and cleaning.

[0003] Traditional molding molds typically require manual removal of the composite material after molding. Since the composite material generates high temperatures during the molding process, manual removal can easily cause burns, reducing safety during use. Therefore, we propose a molding mold for polyimide aerogel composite materials. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a molding die for polyimide aerogel composite materials.

[0005] This utility model is achieved using the following technical solution: a molding frame for polyimide aerogel composite materials, comprising a worktable, support columns fixedly connected to the four corners of the bottom of the worktable, a pushing assembly provided on the top of the worktable, a collecting frame fixedly connected to the inner wall of the worktable, a U-shaped frame fixedly connected to the top of the worktable, a lower mold fixedly connected to the top of the worktable, a plurality of heating tubes provided inside the lower mold, a hydraulic rod fixedly connected to the top of the U-shaped frame, the output end of the hydraulic rod passing through the U-shaped frame and fixedly connected to an upper mold, a guide rod fixedly connected to the top of the upper mold, a groove provided at the bottom of the lower mold, a discharge plate provided inside the groove, a cylinder fixedly connected to the bottom of the discharge plate, and a support frame fixedly connected to the bottom of the cylinder;

[0006] The feeding assembly includes a fixed frame, a lead screw is rotatably connected to the inner wall of the fixed frame, a motor is fixedly connected to one end of the fixed frame, a mounting bracket is threadedly connected to the surface of the lead screw, a limit rod is slidably connected to the inner wall of the mounting bracket, and a feeding plate is fixedly connected to one end of the mounting bracket.

[0007] The above technical solution pushes the unloading plate upward through the output end of the cylinder, pushing out the formed composite material. Then, the motor is started, and the motor drives the lead screw to rotate. Since the lead screw is threadedly connected to the mounting frame, the mounting frame moves, which drives the pusher plate to move and push the ejected composite material into the inside of the collection frame. This avoids manual material handling and improves the convenience and safety of use.

[0008] As a further improvement to the above solution, the bottom of the fixed frame is fixedly connected to the top of the workbench, and the output end of the motor is fixedly connected to one end of the lead screw.

[0009] As a further improvement to the above solution, the two ends of the limiting rod are fixedly connected to the inner wall of the fixing frame, and the pusher plate is located at the upper end of the lower mold.

[0010] The above technical solution uses a limiting rod to support and limit the mounting frame, preventing it from shifting during movement and ensuring stability during use.

[0011] As a further improvement to the above solution, the surface of the collection frame is provided with several through holes, and the collection frame is located at the front end of the lower mold.

[0012] The above technical solution allows external air to enter the interior of the collection frame through several through holes on the surface of the collection frame to cool the molded composite material, and the cooled composite material is collected through the collection frame.

[0013] As a further improvement to the above solution, the surface of the guide rod is slidably connected to the inner wall of the U-shaped frame, and the top of the support frame is fixedly connected to the bottom of the workbench.

[0014] The above technical solution uses guide rods to limit the upper mold, preventing it from shifting when moving downwards, thus ensuring precise docking between the upper and lower molds.

[0015] As a further improvement to the above solution, an extension plate is fixedly connected to the bottom of the workbench, and a fan is fixedly connected to one end of the extension plate.

[0016] With the above technical solution, the fans are located at both ends of the collection frame, and the fans blow air to cool the composite material inside the collection frame, thereby improving the cooling efficiency.

[0017] As a further improvement to the above solution, each extension plate is provided in pairs, and the two extension plates are symmetrically distributed around the worktable.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This utility model incorporates a pusher assembly, a discharge plate, and a cylinder. Specifically, the cylinder's output pushes the discharge plate upwards, ejecting the molded composite material. Then, a motor is started, driving a lead screw to rotate. Since the lead screw is threadedly connected to the mounting frame, the mounting frame moves, causing the pusher plate to move and push the ejected composite material into the collection frame. This eliminates the need for manual material handling, improving convenience and safety during use.

[0020] This invention uses a collection frame and a fan. Specifically, the collection frame collects the molded composite material, and the fan blows air through the composite material inside the collection frame to cool it down, thereby accelerating the cooling process and improving production efficiency.

[0029] Please combine Figure 1-5This embodiment of a polyimide aerogel composite material molding die includes a workbench 1, support columns 2 fixedly connected to the four corners of the bottom of the workbench 1, a pusher assembly 3 provided on the top of the workbench 1, a collection frame 4 fixedly connected to the inner wall of the workbench 1, a U-shaped frame 5 fixedly connected to the top of the workbench 1, a lower mold 6 fixedly connected to the top of the workbench 1, a plurality of heating tubes provided inside the lower mold 6, a hydraulic rod 7 fixedly connected to the top of the U-shaped frame 5, the output end of the hydraulic rod 7 passing through the U-shaped frame 5 and fixedly connected to an upper mold 8, a guide rod 9 fixedly connected to the top of the upper mold 8, a groove provided at the bottom of the lower mold 6, a discharge plate 10 provided inside the groove, a cylinder 11 fixedly connected to the bottom of the discharge plate 10, and a support frame 12 fixedly connected to the bottom of the cylinder 11.

[0030] The feeding assembly 3 includes a fixed frame 301, with a lead screw 302 rotatably connected to the inner wall of the fixed frame 301. A motor 303 is fixedly connected to one end of the fixed frame 301, and a mounting frame 304 is threadedly connected to the surface of the lead screw 302. A limit rod 305 is slidably connected to the inner wall of the mounting frame 304, and a feeding plate 306 is fixedly connected to one end of the mounting frame 304. After heating is completed, the output end of the hydraulic rod 7 retracts, driving the upper mold 8 to move upward. Then, the cylinder 11 is activated, and the output end of the cylinder 11 pushes the unloading plate 10 upward, pushing out the formed composite material. Then, the motor 303 is activated, driving the lead screw 302 to rotate. Since the lead screw 302 is threadedly connected to the mounting frame 304, the mounting frame 304 moves, driving the feeding plate 306 to move and push the ejected composite material into the collection frame 4, avoiding manual material handling and improving the convenience and safety of use.

[0031] The bottom of the fixed frame 301 is fixedly connected to the top of the worktable 1, and the output end of the motor 303 is fixedly connected to one end of the lead screw 302.

[0032] The two ends of the limiting rod 305 are fixedly connected to the inner wall of the fixed frame 301, and the pusher plate 306 is located at the upper end of the lower mold 6.

[0033] The surface of the collection frame 4 has several through holes. The collection frame 4 is located at the front end of the lower mold 6 and the molded composite material is collected through the collection frame 4.

[0034] The surface of the guide rod 9 is slidably connected to the inner wall of the U-shaped frame 5, and the top of the support frame 12 is fixedly connected to the bottom of the workbench 1.

[0035] An extension plate 13 is fixedly connected to the bottom of the workbench 1, and a fan 14 is fixedly connected to one end of the extension plate 13. The fan 14 blows air to cool down the composite material inside the collection frame 4, accelerates the cooling process, and improves production efficiency.

[0036] There are two extension plates 13, and the two extension plates 13 are symmetrically distributed with the worktable 1 as the center.

[0037] The implementation principle of the polyimide aerogel composite material molding die in this embodiment is as follows: First, the polyimide aerogel composite material is placed inside the lower mold 6. Then, the hydraulic rod 7 is activated, and its output end pushes the upper mold 8 downwards. The upper mold 8 closes with the lower mold 6, applying pressure to the material. The heating tube inside the lower mold 6 is activated to heat the material. The material undergoes a chemical reaction at high temperature, forming a stable polyimide aerogel composite material. After heating is complete, the output end of the hydraulic rod 7 retracts, causing the upper mold 8 to move upwards. Then, the cylinder 11 is activated, and the cylinder 11... The discharge plate 10 is pushed upward to push out the formed composite material. Then, the motor 303 is started, which drives the lead screw 302 to rotate. Since the lead screw 302 is threadedly connected to the mounting frame 304, the mounting frame 304 moves, which drives the pusher plate 306 to move and push the ejected composite material into the collection frame 4. This avoids manual material handling and improves the convenience and safety of use. The formed composite material is collected through the collection frame 4. Then, the fan 14 is started to blow air into the composite material inside the collection frame 4 to cool it down, accelerate the cooling process, and improve production efficiency.
