Description

Technical Field

[0001] This utility model relates to autoclave molding molds, specifically a high-efficiency composite material autoclave molding mold. Background Technology

[0002] Composite materials are novel materials created by combining two or more materials with different properties through physical or chemical methods, and their performance is superior to that of the single materials that compose them. Generally, the process of curing composite materials in an autoclave involves heating, holding, cooling, and simultaneously pressurizing and depressurizing. During the heating phase, resistance wires continuously heat the air, using a fan as the power source and air as the heat transfer medium to continuously heat the mold and components, ensuring the component temperature rises continuously to complete the curing process. During cooling, the heating device is turned off, and water cooling is used to continuously cool the air inside the autoclave. The fan circulates the air, ensuring the temperature decreases throughout the autoclave.

[0003] Existing molding dies can be removed from the autoclave, but the connection between the die and the autoclave usually takes several minutes or even longer per operation, which affects the efficiency of workers in removing or changing the die, thus reducing processing efficiency.

[0014] 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.

[0015] Example 1 See Figure 1-5 A high-efficiency composite material autoclave molding die includes a main component 1, which includes: an autoclave 11, inside which a molding die 12 is disposed; a controller 13 disposed on the outer wall of the autoclave 11; and a connecting component 2 disposed on the main component 1, which includes: a moving mechanism 21 disposed on the autoclave 11; a base 22 disposed on the moving mechanism 21, with the molding die 12 located on top of the base 22; a slot 221 opened on top of the base 22; a first cavity 222 symmetrically opened inside the base 22, with the slot 221 communicating with the first cavity 222; and a second cavity 223 opened on the base. Inside the mold 22; a sliding rod 23, symmetrically penetrating and slidably disposed between cavity 1 222 and cavity 223; a limiting block 24, symmetrically and fixedly connected to the opposite ends of the sliding rod 23, the top of the limiting block 24 having an inclined surface; a spring 241, one end fixedly connected to the inner side wall of cavity 1 222, the other end fixedly connected to the outer side wall of the limiting block 24, the spring 241 being sleeved on the outside of the sliding rod 23; a fixing block 25, symmetrically and fixedly connected to the bottom of the molding mold 12; a limiting groove 251, formed on the fixing block 25; a push rod 26, penetrating and slidably connected to the base 22; and a linkage mechanism 27, disposed on the base 22 and the push rod 26. The moving mechanism 21 includes: a frame 211, fixedly connected to the top surface inside the autoclave 11; a lead screw 212, rotatably connected inside the frame 211; a support frame 213, threadedly connected to the outside of the lead screw 212, with the bottom end of the support frame 213 fixedly connected to the base 22; a motor 214, disposed on the outer wall of the autoclave 11, with the output shaft of the motor 214 fixedly connected to one end of the lead screw 212, and the motor 214 electrically connected to the controller 13. The linkage mechanism 27 includes: a push plate 271, fixedly connected to one end of the push rod 26 located inside the cavity 223; a connecting rod 272, with its two ends respectively hinged to the slide rod 23 and the push plate 271; a through groove 273, formed on the connecting rod 272; and a rotating rod 274, symmetrically and fixedly connected inside the cavity 223, the rotating rod 274 passing through the through groove 273.

[0016] In use, the operator moves the base 22 out of the autoclave 11 using the moving mechanism 21. The operator starts the motor 214 via the controller 13. The motor 214 drives the lead screw 212 to rotate, and the support frame 213 threaded onto the lead screw 212 moves the base 22 out of the autoclave 11. Then, the fixing block 25 at the bottom of the molding mold 12 is inserted into the slot 221. After the edge of the fixing block 25 contacts the inclined surface of the limiting block 24, the limiting block 24 is pushed into the cavity 222. The spring 241 is compressed. When the limiting groove 251 on the fixing block 25 moves to one side of the limiting block 24, the deformed and elastic spring 241 pops the limiting block 24 outward. The limiting block 24 is inserted into the limiting groove 251, limiting the fixing block 25, thereby achieving the connection between the base 22 and the molding mold 12, which is relatively convenient and quick.

[0017] Workers spray a release agent onto the molding mold 12, then precisely lay layers of composite material on its surface according to the designed angles and sequence. A series of auxiliary materials are then applied over the layered material. Finally, a large, heat-resistant vacuum bag film is used to seal the molding mold 12 and the material. After the molding mold 12 is sealed, the worker controls the motor 214 to rotate in reverse, and the base 22 moves the molding mold 12 into the autoclave 11. The autoclave 11 automatically operates according to a preset curing program, injecting compressed air into the canister. This immense pressure is evenly applied to the composite material through the vacuum bag and the molding mold 12, compacting it tightly. Simultaneously, the autoclave begins heating, precisely raising the temperature of the gas inside according to the program. Heat is transferred through gas convection and mold conduction, causing the resin in the composite material to melt, flow, and ultimately undergo a cross-linking reaction to solidify. This process is maintained at a specific temperature and pressure for a period of time to ensure complete resin curing. After curing, heating is stopped, and the material is allowed to cool naturally or by forced cooling. Once the temperature drops to a safe range, the pressure inside the canister is released first, and then the vacuum is released. The specific structure of the autoclave 11 will not be described in detail here.

[0018] When the operator needs to remove the molding die 12, they first move the base 22 out, then remove the auxiliary materials outside the molding die 12, and press the push rod 26 on one side of the base 22. The push rod 26, through the linkage mechanism 27, moves the sliding rods 23 on both sides into the cavity 223 simultaneously. When the operator presses the push rod 26, the push rod 26 pushes the push plate 271 to move. The push plate 271 causes one end of the connecting rod 272, which is hinged to it, to tilt. The connecting rod 272 rotates along the rotating rod 274, which can move within the through groove 273 to prevent the connecting rod 272 from getting stuck. The connecting rod 272 then causes the sliding rod 23, which is hinged to the other end, to gradually extend into the cavity 223. The sliding rod 23, in conjunction with the two limiting blocks 24, simultaneously pulls out of the limiting groove 251. At this point, the molding die 12 can be removed from the base 22 for subsequent replacement or maintenance.

[0019] Example 2 An auxiliary function has been added based on Embodiment 1.

[0020] See Figure 1-5 The push plate 271 and the cavity 223 are fixedly connected to each other by a spring 4. The top of the base 22 is symmetrically and fixedly connected to guide posts 3, and the bottom of the molding mold 12 is symmetrically provided with guide grooves 31. The top of the support frame 213 is slidably connected to the inside of the frame 211.

[0021] When the operator presses the push rod 26, the spring 4 connected to the connecting rod 272 contracts. When the molding mold 12 is removed and the push rod 26 is released, the spring 4, after deformation, pushes the connecting rod 272 back to its original position, thus facilitating the automatic return of each component of the linkage mechanism 27 to its original position for future use. When the operator installs the molding mold 12, the guide groove 31 at the bottom of the molding mold 12 is inserted into the guide post 3, thereby enhancing the positioning effect of the molding mold 12. When the top of the support frame 213 is slidably connected to the frame 211, the internal space of the frame 211 guides the top of the support frame 213, thereby increasing the stability of the support frame 213 when moving the base 22.

[0022] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
