Description

Technical Field

[0001] This utility model relates to the technical field of molds, and more specifically, to a one-time molding mold for ribbed products. Background Technology

[0002] Autoclave molding, a common technology in composite material processing, involves first precisely designing and manufacturing a mold based on the product's specific shape and dimensions. Pre-cut reinforcing materials—often fiber prepregs such as fiberglass cloth or carbon fiber cloth—are then layered onto the inner surface of the mold according to the design requirements. Commonly used materials include unsaturated polyester resin and epoxy resin. Vacuum bag pressure is applied to ensure thorough impregnation, allowing the fiber material and adhesive to bond tightly, forming a composite layer with both strength and toughness. After layering to the designed thickness, heating accelerates the curing reaction, causing the adhesive to cross-link and harden, ultimately molding a product that perfectly matches the mold shape.

[0003] This process demonstrates strong applicability in manufacturing workpieces with a certain framework, such as cylindrical structures, but it has significant limitations. Traditional solutions require the separate fabrication of stiffening plates, which are then connected to the main body of the workpiece via bonding or riveting. This not only increases the process flow and extends the production cycle, leading to higher labor and material costs, but more importantly, secondary connections are prone to stress concentration, and the strength of the joint surfaces is often lower than that of the integrally formed structure. This directly affects the structural integrity and mechanical properties of the finished product, reducing its quality stability. Therefore, designing an integrated mold capable of forming stiffening plate structures in a single operation is of great significance. Utility Model Content

[0004] The purpose of this utility model is to provide a one-time molding mold for ribbed products, which can simultaneously complete the fabrication of the rib structure when making the main body of the workpiece, and the rib structure and the main body structure are integrated.

[0005] This utility model is achieved through the following technical solution: The one-time molding mold for ribbed products of this utility model includes a mold cylinder and multiple rib modules; the multiple rib modules are arranged to form a ring structure; the multiple rib modules are disposed inside one end of the mold cylinder, the side of the rib module near the end of the mold cylinder is attached to the inner wall of the mold cylinder, and the side of the rib module away from the end of the mold cylinder is provided with a gap between it and the inner wall of the mold cylinder.

[0006] Furthermore, the rib module is detachably connected to the mold cylinder.

[0007] Furthermore, the mold cylinder is formed by multiple mold plates.

[0008] Furthermore, one of the mold plates is detachably connected to one of the rib modules.

[0009] Furthermore, the side of the rib module near the end of the mold plate is connected to the mold plate by a first bolt.

[0010] Furthermore, one or more of the mold plates have through holes on their sidewalls, and a sealing plate is detachably provided at the through holes.

[0011] Furthermore, the sealing plate is connected to the mold plate by bolts.

[0012] The technical solution of this utility model has at least the following advantages and beneficial effects: The one-time molding mold for ribbed products of this utility model first performs layer-layout molding on the inner wall of the mold cylinder, that is, coating the fiber raw material and adhesive on the inner wall of the mold cylinder to form according to the shape of the mold cylinder. However, the fiber material is not coated on the end of the mold cylinder near the rib module. Then, the rib module is installed on the end of the mold cylinder, so that there is a gap between the outer wall of the rib module and the inner wall of the mold cylinder. This gap is used to accommodate the previously coated fiber material. Then, the fiber material is coated on the side of the rib module away from the mold cylinder and connected with the fiber material on the inner wall of the mold cylinder. In this way, an integral ring-shaped rib plate can be formed through the rib module. The rib plate is directly integrally formed with the inner wall of the mold cylinder, without the need for subsequent assembly or separate manufacturing, resulting in higher processing efficiency and better finished product quality.

[0015] Example The following description, in conjunction with specific embodiments, further illustrates the points, as shown in the appendix. Figure 1 - Appendix Figure 5As shown, the one-time molding mold for ribbed products in this embodiment includes a mold cylinder 10 and a plurality of rib modules 20; the plurality of rib modules 20 are arranged to form an annular structure; the plurality of rib modules 20 are disposed inside one end of the mold cylinder 10, the side of the rib module 20 near the end of the mold cylinder 10 is attached to the inner wall of the mold cylinder 10, and a gap 14 is provided between the side of the rib module 20 away from the end of the mold cylinder 10 and the inner wall of the mold cylinder 10. Specifically, during use, a layer-layout process is first performed on the inner wall of the mold cylinder 10, that is, fiber raw materials and adhesives are coated on the inner wall of the mold cylinder 10 to form the shape of the mold cylinder 10. However, the fiber material is not coated on the end of the mold cylinder 10 near the rib module 20. Then, the rib module 20 is installed on the end of the mold cylinder 10, so that there is a gap 14 between the outer wall of the rib module 20 and the inner wall of the mold cylinder 10. Multiple gaps 14 are interconnected to form a ring structure. The gap 14 is used to accommodate the previously coated fiber material. Then, fiber material is coated on the side of the rib module 20 away from the mold cylinder 10 and connected with the fiber material on the inner wall of the mold cylinder 10. In this way, an integral ring-shaped rib plate can be formed through the rib module 20. The rib plate is directly integrally formed with part of the inner wall of the mold cylinder 10 without subsequent assembly or separate manufacturing, resulting in higher processing efficiency and better product quality.

[0016] In this embodiment, the rib module 20 is detachably connected to the mold cylinder 10. Specifically, during molding, the molding material is first attached to the inner wall of the mold cylinder 10, then the rib module 20 is fixed to the end of the mold cylinder 10, and then the molding material is attached to the side of the rib module 20 to form a T-shaped rib. After pressing, heating, curing and other processes, the rib module 20 is removed first, and then the workpiece is taken out of the mold cylinder 10.

[0017] In this embodiment, the mold cylinder 10 is formed by multiple mold plates 11. Specifically, this allows for better shaping of the mold cylinder 10 and also enables the workpiece to be quickly removed from the mold cylinder 10 by disassembling the mold plates 11.

[0018] In this embodiment, a mold plate 11 and a rib module 20 are detachably connected. The side of the rib module 20 near the end of the mold plate 11 is connected to the mold plate 11 by a first bolt. Specifically, this allows the fascia block to be quickly fixed to the mold plate 11 and can also be quickly removed later.

[0019] In this embodiment, one or more mold plates 11 have through holes 12 on their side walls, and a sealing plate 13 is detachably installed at the through hole 12. The sealing plate 13 is connected to the mold plate 11 by bolts. For some workpieces, the preparation does not require complete coverage of the entire inner wall of the mold cylinder 10. Therefore, through holes 12 can be opened on the mold plate 11, allowing operation inside the mold cylinder 10 through the through holes 12, making the molding process more convenient and efficient.

[0020] In summary, the one-time molding die for ribbed products of this embodiment first performs layer-layout molding on the inner wall of the die cylinder 10, that is, coating the fiber material and adhesive onto the inner wall of the die cylinder 10 to form the shape of the die cylinder 10. However, the fiber material is not coated on the end of the die cylinder 10 near the rib module 20. Then, the rib module 20 is installed on the end of the die cylinder 10, so that there is a gap 14 between the outer wall of the rib module 20 and the inner wall of the die cylinder 10. This gap 14 is used to accommodate the previously coated fiber material. Then, the fiber material is coated on the side of the rib module 20 away from the die cylinder 10 and connected with the fiber material on the inner wall of the die cylinder 10. In this way, an integral annular rib plate can be formed through the rib module 20. The rib plate is directly integrally formed with part of the inner wall of the die cylinder 10 without subsequent assembly or separate manufacturing, resulting in higher processing efficiency and better product quality.

[0021] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
