Description

Technical Field

[0001] This utility model relates to the field of molds, specifically to a wooden cylindrical mold. Background Technology

[0002] PAN-based, adhesive-based, and bitumen-based rigid felts are important industrial materials with wide applications in aerospace, automotive manufacturing, and construction. In the production process of PAN-based, adhesive-based, and bitumen-based rigid felts, molds are key forming tools, and their quality and performance directly affect product quality and production efficiency.

[0003] Currently, cylindrical molds are widely used in industrial production for manufacturing various circular components such as pipes and well shafts. However, existing molds for PAN-based, adhesive-based, and bitumen-based rigid felt materials have significant drawbacks. Traditional molds are typically made entirely of Q235 steel, resulting in excessive weight, generally reaching around 1.5 tons. This excessive weight not only complicates the assembly process but also significantly increases the difficulty and labor intensity of product manufacturing. Furthermore, the high material cost of all-steel molds significantly increases production costs, hindering cost reduction and efficiency improvement for enterprises. Therefore, there is an urgent need to develop a lightweight, low-cost, easy-to-operate mold for PAN-based, adhesive-based, and bitumen-based rigid felt materials that can guarantee product quality. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a wooden cylindrical mold, which addresses the problem that the excessive weight of existing molds not only makes the mold assembly process complicated and difficult, but also greatly increases the difficulty and labor intensity of product manufacturing, as well as the high material cost of all-steel molds, leading to increased production costs.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a wooden cylindrical mold is provided, including an inner mold and circular side plates arranged on both sides of the inner mold. The inner mold includes a support plate. The support plates are spaced at the same distance and are arranged in three sets. A steel pipe is arranged at the axial position of the support plate. The two ends of the steel pipe pass through the axial center of the circular side plate and extend outward. A first clamp is arranged on both sides of the support plate at the connection between the steel pipe and the support plate. A support rod is arranged through the support plate around the circumference of the axial center. A second clamp is arranged on both sides of the support plate at the connection between the support rod and the support plate. Support bars are arranged around the outer periphery of the support plate.

[0006] The support plate, support rod, and support strip are all made of wood.

[0007] Furthermore, both ends of the support strip pass through the circular side plate.

[0008] Furthermore, eight sets of square tubes are arranged radially on the outer side of the circular side plate. The square tubes are fixed to the outer side of the circular side plate by the first bolt, and the ends of the square tubes pass through the support strip.

[0009] Furthermore, a disc is provided on the outside of the square tube, and the disc is fixed to the outside of the square tube by a second bolt.

[0010] Furthermore, the disc shaft passes through a steel pipe, and the steel pipe is mounted on the disc via an L-shaped connecting block.

[0011] Furthermore, the circular side plate is provided with insertion holes on its outer periphery and radially, and the insertion holes are equipped with insertion tubes.

[0012] Furthermore, kraft paper is adhered to the outer periphery of the support strip.

[0013] The beneficial effects of this utility model are as follows:

[0014] By replacing part of the Q235 steel with wood, the overall weight of the mold is significantly reduced. Compared to traditional all-steel molds weighing approximately 1.5 tons, the weight of this new wooden cylindrical mold is greatly reduced, facilitating assembly and handling. Simultaneously, wood is far less expensive than Q235 steel, significantly lowering manufacturing costs. Furthermore, wood is easy to process, allowing for flexible adjustment of size and shape as needed, improving the mold's adaptability and practicality. The rational layout design of the support plate, support rods, and support bars ensures sufficient strength and stability during use, meeting the requirements for producing PAN-based rigid felt.

Detailed Implementation

[0022] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] like Figures 1 to 5 As shown, a wooden cylindrical mold includes an inner mold 1 and circular side plates 2 disposed on both sides of the inner mold 1. The inner mold 1 includes support plates 101, which are spaced evenly and arranged in three sets. A steel pipe 4 is disposed at the axial center of the support plate 101, with both ends of the steel pipe 4 passing through the axial center of the circular side plate 2 and extending outward. At the connection between the steel pipe 4 and the support plate 101, first clamps 104 are disposed on both sides of the support plate 101. Figure 2 and Figure 3 As shown, the first clamp 104 is fixed to the steel pipe 4 to enhance the connection stability between the steel pipe 4 and the support plate 101. Support rods 103 are installed around the support plate 101 around the axis. Second clamps 102 are installed on both sides of the support plate 101 at the connection points between the support rods 103 and the support plate 101. Figure 3 As shown, the second clamp 102 is fixed to the support rod 103 to strengthen the connection between the support rod 103 and the support plate 101. Support bars 105 are arranged around the outer periphery of the support plate 101, forming a cylindrical structure. Figure 5 As shown. The support plate 101, support rod 103 and support bar 105 are all made of wood. This material choice gives the mold good processing performance and a certain strength.

[0024] The two ends of the support bar 105 pass through the circular side plate 2 respectively. This design allows the support bar 105 to be fixed at both ends by the circular side plate 2, which enhances the structural stability of the entire mold.

[0025] Eight sets of square tubes 3 are radially arranged on the outer side of the circular side plate 2. The square tubes 3 are fixed to the outer side of the circular side plate 2 by the first bolt 301. Figure 1 and Figure 4 As shown, the end of the square tube 3 passes through the support strip 105. This design allows the square tube 3 to provide additional support to the support strip 105, preventing the support strip 105 from deforming during use.

[0026] A disc 5 is provided on the outside of the square tube 3. The disc 5 is fixed to the outside of the square tube 3 by a second bolt 502. Figure 4 As shown. The arrangement of disc 5 further enhances the structural stability of the entire mold, preventing shaking or deformation during use.

[0027] The axis of disk 5 passes through steel pipe 4, and steel pipe 4 is mounted on disk 5 via L-shaped connecting block 501. Figure 4 As shown. The design of the L-shaped connecting block 501 forms a stable connection between the steel pipe 4 and the disc 5, ensuring that the entire mold maintains good coaxiality during use.

[0028] The circular side plate 2 has insertion holes 201 extending through its outer circumference and radially, and insertion holes 201 are fitted with insertion tubes 7, such as... Figure 1 As shown. The design of the insertion hole 201 and the insertion tube 7 allows the mold to add support or fixing points at different locations as needed, improving the mold's adaptability and flexibility.

[0029] The outer periphery of the support strip 105 is bonded with kraft paper 6, such as Figure 1 As shown. The bonding of kraft paper 6 makes the mold surface smoother, which is beneficial for demolding the molded product. It also protects the surface of the wooden support strip 105 and extends the service life of the mold.

[0030] In use, with the steel pipe 4 as the central axis, three sets of support discs 101 are evenly distributed on the steel pipe 4. Support rods 103 penetrate the support discs 101 to provide radial support, and support bars 105 are arranged on the mold surface to form a cylindrical structure. Circular side plates 2 are fixed at both ends, and the overall structure is further strengthened by square tubes 3 and discs 5. This design gives the mold good strength and stability, and is suitable for molding various cylindrical products.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
