Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to aid in understanding the invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are merely for describing exemplary embodiments of the invention. However, the invention can be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0034] Figure 1 A schematic diagram of the molding tooling is provided for an embodiment of this application, wherein... Figure 1 The second molding component 300 and the second working plate 102 are not installed or connected. Figure 2 This application provides a structural schematic diagram of the first molded part 200 and the second molded part 300 for embodiments of the present application. Figure 3 Cross-sectional views of a first molded part 200 and a second molded part 300 are provided for embodiments of this application.

[0035] like Figure 1 As shown, a molding fixture for composite column segments is disclosed. The molding fixture includes a frame 100, a first molding component 200, a second molding component 300, and an adhesive guiding part 400, wherein:

[0036] The frame 100 is fixedly provided with a first working plate 101 and is also movably provided with a second working plate 102 that can move closer to or further away from the first working plate 101. The frame 100 provides a working base, and by controlling the movement of the second working plate 102 relative to the first working plate 101, it can maintain a stable and reliable relative base in a complex working environment, thereby reducing errors caused by environmental factors during the assembly process and improving assembly accuracy and operational reliability.

[0037] Furthermore, depending on the structural configuration of the second working plate 102 driven on the frame 100, the first working plate 101 and the second working plate 102 can be arranged to work close to each other or far apart from each other.

[0038] like Figure 2 and Figure 3 As shown, the first molding part 200 is fixed on the first working plate 101, and the inner side of the first molding part 200 has a molding inner wall 201 of composite material. The top of the first molding part 200 is provided with an assembly hole 202 and the bottom is provided with a bottom hole 203. The first molding part 200 is fixed on the first working plate 101. The first molding part 200 can be disassembled and assembled through a detachable connector. When molding composite material column segments of different specifications, the first molding part 200 can be replaced to achieve a higher applicability. The molding inner wall 201 provided on the first molding part 200 provides surface support and supports the outer wall of the pre-molded product. After curing, it keeps the external surface of the final product in line with the preset requirements.

[0039] like Figure 2 and Figure 3 As shown, the second molding part 300 is fixed on the second working plate 102, and the outer side of the second molding part 300 has a molding outer wall 301 of composite material. The bottom of the second molding part 300 is provided with a positioning plate 302 that can cooperate with the bottom hole 203, so as to form a molding space for accommodating the pre-molded product by surrounding the first molding part 200 and the second molding part 300. The second molding part 300 can be disassembled and assembled by a detachable connector. When molding composite material column segments of different specifications, the second molding part 300 can be replaced to achieve a higher applicability. The molding outer wall 301 provided on the second molding part 300 provides surface support and supports the inner wall of the pre-molded product. After curing, it maintains the internal surface of the final product and the second molding part 300 to meet the preset matching requirements.

[0040] like Figure 1 As shown, during assembly, the second molding part 300 moves synchronously with the second working plate 102, and as the second molding part 300 moves closer to the first molding part 200, it can extend into the assembly hole 202. As the second molding part 300 continues to move, the positioning plate 302 at one end of the second molding part 300 moves into the bottom hole 203 at the bottom of the first molding part 200, thus completing the assembly. In this state, the positioning plate 302, the first molding part 200, and the second molding part 300 enclose a molding space for accommodating the pre-molded product.

[0041] like Figure 2 and Figure 3As shown, the adhesive guiding part 400 is disposed on the positioning plate 302. The adhesive guiding part 400 has an adhesive guiding cone surface 401 on the side facing the molding inner wall 201. The outer diameter of the adhesive guiding cone surface 401 on the side closer to the first working plate 101 is smaller than the outer diameter on the other side. When the second molding part 300 moves with the second working plate 102 close to the first working plate 101, there is an adhesive retention gap between the adhesive guiding cone surface 401 and the inner wall of the pre-molded product.

[0042] like Figure 2 and Figure 3 As shown, as the adhesive guiding part 400 moves closer to the first working plate 101, the adhesive guiding part 400 and the positioning plate 302 move together toward the bottom hole 203. The smaller end of the adhesive guiding cone 401 enters the assembly hole 202 first, and under the constraint of the adhesive guiding cone 401, the unevenly distributed adhesive is guided, and the positioning plate 302 is protected to directly scrape off the adhesive on the inner wall of the preformed product, improving the reliability of the assembly. Moreover, the more stable distribution of the adhesive can improve the reliability of the finished product.

[0043] In an optional embodiment, the working principle of the molding fixture in this application is as follows: The molding fixture includes a frame 100, a first molding component 200, a second molding component 300, and a guide portion 400. The frame 100 is provided with a first working plate 101 and a second working plate 102 that can be close to or away from the first working plate 101. The first molding component 200 and the second molding component 300 are respectively fixed on the first working plate 101 and the second working plate 102. The outer side of the first molding component 200 has a molding inner wall 201 of composite material, and the inner side of the second molding component 300 has a molding outer wall 301 of composite material. The bottom of the first molding component 200 is provided with a bottom hole 203, and the bottom of the second molding component 300 is provided with a positioning plate 302 that can cooperate with the bottom hole 203. The guide portion 400 is provided on the positioning plate 302. The side of the guide portion 400 facing the molding inner wall 201 is provided with a guide cone surface 401. The outer diameter of the side of surface 401 closest to the first working plate 101 is smaller than the outer diameter of the other side. During the assembly process, the second working plate 102 moves back and forth relative to the first working plate 101 to maintain the accuracy of the relative movement between the first molding part 200 and the second molding part 300. Specifically, during the assembly operation, there is a glue gap between the glue-guiding cone surface 401 and the inner wall of the pre-molded product until the positioning plate 302, the first molding part 200, and the second molding part 300 enclose and form a molding space for accommodating the pre-molded product. The pre-molded product is placed inside the first molding part 200. After the glue is applied, when the glue-guiding part 400 moves with the second molding part 300, it completes the uniform scraping of the glue layer on the inner wall of the pre-molded product, avoiding glue accumulation or scraping by the assembly operation with deviation, maintaining a uniform and reliable bonding effect, and improving the convenience and accuracy of operation by reducing the degree of manual intervention.

[0044] like Figure 2 and Figure 3 As shown, in an optional embodiment, a connecting frame 500 is provided between the second molding part 300 and the second working plate 102. The connecting frame 500 is detachably connected to the second molding part 300 and the second working plate 102 respectively. The connecting frame 500 facilitates the installation of the second molding part 300. In particular, the second working plate 102 is an active moving structure relative to the first working plate 101. The second molding part 300 can first be arranged on the first working plate 101 by moving as a whole with the first molding part 200, and then arranged on the second working plate 102 or the second molding part 300 by the connecting frame 500. Then the connecting frame is fixed on the other one. In the process of arranging the second molding part 300 on the second working plate 102, the installation difficulty is reduced, and the safety of the molded outer wall 301 on the second molding part 300 is maintained to prevent collision damage.

[0045] like Figure 2 and Figure 3 As shown, in an optional embodiment, the connecting frame 500 includes an upper connecting plate 501 for connecting the second working plate 102 and a lower connecting plate 502 for connecting the second molded part 300, and a plurality of connecting posts 503 are provided between the upper connecting plate 501 and the lower connecting plate 502 to provide an observation gap between the upper connecting plate 501 and the lower connecting plate 502.

[0046] like Figure 2 and Figure 3 As shown, under the action of multiple connecting posts 503, after the upper connecting plate 501 is fixedly connected to the second working plate 102 and the lower connecting plate 502 is fixedly connected to the second molding part 300, the connecting posts 503 are positioned between the upper and lower connecting plates, maintaining a gap of the length of the connecting post 503 between them. This ensures that the second molding part 300 can always be stably connected to the second working plate 102, and provides a controllable observation gap between the second molding part 300 and the second working plate 102. This allows the operator to observe the relative positional relationship and assembly progress as needed during the assembly process of the second molding part 300 and the first molding part 200, resulting in greater flexibility.

[0047] like Figure 2 and Figure 3 As shown, in an optional embodiment, a limiting post 601 is fixedly provided on the connecting frame 500, and the other end of the limiting post 601 is detachably fixed on the first molded part 200 to restrict the second molded part 300 from continuing to move closer to the first molded part 200.

[0048] One end of the limiting post 601 is detachably fixed to the connecting frame 500. The length of the limiting post 601 can be determined according to the relative positional relationship between the first molded part 200 and the second molded part 300 after assembly. When the first molded part 200 and the second molded part 300 are fitted together, the limiting post 601 abuts against the connecting frame 500 and the first molded part 200, and forms a movement barrier between the first molded part 200 and the second molded part 300, thus maintaining a certain distance between them. The minimum relative positional relationship ensures that the assembly gap between the first molded part 200 and the second molded part 300 can maintain a set distance, preventing the first molded part 200 from getting too close to the second molded part 300, maintaining the relative positional relationship between the inner molded wall 201 and the outer molded wall 301, improving the reliability of the assembly process, avoiding operational damage between the first molded part 200 and the second molded part 300 due to misoperation, improving the relative positional stability of the first molded part 200 and the second molded part 300 during the curing process, and improving the curing effect.

[0049] After the limiting post 601 moves to the target position following the second molding part 300, it completes the connection and fixing operation with the first molding part 200 to complete the configuration of the limiting post 601. After the curing operation is completed, the limiting post 601 and the first molding part 200 can be separated to carry out subsequent operations.

[0050] like Figure 2 and Figure 3 As shown, in an optional embodiment, the molding fixture further includes a guide rod 602 and a positioning seat 603. One of the guide rod 602 and the positioning seat 603 is fixedly connected to the connecting frame 500, and the other is fixedly connected to the first molding part 200. When the second molding part 300 moves close to the first molding part 200, the guide rod 602 and the positioning seat 603 cooperate to guide the second molding part 300 to cooperate with the first molding part 200 in a set direction.

[0051] like Figure 2 and Figure 3 As shown, during the relative fitting of the second molded part 300 and the first molded part 200, as the second molded part 300 and the first molded part 200 move closer to each other, the guide rod 602 and the positioning seat 603 also move closer to each other. This maintains the relative movement of the second molded part 300. Through the cooperation and guidance of the guide rod 602 and the positioning seat 603, a constraint is formed on the relative movement of the second molded part 300, improving the fitting accuracy of the second molded part 300 and the first molded part 200. Furthermore, the matching process of the guide rod 602 and the positioning seat 603 forms a corresponding positioning guide, eliminating a certain degree of assembly error.

[0052] After the guide rod 602 is placed on the connecting frame 500, the positioning seat 603 is fixed on the first molded part 200, or after the guide rod 602 is placed on the first molded part 200, the positioning seat 603 is fixed on the connecting frame 500.

[0053] like Figure 2 As shown, in an optional embodiment, the first molded part 200 includes a plurality of enclosure portions 203, and the plurality of enclosure portions 203 are detachably connected to each other, which facilitates disassembly and assembly and improves the convenience of assembly.

[0054] like Figure 2 As shown, in an optional embodiment, the outer wall of the first molded part 200 is provided with staggered reinforcing ribs 204 to improve the overall structural strength of the second molded part 300 and maintain a more stable support effect during the curing process.

[0055] In an optional embodiment, the first molded part 200 is provided with an observation hole 205, which improves the convenience of observation and also achieves the effect of lightweighting the second molded part 300, making it easier to carry out operations.

[0056] like Figure 1 As shown, in an optional embodiment, the forming fixture further includes a drive unit 103 arranged on the frame 100. The drive unit 103 is connected to the second working plate 102 via a traction unit 104 to traction the second working plate 102 to move back and forth.

[0057] The drive unit 103 can be a drive motor, and the traction unit 104 can be a wire rope.

[0058] Based on the same inventive concept, this application also provides a molding method for composite material segments, using the molding tooling described above, the molding method comprising the following steps:

[0059] Between the first working plate 101 and the second working plate 102, a first molding component 200 and a second molding component 300 are installed. The second molding component 300 and the first molding component 200 are then fitted together until the molding space meets the molding requirements.

[0060] Take a pre-formed product and place it inside the first molded part 200, and apply adhesive to the inner wall of the pre-formed product and the outer wall 301 of the molded part respectively;

[0061] The second molding part 300 is moved toward the first molding part 200 and adhesive is guided onto the inner wall of the pre-formed product through the adhesive guiding part 400 until the positioning plate 302 engages with the bottom hole 203.

[0062] Maintain the relative positions of the first molded part 200 and the second molded part 300, and allow them to cure at room temperature.

[0063] After removing the first molding part 200, the second molding part 300 and the second working plate 102 are separated to obtain the finished product.
