Description

Technical Field

[0001] This utility model relates to the field of boat hull forming mold technology, specifically a new type of high-speed boat hull forming mold. Background Technology

[0002] As a type of water transportation vehicle with high speed and maneuverability, high-speed boats require hulls that meet core requirements such as high strength, resistance to wind and waves, and streamlined design. Hull molding molds are key equipment for achieving these requirements. These molds are typically female molds, using high-strength, heat-resistant, and tough materials such as fiberglass as the main base material. Through processes such as hand lay-up molding combined with resin and reinforcing materials, the hull is cured and formed. The surface accuracy and structural rigidity of these molds directly determine the appearance quality and sailing performance of the high-speed boat, making them an indispensable core tooling equipment in the production and manufacturing of high-speed boats.

[0003] Based on the above, the inventors have discovered the following problems: Most current high-speed boat hull forming molds are of an integral design, with the mold length fixed during manufacturing, only suitable for hull forming needs of a single length. Because the market demand for high-speed boat lengths is diverse (e.g., 6 meters, 8 meters, 12 meters, etc.), companies need to design and manufacture a complete set of molds for each length specification. This not only significantly increases mold production costs and extends the production cycle but also occupies a large amount of storage space, making it difficult to meet the needs of flexible and efficient production.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a new type of high-speed boat hull forming mold in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this invention is to provide a novel high-speed boat hull forming mold to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A novel high-speed boat hull forming mold includes a master mold comprising several separate modules arranged in a straight line, each module having a different length; a pair of positioning rods are mounted on the outer wall of one end of each of the separate modules, and a pair of positioning holes are provided on the outer wall of the other end of each of the separate modules, with the inner wall of the positioning hole and the outer wall of the positioning rod having a clearance fit; connecting members are respectively provided on the outer sides of two adjacent separate modules.

[0008] Furthermore, the outer wall of the positioning rod is provided with a silicone anti-slip layer, and a pair of positioning holes are respectively arranged opposite to a pair of positioning rods.

[0009] The beneficial effects of adopting the above-mentioned further solution are that the gap fit between the positioning hole and the positioning rod enables the initial accurate positioning of adjacent sub-modules, ensuring the alignment of the profiles after splicing; the silicone anti-slip layer increases the friction between the positioning rod and the inner wall of the positioning hole, reducing the relative sliding of the sub-modules due to vibration or force after splicing, improving positioning stability, and at the same time, the silicone material has a certain elasticity, which can buffer the impact of collisions during splicing.

[0010] Furthermore, a first magnet is embedded in the outer wall of one end of each of the several split modules, and a second magnet is embedded in the outer wall of the other end of each of the several split modules. The first magnet and the second magnet have opposite magnetic poles, and adjacent first magnets and second magnets are magnetically connected.

[0011] The beneficial effects of adopting the above-mentioned further solution are that, since the first magnet and the second magnet have opposite magnetic poles and are magnetically connected, the magnetic attraction force can be used to achieve rapid pre-fixation of adjacent split modules; at the same time, the magnetic connection can help eliminate the gaps between the splicing surfaces of the split modules, enhance the tightness of the initial connection, and provide guiding adsorption force during the installation process, simplifying the docking process of the split modules.

[0012] Furthermore, the connector includes a connector seat, which is installed on the outer side wall of the split module at the end where the positioning hole is provided. An elastic strip is provided inside the connector seat, which is installed on the outer side wall of the split module at the end where the positioning rod is provided. A slot is provided on the connector seat, and a wedge-shaped block is engaged in the slot. The wedge-shaped block is installed on one side of the outer wall of one of the side arms of the elastic strip.

[0013] The beneficial effect of adopting the above-mentioned further solution is that, through the interlocking structure of the wedge-shaped card block and the card slot, the adjacent split modules are locked by utilizing the wedge self-locking principle. With the elastic pre-tightening force of the elastic strip, the splicing gap is further eliminated and the connection rigidity is improved. By squeezing the side arm on which the elastic strip is equipped with the wedge-shaped card block, the locking and unlocking of the split modules can be completed quickly, which is suitable for production scenarios with frequent specification changes.

[0014] Furthermore, one end of the connecting seat is open, the elastic strip is U-shaped, and the elastic strip and wedge-shaped locking block are integrally formed. The elastic strip and wedge-shaped locking block are composed of a stainless steel inner layer and a silicone rubber outer layer. The beneficial effects of adopting the above-mentioned further solution are that the open-shaped connecting seat facilitates the insertion and removal of the elastic strip and wedge-shaped locking block; the U-shaped elastic strip can adapt to minor errors during splicing through its own deformation, enhancing the locking and sealing performance; the stainless steel inner layer ensures structural strength and avoids long-term deformation of the elastic strip under stress; the silicone rubber outer layer improves wear resistance and elastic recovery; and the integrally formed structure ensures the firm connection between the wedge-shaped locking block and the elastic strip, extending the service life of the connector.

[0015] Furthermore, the wedge-shaped block has a first screw hole inside, and the top and bottom surfaces of the connecting seat both have second screw holes inside. Bolts are threadedly connected between the first screw hole and a pair of second screw holes. The beneficial effect of this further solution is that, based on the engagement of the wedge-shaped block and the slot, secondary fixation is achieved through the rigid locking of the bolts. This distributes the stress of the assembled modular components to the bolts and the wedge-shaped structure, significantly improving the connection strength and preventing loosening of the mold due to resin pressure or vibration during the molding process, ensuring the stability of the assembly and the overall rigidity of the mold.

[0016] Furthermore, the inner walls of several of the modular components are coated with a release agent, and the modular components are composed of a fiberglass substrate and a polyurethane foam core layer.

[0017] The beneficial effects of adopting the above-mentioned further solutions are that the release agent can reduce the adhesion force between the hull and the inner wall of the mold after the hull is formed, making it easier to demold and ensuring the smoothness of the hull surface; the fiberglass substrate has high strength and rigidity, can withstand molding pressure and maintain the accuracy of the profile, the polyurethane foam core layer greatly reduces the weight of the module, making it easy to handle and disassemble, and the composite structure takes into account both strength and lightweight requirements.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: The new high-speed boat hull forming mold achieves preliminary accurate positioning of adjacent sub-modules through the gap fit between the positioning hole and the positioning rod, ensuring alignment of the profile after splicing; since the first and second magnetic pieces have opposite magnetic poles and are magnetically connected, the magnetic attraction force is used to achieve rapid pre-fixation of adjacent sub-modules; through the interlocking structure of the wedge-shaped card block and the card slot, the wedge self-locking principle is used to lock the adjacent sub-modules, and with the elastic pre-tightening force of the elastic strip, the splicing gap is further eliminated and the connection rigidity is improved; through the combination and splicing of sub-modules of different lengths, it can flexibly adapt to the forming requirements of various specifications of high-speed boat hulls such as 6 meters, 8 meters, and 12 meters, without the need to manufacture a complete set of molds for each length, which greatly reduces the mold production cost, improves the mold reuse rate, and shortens the switching production cycle of different specifications of boat hulls.

[0025] 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.

[0026] Please see Figures 1-5 This utility model provides a technical solution: a novel high-speed boat hull forming mold, including a mother mold 1, which includes several separate modules 11 arranged in a straight line, and the lengths of the separate modules 11 are different; a pair of positioning rods 14 are installed on the outer wall of one end of each of the separate modules 11, and a pair of positioning holes are provided on the outer wall of the other end of each of the separate modules 11, with the inner wall of the positioning hole and the outer wall of the positioning rod 14 in clearance fit; connecting parts 2 are respectively provided on the outer sides of two adjacent separate modules 11; a silicone anti-slip layer is provided on the outer wall of the positioning rod 14; a pair of positioning holes are respectively arranged opposite to a pair of positioning rods 14; a first magnet piece 12 is embedded in the outer wall of one end of each of the separate modules 11; and the outer wall of the other end of each of the separate modules 11... Each module 11 is embedded with a second magnet piece 13. The magnetic poles of the first magnet piece 12 and the second magnet piece 13 are opposite, and adjacent first magnet pieces 12 and second magnet pieces 13 are magnetically connected. The gap fit between the positioning hole and the positioning rod 14 realizes the initial accurate positioning of adjacent split modules 11, ensuring the alignment of the profile after splicing. Since the magnetic poles of the first magnet piece 12 and the second magnet piece 13 are opposite and magnetically connected, the magnetic attraction force is used to realize the rapid pre-fixation of adjacent split modules 11. With the help of the connector 2 to capture the combination and splicing of split modules 11 of different lengths, it can flexibly adapt to the forming requirements of various specifications of high-speed boat hulls such as 6 meters, 8 meters, and 12 meters. There is no need to manufacture a complete set of molds for each length, which greatly reduces the mold production cost, improves the mold reuse rate, and shortens the production cycle of switching between different specifications of boat hulls.

[0027] 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.

[0028] Please see Figures 1-5 This utility model provides a technical solution: the connector 2 includes a connector 21, which is installed on the outer wall of the split module 11 at one end where a positioning hole is provided. An elastic strip 22 is provided inside the connector 21 and is installed on the outer wall of the split module 11 at one end where a positioning rod 14 is provided. A slot 24 is provided on the connector 21, and a wedge block 23 is engaged within the slot 24. The wedge block 23 is installed on one side of the outer wall of one of the side arms of the elastic strip 22. One end of the connector 21 is open. The elastic strip 22 is U-shaped and integrally formed with the wedge block 23. The elastic strip 22 and the wedge block 23 are composed of a stainless steel inner layer and a silicone rubber outer layer. The wedge block 23 has a first screw hole 25 inside. The top and bottom surfaces of the connecting seat 21 are both provided with second screw holes 26. Bolts 27 are threadedly connected between the first screw hole 25 and a pair of second screw holes 26. The inner walls of several separate modules 11 are coated with a release agent. Several separate modules 11 are composed of a fiberglass substrate and a polyurethane foam core layer. The wedge block 23 and the slot 24 engage to lock adjacent modular modules 11 using the wedge self-locking principle. Combined with the elastic pre-tightening force of the elastic strip 22, this further eliminates splicing gaps and enhances connection rigidity. Based on the engagement of the wedge block 23 and the slot 24, secondary fixing is achieved through the rigid locking of the bolt 27. This distributes the force of the modular module 11 splicing to the bolt 27 and the wedge structure, significantly improving connection strength and preventing loosening of the mold due to resin pressure or vibration during molding, ensuring splicing stability and overall mold rigidity. The side arm with the wedge block 23 installed on the elastic strip 22 can quickly lock and unlock the modular module 11, adapting to production scenarios with frequent specification changes. The release agent reduces the adhesion between the hull and the mold inner wall after molding, facilitating smooth demolding and ensuring a smooth hull surface. The fiberglass substrate possesses high strength and rigidity, capable of withstanding molding pressure and maintaining profile accuracy. The polyurethane foam core significantly reduces module weight, facilitating handling and disassembly. The composite structure balances strength and lightweight requirements.

[0029] Specifically, the working principle of this new type of high-speed boat hull forming mold is as follows: During use, the positioning rod 14 of an adjacent modular module 11 is aligned with the positioning hole of another module and slowly inserted. The silicone anti-slip layer on the outer wall of the positioning rod 14 adheres to the inner wall of the positioning hole, achieving initial guiding and positioning. Simultaneously, the first magnet 12 and the second magnet 13 at the end of the module automatically attract each other due to their opposite magnetic poles, completing pre-fixation and reducing splicing gaps. The elastic strip 22 is pushed, causing its U-shaped structure to insert along the open connecting seat 21 until the wedge block 23 engages with the slot 24 of the connecting seat 21, initially locking the module using the wedge self-locking principle. At this time, the silicone rubber outer layer of the elastic strip 22 is compressed, generating elastic pre-tightening force, further eliminating splicing gaps, while the stainless steel inner layer ensures the structure does not deform. The bolt 27 passes through the second screw hole 26 of the connecting seat 21 and the first screw hole 25 of the wedge block 23 and is tightened to achieve rigid locking, distributing the stress of the assembly to the bolt 27 and the wedge structure, ensuring that the mold does not loosen during resin injection and curing; at this time, the basic structure length of the mother mold 1 is 12 meters; then resin and reinforcing materials are laid into the assembled mother mold 1, and the release agent on the inner wall of the split module 11 is used to reduce adhesion; after the hull has cured and formed, the bolt 27 is unscrewed, and the side arm of the elastic strip 22 is squeezed to make the wedge block 23 disengage from the slot 24, and the magnetically attached module can be separated to take out the hull; if other lengths of hull need to be produced, the above steps are repeated to replace the corresponding split module 11 combination, without the need to readjust the basic structure of the mold, which greatly improves the switching efficiency.

[0030] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. Furthermore, since this application is mainly used to protect mechanical devices, the control methods and circuit connections will not be explained in detail in this application.
