[0026] When using the water expansion forming process to manufacture beams of different sizes, a mold needs to be developed for each size of the beam. The mold development time is long and the cost is high. The inventor wants to design a combined mold so that mold makers can reuse multiple straight mold segments 1, thereby reducing mold making time and cost and improving mold flexibility.

[0027] Embodiment 1

[0028] In a first aspect, the present application provides a mold, which includes multiple straight mold segments 1 and at least one curved mold segment 2, each straight mold segment 1 has a first cavity 11 extending in a straight line along a first direction A, and the first cavity 11 has an inlet 9 and an outlet 10 that are connected to each other; each curved mold segment 2 has a curved second cavity 21, and the second cavity 21 has an inlet 9 and an outlet 10 that are connected to each other; wherein the inlets 9 and outlets 10 of two adjacent straight mold segments 1, the inlets 9 and outlets 10 of two adjacent curved mold segments 2, and the inlets 9 or outlets 10 of two adjacent straight mold segments 1 are detachably connected with the outlet 10 or inlet 9 of the curved mold segment 2 through a fastening assembly 8, so that the multiple first cavities 11 of the multiple straight mold segments 1 and the second cavity 21 of at least one curved mold segment 2 are connected to form a cavity for compression molding.

[0029] Specifically, Figure 1As shown, the number of straight mold segments 1 and the number of curved mold segments 2 can be set according to actual needs, and the number of straight mold segments 1 and the number of curved mold segments 2 are not specifically limited here. The diameter of the first cavity 11 of each straight mold segment 1 and the second cavity 21 of each curved mold segment 2 can be set according to actual needs, and the shape of the cross section of the first cavity 11 and the second cavity 21 can be any shape, such as elliptical, circular, etc., and the shape of the cross section of the first cavity 11 and the second cavity 21 is not specifically limited here. In addition, the length of each first cavity 11 can be the same or different, and the length of each second cavity 21 can be the same or different. The inlet 9 and outlet 10 of two adjacent straight mold segments 1, the inlet 9 and outlet 10 of two adjacent curved mold segments 2, and the inlet 9 or outlet 10 of two adjacent straight mold segments 1 and the outlet 10 or inlet 9 of the curved mold segment 2 are detachably connected through a fastening assembly 8, and the fastening assembly 8 here can be specifically a bolt 7 connector, a snap connector, or a mortise and tenon connector.

[0030] The mold provided in the first aspect of the present application includes a plurality of straight mold segments 1 and at least one curved mold segment 2. The plurality of straight mold segments 1, the plurality of curved mold segments 2, and the straight mold segments 1 and the curved mold segments 2 are connected to each other in a portable and detachable manner through fastening components 8, so that flexible combinations can be achieved. Mold makers can connect a plurality of straight mold segments 1 in series according to needs to form a variety of straight modules with different length specifications. At the same time, they can also mix and match the straight mold segments 1 with the curved mold segments 2 to form mold cavities required to adapt to different shapes of beam bodies 14. In addition, the straight mold segments 1 are highly reusable. When the existing curved mold segments 2 are no longer suitable for the new beam product design, there is no need to replace all the mold segments. The reusable straight mold segments 1 are retained, and new curved mold segments 2 are customized for the new beam shape, and then the two are spliced ​​together. The mold separates the straight module from the curved module and divides the straight module into a plurality of straight mold sections 1, so that mold makers can flexibly combine them according to needs, shortening the mold R&D cycle, reducing the mold production cost, and improving the flexibility and resource utilization of the mold.

[0031] In some embodiments, each straight mold segment 1 and curved mold segment 2 includes an upper mold 12 and a lower mold 13 having a mold cavity 15. The upper mold 12 and the lower mold 13 are relatively arranged along a second direction B and are detachably connected by a fastening assembly 8, so that the mold cavity 15 of the upper mold 12 and the mold cavity 15 of the lower mold 13 are relatively and connected along the second direction B to form a first cavity 11 or a second cavity 21; wherein the second direction B is the radial direction of the first cavity 11 and the second cavity 21.

[0032] Specifically, Figure 1As shown, each straight mold segment 1 and curved mold segment 2 is composed of an upper mold 12 and a lower mold 13, both of which have a mold cavity 15. For each straight mold segment 1, its upper mold 12 and lower mold 13 are relatively placed along the second direction B. The mold cavity 15 of the upper mold 12 is precisely aligned with the mold cavity 15 of the lower mold 13 in the second direction B, and a detachable connection is achieved through a fastening component 8, where the fastening component 8 can specifically be a bolt 7 connector, a snap connector, or a mortise and tenon connector. When the fastening component 8 is connected, the mold cavity 15 of the upper mold 12 and the lower mold 13 can be tightly fitted and aligned to form a linear first cavity 11 for shaping the straight part of the target workpiece. Similarly, the upper mold 12 and the lower mold 13 of the curved mold segment 2 are also relatively arranged along the same second direction B, and a detachable connection is achieved through the same fastening component 8. In this case, after the mold cavities 15 of the upper mold 12 and the lower mold 13 are connected, a second cavity 21 with a certain bending angle will be formed to meet the molding requirements of the curved or turning parts of the target workpiece. In this way, both the straight mold segment 1 and the curved mold segment 2 can be flexibly spliced ​​and disassembled to meet the design requirements of products of different sizes and shapes, greatly improving the versatility and reuse rate of the mold.

[0033] In some embodiments, at least some of the straight mold segments 1 extend along the first direction A at different lengths.

[0034] Specifically, Figure 1 As shown, at least some of the straight mold segments 1 in the plurality of straight mold segments 1 have different lengths along the first direction A or each straight mold segment 1 has a different length along the first direction A. For example, there are 6 straight mold segments 1, and their lengths are 10 mm, 20 mm, 50 mm, 100 mm, 200 mm, and 500 mm, respectively, or there are 8 straight mold segments 1, and their lengths are 10 mm, 20 mm, 20 mm, 50 mm, 100 mm, 200 mm, 500 mm, and 500 mm, respectively. By providing straight mold segments 1 of different lengths, the number of splicing times can be reduced compared to a plurality of straight molds of the same length, the splicing interfaces of the overall structure can be reduced, and the strength and stability of the overall structure can be improved.

The distance that the edges of the protrusion 3 and the recessed portion 4 extend to the mold cavity 15 can be set according to actual needs, and the distance that the edges of the protrusion 3 and the recessed portion 4 extend to the mold cavity 15 is not limited here. The flange 6 of the upper mold 12 and the flange 6 of the lower mold 13 are provided with opposite screw holes, and the number of screw holes on each flange 6 can be set according to actual needs, and the number of screw holes on each flange 6 is not specifically limited here. By providing the protrusion 3 and the recess 4, the relative sliding between the upper mold 12 and the corresponding lower mold 13 can be limited, and the stability between the upper mold 12 and the lower mold 13 can be improved. In addition, the flange 6 can provide a stable contact surface to enhance the sealing performance when the upper mold 12 and the lower mold 13 are closed.

[0037] In some embodiments, the mold further includes a sealing plate 5 , and a sealing plate 5 is provided on both the side of the flange 6 of the upper mold 12 facing away from the lower mold 13 and the side of the flange 6 of the lower mold 13 facing away from the upper mold 12 , and the sealing plate 5 is fixed by bolts 7 .

[0038] Specifically, Figure 3 As shown, in order to further enhance the sealing effect, sealing plates 5 are respectively provided on the side of the flange 6 of the upper mold 12 away from the lower mold 13 and the side of the flange 6 of the lower mold 13 away from the upper mold 12. The thickness, size and shape of the sealing plate 5 can be set according to actual needs. The material of the sealing plate 5 can be rubber or other materials with good sealing properties. The material of the sealing plate 5 is not specifically limited here. The sealing plate 5 is provided with screw holes corresponding to the flange 6. The bolts 7 pass through the flange 6 of the upper mold 12 and the flange 6 of the lower mold 13 and pass through the corresponding sealing plate 5, so that the sealing plate 5 is tightly pressed against the surface of the flange 6 to form a tight sealing interface, which effectively prevents leakage of the mold in the working state.

[0039] In some embodiments, the fastening assembly 8 includes a plurality of slots 81, a plurality of connecting columns 82 and an adjusting pin 83, wherein the plurality of slots 81 are arranged at intervals along the axis of the cavity at the outlet 10 end of the straight mold segment 1 or the inlet 9 end of the straight mold segment 1 and the outlet 10 end of the curved mold segment 2 or the inlet 9 end of the curved mold segment 2; the plurality of connecting columns 82 extend along the first direction A and are arranged at intervals along the axis of the cavity at the inlet 9 end of the straight mold segment 1 or the outlet 10 end of the straight mold segment 1 and the inlet 9 end of the curved mold segment 2 or the outlet 10 end of the curved mold segment 2, the plurality of connecting columns 82 correspond to and are plugged into the plurality of slots 81 one by one, wherein the diameter of the slot 81 is greater than the diameter of the connecting column 82; each slot 81 corresponds to at least two adjusting pins 83, and at least two adjusting pins 83 are plugged into the slot 81 and are located between the slot 81 and the connecting column 82, so as to adjust the position of the connecting column 82 in the slot 81.

[0040] Specifically, Figure 2 As shown, a plurality of slots 81 are arranged at intervals along the axis of the cavity at the outlet 10 end of the straight mold segment 1 or the inlet 9 end of the straight mold segment 1 and the outlet 10 end of the curved mold segment 2 or the inlet 9 end of the curved mold segment 2, and the spacing distance between two adjacent slots 81 can be set according to actual needs. A plurality of connecting posts 82 extend along the first direction A and are arranged at intervals along the axis of the cavity at the inlet 9 end of the straight mold segment 1 or the outlet 10 end of the straight mold segment 1 and the inlet 9 end of the curved mold segment 2 or the outlet 10 end of the curved mold segment 2, and the spacing distance between two adjacent connecting posts 82 is the same as the spacing distance between two adjacent slots 81. The number of slots 81 and connecting posts 82 can be set according to actual needs, and the shape of the connecting posts 82 can be any shape, such as cylindrical, conical, etc. The number of slots 81 and connecting posts 82 is equal, and the shapes of the slots 81 and connecting posts 82 are adapted. The connecting posts 82 can be integrally formed with the straight mold segment 1 or the curved mold segment 2. In order to achieve the fine-tuning function, the diameter of the slot 81 is made larger than the diameter of the connecting column 82, and a certain gap is reserved so that fine-tuning can be performed by inserting different numbers or thicknesses of adjustment pins 83. The number of adjustment pins 83 in each slot 81 can be selected according to actual needs, and the adjustment pins 83 can be set as tapered pins with gradually decreasing diameters for adjustment. This structure of the fastening assembly 8 not only enhances the convenience and flexibility of mold assembly, but also greatly improves the overall precision and work efficiency of the mold, and reduces product quality problems caused by the accumulation of errors between mold sections.

[0041] In some embodiments, the fastening assembly 8 includes a plurality of mounting holes and a plurality of pins, wherein the plurality of mounting holes are arranged at intervals along the axis of the cavity at the outlet 10 end of the straight mold segment 1 or the inlet 9 end of the straight mold segment 1 and the outlet 10 end of the curved mold segment 2 or the inlet 9 end of the curved mold segment 2; the plurality of pins extend along the first direction A and are arranged at intervals along the axis of the cavity at the inlet 9 end of the straight mold segment 1 or the outlet 10 end of the straight mold segment 1 and the inlet 9 end of the curved mold segment 2 or the outlet 10 end of the curved mold segment 2, and the plurality of pins correspond to the plurality of mounting holes one by one and are plugged in.

[0042] Specifically, Figure 1-Figure 3 As shown, a plurality of mounting holes are arranged at intervals along the axis of the cavity at the outlet 10 end of the straight mold section 1 or the inlet 9 end of the straight mold section 1 and the outlet 10 end of the curved mold section 2 or the inlet 9 end of the curved mold section 2, and the spacing distance between two adjacent mounting holes can be set according to actual needs; a plurality of pins extend along the first direction A and are arranged at intervals along the axis of the cavity at the inlet 9 end of the straight mold section 1 or the outlet 10 end of the straight mold section 1 and the inlet 9 end of the curved mold section 2 or the outlet 10 end of the curved mold section 2, and the spacing distance between two adjacent pins is the same as the distance between two adjacent mounting holes.

Through the plug-in cooperation between the pins and the mounting holes, precise alignment and fixation between the straight mold segment 1 and the curved mold segment 2, between the straight mold segment 1 and the straight mold segment 1, and between the curved mold segment 2 and the curved mold segment 2 are achieved, ensuring the structural stability and precision requirements of the entire mold during the working process.

[0043] In some embodiments, the mold further comprises a sealing strip, which is arranged along the axis of the cavity at the inlet 9 end and / or outlet 10 end of the straight mold section 1 and the inlet 9 end and / or outlet 10 end of the curved mold section 2.

[0044] Specifically, Figure 1-Figure 3As shown, in order to further improve the overall sealing performance of the mold and prevent material overflow, the mold also includes a sealing strip (not shown in the figure). The sealing strip can be set at both ends of the straight mold segment 1 at the same time, or it can be selected to be set at only one end of the straight mold segment 1 (inlet 9 or outlet 10) for a surrounding sealing according to actual needs. Similarly, for the curved mold segment 2, the sealing strip can be set at both ends of the curved mold segment 2 at the same time, or it can be selected to be set at only one end of the curved mold segment 2 (inlet 9 or outlet 10) for a surrounding sealing according to actual needs. By setting the sealing strip at the intersection between two adjacent straight mold segments 1, the intersection between two adjacent curved mold segments 2, and the intersection between the adjacent straight mold segments 1 and the curved mold segments 2, it is possible to block leakage that may occur during the molding process. In addition, the sealing strip is usually made of materials with high elasticity, high temperature resistance, wear resistance, and excellent anti-aging performance. It can not only fit the mold segment interface tightly, but also adapt to the deformation of the mold during the opening and closing process, thereby maintaining good sealing performance for a long time.

[0045] In some embodiments, a protective cover is further included, which has a receiving groove adapted to the connecting column 82 . The protective cover is detachably connected to one end of the connecting column 82 of the straight mold segment 1 or the curved mold segment 2 and corresponds to the connecting column 82 to accommodate the connecting column 82 .

[0046] Specifically, Figure 1-Figure 3 As shown, in order to prevent the connection column 82 that is not docked with other slots 81 from being accidentally hit and causing breakage after assembly, the mold is also provided with a protective cover (not shown in the figure). The protective cover is designed with a receiving groove that matches the shape and size of the connection column 82, which can just accommodate the undocking connection column 82 therein, thereby providing additional protection. The protective cover is connected in a detachable manner, and the detachable connection method here can be specifically connected by bolts 7 connectors, snaps and other connectors. It can be flexibly installed on the end of the straight mold section 1 or the curved mold section 2 with the connection column 82 as needed to ensure that the exposed connection column 82 can be fully protected when the mold is not in working state or during transportation to avoid damage caused by collision or misoperation.
