[0033] In order to make the purpose, technical scheme and advantages of the embodiments of the present disclosure clearer, the technical scheme in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure. It should be noted that, in the absence of conflict, the embodiments in this application and the feature vectors in the embodiments can be arbitrarily combined with each other.

[0034] During the solidification molding and core pulling production process of hollow profiles, wall thickness tolerance problems are easily caused due to various factors. In order to adjust the wall thickness of the hollow profile, it is often necessary to remove the die plate and the core, and adjust the relative position of the die plate and the core to avoid the size error of the profile. This method is often time-consuming and labor-intensive, resulting in increased production loss rate and production cost, and low production efficiency and product yield.

[0035] To solve the above problems, the present invention provides a die plate assembly, a core pulling mold and a profile production equipment. By setting a first adjustment component and a second adjustment component in the die plate assembly, the position of the die plate is adjusted, thereby adjusting the wall thickness of the profile to be formed along the first direction and the second direction. This is beneficial to timely eliminate the wall thickness dimensional deviation caused by other factors in the profile production process, reduce production losses, and improve production efficiency and product yield.

[0036] According to an exemplary embodiment, Figure 1-Figure 2 As shown, an embodiment of the present disclosure provides a die plate assembly, which is used for core pulling of hollow profiles. The hollow profiles can be, for example, yarns, cloths, webbings, etc. impregnated with resin, which are subjected to photocuring and core pulling to form a photovoltaic frame. Of course, it can be understood that the technical solution of the embodiment of the present disclosure can also be applied to profile forming of other materials or processes, such as the curing of thermoplastic materials or thermosetting materials. This article only takes the method of core pulling by photocuring as an example for specific description.

[0037] The die plate assembly includes a die plate 10, a first adjustment assembly 11 and a second adjustment assembly 12. The die plate 10 is provided with at least one die opening 101 for a mold core 20 and a profile to be formed (not shown in the figure) to pass through. The mold core 20 passes through the hollow part of the profile to be formed. The first adjustment assembly 11 is used to adjust the thickness of the wall thickness of the profile to be formed along the first direction, and the second adjustment assembly 12 is used to adjust the thickness of the wall thickness of the profile to be formed along the second direction. By adjusting the die plate 10 to move in the first direction or the second direction, the distance between the edge of the die opening 101 and the edge of the mold core 20 along the first direction or the second direction can be changed, thereby changing the thickness of the wall thickness of the profile to be formed along the first direction or the second direction, so as to eliminate the problem of wall thickness tolerance caused by other links or factors in the production process through timely adjustment, improve production efficiency and product yield, and reduce production losses.

[0038] The moving direction of the mold core 20, the first direction, and the second direction are perpendicular to each other. Figure 2 Taking the orientation shown in as an example, the direction of travel of the mold core 20 is Figure 2 The Z direction shown in FIG. 1 is the first direction. Figure 2 The X direction is shown in Figure 2 In the Y direction shown in , the X direction, the Y direction and the Z direction are mutually perpendicular, and the first adjustment component 11 and the second adjustment component 12 can adjust the thickness of the upper, lower, left and right walls of the hollow profile formed by the solidification of the profile to be formed. It is worth noting that the travel direction, the first direction and the second direction of the mold core 20 can be mutually perpendicular and can be approximately perpendicular, that is, the angle between the two can be within the range of about 90°, for example, it can be 75° to 105°. When there is a certain deviation between the travel direction, the first direction and the second direction of the mold core 20 and 90°, it may have a certain impact on the shape of the final formed profile. Those skilled in the art can set or adjust it according to actual needs, and the embodiments of the present disclosure will not elaborate on this.

[0039] In some embodiments, Figure 2As shown, the first adjustment component 11 is used to adjust the die plate 10 to move in the first direction. The first adjustment component 11 includes a first adjustment plate 111 and a first adjustment member 112, the first adjustment plate 111 is used to be fixedly connected to the core-pulling mold, and the first adjustment member 112 is used to adjust the distance that the die plate 10 moves relative to the core-pulling mold in the first direction.

[0040] In one example, one end of the first adjusting member 112 is movably connected to the first adjusting plate 111, and the other end of the first adjusting member 112 is fixedly connected to the die plate 10. By moving the first adjusting member 112 in a direction close to or away from the first adjusting plate 111, the die plate 10 is driven to move, thereby adjusting the distance that the die plate 10 moves in the first direction. In another example, one end of the first adjusting member 112 is fixedly connected to the first adjusting plate 111, and the other end of the first adjusting member 112 abuts against the die plate 10. The length of the first adjusting member 112 extending out of the first adjusting plate 111 is adjustable to push the die plate 10 and adjust the distance that the die plate 10 moves in the first direction. The first adjusting member 112 can be, for example, a screw, a pull rod, a pull block, or other structure that facilitates adjustment of the length extending out of the first adjusting plate 111.

[0041] In one example, the die plate assembly further includes a connecting plate 102, a first side of the connecting plate 102 is connected to the die plate 10, a second side of the connecting plate 102 opposite to the first side is provided with a first mounting portion 1021, the first mounting portion 1021 extends along a first direction, and a second mounting portion 341 cooperating with the first mounting portion 1021 is provided on the core-pulling mold, so that the die plate 10 can be slidably connected to the core-pulling mold along the first direction. Among them, one of the first mounting portion 1021 and the second mounting portion 341 is a slide groove, and the other is a slider. Of course, it can be understood that the first mounting portion 1021 and the second mounting portion 341 can also adopt other structures that can slide relative to each other, and the embodiment of the present disclosure does not impose too many restrictions on the specific forms of the first mounting portion 1021 and the second mounting portion 341.

[0042] In some embodiments, Figure 2 As shown, the second adjustment assembly 12 is used to adjust the die plate 10 to move in the second direction. The second adjustment assembly 12 includes a second adjustment plate 121 and a second adjustment member 122, the second adjustment plate 121 is used to be fixedly connected to the core-pulling mold, and the second adjustment member 122 is used to adjust the distance that the die plate 10 moves relative to the core-pulling mold in the second direction.

[0043] In one example, one end of the second adjusting member 122 is movably connected to the second adjusting plate 121, and the other end of the second adjusting member 122 is fixedly connected to the die plate 10. By moving the second adjusting member 122 in a direction close to or away from the second adjusting plate 121, the die plate 10 is driven to move, thereby adjusting the distance that the die plate 10 moves in the second direction. In another example, one end of the second adjusting member 122 is fixedly connected to the second adjusting plate 121, and the other end of the second adjusting member 122 abuts against the die plate 10. The length of the second adjusting member 122 extending out of the second adjusting plate 121 is adjustable to push the die plate 10 and adjust the distance that the die plate 10 moves in the second direction. The second adjusting member 122 can be, for example, a screw, a pull rod, a pull block, or other structure that facilitates adjustment of the length extending out of the second adjusting plate 121.

[0044] In one example, the second side of the connecting plate 102 is connected to the core-pulling mold, and the first side of the connecting plate 102 is provided with a third mounting portion 1022, and the third mounting portion 1022 extends along the second direction. The side of the die plate 10 close to the connecting plate 102 is provided with a fourth mounting portion 103, and the third mounting portion 1022 cooperates with the fourth mounting portion 103 to enable the die plate 10 and the core-pulling mold to be slidably connected along the second direction. Among them, one of the third mounting portion 1022 and the fourth mounting portion 103 is a slide groove, and the other is a slider. Of course, it can be understood that the third mounting portion 1022 and the fourth mounting portion 103 can also adopt other structures that can slide relative to each other. The embodiment of the present disclosure does not impose too many restrictions on the specific forms of the third mounting portion 1022 and the fourth mounting portion 103.

[0045] Among them, Figure 2 As shown, the slide groove can be a V-shaped groove, and the slider can be correspondingly set as a V-shaped block. Of course, it can be understood that the slide groove can also be a rectangular groove, a semicircular groove, etc. The cross-sectional shape of the slide groove can be adjusted according to actual needs, and the shape of the slider can correspond to the slide groove. The embodiments of the present disclosure do not impose too many restrictions on the shapes of the slide groove and the slider.

[0046] In the embodiment of the present disclosure, the position of the die plate is adjusted by setting a first adjustment component and a second adjustment component, thereby adjusting the wall thickness of the profile to be formed along the first direction and the second direction. This is beneficial to timely eliminate wall thickness dimensional deviations caused by other factors in the profile production process, reduce production losses, and improve production efficiency and product yield.

[0047] According to an exemplary embodiment, Figure 1-Figure 3As shown, the embodiment of the present disclosure provides a core-pulling mold, which is used for forming core-pulling of hollow profiles.

The first preformed plate 31 is used to position the raw materials of the yarn, ribbon, and cloth waiting for the profile to be formed, and the second preformed plate 32 is used to position and fix the raw materials of the profile to be formed. The number of the first preformed holes 311 can be greater than the number of the second preformed holes 322, so as to facilitate the profile to be formed to gradually form a preset shape from the first preformed plate 31 to the second preformed plate 32 when the yarn is threaded.

[0049] In some embodiments, the core-pulling mold can simultaneously perform the molding and core-pulling of multiple profiles to be molded. Figure 1 As shown, the core-pulling mold can simultaneously perform core-pulling of two profiles to be formed. Of course, it is understandable that the number of profiles to be formed can also continue to increase according to actual needs, and the embodiments of the present disclosure do not impose too many restrictions on this. The core-pulling mold includes a plurality of cores 20, a plurality of mounting holes 321 are provided on the second preformed plate 32, and a plurality of die openings 101 are provided on the die plate 10 of each die plate assembly.

Each core 20 passes through a mounting hole 321 and a corresponding die opening 101.

[0050] In some embodiments, the core-pulling mold further includes a base 33 and a fixing member 34. Figure 1 As shown, the first preformed plate 31, the second preformed plate 32, the die plate 10 and the fixing member 34 are all fastened to the base 33. The fastening connection method can be snap-on, plug-in, mortise and tenon connection, threaded connection, bonding, etc., or a combination of several of them can be used, for example, mortise and tenon connection and threaded connection can be used at the same time to improve the connection reliability. The embodiment of the present disclosure does not impose too many restrictions on the specific connection method, as long as the first preformed plate 31, the second preformed plate 32, the die plate 10 and the fixing member 34 can be fixed to the base 33.

[0051] In one example, the core-pulling mold includes a fixing member 34, and the core-pulling mold also includes two die plate assemblies, the fixing member 34 is tightly connected to the base 33, the connecting plate 102 of the die plate assembly is slidably connected to the fixing member, the two die plate assemblies are arranged opposite to each other, and the two die plate assemblies are respectively fixed on both sides of the fixing member 34 along the travel direction of the mold core 20. Among them, the fixing member 34 can be a cubic frame, or a block or plate structure with an opening, etc., as long as the mold core 20 and the profile to be formed can pass through, and the embodiment of the present disclosure does not impose too many restrictions on the shape of the fixing member.

[0052] In some embodiments, the core-pulling mold further includes a die extension 13, which is disposed on a side of the die plate assembly away from the core 20, and is used to extend into a light curing device for light curing, so that the profile to be formed forms a hollow profile.

[0053] In some embodiments, the shape of the die 101 can be designed and adjusted to obtain profiles with different cross-sectional shapes through solidification molding. Figure 4 As shown in the example, Figure 4 It is a schematic diagram of the cross-sectional shape of the profile after forming. Specifically, the profile can be a photovoltaic frame. The cross-section of the photovoltaic frame profile includes a hollow main body 41 and an extension portion 42 connected to the main body 41. A cavity is provided inside the main body 41 to ensure that the weight of the profile is reduced while having a certain structural strength. The extension portion 42 includes a first connection portion 421 and a second connection portion 422 that are connected. The first connection portion 421 is connected to the side wall of the main body 41 and extends in a direction away from the main body 41. The second connection portion 422 and the first connection portion 421 have an angle of nearly 90°, for example, it can be 70° to 110°. A accommodating space 423 is formed between the first connection portion 421, the second connection portion 422 and the main body 41, and the accommodating space 423 can be used for snap-fitting and installing a photovoltaic panel (not shown in the figure).
