[0068] This application discloses an adjustable forming mold and a wire surface coating forming method, which includes some or all of the technical features of the following embodiments; that is, the adjustable forming mold includes some or all of the following structures. In one embodiment of this application, an adjustable forming mold includes a first adjustable forming mold, a second adjustable forming mold, a mold base, a fixing member, and a forming mold piece assembly. The first adjustable forming mold and the second adjustable forming mold are respectively fixed to the mold base by the fixing member, and the positions of the first adjustable forming mold and the second adjustable forming mold are adjusted by the adjusting groove of the mold base in conjunction with the fixing member, so as to adjust the width of the cavity between the first adjustable forming mold and the second adjustable forming mold. The first adjustable forming mold and the second adjustable forming mold cooperate to form a film winding position in the cavity, so that the film is rolled up at the film winding position to cover the surface of the wire. The first adjustable forming mold and the second adjustable forming mold also cooperate to form a discharge end, the discharge end is connected to the end of the cavity, and the forming mold piece assembly is fixed to the mold base at the discharge end. The aforementioned adjustable forming mold, through its adjustable forming structure design, has a wide applicability of forming mold pieces. It can be easily adjusted to form wires of different specifications. On the one hand, it provides a universal forming mold that can be applied to the forming of various specifications of wires without the need for custom-made forming molds, thus improving production efficiency and facilitating modified production. On the other hand, it has good versatility, thus reducing production costs, and requires relatively less material, thus reducing material management costs.

[0069] The following is combined with Figures 1 to 16 The adjustable forming mold and the wire surface coating forming method are described in detail.

[0070] In one embodiment, an adjustable forming die, such as Figure 1 As shown, it includes a first adjustable forming mold 110, a second adjustable forming mold 120, a mold base 130, a fixing member 140, and a forming mold piece assembly 160; combined with Figure 2 The first adjustable forming mold 110 and the second adjustable forming mold 120 cooperate to modulate the film 300 to cover the surface of the wire 200, thereby obtaining the wire 200 covered with the film 300, referred to as the coated wire, which is then formed and output through the forming mold assembly 160.

[0071] Specifically, the first adjustable forming mold 110 is fixed to the mold base 130 by the fixing member 140, and the second adjustable forming mold 120 is also fixed to the mold base 130 by the fixing member 140. The first adjustable forming mold 110 and the second adjustable forming mold 120 can be fixed to the mold base 130 by the same fixing member 140, or they can be fixed to the mold base 130 by different fixing members 140.

[0072] Furthermore, the first adjustable forming mold 110 and the second adjustable forming mold 120 are respectively adjusted by the adjusting groove 131 of the mold base 130 in conjunction with the fixing member 140, so that the positions of the first adjustable forming mold 110 and the second adjustable forming mold 120 can be adjusted. That is, the position of the first adjustable forming mold 110 can be adjusted within the range defined by the adjusting groove 131, that is, the position of the first adjustable forming mold 110 fixed on the mold base 130 can be adjusted. Similarly, the position of the second adjustable forming mold 120 can also be adjusted within the range defined by the adjusting groove 131. The adjusting groove 131, in conjunction with the fixing member 140, is used to adjust the width of the cavity 102 between the first adjustable forming mold 110 and the second adjustable forming mold 120. In each embodiment, the width corresponds to the width of the wire 200 covered by the film 300, and can also be understood as the width of the coated wire.

[0073] In one embodiment, the first adjustable forming mold 110 and the second adjustable forming mold 120 are respectively fixed to the mold base 130 by screws via the fixing member 140, such as Figure 2 As shown, the fixing member 140 includes fixing screws 141 and nuts 142. The first adjustable forming mold 110 is fixed to the mold base 130 by fixing screws 141 and nuts 142. Similarly, the second adjustable forming mold 120 is also fixed to the mold base 130 by fixing screws 141 and nuts 142. In other embodiments, the first adjustable forming mold 110 and the second adjustable forming mold 120 can also be fixed to the mold base 130 by the fixing member 140 in a snap-fit ​​or plug-in manner.

[0074] In various embodiments, the number of adjustment grooves 131 may be one or two, but typically two adjustment grooves 131 are selected. In one embodiment, the number of adjustment grooves 131 is a pair, and the pair of adjustment grooves 131 are arranged symmetrically along an axis of symmetry, the direction of which is parallel to the conveying direction of the wire 200 and the film 300; in another embodiment, the axis of symmetry is located on the bisecting plane of the mold base 130. This structural design facilitates the rapid and accurate adjustment of the positions of the first adjustable forming mold 110 and the second adjustable forming mold 120.

[0075] In one embodiment, such as Figure 3 and Figure 4 As shown, the mold base 130 has an arc-shaped upper film material surface 132, which is used to transport the film 300 into the cavity 102, and the upper film material surface 132 is located below the position where the adjustable forming mold inputs the wire 200. This structural design creates an arc-shaped film feeding direction 310 for the arc-shaped upper film material surface 132. Correspondingly, combined with... Figure 1 and Figure 2 The wire 200 is input into the adjustable forming mold from above the film 300, thus creating a process environment in which the wire 200 and the film 300 are simultaneously input into the adjustable forming mold. Specifically, the film 300 enters the mold base 130 from below, and is rolled up by the first adjustable forming mold 110 and the second adjustable forming mold 120 to cover the surface of the linearly advancing wire 200, forming a ring-shaped seal. It then passes through the forming mold plate group 160, in which the spacing plate 170 and the line width plate 180 achieve the purpose of evenly dividing and forming the coated wire.

[0076] Continue to combine Figure 1 and Figure 2 In one embodiment, the adjustable forming die is further provided with transverse guide posts 190 on the die base 130. The extension direction of the transverse guide posts 190 is perpendicular to the conveying direction of the wire 200 and the film 300, that is, perpendicular to the wire feeding direction 210 of the wire 200. The transverse guide posts 190 are used to guide the wire 200 and / or the film 300 to the discharge end 104. Further, in one embodiment, the number of transverse guide posts 190 is at least two, one of which is disposed adjacent to the forming die assembly 160 or adjacent to the discharge end 104. This structural design allows the transverse guide posts 190 to assist in conveying the wire 200 and the film 300 in the wire feeding direction 210, and to assist in conveying the wire 200 covered with the film 300, ensuring conveying force to ensure that the coated wire is output from the forming die assembly 160.

[0077] In one embodiment, such as Figure 5 As shown, the first adjustable forming mold 110 and the second adjustable forming mold 120 have a gap as the cavity 102. The width of the cavity 102 is D1. As mentioned above, the width D1 of the cavity 102 is defined by the first adjustable forming mold 110 and the second adjustable forming mold 120 being fixed to the mold base 130 by the fixing member 140, respectively.

[0078] Similarly, in one embodiment, such as Figure 6 As shown, the first adjustable forming mold 110 and the second adjustable forming mold 120 have a gap as the cavity 102, and the width of the cavity 102 is D2. D2 is greater than D1 to accommodate wider wires 200.

[0079] In each embodiment, such as Figure 5 and Figure 6 As shown, the first adjustable forming mold 110 and the second adjustable forming mold 120 cooperate in the cavity 102 to form a film winding position 103, so that the film 300 is rolled up at the film winding position 103 to cover the surface of the wire 200. Rolling up the film 300 to cover the surface of the wire 200 can usually be achieved by conventional molds, i.e., conventional technology, and is not the inventive point of this application. One of the inventive points of this application is that the width of the cavity 102 between the first adjustable forming mold 110 and the second adjustable forming mold 120 is adjustable, thereby adapting to the coating process of wires of various widths.

[0080] In each embodiment, such as Figure 5 and Figure 6 As shown, the first adjustable forming mold 110 and the second adjustable forming mold 120 also cooperate to form a discharge end 104. That is, the discharge end 104 is formed in the cooperation structure of the first adjustable forming mold 110 and the second adjustable forming mold 120. The discharge end 104 is connected to the end of the cavity 102. That is, the wire covered with the film leaves the adjustable forming mold or its mold base 130 from the discharge end 104. The discharge end 104 is also located on the mold base 130. That is, the discharge end 104 is located at the position of the feed end 101 of the mold base 130 away from the cavity 102.

[0081] In one embodiment, such as Figure 5 and Figure 6 As shown, the first adjustable forming mold 110 includes an integrally formed first forming mold body 111, a first forming mold feed section 112, a first forming mold film winding section 113, and a first end section 114; the second adjustable forming mold 120 includes an integrally formed second forming mold body 121, a second forming mold feed section 122, a second forming mold film winding section 123, and a second end section 124; the first forming mold body 111 and the second forming mold body 121 cooperate to form the cavity 102; combined with Figure 7 The first forming die feeding section 112 and the second forming die feeding section 122 cooperate to form a feeding end 101 communicating with the cavity 102, and the feeding end 101 has a converging shape; the first forming die winding section 113 and the second forming die winding section 123 cooperate in the cavity 102 to form the winding position 103; combined Figure 8The first end portion 114 and the second end portion 124 cooperate to form the discharge end 104.

[0082] In various embodiments, the forming die assembly 160 is fixed to the die base 130 at the discharge end 104. Further, in one embodiment, as... Figure 2 and Figure 3 As shown, the adjustable forming mold also includes a clamping member 150, which fixes the forming die assembly 160 to the mold base 130 at the discharge end 104. This is because the forming die assembly 160 needs to adapt to the forming of wires of various specifications. Therefore, when adjusting the width of the cavity 102 between the first adjustable forming mold 110 and the second adjustable forming mold 120, it is very likely that the forming die assembly 160 will also need to be adjusted simultaneously, for example, adjusting the wire groove 161 and its spacing portion 162 of the forming die assembly 160. In this state, the forming die assembly 160 needs to be fixed to the mold base 130. In contrast, traditional dedicated forming molds, i.e., fixed molds, use a fixed mold outlet, so there is no need to adjust the forming die assembly 160, nor is it necessary to use the clamping member 150 to fix the forming die assembly 160 to the mold base 130 at the discharge end 104.

[0083] In one embodiment, the forming die assembly 160 is provided with opposing adjustable spacing components, which are used to evenly divide and form the wire 200 covered with the film 300. The number of adjustable spacing components is one pair, and the pair of adjustable spacing components are arranged opposite each other, that is, the pair of adjustable spacing components are arranged symmetrically, and the forming die assembly 160 is formed by mold closing as a mold outlet.

[0084] Furthermore, in one embodiment, such as Figure 9 and Figure 10 As shown, the adjustable spacing component is used to adjust the wire groove 161 and its spacing portion 162 of the forming die set 160 according to the target specifications, so that the adjustable forming die can be easily adjusted for forming wires of different specifications. Further, in one embodiment, the adjustable spacing component includes multiple sets of preset structural components, each set corresponding to a different target specification, to adjust the wire groove 161 and its spacing portion 162 of the forming die set 160 according to the target specifications. This structural design replaces the traditional die replacement with replacing the forming die set 160 or its adjustable spacing component, while simultaneously adjusting the width of the cavity 102 between the first adjustable forming die 110 and the second adjustable forming die 120.

[0085] In one embodiment, such as Figure 8 and Figure 9As shown, the adjustable spacing component includes regularly arranged spacing pieces 170 and linewidth pieces 180. The spacing pieces 170 are used to space adjacent strands of the wire 200, and the linewidth pieces 180 are used to limit the width of the strands of the wire 200. Further, in one embodiment, the spacing pieces 170 and the linewidth pieces 180 are spaced apart, with one linewidth piece 180 between two spacing pieces 170 and one spacing piece 170 between two linewidth pieces 180. This facilitates the accurate formation of the wire groove 161 and its spacing portion 162 of the forming mold assembly 160. This design, by employing detachable and combinable spacing pieces and linewidth pieces—that is, sheet-like structures—achieves combined application, thus providing an adjustable-width mold. This allows the use of a single mold to accommodate all products, enabling film forming of all products without the need for new molds, effectively reducing costs.

[0086] Further, in one embodiment, the spacing pieces 170 and the line width pieces 180 have the same mounting specifications, so that each of the spacing pieces 170 and each of the line width pieces 180 is fixed together by the same clamping member 150 or mounting member, that is, the spacing pieces 170 and each of the line width pieces 180 are mutually fixed. In one embodiment, the adjustable forming mold further includes a clamping member 150, which fixes the adjustable spacing assembly on the mold base 130 and aligns it with the discharge end 104 to maintain the conveying direction of the wire 200. Further, in one embodiment, the spacing pieces 170 and the line width pieces 180 have the same screw holes, and the clamping member 150 is a bolt. In one embodiment, the spacing pieces 170 and the line width pieces 180 have slots, and the clamping member 150 is a fastener. This structural design replaces the traditional mold changing with the selection of each of the adjustable spacing pieces 170 and each of the line width pieces 180 of the adjustable spacing component, while simultaneously adjusting the width of the cavity 102 between the first adjustable forming mold 110 and the second adjustable forming mold 120. Therefore, it can be applied to the forming of various specifications of wire without the need for specially customized forming molds, thus improving production efficiency and facilitating modified production.

[0087] Furthermore, in one embodiment, the spacing piece 170 and the linewidth piece 180 have the same sliding groove. The spacing piece 170 and the linewidth piece 180 are respectively slidably disposed on the mold base 130 and fixed by the clamping member 150. This design facilitates the quick and accurate assembly of the adjustable spacing component, ensuring that the adjustable spacing component is aligned with the discharge end 104, thereby ensuring accurate mold exit and guaranteeing production yield.

[0088] In one embodiment, such as Figure 11 and Figure 12 As shown, the spacer 170 includes an integrally formed spacer body 171 and a spacer end 173; as Figure 13 and Figure 14 As shown, the linewidth strip 180 includes an integrally formed linewidth strip body 181 and a linewidth strip end 183; combined with Figure 15 The end of the spacing piece 173 protrudes beyond the end of the linewidth piece 183, in combination with Figure 10 The two opposing ends of the spacing pieces 173 are used to form a spacing portion 162 in the forming mold piece group 160, and the opposing ends of the line width pieces 183 are used to form a line groove 161 in the forming mold piece group 160.

[0089] In one embodiment, such as Figure 11 and Figure 12 As shown, the spacer 170 also includes a spacer top 172 located on and integrally formed with the spacer body 171, the spacer top 172 being wider than the spacer body 171 to make the spacer 170 generally T-shaped. In one embodiment, as... Figure 13 and Figure 14 As shown, the linewidth sheet 180 also includes a linewidth sheet top 182 located on and integrally formed with the linewidth sheet body 181. The linewidth sheet top 182 is wider than the linewidth sheet body 181, making the linewidth sheet 180 generally T-shaped. Further, in one embodiment, the length of the spacing sheet 170 is greater than the length of the linewidth sheet 180, and the spacing sheet top 172 is flush with the linewidth sheet top 182, so that the spacing sheet end 173 protrudes beyond the linewidth sheet end 183, so that the two opposing spacing sheet ends 173 form a spacing portion 162 in the forming die assembly 160, and the opposing linewidth sheet ends 183 form a groove 161 in the forming die assembly 160. This structural design facilitates the rapid and accurate arrangement of the spacing pieces 170 and the line width pieces 180 to form the adjustable spacing assembly, and forms the spacing portion 162 and the line groove 161 separated by the spacing portion 162 on the forming mold piece group 160.

[0090] To facilitate wire forming, in one embodiment, such as Figure 11 As shown, the end 173 of the spacer plate has a gradient region 174. The end of the gradient region 174 adjacent to the discharge end 104 is larger than the end away from the discharge end 104, so as to facilitate the gradual narrowing deformation. This allows the wire 200 covered with the film 300 to be slowly pressed into the small hole from the large hole, achieving uniform forming while ensuring the tightness of the wire coating.

[0091] Specifically, the arrangement of the spacing plates 170 and the linewidth plates 180 is as follows: Figure 9 and Figure 10 As shown, the comparison between the spacing plate 170 and the linewidth plate 180 is as follows: Figure 15 As shown, the top 172 of the spacing piece and the top 182 of the line width piece can have the same shape and size or different; the end 173 of the spacing piece protrudes from the end 183 of the line width piece, thereby forming a spacer 162 in the forming mold assembly 160 by two opposing spacing pieces 170, and forming a groove 161 in the forming mold assembly 160 by two opposing line width pieces 180.

[0092] In one embodiment, a wire surface coating forming method is implemented based on the adjustable forming mold described in any embodiment, that is, the wire surface coating forming method employs the adjustable forming mold described in any embodiment. In one embodiment, a wire surface coating forming method is as follows: Figure 16 As shown, it includes the following steps: S100, adjusting the forming mold group according to the wire coating requirements, and determining the positions of the first adjustable forming mold and the second adjustable forming mold on the mold base; S200, fixing the first adjustable forming mold and the second adjustable forming mold to the mold base respectively by fixing members, and forming a cavity, a film winding position and a discharge end, wherein the film winding position is located in the cavity; S300, fixing the forming mold group to the mold base at the discharge end; S400, simultaneously inputting the film and the wire, so that the film is rolled up at the film winding position to cover the surface of the wire, and at the discharge end, the forming mold group evenly divides the wire covered with the film into shape. This design, combined with an adjustable forming structure, makes the forming die set 160 widely applicable. It can be easily adjusted to form wires of different specifications. On the one hand, it provides a universal forming die that can be applied to the forming of various specifications of wires without the need for special custom forming dies, thus improving production efficiency and facilitating modified production. On the other hand, it has good versatility, thus reducing production costs and requiring less material, thereby reducing material management costs.
