[0003] Patent Document 1: Japanese Patent Application Publication No. 2024-31506 (Figure 10). Summary of the Invention The problem that the invention aims to solve

[0004] When molding resin parts and other molded articles as described above are formed using, for example, openable upper and lower molds, the molded article is sometimes left in the upper mold, even though the design is intended to keep it in the lower mold. This phenomenon is known as "mold sticking." If mold sticking occurs, removing the molded article becomes extremely difficult, leading to a decrease in productivity, and therefore countermeasures are needed.

[0009] [Description of embodiments of this disclosure] First, embodiments of this disclosure will be listed and described. (1) The wiring component of this disclosure includes an electric wire and a molded portion covering the outer peripheral surface of the electric wire. Parting lines are provided at two locations on the outer peripheral surface of the molded portion. When the molded portion is imaginarily divided into a first portion and a second portion via an imaginary plane including the parting lines at the two locations, the first portion does not have an undercut shape relative to a demolding direction orthogonal to the imaginary plane, and the second portion has an undercut shape relative to the demolding direction.

[0010] When forming the wiring component, a first mold corresponding to the first part and a second mold corresponding to the second part are used. Here, the molded product as the wiring component is required to remain in the second mold (the mold from which the molded product is to be removed) after mold opening and to detach from the first mold. In this respect, according to the structure described in (1) above, the first part does not have an undercut shape relative to the demolding direction, while the second part has an undercut shape relative to the demolding direction, thus enabling a reliable formation where the first part detaches from the first mold and the second part remains in the second mold. As a result, the wiring component as the molded product can be removed from the second mold without difficulty, thereby improving productivity.

[0011] (2) In the wiring component described in (1) above, preferably, the undercut shape is formed by a peripheral surface extending on the outer peripheral surface of the second part in a direction intersecting the demolding direction. Therefore, an inverted shape can be formed without applying a special shape to the second part.

[0012] (3) In the wiring component described in (2) above, preferably, the outer periphery shape of the cross section of the molding part along the demolding direction is circular, and the outer periphery surface of the second part is an arc shape that includes the circumferential part and has the parting lines at two locations as the two circumferential ends. The outer perimeter of the second part does not contain any special shape, so it has a wider range of applications and can be versatile.

[0013] (4) In the wiring component described in (1) above, preferably, the undercut shape is formed by a protrusion that protrudes from the outer periphery of the second part in a direction intersecting the demolding direction. Therefore, by adjusting the shape, size, and angle of the protrusion, the demolding resistance during demolding of the second part can be set to an appropriate value.

[0014] (5) In the wiring component described in (4) above, preferably, the protrusion is disposed close to the parting line. Therefore, it is possible to avoid excessive demolding resistance during the second demolding process.

[0015] (6) In the wiring component described in (1) above, preferably, the undercut shape is formed by an undercut recess that extends inside the second part in a direction intersecting the demolding direction and opens on the outer peripheral surface of the second part. Since the inverted shape is provided as an inverted recess inside the second part, it is possible to prevent the outer periphery of the second part and even the wiring components from becoming larger.

[0016] (7) In the wiring component described in (6) above, preferably, the molding portion has a non-overturned recess that extends inside the first portion along the demolding direction and opens on the outer peripheral surface of the first portion, wherein the bottom surfaces of the overturned recess and the non-overturned recess are each formed by the outer peripheral surface of the wire. When forming the wiring component, a die is used to press the wire as an insert. As the die is pulled out, a recess is formed in the molding section. Here, the recess can be an undercut recess or a non-undercut recess. By using the recess formed during the pulling out of the die as both an undercut recess and a non-undercut recess, it is unnecessary to make the undercut recess and non-undercut recess separate into dedicated sections that only form undercut and non-undercut shapes.

[0017] (8) In any of the wiring components described in (1) to (7) above, preferably, the molded part is a sheath. This wiring component can prevent water from seeping between the wire and the sheath, thus making it suitable for environments requiring waterproofing. For example, by applying this wiring component to automotive wiring harnesses, improvements in wiring workability and usability can be achieved.

[0018] [Details of the embodiments disclosed herein] Specific examples of this disclosure will now be described with reference to the accompanying drawings. Furthermore, the invention is not limited to these examples, but is illustrated by the claims and is intended to include all modifications of the same meaning and scope as the claims.

[0019] <Implementation Method 1> The wiring component 10 of Embodiment 1 of this disclosure is configured, for example, as a wiring harness laid in a vehicle. Figure 1 and Figure 2 As shown, the wiring component 10 includes a wire 20 and a molded portion 30 covering the outer peripheral surface of the wire 20. In this embodiment 1, the wire 20 is as follows: Figure 2 As shown, this is a coated wire in which the conductor 21, which is composed of core wires, is covered by insulating resin 22. The insulating resin 22 is made of materials such as vinyl chloride or olefin resin. For example, the wire 20 is configured such that the outer periphery of the cross-section (hereinafter referred to as the "cross section") cut in a direction orthogonal to the axial direction is circular.

[0020] The molding portion 30 is integrally formed on the outer peripheral surface of the wire 20 by molding. By integrally forming the molding portion 30 on the outer peripheral surface of the wire 20, gaps that may form between the molding portion 30 and the wire 20 can be eliminated or reduced, thereby suppressing water seepage from the gaps.

[0021] The molding part 30 is exemplified as a sheath 30A. Sheath 30A is made of a material capable of achieving integration with the wire 20, namely a thermoplastic elastomer such as vinyl chloride, polyolefin, or polyurethane. The shape of sheath 30A is not particularly limited; as shown here... Figure 1 and Figure 2 As shown, the device is configured to have a main body 31 extending axially and a pair of expanded diameter portions 32 extending radially outward from both ends of the main body 31 along its axial direction. The main body 31 covers the middle portion of the wire 20 along its axial direction. The cross-section of both the main body 31 and the expanded diameter portions 32 is circular, specifically, a perfect circle.

[0022] When forming the sheath 30A, a first mold 80 is used as the upper mold and a second mold 90 is used as the lower mold (details not shown, see reference). Figure 2 The first mold 80 and the second mold 90 can open and close to each other. Here, the first mold 80 is configured as a movable mold, and the second mold 90 is configured as a fixed mold.

[0023] On the dividing surfaces 65 of the first mold 80 and the second mold 90, as Figure 3 Only the first mold 80 is shown, which has a sheath forming cavity 61 and a wire passage groove 62. The sheath forming cavity 61 has a shape corresponding to the outer peripheral shape of the sheath 30A, and is formed in the first mold 80 and the second mold 90 respectively with a curved concave cross-section. The wire passage groove 62 has a groove shape on both sides of the sheath forming cavity 61 in the axial direction to hold the wire 20, and is also formed in the first mold 80 and the second mold 90 respectively with a curved concave cross-section.

[0024] like Figure 1As shown, the wiring component 10 has a parting line 33 extending axially. In this embodiment 1, the parting line 33 is disposed at an offset position above (on one side) the center in the height direction of the sheath 30A (radial direction, demolding direction of the first mold 80 and the second mold 90). Specifically, as... Figure 2 As shown, the parting line 33 is disposed within the height range between the center of the wire 20 and the upper end of the wire 20, overlapping the wire 20 in the height direction. The parting line 33 is disposed at two circumferentially spaced locations on the outer peripheral surface of the sheath 30A, corresponding to the aforementioned dividing surface 65.

[0025] like Figure 2 As shown, when the sheath 30A is imaginarily divided in the height direction into an upper first portion 35 and a lower second portion 36 via an imaginary plane 34 (an imaginary straight line connecting the two parting lines 33 in cross-section) including the parting lines 33 at two points on the outer peripheral surface, the outer peripheral length of the cross-section of the second portion 36 is greater than the outer peripheral length of the cross-section of the first portion 35. In the case of this embodiment 1, since the cross-section of the outer peripheral shape of the sheath 30A is circular, the outer peripheral shape of the cross-section of the second portion 36 is configured as a major arc, and the outer peripheral shape of the cross-section of the first portion 35 is configured as a minor arc.

[0026] As described above, the outer peripheral surface of the second portion 36 is formed by an outer peripheral length exceeding half the circumference of the sheath 30A. The two circumferential ends of the outer peripheral surface of the second portion 36 form a pair of peripheral facets 37 extending arcuately from the center of the sheath 30A towards the parting line 33. Each peripheral facet 37 is formed along a direction intersecting the demolding directions of the first mold 80 and the second mold 90, thus becoming an undercut during mold opening. Therefore, the second portion 36 has an undercut shape through each peripheral facet 37.

[0027] On the other hand, the outer periphery of the first part 35 is composed of a periphery length that is less than half the circumference of the sheath 30A. The first part 35 as a whole does not have an undercut shape that intersects with the demolding directions of the first mold 80 and the second mold 90.

[0028] Next, the manufacturing method of the wiring component 10 will be described. With the first mold 80 and the second mold 90 open, the wire 20 is placed in the wire through slot 62 of the second mold 90, and the first mold 80 is closed relative to the second mold 90. The wire 20 is held by the wire through slots 62 of the first mold 80 and the second mold 90, and a sheath forming cavity 61 is defined and formed between the first mold 80 and the second mold 90. Next, molten material (here, thermoplastic elastomer) is injected into the sheath forming cavity 61 through a gate (not shown). After the material solidifies, the first mold 80 is opened, and the wiring component 10, as a molded product, is removed.

[0029] In the above description, the first portion 35 of the sheath 30A is formed by the sheath forming cavity 61 of the first mold 80. The second portion 36 of the sheath 30A is formed by the sheath forming cavity 61 of the second mold 90. The first portion 35 as a whole does not have an undercut shape. Therefore, when the mold is opened, the first portion 35 can be easily demolded from the first mold 80. On the other hand, the second portion 36 has an undercut shape through the peripheral surfaces 37. Therefore, when the mold is opened, the peripheral surfaces 37, which are undercuts, generate demolding resistance, and the second portion 36 can remain in the second mold 90. As a result, the wiring component 10, as a molded product, always remains in the second mold 90, and the wiring component 10 can be easily removed from the second mold 90.

[0030] As explained above, the wiring component 10 of this embodiment 1 includes a wire 20 and a molding portion 30 covering the outer peripheral surface of the wire 20. Parting lines 33 are provided at two locations on the outer peripheral surface of the molding portion 30. When the molding portion 30 is imaginarily divided into a first portion 35 and a second portion 36 via an imaginary plane 34 including the parting lines 33 at both locations, the first portion 35 does not have an undercut shape relative to the demolding direction orthogonal to the imaginary plane 34, while the second portion 36 has an undercut shape relative to the demolding direction.

[0031] Since the first part 35 does not have an undercut shape relative to the demolding direction, while the second part 36 does have an undercut shape relative to the demolding direction, it is possible to reliably achieve a state where the first part 35 detaches from the first mold 80 and the second part 36 remains in the second mold 90. As a result, the wiring component 10, as a molded product, can be removed from the second mold 90 without difficulty, thereby improving productivity.

[0032] In this embodiment 1, the undercut shape is formed by a peripheral surface 37 extending on the outer peripheral surface of the second portion 36 in a direction intersecting the demolding direction. Therefore, the undercut shape can be formed without applying a special shape to the second portion 36.

[0033] In particular, in the case of Embodiment 1, the outer periphery of the cross-section (cross section) of the molding portion 30 along the demolding direction is circular, and the outer periphery of the second portion 36 is an arc shape including the circumferential portion 37 and with the parting lines 33 at two points as the circumferential ends. Accordingly, the outer periphery of the second portion 36 does not contain any particular shape, so the wiring component 10 has a wider range of applications and can be versatile.

[0034] The wiring component 10 disclosed herein has a molded portion 30 configured as a sheath 30A, thereby preventing water from seeping between the wire 20 and the sheath 30A, and thus can be suitably used in environments requiring waterproofing. Furthermore, by applying the wiring component 10 to automotive wiring harnesses, for example, improvements in wiring workability and usability can be achieved.

[0035] <Implementation Method 2> use Figure 4 and Figure 5 The wiring component 10 of Embodiment 2 of this disclosure will be described. The wiring component 10 of Embodiment 2 differs from that of Embodiment 1 in the position of the parting line 33 and the undercut shape of the second portion 36. The undercut shape of the second portion 36 is formed by a protrusion 38 protruding from the outer peripheral surface of the second portion 36. The fact that the molded portion 30 is a sheath 30B and that the sheath 30B has a main body portion 31 and a pair of expanded diameter portions 32 is the same as in Embodiment 1.

[0036] In this embodiment 2, the parting line 33 is located at the center of the height direction of the sheath 30B (radial direction, demolding direction of the first mold 80 and the second mold 90). Specifically, the parting line 33 is located at the same height as the center of the wire 20.

[0037] like Figure 5 As shown, when the sheath 30B is imaginarily divided in the height direction into an upper part 35 and a lower part 36 via an imaginary plane 34 containing parting lines 33 at two points on the outer periphery, the first part 35 and the second part 36, except for the protrusion 38 of the second part 36, are configured as symmetrical half-divided bodies.

[0038] The protrusion 38 protrudes radially outward from the outer peripheral surface of the second portion 36. Specifically, the protrusion 38 protrudes in a direction intersecting the height direction, which is the demolding direction. The protrusions 38 are arranged in pairs at both circumferential ends of the outer peripheral surface of the second portion 36, positioned below the parting lines 33 at both locations. Each protrusion 38 is arranged close to the parting lines 33 at its respective location. The outer peripheral shape of the cross-section of each protrusion 38 is arc-shaped. The outer peripheral shape of the cross-section of the second portion 36, except for each protrusion 38, is arc-shaped (semi-circular). Figure 4 As shown, the protrusion 38 is formed as a rib extending along the axial direction. Here, the protrusion 38 is continuously formed on the outer peripheral surface of the main body 31 and each of the enlarged diameter portions 32.

[0039] When forming the sheath 30B, similarly to Embodiment 1 described above, the first part 35 is formed by the sheath forming cavity 61 of the first mold 80, and the second part 36 is formed by the sheath forming cavity 61 of the second mold 90. The first part 35 as a whole does not have an undercut shape. Therefore, when the mold is opened, the first part 35 can be easily demolded from the first mold 80. On the other hand, the second part 36 has an undercut shape due to the protrusions 38. Therefore, when the mold is opened, the protrusions 38, which are undercuts, generate demolding resistance, and the second part 36 can remain in the second mold 90. As a result, the wiring component 10, as a molded product, always remains in the second mold 90, and the wiring component 10 can be easily removed from the second mold 90.

[0040] In this embodiment 2, the undercut shape is formed by a protrusion 38 protruding from the outer peripheral surface of the second part 36. Therefore, by adjusting the shape, protrusion size, and angle position of the protrusion 38, the demolding resistance of the second part 36 during demolding can be set to an appropriate value. In particular, since the protrusion 38 is arranged close to the parting line 33, it is possible to avoid the demolding resistance of the second part 36 during demolding becoming too large due to the protrusion 38.

[0041] <Implementation Method 3> use Figure 6 and Figure 7 The wiring component 10 of Embodiment 3 of this disclosure will be described. The wiring component 10 of Embodiment 3 differs from that of Embodiment 1 in that the parting line 33 is positioned and the shapes of the first portion 35 and the second portion 36 are respectively. The fact that the molding portion 30 is a sheath 30C and that the sheath 30C has a main body portion 31 and a pair of expanded diameter portions 32 are the same as those in Embodiment 1.

[0042] In this embodiment 3, the parting line 33 is positioned at the center of the wiring component 10 in the height direction of the sheath 30C (radial direction, demolding direction of the first mold 80 and the second mold 90) when viewed from the side. Specifically, the parting line 33 is positioned at the same height as the center of the wire 20.

[0043] When the sheath 30C is imaginarily divided in the height direction into an upper part 35 and a lower part 36 via an imaginary plane 34 containing parting lines 33 at two points on the outer periphery, the first part 35 and the second part 36 are configured to be asymmetrical shapes.

[0044] like Figure 7As shown, the first portion 35 has non-undercut recesses 41 extending along the height direction, which is the demolding direction, inside the first portion 35. The non-undercut recesses 41 are arranged in pairs on either side of an imaginary axis of symmetry 42 orthogonal to the imaginary plane 34 and passing through the center of the wire 20. The upper end of each non-undercut recess 41 opens onto the outer peripheral surface of the first portion 35. The lower end of each non-undercut recess 41 is closed by the outer peripheral surface of the wire 20. That is, each non-undercut recess 41 has its bottom surface 41A (inside) on the outer peripheral surface of the wire 20. The outer peripheral shape of the cross-section of the first portion 35, except for the openings of each non-undercut recess 41, is arc-shaped (semi-circular). Since the non-undercut recesses 41 are formed along the demolding direction, the first portion 35 does not have an undercut shape. Figure 6 As shown, the non-overlapping recess 41 is formed as a slit-like groove extending along the axial direction. Here, the non-overlapping recess 41 is formed along the entire axial length of the main body portion 31.

[0045] like Figure 7 As shown, the second portion 36 has undercut recesses 43 extending inside the second portion 36 in a direction intersecting the height direction, which is the demolding direction. The undercut recesses 43 are arranged in pairs on the left and right sides separated by an imaginary axis of symmetry 42. The lower end of each undercut recess 43 opens onto the outer peripheral surface of the second portion 36. The upper end of each undercut recess 43 is closed by the outer peripheral surface of the wire 20. That is, each undercut recess 43 has its bottom surface 43A (inside) on the outer peripheral surface of the wire 20. Each undercut recess 43 expands in such a way that the openings become increasingly separated from each other as they move from the bottom surface 43A towards the outer peripheral surface. The outer peripheral shape of the cross-section of the second portion 36, except for the openings of each undercut recess 43, is arc-shaped (semi-circular). Because the undercut recesses 43 are formed in a direction intersecting the demolding direction, the second portion 36 has an undercut shape. Figure 6 As shown, the undercut recess 43 is formed as a slit-like groove extending along the axial direction. Here, each undercut recess 43 is formed along the entire axial length of the main body 31.

[0046] In this embodiment 3, when forming the sheath 30C, in addition to the first mold 80 as the upper mold and the second mold 90 as the lower mold, a pressing mold (not shown) for pressing the wire 20 is also used. Each pressing mold is configured to slide relative to each mold of the first mold 80 and the second mold 90. Each pressing mold has a corresponding shape at a position corresponding to each non-undercut recess 41 and each undercut recess 43.

[0047] With the first mold 80 and the second mold 90 closed and a sheath forming cavity 61 formed inside, the wire 20, which is an insert component, is held by each die. When molten material is filled into the sheath forming cavity 61, the movement of the wire 20 is suppressed by each die. When the first mold 80 is opened relative to the second mold 90, the first part 35 can be easily demolded from the first mold 80 because each die in the first mold 80 is arranged in the demolding direction corresponding to each non-undercut recess 41. On the other hand, since each die in the second mold 90 is arranged in a direction intersecting the demolding direction in a manner corresponding to each undercut recess 43, the second part 36 can be reliably retained in the second mold 90. Then, each die in the second mold 90 is pulled out, and the wiring component 10, which is a molded product, is removed from the second mold 90. Each non-undercut recess 41 and undercut recess 43 is formed along with the pulling out of each die.

[0048] In this embodiment 3, the undercut shape is formed by an undercut recess 43 that extends inside the second part 36 in a direction intersecting the demolding direction and opens on the outer peripheral surface of the second part 36, thus preventing the second part 36 and even the outer peripheral shape of the wiring component 10 from becoming larger.

[0049] In this embodiment 3, the sheath 30C has a non-overlapping recess 41 that extends in the demolding direction inside the first portion 35 and opens on the outer peripheral surface of the first portion 35. The bottom surfaces 41A and 43A of the overlapping recess 43 and the non-overlapping recess 41 are formed by the outer peripheral surface of the wire 20. The overlapping recess 43 and the non-overlapping recess 41 are formed with the removal of the mold for pressing the wire 20. Therefore, it is not necessary to make the overlapping recess 43 and the non-overlapping recess 41 dedicated parts that only form an overlapping shape and a non-overlapping shape, respectively.

[0050] [Other embodiments of this disclosure] The embodiments 1-3 disclosed herein are illustrative and not restrictive in all respects. In the embodiments 1-3 described above, the outer periphery of the cross-section of the wiring component is circular. Conversely, the outer periphery of the cross-section of the wiring component may also be non-circular, including polygons such as quadrilaterals. The wire may also be a flat wire or the like with a non-circular outer periphery of its cross-section. In embodiments 1-3 described above, the molding part is a sheath. In contrast, according to other embodiments, the molding part is not limited to a sheath, and may be, for example, a resin molded body that cannot be elastically deformed. In embodiment 3 described above, the bottom surfaces of both the undercut recess and the non-undercut recess are formed by the outer peripheral surface of the wire. In contrast, according to other embodiments, the bottom surfaces of both the undercut recess and the non-undercut recess may not reach the outer peripheral surface of the wire and may be closed inside the molding section. Alternatively, a structure may be adopted in which only the undercut recess is provided in the molding section, and no non-undercut recess is provided. In the case of embodiment 3 described above, openings for both the undercut recess and the non-undercut recess are formed on the outer peripheral surface of the molding portion. In contrast, according to other embodiments, a mounting member may be installed on the outer peripheral surface of the molding portion, and the openings of both the undercut recess and the non-undercut recess may be closed by the mounting member. For example, a strip serving as the mounting member may be wound around the outer peripheral surface of the molding portion to close the openings of both the undercut recess and the non-undercut recess. Alternatively, the mounting member may be a clip or the like that used to fix the parts to a vehicle. Symbol Explanation
