The groove is a parting groove for improving the appearance of the interior material, for example, by accommodating the end of the skin material adhered to the surface of the interior material.

特許第4107583号公報Japanese Patent No. 4107583

しかしながら、上記の内装材では、第1成形品と第2成形品が境界部分において面接触状態で接合しているに過ぎないため、この接合面では十分な接合強度を得ることができない。したがって、例えば内装材に曲げ応力が加わった場合に、脆弱部である溝部に応力が集中してしまい、第1成形品と第2成形品が接合面で破断するおそれがある。   However, in the above interior material, since the first molded product and the second molded product are merely joined in a surface contact state at the boundary portion, sufficient joining strength cannot be obtained at this joining surface. Therefore, for example, when bending stress is applied to the interior material, the stress concentrates in the groove portion which is the fragile portion, and the first molded product and the second molded product may be broken at the joint surface.

本発明は上記のような事情に基づいて完成されたものであって、溝部における第1成形品と第2成形品の接合強度を向上させ、かつ、外観見栄えを向上させることを目的とする。   This invention is completed based on the above situations, Comprising: It aims at improving the joining strength of the 1st molded product and 2nd molded product in a groove part, and improving the external appearance.

本発明は、第1成形品と、この第1成形品とは異種の材質あるいは同種の材質で色が異なるものからなる第2成形品とを備え、第1成形品と第2成形品との連結部に沿って溝部が形成され、この溝部の側壁を構成する立壁部が第1成形品の周縁に連設され、溝部の奥壁を構成するフランジ部が立壁部に連設され、フランジ部の一部を延設してなる延長部が断続的に形成された内装材の製造方法であって、第1成形品を成形し、第2成形品を成形する成形型のうち一方の型に第1成形品を載置し、同他方の型に設けた押さえ部をフランジ部に押圧することで第2成形品の成形空間の内部をシールするとともに成形空間に延長部を位置させて成形型を型閉じし、延長部が第2成形品から離脱するとした場合における離脱経路上に樹脂を回り込ませて延長部を覆い部で覆うことにより連結部を成形するところに特徴を有する。   The present invention includes a first molded product and a second molded product made of a different material or the same type of material and having a different color, and the first molded product and the second molded product. A groove portion is formed along the connecting portion, a standing wall portion constituting the side wall of the groove portion is continuously provided on the peripheral edge of the first molded product, and a flange portion constituting the rear wall of the groove portion is continuously provided on the standing wall portion. A method of manufacturing an interior material in which an extension part formed by extending a part of the interior material is intermittently formed, wherein a first molded product is molded and a second molded product is molded into one of the molds Place the first molded product and press the pressing part provided on the other mold against the flange part to seal the inside of the molding space of the second molded product and position the extension part in the molding space. When the mold is closed and the extension part is detached from the second molded product, the resin is caused to wrap around the separation path. Characterized in place of forming the connecting portion by covering the extended portion in the cover portion.

このようにすると、延長部の離脱経路上に樹脂を回り込ませているため、溝部における第1成形品と第2成形品の接合強度を向上させることができる。また、第1成形品と第2成形品との接合部を溝部の奥方に位置させることで、内装材の外観見栄えを向上させることができる。このため、意匠性を損なうことなく第1成形品と第2成形品を強固に接合することができる。   If it does in this way, since resin is made to wrap around on the separation path of an extension part, the joint strength of the 1st molded product and the 2nd molded product in a slot can be improved. Moreover, the appearance appearance of the interior material can be improved by positioning the joint portion between the first molded product and the second molded product at the back of the groove portion. For this reason, a 1st molded product and a 2nd molded product can be joined firmly, without impairing design nature.

本発明の実施の態様として、以下のようにしてもよい。
延長部は貫通孔を有しており、この貫通孔の内部に樹脂を充填することにより離脱経路上に樹脂を回り込ませるようにしてもよい。
このようにすると、貫通孔の内部に充填された樹脂により延長部を引っ掛けて固定できるため、第1成形品と第2成形品の接合強度をさらに向上させることができる。
As an embodiment of the present invention, the following may be adopted.
The extension portion has a through hole, and the resin may be wound around the separation path by filling the inside of the through hole with resin.
If it does in this way, since an extension part can be hooked and fixed with resin with which the inside of a penetration hole was filled, the joint strength of the 1st molded product and the 2nd molded product can further be improved.

また、本発明は、第1成形品と、この第1成形品とは異種の材質あるいは同種の材質で色が異なるものからなる第2成形品とを備え、第1成形品と第2成形品との連結部に沿って溝部が形成され、この溝部の側壁を構成する立壁部が第1成形品の周縁に連設され、溝部の奥壁を構成するフランジ部が立壁部に連設され、フランジ部の一部を延設してなる板状の延長部が断続的に形成された内装材であって、連結部は、延長部と、延長部が第2成形品から離脱するとした場合における離脱経路上に樹脂を回り込ませて延長部を覆う覆い部とからなる構成としてもよい。   The present invention also includes a first molded product and a second molded product made of a different material or the same type of material and having a different color, the first molded product and the second molded product. A groove portion is formed along the connecting portion, and a standing wall portion constituting the side wall of the groove portion is continuously provided on the peripheral edge of the first molded product, and a flange portion constituting the back wall of the groove portion is continuously provided on the standing wall portion, It is an interior material in which a plate-like extension part formed by extending a part of the flange part is formed intermittently, and the connecting part is an extension part and the extension part is separated from the second molded product It is good also as a structure which consists of a cover part which makes resin wrap around on a detachment path | route and covers an extension part.

このような構成によると、例えば内装材に曲げ応力が加わるなどして溝部に応力が集中した場合であっても、延長部が覆い部に覆われて保持されているため、第1成形品と第2成形品が溝部で破断することを回避できる。また、第1成形品と第2成形品との接合部を溝部の奥方に位置させることができるため、内装材の外観見栄えを向上させることができる。   According to such a configuration, for example, even when bending stress is applied to the interior material and the stress is concentrated in the groove portion, the extension portion is covered and held by the cover portion, so the first molded product and It can avoid that a 2nd molded product fractures | ruptures in a groove part. Moreover, since the junction part of a 1st molded product and a 2nd molded product can be located in the back of a groove part, the external appearance appearance of an interior material can be improved.

本発明によれば、溝部における第1成形品と第2成形品の接合強度を向上させることができ、かつ、外観見栄えを向上させることができる。   ADVANTAGE OF THE INVENTION According to this invention, the joint strength of the 1st molded product and 2nd molded product in a groove part can be improved, and an external appearance can be improved.

<実施形態1>
本発明の実施形態1を図1ないし図6の図面を参照しながら説明する。本実施形態では、内装材として、車両ドアに取り付けられるドアトリム10を例示している。図1は、本実施形態のドアトリム10の斜視図である。図1に示すように、ドアトリム10は、合成樹脂等によって板状に形成されたドアトリム本体12、アームレスト20などを備えている。アームレスト20は、合成樹脂等によって形成され、ドアトリム本体12の車室内側に張り出す形で配されている。また、ドアトリム10は、オーナメント14、スピーカグリル16、ドアポケット18などを備えている。ドアトリム本体12とオーナメント14との境界には、溝部22が全周に亘って凹設されている。
<Embodiment 1>
Embodiment 1 of the present invention will be described with reference to the drawings of FIGS. In this embodiment, the door trim 10 attached to a vehicle door is illustrated as an interior material. FIG. 1 is a perspective view of a door trim 10 of the present embodiment. As shown in FIG. 1, the door trim 10 includes a door trim main body 12 and an armrest 20 formed in a plate shape with a synthetic resin or the like. The armrest 20 is formed of a synthetic resin or the like, and is arranged so as to project to the vehicle interior side of the door trim body 12. The door trim 10 includes an ornament 14, a speaker grill 16, a door pocket 18, and the like. At the boundary between the door trim main body 12 and the ornament 14, a groove portion 22 is recessed over the entire circumference.

図2は、図1におけるA−A線断面図である。ドアトリム本体12は、ドアトリム基材24を備え、このドアトリム基材24の表面にはシボ模様が形成されている。一方、オーナメント14は、オーナメント基材28を備え、このオーナメント基材28の表面にもシボ模様が形成されている。   FIG. 2 is a cross-sectional view taken along the line AA in FIG. The door trim main body 12 includes a door trim base material 24, and a texture pattern is formed on the surface of the door trim base material 24. On the other hand, the ornament 14 includes an ornament base material 28, and a texture pattern is also formed on the surface of the ornament base material 28.

ドアトリム基材24とオーナメント基材28は、それぞれ異なる材質あるいは同種の材質で色が異なるものからなる樹脂によって構成されている。したがって、ドアトリム基材24とオーナメント基材28を境界部分において面接触状態で接合しても、両基材24,28の接合面では十分な接合強度を確保することができない。この対策として、ドアトリム基材24とオーナメント基材28のつなぎ目に、これらを連結する連結部40が設けられている。   The door trim base material 24 and the ornament base material 28 are made of resins made of different materials or the same kind of materials and having different colors. Therefore, even if the door trim base material 24 and the ornament base material 28 are joined in a surface contact state at the boundary portion, sufficient joining strength cannot be ensured at the joining surfaces of the base materials 24 and 28. As a countermeasure, a connecting portion 40 that connects the door trim base material 24 and the ornament base material 28 is provided.

連結部40は溝部22に隣り合って配置され、溝部22に沿ってオーナメント基材28の周方向に延出されている。また、連結部40は、オーナメント基材28に設けられた平板状の延長部34と、ドアトリム基材24に設けられたリブ状の覆い部38とによって構成されており、延長部34が覆い部38の内部に埋設されることで、延長部34が覆い部38の内部に抜け止め状態に保持されている。これにより、ドアトリム基材24とオーナメント基材28が連結部40において接合されている。   The connecting portion 40 is disposed adjacent to the groove portion 22 and extends in the circumferential direction of the ornament base material 28 along the groove portion 22. The connecting portion 40 includes a flat extension portion 34 provided on the ornament base material 28 and a rib-like cover portion 38 provided on the door trim base material 24, and the extension portion 34 is a cover portion. The extension portion 34 is held in the cover portion 38 so as not to be detached. Thereby, the door trim base material 24 and the ornament base material 28 are joined at the connecting portion 40.

溝部22の側壁は、オーナメント基材28側の側壁と、ドアトリム基材24側の側壁とからなる。オーナメント基材28の周縁には、立壁部30が連設されており、この立壁部30は、溝部22におけるオーナメント基材28側の側壁を構成している。この立壁部30は、オーナメント基材28の平面方向に対して略直角に配置されている。立壁部30の端縁(図示下端縁)には、フランジ部32が連設されている。このフランジ部32は、オーナメント基材28の平面方向に対して略平行に配置されている。また、フランジ部32は、溝部22の底部を構成している。   The side wall of the groove portion 22 is composed of a side wall on the ornament base material 28 side and a side wall on the door trim base material 24 side. A standing wall portion 30 is continuously provided at the periphery of the ornament base material 28, and the standing wall portion 30 constitutes a side wall on the side of the ornament base material 28 in the groove portion 22. The standing wall portion 30 is disposed substantially at right angles to the plane direction of the ornament base material 28. A flange portion 32 is connected to the end edge (lower end edge in the drawing) of the standing wall portion 30. The flange portion 32 is disposed substantially parallel to the planar direction of the ornament base material 28. Further, the flange portion 32 constitutes the bottom portion of the groove portion 22.

図3に示すように、立壁部30およびフランジ部32は、いずれも溝部22の延出方向に沿ってオーナメント基材28の周方向に延出されている。前記した延長部34は、フランジ部32の端縁において、フランジ部32の一部をその平面方向に延設した形態とされている。このため、延長部34は、オーナメント基材28の平面方向に対して略平行に配置されている。また、延長部34には、貫通孔36が形成されている。延長部34の先端側の外形は円弧状をなしており、貫通孔36の孔形状に沿って形成されている。延長部34は、溝部22の延出方向に沿って等間隔で断続的に複数形成されている。   As shown in FIG. 3, both the standing wall portion 30 and the flange portion 32 are extended in the circumferential direction of the ornament base material 28 along the extending direction of the groove portion 22. The above-described extension portion 34 is configured such that a part of the flange portion 32 is extended in the planar direction at the end edge of the flange portion 32. For this reason, the extension part 34 is disposed substantially parallel to the planar direction of the ornament base material 28. Further, a through hole 36 is formed in the extension portion 34. The outer shape on the distal end side of the extension 34 has an arc shape and is formed along the hole shape of the through hole 36. A plurality of extension portions 34 are formed intermittently at equal intervals along the extending direction of the groove portion 22.

延長部34を内部に埋設してなる覆い部38は、ドアトリム基材24の周縁に設けられている。つまり、覆い部38は、溝部22におけるドアトリム基材24側の側壁を構成している。したがって、延長部34と覆い部38からなる連結部40は、溝部22の一部を構成し、溝部22に沿ってオーナメント基材28の周方向に延出されている。   A cover portion 38 formed by embedding the extension portion 34 is provided on the periphery of the door trim base material 24. That is, the cover 38 constitutes a side wall of the groove 22 on the door trim base material 24 side. Accordingly, the connecting portion 40 including the extension portion 34 and the cover portion 38 constitutes a part of the groove portion 22 and extends in the circumferential direction of the ornament base material 28 along the groove portion 22.

延長部34の貫通孔36の内部には、覆い部38を構成する樹脂が充填されている。このため、延長部34が覆い部38から離脱する方向に引っ張られても、貫通孔36の内部に充填された樹脂が貫通孔36の内壁に係止することによって延長部34の離脱が規制される。このようにして、延長部34は、覆い部38によって抜け止め状態に保持されている。   The inside of the through hole 36 of the extension portion 34 is filled with a resin constituting the cover portion 38. For this reason, even if the extension portion 34 is pulled in the direction of detachment from the cover portion 38, the resin filled in the through hole 36 is locked to the inner wall of the through hole 36, so that the detachment of the extension portion 34 is restricted. The In this way, the extension part 34 is held in a state of being prevented from being detached by the cover part 38.

さらに、延長部34と覆い部38による接合部は、溝部22に沿ってオーナメント基材28の周方向に断続的に複数設けられている。したがって、ドアトリム基材24とオーナメント基材28は全周に亘って強固に固定され、ドアトリム基材24とオーナメント基材28との連結部40における接合強度を向上させることができる。これにより、ドアトリム10に曲げ応力が加わり、溝部22に応力が集中した場合であっても、溝部22でドアトリム10が破断することを防ぐことができる。   Further, a plurality of joint portions by the extension portion 34 and the cover portion 38 are provided intermittently in the circumferential direction of the ornament base material 28 along the groove portion 22. Therefore, the door trim base material 24 and the ornament base material 28 are firmly fixed over the entire circumference, and the joining strength at the connecting portion 40 between the door trim base material 24 and the ornament base material 28 can be improved. Thereby, even if it is a case where bending stress is added to the door trim 10 and stress concentrates on the groove part 22, it can prevent that the door trim 10 is fractured | ruptured by the groove part 22. FIG.

次に、ドアトリム基材24とオーナメント基材28を一体に成形する成形型の構成およびその成形方法について図4ないし図6の図面を参照しながら説明する。溝部22を成形する成形型は、図4に示すように、上型50、この上型50の下方に対向して配置された下型52などを備えて構成されている。上型50には、フランジ部32に対して上方から押さえ付ける押さえ部54が設けられており、下型52には、押さえ部54によって下方に押さえ付けられたフランジ部32を下方から受ける受け部56が設けられている。これにより、フランジ部32は、上下方向において押さえ部54と受け部56の間に挟持される。   Next, a configuration of a molding die for integrally molding the door trim base material 24 and the ornament base material 28 and a molding method thereof will be described with reference to the drawings of FIGS. As shown in FIG. 4, the forming die for forming the groove portion 22 includes an upper die 50, a lower die 52 arranged to face the lower side of the upper die 50, and the like. The upper die 50 is provided with a pressing portion 54 that presses against the flange portion 32 from above. The lower die 52 receives a flange portion 32 that is pressed downward by the pressing portion 54 from below. 56 is provided. Thereby, the flange part 32 is clamped between the pressing part 54 and the receiving part 56 in the up-down direction.

オーナメント基材28の表面には、予めシボ加工が施されており、このオーナメント基材28のシボ形成面を上側に向けた状態で下型52に載置される。成形型を型閉じすると、シボが形成されたフランジ部32のうち押さえ部54で押圧された部分では、シボ模様が消失してしまうものの、押さえ部54と非接触の部分では、シボ模様が保持されるようになっている。また、押さえ部54がフランジ部32を押圧することによって、ドアトリム基材24を成形する成形空間Sの内部がシールされている。   The surface of the ornament base material 28 is pre-textured, and is placed on the lower mold 52 with the texture forming surface of the ornament base material 28 facing upward. When the mold is closed, the wrinkle pattern disappears in the portion pressed by the pressing portion 54 of the flange portion 32 where the wrinkles are formed, but the wrinkle pattern is retained in the portion not in contact with the pressing portion 54. It has come to be. Further, when the pressing portion 54 presses the flange portion 32, the inside of the molding space S for molding the door trim base material 24 is sealed.

成形空間Sは、上型50と下型52によって上下方向に囲まれた領域に形成されている。また、成形空間Sの内壁のうち上型50によって構成される壁面は、シボ模様が形成されたシボ成形面とされている。成形型を型閉じした状態では、延長部34が成形空間Sの底面と天井面の双方から離間した中間位置に水平姿勢で保持されるようになっている。成形空間S内に連通して配置されたゲート(図示せず)から樹脂を射出することで、図5に示すように、成形空間S内に樹脂が充填され、この樹脂が冷え固まることでドアトリム基材24が形成されるとともに、ドアトリム基材24の表面にシボ模様が形成される。   The molding space S is formed in a region surrounded by the upper mold 50 and the lower mold 52 in the vertical direction. Moreover, the wall surface comprised by the upper mold | type 50 among the inner walls of the shaping | molding space S is made into the wrinkle shaping | molding surface in which the wrinkle pattern was formed. In a state where the mold is closed, the extension 34 is held in a horizontal position at an intermediate position spaced from both the bottom surface and the ceiling surface of the molding space S. By injecting resin from a gate (not shown) arranged in communication with the molding space S, the resin is filled into the molding space S as shown in FIG. While the base material 24 is formed, a texture pattern is formed on the surface of the door trim base material 24.

次に、上下両型50,52を上下方向に型開きし、図6に示すように、ドアトリム基材24とオーナメント基材28が一体に成形された一体成形品11を脱型する。このようにして形成された一体成形品11は、覆い部38に延長部34が埋設されているため、両基材24,28に曲げ応力が加わるなどして溝部22に応力が集中した場合であっても、両基材24,28が溝部22で破断することはなく、連結部40で両基材24,28を強固に接合することができる。   Next, both the upper and lower molds 50 and 52 are opened in the vertical direction, and as shown in FIG. 6, the integrally molded product 11 in which the door trim base material 24 and the ornament base material 28 are integrally molded is removed. The integrally molded product 11 formed in this way has an extension portion 34 embedded in the cover portion 38, and therefore, when stress is concentrated in the groove portion 22 due to bending stress applied to both base materials 24 and 28. Even if it exists, both the base materials 24 and 28 will not fracture | rupture in the groove part 22, but both the base materials 24 and 28 can be firmly joined by the connection part 40. FIG.

以上のように本実施形態では、ドアトリム基材24とオーナメント基材28の連結部40に沿って溝部22を形成しているものの、連結部40において延長部34が覆い部38に埋設されているから、ドアトリム基材24とオーナメント基材28を強固に接合できる。また、延長部34に貫通孔36を形成し、この貫通孔36に樹脂が埋め込まれた状態で覆い部38を設けているから、ドアトリム基材24とオーナメント基材28をより強固に接合できる。さらに、延長部34と覆い部38との接合部を溝部22の奥方に配置したから、この接合部が溝部22の外部から視認されることはなく、外観見栄えを向上させることができる。   As described above, in the present embodiment, the groove portion 22 is formed along the connecting portion 40 between the door trim base material 24 and the ornament base material 28, but the extension portion 34 is embedded in the cover portion 38 in the connecting portion 40. Therefore, the door trim base 24 and the ornament base 28 can be firmly joined. Further, since the through hole 36 is formed in the extension portion 34 and the cover portion 38 is provided in a state where the resin is embedded in the through hole 36, the door trim base material 24 and the ornament base material 28 can be more firmly joined. Furthermore, since the joint part of the extension part 34 and the cover part 38 is arrange | positioned in the back of the groove part 22, this joint part is not visually recognized from the exterior of the groove part 22, and appearance appearance can be improved.

<実施形態2>
次に、本発明の実施形態2について図7の図面を参照しながら説明する。本実施形態では、オーナメント基材28の表面にシボ加工が施されておらず、その変わりにオーナメント基材28の表面にオーナメント表皮材26が貼着されている。オーナメント表皮材26としては、例えばクッション性を有し、予め表面にシボ加工が施されたものを使用することができる。また、オーナメント表皮材26の端部は、溝部22の内部に収容され、いわゆる木目込み状態としてオーナメント表皮材26の端末を処理し、外観見栄えを向上させている。さらに、オーナメント表皮材26は、オーナメント基材28に対して、例えばホットメルトテープ(図示せず)を介して貼着されている。
<Embodiment 2>
