Description

本発明は、車両内装部材の製造方法に関し、更に詳細には、取付部材が締結される締結部および該取付部材が係止される係止部を、基材の裏側に形成する車両内装部材の製造方法に関するものである。 The present invention relates to a method for manufacturing a vehicle interior member. More specifically, the present invention relates to a vehicle interior member in which a fastening portion to which a mounting member is fastened and a locking portion to which the mounting member is locked are formed on the back side of a base material. It relates to a manufacturing method.

乗用車等の車両における乗員室内には、図１１に示すように、例えばリアサイドトリム１２、ドアトリム１４、ピラーガーニッシュ１６およびリアゲートトリム１８等の種々の車両内装部材１０が、該乗員室内の側から車体Ｂへ組付けられている。これら車両内装部材１０は、車体の金属部分が乗員室内へ露出しないように被覆するため、比較的大型でかつ複雑な凹凸形状に形成される場合が多く、一般的にはインジェクション成形技術により成形された合成樹脂製の基材２０を主体としている。図１２は、前述したリアサイドトリム１２の裏面を概略的に示した背面図であって、該リアサイドトリム１２を含む前述の車両内装部材１０は、裏面の所要位置に複数のクリップ(車体嵌合手段)Ｃを設けてある。従って車両内装部材１０は、これらクリップＣを車体Ｂに設けた各係止孔Ｂ１(図１３および図１４参照)へ対応的に突入して嵌合させることで、該車体Ｂに対して取外し可能に組付けられる。 As shown in FIG. 11, various vehicle interior members 10 such as a rear side trim 12, a door trim 14, a pillar garnish 16, and a rear gate trim 18 are disposed in the passenger compartment of a vehicle such as a passenger car from the passenger compartment side. Has been assembled. Since these vehicle interior members 10 cover the metal parts of the vehicle body so as not to be exposed to the passenger compartment, they are often formed in a relatively large and complex uneven shape, and are generally formed by injection molding technology. The base material 20 made of synthetic resin is mainly used. FIG. 12 is a rear view schematically showing the rear surface of the rear side trim 12 described above. The vehicle interior member 10 including the rear side trim 12 has a plurality of clips (vehicle body fitting means) at required positions on the rear surface. ) C is provided. Therefore, the vehicle interior member 10 can be removed from the vehicle body B by fitting these clips C into the respective locking holes B1 (see FIGS. 13 and 14) provided in the vehicle body B in a corresponding manner. Assembled to.

前述した車両内装部材１０は、基材２０の裏面が複雑な凹凸形状に形成されているため、車体Ｂに組付けた際の基材２０と車体Ｂとの間隔が各部位毎に異なっている。従って基材２０の裏面には、図１３および図１４に示すように、所謂「やぐら形状」をなす所要高さの取付台座部２２または取付台座部材(取付部材)２４が設けられており、これら取付台座部２２の上面および取付台座部材２４の上面にクリップＣが取付けられている。図１３に示した取付台座部２２は、基材２０に一体的に形成されたものであって、基材２０を成形する成形型のスライド機構を利用して成形可能な場合は、このように基材２０に一体的に形成することが多い。 In the vehicle interior member 10 described above, since the back surface of the base material 20 is formed in a complicated uneven shape, the distance between the base material 20 and the car body B when assembled to the car body B is different for each part. . Therefore, as shown in FIG. 13 and FIG. 14, a mounting base portion 22 or a mounting base member (mounting member) 24 having a so-called “tower-shaped” height is provided on the back surface of the base material 20. Clips C are attached to the upper surface of the mounting base portion 22 and the upper surface of the mounting base member 24. The mounting base portion 22 shown in FIG. 13 is formed integrally with the base material 20 and can be formed using a slide mechanism of a forming die for forming the base material 20 as described above. Often formed integrally with the substrate 20.

また、図１４に示した取付台座部材２４は、基材２０とは別体に形成されたものであって、隣接した部位に突部や壁部等があって成形型により取付台座部２２の成形が不可能な場合は、基材２０の付属部材として該基材２０とは別体に該取付台座部材２４を成形して、後工程において該基材２０に組付けるようになっている。この場合には、基材２０の裏面にボス状の突部２８,２８等からなる設置支持部２６を成形し、別体に成形した取付台座部材２４を、タッピングネジＳ等を利用して設置支持部２６に組付けるよう構成される。 Further, the mounting base member 24 shown in FIG. 14 is formed separately from the base material 20, and has projections and wall portions at adjacent portions, and the mounting base member 22 is formed by a molding die. When molding is impossible, the mounting base member 24 is molded separately from the base material 20 as an attachment member of the base material 20 and assembled to the base material 20 in a subsequent process. In this case, the installation support portion 26 composed of the boss-like protrusions 28, 28, etc. is formed on the back surface of the base material 20, and the mounting base member 24 formed separately is installed using the tapping screw S or the like. It is configured to be assembled to the support portion 26.

前述した車両内装部材１０の基材２０は、車体Ｂを被覆し得る形状とするために、図１２および図１４に示すように、車体Ｂに取付けた際に乗員室内へ臨む第１壁部分２０Ａと、第１壁部分２０Ａの端縁部から該第１壁部分２０Ａの後方に向け折曲的に形成された第２壁部分２０Ｂと、第２壁部分２０Ｂの後端縁から内側(第１壁部分２０Ａの後方側)に向け折曲的に形成されて車体Ｂに近接する第３壁部分２０Ｃとを備えたものがある。図１４に示した形状の基材２０は、スライド構造を備えない成形型で成形しようとすると、第２壁部分２０Ｂおよび第３壁部分２０Ｃで形成される部分が所謂アンダーカット形状となり、成形型の型開放および該基材２０の脱型が不可能となってしまう。従って、図１４に示したようなアンダーカット形状を有する基材２０は、例えば図１５に示すようなスライド型８４を備えた成形型Ｍ１を使用して成形するようになっている。 Since the base member 20 of the vehicle interior member 10 described above has a shape that can cover the vehicle body B, the first wall portion 20A that faces the passenger compartment when attached to the vehicle body B as shown in FIGS. A second wall portion 20B that is bent from the end edge of the first wall portion 20A toward the rear of the first wall portion 20A, and an inner side from the rear end edge of the second wall portion 20B (first Some include a third wall portion 20C that is bent toward the rear side of the wall portion 20A and is close to the vehicle body B. When the base material 20 having the shape shown in FIG. 14 is formed with a mold having no slide structure, the portion formed by the second wall portion 20B and the third wall portion 20C has a so-called undercut shape. Therefore, it is impossible to open the mold and to remove the base material 20. Therefore, the base material 20 having an undercut shape as shown in FIG. 14 is formed using, for example, a forming die M1 having a slide die 84 as shown in FIG.

成形型Ｍ１は、成形面８０Ａを設けた第１成形型８０と、成形面８２Ａを設けた第２成形型８２と、第１壁部分２０Ａの一部と第２壁部分２０Ｂおよび第３壁部分２０Ｃを成形するスライド型８４とを有している。第２成形型８２は、図示しない作動装置により該第２成形型８２に対し近接・離間移動が可能な型フレーム８６を有している。この型フレーム８６には、成形型Ｍ１で成形された基材２０を脱型する際に該基材２０を突出す突出しロッド８８と、スライド型８４を第２成形型８２のガイド面８２Ｂに沿って移動させる支持ロッド９０とを有している。支持ロッド９０は、第２成形型８２に対して傾斜状態で貫通しており、一方の端部がフレーム８６に設けたガイドレール８６Ａに対してスライドピン９０Ａを介して連結されている。このような成形型Ｍ１は、図１５に示すように、第２成形型８２から型フレーム８６を離間移動させてスライド型８４を該第２成形型８２へ密着させたもとで、第１成形型８０に対して第２成形型８２を型閉めすることで内部にキャビティＤが画成され、このキャビティＤ内に充填した樹脂を固化させることで、裏面に設置支持部２６を一体的に設けた基材２０を成形し得る。 The molding die M1 includes a first molding die 80 provided with a molding surface 80A, a second molding die 82 provided with a molding surface 82A, a part of the first wall portion 20A, the second wall portion 20B, and the third wall portion. And a slide mold 84 for forming 20C. The second mold 82 has a mold frame 86 that can be moved toward and away from the second mold 82 by an operating device (not shown). The mold frame 86 includes a projecting rod 88 that projects the base material 20 when the base material 20 molded by the mold M1 is removed, and a slide mold 84 along the guide surface 82B of the second mold 82. And a support rod 90 to be moved. The support rod 90 passes through the second mold 82 in an inclined state, and one end thereof is connected to a guide rail 86A provided on the frame 86 via a slide pin 90A. As shown in FIG. 15, such a mold M1 is formed by moving the mold frame 86 away from the second mold 82 and bringing the slide mold 84 into close contact with the second mold 82. On the other hand, the cavity D is defined by closing the second molding die 82, and the resin filled in the cavity D is solidified, so that the installation support portion 26 is integrally provided on the back surface. The material 20 can be molded.

そして、基材２０の成形完了後には、図１６に示すように、先ず第１成形型８０から第２成形型８２を離間移動させて成形型Ｍ１を型開きする。次いで、図１７に示すように、型フレーム８６を第２成形型８２に向けて近接移動させることで、突出しロッド８８が成形面８２Ａから突出すると共に、ガイドレール８６Ａに沿って移動しながら型内に向け突出する支持ロッド９０によりスライド型８４がガイド面８２Ｂに沿って斜め下方へ移動し、成形された基材２０が第２成形型８２の成形面８２Ａから離間されるようになる。すなわちスライド型８４は、図１７から理解できるように、ガイド面８２Ｂに沿って斜めに移動することで、基材２０の第２壁部分２０Ｂおよび第３壁部分２０Ｃから相対的に離間するため、アンダーカット形状を有する該基材２０を第２成形型８２から脱型し得る。なお、取付部材等を組付けるための設置支持部を裏側に設けた基材を成形する車両内装部材の製造方法に関しては、例えば引用文献１等に開示されている。
特開平６−１８２８３０号公報 Then, after the molding of the substrate 20 is completed, as shown in FIG. 16, first, the second mold 82 is moved away from the first mold 80 to open the mold M1. Next, as shown in FIG. 17, by moving the mold frame 86 close to the second mold 82, the protruding rod 88 protrudes from the molding surface 82A and moves along the guide rail 86A while moving inside the mold. The slide mold 84 is moved obliquely downward along the guide surface 82B by the support rod 90 protruding toward the center, so that the molded base material 20 is separated from the molding surface 82A of the second molding die 82. That is, as can be understood from FIG. 17, the slide mold 84 moves obliquely along the guide surface 82 B, so that the slide mold 84 is relatively separated from the second wall portion 20 B and the third wall portion 20 C. The base material 20 having an undercut shape can be removed from the second mold 82. In addition, regarding the manufacturing method of the vehicle interior member which shape | molds the base material which provided the installation support part for assembling an attachment member etc. in the back side, it is disclosed by the cited reference 1, etc., for example.

しかしながら、図１５〜図１７に示した成形型Ｍ１により基材２０を成形する従来の車両内装部材の製造方法では、各図から理解できるように、第２成形型８２の成形面８２Ａに設けた成形凹部９２,９２により、設置支持部２６の各突部２８,２８を成形するようになっていた。しかも、基材２０の第１壁部分２０Ａと型フレーム８６に設けたガイドレール８６Ａとが平行の関係となっているため、第２成形型８２のガイド面８２Ｂに沿って移動するスライド型８４は、第１壁部分２０Ａの裏面に接触した状態で第２壁部分２０Ｂおよび第３壁部分２０Ｃから相対的に離間するようになる。従って、成形型Ｍ１を使用した従来の製造方法では、第２壁部分２０Ｂに近い位置の突部２８(図１４および図１７では図示左側の突部２８)を、スライド型８４が第１壁部分２０Ａの裏面に沿って移動する際に干渉しない位置に形成せざるを得ないことから、突部２８,２８からなる設置支持部２６が第２壁部分２０Ｂからかなり離間した位置に設けられ、この設置支持部２６に装着した取付台座部材２４は、図１４に示すように、取付台座部材２４を第２壁部分２０Ｂの側に傾斜した形状にしても、クリップＣと第２壁部分２０Ｂとの間隔Ｌが大きくなっていた。この間隔Ｌが大きくなると、クリップＣを利用して基材２０を車体Ｂに組付けた場合に、該基材２０の突部２８より第２壁部分２０Ｂの側に位置する第１壁部分２０Ａや、該第２壁部分２０Ｂおよび第３壁部分２０Ｃの熱履歴等に伴う変形を防止できない問題が発生する。 However, in the conventional method for manufacturing a vehicle interior member in which the base material 20 is molded by the molding die M1 shown in FIGS. 15 to 17, as can be understood from each drawing, the molding surface 82A of the second molding die 82 is provided. The projections 28 and 28 of the installation support portion 26 are molded by the molding recesses 92 and 92. Moreover, since the first wall portion 20A of the base member 20 and the guide rail 86A provided on the mold frame 86 are in a parallel relationship, the slide mold 84 that moves along the guide surface 82B of the second molding die 82 is The second wall portion 20B and the third wall portion 20C are relatively separated from each other while being in contact with the back surface of the first wall portion 20A. Therefore, in the conventional manufacturing method using the mold M1, the protrusion 28 (the protrusion 28 on the left side in FIG. 14 and FIG. 17) is located near the second wall portion 20B, and the slide mold 84 is the first wall portion. Since it must be formed at a position that does not interfere when moving along the back surface of 20A, the installation support portion 26 including the projections 28 and 28 is provided at a position that is considerably separated from the second wall portion 20B. As shown in FIG. 14, the mounting pedestal member 24 mounted on the installation support portion 26 is formed such that the mounting pedestal member 24 is inclined toward the second wall portion 20B, and the clip C and the second wall portion 20B. The interval L was large. When the distance L is increased, when the base material 20 is assembled to the vehicle body B using the clip C, the first wall portion 20A located on the second wall portion 20B side from the protrusion 28 of the base material 20. In addition, there arises a problem that deformation due to the heat history of the second wall portion 20B and the third wall portion 20C cannot be prevented.

そこで本発明では、基材を成形する成形型のスライド型により、取付部材を装着するための締結部および係止部を、該基材の裏側に成形するようにした車両内装部材の製造方法を提供することを目的とする。 Therefore, in the present invention, there is provided a method for manufacturing a vehicle interior member in which a fastening portion and a locking portion for mounting an attachment member are formed on the back side of a base material by a slide die of a forming die for forming the base material.

That is, the mounting boss 42 is formed in a direction gradually separating from the first wall portion 20 A as it goes from the base end portion to the tip end portion, and is directed to the back side opening 21 of the base material 20. The mounting boss 42 is integrally formed with cross-shaped ribs 48 and 50 that protrude in the radial direction and extend in the axial direction.

スリット４４は、基材２０の第１壁部分２０Ａの裏側に立設されたリブ５２に所要長に形成されて、該リブ５２の右側端縁部に開口した切り欠きであり、取付台座部材６０の鉤状板部６６が該開口から嵌入して係止される。このスリット４４は、図２に示すように、第１壁部分２０Ａの裏面に対して所要の角度で傾斜した状態、すなわち図左側の奥側から図右側の開口側に向かうに従って第１壁部分２０Ａから徐々に離間する向きに延在するように形成されており、基材２０の裏側開口部２１を指向している。なお、スリット４４が形成されたリブ５２は、図２に示すように、該スリット４４から第１壁部分２０Ａの側に位置する第１当接部５２Ａと、該スリット４４から車体Ｂの側に位置する第２当接部５２Ｂとからなる。 The slit 44 is a notch that is formed in a required length in the rib 52 that is erected on the back side of the first wall portion 20 A of the base material 20, and that is open at the right edge of the rib 52. The hook-shaped plate portion 66 is fitted and locked from the opening. As shown in FIG. 2, the slit 44 is inclined at a required angle with respect to the back surface of the first wall portion 20A, that is, from the back side on the left side of the drawing toward the opening side on the right side of the drawing, the first wall portion 20A. Are formed so as to extend gradually away from each other, and are directed to the back side opening 21 of the base material 20. As shown in FIG. 2, the rib 52 in which the slit 44 is formed has a first contact portion 52A located on the first wall portion 20A side from the slit 44, and a vehicle body B side from the slit 44. It consists of the 2nd contact part 52B located.

従って、設置支持部４０を構成する取付ボス４２およびスリット４４は、何れも第１壁部分２０Ａに対して傾斜して同一方向を指向するように設けられている。すなわち、取付ボス４２およびスリット４４は、図６に示すと共に後述するように、スライド型１０４の成形凹部１２０により成形されるため、成形された基材２０を第２成形型１０２から脱型するに際して、第１壁部分２０Ａおよび第２壁部分２０Ｂの両方から相対的に離間するスライド型１０４の移動方向と同一方向に指向するように形成されている。 Therefore, both the mounting boss 42 and the slit 44 constituting the installation support portion 40 are provided so as to be inclined with respect to the first wall portion 20A and directed in the same direction. That is, the mounting boss 42 and the slit 44 are formed by the molding concave portion 120 of the slide die 104 as shown in FIG. 6 and will be described later. Therefore, when the molded base material 20 is removed from the second molding die 102. The slide mold 104 is relatively oriented away from both the first wall portion 20A and the second wall portion 20B and is directed in the same direction as the moving direction.

なお、実施例の設置支持部４０は、取付ボス４２を補強する前述のリブ５０とスリット４４を設けたリブ５２とは、直線上に整列するように形成されているので、一体的に連設された単一のリブとして構成されている。また、実施例の設置支持部４０は、図３に示すように、リブ５０,５２により連設された取付ボス４２およびスリット４４が、基材２０の上下方向へ所要間隔をおいて２組ずつ設けられている。 In addition, the installation support portion 40 of the embodiment is formed so that the above-described rib 50 that reinforces the mounting boss 42 and the rib 52 provided with the slit 44 are aligned in a straight line. Configured as a single rib. In addition, as shown in FIG. 3, the installation support portion 40 of the embodiment includes two sets of mounting bosses 42 and slits 44 that are continuously provided by ribs 50 and 52 at a predetermined interval in the vertical direction of the base material 20. Is provided.

また、両取付ボス４２,４２の間には、該取付ボス４２と同一方向を指向する位置決めボス５４が、第２壁部分２０Ｂの裏側に立設されている。この位置決めボス５４は、設置支持部４０へ取付台座部材６０を組付けるに際して、該取付台座部材６０に設けた後述の位置決め孔７２に整合して突入し得るようになっており、設置支持部４０に対する取付台座部材６０の位置決めを図るために機能する。更に、スリット４４,４４を形成した両リブ５２,５２の間には、該スリット４４の延在方向と同一方向に沿った支持面５６Ａを有した支持リブ５６,５６が、第１壁部分２０Ａの裏側に突設されている。これら支持リブ５６,５６は、設置支持部４０へ取付台座部材６０を組付けるに際して、該取付台座部材６０の部材本体６２(後述)の底面に接触して案内すると共に、該設置支持部４０に組付けた該取付台座部材６０の部材本体６２を下方から支持するようになっている。 In addition, a positioning boss 54 is provided between the mounting bosses 42 and 42 so as to stand in the same direction as the mounting boss 42 on the back side of the second wall portion 20B. When the mounting base member 60 is assembled to the installation support part 40, the positioning boss 54 can be inserted in alignment with a positioning hole 72 described later provided in the mounting base member 60. It functions to position the mounting base member 60 with respect to. Further, between the ribs 52 and 52 in which the slits 44 and 44 are formed, support ribs 56 and 56 having a support surface 56A along the same direction as the extending direction of the slit 44 are provided in the first wall portion 20A. It protrudes on the back side. When the mounting base member 60 is assembled to the installation support portion 40, these support ribs 56, 56 guide and contact the bottom surface of a member main body 62 (described later) of the mounting base member 60, and The member main body 62 of the assembled mounting base member 60 is supported from below.

取付台座部材６０は、図２および図３に示すように、前述した設置支持部４０の取付ボス４２およびスリット４４が、第１壁部分２０Ａの裏側に対して傾斜した同一方向を指向して、基材２０の裏側開口部２１を指向するように設けられているので、該裏側開口部２１から設置支持部４０に向けて斜め方向から装着し得るようになっている。この取付台座部材６０は、基材２０の後方側を指向するようになる頂部の頂面にクリップＣを着脱可能に装着し得るブロック状の部材本体６２と、第２壁部分２０Ｂに対向する当接板部６４と、部材本体６２を基材２０に装着する方向と交差する幅方向の両側部分から夫々外方へ延出する鉤状板部６６,６６とを有した合成樹脂製の一体成形部材である。部材本体６２の頂面には、クリップＣを装着するための切り欠き状の設置開口部６８が形成されており、この設置開口部６８にクリップＣの軸部が嵌合するようになっている。 As shown in FIGS. 2 and 3, the mounting base member 60 is directed in the same direction in which the mounting boss 42 and the slit 44 of the installation support portion 40 described above are inclined with respect to the back side of the first wall portion 20A. Since it is provided so as to face the back side opening 21 of the base material 20, it can be mounted from the back side opening 21 toward the installation support part 40 from an oblique direction. The mounting base member 60 has a block-shaped member main body 62 on which the clip C can be detachably attached to the top surface of the top portion that is directed to the rear side of the base member 20 and a second wall portion 20B. Integrated molding made of synthetic resin having a contact plate portion 64 and flange-like plate portions 66 and 66 extending outward from both side portions in the width direction intersecting the direction in which the member main body 62 is mounted on the base material 20. It is a member. A notch-shaped installation opening 68 for mounting the clip C is formed on the top surface of the member main body 62, and the shaft portion of the clip C is fitted into the installation opening 68. .

当接板部６４は、図３に示すように、横長のプレート状を呈し、設置支持部４０の各取付ボス４２,４２の先端部へ当接するようになっている。そして、設置支持部４０に対する装着方向と交差する幅方向へ延出した当接板部６４の両側部分には、各取付ボス４２,４２の有底穴４６,４６に夫々対応してタッピングネジＳの挿通を許容する挿通孔７０,７０が穿設されている。また、当接板部６４の幅方向の中央には、基材２０の第２壁部分２０Ｂに設けた前述の位置決めボス５４の挿通を許容する位置決め孔７２が穿設されている。従って、設置支持部４０に対して取付台座部材６０を装着するに際し、位置決め孔７２を位置決めボス５４に整合させることで、各挿通孔７０,７０を各取付ボス４２,４２の有底孔４６,４６に整合させ得るようになっている。 As shown in FIG. 3, the abutment plate portion 64 has a horizontally long plate shape and abuts against the tip end portions of the mounting bosses 42, 42 of the installation support portion 40. Then, tapping screws S corresponding to the bottomed holes 46 and 46 of the mounting bosses 42 and 42 are respectively provided on both side portions of the contact plate portion 64 extending in the width direction intersecting the mounting direction with respect to the installation support portion 40. Insertion holes 70, 70 that allow the insertion of are inserted. In addition, a positioning hole 72 that allows insertion of the positioning boss 54 provided in the second wall portion 20B of the base material 20 is formed in the center in the width direction of the contact plate portion 64. Accordingly, when the mounting base member 60 is mounted on the installation support portion 40, the insertion holes 70, 70 are aligned with the positioning bosses 54 so that the insertion holes 70, 70 are formed in the bottomed holes 46, 42 of the mounting bosses 42, 42, respectively. 46 can be matched.

鉤状板部６６,６６は、図３に示すように、設置支持部４０に対する取付台座部材６０の組付姿勢を基準とした部材本体６２の底部端から側外方へ延出すると共に、各鉤状板部６６の先端部分は所要量だけ組付け方向の前方へ延出して、全体的には鉤状を呈している。これら鉤状板部６６,６６は、前述したスリット４４,４４へ夫々対応的に嵌合し得る厚さに設定されている。また、鉤状板部６６,６６が対応のスリット４４,４４に係合した状態においては、両鉤状板部６６,６６の先端部分は各リブ５２,５２の外側へ延出するようになるため、設置支持部４０に対する取付台座部材６０の幅方向の動きを規制し得るようになっている。 As shown in FIG. 3, the bowl-shaped plate portions 66, 66 extend laterally outward from the bottom end of the member main body 62 with reference to the assembly posture of the mounting base member 60 with respect to the installation support portion 40. The tip portion of the bowl-shaped plate portion 66 extends forward in the assembling direction by a required amount, and has a bowl-like shape as a whole. The flange-shaped plate portions 66 and 66 are set to thicknesses that can be fitted into the slits 44 and 44 described above. Further, in a state where the hook-shaped plate portions 66, 66 are engaged with the corresponding slits 44, 44, the tip portions of both the hook-shaped plate portions 66, 66 extend to the outside of the ribs 52, 52. Therefore, the movement in the width direction of the mounting base member 60 with respect to the installation support portion 40 can be restricted.

前述のように構成された取付台座部材６０は、図２および図３に示すように、当接板部６４を設置支持部４０に対向させた向きに把持し、取付ボス４２,４２およびスリット４４,４４の延在方向から設置支持部４０へ装着する。先ず、両鉤状板部６６,６６を対応のスリット４４,４４の開口部に整合させると共に、位置決め孔７２を位置決めボス５４に整合させる。鉤状板部６６,６６および位置決め孔７２がスリット４４,４４および位置決めボス５４へ各々整合したら、取付台座部材６０を第２壁部分２０Ｂ側へ更に移動させると、両鉤状板部６６,６６がスリット４４,４４へ嵌合し、位置決め孔７２が位置決めボス５４に嵌合すると共に、当接板部６４が各取付ボス４２,４２の先端に当接する。当接板部６４が各取付ボス４２,４２の先端部に当接すると、これら取付ボス４２,４２の有底穴４６,４６と当接板部６４の挿通孔７０,７０とが夫々整合するので、挿通孔７０,７０を介して有底穴４６,４６へタッピングネジＳ,Ｓをネジ込むことで、部材本体６２が支持リブ５６,５６の支持面５６Ａに接触するようになり、設置支持部４０に対して取付台座部材６０が強固に固定される。 As shown in FIGS. 2 and 3, the mounting base member 60 configured as described above holds the contact plate portion 64 in a direction facing the installation support portion 40, and mounts the mounting bosses 42 and 42 and the slit 44. , 44 is attached to the installation support portion 40 from the extending direction. First, the two hook-shaped plate portions 66 and 66 are aligned with the openings of the corresponding slits 44 and 44, and the positioning hole 72 is aligned with the positioning boss 54. When the hook-shaped plate portions 66 and 66 and the positioning hole 72 are aligned with the slits 44 and 44 and the positioning boss 54, respectively, when the mounting base member 60 is further moved to the second wall portion 20B side, both the hook-shaped plate portions 66 and 66 are moved. Are fitted into the slits 44, 44, the positioning holes 72 are fitted into the positioning bosses 54, and the abutting plate portions 64 are brought into contact with the tips of the mounting bosses 42, 42. When the abutting plate portion 64 comes into contact with the tip ends of the mounting bosses 42, 42, the bottomed holes 46, 46 of the mounting bosses 42, 42 and the insertion holes 70, 70 of the abutting plate portion 64 are aligned. Therefore, by screwing the tapping screws S, S into the bottomed holes 46, 46 through the insertion holes 70, 70, the member main body 62 comes into contact with the support surfaces 56A of the support ribs 56, 56, and the installation support The mounting base member 60 is firmly fixed to the portion 40.

そして、当接板部６４と取付ボス４２との締結方向と、鉤状板部６６とスリット４４との係脱方向とは、図１に示すように、何れも、車体Ｂに対するクリップＣの組付け方向と所要角度で交差する方向となっており、車体Ｂに対する該クリップＣの組付け方向と同一方向とはなっていない。すなわち、設置支持部４０に対する取付台座部材６０の脱離方向(取付ボス４２およびスリット４４に対するタッピングネジＳおよび鉤状板部６６の脱離方向)Ｐは、該取付台座部材６０の組付け方向と反対向きとなるから、車体Ｂに対するクリップＣの組付け方向Ｑと異なっている(交差している)。更に、鉤状板部６６とスリット４４との係止位置は、図１に示すように、取付ボス４２の先端より、該取付ボス４２が指向する方向に離間した位置にある。従って、取付台座部材６０を装着した基材２０を車体Ｂに組付ける際には、第１壁部分２０Ａを車体Ｂに向けて押すと、前述した取付ボス４２とリブ５２の第１当接部５２Ａを介して取付台座部材６０が支えられるようになり、車体Ｂの係止孔Ｂ１に対するクリップＣの嵌合が効率的になされる構造となっている。一方、取付台座部材６０を装着した基材２０を車体Ｂから取外す際には、該基材２０を引っ張ると、前述した取付ボス４２とリブ５２の第２当接部５２Ｂが取付台座部材６０を後方側から支えるようになり、係止孔Ｂ１からのクリップＣの脱抜が効率的になされる構造となっている。すなわち、クリップＣによって車体Ｂに組付けられている車両内装部材１０を該車体Ｂから取外す場合には、該クリップＣが係止孔Ｂ１から脱抜する際に、取付ボス４２からタッピングネジＳが脱抜するような応力を受けても、当接板部６４と該取付ボス４２との締結が解除することを好適に防止できる。 The fastening direction between the abutting plate portion 64 and the mounting boss 42 and the engagement / disengagement direction between the bowl-shaped plate portion 66 and the slit 44 are both set of the clip C with respect to the vehicle body B as shown in FIG. It is a direction that intersects the attaching direction at a required angle, and is not the same direction as the attaching direction of the clip C to the vehicle body B. That is, the detaching direction of the mounting pedestal member 60 with respect to the installation support part 40 (the detaching direction of the tapping screw S and the bowl-shaped plate part 66 with respect to the mounting boss 42 and the slit 44) P is the assembling direction of the mounting pedestal member 60. Since it is in the opposite direction, it differs from the assembly direction Q of the clip C with respect to the vehicle body B (intersects). Further, as shown in FIG. 1, the locking position between the hook-shaped plate portion 66 and the slit 44 is at a position away from the tip of the mounting boss 42 in the direction in which the mounting boss 42 is directed. Therefore, when the base member 20 with the mounting base member 60 mounted thereon is assembled to the vehicle body B, when the first wall portion 20A is pushed toward the vehicle body B, the first contact portion between the mounting boss 42 and the rib 52 described above. The mounting base member 60 is supported via 52A, and the clip C is efficiently fitted into the locking hole B1 of the vehicle body B. On the other hand, when the base material 20 to which the mounting base member 60 is mounted is removed from the vehicle body B, when the base material 20 is pulled, the above-described mounting boss 42 and the second contact portion 52B of the rib 52 cause the mounting base member 60 to be removed. The structure is such that the clip C is supported from the rear side, and the clip C can be efficiently removed from the locking hole B1. That is, when the vehicle interior member 10 assembled to the vehicle body B by the clip C is removed from the vehicle body B, the tapping screw S is removed from the mounting boss 42 when the clip C is removed from the locking hole B1. Even if it receives stress such as removal, it is possible to suitably prevent the fastening of the contact plate portion 64 and the mounting boss 42 from being released.

次に、実施例に係る車両内装部材１０の製造方法に使用される成形型Ｍ２を、図４を参照して説明する。この成形型Ｍ２は、基材２０の表面意匠形状を再現可能な成形面１００Ａを有する第１成形型１００と、第１成形型１００に対して型閉め可能で、基材２０の裏面形状を再現可能な第２成形型１０２と、第２成形型１０２に対して斜めに往復スライド移動するスライド型１０４とを有している。 Next, a mold M2 used in the method for manufacturing the vehicle interior member 10 according to the embodiment will be described with reference to FIG. The molding die M2 can be closed with respect to the first molding die 100 having the molding surface 100A capable of reproducing the surface design shape of the base material 20 and the first molding die 100, and reproduces the back surface shape of the base material 20. It has a possible second mold 102 and a slide mold 104 that reciprocally slides relative to the second mold 102.

第２成形型１０２は、図示しない作動装置により該第２成形型１０２に対し近接・離間移動が可能な型フレーム１０６を有している。この型フレーム１０６には、成形型Ｍ２で成形された基材２０を脱型する際に該基材２０を突出す突出しロッド１０８と、スライド型１０４を第２成形型１０２のガイド面１０２Ｂに沿って移動させる支持ロッド１１０とを有している。突出しロッド１０８は、第２成形型１０２の成形面１０２Ａに対して垂直方向へ貫通するように配設され、一方の端部が型フレーム１０６に端部固定され、他方の端部が成形面１０２Ａに臨んでいる。また支持ロッド１１０は、第２成形型１０２に対して傾斜状態で貫通するように配設され、一方の端部がフレーム１０６に設けたガイドレール１０６Ａに対してスライドピン１１０Ａを介して連結され、他方の端部がスライド型１０４に固定されている。そして、型フレーム１０６に配設したガイドレール１０６Ａは、基材２０の第１壁部分２０Ａの裏側に対応する第２成形型１０２の成形面１０２Ａとは平行となっておらず、該成形面１０２Ａと所要の角度で斜めに延在している。すなわちガイドレール１０６Ａは、図４に示すように、型フレーム１０６の端部側から中央側に向かうに従って第２成形型１０２(成形面１０２Ａ)から離間するよう斜めに延在している。 The second mold 102 has a mold frame 106 that can be moved toward and away from the second mold 102 by an operating device (not shown). The mold frame 106 includes a projecting rod 108 that projects the base material 20 when the base material 20 molded by the mold M2 is removed, and a slide mold 104 along the guide surface 102B of the second mold 102. And a support rod 110 to be moved. The protruding rod 108 is disposed so as to penetrate in a direction perpendicular to the molding surface 102A of the second mold 102, one end is fixed to the mold frame 106, and the other end is the molding surface 102A. It faces. The support rod 110 is disposed so as to penetrate the second molding die 102 in an inclined state, and one end thereof is connected to a guide rail 106A provided on the frame 106 via a slide pin 110A. The other end is fixed to the slide mold 104. The guide rail 106A disposed on the mold frame 106 is not parallel to the molding surface 102A of the second molding die 102 corresponding to the back side of the first wall portion 20A of the base member 20, and the molding surface 102A. And extends diagonally at the required angle. That is, as shown in FIG. 4, the guide rail 106 A extends obliquely so as to be separated from the second molding die 102 (molding surface 102 A) from the end side to the center side of the die frame 106.

一方、スライド型１０４には、第１成形型１００に対面する型面に開放し、設置支持部４０を成形するための成形凹部１２０が凹設されている。この成形凹部１２０は、前述した取付ボス４２を成形するための第１成形部１２２と、前述したスリット４４を含むリブ５２を成形するための第２成形部１２４とを有しており、成形型Ｍ２を型閉めした際には(図４)、内部に画成されるキャビティＤの一部を構成するようになる。なお、第１成形部１２２および第２成形部１２４は連通しており、該第１成形部１２２は、第２壁部分２０Ｂに対応するスライド型１０４の壁面(図４では垂直部分)に開口しており、第２成形部１２４は、第１壁部分２０Ａに対応する該スライド型１０４の壁面(図４では水平部分)に開口している。 On the other hand, the slide mold 104 is provided with a molding recess 120 for opening the mold surface facing the first molding mold 100 and molding the installation support portion 40. The molding recess 120 includes a first molding portion 122 for molding the mounting boss 42 described above and a second molding portion 124 for molding the rib 52 including the slit 44 described above. When the mold M2 is closed (FIG. 4), a part of the cavity D defined inside is formed. The first molding part 122 and the second molding part 124 communicate with each other, and the first molding part 122 opens on the wall surface (vertical part in FIG. 4) of the slide mold 104 corresponding to the second wall part 20B. The second molding portion 124 opens in the wall surface (horizontal portion in FIG. 4) of the slide mold 104 corresponding to the first wall portion 20A.

前述のように構成された成形型Ｍ２は、図４に示すように、型フレーム１０６を第２成形型１０２から最大に離間するように移動させることで、第１成形型１００に対する第２成形型１０２の型閉めおよび型開きが可能となる。そして、第１成形型１００と第２成形型１０２とを型閉めすることで、前述した成形凹部１２０に連通するキャビティＤが内部に画成され、このキャビティＤ内で充填した樹脂を固化させることで、成形された基材２０における第２壁部分２０Ｂの裏側に、設置支持部４０における取付ボス４２を成形すると共に、該取付ボス４２より第１壁部分２０Ａに近い位置(第１壁部分２０Ａの裏側)に、該設置支持部４０におけるスリット４４を成形することが可能となっている。なお、型フレーム１０６を最大に離間させた状態では、支持ロッド１１０のスライドピン１１０Ａが、ガイドレール１０６Ａの左端に位置する。 As shown in FIG. 4, the mold M2 configured as described above moves the mold frame 106 away from the second mold 102 to the maximum, thereby allowing the second mold relative to the first mold 100 to move. 102 can be closed and opened. Then, by closing the first molding die 100 and the second molding die 102, the cavity D communicating with the molding recess 120 described above is defined inside, and the resin filled in the cavity D is solidified. Thus, the mounting boss 42 of the installation support portion 40 is formed on the back side of the second wall portion 20B of the molded base material 20, and the position closer to the first wall portion 20A than the mounting boss 42 (the first wall portion 20A). The slit 44 in the installation support portion 40 can be formed on the back side of the device. In the state where the mold frame 106 is spaced apart to the maximum, the slide pin 110A of the support rod 110 is positioned at the left end of the guide rail 106A.

そして成形型Ｍ２は、第１成形型１００に対して第２成形型１０２を開放したもとで(図５)、型フレーム１０６を第２成形型１０２へ近接するように移動させると、図６に示すように、突出しロッド１０８が第２成形型１０２の成形面１０２Ａから突出すると共に、スライド型１０４がガイド面１０２Ｂに沿って移動して第２成形型１０２から突出するようになっている。しかも前述したように、ガイドレール１０６Ａが、型フレーム１０６の端部側から中央部に向けて傾斜した状態に形成されているので、型フレーム１０６が第２成形型１０２に向けて移動する際は、スライドピン１１０Ａがガイドレール１０６Ａに沿って右端方向へ移動すると、スライド型１０４は型フレーム１０６に対して相対的に近接移動する。 When the mold M2 is moved so as to be close to the second mold 102 with the second mold 102 opened relative to the first mold 100 (FIG. 5), FIG. As shown, the protruding rod 108 protrudes from the forming surface 102A of the second forming die 102, and the slide die 104 moves along the guide surface 102B to protrude from the second forming die 102. In addition, as described above, the guide rail 106A is formed so as to be inclined from the end side of the mold frame 106 toward the center portion. Therefore, when the mold frame 106 moves toward the second mold 102, When the slide pin 110A moves toward the right end along the guide rail 106A, the slide mold 104 moves relatively close to the mold frame 106.

すなわち、実施例の成形型Ｍ２は、型フレーム１０６を第２成形型１０２に向けて移動させる際に、突出しロッド１０８およびスライド型１０４の両方が該第２成形型１０２から延出するようになるものの、突出しロッド１０８の移動速度よりもスライド型１０４の移動速度が相対的に小さくなるよう構成されている。従ってスライド型１０４は、図６および図７に示すように、成形された基材２０を突出しロッド１０８を利用して第２成形型１０２から脱型するに際し、第２成形型１０２から離間する該基材２０の第１壁部分２０Ａおよび第２壁部分２０Ｂの両方から相対的に離間する方向へ移動するようになる。そして、図７に示すように、型フレーム１０６が第２成形型１０２へ最接近すると、スライド型１０４は第３壁部分２０Ｃの後端縁部より内側へ移動すると共に、基材２０に成形された設置支持部４０が成形凹部１２０から抜け出るようになり、該基材２０が第２成形型１０２から脱型することを許容する。 That is, when the mold M2 of the embodiment moves the mold frame 106 toward the second mold 102, both the protruding rod 108 and the slide mold 104 extend from the second mold 102. However, the moving speed of the slide mold 104 is relatively smaller than the moving speed of the protruding rod 108. Accordingly, as shown in FIGS. 6 and 7, the slide mold 104 protrudes from the second molding die 102 when the molded base material 20 protrudes and is removed from the second molding die 102 using the rod 108. The base 20 moves in a direction relatively away from both the first wall portion 20A and the second wall portion 20B. As shown in FIG. 7, when the mold frame 106 is closest to the second mold 102, the slide mold 104 moves inward from the rear edge of the third wall portion 20C and is molded into the base material 20. Further, the installation support part 40 comes out of the molding recess 120, and the base material 20 is allowed to be removed from the second molding die 102.

前述のように構成された成形型Ｍ２を使用した実施例に係る車両内装部材１０の製造方法は、先ず図４に示すように、第２成形型１０２に対して型フレーム１０６を最大に離間させ、突出しロッド１０８の先端を第２成形型１０２の成形面１０２Ａと面一とすると共に、スライド型１０４を第２成形型１０２に密着させたもとで、第１成形型１００に対して第２成形型１０２を型閉めする。そして、成形型Ｍ２内に画成された成形凹部１２０を含むキャビティＤ内へ、溶融した所要量の合成樹脂材料を射出して固化させることで、第１壁部分２０Ａと、第１壁部分２０Ａの端縁部から該第１壁部分２０Ａの後方に向け折曲的に形成された第２壁部分２０Ｂと、第２壁部分２０Ｂの後端縁部から内側に向け折曲的に形成された第３壁部分２０Ｃとを備えた基材２０を成形する。 In the manufacturing method of the vehicle interior member 10 according to the embodiment using the molding die M2 configured as described above, first, as shown in FIG. 4, the mold frame 106 is separated from the second molding die 102 to the maximum. The tip of the protruding rod 108 is flush with the molding surface 102A of the second molding die 102, and the second molding die with respect to the first molding die 100 with the slide die 104 in close contact with the second molding die 102. 102 is closed. The first wall portion 20A and the first wall portion 20A are injected and solidified by injecting a required amount of the synthetic resin material into the cavity D including the molding recess 120 defined in the molding die M2. The second wall portion 20B is bent from the end edge of the second wall portion 20B toward the rear of the first wall portion 20A, and is bent inward from the rear end edge portion of the second wall portion 20B. The base material 20 provided with the third wall portion 20C is molded.

そして、キャビティＤで合成樹脂材料が固化したら、図５に示すように、第１成形型１００から第２成形型１０２を離間させ、成形型Ｍ２を型開きする。但し、成形型Ｍ２を型開きした段階では、基材２０の第２壁部分２０Ｂおよび第３壁部分２０Ｃの裏側にスライド型１０４が突出しているため、該基材２０は第２成形型１０２に保持されて脱型が不可能となっている。 When the synthetic resin material is solidified in the cavity D, as shown in FIG. 5, the second mold 102 is separated from the first mold 100, and the mold M2 is opened. However, when the mold M2 is opened, the slide mold 104 protrudes on the back side of the second wall portion 20B and the third wall portion 20C of the base material 20, so that the base material 20 is attached to the second mold die 102. It is held and demolding is impossible.

成形型Ｍ２の型開きが完了したら、図６に示すように、型フレーム１０６を第２成形型１０２に向けて移動させ、突出しロッド１０８を第２成形型１０２の成形面１０２Ａから突出させて基材２０の第１壁部分２０Ａを裏側から押すと共に、スライド型１０４を第２成形型１０２から延出させる。従って、突出しロッド１０８に押された基材２０は、第２成形型１０２の成形面１０２Ａから徐々に離間するようになる。 When the mold opening of the mold M2 is completed, as shown in FIG. 6, the mold frame 106 is moved toward the second mold 102, and the protruding rod 108 is protruded from the molding surface 102A of the second mold 102, so that the base While pushing the first wall portion 20 A of the material 20 from the back side, the slide mold 104 is extended from the second mold 102. Accordingly, the base material 20 pressed by the protruding rod 108 gradually separates from the molding surface 102A of the second molding die 102.

そして、成形完了した基材２０を第２成形型１０２から脱型するに際し、設置支持部４０の取付ボス４２およびスリット４４を成形する成形凹部１２０を設けたスライド型１０４が、第１壁部分２０Ａおよび第２壁部分２０Ｂの両方から相対的に離間する方向へ移動するので、該取付ボス４２およびスリット４４が、該スライド型１０４の移動方向を指向するように形成される。すなわち、第１壁部分２０Ａおよび第２壁部分２０Ｂの両方から相対的に離間するスライド型１０４の移動方向とは、図６に示すように、該第１壁部分２０Ａに対して斜め方向であるから、設置支持部４０の取付ボス４２およびスリット４４は、何れも第１壁部分２０Ａに対し傾斜し、かつ同一方向を指向するように形成される。 Then, when removing the molded base material 20 from the second mold 102, the slide mold 104 provided with the molding recess 120 for molding the mounting boss 42 and the slit 44 of the installation support portion 40 is the first wall portion 20A. The mounting boss 42 and the slit 44 are formed so as to be directed in the moving direction of the slide mold 104. That is, the moving direction of the slide mold 104 relatively spaced from both the first wall portion 20A and the second wall portion 20B is an oblique direction with respect to the first wall portion 20A as shown in FIG. Therefore, both the mounting boss 42 and the slit 44 of the installation support portion 40 are formed so as to be inclined with respect to the first wall portion 20A and directed in the same direction.

従って、実施例の製造方法によれば、次のような作用効果を奏する。すなわち、第１壁部分２０Ａの一部、第２壁部分２０Ｂおよび第３壁部分２０Ｃを成形するスライド型１０４に、取付ボス４２およびスリット４４からなる設置支持部４０を成形するための成形凹部１２０を設けたので、基材２０におけるアンダーカット形状を有する壁部の近くに、取付ボス４２およびスリット４４を設けることができる。また、スライド型１０４を、第１壁部分２０Ａおよび第２壁部分２０Ｂの両方から相対的に離間する方向へ移動させるため、成形凹部１２０により形成される設置支持部４０の取付ボス４２およびスリット４４を、第１壁部分２０Ａに対し傾斜し、かつ同一方向を指向するように形成し得る。そして、成形凹部１２０の第１成形部１２２により、タッピングネジＳをねじ込むことができる柱状突起状の取付ボス４２を成形すると共に、該成形凹部１２０の第２成形部１２４により、鉤状板部６６が係止可能な切り欠き状のスリット４４を成形するので、取付台座部材６０を基材２０へ確実に装着できるこれら取付ボス４２およびスリット４４を好適に成形し得る。 Therefore, according to the manufacturing method of the embodiment, the following operational effects can be obtained. That is, a molding recess 120 for molding the installation support portion 40 including the mounting boss 42 and the slit 44 in the slide mold 104 for molding a part of the first wall portion 20A, the second wall portion 20B, and the third wall portion 20C. Therefore, the mounting boss 42 and the slit 44 can be provided near the wall portion having the undercut shape in the base material 20. Further, in order to move the slide mold 104 in a direction relatively away from both the first wall portion 20A and the second wall portion 20B, the mounting boss 42 and the slit 44 of the installation support portion 40 formed by the molding concave portion 120 are used. May be inclined with respect to the first wall portion 20A and oriented in the same direction. Then, the columnar protrusion-shaped mounting boss 42 into which the tapping screw S can be screwed is formed by the first forming portion 122 of the forming recess 120, and the bowl-shaped plate portion 66 is formed by the second forming portion 124 of the forming recess 120. Since the notch-shaped slit 44 that can be locked is formed, the mounting boss 42 and the slit 44 that can securely attach the mounting base member 60 to the base member 20 can be suitably formed.

そして、実施例の成形型Ｍ２では、基材２０に対して相対的に移動するスライド型１０４の移動方向(第１壁部分２０Ａおよび第２壁部分２０Ｂの両方に対して相対的に離間する方向)は、型フレーム１０６に設けたガイドレール１０６Ａの傾斜角度によって規定されるため、該ガイドレール１０６Ａの角度設定を変更することで、形成される取付ボス４２およびスリット４４の指向方向を調整することが可能である。従って、実施例に係る車両内装部材１０の製造方法では、例えばガイドレール１０６Ａを第３壁部分２０Ｃと平行となる角度に設定した場合に、スライド型１０４を第３壁部分２０Ｃの折曲方向に沿う方向へ移動させることができるから、設置支持部４０における取付ボス４２およびスリット４４を、該第３壁部分２０Ｃの折曲方向と同一方向を指向するように成形することが可能である。取付ボス４２およびスリット４４を第３壁部分２０Ｃの折曲方向と同一方向を指向するように成形した場合には、該第３壁部分２０Ｃの折曲角度と同一方向から設置支持部４０に対して取付台座部材６０を取付けることができるから、例えば図２に示すように、第２壁部分２０Ｂに対する第３壁部分２０Ｃの折曲角度が小さくて該第３壁部分２０Ｃが立ち上がった形状である場合には、取付ボス４２およびスリット４４も第１壁部分２０Ａに対して立ち上がった姿勢となって裏側開口部２１を指向するようになるので、設置支持部４０に対する取付台座部材６０の装着作業を行ない易くなる。 And in the shaping | molding die M2 of an Example, the moving direction (direction relatively spaced with respect to both the 1st wall part 20A and the 2nd wall part 20B) of the slide type | mold 104 which moves relatively with respect to the base material 20 ) Is defined by the inclination angle of the guide rail 106A provided on the mold frame 106, and by changing the angle setting of the guide rail 106A, the orientation direction of the mounting boss 42 and the slit 44 to be formed can be adjusted. Is possible. Therefore, in the method for manufacturing the vehicle interior member 10 according to the embodiment, for example, when the guide rail 106A is set at an angle parallel to the third wall portion 20C, the slide mold 104 is set in the bending direction of the third wall portion 20C. Since the mounting boss 42 and the slit 44 in the installation support portion 40 can be moved in the direction along the direction, the mounting boss 42 and the slit 44 can be shaped so as to be directed in the same direction as the bending direction of the third wall portion 20C. When the mounting boss 42 and the slit 44 are formed so as to be oriented in the same direction as the bending direction of the third wall portion 20C, the mounting boss 42 and the slit 44 are directed to the installation support portion 40 from the same direction as the bending angle of the third wall portion 20C. Thus, the mounting base member 60 can be attached, for example, as shown in FIG. 2, the bending angle of the third wall portion 20C with respect to the second wall portion 20B is small and the third wall portion 20C rises. In this case, since the mounting boss 42 and the slit 44 are also raised with respect to the first wall portion 20A and are directed to the back side opening 21, the mounting work of mounting the mounting base member 60 on the installation support 40 is performed. It becomes easy to do.

一方、成形型Ｍ２のスライド型１０４に、取付ボス４２を成形する第１成形部１２２およびスリット４４を成形する第２成形部１２４からなる成形凹部１２０を設けると共に、該第１成形部１２２を第２壁部分２０Ｂの裏側に臨む位置に設けると共に、該第２成形部１２４を第１成形部１２２より第１壁部分２０Ａに近い位置に設けた。従って、前述した成形型Ｍ２により成形された実施例の車両内装部材１０の基材２０は、図１に示すように、設置支持部４０の取付ボス４２が第２壁部分２０Ｂの裏側に設けられると共に、該設置支持部４０のスリット４４が該取付ボス４２より第１壁部分２０Ａに近い位置に設けられている。更に設置支持部４０は、第１壁部分２０Ａから第２壁部分２０Ｂに亘って位置している。従って、設置支持部４０に装着した取付台座部材６０は、第２壁部分２０Ｂおよび第３壁部分２０Ｃに隣接して基材２０の裏側に取付けられるから、該取付台座部材６０に装着されたクリップＣの位置を、第２壁部分２０Ｂおよび第３壁部分２０Ｃに近接させることができ、第３壁部分２０ＣとクリップＣとの間隔Ｌを小さくできる。 On the other hand, the slide mold 104 of the mold M2 is provided with a molding recess 120 including a first molding part 122 that molds the mounting boss 42 and a second molding part 124 that molds the slit 44, and the first molding part 122 is The second molded part 124 was provided at a position closer to the first wall part 20A than the first molded part 122, while being provided at a position facing the back side of the two wall part 20B. Therefore, as shown in FIG. 1, the base material 20 of the vehicle interior member 10 of the embodiment molded by the molding die M2 described above is provided with the mounting boss 42 of the installation support portion 40 on the back side of the second wall portion 20B. In addition, the slit 44 of the installation support portion 40 is provided at a position closer to the first wall portion 20 A than the mounting boss 42. Furthermore, the installation support portion 40 is located from the first wall portion 20A to the second wall portion 20B. Therefore, since the mounting base member 60 mounted on the installation support portion 40 is mounted on the back side of the base material 20 adjacent to the second wall portion 20B and the third wall portion 20C, the clip mounted on the mounting base member 60 The position of C can be brought close to the second wall portion 20B and the third wall portion 20C, and the distance L between the third wall portion 20C and the clip C can be reduced.

また、設置支持部４０の取付ボス４２およびスリット４４が、第１壁部分２０Ａの裏側に対し傾斜し、かつ同一方向を指向するように設けられているため、裏側開口部２１から設置支持部４０に対して取付台座部材６０を斜めに装着することができ、設置支持部４０に対する取付台座部材６０のセット作業を行ない易い。更に、取付ボス４２よりスリット４４が第１壁部分に近いところに位置していることにより、取付ボス４２の締結作業をスリット４４の影響を受けることなく行なうことができるため、取付ボス４２に対するタッピングネジＳのねじ込み作業を行ない易く、取付台座部材６０の装着作業の簡易化を図り得る。しかも、タッピングネジＳを取付ボス４２へねじ込むと共に鉤状板部６６をスリット４４へ係止させるため、設置支持部４０に対して取付台座部材６０を確実に装着し得る。 Further, since the mounting boss 42 and the slit 44 of the installation support part 40 are provided so as to be inclined with respect to the back side of the first wall portion 20A and directed in the same direction, the installation support part 40 from the back side opening 21. The mounting base member 60 can be mounted obliquely with respect to the mounting support member 40 and the mounting base member 60 can be easily set. Further, since the slit 44 is positioned closer to the first wall portion than the mounting boss 42, the fastening operation of the mounting boss 42 can be performed without being affected by the slit 44. The screw S can be easily screwed in, and the mounting work of the mounting base member 60 can be simplified. Moreover, since the tapping screw S is screwed into the mounting boss 42 and the hooked plate portion 66 is locked to the slit 44, the mounting base member 60 can be securely mounted to the installation support portion 40.

また、スリット４４と鉤状板部６６との嵌合位置(スリット４４の形成位置)と、取付台座部材６０に対するクリップＣの装着位置とが、車体Ｂに対する該クリップＣの組付け方向Ｑに沿う直線上に臨んでいる。従って、基材２０を車体Ｂから取外す際は、取付台座部材６０に作用する力をリブ５２の第２当接部５２Ｂで受け止めるようになるため、設置支持部４０に対する該取付台座部材６０の装着状態を好適に維持できる。また、車体Ｂに対して基材２０を取付ける際は、基材２０の第１壁部分２０Ａに加えた押圧力がリブ５２の第１当接部５２Ａを介して取付台座部材６０に作用するため、係止孔Ｂ１に対してクリップＣを適切に嵌合させ得る。 Further, the fitting position (the formation position of the slit 44) between the slit 44 and the bowl-shaped plate portion 66 and the mounting position of the clip C with respect to the mounting base member 60 are along the assembly direction Q of the clip C with respect to the vehicle body B. It faces a straight line. Therefore, when the base member 20 is removed from the vehicle body B, the force acting on the mounting base member 60 is received by the second abutting portion 52B of the rib 52, so that the mounting base member 60 is attached to the installation support portion 40. The state can be suitably maintained. Further, when the base material 20 is attached to the vehicle body B, the pressing force applied to the first wall portion 20 A of the base material 20 acts on the mounting base member 60 via the first contact portion 52 A of the rib 52. The clip C can be appropriately fitted to the locking hole B1.

更に、実施例に係る車両内装部材１０の製造方法では、図９に示すように、スライド型１０４における成形凹部１２０の形成位置を、第２壁部分２０Ｂに対応した該スライド型１０４の型面における垂直部分とすれば、図８に示すように、第２壁部分２０Ｂの裏側に位置するように設置支持部４０を設けることが可能である。すなわち、設置支持部４０の取付ボス４２を、第２壁部分２０Ｂの裏側に位置するように設け、スリット４４は、該取付ボス４２より第１壁部分２０Ａに近い位置で、かつ該第２壁部分２０Ｂの裏側に位置するように設けることができる。 Furthermore, in the method for manufacturing the vehicle interior member 10 according to the embodiment, as shown in FIG. 9, the formation position of the molding recess 120 in the slide mold 104 is set on the mold surface of the slide mold 104 corresponding to the second wall portion 20B. If it is a vertical part, as shown in FIG. 8, it is possible to provide the installation support part 40 so that it may be located in the back side of the 2nd wall part 20B. That is, the mounting boss 42 of the installation support part 40 is provided so as to be positioned on the back side of the second wall portion 20B, and the slit 44 is closer to the first wall portion 20A than the mounting boss 42 and the second wall. It can provide so that it may be located in the back side of the part 20B.

更に、実施例に係る車両内装部材１０の製造方法では、図１０に示すように、スライド型１０４における成形凹部１２０の形成位置を、第１壁部分２０Ａに対応した該スライド型１０４の型面における水平部分とすれば、第１壁部分２０Ａの裏側に位置するように設置支持部４０を設けることが可能である。すなわち、設置支持部４０の取付ボス４２を、第１壁部分２０Ａの裏側に位置するように設け、スリット４４は、該取付ボス４２より第２壁部分２０Ｂから遠い位置で、かつ該第１壁部分２０Ａの裏側に位置するように設けることができる。 Further, in the method for manufacturing the vehicle interior member 10 according to the embodiment, as shown in FIG. 10, the formation position of the molding recess 120 in the slide mold 104 is set on the mold surface of the slide mold 104 corresponding to the first wall portion 20A. If it is a horizontal part, it is possible to provide the installation support part 40 so that it may be located in the back side of 20 A of 1st wall parts. That is, the mounting boss 42 of the installation support portion 40 is provided so as to be positioned on the back side of the first wall portion 20A, and the slit 44 is located farther from the second wall portion 20B than the mounting boss 42 and the first wall. It can provide so that it may be located in the back side of the part 20A.

更にまた、実施例に係る車両内装部材１０の製造方法では、図４に示した成形型Ｍ２において、スライド型１０４に設けた成形凹部１２０における第１成形部１２２および第２成形部１２４の位置を逆にすれば、設置支持部４０のスリット４４を、第２壁部分２０Ｂの裏側に設けると共に、取付ボス４２を、該スリット４４よりも第１壁部分２０Ａに近い位置に設けることができる。また、図９に示した成形型Ｍ２において、スライド型１０４に設けた成形凹部１２０における第１成形部１２２および第２成形部１２４の位置を逆にすれば、設置支持部４０のスリット４４を、第２壁部分２０Ｂの裏側に設けると共に、取付ボス４２を、該スリット４４より第１壁部分２０Ａに近い位置で、かつ該第２壁部分２０Ｂの裏側に位置するように設けることができる。一方、図１０に示した成形型Ｍ２において、スライド型１０４に設けた成形凹部１２０における第１成形部１２２および第２成形部１２４の位置を逆にすれば、設置支持部４０のスリット４４を、第１壁部分２０Ａの裏側に位置するように設け、取付ボス４２を、該スリット４４より第２壁部分２０Ｂから遠い位置で、かつ該第１壁部分２０Ａの裏側に位置するように設けることができる。 Furthermore, in the method for manufacturing the vehicle interior member 10 according to the embodiment, the positions of the first molding part 122 and the second molding part 124 in the molding recess 120 provided in the slide mold 104 in the molding die M2 shown in FIG. In other words, the slit 44 of the installation support part 40 can be provided on the back side of the second wall portion 20B, and the mounting boss 42 can be provided at a position closer to the first wall portion 20A than the slit 44. In the molding die M2 shown in FIG. 9, if the positions of the first molding part 122 and the second molding part 124 in the molding recess 120 provided in the slide mold 104 are reversed, the slit 44 of the installation support part 40 is In addition to being provided on the back side of the second wall portion 20B, the mounting boss 42 can be provided at a position closer to the first wall portion 20A than the slit 44 and on the back side of the second wall portion 20B. On the other hand, in the molding die M2 shown in FIG. 10, if the positions of the first molding portion 122 and the second molding portion 124 in the molding recess 120 provided in the slide die 104 are reversed, the slit 44 of the installation support portion 40 is It is provided so as to be located on the back side of the first wall portion 20A, and the mounting boss 42 is provided so as to be located farther from the second wall portion 20B than the slit 44 and on the back side of the first wall portion 20A. it can.

また、第２壁部分２０Ｂに対する第３壁部分２０Ｃの折曲角度が小さくて該第３壁部分２０Ｃが立ち上がった形状であり、かつスライド型１０４の移動方向が該第３壁部分２０Ｃの折曲方向との間に所要の角度差がある場合は、第３壁部分２０Ｃに対応するスライド型１０４の壁面に臨むように成形凹部１２０を設ければ、第３壁部分２０Ｃの裏側に、取付ボス４２またはスリット４４を形成することも可能とし得る。 Further, the third wall portion 20C has a small bending angle with respect to the second wall portion 20B, and the third wall portion 20C rises, and the moving direction of the slide mold 104 is the bending of the third wall portion 20C. If there is a required angle difference with the direction, if the molding recess 120 is provided so as to face the wall surface of the slide mold 104 corresponding to the third wall portion 20C, a mounting boss is provided on the back side of the third wall portion 20C. It may also be possible to form 42 or slits 44.

換言すると、実施例に係る車両内装部材１０の製造方法は、スライド型１０４に成形凹部１２０を設けたことにより、基材２０の裏面において該スライド型１０４が対応する位置であれば、設置支持部４０における取付ボス４２およびスリット４４を、第１壁部分２０Ａに対して傾斜し、かつ同一方向を指向するように形成し得る。特にスライド型１０４は、基材２０におけるアンダーカット形状を有する壁部を成形するため、設置支持部４０の取付ボス４２およびスリット４４を、基材２０におけるアンダーカット形状を有する壁部の近くに設けることができる。 In other words, in the method for manufacturing the vehicle interior member 10 according to the embodiment, the installation support portion is provided as long as the slide mold 104 is located on the back surface of the base material 20 by providing the slide mold 104 with the molding recess 120.
