発泡成形品の製造時には、発泡成形用の成形型に予めクリップなどの部品を取付けておき、その状態で、発泡樹脂を成形型に注入して成形することで、部品が埋設された状態の発泡樹脂成形品が得られる。上述の部品を成形型に取付ける方法としては、例えば下記特許文献１に記載されるものがある。この特許文献１に記載される発泡成形品製造方法では、部品を部品設置用治具に仮止めし、その治具を成形型の規定位置に設置してから発泡樹脂を注入し、発泡樹脂成形品を成形型から脱型した後、部品設置用治具を除去する工程が行われている。 At the time of manufacturing a foam molded product, parts such as clips are attached to the mold for foam molding in advance, and in that state, foam resin is injected into the mold and molded, so that the parts are embedded. A resin molded product can be obtained. As a method for attaching the above-mentioned parts to a molding die, for example, there is one described in Patent Document 1 below. In the foam molded product manufacturing method described in Patent Document 1, parts are temporarily fixed to a jig for component installation, the jig is installed at a specified position of a molding mold, and then foam resin is injected to mold the foam resin. After the product is removed from the mold, a process of removing the jig for installing parts is performed.

以下に、本発明の部品取付治具の一実施の形態について図面を参照して詳細に説明する。図１は、この実施の形態の部品取付治具の斜視図であり、例えばＡＢＳ樹脂やポリプロピレン、ポリアミドなどの樹脂材料からなる一体（一連）の治具基体２１を有する。この治具基体２１は、コ字状枠の両側部の中間部が連結杆で連結された一連の厚板部材からなり、図の下面は、後述する全ての部品装着位置に対向する対向面２１ａを構成している。この対向面２１ａには、後述する部品仮保持部材３が複数取付けられ、それらの部品仮保持部材３は、後述する発泡樹脂成形品用の成形型４への部品の取付位置（部品装着位置）に配置されている。一方、この治具基体２１の対向面２１ａと反対側の面（以下、反対面と記す）２１ｂ上には、例えば作業者が両手の夫々で把持するためのは取っ手１が設けられている。この実施の形態では、治具基体２１のコ字状枠の両側部の夫々に、取っ手１が１つずつ２個一対で取付けられている。従って、２個一対の取っ手１は治具基体２１の両側に対向配置されており、この一対の取っ手１の並び方向を取っ手並び方向と規定する。なお、この治具基体２１には、反対面２１ｂから対向面２１ａまで貫通する複数の貫通開口部１４が形成されているが、その目的については後述する。また、治具基体２１の形状や材質は、上記に限定されるものではない。 Hereinafter, an embodiment of the component mounting jig of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of the component mounting jig of this embodiment, and has an integral (series) jig base 21 made of a resin material such as ABS resin, polypropylene, or polyamide. The jig base 21 is composed of a series of thick plate members in which intermediate portions on both sides of a U-shaped frame are connected by a connecting rod, and the lower surface of the figure is a facing surface 21a facing all component mounting positions described later. Consists of. A plurality of component temporary holding members 3 to be described later are attached to the facing surface 21a, and the component temporary holding members 3 are the component mounting positions (component mounting positions) on the molding die 4 for the foamed resin molded product described later. Is located in. On the other hand, on the surface of the jig base 21 opposite to the facing surface 21a (hereinafter referred to as the opposite surface) 21b, for example, a handle 1 is provided for the operator to grip with both hands. In this embodiment, two handles 1 are attached to each of both sides of the U-shaped frame of the jig base 21 in pairs. Therefore, the pair of handles 1 are arranged to face each other on both sides of the jig base 21, and the arrangement direction of the pair of handles 1 is defined as the arrangement direction of the handles. The jig substrate 21 is formed with a plurality of through openings 14 penetrating from the opposite surface 21b to the facing surface 21a, and the purpose thereof will be described later. Further, the shape and material of the jig base 21 are not limited to the above.

図２は、発泡樹脂成形品用の成形型４と、それに取付けられる部品の斜視図である。この実施の形態では、例えば発泡樹脂成形品の表面に表皮材を取付けるためのクリップ５を成形型４に取付ける部品とし、このクリップ５を図示しない発泡樹脂成形品の溝部の底部に埋設する。このクリップ５には係止部６が形成されており、この係止部６に表皮材の係止具を係止することで発泡樹脂成形品の表面に表皮材が装着される。 FIG. 2 is a perspective view of a molding die 4 for a foamed resin molded product and parts attached to the molding die 4. In this embodiment, for example, a clip 5 for attaching the skin material to the surface of the foamed resin molded product is used as a component to be attached to the molding mold 4, and the clip 5 is embedded in the bottom of a groove portion of the foamed resin molded product (not shown). A locking portion 6 is formed on the clip 5, and the skin material is attached to the surface of the foamed resin molded product by locking the locking tool of the skin material to the locking portion 6.

発泡樹脂成形品用の成形型４には、発泡樹脂成形品に溝部を形成するためのリブ状突起部７が形成されている。このリブ状突起部７には、発泡樹脂成形品の規定位置にクリップ５を埋設することを主目的として幅狭部８が形成されている。この幅狭部８は、リブ状突起部７の突出先端部の幅方向両端部を部分的に略方形に窪ませて幅狭に形成されている。この幅狭部８は、部品であるクリップ５を係止するための部品装着位置を構成し、この幅狭部８にクリップ５の係止部６を係止して成形型４にクリップ５を取付ける。そして、その状態で、成形型４に発泡樹脂を注入して成形することで、クリップ５が発泡樹脂成形品の規定位置、つまり溝部の底部に埋設された状態とする。 The molding die 4 for the foamed resin molded product is formed with a rib-shaped protrusion 7 for forming a groove in the foamed resin molded product. A narrow portion 8 is formed in the rib-shaped protrusion 7 mainly for the purpose of embedding the clip 5 at a predetermined position of the foamed resin molded product. The narrow portion 8 is formed to be narrow by partially recessing both ends in the width direction of the protruding tip portion of the rib-shaped protrusion 7. The narrow portion 8 constitutes a component mounting position for locking the clip 5, which is a component, and the locking portion 6 of the clip 5 is locked to the narrow portion 8 to attach the clip 5 to the molding die 4. Install. Then, in that state, the foamed resin is injected into the molding die 4 and molded so that the clip 5 is embedded in the specified position of the foamed resin molded product, that is, at the bottom of the groove portion.

図３は、部品であるクリップ５の詳細説明図であり、（ａ）は斜視図、（ｂ）は平面図、（ｃ）は正面図、（ｄ）は側面図である。このクリップ５は、例えば樹脂材料からなり、方形平板状の基底部９を有し、この基底部９の一方の面から互いに逆向きの斜め垂直方向に突出する一対の係止部６が基底部６と一体に形成されている。この一対の係止部６の突出先端部には、互いに対向する爪部１０が対向方向に突出形成され、この爪部１０が、成形型４のリブ状突起部７の幅狭部８に係合することでクリップ５が幅狭部８に係止される。 3A and 3B are detailed explanatory views of the clip 5, which is a component, FIG. 3A is a perspective view, FIG. 3B is a plan view, FIG. 3C is a front view, and FIG. 3D is a side view. The clip 5 is made of, for example, a resin material, has a square flat plate-shaped base portion 9, and has a pair of locking portions 6 projecting from one surface of the base portion 9 in diagonally vertical directions opposite to each other. It is integrally formed with 6. On the protruding tip portions of the pair of locking portions 6, the claw portions 10 facing each other are formed so as to project in opposite directions, and the claw portions 10 are engaged with the narrow portion 8 of the rib-shaped protruding portions 7 of the molding die 4. By fitting, the clip 5 is locked to the narrow portion 8.

従って、このクリップ５は、一対の係止部６間の隙間にリブ状突起部７の幅狭部８を押し込むと係止部６が幅狭部８に係止する。つまり、この一対の係止部６の突設方向がクリップ５の成形型４への取付方向（後述する部品仮保持部材３の収容部１１からのクリップ５の抜去方向と同じ）に相当する。また、幅狭部８のリブ形状を挟むように一対の係止部６を配置すると共に、係止部６を挟んでリブ状突起部７と反対側に基底部９が配置されるクリップ５の姿勢が、後述する部品仮保持部材３におけるクリップ５の規定姿勢となる。なお、以下では、係止部６が突設されている基底部９の一方の面を表面とも記し、その反対側の面を裏面とも記す。 Therefore, in this clip 5, when the narrow portion 8 of the rib-shaped protrusion 7 is pushed into the gap between the pair of locking portions 6, the locking portion 6 is locked to the narrow portion 8. That is, the projecting direction of the pair of locking portions 6 corresponds to the mounting direction of the clip 5 to the molding die 4 (the same as the removing direction of the clip 5 from the accommodating portion 11 of the component temporary holding member 3 described later). Further, a clip 5 in which a pair of locking portions 6 are arranged so as to sandwich the rib shape of the narrow portion 8 and a base portion 9 is arranged on the opposite side of the rib-shaped protrusion 7 with the locking portion 6 interposed therebetween. The posture is the defined posture of the clip 5 in the component temporary holding member 3, which will be described later. In the following, one surface of the base portion 9 on which the locking portion 6 is projected is also referred to as a front surface, and the opposite surface thereof is also referred to as a back surface.

図４は、図１の部品仮保持部材３の斜視図である。また、図５は、図４の部品仮保持部材３の三面図であり、（ａ）は平面図、（ｂ）は（ａ）のＡ−Ａ断面図である。また、図６は、図４の部品仮保持部材３に部品であるクリップ５を仮保持した状態の斜視図である。この部品仮保持部材３は、クリップ５を規定の保持力で仮保持する仮保持部２を有する。この仮保持部２は、一対の梁状壁部１３の内側にクリップ５を規定姿勢で収容する収容部１１を有する。 FIG. 4 is a perspective view of the component temporary holding member 3 of FIG. 5A and 5B are three views of the temporary holding member 3 of FIG. 4, where FIG. 5A is a plan view and FIG. 5B is a sectional view taken along the line AA of FIG. 4A. Further, FIG. 6 is a perspective view showing a state in which the clip 5, which is a component, is temporarily held by the component temporary holding member 3 of FIG. The component temporary holding member 3 has a temporary holding portion 2 that temporarily holds the clip 5 with a predetermined holding force. The temporary holding portion 2 has an accommodating portion 11 that accommodates the clip 5 in a predetermined posture inside the pair of beam-shaped wall portions 13.

この収容部１１は、長手方向中央部の図示下部が連結基底部１２で一体に連結された互いに平行な２本の梁状の壁部１３の内側に形成される。この実施の形態における収容部１１内のクリップ５の規定姿勢は、クリップ５の基底部９が収容部１１の連結基底部１２側になり且つ対をなす係止部６の対向方向が壁部１３の対向方向となる姿勢を示す。従って、この収容部１１では、クリップ５の基底部９の裏面が連結基底部１２に当接する。 The accommodating portion 11 is formed inside two beam-shaped wall portions 13 parallel to each other in which the lower part of the drawing in the central portion in the longitudinal direction is integrally connected by the connecting base portion 12. In the defined posture of the clip 5 in the accommodating portion 11 in this embodiment, the base portion 9 of the clip 5 is on the connecting base portion 12 side of the accommodating portion 11, and the facing direction of the paired locking portions 6 is the wall portion 13. Indicates the posture in the opposite direction of. Therefore, in the accommodating portion 11, the back surface of the base portion 9 of the clip 5 abuts on the connecting base portion 12.

この２本の梁状の壁部１３の対向面の長手方向両端部近傍の計４カ所には、互いに対向する位置に円穴１５が形成され、この円穴１５内に、本発明の挟持手段を構成するボールプランジャ１６が圧入されている。つまり、この実施の形態の仮保持部２は、収容部１１とボールプランジャ（挟持手段）１６を備えて構成される。このボールプランジャ１６は、例えば図７に示すように、有底円筒状のケース１７内に付勢手段であるコイルスプリング１８が内装され、その一方の端部、つまりケース１７の開口端部側に、球状体であるボール１９が配設されている。このボール１９の一部はケース１７からコイルスプリング１８の付勢方向外側に突出されている。 Circular holes 15 are formed at positions facing each other at a total of four locations near both ends of the facing surfaces of the two beam-shaped wall portions 13 in the longitudinal direction, and the holding means of the present invention is formed in the circular holes 15. The ball plunger 16 constituting the above is press-fitted. That is, the temporary holding portion 2 of this embodiment is configured to include the accommodating portion 11 and the ball plunger (pinching means) 16. In the ball plunger 16, for example, as shown in FIG. 7, a coil spring 18 as a urging means is housed in a bottomed cylindrical case 17, and one end thereof, that is, the open end side of the case 17 is provided. , The ball 19 which is a spherical body is arranged. A part of the ball 19 is projected from the case 17 to the outside in the biasing direction of the coil spring 18.

また、そのボール１９の球面のうち、ケース１７の径方向外側端部の部分がケース１７の開口端部の内周縁部に形成された規制部２０で規制されて、それ以上、突出しないように構成されている。即ち、ボールプランジャ１６のボール１９はケース１７の規制部２０で規制された位置を最外位置として、それよりケース１７内に押し込まれる方向にのみ移動する。ボール１９を押し込んだ位置におけるコイルスプリング１８によるボール押力（付勢力）は、コイルスプリング１８の自由長からの変位とコイルスプリング１８のばね定数から求められる。なお、ケース１７の開口端部外周縁には、ボールプランジャ１６の円穴１５内への圧入位置を規定するフランジ部１７ａが形成されている。つまり、このフランジ部１７ａが２つの壁部１３の夫々の対向面に当接してボールプランジャ１６の圧入位置が規定される。 Further, of the spherical surface of the ball 19, the portion of the radial outer end portion of the case 17 is regulated by the regulating portion 20 formed on the inner peripheral edge portion of the opening end portion of the case 17, so that the ball 19 does not protrude any more. It is configured. That is, the ball 19 of the ball plunger 16 moves only in the direction of being pushed into the case 17 from the position regulated by the regulating portion 20 of the case 17 as the outermost position. The ball pushing force (urging force) by the coil spring 18 at the position where the ball 19 is pushed is obtained from the displacement of the coil spring 18 from the free length and the spring constant of the coil spring 18. A flange portion 17a that defines a press-fitting position of the ball plunger 16 into the circular hole 15 is formed on the outer peripheral edge of the opening end of the case 17. That is, the flange portion 17a abuts on the facing surfaces of the two wall portions 13, and the press-fitting position of the ball plunger 16 is defined.

このボールプランジャ１６（具体的にはケース１７）を、対向する壁部１３の円穴１５内に互いに対向するように圧入することにより、収容部１１には２個一対のボールプランジャ１６のボール１９が互いに正対するように対向して壁部１３の対向面から突出する。従って、この実施の形態では、収容部１１内にクリップ５を規定姿勢で収容すると、対向するボールプランジャ１６のボール１９に基底部９が当接する。その状態から、さらにクリップ５を対向するボール１９間に押し込むと、ボール１９が基底部９でケース１７内に押し込まれる。そして、クリップ５の収容部１１への収容状態で発生するコイルスプリング１８の付勢力がボール１９に付与され、対向するボールプランジャ１６で（正確には連結基底部１２と共に）クリップ５の基底部９が挟まれてクリップ５が仮保持される。つまり、この状態で、クリップ５は規定姿勢で仮保持部２に仮保持される。なお、このクリップ５の収容部１１への収容状態を、単にクリップ収容状態とも記す。 By press-fitting the ball plunger 16 (specifically, the case 17) into the circular holes 15 of the facing wall portions 13 so as to face each other, the balls 19 of the pair of ball plungers 16 are inserted into the accommodating portion 11. Are facing each other so as to face each other and project from the facing surface of the wall portion 13. Therefore, in this embodiment, when the clip 5 is accommodated in the accommodating portion 11 in a predetermined posture, the base portion 9 comes into contact with the balls 19 of the opposing ball plungers 16. From that state, when the clip 5 is further pushed between the opposing balls 19, the balls 19 are pushed into the case 17 at the base portion 9. Then, the urging force of the coil spring 18 generated in the accommodating state of the clip 5 in the accommodating portion 11 is applied to the ball 19, and the base portion 9 of the clip 5 (to be exact, together with the connecting base portion 12) is applied to the ball 19. Is sandwiched and the clip 5 is temporarily held. That is, in this state, the clip 5 is temporarily held by the temporary holding portion 2 in the specified posture. In addition, the state of accommodating the clip 5 in the accommodating portion 11 is also simply referred to as a clip accommodating state.

このように構成された部品仮保持部材３を、例えば図２の幅狭部８に対向するように治具基体２１の対向面２１ａに複数個取付けて図１に示す部品取付治具が構成される。部品仮保持部材３は、連結基底部１２が対向面２１ａ側になるようにすることで収容部１１が開口するようにして治具基体２１の対向面２１ａに取付けられる。この実施の形態では、これら複数の部品仮保持部材３は、発泡樹脂成形品における全てのクリップ５の規定位置に対応する配置で装着される。 A plurality of the component temporary holding members 3 configured in this way are attached to the facing surface 21a of the jig substrate 21 so as to face the narrow portion 8 of FIG. 2, for example, to form the component mounting jig shown in FIG. NS. The component temporary holding member 3 is attached to the facing surface 21a of the jig base 21 so that the accommodating portion 11 is opened by making the connecting base portion 12 on the facing surface 21a side. In this embodiment, these plurality of temporary component holding members 3 are mounted in an arrangement corresponding to the specified positions of all the clips 5 in the foamed resin molded product.

この実施の形態では、図８（ａ）に示すように、部品仮保持部材３の仮保持部２によってクリップ５が規定姿勢で仮保持されている状態で、例えば２個一対の取っ手１の夫々を両手の夫々で把持して、図８（ｂ）に示すように、部品取付治具の治具基体２１を成形型４に押し付ける。これにより、クリップ５の係止部６がリブ状突起部７の幅狭部８（図８（ｂ）では見えていない）に係止するので、その後、図８（ｃ）に示すように、治具基体２１を成形型４から離間することで部品仮保持部材３自体を成形型４から離反させる。その際、係止部６が幅狭部８に係止したままクリップ５が部品仮保持部材３の仮保持部２から抜去され、クリップ５だけが成形型４に残存することで、クリップ５が成形型４に取付けられた状態を維持する。 In this embodiment, as shown in FIG. 8A, the clip 5 is temporarily held in a predetermined posture by the temporary holding portion 2 of the temporary holding member 3, for example, two pairs of handles 1 respectively. Is grasped by both hands, and as shown in FIG. 8B, the jig base 21 of the component mounting jig is pressed against the molding die 4. As a result, the locking portion 6 of the clip 5 is locked to the narrow portion 8 of the rib-shaped protrusion 7 (not visible in FIG. 8B), and thereafter, as shown in FIG. 8C, By separating the jig base 21 from the molding die 4, the component temporary holding member 3 itself is separated from the molding die 4. At that time, the clip 5 is removed from the temporary holding portion 2 of the component temporary holding member 3 while the locking portion 6 is locked to the narrow portion 8, and only the clip 5 remains in the molding die 4, so that the clip 5 is formed. The state of being attached to the molding die 4 is maintained.

そのため、後述するように、付勢手段を構成するコイルスプリング１８によってボール１９に付与されるクリップ５の保持力が、係止部６と幅狭部８との係止力より小さくなるように構成する。また、前述のように、冶具基体２１の対向面２１ａには、リブ状突起部７の全ての幅狭部８と対向する位置に部品仮保持部材３が取付けられているので、冶具基体２１を成形型４に押し付けるだけで、全ての幅狭部８、即ち部品装着位置にクリップ５が取付けられる。なお、この実施の形態では、挟持手段であるボールプランジャ１６が収容部１１の対向する壁部１３に設けられているので、クリップ５の成形型４への係止動作が妨げられることがない。 Therefore, as will be described later, the holding force of the clip 5 applied to the ball 19 by the coil spring 18 constituting the urging means is configured to be smaller than the locking force between the locking portion 6 and the narrow portion 8. do. Further, as described above, since the component temporary holding member 3 is attached to the facing surface 21a of the jig base 21 at a position facing all the narrow portions 8 of the rib-shaped protrusions 7, the jig base 21 can be used. The clip 5 is attached to all the narrow portions 8, that is, the component mounting positions, simply by pressing against the molding die 4. In this embodiment, since the ball plunger 16 as a holding means is provided on the facing wall portion 13 of the accommodating portion 11, the locking operation of the clip 5 to the molding die 4 is not hindered.

クリップ５の係止部６と成形型４の幅狭部８との係止力は予め判明しており（即ち規定値）、前述したように、コイルスプリング１８によるボール１９の押力、つまりコイルスプリング１８によってボール１９に付与される付勢力も算出可能である。この実施形態のボールプランジャ１６によるクリップ５の保持力は、単純に計算するならば、コイルスプリング１８によるボール１９の付勢力、つまり抗力と、ボール１９−基底部９間の摩擦係数との積値で得られる。 The locking force between the locking portion 6 of the clip 5 and the narrow portion 8 of the molding die 4 is known in advance (that is, a specified value), and as described above, the pushing force of the ball 19 by the coil spring 18, that is, the coil. The urging force applied to the ball 19 by the spring 18 can also be calculated. The holding force of the clip 5 by the ball plunger 16 of this embodiment is, if calculated simply, the product value of the urging force, that is, the drag force of the ball 19 by the coil spring 18 and the friction coefficient between the ball 19 and the base portion 9. Obtained at.

従って、例えばボール１９による基底部９の仮保持状態でのコイルスプリング１８の変位や、対向するボール１９間から基底部９を抜去する際に生じるコイルスプリング１８の変位から保持力の最大値が求まる。この保持力の最大値が係止部６と幅狭部８との係止力より小さくなるようにコイルスプリング１８の変位やばね定数を設定し、それらに応じてボールプランジャ１６（コイルスプリング１８）を選定したり、ボールプランジャ１６の位置を決定したりする。 Therefore, for example, the maximum value of the holding force can be obtained from the displacement of the coil spring 18 in the temporary holding state of the base portion 9 by the balls 19 and the displacement of the coil spring 18 generated when the base portion 9 is removed from the opposing balls 19. .. The displacement and spring constant of the coil spring 18 are set so that the maximum value of this holding force is smaller than the locking force between the locking portion 6 and the narrow portion 8, and the ball plunger 16 (coil spring 18) is set accordingly. And determine the position of the ball plunger 16.

この実施の形態では、ボールプランジャ１６のボール１９は収容部１１の対向する壁部１３の対向面から突出し、この壁部１３の近傍でクリップ５の基底部９に当接する。前述のように、成形型４からの収容部１１の離反時にクリップ５は仮保持部２から抜去されるが、ボール１９は壁部１３の近傍でクリップ５に当接しているため、その抜去動作が妨げられることがない。また、クリップ５の基底部９に接触するボール１９の球面は、接触する対象との接触面積が小さい。そのため、この実施の形態のように、ボール１９に対してクリップ５の基底部９を滑らせるようにして仮保持部２からクリップ５を抜去する場合であってもクリップ５を抜去し易い。 In this embodiment, the ball 19 of the ball plunger 16 projects from the facing surface of the facing wall portion 13 of the accommodating portion 11 and abuts on the base portion 9 of the clip 5 in the vicinity of the wall portion 13. As described above, the clip 5 is removed from the temporary holding portion 2 when the accommodating portion 11 is separated from the molding die 4, but since the ball 19 is in contact with the clip 5 in the vicinity of the wall portion 13, the removal operation thereof is performed. Is not disturbed. Further, the spherical surface of the ball 19 that contacts the base portion 9 of the clip 5 has a small contact area with the object to be contacted. Therefore, even when the clip 5 is removed from the temporary holding portion 2 by sliding the base portion 9 of the clip 5 with respect to the ball 19 as in this embodiment, the clip 5 can be easily removed.

また、この実施の形態では、コイルスプリング１８からなる付勢手段は、クリップ５を成形型４から離反する方向に対して交差する方向に付勢力を発生する。この付勢力が、クリップ５を仮保持する仮保持部２の保持力となる。このクリップ保持力がクリップ５を成形型４から離反する方向と同方向であると、収容部１１を成形型４から離反させる際、仮保持部２からクリップ５を抜去しにくくなる。逆にクリップ保持力がクリップ５を成形型４から離反する方向と反対方向であると、仮保持部２からクリップ５が脱落するおそれがある。従って、仮保持部２による保持力を、クリップ５を成形型４から離反する方向と交差する方向とすることで、収容部１１を成形型４から離反させる際にクリップ５だけを成形型４に残存させ易い。 Further, in this embodiment, the urging means composed of the coil spring 18 generates an urging force in a direction intersecting the direction in which the clip 5 is separated from the molding die 4. This urging force becomes the holding force of the temporary holding portion 2 that temporarily holds the clip 5. If the clip holding force is in the same direction as the direction in which the clip 5 is separated from the molding die 4, it becomes difficult to remove the clip 5 from the temporary holding portion 2 when the accommodating portion 11 is separated from the molding die 4. On the contrary, if the clip holding force is in the direction opposite to the direction in which the clip 5 is separated from the molding die 4, the clip 5 may fall off from the temporary holding portion 2. Therefore, by setting the holding force of the temporary holding portion 2 in the direction intersecting the direction in which the clip 5 separates from the molding die 4, only the clip 5 becomes the molding die 4 when the accommodating portion 11 is separated from the molding die 4. Easy to remain.

また、クリップ収容状態におけるボール１９と基底部９との接触状態は、例えば図９に示すように、ボール（球）１９の中心より収容部１１の連結基底部１２側の球面部が基底部９に接触するのが望ましい。つまり、クリップ５の基底部９は、ボール１９の中心より連結基底部１２側の球面部と連結基底部１２とで挟持される。この状態は、対向するボール１９間に基底部９を押し込むときのボール１９のケース１７内への最大押し込み状態から少しボール１９がケース１７外に戻っている。例えば、基底部９を仮保持部２から抜去する方向と、ボール１９と基底部９との接触位置における接線とがなす角度をボールと基底部９との接触角と定義する。クリップ収容状態でクリップ５の基底部９がボール１９の中心より連結基底部１２側の球面部と連結基底部１２とで挟持されるようにすることで、ボール１９と基底部９との接触角によって、対向するボール１９間から基底部９が簡単に抜け落ちてしまわないようにすることができる。その一方で、仮保持部２からクリップ５を抜去する力が作用すると、基底部９が連結基底部１２から離間するにつれてボール１９と基底部９との接触角が次第に小さくなるので、仮保持部２から基底部９を容易に抜去することができる。 Further, in the contact state between the ball 19 and the base portion 9 in the clip accommodating state, for example, as shown in FIG. 9, the spherical surface portion on the connecting base portion 12 side of the accommodating portion 11 from the center of the ball (ball) 19 is the base portion 9. It is desirable to contact with. That is, the base portion 9 of the clip 5 is sandwiched between the spherical surface portion on the connecting base portion 12 side from the center of the ball 19 and the connecting base portion 12. In this state, the ball 19 is slightly returned to the outside of the case 17 from the maximum pushing state of the ball 19 into the case 17 when the base portion 9 is pushed between the opposing balls 19. For example, the angle formed by the direction in which the base portion 9 is removed from the temporary holding portion 2 and the tangent line at the contact position between the ball 19 and the base portion 9 is defined as the contact angle between the ball and the base portion 9. The contact angle between the ball 19 and the base portion 9 is formed by sandwiching the base portion 9 of the clip 5 between the spherical surface portion on the connecting base portion 12 side and the connecting base portion 12 from the center of the ball 19 in the clip housing state. Therefore, it is possible to prevent the base portion 9 from easily falling out from between the opposing balls 19. On the other hand, when a force for pulling out the clip 5 from the temporary holding portion 2 acts, the contact angle between the ball 19 and the base portion 9 gradually decreases as the base portion 9 separates from the connecting base portion 12, so that the temporary holding portion The base portion 9 can be easily removed from 2.

一方、対向するボール１９間に基底部９を押し込むときの最大押し込み状態からクリップ収容状態におけるボール１９の戻り量が大きいと、コイルスプリング１８が自由長に近づくことになるので、その状態から、ボール１９を基底部９の抜去位置まで押し込む際（＝最大押し込み状態）のコイルスプリング１８の変位が大きくなる。コイルスプリング１８の変位が大きくなると、その分だけ、仮保持部２からクリップ５を抜去するのに必要な力が大きくなる。つまり、成形型４から収容部１１を離反させた際、収容部１１内にクリップ５が残存しやすくなる。 On the other hand, if the return amount of the ball 19 in the clip accommodating state is large from the maximum pushed state when the base portion 9 is pushed between the opposing balls 19, the coil spring 18 approaches the free length. When the 19 is pushed to the removed position of the base portion 9 (= maximum pushed state), the displacement of the coil spring 18 becomes large. As the displacement of the coil spring 18 increases, the force required to remove the clip 5 from the temporary holding portion 2 increases accordingly. That is, when the accommodating portion 11 is separated from the molding die 4, the clip 5 tends to remain in the accommodating portion 11.

このようなクリップ収容状態における基底部９とボール１９の位置関係は、ボールプランジャ１６と収容部１１の連結基底部１２との位置関係で決定される。この実施の形態では、クリップ収容状態でボール１９の中心より連結基底部１２側の球面部が基底部９に接触するように連結基底部１２及びボールプランジャ１６を配置する。同様に、連結基底部１２及びボールプランジャ１６の配置位置を調整して、最大押し込み状態からのボール１９の戻り量が大きくなりすぎないようにする。 The positional relationship between the base portion 9 and the ball 19 in such a clip accommodating state is determined by the positional relationship between the ball plunger 16 and the connecting base portion 12 of the accommodating portion 11. In this embodiment, the connecting base portion 12 and the ball plunger 16 are arranged so that the spherical surface portion on the connecting base portion 12 side from the center of the ball 19 contacts the base portion 9 in the clip housed state. Similarly, the arrangement positions of the connecting base portion 12 and the ball plunger 16 are adjusted so that the return amount of the ball 19 from the maximum pushed state does not become too large.

このように、この実施の形態の部品取付冶具では、取っ手１を把持して冶具基体２１を成形型４に押し付け、夫々の部品仮保持部材３に仮保持されているクリップ５の係止部６が幅狭部８に係止する。その状態から、治具基体２１を成形型４から離間し、部品仮保持部材３の収容部１１を成形型４から離反させると、係止部６が幅狭部８に係止した状態でクリップ５が成形型４に残存する。これによりクリップ５の成形型４への取付作業が完了する。そのため、従来のように、発泡樹脂成形品の脱型後に部品設置用治具を除去する必要がない。 As described above, in the component mounting jig of this embodiment, the handle 1 is gripped and the jig base 21 is pressed against the molding die 4, and the locking portion 6 of the clip 5 temporarily held by each of the component temporary holding members 3 is temporarily held. Locks to the narrow portion 8. From that state, when the jig base 21 is separated from the molding die 4 and the accommodating portion 11 of the component temporary holding member 3 is separated from the molding die 4, the locking portion 6 is locked to the narrow portion 8 and clipped. 5 remains in the molding die 4. This completes the work of attaching the clip 5 to the molding die 4. Therefore, unlike the conventional case, it is not necessary to remove the jig for installing parts after removing the mold of the foamed resin molded product.

例えば、同一ラインに複数種類の発泡樹脂成形品用の成形型４が存在する場合、夫々の種類の成形型４に応じて、クリップ取付位置に部品仮保持部材３が取付けられた部品取付治具を用意する。そして、夫々の部品取付治具の部品仮保持部材３の収容部１１にクリップ５を規定姿勢で収容し、夫々の部品取付治具を対応する成形型４に押し付けてクリップ５を成形型４に取付ける。このようにすれば、ライン速度を低下することなく、成形型４へのクリップ５の誤取付を回避することが可能となる。これは、発泡樹脂成形品へのクリップ５の誤組付けを回避することと同じである。また、部品仮保持部材３の収容部１１にクリップ５を規定姿勢で収容するだけでクリップ５が仮保持されるため、クリップ5の脱着が容易で作業性に優れると共に、クリップ５の姿勢を間違えることもない。 For example, when there are a plurality of types of foam resin molded products 4 in the same line, a component mounting jig in which the component temporary holding member 3 is mounted at the clip mounting position according to each type of molding mold 4. Prepare. Then, the clip 5 is accommodated in the accommodating portion 11 of the component temporary holding member 3 of each component mounting jig in a predetermined posture, and each component mounting jig is pressed against the corresponding molding die 4 to press the clip 5 into the forming die 4. Install. By doing so, it is possible to avoid erroneous attachment of the clip 5 to the molding die 4 without reducing the line speed. This is the same as avoiding erroneous assembly of the clip 5 to the foamed resin molded product. Further, since the clip 5 is temporarily held by simply accommodating the clip 5 in the accommodating portion 11 of the temporary component holding member 3 in a predetermined posture, the clip 5 can be easily attached and detached, which is excellent in workability and the posture of the clip 5 is mistaken. There is no such thing.

また、この実施の形態の部品取付冶具では、前述のように、部品仮保持部材３の壁部１３に設けられた円穴１５にボールプランジャ１６のケース１７を圧入している。両者の圧入寸法は、円穴１５からボールプランジャ１６が簡単に抜けない数値に設定されている。しかしながら、例えば、長期の使用、又は多数回に亘る繰り返し部品装着作業、或いは設計寸法の誤差の累積によって、ボールプランジャ１６が円穴１５から抜けるのを防止するために、この実施の形態では、例えば図５や図９に二点鎖線で示すように、冶具基体２１の対向面２１ａのうち、部品仮保持部材３の取付箇所に２個一対の直方体形状の凸部２２を冶具基体２１と一体に形成した。この凸部２２は、部品仮保持部材３のボールプランジャ１６が抜け方向に移動するのを規制するためのものであり、冶具基体２１に部品仮保持部材３が取付けられた状態で、対向配置されるボールプランジャ１６の間に突出し、その結果、各ボールプランジャ１６の圧入方向と反対方向でボールプランジャ１６に対向する。より具体的には、この凸部２２は、ボールプランジャ１６のボール１９の動作を妨げないように、連結基底部１２側のフランジ部１７ａの直近で対向する。これにより、ボールプランジャ１６が脱落しようとしてもボールプランジャ１６のフランジ部１７ａが凸部２２の隅角部に当接してボールプランジャ１６の移動が規制され、これによりボールプランジャ１６が円穴１５から抜けるのを防止することが可能となる。 Further, in the component mounting jig of this embodiment, as described above, the case 17 of the ball plunger 16 is press-fitted into the circular hole 15 provided in the wall portion 13 of the temporary component holding member 3. The press-fitting dimensions of both are set to a value at which the ball plunger 16 cannot be easily removed from the circular hole 15. However, in this embodiment, for example, in order to prevent the ball plunger 16 from coming out of the circular hole 15 due to, for example, long-term use, repeated component mounting work over a large number of times, or accumulation of design dimensional errors, for example, As shown by the alternate long and short dash line in FIGS. 5 and 9, two pairs of rectangular parallelepiped convex portions 22 are integrally formed with the jig base 21 at the attachment points of the component temporary holding member 3 in the facing surface 21a of the jig base 21. Formed. The convex portion 22 is for restricting the movement of the ball plunger 16 of the component temporary holding member 3 in the detaching direction, and is arranged so as to face each other with the component temporary holding member 3 attached to the jig base 21. It protrudes between the ball plungers 16 and, as a result, faces the ball plunger 16 in a direction opposite to the press-fitting direction of each ball plunger 16. More specifically, the convex portion 22 faces the flange portion 17a on the connecting base portion 12 side in the immediate vicinity so as not to interfere with the operation of the ball 19 of the ball plunger 16. As a result, even if the ball plunger 16 is about to fall off, the flange portion 17a of the ball plunger 16 comes into contact with the corner portion of the convex portion 22 and the movement of the ball plunger 16 is restricted, whereby the ball plunger 16 comes out of the circular hole 15. It becomes possible to prevent.

また、この実施の形態の部品取付冶具では、図１０に示すように、取っ手並び方向両側の全ての部品仮保持部材３、即ちクリップ５の仮保持位置よりも取っ手並び方向内側に取っ手１を配置している。この実施の形態のように、２個一対の取っ手１の夫々を両手の夫々で把持し、２以上のクリップ５を部品装着位置であるリブ状突起部７の幅狭部８に押し付けるようにして取付ける場合、図１１に示すように、取っ手並び方向外側のクリップ５（部品仮保持部材３）の仮保持位置よりも取っ手並び方向外側に取っ手１が配置されていると、リブ状突起部７（幅狭部８）とクリップ５の当接箇所を支点、取っ手１の取付箇所を力点として冶具基体２１が撓んでしまう。取っ手１が取っ手並び方向外側に取付けられるほど、冶具基体２１の撓み範囲（変形範囲）が大きくなり、それだけ、特に冶具基体２１の取っ手並び方向中央部における撓み量が大きくなる。このように冶具基体２１が撓み量が大きくなると、部品仮保持部材３も、それに仮保持されているクリップ５も姿勢が変化してしまい、クリップ５をリブ状突起部７（幅狭部８）に対して適正な姿勢（規定姿勢）で取付けることができなくなるおそれがある。そのため、この実施の形態では、取っ手並び方向両外側の部品仮保持部材３、即ちクリップ５の仮保持位置よりも取っ手並び方向内側の位置に取っ手１を配置し、これにより部品取付冶具の成形型４への押し付け時の冶具基体２１の撓み量を低減するようにしている。 Further, in the component mounting jig of this embodiment, as shown in FIG. 10, all the component temporary holding members 3 on both sides in the handle alignment direction, that is, the handles 1 are arranged inside the handle alignment direction from the temporary holding position of the clip 5. doing. As in this embodiment, the two pairs of handles 1 are gripped by both hands, and the two or more clips 5 are pressed against the narrow portion 8 of the rib-shaped protrusion 7 which is the component mounting position. When mounting, as shown in FIG. 11, when the handle 1 is arranged outside the handle alignment direction from the temporary holding position of the clip 5 (part temporary holding member 3) outside the handle alignment direction, the rib-shaped protrusion 7 ( The jig base 21 bends with the contact point between the narrow portion 8) and the clip 5 as a fulcrum and the attachment point of the handle 1 as a force point. The more the handle 1 is attached to the outside in the handle alignment direction, the larger the bending range (deformation range) of the jig base 21, and the more the bending amount of the jig base 21 in the center of the handle alignment direction becomes larger. When the amount of bending of the jig base 21 becomes large in this way, the postures of the component temporary holding member 3 and the clip 5 temporarily held by the component temporary holding member 3 change, and the clip 5 is formed into a rib-shaped protrusion 7 (narrow portion 8). There is a risk that it will not be possible to install in the proper posture (specified posture). Therefore, in this embodiment, the handle 1 is arranged at a position inside the handle alignment direction of the component temporary holding member 3 on both outer sides of the handle alignment direction, that is, the temporary holding position of the clip 5, thereby forming a molding die for the component mounting jig. The amount of bending of the jig base 21 at the time of pressing against 4 is reduced.

図１２、図１３は、この実施の形態の部品取付冶具を簡略化した平面図である（貫通開口部１４は図示を省略している）。前述のように取っ手１を両手で把持して部品取付冶具を成形型４に押し付ける場合、冶具基体２１の撓み量を低減する必須条件は、例えば図１２に示すように、取っ手並び方向の最も外側に位置する部品仮保持部材３に仮保持されるクリップ５の位置よりも取っ手並び方向の内側に取っ手１を配置することである。しかしながら、例えば取っ手並び方向の何れか一方の外側又は双方の外側の夫々で、例えば取っ手並び方向と交差する方向に２以上のクリップ５が仮保持される場合に、取っ手並び方向の最も外側のクリップ５の仮保持位置より取っ手１が取っ手並び方向内側に配置されても、例えば外側から２番目のクリップ５の仮保持位置より取っ手１が取っ手並び方向外側に配置されると、その外側から２番目のクリップ５の部分で冶具基体２１の撓み量が大きくなるおそれがある。 12 and 13 are plan views in which the component mounting jig of this embodiment is simplified (the through opening 14 is not shown). When the handle 1 is gripped with both hands and the component mounting jig is pressed against the mold 4 as described above, the essential condition for reducing the amount of bending of the jig base 21 is, for example, the outermost part in the handle alignment direction, as shown in FIG. The handle 1 is arranged inside the handle arrangement direction from the position of the clip 5 temporarily held by the component temporary holding member 3 located at. However, for example, when two or more clips 5 are temporarily held on the outside of either one of the handle alignment directions or on the outside of both, for example, in the direction intersecting the handle alignment direction, the outermost clip in the handle alignment direction is temporarily held. Even if the handle 1 is arranged inside the handle alignment direction from the temporary holding position of 5, for example, if the handle 1 is arranged outside the handle alignment direction from the temporary holding position of the second clip 5 from the outside, it is the second from the outside. There is a possibility that the amount of bending of the jig base 21 will be large at the portion of the clip 5.

そこで、そのような場合、つまり取っ手並び方向の何れか一方の外側位置又は双方の外側位置で夫々複数のクリップ５が仮保持される場合にあっては、図１３に示すように、取っ手並び方向の何れか一方の外側又は双方の外側で夫々最も外側に位置する二つのクリップ５（部品仮保持部材３）の仮保持位置を結んだ、取っ手並び方向と交差する方向の線分よりも取っ手並び方向の内側に取っ手１を配置することで冶具基体２１の撓み量を低減することができる。なお、何れの場合にあっても、例えば冶具基体２の逆向きの撓みを回避するためにも、２個一対の取っ手１を取っ手並び方向の極端な内側に配置することは回避すべきである。 Therefore, in such a case, that is, when a plurality of clips 5 are temporarily held at either one outer position or both outer positions in the handle arrangement direction, as shown in FIG. 13, the handle arrangement direction. Handle alignment rather than the line segment in the direction intersecting the handle alignment direction connecting the temporary holding positions of the two clips 5 (part temporary holding members 3) located on the outer side of either one or the outermost sides of both sides. By arranging the handle 1 inside the direction, the amount of bending of the jig base 21 can be reduced. In any case, for example, in order to avoid the reverse bending of the jig base 2, it is necessary to avoid arranging the pair of two handles 1 extremely inside the handle alignment direction. ..

また、この実施の形態では、前述したように、冶具基体２１の複数個所において、反対面２１ｂから対向面２１ａまで貫通する貫通開口部１４を形成した。この貫通開口部１４は、成形型４を目視するためのものである。特に、この実施の形態では、リブ状突起部７の全ての幅狭部８にクリップ５を規定姿勢で取付けできるように、貫通開口部１４を通じてリブ状突起部７が目視できる箇所に貫通開口部１４を設けている。具体的に、これらの貫通開口部１４は、取っ手１の取付箇所、及び部品仮保持部材３の取付箇所を除いて、冶具基体２１の幅方向中央部、つまりリブ状突起部７の対向位置に開設している。この実施の形態のように、１つの部品取付冶具で、リブ状突起部７の全ての幅狭部８にクリップ５を取付けようとする場合、冶具基体２１の対向面２１ａは全ての幅狭部８に対向する大きさが必要である。つまり、クリップ５の取付作業時、少なくとも全ての幅狭部８に該当するリブ状突起部７は冶具基体２１に覆われて目視することができない。そのため、作業者は、部品取付冶具、即ち冶具基体２１がリブ状突起部７に対して適正な位置や姿勢にあるかどうかを認識しにくい。そこで、この実施の形態では、冶具基体２１の反対面２１ｂから対向面２１ａまで貫通する貫通開口部１４を設け、この貫通開口部１４を通じて成形型、特にリブ状突起を目視できるようにすることで、冶具基体２１がリブ状突起部７、即ち成形型４に対して適正な位置や姿勢にあるかどうかを認識できるようにした。 Further, in this embodiment, as described above, through openings 14 penetrating from the opposite surface 21b to the facing surface 21a are formed at a plurality of locations of the jig substrate 21. The through opening 14 is for visually recognizing the molding die 4. In particular, in this embodiment, a through opening is provided at a position where the rib-shaped protrusion 7 can be visually recognized through the through opening 14 so that the clip 5 can be attached to all the narrow portions 8 of the rib-shaped protrusion 7 in a specified posture. 14 is provided. Specifically, these through openings 14 are located at the center of the jig base 21 in the width direction, that is, at positions facing the rib-shaped protrusions 7, except for the attachment points of the handle 1 and the attachment points of the temporary component holding member 3. It is open. When the clip 5 is to be attached to all the narrow portions 8 of the rib-shaped protrusion 7 with one component mounting jig as in this embodiment, the facing surface 21a of the jig base 21 is all the narrow portions. A size facing 8 is required. That is, at the time of attaching the clip 5, at least all the rib-shaped protrusions 7 corresponding to the narrow portions 8 are covered with the jig base 21 and cannot be visually recognized. Therefore, it is difficult for the operator to recognize whether or not the component mounting jig, that is, the jig base 21, is in an appropriate position and posture with respect to the rib-shaped protrusion 7. Therefore, in this embodiment, a through opening 14 penetrating from the opposite surface 21b to the facing surface 21a of the jig base 21 is provided, and the molding die, particularly the rib-shaped protrusion is visible through the through opening 14. , It is possible to recognize whether or not the jig base 21 is in an appropriate position and posture with respect to the rib-shaped protrusion 7, that is, the molding die 4.

このように、この実施の形態の部品取付冶具では、部品仮保持部材３によってクリップ５が仮保持されている状態でクリップ５の係止部６を成形型４のリブ状突起部７の幅狭部８に係止すると、その係止力は部品仮保持部材３によるクリップ５の保持力よりも大きいため、その状態で冶具基体２１を成形型４から離反させると、クリップ５は部品仮保持部材３から抜去されて成形型４のリブ状突起部７の幅狭部８に残存する。これにより、発泡樹脂成形品の脱型後に部品設置用治具を除去することなく、クリップ５の発泡樹脂成形品への装着を簡単かつ迅速に完了することができる。 As described above, in the component mounting jig of this embodiment, the locking portion 6 of the clip 5 is narrowed by the rib-shaped protrusion 7 of the molding die 4 while the clip 5 is temporarily held by the component temporary holding member 3. When locked to the portion 8, the locking force thereof is larger than the holding force of the clip 5 by the component temporary holding member 3. Therefore, when the jig base 21 is separated from the molding die 4 in that state, the clip 5 becomes the component temporary holding member. It is removed from 3 and remains in the narrow portion 8 of the rib-shaped protrusion 7 of the molding die 4. As a result, the attachment of the clip 5 to the foamed resin molded product can be completed easily and quickly without removing the component installation jig after the foamed resin molded product is demolded.

その際、取っ手１を把持して冶具基体２１を成形型４に押し付けても、取っ手並び方向の最も外側に位置するクリップ５の仮保持位置よりも取っ手１が取っ手並び方向内側に配置されているために、取っ手並び方向外側に取っ手１が配置されている場合に比べて冶具基体２１の撓み（変形）量が低減され、クリップ５を規定姿勢でリブ状突起部７の幅狭部８に取付けることが可能となる。 At that time, even if the handle 1 is gripped and the jig base 21 is pressed against the molding die 4, the handle 1 is arranged inside the handle alignment direction with respect to the temporary holding position of the clip 5 located on the outermost side in the handle alignment direction. Therefore, the amount of bending (deformation) of the jig base 21 is reduced as compared with the case where the handles 1 are arranged outside the handle alignment direction, and the clip 5 is attached to the narrow portion 8 of the rib-shaped protrusion 7 in a predetermined posture. It becomes possible.

また、取っ手並び方向の何れか一方の外側又は双方の夫々の外側の最も外側に位置する二つのクリップ５の仮保持位置を結んだ線分よりも取っ手並び方向内側に取っ手１を配置する。これにより、取っ手並び方向の何れか一方の外側位置又は双方の夫々の外側位置でクリップ５が複数仮保持される場合であっても、取っ手１を把持して冶具基体２１を成形型４に押し付ける際、冶具基体２１の撓み（変形）量が確実に低減され、クリップ５を規定姿勢で確実にリブ状突起部７の幅狭部８に取付けることが可能となる。 Further, the handle 1 is arranged inside the handle alignment direction with respect to the line segment connecting the temporary holding positions of the two clips 5 located on the outer side of either one of the handle alignment directions or the outermost side of each of the two clips 5. As a result, even when a plurality of clips 5 are temporarily held at one of the outer positions in the handle alignment direction or at the outer positions of both, the handle 1 is grasped and the jig base 21 is pressed against the molding die 4. At that time, the amount of bending (deformation) of the jig base 21 is surely reduced, and the clip 5 can be surely attached to the narrow portion 8 of the rib-shaped protrusion 7 in the specified posture.

また、成形型４を目視可能な貫通開口部１４を冶具基体２１の反対面２１ｂから対向面２１ａまで貫通して設けたことにより、貫通開口部１４を通じて成形型４を目視して成形型４に対する冶具基体２１の位置や姿勢を適正な状態とすることができるので、クリップ５を成形型４のリブ状突起部７の適正な幅狭部８に適正に取付けることが可能となる。 Further, by providing the molding die 4 with a visible through opening 14 penetrating from the opposite surface 21b of the jig base 21 to the facing surface 21a, the molding die 4 is visually observed through the through opening 14 with respect to the molding die 4. Since the position and posture of the jig base 21 can be set to an appropriate state, the clip 5 can be appropriately attached to the appropriate narrow portion 8 of the rib-shaped protrusion 7 of the molding die 4.

また、部品仮保持部材３の収容部１１内にクリップ５を規定姿勢で収容すると、ボールプランジャ１６によって挟まれるようにしてクリップ５が仮保持されるので、簡単な動作で着脱が可能であり、作業性に優れると共に、クリップ５の係止部６を成形型４のリブ状突起部７の幅狭部８に装着する際、その係止作業が妨げられることもない。 Further, when the clip 5 is housed in the housing portion 11 of the component temporary holding member 3 in a predetermined posture, the clip 5 is temporarily held so as to be sandwiched by the ball plunger 16, so that the clip 5 can be attached and detached with a simple operation. In addition to being excellent in workability, when the locking portion 6 of the clip 5 is attached to the narrow portion 8 of the rib-shaped protrusion 7 of the molding die 4, the locking work is not hindered.

また、部品仮保持部材３が取付けられた状態で、対向配置されるボールプランジャ１６間に突出し、各ボールプランジャ１６の圧入方向と反対方向でボールプランジャ１６に対向する凸部２２を冶具基体２１の対向面２１ａに設けたことにより、この部品仮保持部材３が取付けられた冶具基体２１を用いて部品取付作業を繰り返しても、ボールプランジャ１６が圧入方向と反対方向に抜けてしまうのを冶具基体２１の凸部２２で防止することができる。 Further, with the component temporary holding member 3 attached, the convex portion 22 that protrudes between the ball plungers 16 that are arranged to face each other and faces the ball plunger 16 in the direction opposite to the press-fitting direction of each ball plunger 16 is formed on the jig base 21. By providing the ball plunger 16 on the facing surface 21a, the ball plunger 16 is prevented from coming off in the direction opposite to the press-fitting direction even if the component mounting work is repeated using the jig substrate 21 to which the component temporary holding member 3 is attached. It can be prevented by the convex portion 22 of 21.

なお、前述した実施の形態では、挟持手段としてボールプランジャ１６を用いているが、ボールプランジャ１６以外のものでも挟持手段として用いることができる。また、ボールプランジャ１６と同等の構成を収容部１１の壁部１３内に構築することも可能である。そのような場合であっても、前述と同様の手法によって挟持手段による仮保持部の保持力を設定すればよい。 In the above-described embodiment, the ball plunger 16 is used as the pinching means, but a device other than the ball plunger 16 can also be used as the pinching means. Further, it is also possible to construct a configuration equivalent to that of the ball plunger 16 in the wall portion 13 of the accommodating portion 11. Even in such a case, the holding force of the temporary holding portion by the holding means may be set by the same method as described above.

また、前述した実施形態では、仮保持部であるボール１９がクリップ５を挟んで正対するように配置しているが、仮保持部はクリップ５、つまり部品を挟んで対向すればよいのであって、必ずしも正対する必要はない。 Further, in the above-described embodiment, the balls 19 which are temporary holding portions are arranged so as to face each other with the clip 5 sandwiched between them. However, the temporary holding portions may face each other with the clip 5, that is, a component sandwiched between them. , It is not always necessary to face it.

また、収容部１１の形状は、２本の平行な梁状壁部１３に限定されるものではなく、クリップ５が当接する連結基底部１２と、その連結基底部１２と交差する方向に突設されて互いに対向する２以上の壁部１３とを有するものであればよい。 Further, the shape of the accommodating portion 11 is not limited to the two parallel beam-shaped wall portions 13, but is projected in a direction intersecting the connecting base portion 12 with which the clip 5 abuts and the connecting base portion 12. It suffices as long as it has two or more wall portions 13 facing each other.

また、発泡樹脂成形品用の成形型４に取付ける部品は、クリップ５以外の部品であってもよい。 Further, the component to be attached to the molding die 4 for the foamed resin molded product may be a component other than the clip 5.

本発明が上記していない様々な実施の形態等を含むことは勿論である。従って、本発明の技術的範囲は上記の説明から妥当とされる特許請求の範囲に記載された発明特定事項によってのみ定められるものである。 It goes without saying that the present invention includes various embodiments not described above.
