Abstract

<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a molded structure which prevents flashes from forming from the molded body and a molding die structure for the same. <P>SOLUTION: A moveable die 72 is capable of moving with respect to a stationary die 71. A cavity 73 having an opening 74 down below is formed between the both dies when the dies are clumped. A trim board 2 is disposed so as to close the opening 74 from underneath. A bracket 3 is agglutinated onto the trim board 2 by injecting a molding material MZ into the cavity 73. Flashes do not run off on the trim board 2 from the bracket 3 because a convex part 71c and a protrusion 72c projected from an under face 71d, 72d of the stationary die 71 and the moveable die 72 respectively bite into the trim board 2. After molding, the protrusion 72c can be released from the bracket 3 by retreating the moveable die 72 aslant to the under face 72d. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

本発明は、基体上に成形体を接合して形成した成形構造体の製造方法と、そのための成形型構造に関する。   The present invention relates to a method for manufacturing a molded structure formed by bonding a molded body on a substrate, and a mold structure for the manufacturing method.

従来技術として、一側が開口し、その内部に成形体と同形状のキャビティを形成した１つの成形型に、このキャビティの開口を閉塞するように基板を配置するとともに、キャビティ内に合成樹脂材料を射出して成形体を形成しながら、基板に接合させるインジェクション成形による方法があった（例えば、特許文献１参照）。これによれば、キャビティ内に行き渡るように、成形材料を高圧で射出するため、キャビティを閉塞している基板と成形型との間から、成形材料が漏れ出ることがあり、これが、成形後に成形品のバリとなって基板上に残ってしまうことがあった。基板上に付着した成形品のバリは、見栄えの点において、その要求される品質を満たさないばかりか、基板上に広がったバリが、熱収縮によって基板に対して応力を発生させ、この応力より基板の剛性が小さい場合は、基板にそりが生ずることもあった。   As a conventional technique, a substrate is placed in one mold having an opening on one side and a cavity having the same shape as that of the molded body in the mold so as to close the opening of the cavity, and a synthetic resin material is placed in the cavity. There has been a method by injection molding in which a molded body is formed by injection and bonded to a substrate (see, for example, Patent Document 1). According to this, since the molding material is injected at a high pressure so as to reach the inside of the cavity, the molding material may leak from between the substrate closing the cavity and the molding die, which is molded after molding. In some cases, it became a product burr and remained on the substrate. The burrs of the molded product attached on the substrate do not meet the required quality in terms of appearance, but the burrs spread on the substrate generate stress on the substrate due to thermal shrinkage, and this stress When the rigidity of the substrate is small, the substrate may be warped.

また、基板のように予め形成されたものの表面に、バリを付着させないようにするために、一側の成形型の開口の周囲に当接するように突起を設けて、成形時に、この突起を他側の成形型に形成されたシール材に当接させることで、キャビティからの成形材料の漏れを防止することに関する従来技術があった（例えば、特許文献２参照）。しかしながら、上述した突起を、基板に成形体を接合して成形する場合にそのまま適用すれば、その型構造上、成形工程において、新たな課題が発生することがあった。特に、成形後に、成形型を基板表面に沿って型抜きせざるを得ないような場合（例えば、アンダーカット形状）、上述した突起が基板と当接して、型抜きができなくなることがあり、移動コア等を用いて型抜きしなければならないことがあった。
特開２００２−３５５８４８公報（第６図） 実開平７−２３５１５号公報（第１図） In addition, in order to prevent burrs from adhering to the surface of a previously formed substrate such as a substrate, a protrusion is provided so as to contact the periphery of the opening of the mold on one side. There has been a conventional technique relating to preventing leakage of a molding material from a cavity by contacting a sealing material formed on a side mold (see, for example, Patent Document 2). However, if the above-described protrusion is applied as it is when the molded body is bonded to the substrate and molded, a new problem may occur in the molding process due to its mold structure. In particular, after molding, when the mold must be punched along the surface of the substrate (for example, undercut shape), the above-described protrusions may come into contact with the substrate and die cutting may not be possible. In some cases, it was necessary to perform die cutting using a moving core or the like.

本発明の実施形態を図１乃至図１１によって説明する。本実施形態による成形構造体は、車両ドアを構成するドアトリム１である。図１に示すように、ドアトリム１は本発明の基体に該当するトリムボード２上に、本発明の成形体に該当するブラケット３が固着されることにより形成されている。尚、本来、トリムボード２の一面には複数のブラケット３が取り付けられているが、図１においては、トリムボード２を破断させて、一つのブラケット３の取付部位のみを示している。   An embodiment of the present invention will be described with reference to FIGS. The molded structure according to the present embodiment is a door trim 1 that constitutes a vehicle door. As shown in FIG. 1, the door trim 1 is formed by fixing a bracket 3 corresponding to the molded body of the present invention on a trim board 2 corresponding to the base body of the present invention. Note that a plurality of brackets 3 are originally attached to one surface of the trim board 2, but in FIG. 1, only the attachment portion of one bracket 3 is shown by breaking the trim board 2.

平板状のトリムボード２は、木材などを解織して得た木質繊維、あるいはケナフ等の靭皮植物繊維に熱可塑性樹脂材料であるポリプロピレンを含浸させた基材２１と、基材２１上に合成皮革、天然皮革あるいは繊維によって形成された表皮２２が被覆されることにより構成されている。本実施形態において、ポリプロピレンは植物繊維を繋ぐバインダとしての役割を果たしているが、基材２１をポリプロピレンあるいは、その他の熱可塑性樹脂材料のみにて形成する、もしくはポリエチレンテレフタレート、ポリ乳酸樹脂等のポリプロピレン以外の熱可塑性樹脂材料と植物繊維との混合物にて形成してもよい。   The flat trim board 2 includes a base material 21 obtained by impregnating a wood fiber obtained by weaving wood or the like, or a bast plant fiber such as kenaf with polypropylene, which is a thermoplastic resin material, and a base material 21. It is constituted by covering a skin 22 formed of synthetic leather, natural leather or fiber. In this embodiment, polypropylene plays a role as a binder for connecting plant fibers, but the base material 21 is formed only of polypropylene or other thermoplastic resin material, or other than polypropylene such as polyethylene terephthalate and polylactic acid resin. You may form with the mixture of the thermoplastic resin material of this, and a vegetable fiber.

ブラケット３は基材２１に含浸している熱可塑性樹脂材料と同質の材料（ポリプロピレン、ポリエチレンテレフタレート、ポリ乳酸樹脂等）によって一体に形成され、図１に示すように、外周面が傾斜した筒体をおよそ半割りしたような形状をしており、その大径側がトリムボード２の基材２１に接合されている。また、ブラケット３の先端部には、その先端面が平坦な略半円状の立壁３１が設けられ、その端部には真円状の切欠３２が開口している。立壁３１の後面３１ａは、後述する移動型７２の斜め方向への型抜きが可能なように、斜面に形成されており、このため、立壁３１は端部に向けて、徐々に板厚が薄くなっている（図１０示）。一方、ブラケット３のトリムボード２への接合部３３は、所定の幅を有しながら半円状に延びており、これによって、ブラケット３はトリムボード２の基材２１側に固着されている。ブラケット３の切欠３２に、図示しないクリップを固定し、このクリップを車両ドアの図示しないインナパネルの係止部に係合させることにより、ドアトリム１は車両ドアに取り付けられる。   The bracket 3 is integrally formed of the same material (polypropylene, polyethylene terephthalate, polylactic acid resin, etc.) as the thermoplastic resin material impregnated in the substrate 21, and as shown in FIG. The large-diameter side is joined to the base material 21 of the trim board 2. Further, a substantially semicircular standing wall 31 having a flat front end surface is provided at the front end of the bracket 3, and a perfect circular cutout 32 is opened at the end. The rear surface 31a of the standing wall 31 is formed on an inclined surface so that the movable mold 72 described later can be cut in an oblique direction. For this reason, the standing wall 31 gradually decreases in thickness toward the end. (Shown in FIG. 10). On the other hand, the joint portion 33 of the bracket 3 to the trim board 2 extends in a semicircular shape while having a predetermined width, whereby the bracket 3 is fixed to the base 21 side of the trim board 2. The door trim 1 is attached to the vehicle door by fixing a clip (not shown) to the notch 32 of the bracket 3 and engaging the clip with an engaging portion of an inner panel (not shown) of the vehicle door.

次に、トリムボード２にブラケット３を成形する成形装置４について、図２に基づいて説明する。説明中、図２において右方を移動型７２の前方とする。本実施形態による成形装置４は、成形材料導入装置５、成形型移動装置６、成形型構造７、基体搬送装置８を備えている射出成形装置である。成形型移動装置６に取り付けられた固定型７１は、支持体６１の上端部６１ａに形成された収容孔６１ｂ内に、下方に垂下するように、溶接、ボルト締め等で固定されている。支持体６１は、おおよそ逆Ｌ字状をしており、その下端部６１ｃが基体搬送装置８の上部に固定されるとともに、その側端部６１ｄには成形型移動装置６の移動用アクチュエータ６２が、水平方向に対して僅かながら下方に傾斜して取り付けられている。   Next, a molding apparatus 4 for molding the bracket 3 on the trim board 2 will be described with reference to FIG. In the description, the right side in FIG. The molding apparatus 4 according to the present embodiment is an injection molding apparatus that includes a molding material introducing device 5, a molding die moving device 6, a molding die structure 7, and a substrate conveying device 8. The fixed die 71 attached to the molding die moving device 6 is fixed by welding, bolting, or the like so as to hang downward in the accommodation hole 61b formed in the upper end portion 61a of the support 61. The support 61 has an approximately inverted L shape, and its lower end portion 61c is fixed to the upper portion of the substrate transport device 8, and a movement actuator 62 of the mold moving device 6 is provided at its side end portion 61d. It is attached with a slight inclination with respect to the horizontal direction.

移動型７２は前方部に型面７２ａを有し（図５示）、これが固定型７１の型面７１ａと対向するように配置され、その閉型状態において、型面７１ａと型面７２ａとの間には、キャビティ７３が形成される（図６示）。図６に示されたように、固定型７１と移動型７２は、下方にトリムボード２が配置されていない状態において、外部に向いた開口７４を有している。固定型７１のガイド面７１ｂ、および移動型７２の上面７２ｂは、互いに係合するように、移動用アクチュエータ６２と同じ角度だけ傾斜している。   The movable mold 72 has a mold surface 72a in the front portion (shown in FIG. 5), which is disposed so as to face the mold surface 71a of the fixed mold 71. In the closed mold state, the movable mold 72 has a mold surface 71a and a mold surface 72a. A cavity 73 is formed between them (shown in FIG. 6). As shown in FIG. 6, the fixed die 71 and the movable die 72 have an opening 74 facing outward in a state where the trim board 2 is not disposed below. The guide surface 71b of the fixed die 71 and the upper surface 72b of the moving die 72 are inclined by the same angle as the moving actuator 62 so as to engage with each other.

移動型７２は、成形型移動装置６を構成するスライドシャフト６３の前端部に固着されている。スライドシャフト６３は移動用アクチュエータ６２に接続され、水平方向に対して、移動用アクチュエータ６２と同じ角度だけ傾斜している。移動用アクチュエータ６２は、電動モータによるアクチュエータ、エアシリンダ、油圧シリンダ、電磁ソレノイドアクチュエータ等のあらゆるものが使用可能であり、移動用アクチュエータ６２の作動により、スライドシャフト６３を介して、移動型７２が移動方向である前後方向に対して、僅かに固定型７１に向けて下方に傾斜した方向に往復動することができる。   The movable die 72 is fixed to the front end portion of the slide shaft 63 that constitutes the molding die moving device 6. The slide shaft 63 is connected to the moving actuator 62 and is inclined by the same angle as the moving actuator 62 with respect to the horizontal direction. The moving actuator 62 can be any of an electric motor actuator, an air cylinder, a hydraulic cylinder, an electromagnetic solenoid actuator, and the like, and the moving type 72 is moved via the slide shaft 63 by the operation of the moving actuator 62. It can reciprocate in a direction slightly inclined downward toward the fixed mold 71 with respect to the front-rear direction.

成形型移動装置６は、図示しないコントローラによって制御され、コントローラは移動型７２を前進（図５において右方へと移動）させて、図６に示された成形位置（閉型位置）まで移動させて、それ以上前方へ移動させることはない。この位置において、コントローラは、例えば、移動用アクチュエータ６２の電動モータに取り付けられたパルスエンコーダにより、その回転位置を検出し、それに基づいて移動用アクチュエータ６２を停止させる。あるいは、移動型７２の位置を検出する図示しないリミットスイッチが発生する信号に基づいて、移動用アクチュエータ６２を停止させてもよい。成形位置において、キャビティ７３の大きさは最小となり、その形状は形成されるブラケット３の形状と一致している。   The mold moving device 6 is controlled by a controller (not shown), and the controller moves the movable mold 72 forward (moves to the right in FIG. 5) and moves it to the molding position (closed mold position) shown in FIG. And no further forward. At this position, for example, the controller detects the rotational position by a pulse encoder attached to the electric motor of the moving actuator 62 and stops the moving actuator 62 based on the detected rotational position. Alternatively, the moving actuator 62 may be stopped based on a signal generated by a limit switch (not shown) that detects the position of the movable die 72. At the molding position, the size of the cavity 73 is minimized, and its shape matches the shape of the bracket 3 to be formed.

一方、成形後に移動型７２が後退して、上述した成形位置よりも固定型７１から離れた位置（開型位置）にある状態となった時（図５および図９示）、上述したパルスエンコーダによって検出された移動用アクチュエータ６２の電動モータの回転位置に基づいて、移動用アクチュエータ６２の作動を停止させる、あるいは移動型７２に取り付けられた図示しないリミットスイッチが、支持体６１の側端部６１ｄと当接して停止信号を発信し、これを受信したコントローラが移動用アクチュエータ６２の作動を停止させる。   On the other hand, when the movable die 72 moves backward after molding and is in a position (opening position) farther from the fixed die 71 than the molding position described above (shown in FIGS. 5 and 9), the pulse encoder described above. On the basis of the rotational position of the electric motor of the moving actuator 62 detected by, the operation of the moving actuator 62 is stopped, or a limit switch (not shown) attached to the moving die 72 is provided on the side end 61d of the support 61. , A stop signal is transmitted, and the controller that receives the stop signal stops the operation of the moving actuator 62.

基体搬送装置８は上述したコントローラにより制御され、支持体６１の下端部６１ｃが固定された箱体８１と、この上に取り付けられた台座８２を有している。箱体８１内には移動用アクチュエータ６２と同様の搬送用アクチュエータ８３が収容され、この搬送用アクチュエータ８３からは作動シャフト８４が上方に向けて延びており、その上端部には押圧部８５が固着されている。押圧部８５の上端面には、合成ゴムあるいは合成樹脂材料にて平板状に形成された撓み可能なクッション部８６が、接着剤等にて固定されている。   The substrate transfer device 8 is controlled by the controller described above, and has a box 81 to which the lower end portion 61c of the support 61 is fixed, and a pedestal 82 attached thereon. The box body 81 accommodates a transfer actuator 83 similar to the movement actuator 62, and an operating shaft 84 extends upward from the transfer actuator 83, and a pressing portion 85 is fixed to the upper end portion thereof. Has been. A bendable cushion portion 86 formed in a flat plate shape with synthetic rubber or synthetic resin material is fixed to the upper end surface of the pressing portion 85 with an adhesive or the like.

押圧部８５は、搬送用アクチュエータ８３の作動により作動シャフト８４を介して上昇し、クッション部８６を介してトリムボード２を持ち上げ、固定型７１および移動型７２の下端部に当接させて、キャビティ７３の開口を閉塞した状態で最上位置となる。搬送用アクチュエータ８３は、その最下位置および最上位置において、移動用アクチュエータ６２と同様に、搬送用アクチュエータ８３の図示しない電動モータの回転位置を検知して、あるいはリミットスイッチ等を使用して停止させられる。また、支持体６１の柱部６１ｅには、後述するように、トリムボード２を左右方向に搬送する際に、その位置決めのために使用される基体ガイド６６が取り付けられている。   The pressing portion 85 is lifted via the operation shaft 84 by the operation of the conveyance actuator 83, lifts the trim board 2 via the cushion portion 86, and comes into contact with the lower ends of the fixed die 71 and the movable die 72, thereby The uppermost position is reached with the opening 73 closed. The transfer actuator 83 detects the rotational position of an electric motor (not shown) of the transfer actuator 83 at the lowest position and the highest position, or stops it using a limit switch or the like. It is done. Further, as will be described later, a base body guide 66 used for positioning the trim board 2 in the left-right direction is attached to the column portion 61e of the support body 61.

成形材料導入装置５はコントローラによって制御され、支持体６１の上方に配置され、その下端部は固定型７１の上端部に挿入されている。成形材料導入装置５は、内部に導入シリンダ５２を有したシリンダボデー５１を備えており、導入シリンダ５２内には導入用アクチュエータ５３の押圧プランジャ５４が嵌合している。導入用アクチュエータ５３は、移動用アクチュエータ６２と同様のもので、これが作動することにより、押圧プランジャ５４を上下方向に移動させる。また、押圧プランジャ５４の最上位置および最下位置においては、移動用アクチュエータ６２と同様に、リミットスイッチ等を使用して導入用アクチュエータ５３が停止させられる。導入シリンダ５２には、ポリプロピレン等の合成樹脂による成形材料ＭＺを貯蔵したホッパ５５が連通しており、常時、成形材料ＭＺを供給可能にしている。   The molding material introducing device 5 is controlled by a controller and is disposed above the support 61, and the lower end portion thereof is inserted into the upper end portion of the fixed mold 71. The molding material introduction device 5 includes a cylinder body 51 having an introduction cylinder 52 therein, and a pressing plunger 54 of an introduction actuator 53 is fitted in the introduction cylinder 52. The introduction actuator 53 is the same as the movement actuator 62, and when this operates, the pressing plunger 54 is moved in the vertical direction. In addition, at the uppermost position and the lowermost position of the pressing plunger 54, similarly to the moving actuator 62, the introducing actuator 53 is stopped using a limit switch or the like. The introduction cylinder 52 communicates with a hopper 55 that stores a molding material MZ made of a synthetic resin such as polypropylene, and can always supply the molding material MZ.

シリンダボデー５１の下端部には、加熱ボデー５６が接続されており、その内部には溶融通路５７が形成されている。加熱ボデー５６の周囲には複数の電熱ヒータ５９が取り付けられ、溶融通路５７内の成形材料ＭＺが加熱されて溶融している。加熱ボデー５６の下端部は固定型７１の上端部に挿入されており、溶融通路５７の先端部に形成されたノズル５８から、溶融された成形材料ＭＺが、押圧プランジャ５４のストローク分の量をキャビティ７３内に注入可能とされている。   A heating body 56 is connected to the lower end portion of the cylinder body 51, and a melting passage 57 is formed therein. A plurality of electric heaters 59 are attached around the heating body 56, and the molding material MZ in the melting passage 57 is heated and melted. The lower end portion of the heating body 56 is inserted into the upper end portion of the fixed die 71, and the molten molding material MZ from the nozzle 58 formed at the distal end portion of the melting passage 57 has an amount corresponding to the stroke of the pressing plunger 54. Injection into the cavity 73 is possible.

次に、図３および図４に基づいて、成形型構造７を構成する固定型７１および移動型７２について詳述する。固定型７１の下端にある開口７４を取り囲む角部には、凸部７１ｃが形成されている。凸部７１ｃは、成形時にトリムボード２の表面と当接する下面７１ｄから突出しており、開口７４を取り巻くように半円状に連続している。また、凸部７１ｃは、トリムボード２と当接した時にその表面に加える面圧を高めるために、先端が細く形成されている（図４示）。   Next, based on FIG. 3 and FIG. 4, the fixed mold | type 71 and the movable mold | type 72 which comprise the shaping | molding die structure 7 are explained in full detail. A convex portion 71 c is formed at a corner portion surrounding the opening 74 at the lower end of the fixed mold 71. The convex portion 71 c protrudes from the lower surface 71 d that contacts the surface of the trim board 2 at the time of molding, and is continuous in a semicircular shape so as to surround the opening 74. Further, the convex portion 71c is formed with a thin tip in order to increase the surface pressure applied to the surface of the convex portion 71c when it contacts the trim board 2 (shown in FIG. 4).

一方、移動型７２の下端においても、開口７４を取り囲む角部に突起部７２ｃが形成されている。突起部７２ｃは、その閉型時に固定型７１の凸部７１ｃと連続するように形成され、トリムボード２の表面と当接する下面７２ｄから突出しており、凸部７１ｃと同様に、トリムボード２の表面に加える面圧を高めるために、先端が鋭角状を呈している。しかし、移動型７２の動作に影響を及ばさないように、突起部７２ｃと下面７２ｄは、緩やかな傾斜面７２ｅによって連結されている（図１１示）。   On the other hand, also at the lower end of the movable die 72, a protrusion 72 c is formed at a corner that surrounds the opening 74. The projecting portion 72c is formed so as to be continuous with the convex portion 71c of the fixed die 71 when the mold is closed, and protrudes from the lower surface 72d that comes into contact with the surface of the trim board 2, and is similar to the convex portion 71c. In order to increase the surface pressure applied to the surface, the tip has an acute angle. However, the projection 72c and the lower surface 72d are connected by a gentle inclined surface 72e so as not to affect the operation of the movable die 72 (shown in FIG. 11).

次に、成形装置４を使用したブラケット３の、トリムボード２への接合方法について、図５乃至図１１に基づいて説明する。最初に、図５に示したように、成形型移動装置６の移動用アクチュエータ６２によって、移動型７２が後退（図５において左方へ移動）させられた開型位置において、前回に成形されたブラケット３が払いだされた後、移動用アクチュエータ６２を再度作動させて、移動型７２を斜め下方へ前進させる。移動型７２が成形位置まで移動すると、固定型７１と移動型７２との間に、ブラケット３の外形と一致した形状のキャビティ７３が形成される（図６示）。   Next, a method for joining the bracket 3 using the molding device 4 to the trim board 2 will be described with reference to FIGS. First, as shown in FIG. 5, the molding was performed last time at the open position where the movable mold 72 was moved backward (moved leftward in FIG. 5) by the moving actuator 62 of the mold moving device 6. After the bracket 3 is paid out, the moving actuator 62 is actuated again to advance the movable die 72 diagonally downward. When the movable die 72 moves to the molding position, a cavity 73 having a shape that matches the outer shape of the bracket 3 is formed between the fixed die 71 and the movable die 72 (shown in FIG. 6).

それとともに、トリムボード２を基材２１側を上にして、図示しないコンベアーまたはロボット等により、その先端部が基体ガイド６６に当接する位置まで、図５において右方へと運搬する。この状態において、トリムボード２は押圧部８５の真上に位置しているため、基体搬送装置８の搬送用アクチュエータ８３を作動させることにより、押圧部８５を上昇させて、トリムボード２をクッション部８６上に載置させる。その後、押圧部８５の上昇を継続することにより、トリムボード２が固定型７１および移動型７２の下端部に当接し、キャビティ７３の開口７４を下方より塞ぐ（図７示）。この時、トリムボード２はクッション部８６と固定型７１および移動型７２とにより挟圧され、固定型７１の凸部７１ｃと移動型７２の突起部７２ｃは、トリムボード２の基材２１を押圧し、これに若干食い込んだ状態となる（図１１示）。   At the same time, the trim board 2 is conveyed rightward in FIG. 5 to the position where the tip end of the trim board 2 comes into contact with the substrate guide 66 by a conveyor or a robot (not shown). In this state, since the trim board 2 is located directly above the pressing portion 85, the pressing actuator 85 is raised by operating the transfer actuator 83 of the substrate transfer device 8, and the trim board 2 is moved to the cushion portion. 86. Thereafter, by continuing to raise the pressing portion 85, the trim board 2 comes into contact with the lower ends of the fixed die 71 and the movable die 72, and closes the opening 74 of the cavity 73 from below (shown in FIG. 7). At this time, the trim board 2 is clamped by the cushion portion 86 and the fixed die 71 and the movable die 72, and the convex portion 71 c of the fixed die 71 and the protrusion 72 c of the movable die 72 press the base material 21 of the trim board 2. However, this is slightly bitten (see FIG. 11).

次に、成形材料導入装置５の導入用アクチュエータ５３を作動させて押圧プランジャ５４を下降させ、溶融通路５７内の溶融した成形材料ＭＺを下方に向けて押圧して、ノズル５８によって上方からキャビティ７３内に所定圧で所定量射出する（図８示）。成形材料ＭＺはキャビティ７３内に行き渡った後、温度が低下して硬化が進行し、キャビティ７３内にブラケット３が成形される。この時、ノズル５８から注入された高温の成形材料ＭＺが、トリムボード２の基材２１の上に乗ることにより、ブラケット３の直下となる基材２１に含まれる熱可塑性樹脂が融解して成形材料ＭＺと互いに溶融しあい、また、基材２１の植物繊維間に熱可塑性樹脂材料が入り込むことで、接合部３３がトリムボード２に強固に接合される。上述したように、固定型７１の凸部７１ｃと移動型７２の突起部７２ｃが、トリムボード２の基材２１に食い込んでいるため、成形材料ＭＺが開口７４から漏出することがなく、その硬化後、トリムボード２上にブラケット３の接合部３３からバリがはみ出ることはない。   Next, the introduction actuator 53 of the molding material introducing device 5 is operated to lower the pressing plunger 54, and the molten molding material MZ in the melting passage 57 is pressed downward, and the cavity 73 is pressed from above by the nozzle 58. A predetermined amount is injected into the inside at a predetermined pressure (shown in FIG. 8). After the molding material MZ reaches the inside of the cavity 73, the temperature decreases and the curing proceeds, and the bracket 3 is molded in the cavity 73. At this time, when the high-temperature molding material MZ injected from the nozzle 58 is placed on the base material 21 of the trim board 2, the thermoplastic resin contained in the base material 21 immediately below the bracket 3 is melted and molded. The joint portion 33 is firmly joined to the trim board 2 by melting the material MZ and each other, and by the thermoplastic resin material entering between the plant fibers of the base material 21. As described above, since the convex portion 71c of the fixed die 71 and the protruding portion 72c of the movable die 72 bite into the base material 21 of the trim board 2, the molding material MZ does not leak from the opening 74 and is cured. Thereafter, no burr protrudes from the joint portion 33 of the bracket 3 on the trim board 2.

ブラケット３の成形後、成形型移動装置６は移動型７２を、下面７２ｄに対して後方斜め上向きに移動させて、ブラケット３から離型させ、再び開型位置まで移動させる（図９示）。移動型７２は、ブラケット３の立壁３１がアンダーカット部となっているために、後方へ型抜きをせざるを得ないのであるが、移動型７２を斜めに移動させて、傾斜面７２ｅを基材２１上に滑らせることにより、下面７２ｄから突起部７２ｃが突出していても、支障なく、ブラケット３から型抜きすることができる。その後、基体搬送装置８により押圧部８５を下降させ、トリムボード２と接合されたブラケット３を、固定型７１から下方に取り出す（図１０示）。これ以降は、成形型移動装置６により、再び移動型７２を前進させて、上述した工程を繰り返していく。   After the molding of the bracket 3, the molding die moving device 6 moves the movable die 72 obliquely upward and rearward with respect to the lower surface 72d, releases from the bracket 3, and again moves to the open position (shown in FIG. 9). The movable die 72 is forced to be removed rearward because the standing wall 31 of the bracket 3 is an undercut portion. However, the movable die 72 is moved obliquely, and the inclined surface 72e is used as a base. By sliding on the material 21, even if the protrusion 72c protrudes from the lower surface 72d, the die can be removed from the bracket 3 without any trouble. Thereafter, the pressing portion 85 is lowered by the substrate transport device 8, and the bracket 3 joined to the trim board 2 is taken out from the fixed die 71 (shown in FIG. 10). Thereafter, the movable die 72 is advanced again by the mold moving device 6 and the above-described steps are repeated.

本実施形態によれば、開口７４を取り囲む固定型７１および移動型７２の角部に、トリムボード２と当接する面７１ｄ、７２ｄから突出して、先端がトリムボード２の表面を押圧する凸部７１ｃおよび突起部７２ｃを設け、成形後、移動型７２をトリムボード２に対して斜め方向に移動させて離型させたことにより、成形後に、ブラケット３からバリを発生させることなく、また、冷却の際の熱収縮によるトリムボード２の変形を防止して、その品質を向上できる。また、凸部７１ｃおよび突起部７２ｃによって、確実にバリを断つことができるため、トリムボード２を成形型７１、７２に強く押圧する必要がなく、成形時に、成形型７１、７２に対し、トリムボード２を位置管理するのみで良好な成形が可能となる。また、突起部７２ｃの型抜きが容易となり、成形型７１、７２を簡素にすることができるため、低コストなドアトリム１を製造することができる。また、アンダーカット部である立壁３１からの移動型７２の型抜きが容易となり、かつ、ブラケット３の移動型７２側へのバリ発生を防止できる。   According to the present embodiment, the convex portions 71 c that protrude from the surfaces 71 d and 72 d in contact with the trim board 2 at the corners of the fixed die 71 and the movable die 72 that surround the opening 74 and whose tips press the surface of the trim board 2. In addition, after the molding, the movable die 72 is moved obliquely with respect to the trim board 2 and released from the mold so that no burrs are generated from the bracket 3 after the molding. It is possible to prevent the trim board 2 from being deformed by heat shrinkage at the time, and to improve its quality. Further, since the burr can be surely cut off by the convex portion 71c and the protruding portion 72c, it is not necessary to strongly press the trim board 2 against the molding dies 71, 72, and the trim 71 against the molding dies 71, 72 is trimmed at the time of molding. Good molding is possible only by managing the position of the board 2. In addition, the protrusion 72c can be easily removed from the mold, and the molding dies 71 and 72 can be simplified, so that the low-cost door trim 1 can be manufactured. Further, it is easy to remove the movable die 72 from the standing wall 31 that is the undercut portion, and it is possible to prevent the occurrence of burrs on the movable die 72 side of the bracket 3.

また、トリムボード２は植物繊維と、この植物繊維を繋ぐバインダ樹脂とからなり、ブラケット３の成形材料ＭＺはバインダ樹脂と同種の樹脂材料にて形成されたことにより、ブラケット３とバインダ樹脂との結合力が増大するとともに、植物繊維の間に成形材料ＭＺが入り込むことにより、アンカ効果を期待できるため、ブラケット３とトリムボード２との接合力がいっそう増大する。   Further, the trim board 2 is made of a vegetable fiber and a binder resin for connecting the vegetable fiber, and the molding material MZ of the bracket 3 is formed of the same resin material as the binder resin, so that the bracket 3 and the binder resin are Since the bonding force increases and the molding material MZ enters between the plant fibers, an anchor effect can be expected, so that the bonding force between the bracket 3 and the trim board 2 further increases.

Moreover, the tip part shape of the convex part 71c is good also as a semicircle, as shown to FIG. 12 (B). These can be determined in consideration of the surface material, properties, etc. of the trim board 2 pressed by the protrusion 71c.
