Description

本発明は、ドアトリムやインストルメントパネル等の表皮一体樹脂成形品を成形する成形装置に関する。   The present invention relates to a molding apparatus for molding a skin-integrated resin molded product such as a door trim or an instrument panel.

従来より、車両用内装品には、例えば、特許文献１に開示されているように、表皮材の裏面側にパネル状をなす樹脂製基材を射出成形によって一体的に成形して得た表皮一体樹脂成形品からなるものがある。   2. Description of the Related Art Conventionally, as disclosed in Patent Document 1, for example, a skin material obtained by integrally molding a resin base material having a panel shape on the back surface side of a skin material by injection molding, as disclosed in Patent Document 1 Some are made of integral resin molded products.

ところで、車両用内装品の１つであるドアトリムに適用される表皮一体樹脂成形品の１つに、基材表面を上下に二分した下方の領域、すなわち、車両に乗車する乗員の腕や肘が接触する領域のみ布や合皮からなる柔軟性を有する表皮材で覆ったものがあり、このような表皮一体樹脂成形品を成形する成形装置として、例えば、上型及び該上型に対向配置された下型からなる成形型と、水平方向に対向配置された一対の把持具とを備え、上記上型の成形面における両把持具の並設方向と交差する水平方向の一方側領域にその縁部が上記両把持具に把持された表皮材を対応させた状態で上記成形型を型閉じさせながらキャビティ内に熱可塑性樹脂を充填して固化させることにより基材表面に表皮材が被着された表皮一体樹脂成形品を一体成形するものが知られている。   By the way, in one of the skin-integrated resin molded products applied to a door trim that is one of the interior parts for vehicles, there is a lower region obtained by dividing the base material surface into two parts, that is, the arms and elbows of passengers who ride on the vehicle.

しかし、上述の如き成形装置では、成形型のキャビティ内において熱可塑性樹脂が固化する際に熱収縮するので、その熱収縮によって基材表面に被着する表皮材に圧縮力が加わる。また、ドアトリムの表面は、乗員の腕や肘に対応するよう緩やかな湾曲形状をなし、この湾曲形状によっても成形の際に表皮材に圧縮力が発生する。すると、布や合皮からなる柔軟性を有する表皮材は伸縮し難い材質であるため、表皮材に対して両把持具によってテンションが加わっていない方向に上述の如き圧縮力が加わり、その値が許容値を超えてしまうと、表皮材が断面波状に変化して成形品表面にシワが発生してしまう。   However, in the molding apparatus as described above, heat shrinkage occurs when the thermoplastic resin solidifies in the cavity of the mold, so that compressive force is applied to the skin material to be deposited on the substrate surface by the heat shrinkage. Further, the surface of the door trim has a gently curved shape so as to correspond to the occupant's arms and elbows, and this curved shape also generates a compressive force on the skin material during molding. Then, since the flexible skin material made of cloth or synthetic leather is a material that is difficult to expand and contract, the compression force as described above is applied to the skin material in a direction in which no tension is applied by both gripping tools, and the value is If the allowable value is exceeded, the skin material changes into a corrugated cross section and wrinkles occur on the surface of the molded product.

本発明は、斯かる点に鑑みてなされたものであり、その目的とするところは、樹脂製基材表面に柔軟性表皮材が被着された表皮一体樹脂成形品をその表面にシワを発生させずに成形する成形装置を提供することにある。   The present invention has been made in view of such a point, and the object of the present invention is to generate a wrinkle on the surface of a resin-integrated resin molded product in which a flexible skin material is applied to the surface of a resin base material. An object of the present invention is to provide a molding apparatus that performs molding without causing the molding to occur.

上記の目的を達成するために、本発明は、成形時において、表皮材に対して両把持具の並設方向だけでなく、両把持具の並設方向と交差する水平方向にもテンションが加わるよう工夫したことを特徴とする。   In order to achieve the above object, the present invention applies tension to the skin material not only in the direction in which the two gripping tools are juxtaposed but also in the horizontal direction that intersects the direction in which the two gripping tools are juxtaposed during molding. It is characterized by such contrivance.

具体的には、上型及び該上型に対向配置された下型を有する成形型と、水平方向に対向配置された一対の把持手段とを備え、上記上型及び上記下型のいずれか一方の成形面は、上記両把持手段の並設方向と交差する水平方向に第１領域と第２領域とに区分けされ、上記両把持手段にその縁部が把持された柔軟性表皮材を上記第１領域に対応させた状態で上記成形型を型閉じさせながらキャビティ内に熱可塑性樹脂を充填して固化させることにより樹脂製基材表面に上記表皮材が被着された表皮一体樹脂成形品を一体成形する成形装置において、次のような解決手段を講じた。   Specifically, it comprises a molding die having an upper die and a lower die arranged opposite to the upper die, and a pair of gripping means arranged opposite to each other in the horizontal direction, and either one of the upper die or the lower die The molding surface is divided into a first region and a second region in a horizontal direction intersecting with the side-by-side direction of both gripping means, and the flexible skin material having the gripped edges by the gripping means is the first surface. A skin-integrated resin molded article in which the skin material is adhered to the surface of a resin base material by filling the cavity with a thermoplastic resin while solidifying the mold in a state corresponding to one region. In the molding apparatus for integrally molding, the following solutions were taken.

すなわち、第１の発明では、上記上型及び上記下型のいずれか他方には、上記キャビティ内に熱可塑性樹脂を充填して固化させる際、その成形面から出没した状態で上記上型及び上記下型のいずれか一方の成形面における上記第１領域の上記第２領域との連続部分とで上記表皮材の縁部を挟持する挟持手段が設けられていることを特徴とする。   That is, in the first invention, when either the upper mold or the lower mold is filled with the thermoplastic resin in the cavity and solidified, the upper mold and the lower mold are in a state where they protrude from the molding surface. It is characterized in that clamping means is provided for clamping the edge of the skin material with a continuous part of the first area on the molding surface of one of the lower molds with the second area.

第２の発明では、第１の発明において、上記挟持手段は、上下動可能なブロック型と、該ブロック型を上方付勢する付勢手段とを備え、上記成形型が型閉じする際、上記ブロック型が上記付勢手段の付勢力により上記表皮材を上記上型及び下型のいずれか一方の成形面に押し付けて挟持することを特徴とする。   According to a second invention, in the first invention, the clamping means includes a block mold that can move up and down and a biasing means that biases the block mold upward, and when the molding mold closes, The block mold is configured to press and hold the skin material against one of the molding surfaces of the upper mold and the lower mold by the biasing force of the biasing means.

第３の発明では、第２の発明において、上記上型及び上記下型のいずれか一方の成形面における上記第１領域の上記第２領域との連続部分には、突条部が突設される一方、上記上型及び上記下型のいずれか他方の成形面には、上記成形型が型閉じした状態で上記突条部が入り込む凹条溝が凹設され、該凹条溝には、上記ブロック型を収容可能な収容凹部が設けられ、上記ブロック型は、上記成形型が型閉じする際、上記突条部の先端とで上記表皮材を挟持した状態で上記突条部に押圧されて上記収容凹部に収容されることを特徴とする。   According to a third aspect, in the second aspect, a ridge portion projects from a continuous part of the first region with the second region on one of the molding surfaces of the upper die and the lower die. On the other hand, on the other molding surface of the upper die and the lower die, a concave groove into which the protruding portion enters in the state where the molding die is closed is provided in the concave groove, An accommodation recess capable of accommodating the block mold is provided, and the block mold is pressed against the protrusion in a state in which the skin material is sandwiched between the tip of the protrusion when the mold is closed. And is housed in the housing recess.

第４の発明では、第３の発明において、上記ブロック型には、上記成形型が型閉じする際、上記突条部先端とで上記表皮材を挟持する挟持面と、上記表皮材を支持して上記上型及び上記下型のいずれか一方の成形面の第１領域における上記突条部基端側周辺に上記表皮材を沿わせる支持面とが設けられていることを特徴とする。   According to a fourth invention, in the third invention, the block mold supports the skin material and a clamping surface that sandwiches the skin material with the tip of the protrusion when the mold is closed. In addition, a support surface is provided around the base end side of the protruding portion in the first region of the molding surface of one of the upper die and the lower die.

第５の発明では、第１から第４のいずれか１つの発明において、上記上型及び上記下型のいずれか一方の成形面は、その上記両把持手段の並設方向と交差する水平方向の一方側を上記第１領域とする一方、他方側を上記第２領域とし、上記上型及び上記下型のいずれか他方には、上記キャビティ内に熱可塑性樹脂を充填して固化させる際、その成形面から出没した状態で上記第１領域の反第２領域側の縁部に上記表皮材の縁部を押し付ける押付手段が設けられていることを特徴とする。   In a fifth invention, in any one of the first to fourth inventions, the molding surface of one of the upper mold and the lower mold is in a horizontal direction intersecting the juxtaposing direction of the both gripping means. When one side is the first region, the other side is the second region, and the other of the upper mold and the lower mold is filled with the thermoplastic resin in the cavity and solidified, Pressing means for pressing the edge of the skin material on the edge of the first region opposite to the second region in a state of protruding from the molding surface is provided.

第６の発明では、第５の発明において、上記押付手段は、上下に伸縮するピストンロッドを有する流体圧シリンダであり、上記成形型が型閉じする際、上記ピストンロッドの先端が上記上型及び上記下型のいずれか一方の成形面に上記表皮材を押し付けることを特徴とする。   According to a sixth invention, in the fifth invention, the pressing means is a fluid pressure cylinder having a piston rod that expands and contracts vertically, and when the mold is closed, the tip of the piston rod is the upper mold and The skin material is pressed against one of the molding surfaces of the lower mold.

第１の発明では、成形型のキャビティ内に熱可塑性樹脂を充填して固化させる際、両把持具で把持していない表皮材の縁部を挟持手段が挟持するようになるので、表皮材に圧縮力が加わっても両把持具の並設方向だけでなくその並設方向と交差する水平方向にも表皮材が縮まなくなり、圧縮力が許容値を超えて表皮材が縮むことで成形品の表面にシワが発生するといったことを防ぐことができる。   In the first invention, when the thermoplastic resin is filled in the cavity of the mold and solidified, the gripping means grips the edge of the skin material that is not gripped by both grippers. Even if compressive force is applied, the skin material will not shrink not only in the direction in which both grippers are juxtaposed, but also in the horizontal direction intersecting the juxtaposed direction, and the compressive force will exceed the allowable value and the skin material will shrink. It is possible to prevent wrinkles from occurring on the surface.

第２の発明では、成形型の型閉じ動作を利用して挟持手段が表皮材を挟持するので、両把持具で把持していない表皮材の縁部を挟持するために別途駆動源を用意する必要がなく、設備がシンプルであるとともに、低コスト、且つ、コンパクトな装置にできる。   In the second invention, since the clamping means clamps the skin material using the mold closing operation of the molding die, a separate drive source is prepared to clamp the edge of the skin material not gripped by both grippers. There is no need, the equipment is simple, and the apparatus can be made low in cost and compact.

第３の発明では、基材表面における表皮材が被着された領域と被着されていない領域との境界において、表皮材の縁部が基材内部に埋め込まれる。したがって、表皮材の縁部が基材表面側に露出しなくなり、成形品の見栄えを良くすることができる。また、成形型の型閉じ状態でキャビティ内にブロック型が飛び出さなくなるので、キャビティ内に熱可塑性樹脂を偏りなく埋めてブロック型による欠落部分のない基材を成形することができる。   In 3rd invention, the edge part of a skin material is embedded in the inside of a base material in the boundary of the area | region where the skin material was adhere | attached on the surface of a base material, and the area | region which is not attached. Therefore, the edge of the skin material is not exposed to the substrate surface side, and the appearance of the molded product can be improved. In addition, since the block mold does not protrude into the cavity when the mold is closed, it is possible to mold the base material without any missing portion due to the block filled with the thermoplastic resin.

第４の発明では、キャビティ内に熱可塑性樹脂を充填する際、表皮材が突条部の側面に沿うようになるので、一体成形後の成形品において、表皮材が被着された領域と被着されていない領域との境界の見栄えをさらに良くすることができる。   In the fourth aspect of the invention, when the thermoplastic resin is filled into the cavity, the skin material is along the side surface of the ridge portion. Therefore, in the molded product after the integral molding, the region where the skin material is deposited The appearance of the boundary with the undressed area can be further improved.

第５の発明では、成形型のキャビティ内に熱可塑性樹脂を充填して固化させる際、両把持具で把持していない表皮材の縁部を挟持手段だけでなく押付手段でも固定するので、表皮材に圧縮力が多方向に加わっても確実に成形品表面のシワを無くすことができる。   In the fifth aspect of the invention, when the mold cavity is filled with the thermoplastic resin and solidified, the edge of the skin material not gripped by both grippers is fixed not only by the clamping means but also by the pressing means. Even if compressive force is applied to the material in multiple directions, wrinkles on the surface of the molded product can be surely eliminated.

第６の発明では、流体圧によって表皮材を上型及び下型のいずれか一方の成形面に強固に押し当てることができるので、圧縮力が加わった表皮材の収縮を確実に防いで成形品表面のシワの発生を止めることができる。   In the sixth aspect of the invention, the skin material can be firmly pressed against the molding surface of either the upper die or the lower die by the fluid pressure, so that the shrinkage of the skin material to which the compressive force is applied is surely prevented. Generation of surface wrinkles can be stopped.

It has come to be.

さらに、上記突条部５ｃは、上記成形型７が型閉じする際（上記キャビティ７ａ内に熱可塑性樹脂１１を充填して固化させる際）、その先端と上記ブロック型４４の第２面４４ｂとで上記表皮材１０ａを挟持した状態で上記第２コイルバネＳｐ１の付勢力に抗して上記ブロック型４４を押圧して上記幅広部４１ａに収容させるとともに上記凹条溝４１に入り込むようになっている。すなわち、上記ブロック型４４は、上記成形型７が型閉じする際、上記突条部５ｃとで上記表皮材１０ａを挟持した状態で上記突条部５ｃに押圧されて上記幅広部４１ａに収容されるようになっている。   Further, when the molding die 7 is closed (when the cavity 7a is filled with the thermoplastic resin 11 and solidified), the protrusion 5c has a tip thereof and a second surface 44b of the block die 44. In this state, the block mold 44 is pressed against the urging force of the second coil spring Sp1 in a state where the skin material 10a is held, and is accommodated in the wide portion 41a and enters the concave groove 41. . That is, when the mold 7 is closed, the block die 44 is pressed by the ridge 5c in a state of sandwiching the skin material 10a with the ridge 5c and is accommodated in the wide portion 41a. It has become so.

それに加えて、上記成形型７が型閉じする際（上記キャビティ７ａ内に熱可塑性樹脂１１を充填して固化させる際）、上記ブロック型４４の第１面４４ａは、上記表皮材１０ａを支持して上記上側成形面５ａの表皮材対応領域Ｒ１における上記突条部５ｃ基端側周辺に上記表皮材１０ａを沿わせるとともに、上記成形型７の型閉じ状態で上記幅広部４１ａの開口周りと面一になるようになっている。   In addition, when the mold 7 closes (when the cavity 7a is filled with the thermoplastic resin 11 and solidified), the first surface 44a of the block mold 44 supports the skin material 10a. Then, the skin material 10a is arranged around the base end side of the protrusion 5c in the skin material corresponding region R1 of the upper molding surface 5a, and the opening and the surface of the wide portion 41a are closed when the molding die 7 is closed. It is supposed to be one.

そして、上記成形型７を型閉じさせながら上記樹脂注入機６により上記キャビティ７ａ内に熱可塑性樹脂１１を充填して固化させることにより、上記基材１０ｂ表面に上記表皮材１０ａが被着されたドアトリム１０が一体成形されるようになっている。   Then, the skin material 10a was deposited on the surface of the base material 10b by filling the cavity 7a with the thermoplastic resin 11 and solidifying the resin 7 with the mold 7 closed. The door trim 10 is integrally formed.

次に、上記ドアトリム１０の成形方法について説明する。   Next, a method for forming the door trim 10 will be described.

まず初めに、図１及び図２に示すように、成形型７が型開きした状態において、各収容溝４ｅから各第１コイルバネ４ｄの付勢力により上方に飛び出た把持棒４ｃに帯状の表皮材１０ａの長手方向両端縁を保持させる。   First, as shown in FIGS. 1 and 2, in the state where the mold 7 is opened, a strip-shaped skin material is formed on the gripping rod 4c that protrudes upward from the respective housing groove 4e by the biasing force of each first coil spring 4d. The both longitudinal edges of 10a are held.

次に、上記昇降台３を下降させることにより上記上型５を下動させる。すると、上記各把持棒４ｃが上記第１コイルバネ４ｄの付勢力により上記表皮材１０ａを上記上型５の上側分割面５ｂに押し付けて把持するとともに、上記表皮材１０ａを上記上側成形面５ａの表皮材対応領域Ｒ１に対応させる。   Next, the upper die 5 is moved down by lowering the elevator 3. Then, each gripping rod 4c presses and grips the skin material 10a against the upper split surface 5b of the upper mold 5 by the biasing force of the first coil spring 4d, and the skin material 10a is gripped by the skin of the upper molding surface 5a. It corresponds to the material corresponding region R1.

次いで、上記上型５をさらに下動させる。すると、上側分割面５ｂが上記各第１コイルバネ４ｄの付勢力に抗して上記各把持棒４ｃを下方に押す。   Next, the upper mold 5 is further moved down. Then, the upper divided surface 5b pushes the grip bars 4c downward against the urging force of the first coil springs 4d.

上記上型５をさらに下動させると、図３に示すように、上記下側成形面４ａから出没するピストンロッド４７ａの上端が上記表皮材対応領域Ｒ１の反表皮材非対応領域Ｒ２側の縁部に上記表皮材１０ａの縁部を押し付けるとともに、上記突条部５ｃの先端が上記表皮材１０ａの表皮材非対応領域Ｒ２側の縁部に接触して上記ブロック型４４の第１面４４ａに上記表皮材１０ａを沿わす。   When the upper die 5 is further moved downward, as shown in FIG. 3, the upper end of the piston rod 47a protruding and retracting from the lower molding surface 4a is the edge of the skin material corresponding region R1 on the side opposite to the anti-skin material R2 The edge of the skin material 10a is pressed against the surface, and the tip of the ridge 5c comes into contact with the edge of the skin material 10a on the skin material non-corresponding region R2 side to contact the first surface 44a of the block mold 44. Along the skin material 10a.

その後、上記上型５をさらに下動させると、図４に示すように、上記ピストンロッド４７ａが上記上側成形面５ａに押圧されて次第に縮むとともに、上記突条部５ｃ先端が上記ブロック型４４の第２面４４ｂとで上記表皮材１０ａを挟持し、且つ、上記ブロック型４４の第１面４４ａが上記表皮材１０ａを支持して上記上側成形面５ａの表皮材対応領域Ｒ１における上記突条部５ｃ基端側周辺に上記表皮材１０ａを沿わせる。   Thereafter, when the upper die 5 is further moved downward, the piston rod 47a is pressed against the upper molding surface 5a and gradually contracts, as shown in FIG. The skin material 10a is sandwiched between the second surface 44b, and the first surface 44a of the block mold 44 supports the skin material 10a, and the ridge portion in the skin material corresponding region R1 of the upper molding surface 5a. 5c The skin material 10a is placed around the base end side.

しかる後、上記上型５をさらに下動させると、図５に示すように、上記ピストンロッド４７ａが上記上側成形面５ａに押圧されてさらに縮むとともに、上記突条部５ｃ先端が、その先端と上記ブロック型４４の第２面４４ｂとで上記表皮材１０ａを挟持した状態で上記第２コイルバネＳｐ１の付勢力に抗して上記ブロック型４４を押圧して上記幅広部４１ａに収容させ始める。   Thereafter, when the upper die 5 is further moved downward, as shown in FIG. 5, the piston rod 47a is pressed against the upper molding surface 5a and further contracts, and the tip of the ridge portion 5c is The block mold 44 is pressed against the urging force of the second coil spring Sp1 while the skin material 10a is sandwiched between the second surface 44b of the block mold 44 and begins to be accommodated in the wide portion 41a.

そして、上記成形型７の型閉じ動作中に上記上側成形面５ａと上記下側成形面４ａとでキャビティ７ａが形成されると、当該キャビティ７ａ内に上記樹脂注入機６により熱可塑性樹脂１１を注入し始める。   When the cavity 7a is formed by the upper molding surface 5a and the lower molding surface 4a during the mold closing operation of the molding die 7, the thermoplastic resin 11 is introduced into the cavity 7a by the resin injection machine 6. Start infusion.

しかる後、上記上型５をさらに下動させつつ上記樹脂注入機６によりキャビティ７ａ内に熱可塑性樹脂１１を注入し続けると、上記ブロック型４４が上記幅広部４１ａに収容されて上記第１面４４ａが上記幅広部４１ａの開口周りと面一になるとともに、ブロック型４４と上記表皮材１０ａとの間に熱可塑性樹脂１１が入り込み、キャビティ７ａ内に熱可塑性樹脂１１が偏りなく充填される。   Thereafter, when the thermoplastic resin 11 is continuously injected into the cavity 7a by the resin injection machine 6 while the upper die 5 is further moved downward, the block die 44 is accommodated in the wide portion 41a and the first surface. 44a becomes flush with the periphery of the opening of the wide portion 41a, the thermoplastic resin 11 enters between the block mold 44 and the skin material 10a, and the thermoplastic resin 11 is uniformly filled in the cavity 7a.

そして、キャビティ７ａ内で熱可塑性樹脂１１を固化させるために成形型７を型閉じさせた状態で所定時間経過させ、その後、図７に示すように成形型７を型開きし、一体成形された上記ドアトリム１０を成形型７内から脱型する。すると、上側成形面５ａに上方から押圧されて厚みが薄くなっていた表皮材１０ａが膨らみ、一体成形されたドアトリム１０の上記突条部５ｃに対応する部分が上記表皮材１０ａに塞がれてドアトリム１０表面側の見栄えがさらに良くなる。   Then, in order to solidify the thermoplastic resin 11 in the cavity 7a, the mold 7 is closed for a predetermined time, and then the mold 7 is opened and integrally molded as shown in FIG. The door trim 10 is removed from the mold 7. Then, the skin material 10a, which has been pressed from the upper side to the upper molding surface 5a and thinned, swells, and a portion corresponding to the protruding portion 5c of the integrally formed door trim 10 is blocked by the skin material 10a. The appearance of the surface side of the door trim 10 is further improved.

以上より、本発明の実施形態によると、成形型７のキャビティ７ａ内に熱可塑性樹脂１１を充填して固化させる際、両把持具４０で把持していない表皮材１０ａの縁部を挟持手段１２が挟持するようになるので、表皮材１０ａに圧縮力が加わっても両把持具４０の並設方向だけでなくその並設方向と交差する水平方向にも表皮材１０ａが縮まなくなり、圧縮力が許容値を超えて表皮材１０ａが縮むことでドアトリム１０の表面にシワが発生するといったことを防ぐことができる。   As described above, according to the embodiment of the present invention, when the thermoplastic resin 11 is filled in the cavity 7 a of the mold 7 and solidified, the edge of the skin material 10 a that is not gripped by the gripping tools 40 is sandwiched by the means 12. Therefore, even if a compressive force is applied to the skin material 10a, the skin material 10a is not contracted not only in the direction in which both the gripping tools 40 are juxtaposed but also in the horizontal direction intersecting the juxtaposed direction, and the compressive force is reduced. It is possible to prevent wrinkles from occurring on the surface of the door trim 10 due to the shrinkage of the skin material 10a beyond the allowable value.

また、成形型７の型閉じ動作を利用して挟持手段１２が表皮材１０ａを挟持するので、両把持具４０で把持していない表皮材１０ａの縁部を挟持するために別途駆動源を用意する必要がなく、設備がシンプルであるとともに、低コスト、且つ、コンパクトな成形装置１にできる。   Further, since the clamping means 12 clamps the skin material 10a using the mold closing operation of the molding die 7, a separate drive source is prepared to clamp the edge of the skin material 10a that is not gripped by both gripping tools 40. Therefore, the equipment is simple, and the molding apparatus 1 can be made at a low cost and a compact size.

また、基材１０ｂ表面における表皮材１０ａが被着された領域と被着されていない領域との境界において、表皮材１０ａの縁部が基材１０ｂ内部に埋め込まれる。したがって、表皮材１０ａの縁部が基材１０ｂ表面側に露出しなくなり、ドアトリム１０の見栄えを良くすることができる。また、成形型７の型閉じ状態でキャビティ７ａ内にブロック型４４が飛び出さなくなるので、キャビティ７ａ内に熱可塑性樹脂１１を偏りなく埋めてブロック型４４による欠落部分のない基材１０ｂを成形することができる。   Moreover, the edge part of the skin material 10a is embedded in the inside of the base material 10b in the boundary of the area | region where the skin material 10a was adhere | attached on the surface of the base material 10b, and the area | region which is not adhere | attached. Therefore, the edge part of the skin material 10a is not exposed to the base material 10b surface side, and the appearance of the door trim 10 can be improved. Further, since the block mold 44 does not protrude into the cavity 7a when the mold 7 is closed, the thermoplastic resin 11 is evenly filled in the cavity 7a to form the base material 10b having no missing portion by the block mold 44. be able to.

さらに、キャビティ７ａ内に熱可塑性樹脂１１を充填する際、表皮材１０ａが突条部５ｃの側面に沿うようになるので、一体成形後のドアトリム１０において、表皮材１０ａにおける被着された領域と被着されていない領域との境界の見栄えをさらに良くすることができる。   Further, when the thermoplastic resin 11 is filled in the cavity 7a, the skin material 10a comes along the side surface of the protruding portion 5c. Therefore, in the door trim 10 after the integral molding, The appearance of the boundary with the non-attached area can be further improved.

それに加えて、成形型７のキャビティ７ａ内に熱可塑性樹脂１１を充填して固化させる際、両把持具４０で把持していない表皮材１０ａの縁部を挟持手段１２だけでなく流体圧シリンダ４７でも固定するので、表皮材１０ａに圧縮力が多方向に加わっても確実にドアトリム１０表面のシワを無くすことができる。   In addition, when the thermoplastic resin 11 is filled in the cavity 7a of the mold 7 and solidified, the edge of the skin material 10a not gripped by both gripping tools 40 is not only the clamping means 12 but also the fluid pressure cylinder 47. However, since they are fixed, wrinkles on the surface of the door trim 10 can be surely eliminated even if compressive forces are applied to the skin material 10a in multiple directions.

そして、流体圧シリンダ４７による流体圧によって表皮材１０ａを上型５の上側成形面５ａに強固に押し当てることができるので、圧縮力が加わった表皮材１０ａの収縮を確実に防いでドアトリム１０表面のシワの発生を止めることができる。   Since the skin material 10a can be firmly pressed against the upper molding surface 5a of the upper mold 5 by the fluid pressure from the fluid pressure cylinder 47, the surface of the door trim 10 is reliably prevented from shrinking by applying a compressive force. The generation of wrinkles can be stopped.

尚、本発明の実施形態では、基材１０ｂの表面に布製の表皮材１０ａを被着させているが、基材１０ｂの表面に被着させる表皮材１０ａの種類はこれに限らず、例えば、合皮製であってもよいし、柔軟性を有するものであればよい。   In the embodiment of the present invention, the cloth skin material 10a is attached to the surface of the base material 10b. However, the type of the skin material 10a to be applied to the surface of the base material 10b is not limited to this. For example, It may be made of synthetic leather or may be flexible.

また、本発明の実施形態では、上型５の上側成形面５ａに表皮材１０ａを対応させて一体成形しているが、下型４の下側成形面４ａに表皮材１０ａを対応させて一体成形してもよい。その際、挟持手段１２のブロック型４４及び流体圧シリンダ４７のピストンロッド４７ａは、上側成形面５ａから出没するようになる。   Further, in the embodiment of the present invention, the skin material 10a is made to correspond to the upper molding surface 5a of the upper mold 5 and integrally molded, but the skin material 10a is made to correspond to the lower molding surface 4a of the lower mold 4 and integrated. You may shape | mold. At that time, the block mold 44 of the clamping means 12 and the piston rod 47a of the fluid pressure cylinder 47 come and go from the upper molding surface 5a.

さらに、本発明の実施形態では、上側成形面５ａをその両把持具４０の並設方向と交差する水平方向の一方側を表皮材対応領域Ｒ１とし、他方側を表皮材非対応領域Ｒ２としているが、２つの領域に区分けした場合だけでなく、例えば、上側成形面５ａにおける両把持具４０の並設方向と交差する水平方向中央部分を表皮材対応領域Ｒ１とし、その水平方向両側を表皮材非対応領域Ｒ２とした場合においても、本願の成形装置１を適用することができる。   Furthermore, in the embodiment of the present invention, in the upper molding surface 5a, one side in the horizontal direction intersecting the direction in which both the gripping tools 40 are arranged is the skin material corresponding region R1, and the other side is the skin material non-corresponding region R2. However, not only in the case of dividing into two regions, for example, the horizontal center portion intersecting the juxtaposed direction of both gripping tools 40 on the upper molding surface 5a is defined as the skin material corresponding region R1, and both sides in the horizontal direction are the skin material. Even in the case of the non-corresponding region R2, the molding apparatus 1 of the present application can be applied.

それに加えて、本発明の実施形態では、ドアトリム１の成形に本発明の成形装置１を適用したが、その他の車両用内装品、例えば、インストルメントパネル等の成形に本発明の成形装置１を適用することができる。   In addition, in the embodiment of the present invention, the molding apparatus 1 of the present invention is applied to the molding of the door trim 1, but the molding apparatus 1 of the present invention is applied to molding of other vehicle interior parts such as instrument panels. Can be applied.
