Description

本発明は、真空成形を行うに際し、成形型の端部にシート状の成形素材の端部を合わせた状態で成形型および成形素材の各端部を挟むことで、成形素材を成形型に固定する成形素材固定具に関する。   In the present invention, when vacuum forming is performed, the molding material is fixed to the molding die by sandwiching the molding die and each end of the molding material with the end of the sheet-like molding material aligned with the end of the molding die. The present invention relates to a molding material fixture.

従来、熱可塑性樹脂などのシート状の素材を成形する方法として、真空成形方法が知られており、この真空成形方法を用いて、車両のインストルメントパネルやコンソールなどの各種成形品が成形されている（例えば、特許文献１）。
真空成形方法は、熱可塑性のシート状の成形素材を加熱して型面に被せて、成形素材と型面との間に存在する空気を吸引することで型面に成形素材を密着させて成形素材を成形する方法である。 Conventionally, a vacuum forming method is known as a method for forming a sheet-like material such as a thermoplastic resin, and various molded products such as an instrument panel and a console of a vehicle are formed using this vacuum forming method. (For example, Patent Document 1).
The vacuum forming method heats a thermoplastic sheet-shaped molding material to cover the mold surface, and draws the air that exists between the molding material and the mold surface to bring the molding material into close contact with the mold surface. This is a method of forming a material.

このような真空成形方法は、例えば次のように行なわれる。図６はシート状の成形素材を成形する準備段階を示した斜視図であり、図７はシート状の成形素材を成形する段階を示した断面図である。
先ず、シート状の成形素材３を、図６に示したように、略方形状の上枠１０１と、上枠１０１と同形の下枠１０２とで挟む。次に、複数の万力１０３で上枠１０１と下枠１０２との縁部を複数箇所挟む。その後、シート状の成形素材３を熱変形温度まで加熱して軟化させるとともに、転写したい形を有する成形型１０４に成形素材３を被せる。そして、図７に示すように、シート状の成形素材３と型面との間の空気を吸引して、成形型１０４の型面に成形素材３を密着させて成形を行っていた。 Such a vacuum forming method is performed as follows, for example. FIG. 6 is a perspective view showing a preparation stage for molding a sheet-shaped molding material, and FIG. 7 is a cross-sectional view showing a stage for molding the sheet-shaped molding material.
First, as shown in FIG. 6, the sheet-shaped molding material 3 is sandwiched between a substantially rectangular upper frame 101 and a lower frame 102 having the same shape as the upper frame 101. Next, a plurality of edges of the upper frame 101 and the lower frame 102 are sandwiched by a plurality of vises 103. Thereafter, the sheet-shaped molding material 3 is heated to the heat deformation temperature and softened, and the molding material 3 is placed on a molding die 104 having a shape to be transferred. Then, as shown in FIG. 7, the air between the sheet-shaped molding material 3 and the mold surface is sucked, and the molding material 3 is brought into close contact with the mold surface of the molding die 104 to perform molding.

また、次のように、成形素材３を成形型２に固定して真空成形が行なわれている。
図８は、シート状の成形素材３を成形型２に固定する形態を示した斜視図である。図８に示すように、シート状の成形素材３を成形型２に被せ、シート状の成形素材３の端部３ａと成形型２の端部２ａとを合わせて金属製のクリップ１０５で留め、クリップ１０５の柄１０５ａを脱着して、真空成形を行なっていた。 Further, vacuum forming is performed by fixing the molding material 3 to the molding die 2 as follows.
FIG. 8 is a perspective view showing a form in which the sheet-like molding material 3 is fixed to the molding die 2. As shown in FIG. 8, the sheet-shaped molding material 3 is placed on the molding die 2, and the end 3 a of the sheet-shaped molding material 3 and the end 2 a of the molding die 2 are combined and fastened with a metal clip 105. The handle 105a of the clip 105 was removed and vacuum forming was performed.

特開２００３−１１７９９３号公報JP 2003-117993 A

しかしながら、図７に示したように、上枠１０１と下枠１０２とでシート状の成形素材３を挟んで、万力１０３で挟掴した場合には、シート状の成形素材３を成形型１０４に確実に固定することができず、成形素材３と成形型１０４との位置ズレが生じる。
また、図８に示したように、クリップ１０５でシート状の成形素材３と成形型２とを固定する場合には、クリップ１０５の柄１０５ａを取り外して真空成形を行っていたので、柄１０５ａの脱着工程と、真空成形後にクリップ１０５を外すために柄１０５ａの装着工程が必要となり、手間がかかってしまう。
さらには、クリップ１０５は金属製であるので、クリップ１０５を成形型２および成形素材３の各端部２ａ，３ａに装着したり脱着したりする際にシート状の成形素材３に傷が付くと、成形品の商品価値を低下させてしまう。 However, as shown in FIG. 7, when the sheet-shaped molding material 3 is sandwiched between the upper frame 101 and the lower frame 102 and is clamped by the vise 103, the sheet-shaped molding material 3 is molded into the molding die 104. Cannot be securely fixed to each other, and a positional deviation between the molding material 3 and the molding die 104 occurs.
Further, as shown in FIG. 8, when the sheet-shaped molding material 3 and the mold 2 are fixed with the clip 105, the handle 105a of the clip 105 is removed and vacuum forming is performed. The attachment / detachment step and the attachment step of the handle 105a are required to remove the clip 105 after the vacuum forming, which is troublesome.
Furthermore, since the clip 105 is made of metal, when the clip 105 is attached to or detached from the ends 2a and 3a of the mold 2 and the molding material 3, the sheet-shaped molding material 3 is damaged. The product value of the molded product is reduced.

そこで、本発明は、上記課題に鑑み、真空成形を行う際に、成形素材を成形型に確実に固定し、成形素材に傷を付けない成形素材固定具を提供することを目的とする。   In view of the above problems, an object of the present invention is to provide a molding material fixture that securely fixes a molding material to a molding die and does not damage the molding material when performing vacuum molding.

Specifically, the insert panel 11 is formed, for example, by bending a single metal plate approximately 90 degrees at both ends of the intermediate portion 11c so that the upper portion 11a and the lower portion 11b face each other.
The covering portion 12 is formed by covering the upper portion 11a, the lower portion 11b, and the intermediate portion 11c with a soft material. Here, the groove 13 is formed by the first contact portion 12a covering the lower side of the upper portion 11a around the upper portion 11a and the second contact portion 12b covering the upper side of the lower portion 11b around the lower portion 11b. That is, the first contact portion 12a and the second contact portion 12b are disposed to face each other with a gap therebetween, thereby forming the groove 13. When the end 2a of the mold 2 and the end 3a of the molding material 3 are put into the groove 13, that is, when the molding material fixture 1 sandwiches the ends 2a, 3a, the first contact portion 12a.

In addition to the case where the cavity 14 is provided between the first contact portion 12a and the upper plate 11a, a similar cavity may be provided between the second contact portion 12b and the lower plate 11b.

さらには、第１接触部１２ａには、第２接触部１２ｂ側に、複数の第１突起１２ｃが一様に設けられている。すなわち、第１接触部１２ａには、溝１３の深さ方向に複数列、該深さ方向に垂直な方向に複数行、第１突起１２ｃが設けられている。第１突起１２ｃは、波型形状であることが好ましい。すなわち、成形素材固定具１が成形型２および成形素材３の各端部２ａ，３ａを合わせた状態で各端部２ａ，３ａを挟んだ際に、成形素材３の端部３ａと平行になるように第１突起１２ｃが傾斜していることが好ましい。
また、第２接触部１２ｂには、第１接触部１２ａ側に、複数の第２突起１２ｄが一様に設けられている。すなわち、第２接触部１２ｂには、溝１３の深さ方向に複数列、該深さ方向に垂直な方向に複数行、第２突起１２ｄが設けられている。第２突起１２ｄは、四角錐などの略角錐形状であることが好ましいが、他の形状であってもよい。 Further, the first contact portion 12a is provided with a plurality of first protrusions 12c uniformly on the second contact portion 12b side.

The second protrusion 12d is preferably in a substantially pyramid shape such as a quadrangular pyramid, but may have another shape.

以上のように構成された成形素材固定具１の使用形態について次に説明する。
図４（Ａ）〜（Ｄ）は、成形素材固定具１が成形型２および成形素材３の各端部２ａ，３ａを挟んで、成形素材３を成形する一連の工程を示した概略図である。
先ず、図４（Ａ）に示すように、成形型２の型面にシート状の成形素材３を被せて、成形型２の端部２ａに成形素材３の端部３ａを重ね合わせる。 Next, the usage form of the molding material fixture 1 configured as described above will be described.
4A to 4D are schematic views showing a series of steps in which the molding material fixture 1 molds the molding material 3 by sandwiching the end portions 2a and 3a of the molding die 2 and the molding material 3. is there.
First, as shown in FIG. 4A, the sheet surface of the molding die 2 is covered with the sheet-like molding material 3, and the end portion 3 a of the molding material 3 is overlapped with the end portion 2 a of the molding die 2.

次に、図４（Ｂ）に示すように、成形型２の端部２ａおよび成形素材３の端部３ａに成形素材固定具１を装着する。すなわち、成形素材固定具１の溝１３に成形型２の端部２ａおよび成形素材３の端部３ａを入れることになる。そのとき、軟質材で成形された被覆部１２のうち、溝１３を形成している第１接触部１２ａの第１突起１２ｃが倒されて成形素材３の表面に平行になりつつ、空洞１４が矢印で示すように潰される。   Next, as shown in FIG. 4B, the molding material fixture 1 is attached to the end 2 a of the molding die 2 and the end 3 a of the molding material 3. That is, the end 2 a of the mold 2 and the end 3 a of the molding material 3 are put into the groove 13 of the molding material fixture 1. At that time, the first protrusion 12c of the first contact portion 12a forming the groove 13 of the covering portion 12 formed of a soft material is tilted and becomes parallel to the surface of the molding material 3, while the cavity 14 is formed. It is crushed as shown by the arrow.

そして、成形素材固定具１で成形素材３が成形型２の端部２ａに固定された状態で、軟質材などで真空排気可能な領域を形成した真空パック４内に、成形型２および成形素材３を収納する。そして、図４（Ｃ）に示すように、真空排気可能な領域を形成する真空パック４の吸引口４ａから図の矢印で示した方向に吸引して、真空パック４内を真空排気するとともに、図示しない加熱手段で成形素材３を熱変形温度まで加熱する。
図５は図４（Ｃ）に示した工程での成形素材固定具１の部分斜視図である。真空パック４内が真空排気されて減圧されるため、成形素材固定具１の被覆部１２内に形成された空洞１４が、図４（Ｃ）に矢印で示すように膨張する。これにより、被覆部１２の第１接触部１２ａが、成形素材３の端部３ａを押圧する。従って、成形素材固定具１で、成形型２の端部２ａに対する成形素材３の端部３ａの位置ズレをさらに防止することができる。
また、図４（Ｃ）に示すように、成形素材３は成形型２の型面に押し当てられて密着するので、成形素材３が型面の形状に成形される。 Then, in a state where the molding material 3 is fixed to the end 2a of the molding die 2 with the molding material fixture 1, the molding die 2 and the molding material are formed in a vacuum pack 4 in which a region that can be evacuated with a soft material or the like is formed. 3 is stored. And as shown in FIG.4 (C), while sucking in the direction shown by the arrow of the figure from the suction opening 4a of the vacuum pack 4 which forms the area | region which can be evacuated, while evacuating the inside of the vacuum pack 4, The molding material 3 is heated to a heat deformation temperature by a heating means (not shown).
FIG. 5 is a partial perspective view of the molding material fixture 1 in the step shown in FIG. Since the inside of the vacuum pack 4 is evacuated and depressurized, the cavity 14 formed in the covering portion 12 of the molding material fixture 1 expands as shown by an arrow in FIG. Thereby, the first contact portion 12 a of the covering portion 12 presses the end portion 3 a of the molding material 3. Therefore, it is possible to further prevent the positional deviation of the end portion 3 a of the molding material 3 with respect to the end portion 2 a of the molding die 2 with the molding material fixture 1.
As shown in FIG. 4C, the molding material 3 is pressed against and closely adhered to the mold surface of the molding die 2, so that the molding material 3 is molded into the shape of the mold surface.

最後に、成形型２に成形素材３が密着した状態でかつ端部２ａ，３ａが成形素材固定具１に挟まれた状態で真空パック４から取り出し、図４（Ｄ）に示すように、成形素材固定具１を端部２ａ，３ａから取り外した後に成形素材３を成形型２から外す。このとき、成形素材固定具１の周りは減圧状態から大気圧状態になっているので、成形素材固定具１の空洞１４の膨らみは、もとの状態、つまり図４（Ｂ）の工程での膨らみと同程度になっている。従って、成形素材固定具１を端部２ａ，３ａから容易に取り外すことができる。   Finally, the molding material 3 is in close contact with the molding die 2 and the ends 2a and 3a are sandwiched between the molding material fixtures 1 and taken out from the vacuum pack 4, and as shown in FIG. After the material fixture 1 is removed from the end portions 2 a and 3 a, the molding material 3 is removed from the molding die 2. At this time, since the periphery of the molding material fixture 1 is changed from the reduced pressure state to the atmospheric pressure state, the swelling of the cavity 14 of the molding material fixture 1 is in the original state, that is, in the process of FIG. It is about the same as the bulge. Therefore, the molding material fixture 1 can be easily detached from the end portions 2a and 3a.

以上説明したように、重なり合う成形型２の端部２ａと成形素材３の端部３ａとを成形素材固定具１で挟んで、成形素材固定具１を装着した後に、成形型２および成形素材３とともに真空排気可能な領域内に収納して真空排気することで、被覆部１２内の空洞１４が膨張する。よって、被覆部１２の第１接触部１２ａが成形素材３の端部３ａを押圧するので、成形素材３を成形型２の端部２ａに確実に固定することができ、成形素材３と成形型２との位置ズレを防止することができる。
また、成形素材固定具１は真空排気可能な領域内に収納した状態で加熱されるので、シリコンゴム等の耐熱性の軟質材で成形されるが、別に他の軟質材で成形してもよい。 As described above, after the end 2a of the mold 2 and the end 3a of the molding material 3 are sandwiched between the molding material fixture 1 and the molding material fixture 1 is mounted, the molding die 2 and the molding material 3 are attached. At the same time, the cavity 14 in the covering portion 12 expands by being housed in a region that can be evacuated and evacuated. Therefore, since the first contact portion 12a of the covering portion 12 presses the end portion 3a of the molding material 3, the molding material 3 can be reliably fixed to the end portion 2a of the molding die 2, and the molding material 3 and the molding die can be fixed. 2 can be prevented from being displaced.
In addition, since the molding material fixture 1 is heated in a state where it is housed in an area that can be evacuated, it is molded from a heat-resistant soft material such as silicon rubber, but may be molded from another soft material. .

以上説明した本発明を実施するための最良の形態は、本発明を具体化する場合の一例であって、特許請求の範囲に記載した発明の範囲内で種々変更が可能である。
例えば、第１接触部１２ａに設けられる第１突起１２ｃや第２接触部１２ｂに設けられる第２突起１２ｄは、波型形状や、角錐形状に限らず、それぞれ他の形状でもよい。 The best mode for carrying out the present invention described above is an example when the present invention is embodied, and various modifications can be made within the scope of the invention described in the claims.
For example, the first protrusion 12c provided on the first contact portion 12a and the second protrusion 12d provided on the second contact portion 12b are not limited to the corrugated shape or the pyramid shape, and may have other shapes.
