本発明は真空成形用型に関し、より詳しくは表皮材の縁
部を芯材の裏面に接合するための真空成形用型に関する
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vacuum forming mold, and more particularly to a vacuum forming mold for joining the edge of a skin material to the back surface of a core material.

の裏面へ接着する方法が提案されている。Instrument panel pads, which are automobile interior parts,
Door trims, etc. or various types of furniture are made of a foam layer laminated on a core material, and a skin material covering the foam layer, and the ends of this skin material are wrapped around the back side of the core material,
It consists of a structure in which the folding margin is glued together. However, in this type of manufacturing method, it takes time and effort to set each member of the core material 2 foam and the skin material. Therefore, as a solution to this problem, a composite skin material made of a skin material such as vinyl chloride or ABS resin laminated with a foam material such as polyurethane foam is adhered to the inner surface of a lower mold for vacuum forming which is equipped with a plurality of suction holes. A method has been proposed in which the end portion of the composite skin is adhered to the back surface of the core.
しかし、この場合巻き込みしろとなる複合表皮体の末端

のため、巻き込みしろとなる複合表皮体の末端部の長さ
は必然的に短縮され、このため表皮体の末端部分と芯体
との接着領域は縮小し、その接着力は小さくなり剥離し
やすくなるなどの欠点かあった。However, in this case, the end of the composite skin body, which is the margin for wrapping, is left in a free state, so when the upper mold is combined with the lower mold, this end may hang downward, and the core is not completely centered. When I turned it around to the back side of the material, this end often ended up joining in unexpected places. As a result, the length of the end of the composite skin, which provides room for wrapping, is inevitably shortened, and as a result, the adhesive area between the end of the skin and the core is reduced, and the adhesive force is reduced, making it easier to peel off. There were some drawbacks, such as:
本発明はこのような点を改善し、表皮材の末端部を芯材

面方向に摺動可能にした真空成形用型にある。The present invention improves these points and provides a vacuum forming mold that can accurately adhere the end portion of the skin material to the back surface of the core material.The present invention is characterized by the vacuum suction in the lower mold. A hollow part for the mold is placed separately at the lower part of the one-step taller flange surface provided around the lower mold periphery and at the lower part of the inner surface of the mold located at the center where the skin material is adsorbed, and on the flange surface. An upper mold holder is provided that is open toward the inner surface of the mold, and a bushing block whose tip end is a bias surface and whose upper end is an acute-angled apex is installed in the space formed between the flange surface and the upper mold holder. The present invention provides a vacuum forming mold in which the bushing block is slidable on the flange surface toward the inner surface of the mold.

吸着して完全な型付けが進行する。Next, to explain the effects of the vacuum forming mold according to the present invention, first, a composite skin material (α6) made of a skin material α6) made of vinyl chloride, ABS resin, etc. and a foam material α6) such as polyurethane foam is laminated in advance. ) is heated and softened, and the composite skin material α8) is completely covered with the pull-shaped inner surface (3) of the composite skin material α8).
is set on the lower mold (1) so that its peripheral edge extends onto the flange surface (2), more specifically on the upper mold holding table α℃, and then each bushing block (2) is placed on the inner surface of the mold (3). ) direction, press the bias surface of block Oa (9)
The obtuse lower end (9) of the flange surface (2) is aligned with the inner edge of the flange surface (2). Then, the flange side cavity (4) and mold inner side cavity (5) are both evacuated to form a composite skin material (see FIG. 3). In this case, the push block αa maintains the advanced state, and the flange surface (2)
Since the cavity (4) is also degassed, the composite skin material α8)
is adsorbed onto the surfaces of the upper mold holding table αB and the pusher block 03, and complete molding progresses.

Cut the material α8) and perform skin trim (4th
(see figure). Therefore, the remaining composite skin material α8) is more efficiently adsorbed to the mold inner surface by degassing only the mold inner cavity (5).

) is degassed, and the push block Q31 is moved back to the opposite side, and then the upper mold 09 is assembled. In the skin molding process shown in Fig. 3, the free end is molded to be tilted inward of the skin molded body, so even if it comes into contact with the inner surface of the upper mold 09), it will not sag any further. . Then, a hard polyurethane foam that will become the core material (a) is cast, cured, and then removed from the mold. Obtained molded product ■D
As illustrated in FIG. 6, the end portion of the composite skin material α8) is completely and beautifully joined to the back surface of the core material (A).

確、美麗にかつ迅速に行うことができる。In the vacuum forming mold of the present invention, the cavity is separated into the flange surface cavity and the mold inner cavity, so the composite skin material on the part that will become the product surface can be efficiently removed from the mold inner surface by degassing the mold inner cavity. In addition, the tip of the flange surface is a bias surface, and a slidable bushing block with an acute angled apex at the upper end is arranged. Since the end edge can be molded in a state where it is tilted toward the main body, the end edge of the composite skin material can elastically come into close contact with the inner surface of the upper mold, which allows the skin material to be attached to the back side of the cast core material. The distal edges of the can be joined accurately, beautifully, and quickly.
