  As a conventional method for manufacturing an interior material, for example, a method described in Patent Document 1 is known. In this interior material manufacturing method, first, a base material having a convex shape is arranged on the upper surface of the cradle, and a skin material is further arranged above the base material, and the skin material is pressed against the base material. A support body composed of the elastic film and a support plate for supporting the end of the elastic film is disposed so as to face the skin material.

  Next, by inflating the elastic membrane and bringing the support close to the cradle, the skin material pushed downward by the elastic membrane is pressed against the surface of the base material, and the skin material and the base material are attached. Interior materials are provided.

Japanese Patent Laid-Open No. 1-195021

  In the said patent document 1, a skin material is stuck on the surface of the base material which has a convex shape. However, when the method described in Patent Document 1 is applied to a concave base material, the base end of the concave portion of the base material comes into contact with the skin material before the bottom surface of the concave portion of the base material. For this reason, the skin material may be caught on the base end portion of the base material, and the skin material may not reach the concave portion of the base material. As a result, a float may be generated between the base material and the skin material.

  In addition, when the method of Patent Document 1 is applied to a substrate having a concave shape in a state in which the skin material is slackened in advance so as not to cause a float between the base material and the skin material, Since the material is pasted in a slack state, the skin material may be wrinkled.

  The present invention has been made in view of the above circumstances, and in an interior material manufacturing method in which a skin material is pasted on a concave inner surface of a concave base material, the float floats between the base material and the skin material. The purpose is to prevent or suppress the occurrence of wrinkles and wrinkles on the skin material.

  In order to solve the above-described problem, the method for producing an interior material according to the present invention is a method for producing an interior material having a configuration in which a skin material is attached to the concave inner surface of a substrate having a concave shape, A base support mold that supports the mold, a mold surface that is deformable along the surface of the base support mold that is the opposing member, and a part of the mold surface that protrudes from the base support mold side. And using a skin material support mold capable of supporting the skin material on the mold surface, and making the base material support mold and the skin material support mold relatively close to each other. In the step of sticking the skin material to the base material, the step of partially projecting the mold surface toward the base material support mold side by the mold surface variable member of the skin material support mold, The skin material supported on the mold surface is applied to the concave bottom surface of the base material. And the step of bringing the skin material into contact with the concave inner surface of the base material by deforming the mold surface along the concave shape of the base material after the tip contact, and the contact And a step of attaching the skin material to the base material.

  According to this method, when the base material support mold and the skin material support mold are close to each other and the mold is closed, the skin material is made to contact the concave bottom surface of the base material first. It is affixed in order from the first contacted part to the outside.

  For this reason, the skin material is attached to the entire concave inner surface of the base material following the shape of the base material, so that it is possible to prevent or suppress the floating between the skin material and the base material. Moreover, in this method, since it is not necessary to sag the skin material in advance to prevent the occurrence of floating between the base material and the skin material as described above, the skin material is not stuck in a loose state. Moreover, wrinkles can be prevented from occurring in the skin material.

  As an embodiment of the present invention, in the step of bringing the skin material into contact with the concave inner surface of the base material, the mold surface variable member is moved as the base material support die approaches the skin material support die. It is preferable to retract.

  According to the above configuration, in the step of bringing the skin material into contact with the concave inner surface of the base material, when the base material support die and the skin material support die are close to each other, by the die surface variable member The top surface of the mold surface that protrudes toward the base material support mold side retreats while pressing the skin material against the base material in conjunction with the proximity of the base material support mold and the skin material support mold. In this state, the part of the skin material that is first bonded to the base material is kept pressed. For this reason, the skin material that has first contacted and adhered to the concave bottom surface of the base material can be prevented from peeling off from the base material.

  An embodiment of a method for manufacturing an interior material according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a door trim 50 to which a decorating member 10 corresponding to an interior material provided by the manufacturing method of the present embodiment is attached. The door trim 50 is provided with an inside handle 31 above, a speaker grill 32 below, an arm rest 33 behind the inside handle 31, and an ornament 34 above the arm rest 33.

  And the decoration member 10 provided by this embodiment is the one in which the armrest part 33 and the ornament part 34 are integrated, and the skin material 12 is affixed on the base material 11 as shown in FIG. It has a configuration. The substrate 11 is made of a fiber impregnated with a synthetic resin, has a substantially L-shaped cross section, and has a concave inner surface 11A. The skin material 12 is affixed to the surface of the base material 11 in order to improve the designability of the base material 11. As the skin material 12, a synthetic resin sheet, woven fabric, non-woven fabric, leather, or the like can be used.

The manufacturing method of such a decorative member 10 is as follows.
First, as an apparatus used for the production, an apparatus including a pair of molds 21 and 22 is adopted as shown in FIG. The mold 21 is configured as a substrate support mold that can support the substrate 11 (hereinafter referred to as a substrate support mold 21). On the other hand, the mold 22 is configured as a skin material support mold capable of supporting the skin material 12 (hereinafter referred to as a skin material support mold 22).

  The base material support die 21 includes a main body portion 13 that mainly constitutes the die, a base material placement portion 13A that constitutes a surface of the die and places the base material 11, and a base material attaching / detaching portion 13B. ,have.

13 A of base material arrangement | positioning parts have the concave shape similar to the base material 11, and are connected with the base material attachment / detachment part 13B.
The base material attaching / detaching part 13B penetrates the inside of the base material supporting mold 13 from the base material arranging part 13A and communicates with the outside of the base material supporting mold 13 and arranges the base material 11 by sucking or jetting air. This is intended to be detachable from the part 13A.

The skin material support die 22 has a main body portion 15 that mainly constitutes the die, and a skin material arrangement portion 14 that constitutes the surface of the die and is a portion for arranging the skin material 12.
The skin material placement portion 14 is made of an elastic film that can be elastically deformed, and can be deformed along the surface shape of the base material support die 21 that is the counterpart mold (hereinafter, the skin material placement portion 14 is referred to as a mold surface 14). ).

  On the other hand, the main body 15 includes a mold surface fixing jig 18 for fixing the mold surface 14, and includes a concave groove 20 in order to form a space 19 on the back side of the fixed mold surface 14. . The mold surface fixing jig 18 fixes the mold surface 14 to the main body 15 by sandwiching the end of the mold surface 14 made of an elastic film.

  The skin material support die 22 is formed with a fluid movement passage 17 that leads from the outside of the skin material support die 22 to a space 19 in a region surrounded by the die surface 14 and the main body 15. The fluid movement passage 17 is a passage for flowing in fluid, for example air, from a fluid injection / suction device (not shown) outside the skin material support die 22. Then, as the air is fed into the fluid moving passage 17 by using the fluid injection / suction device, the space 19 is filled with air, and the mold surface 14 can bulge upward. Yes.

  Further, the surface material support die 22 is formed with a die surface variable member 16 that partially protrudes the die surface 14 with respect to the base material support die 21 side. The mold surface variable member 16 is composed of, for example, a pneumatic piston, and is disposed between the skin material support mold 15 and the mold surface 14, that is, in the space 19. The tip portion of the mold surface variable member 16 can be moved up and down, and the mold surface 14 can be partially projected by moving the tip portion of the mold surface variable member 16 upward.

Next, the manufacturing procedure of the decorating member 10 using the base material support die 21 and the skin material support die 22 will be shown.
As shown in FIG. 3, first, the base material 11 is placed on the base material placement portion 13A. Note that an adhesive is applied to the concave inner surface 11 </ b> A of the substrate 11. Next, the base material 11 is supported on the base material support die 21 by the suction action of the base material attaching / detaching portion 13B.
On the other hand, in the skin material support mold 22, the skin material 12 is disposed on the upper surface of the mold surface 14 facing the base material support mold 21.

(Step of partially projecting the mold surface 14 toward the substrate support mold 21)
Next, the tip of the mold surface variable member 16 is raised. Then, the mold surface 14 that is in contact with the mold surface variable member 16 can be protruded toward the substrate support mold 21 side so-called upward. At this time, the skin material 12 also has a shape projecting upward in accordance with the shape of the mold surface 14.

(Step of causing the skin material 12 to contact the concave bottom surface of the base material 11 first)
Next, as shown in FIG. 4, the base material support die 21 is lowered or the skin material support die 22 is raised to bring both dies closer. When this approach reaches a predetermined distance, the topmost portion of the skin material 12 protruding upward comes first to the concave bottom surface of the base material 11.

(Step of bringing the skin material 12 into contact with the concave inner surface 11A of the base material 11)
Thereafter, as shown in FIG. 4, the base material support die 21 is moved down or the skin material support die 22 is raised, so that the base material support die 21 is brought close to the skin material support die 22 and the mold is closed. At this time, the mold surface variable member 16 is lowered at a speed substantially equal to the lowering speed of the base material support mold 21 or the rising speed of the skin material support mold 22.

  In this way, by lowering the mold surface variable member 16 at a speed substantially the same as the speed at which the base material support mold 21 is lowered or the skin material support mold 22 is lifted, the part of the skin material 12 that has come first to the base material 11 Is maintained between the mold surface variable member 16 and the base material support mold 21. For this reason, the skin material 12 that has contacted and adhered to the concave bottom surface of the base material 11 can be prevented from being peeled off from the base material 11.

  Further, since the skin material 12 is brought into contact with the concave bottom surface of the base material 11 in the previous process, the base material support die 21 and the skin material support die 22 are brought close to each other, so that the skin material 12 becomes the base material. The material 11 is successively brought into contact with the material 11 from the concave bottom surface that comes into contact with the material 11. Therefore, when the base material support die 21 and the skin material support die 22 are closed, the skin material 12 is brought into contact with the entire concave inner surface 11A of the base material 11 following the shape of the base material 11. It is possible to prevent floating between the skin material 22 and the base material 21.

  Furthermore, in the method of the present embodiment, for example, there is no need to sag the skin material 12 in advance in order to prevent floating between the base material 11 and the skin material 12, so that the skin material is loosened. It is possible to prevent the skin material 12 from being wrinkled.

(Step of attaching the skin material 12 to the base material 11)
Next, air is sent from the fluid injection / suction device to the fluid movement passage 17 to fill the space 19 with air. By filling the space 19 with air, the mold surface 14 swells upward. However, since the base material support die 21 and the skin material support die 22 are in a closed state, the die surface 14 follows the concave inner surface 11A of the base material 11 supported in the base material support die 21. Swell. Therefore, since the skin material 12 that is in contact with the entire concave inner surface 11A of the base material 11 is pressed against the base material 11 by the mold surface 14, the base material 11 and the skin material 12 can be firmly attached. .

  Then, the decorating member 10 by which the skin material 12 was mounted | worn by the concave inner surface can be obtained by removing the decorating member 10 from the base-material support type | mold 13.

  In the manufacturing method of the present embodiment as described above, the mold surface variable member 16 is disposed in the space 19 of the skin material support mold 22, and the tip of the mold surface variable member 16 is raised to partially cover the skin material 12. After projecting, the projecting portion is brought into contact with the concave bottom surface of the base material 11, and the skin material 12 is brought into contact with the entire concave inner surface 11 </ b> A of the base material 11, thereby attaching the skin material 12 to the base material 11. Therefore, it is possible to prevent floating between the base material 11 and the skin material 12. Further, since it is not necessary to consider a measure for preventing floating, wrinkles can be prevented from occurring in the skin material 12.

  Further, when the base material support die 21 is lowered or the skin material support die 22 is raised to close the die, the die surface variable member 16 is retracted at substantially the same speed as the lowering speed of the base material support die 21. The skin material 12 that comes into contact with and adheres to the concave bottom surface of the base material 11 can be prevented from peeling off from the base material 11.
