  Embodiments will be described with reference to the drawings. FIG. 1 is a flowchart showing a method for manufacturing the substrate K shown in FIG. As shown in FIG. 1, in order to manufacture the base material K, after heating the whole plate-shaped body W which consists of the material which mixed the vegetable fiber and the thermoplastic resin (preheating process), The heat storage state is maintained (main heating step), the stored plate-like body W is preformed into a preformed body Z (preliminary molding step), and the preformed body Z is subjected to main molding onto the base material K (main molding step). Thereby, the base material K shape | molded by the predetermined shape can be obtained.

The vegetable fiber contained in the plate-like body W is a plant-derived fiber material. Such a fiber material can be collected from, for example, cotton, hemp, sisal, jute, kenaf and the like. Of these, kenaf is particularly preferred. This is because kenaf is effective for global environmental conservation because it grows quickly and absorbs a lot of CO ₂ . Also, it is possible to collect relatively long and strong fibers from kenaf bast.

  As the thermoplastic resin contained in the plate-like body W, for example, polyethylene (PE), polypropylene (PP), polylactic acid (PLA), or the like can be used. Among these, polypropylene is particularly preferable.

  In order to manufacture the plate-like body W, after making it into a mat shape by blending the material which mixed the vegetable fiber and the thermoplastic resin, the obtained mat body is shape | molded in a plate shape with a hot press. Thereby, the plate-shaped body W which has predetermined | prescribed thickness can be manufactured. Such a manufacturing method of the plate-like body W is disclosed in, for example, Japanese Patent Application Laid-Open Nos. 2001-179716 and 2002-371455. In addition, the plate-like body W may be referred to by another name such as “fiberboard for thermoforming” or “preboard”.

  By heating the plate-like body W, the thermoplastic resin contained in the plate-like body W can be melted. For example, when the thermoplastic resin contained in the plate-like body W is polypropylene, since the melting point of polypropylene is 160 ° C. to 170 ° C., the plate-like body W is heated to a temperature higher than this (for example, 200 ° C.). Thus, the thermoplastic resin contained in the plate-like body W can be melted.

  2 and 3 are cross-sectional views of a preforming mold 10 for preforming the plate-like body W. FIG. As shown in FIG. 2, the preforming mold 10 has a pair of molds 12 and 14. Among these, one metal mold | die 12 has the shape where the center part was dented, and the other metal mold | die 14 has the shape where the center part protruded. The pair of molds 12 and 14 are arranged in the horizontal direction (left and right directions in FIGS. 2 and 3) so that the mold surfaces face each other. Then, the plate-like body W is disposed between the mold surfaces of the molds 12 and 14 in a state of being suspended in a direction perpendicular to the mold closing direction of the molds 12 and 14 (vertical direction in FIGS. 2 and 3). The As shown in FIG. 3, the pair of molds 12 and 14 constituting the preforming mold 10 is suspended in the vertical direction by moving the mold 12 toward the mold 14 and closing the mold, for example. The plate-like body W can be pressed from both the front and back sides. Thereby, the plate-like body W is shape | molded by the preforming body W1.

  4, 5, and 6 are cross-sectional views of the main mold 20 for main molding the plate-like body W. FIG. As shown in FIG. 4, the main mold 20 has a pair of molds 22 and 24. Among these, one metal mold | die 22 has a shape where the center part was dented, and the other metal mold | die 24 has the shape where the center part protruded. The pair of molds 22 and 24 are arranged in the horizontal direction (left and right direction in the figure) so that the mold surfaces 22a and 24a face each other. In FIG. 4, the position of the preform W1 disposed at the center of both mold surfaces 22a and 24a is hereinafter referred to as “set center”.

  As shown in FIG. 5, the preform W <b> 1 is arranged in advance on the mold surface 24 a side (molding center side) of the other mold 24 prior to the press work performed by both the molds 22 and 24. Next, as shown in FIG. 6, the pair of molds 22 and 24 constituting the main mold 20 are suspended in the vertical direction by moving the mold 22 toward the mold 24 and closing the mold, for example. It is possible to press the plate W in a state from both the front and back sides.

  As the main mold 20 for main molding the preform W1, a cold press mold is used. The “cold press” here means press molding performed without actively heating the mold surface of the main mold 20, but the mold surface 22a of the main mold 20 by processing heat, frictional heat or the like. 24a is heated to some extent. By pressing the heated preform W1 with the main mold 20 (cold press mold), the thermoplastic resin contained in the preform W1 is cooled and solidified. Thereby, the base material K shape | molded by the predetermined shape can be obtained (refer FIG. 6). In FIG. 6, the position of the base material K arranged at the center of both mold surfaces 22 a and 24 a is hereinafter referred to as “molding center”.

  The base material K thus obtained is lightweight and high in strength, and therefore can be used as a base material for vehicle interior materials. For example, the base material K can be used for door trims, instrument panels, seat back boards, partition boards, console boxes, pillar garnishes, quarter trims, and the like.

  As can be seen from a comparison between FIG. 2 and FIG. 4, the clearance CL <b> 1 of the pair of molds 12 and 14 constituting the preforming mold 10 is larger than the clearance CL <b> 2 of the pair of molds 22 and 24 constituting the main mold 20. Is also set larger. For example, when CL2 is 5 mm, the clearance CL1 is set to 10 mm, which is larger than that. Therefore, instead of forming the plate-like body W into the base material K at a time, first, the plate-like body W is formed into the preformed body W1, and then the preformed body W1 is formed into the base material K. Thus, it is possible to form in steps (in two steps).

  Further, the preform W1 introduced to the center of the set in the main molding step is moved to the center of the molding to perform the main molding, so that the preform W1 is placed on the mold surface while the molds 22 and 24 are being closed. It is possible to avoid being caught by a part and to restrict the central part of the base material K from being stretched by a part of the mold surface after press working to become thin.

  Next, the configuration of the hanger 30 that holds the plate-like body W will be described. FIG. 7 is a perspective view of the hanger 30 for holding the plate-like body W in a suspended state. FIG. 8 is a side view of the hanger 30.

In addition, the clamp 34 and the roller 36 are positioned substantially coaxially with respect to the shaft 32 in the vertical direction.

  As shown in FIG. 8, the clamp 34 has a pair of clamping members made of a metal plate member such as iron or aluminum. Both clamping members are composed of a movable plate 34a and a fixed plate 34b, and a hinge 35 is attached between the movable plate 34a and the fixed plate 34b. It is comprised so that can be pinched | interposed. That is, one of the holding members can be opened and closed between a closed position for holding the upper edge of the plate-like body W and an open position for releasing the upper edge of the plate-like body W with respect to the other. Yes. A spring member 37 is attached between the upper end portions of the movable plate 34a and the fixed plate 34b, and the lower end portion of the movable plate 34a is urged by the spring member 37 in the closing direction with the hinge 35 as a fulcrum.
