Forms a flush molding surface.

According to the above configuration, even if the adhesive comes into contact with the resin part during crimping, the non-adhesive nature of the resin part suppresses the adhesion of the adhesive and makes it possible to easily peel off the adhered adhesive. . By providing the resin part embedded in the mold, there is no need to repeatedly perform processes such as coating with a mold release agent, and deterioration of workability can be prevented.

Moreover, the mold for the interior material of the present invention may be further configured as follows. The resin part is removably fixed to the male mold and/or female mold in which the resin part is provided by bolting from a direction crossing the mold clamping direction. According to the above configuration, the resin part can be removed from the male mold and/or the female mold and easily replaced. Thereby, the maintainability of the mold can be further improved. Further, by tightening the bolts from a direction intersecting the mold clamping direction, the bolts can be prevented from interfering with the clamping of the mold.

Moreover, the mold for the interior material of the present invention may be further configured as follows. The resin part is arranged so as to extend endlessly along the end of the skin material with respect to the male mold and/or the female mold in which the resin part is provided. According to the above configuration, the resin part can apply pressure bonding force by mold clamping to the entire circumference of the end of the skin material.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A mode for carrying out the present invention will be described below with reference to FIGS. 1-12. In the following description, when directions such as front, back, top, bottom, left, and right are indicated, the respective directions shown in each figure are referred to.

<First embodiment>
First, a mold (mold 1) for an interior material according to a first embodiment of the present invention will be described. A mold 1 according to this embodiment is a mold for molding an interior material 2 for an automobile (see FIG. 2). As shown in FIG. 1, the mold 1 includes an upper mold 11 and a lower mold 12 made of metal. As shown in FIG. 4, the base material 21 of the interior material 2 is set on the upper mold 11. Further, the skin material 22 of the interior material 2 is set on the lower mold 12. The upper mold 11 and the lower mold 12 are clamped so as to sandwich the base material 21 and the skin material 22 set therein. As a result, as shown in FIGS. 4-7, the upper mold 11 and the lower mold 12 press the base material 21 and the skin material 22 together to form the interior material 2.

Further, the upper mold 11 has a recessed portion 11b that is recessed relative to the molding surface portion 11a of the upper mold 11, as shown in FIG. The recessed portion 11b is formed at the periphery of the upper die 11. A solid resin portion 13 made of a non-adhesive fluororesin such as Teflon (registered trademark) is embedded in the recess 11b.

As shown in FIG. 2, an adhesive 23 is applied between the base material 21 and the skin material 22 over the entire surface where they are overlapped with each other. The base material 21 and the skin material 22, which are clamped to the upper mold 11 and the lower mold 12, are integrally attached to each other by the adhesive 23. The adhesive 23 may leak out from the ends of the base material 21 and/or the skin material 22 due to mold clamping. As a result, the leaked adhesive 23 comes into contact with the peripheral edge of the upper die 11.

However, the above-mentioned resin portion 13 is provided on the peripheral edge of the upper mold 11. Since the resin part 13 has non-adhesive properties, the adhesive 23 is less likely to adhere thereto than to the molding surface part 11a of the upper mold 11 made of a metal material. Therefore, the resin portion 13 can suppress adhesion of the adhesive 23 to the upper mold 11. Furthermore, even if the adhesive 23 adheres to the resin part 13, the adhesive 23 can be easily peeled off from the resin part 13.

Furthermore, since the resin portion 13 is a solid member, it has higher rigidity and durability than tapes or coatings that have the same non-adhesive properties. Thereby, damage and deformation of the resin part 13 can be suppressed when the mold 1 is repeatedly used. Therefore, the maintainability of the mold 1 can be improved by the resin portion 13.

<Mold 1>
Hereinafter, each structure of the mold 1 and interior material 2 will be explained in detail. As shown in FIG. 1, the mold 1 is configured to be clamped such that a convex upper mold 11 is fitted into a concave lower mold 12. The upper mold 11 has a molding surface portion 11a formed to match the shape of the back surface of the base material 21, as shown in FIGS. 1 and 4. The lower mold 12 has a molding surface portion 12 a formed to match the shape of the surface of the base material 21 . Here, the upper mold 11 corresponds to the "male mold" of the present invention. Further, the lower mold 12 corresponds to the "female mold" of the present invention.

The resin portion 13 is not provided at the center of the upper mold 11 but is provided only at the peripheral portion of the upper mold 11. Specifically, when the upper mold 11 is clamped to the lower mold 12, the resin part 13 is arranged so as to extend in a frame shape along the peripheral edge of the upper mold 11 that faces the peripheral edge of the base material 21. be done. Further, the resin portion 13 has a molding surface 13a that is substantially flush with the molding surface portion 11a of the upper mold 11. The molding surface 13a is formed to match the shape of the peripheral edge of the base material 21.

With the above configuration, the molding surface portion 11a made of a metal material of the upper mold 11 sandwiches the general surfaces of the base material 21 and the skin material 22 with the lower mold 12 to apply a pressing force. Further, the resin portion 13 sandwiches the peripheral edge of the base material 21 and the end of the skin material 22 between it and the lower mold 12 to apply a pressure bonding force. As a result, the molding surface portion 11a can apply strong pressure to the general surfaces of the base material 21 and the skin material 22 between the molding surface portion 11a and the lower mold 12. Therefore, when transferring a design shape such as a grain onto the surface of a skin material, it is possible to appropriately press the material. Further, the resin portion 13 can appropriately suppress adhesion of the adhesive 23 to the peripheral edge of the upper die 11 with which the adhesive 23 easily comes into contact. In this way, the mold 1 can appropriately achieve both pressure bonding by strong pressure force and suppression of adhesion of the adhesive 23.

<Interior material 2>
As shown in FIGS. 2 and 3, the interior material 2 includes a base material 21 forming the basic shape of the interior material 2, a skin material 22 forming the design surface of the interior material 2, and the adhesive 23. The base material 21 is made of resin such as PP by injection molding. The base material 21 has a predetermined three-dimensional shape. As the adhesive 23, for example, chloroprene adhesive or hot melt is used.

As shown in FIG. 2, the skin material 22 is placed over the surface of the base material 21 (lower surface side in the figure). Further, the skin material 22 has a rolled-up portion 22c that is rolled up on the back surface (upper surface side in the figure) of the base material 21. The winding portion 22c is set to cover the periphery of the base material 21. Further, as shown in FIG. 3, the skin material 22 has a surface layer 22a made of resin such as TPO and forming a designed surface, and a cushion layer 22b made of slab urethane provided on the back surface of the surface layer 22a.

<Molding procedure of mold 1>
Below, a procedure in which the mold 1 molds the interior material 2 will be explained. First, the adhesive 23 is applied to the base material 21 and the skin material 22, respectively. Specifically, it is applied to the entire front surface and the periphery of the back surface of the base material 21. Further, it is applied to the entire back surface (cushion layer 22b) of the skin material 22.

Next, as shown in FIG. 4, the base material 21 is set on the molding surface portion 11a of the upper mold 11. The base material 21 is set with the surface facing downward. The base material 21 is fitted into the molding surface portion 11a to such an extent that it does not fall downward due to the action of gravity. By setting the base material 21, the adhesive 23 applied to the periphery of the back surface of the base material 21 comes into contact with the upper mold 11. However, the contact area of the adhesive 23 is covered by the resin portion 13. Thereby, the resin part 13 suppresses the adhesion of the adhesive 23 to the upper mold 11.

Next, the skin material 22 is set on the molding surface portion 12a of the lower mold 12. The skin material 22 is set so that the back side faces upward. The skin material 22 is fixed to the lower mold 12 so as not to shift by being evacuated by the lower mold 12.

Next, as shown in FIG. 5, the upper mold 11 is lowered to be clamped to the lower mold 12. Thereby, the base material 21 and the skin material 22 are pressed between the upper mold 11 and the lower mold 12 and are pressed together. Thereby, the front surface of the base material 21 and the back surface of the skin material 22 are adhered to each other by the adhesive 23.

The skin material 22 is formed to be one size larger than the base material 21, as shown in FIG. Therefore, the rolled-up portion 22c of the skin material 22 before being rolled up overhangs the peripheral edge of the base material 21. The resin portion 13 is disposed on a surface wider than the projecting region 22d of the rolled-up portion 22c. Therefore, even if the rolled-up part 22c rises up so as to come into contact with the side surface of the upper die 11, as shown by the imaginary line in FIG. 23 can be appropriately suppressed from adhering to the upper die 11.

After the mold clamping, the upper mold 11 is raised and opened as shown in FIG. The base material 21 is released from the upper mold 11 and held on the lower mold 12 side due to the adhesion force with the skin material 22 held by the lower mold 12 . Next, the winding portion 22c is rolled into the back side of the base material 21 (the top side in the figure). Thereby, the winding part 22c is set so as to cover the peripheral edge of the base material 21.

Next, as shown in FIG. 7, the upper mold 11 is lowered again toward the lower mold 12. Thereby, the resin part 13 sandwiches the rolled-up part 22c and the base material 21 between it and the lower mold 12, and clamps the mold. Thereby, the rolled-up portion 22c is adhered to the back surface of the base material 21 with the adhesive 23. The resin portion 13 is disposed on a wider surface than the wrapping area 22e of the wrapping portion 22c wrapped around the base material 21. Therefore, even if the adhesive 23 protrudes from the end of the rolled-up portion 22c due to mold clamping, the protruding adhesive 23 comes into contact with the resin portion 13. Thereby, the resin part 13 suppresses adhesion of the adhesive 23 to the upper mold 11.

The resin part 13 has lower rigidity than other parts of the upper mold 11 made of metal. Therefore, the resin part 13 is configured to have a relatively weak force to press and sandwich the rolled-up part 22c between the resin part 13 and the lower mold 12. However, the portion pressed between the resin portion 13 and the lower die 12 is configured to have a thicker overall thickness due to the rolled up portion 22c being rolled up. This makes it possible to apply a relatively strong pressure bonding force compared to other parts. In this way, the interior material 2 can be molded by pressing the base material 21 and the skin material 22 together using the mold 1.

<Method for manufacturing upper mold 11>
Below, a method for manufacturing the upper mold 11 in which the resin portion 13 is embedded will be described. First, as shown in FIG. 8, the lower peripheral edge of the upper die 11 made of a rectangular parallelepiped aluminum block is cut into a notch (recess 11b). Next, as shown in FIG. 9, a plurality of pre-divided Teflon (registered trademark) blocks are fitted over the entire circumference of the recess 11b. Each Teflon (registered trademark) block is adhered to the recess 11b using a pasting tool such as adhesive or tape. Thereby, the resin part 13 is formed in a state where it is integrally fixed to the upper mold 11.

Then, as shown in FIG. 10, the upper mold 11 and the resin part 13 are cut to match the shape of the back surface of the base material 21. Thereby, the molding surface portion 11a of the upper mold 11 and the molding surface 13a of the resin portion 13 are formed. The molding surface portion 11a and the molding surface 13a are formed flush with each other. In this way, the upper mold 11 with the resin part 13 embedded therein is manufactured.

Note that, as shown in FIG. 11, the resin part 13 may be removably assembled to the upper mold 11 using bolts 14 and insert nuts 15 (insert nuts). Specifically, the Ensart 15 is embedded in the upper mold 11, the resin part 13 is fitted onto it, and the bolts 14 are fastened to the Ensart 15 from above so as to sandwich the resin part 13. In this way, the resin part 13 is removably fixed to the upper mold 11. Since the resin part 13 is removably attached to the upper mold 11, the resin part 13 can be removed from the upper mold 11 and easily replaced.

Further, as shown in FIG. 11, the bolt 14 is fastened to the Ensart 15 in a direction that intersects with the clamping direction of the upper mold 11. Thereby, the bolt 14 can be fastened without penetrating the molding surface 13a used for mold clamping. Therefore, the bolts 14 can be prevented from interfering with mold clamping by the resin part 13. In addition, in the modification shown in FIG. 11, it is desirable that the resin part 13 be molded in advance to match the shapes of the upper mold 11 and the base material 21. Thereby, there is no need to perform molding after newly replacing the resin part 13, and maintainability can be improved. Further, by molding the resin portion 13, it is possible to suppress the risk of erroneously deforming the molding surface portion 11a of the upper die 11.

To summarize the above, the mold 1 according to the first embodiment has the following configuration. In addition, in the following, the symbols shown in parentheses are the symbols corresponding to each structure shown in the above embodiment.

That is, the mold for the interior material is the mold (1) for the interior material (2) for press-bonding the skin material (22) to the surface of the base material (21) using the adhesive (23). A male mold (11) and a female mold (12) for crimping the base material (21) and the skin material (22) in an overlapping state by mold clamping, and a male mold (11) and/or a female mold (12). A non-adhesive resin part (13) is disposed at the peripheral edge to apply a pressure bonding force due to mold clamping to the end of the skin material (22). The resin part (13) applies pressure to the general surface of the base material (21) or skin material (22) formed on the male mold (11) and/or female mold (12) on which the resin part (13) is provided. A molding surface (13a) is formed flush with the metal molding surface (11a) by being buried in a recess that is recessed relative to the metal molding surface (11a) to be acted upon.

With this configuration, even if the adhesive (23) comes into contact with the resin part (13) during crimping, the resin part (13) has non-adhesive properties, so the adhesive (23) Adhesion can be suppressed and adhering adhesive can be easily peeled off. By providing the resin part (13) embedded in the mold (1), there is no need to repeat processes such as coating with a mold release agent, thereby preventing deterioration of workability.

Further, the resin part (13) is tightened with a bolt (14) fastened from a direction crossing the mold clamping direction to the male mold (11) and/or female mold (12) on which the resin part (13) is provided. It is removably fixed. With this configuration, the resin part (13) can be removed from the male mold (11) and/or the female mold (12) and easily replaced. Thereby, the maintainability of the mold (1) can be further improved. Moreover, by fastening the bolts (14) from a direction intersecting the mold clamping direction, it is possible to prevent the bolts (14) from interfering with mold clamping of the mold (1).

Further, the resin part (13) is arranged so as to extend endlessly along the end of the skin material (22) with respect to the male mold (11) and/or the female mold (12) on which the resin part (13) is provided. will be established. With such a configuration, the resin part (13) can apply pressure bonding force by mold clamping to the entire circumference of the end of the skin material (22).

Further, the resin part (13) is connected to the winding area (22e) of the winding part (22c) formed by winding the end of the skin material (22) to the back side of the base material (21), and the base material (21) before winding up. ) The overhanging region (22d) of the winding portion (22c) extends from the periphery of the winding portion (22c), and faces the winding portion (22c) over the entire area of the winding portion (22c) with a wider surface than each region. With such a configuration, the resin part (13) can appropriately cover the adhesion of the adhesive (23) by the rolled up parts (22c) before and after being rolled up.

Further, the resin portion (13) is a solid member made of fluororesin. With this configuration, by using the fluororesin, adhesion of the adhesive (23) to the resin part (13) can be appropriately suppressed, and the adhered adhesive (23) can be easily peeled off. Can be done. Further, by making the resin part (13) solid, the rigidity and durability of the resin part (13) can be increased compared to coating. Thereby, maintainability of the mold (1) can be improved.

<Second embodiment>
Next, a mold 101 according to a second embodiment of the present invention will be described. The mold 101 according to the present embodiment is different from the mold 1 according to the first embodiment in the configuration of the upper mold 111 and the lower mold 112 and in the molding procedure. Note that the same configurations as those shown in the first embodiment will be given the same reference numerals and the description will be omitted.

As shown in FIG. 12, the mold 101 has an upper mold 111 and a lower mold 112 made of metal. The mold 101 is configured to be clamped such that a concave upper mold 111 is fitted into a convex lower mold 112. The upper mold 111 has a molding surface portion 111a formed to match the shape of the surface of the base material 21. The base material 21 of the interior material 2 is set on the lower mold 112. Further, the lower mold 112 has a molding surface portion 112a formed to match the shape of the back surface of the base material 21, and a recessed portion 112b recessed with respect to the molding surface portion 112a. The recess 112b is formed at the periphery of the lower mold 112.

In this embodiment, the resin part 13 is provided not in the upper mold 111 but in the lower mold 112. Specifically, the resin part 13 is arranged in the recess 112b of the lower mold 112. The molding surface 13a of the resin portion 13 is formed flush with the molding surface portion 112a of the lower mold 112.

In the present embodiment, in the interior material 2, before the base material 21 and the skin material 22 are pressed together by the mold 101, the base material 21 and the skin material 22 are temporarily pasted together by an operator's hands. Specifically, first, the base material 21 is set on the molding surface portion 112a of the lower mold 112. The base material 21 is set with the surface facing upward. Next, a skin material 22 is placed over the base material 21. The skin material 22 is set so that the back surface to which the adhesive 23 is applied faces downward. Next, the worker presses the skin material 22 so as to match the surface shape of the base material 21. Thereby, the skin material 22 is temporarily attached to the base material 21. The above-mentioned temporary tensioning is carried out, for example, when the surface shape of the base material 21 is complex and it is difficult to achieve sufficient pressure bonding only by clamping with the mold 101. After the skin material 22 is temporarily attached to the base material 21, the upper mold 111 is lowered toward the lower mold 112 to be clamped. Thereby, the base material 21 and the skin material 22 are pressed together. In this way, the mold 101 manufactures the interior material 2.

When the skin material 22 is placed on the base material 21 from above, the rolled-up portion 22c of the skin material 22 before being rolled up protrudes from the periphery of the base material 21. As shown by the imaginary line in FIG. 12, the protruding rolled-up portion 22c collapses into contact with the side surface of the lower die 112 due to the action of gravity. However, the resin portion 13 extends to a wider surface than the overhanging region 22d of the rolled-up portion 22c. Thereby, the resin part 13 can suppress adhesion of the adhesive 23 to the lower die 112 due to the collapse of the rolled-up part 22c. Moreover, even if the adhesive 23 adheres to the resin part 13, it can be easily peeled off.
