Holding the skin material with the peripheral portion sandwiched between the holding means and the second mold,
The gist is to close the first mold and the second mold and press the base material and the skin material together by pressing the peripheral portion of the skin material with the holding means.

  In the invention according to claim 2, as the first mold and the second mold are relatively brought closer, the holding means that presses the peripheral portion of the skin material against the second mold is removed from the first mold. The gist is to move it so that the amount of protrusion is small.

  The gist of the invention according to claim 3 is that a plurality of partial ranges of the peripheral portion of the skin material are pressed by a tip of the holding means formed in a bar shape.

  In the invention according to claim 4, the skin material is pressed by the holding means, and the skin material set in the second mold is held in the second mold by the negative pressure generated between the second mold and the second mold. The gist is to do.

In order to overcome the above-mentioned problems and achieve the intended purpose, the crimping device of the invention according to claim 5 of the present application is
A first mold that has a base material set portion shaped to match a base material formed in a three-dimensional shape, and can set the base material on the base material set portion;
A second mold capable of setting the skin material on the skin material set part, having a skin material set part of a shape matched to the skin material formed in a three-dimensional shape corresponding to the base material;
The first mold is provided so as to be capable of advancing and retreating with respect to the second mold, and the peripheral part extending from the main body part set in the skin material set part in the skin material is set in the base material set part. The gist of the invention is that the substrate is provided with a holding means for holding the peripheral portion of the skin material until it is pressed before the base portion hits the main body portion and the first mold and the second mold are closed.
According to the first and fifth aspects of the present invention, when the first mold and the second mold are closed relatively close to each other, before the base material hits the skin material, the holding means holds the second mold between the second mold and the second mold. Since the skin material is held with the peripheral portion sandwiched between them, the skin material can be prevented from being displaced even if the base material and the skin material are washed away. Further, the set means of the skin material can be corrected to an appropriate position by the holding means hitting the peripheral portion of the skin material. Thus, since the base material and the skin material are pressure-bonded while the skin material is appropriately held, the occurrence of defects such as wrinkles in the skin material can be suppressed and a vehicle interior member excellent in quality can be obtained. .

In the invention according to claim 6, the holding means is urged so as to protrude toward the second mold, and the first means and the second mold are relatively close to each other. The gist is to move so that the amount of protrusion from the first mold is reduced by being pushed by the second mold.
According to the second and sixth aspects of the invention, the holding means is pushed by the second mold and retreats with the relative proximity of the first mold and the second mold, so the holding means is the first It is possible to simplify the configuration in which the holding means is advanced and retracted without obstructing the mold closing of the mold and the second mold.

The gist of the invention according to claim 7 is that the holding means is formed in a rod shape and presses a partial range of the peripheral portion of the skin material at its tip.
According to the inventions according to claims 3 and 7, since the partial range of the skin material is suppressed by the tip of the holding means formed in a rod shape, even if the peripheral portion of the skin material has a three-dimensional shape, Thus, the peripheral portion can be appropriately pressed by the holding means.

The gist of the invention according to claim 8 is that the second mold is provided with negative pressure holding means for holding the main body portion of the skin material by negative pressure in the skin material set portion.
According to the invention according to claim 4 and claim 8, since the peripheral portion of the skin material is pressed by the holding means, the generation of a gap between the second mold and the peripheral portion of the skin material is prevented, A negative pressure can be more appropriately generated between the skin material. Therefore, the skin material can be held at a more appropriate position with respect to the second mold.

The second mold 34 has negative pressure holding means (not shown) for holding the set state of the skin material 14 by vacuum suction or the like. The second mold 34 of the embodiment sucks air from a suction hole opened in the skin material set portion 38 and generates a negative pressure between the main body portion 14 a of the skin material 14 set in the skin material set portion 38. The main body portion 14a is attracted and held to the mold surface of the skin material setting portion 38 by the negative pressure holding means.

  As shown in FIGS. 2 to 4, the first mold 32 includes a base material surface portion 40 provided around (outside) the convex base material set portion 36. The second mold 34 includes a skin material surface portion 42 provided around (outside) the concave skin material set portion 38, and the base material surface portion 40 and the skin material surface portion 42 close the crimping device 30. Relative to The second mold 34 supports the body portion 14a which is a portion exposed to the front side in the skin material 14 with the skin material set portion 38, and the skin material 14 has a peripheral edge portion 14b extending outside the body portion 14a with the skin material surface portion 42. It comes to support.

  As shown in FIGS. 2 to 4, the crimping device 30 is provided on the base surface portion 40 of the first mold 32 and can hold the peripheral portion 14 b of the skin material 14 set on the second mold 34. It has. The holding means 44 is provided in the first mold 32 so as to be able to advance and retreat with respect to the skin material surface portion 42 of the second mold 34, and is protruded from the substrate surface portion 40 by the advance / retreat means 46 (see FIG. 2). It is configured to move between a retracted state (see FIG. 4A) that is housed in the first mold 32 and does not protrude from the base material surface portion 40 or the amount of protrusion from the base material surface portion 40 is minimized. In the embodiment, as the advance / retreat means 46, an urging means such as a spring for urging the holding means 44 toward the second mold 34 is used.

  The holding means 44 is always urged toward the protruding state by the advancing and retracting means 46, and is in the protruding state with the first mold 32 and the second mold 34 opened (FIGS. 2 and 3A). ), The tip facing the skin material surface portion 42 is disposed at a position away from the skin material surface portion 42. When the holding means 44 approaches the first mold 32 and the second mold 34, the tip of the holding means 44 is restricted to move to the skin material surface portion 42 (FIG. 3B), and the first mold 32 and the second mold 34 from this contact state. When the first mold 32 and the second mold 34 are closed, they are moved to the retracted state by being pushed by the skin material surface portion 42 (FIG. 4A). When the first mold 32 and the second mold 34 are opened from the closed state, the holding means 44 moves toward the protruding state by the urging force of the advance / retreat means 46, and protrudes when the tip is separated from the skin material surface portion 42. (FIG. 4B).

  As shown in FIGS. 2 to 4, the holding means 44 is formed in a rod shape having an axis (longitudinal) extending in the advancing / retreating direction thereof, and in the embodiment, has a round bar shape. Further, the holding means 44 is formed with a curved smooth shape such as a hemispherical (example) or a flat surface with chamfered corners, etc., and a peripheral portion of the skin material 14. It corresponds to a partial range in 14b. Corresponding to the peripheral portion 14b of the skin material 14 extending so as to surround the four sides of the main body portion 14a, the first mold 32 has a base material surface portion 40 provided so as to surround the four sides of the base material setting portion 36. On each side, a plurality of holding means 44 are arranged apart from each other.

  Next, a manufacturing method according to an embodiment using the above-described crimping apparatus 30 will be described. The base material 12 molded into a predetermined three-dimensional shape is prepared by a molding method such as injection molding (FIG. 2). Further, the skin material 14 formed into a predetermined three-dimensional shape is obtained by a molding method such as vacuum forming, and a stitch pattern 16 is formed by sewing a predetermined portion of the skin material 14 with a sewing machine (FIG. 2). ). In this manner, the skin material 14 is prepared in a shape that has a stitch pattern 16 and is shaped into a predetermined shape. Here, the base material 12 is basically formed in accordance with the outer shape of the vehicle interior member 10 to be obtained, whereas the skin material 14 has a peripheral portion 14b from the main body portion 14a covering the base material 12 in all directions. It is formed larger than the base material 12 so as to extend.

  The base material 12 with the adhesive applied to the front side surface is fitted to the base material set part 36 so that the back side surface faces the base material set part 36 and set to the first mold 32 (FIG. 3 ( a)). For the skin material 14, the body portion 14a is fitted to the skin material set portion 38 so that the front surface of the body portion 14a faces the mold surface, and the peripheral portion 14b protruding from the skin material set portion 38 is covered with the skin. It arrange | positions to the material surface part 42 (Fig.3 (a)).

  Next, the first mold 32 is moved so as to approach the second mold 34, and the first mold 32 and the second mold 34 are closed (FIG. 3B). When the first mold 32 is closed close to the second mold 34, the holding means 44 in the protruding state is applied to the peripheral portion 14b of the skin material 14 before the base material 12 hits the main body portion 14a of the skin material 14, The peripheral edge portion 14b is sandwiched between the holding means 44 and the skin material surface portion 42 of the second mold 34 to hold the skin material 14 so as not to move (FIG. 3B). Even if the peripheral portion 14b of the skin material 14 is set on the second die 34 in a shifted state, such as floating from the second die 34, the skin material 14 is pushed by the holding means 44 as the die is closed. The peripheral portion 14b is set at an appropriate position.

  As the first mold 32 is brought closer to the second mold 34, the holding means 44 in a state in which the peripheral portion 14b of the skin material 14 is pressed against the skin material surface portion 42 is pushed by the skin material surface portion 42, and the advance / retreat means 46 It moves so that the amount of protrusion from the base material surface portion 40 becomes smaller against the urging force. The first mold 32 and the second mold 34 are closed while the peripheral portion 14b of the skin material 14 is elastically pressed by the holding means 44, and the surface of the base material 12 to which the adhesive is applied and the skin material 14 The back surface of the main body portion 14a is brought into contact with each other, and the base material 12 and the main body portion 14a of the skin material 14 are pressure-bonded by being sandwiched between the base material setting portion 36 and the skin material setting portion 38 (FIG. 4A). Thus, during crimping, each side of the peripheral portion 14b of the skin material 14 extending so as to surround the four sides of the main body portion 14a is held by the plurality of holding means 44 that are arranged apart from each other, and the skin material 14 is The second mold 34 is held so as not to be displaced inward.

  In the second mold 34, the holding timing of the skin material 14 by the negative pressure holding means is set after the main body portion 14 a is set on the skin material setting portion 38, or the holding portion 44 holds the peripheral portion 14 b against the skin material surface portion 42. It is possible to select an appropriate time before the base material 12 and the main body portion 14a of the skin material 14 are crimped, such as after attaching. In the embodiment, after the main body portion 14a is set on the skin material setting portion 38, before the mold closing is started, the second mold 34 starts to hold the skin material 14 by the negative pressure holding means and closes the mold. The holding | maintenance of the skin material 14 by a negative-pressure holding means is maintained over this.

  After the base material 12 and the main body portion 14a of the skin material 14 are pressure-bonded, the first mold 32 and the second mold 34 are opened (FIG. 4B), and the obtained pressure-bonded product is taken out (FIG. 5A). ), The vehicle interior member 10 is subjected to a predetermined post-treatment such as wrapping and bonding the peripheral portion 14b of the skin material 14 to the back side of the base material 12 or cutting the peripheral portion 14b of the skin material 14. Is obtained (FIG. 5 (b)).

  As described above, when the first mold 32 and the second mold 34 are closed, before the base material 12 comes into contact with the main body portion 14a of the skin material 14, the skin member surface portion 42 of the second mold 34 is held by the holding means 44. The skin material 14 is held with a peripheral edge portion 14b interposed therebetween. Thus, even when the base material 12 and the main body portion 14a of the skin material 14 are in contact with each other during the mold closing, the outer skin material 14 is pressed by the holding means 44 and moved inward. Therefore, it is possible to avoid displacement of the skin material 14. Even if the peripheral portion 14b of the skin material 14 is set in a state of being lifted from the skin material surface portion 42 of the second mold 34, the holding means 44 hits the peripheral portion 14b of the skin material 14, It can correct | amend to an appropriate set position, and the contact itself with the base material 12 and the main-body part 14a of the skin material 14 in the middle of mold closing can be suppressed. Thus, since the base material 12 and the skin material 14 are pressure-bonded while the skin material 14 is appropriately held with respect to the second mold 34, the occurrence of defects such as wrinkles in the skin material 14 is suppressed, and the quality is improved. Can be obtained.

  The holding means 44 is pushed by the second mold 34 and retracts so that the amount of protrusion decreases as the first mold 32 and the second mold 34 approach each other. It does not get in the way of mold closing with 2 type 34. Since the holding means 44 urged by the advance / retreat means 46 is moved forward and backward by opening and closing the first mold 32 and the second mold 34, for example, the first mold 32 and the second mold using drive means such as a cylinder. Compared to a configuration in which the holding unit 44 is advanced and retracted in conjunction with opening and closing with the unit 34, the configuration in which the holding unit 44 is advanced and retracted is simple. Moreover, since the holding means 44 urged by the advance / retreat means 46 elastically presses the peripheral portion 14b of the skin material 14, excessive load on the peripheral portion 14b can be reduced, and the peripheral portion 14b has a hole, etc. Breakage can be prevented.

  As described above, since the partial range of the skin material 14 is pressed by the tip of the holding means 44 formed in a rod shape, the peripheral portion 14b of the skin material 14 has a three-dimensional shape, and a shape corresponding to the three-dimensional shape. Even the outer skin material surface portion 42 can appropriately hold the peripheral edge portion 14b by the holding means 44. Therefore, the skin material 14 can be held by pressing the holding means 44, and the quality of the skin material 14 that forms the surface of the vehicle interior member 10 obtained can be improved.

  As described above, by holding the peripheral portion 14 b of the skin material 14 by the holding means 44, it is possible to prevent a gap from being formed between the skin material surface portion 42 of the second mold 34 and the peripheral portion 14 b of the skin material 14. Thereby, a negative pressure can be more appropriately generated by the negative pressure holding means between the skin material setting portion 38 of the second mold 34 and the main body portion 14 a of the skin material 14. Therefore, the skin material 14 can be held at a more appropriate position with respect to the second mold 34.

  Unevenness due to holding of the holding means 44 may be formed on the peripheral portion 14 b of the skin material 14. However, since the peripheral portion 14b is removed by cutting or wound around the back side of the base material 12, even if irregularities due to the holding means 44 are formed in the peripheral portion 14b of the skin material 14 in the manufacturing process, Irregularities do not lead to deterioration of the quality of the vehicle interior member 10.
