  However, in the above-described conventional technology, the mounting portion (the portion where the mounting surface 214a of the base 214 of the resin clip 210 is joined) 250a on the inner surface of the resin window 250 has a shape (curved surface) curved toward the inner surface side. (See FIG. 12). Therefore, as shown in FIG. 12, the mounting surface 214a of the base 214 of the resin clip 210 must also be formed in an inclined shape so as to follow this curved shape. Accordingly, as shown in FIG. 11, when the resin window 250 is attached to the vehicle body via the three resin clips 210, the bending directions of the pair of locking legs 212 a of the attachment portions 212 of the three resin clips 210. In some cases, the angle of each base portion 214 in plan view in the direction of inclination (the angle when viewed in plan) differs for each resin clip 210. That is, in these three resin clips 210, even if each attachment portion 212 is common, the shape of each base portion 214 with respect to each attachment portion 212 may be different. As a result, these three resin clips 210 cannot be shared, and a molding die for molding these three resin clips 210 has been required individually.

  The present invention is intended to solve such a problem, and its purpose is to form a molding die for molding a resin clip even if the shape of a base attached to a resin molded product having a transparent or translucent portion is different. Is to share.

It is necessary to form an inclined shape along the attachment site. In such a case, when a resin molded product is attached to the vehicle body via a plurality of (for example, three) resin clips, the inclination of each base portion with respect to the bending direction of the pair of locking legs of each attachment portion of each resin clip An angle in a plan view of the direction (an angle when seen in a plane) may be different for each resin clip. However, even in such a case, since the concave surface of the cavity can be rotated, the plurality of resin clips can be formed without requiring replacement of the insert body.

  The invention according to claim 3 is the molding die for the resin clip according to any one of claims 1 to 2, wherein the nesting body has a depth position of the cavity where the base portion of the resin clip is molded. It is the structure characterized by being formed so that adjustment is possible.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. In the following description, a mode in which “resin molded product having a transparent or translucent portion” is “resin window 250” will be described. The same applies to Example 2 described later.

Example 1
First, Embodiment 1 of the present invention will be described with reference to FIGS. First, with reference to FIG. 1, the molding die 1 which concerns on Example 1 is demonstrated. The molding die 1 includes a fixed die 2 fixed to a floor floor (not shown) and a movable die (not shown) that can be clamped and opened with respect to the fixed die 2. Yes.

  In FIG. 1, the movable mold can be clamped and opened with respect to the fixed mold 2 in the depth direction in front of the paper surface. Therefore, this movable mold is not shown in each drawing. When the fixed mold 2 and the movable mold are clamped to the molding mold 1 composed of the fixed mold 2 and the movable mold, a vehicle body (not shown) is provided as in the description of the prior art. The cavity 20 capable of forming the resin clip 10 for attaching the resin window 250 is formed.

  As shown in FIGS. 2 to 3, the resin clip 10 also has an attachment portion 12 attached to an attachment hole (not shown) of the vehicle body and a columnar base portion attached to the resin window 250 as in the description of the prior art. 14 and is integrally molded with resin. Of the cavities 20, the cavities 20 that mold the base portion 14 of the resin clip 10 are constituted by a nesting body 22 that can be attached to and detached from the molding die 1 itself.

  Returning to FIG. 1, the nesting body 22 includes a fixed nesting 30 for molding the outer peripheral surface of the base portion 14 of the resin clip 10 and a movable nesting 40 for molding the bottom surface of the base portion 14. A screw groove 32 is formed on the inner peripheral surface of the fixed insert 30. On the other hand, a thread 42 that is screwed into the thread groove 32 is formed on the outer peripheral surface of the movable insert 40. Therefore, the movable nest 40 is assembled with a transmission member 44 that transmits a rotational force from a drive source (not shown) so that the movable nest 40 itself can be rotated about its axis.

  Further, as described in the prior art, the cavitating surface 40a of the movable insert 40 is such that the mounting surface 14a of the base portion 14 of the resin clip 10 to be molded follows the curved shape of the mounting portion 250a of the resin window 250. It is formed in an inclined shape. Further, a protrusion 40b is formed on the cavity surface 40a of the movable nest 40 so that the mounting surface 14a of the base 14 of the resin clip 10 to be molded has a ring-shaped groove 14b. Thereby, while cooling time of the resin clip 10 after shaping | molding can be shortened, generation | occurrence | production of sink can be suppressed. The molding die 1 is configured in this way.

  Next, the operation of the molding die 1 described above will be described. When the drive source is rotated, the transmission member 44 is also rotated, so that the movable nest 40 is rotated with respect to the fixed nest 30 along with this rotation. Thereby, since the movable insert 40 slides with respect to the fixed insert 30, the depth position of the cavity 20 in which the base portion 14 of the resin clip 10 is formed can be adjusted to a desired position (see FIG. 4). At this time, since the degree of rotation of the movable insert 40 can be arbitrarily adjusted, the angle in plan view between the bending direction of the pair of locking legs 12a of the mounting portion 12 of the resin clip 10 and the inclination direction of the base portion 14 is also desired. The angle can be adjusted (see FIG. 5).

  The molding die 1 according to the first embodiment of the present invention is configured as described above. According to this configuration, of the cavities 20 for molding the resin clip 10, the cavities 20 for molding the base portion 14 of the resin clip 10 are formed by the nesting body 22 that can be attached to and detached from the molding die 1 itself. Therefore, when the insert 22 is assembled to another insert, the base 14 having various shapes can be formed in the resin clip 10 without changing the shape of the attachment portion 12. Therefore, even if the shape of the base part 14 in the resin clip 10 is different, the molding die 1 for molding the resin clip 10 can be shared.

  Further, according to this configuration, the nesting body 22 includes the fixed nesting 30 that forms the outer peripheral surface of the base portion 14 of the resin clip 10 and the movable nesting 40 that molds the bottom surface of the base portion 14. A screw groove 32 is formed on the inner peripheral surface of the fixed insert 30. On the other hand, a thread 42 that is screwed into the thread groove 32 is formed on the outer peripheral surface of the movable insert 40. Therefore, when the drive source is rotated, the transmission member 44 is also rotated, so that the movable nest 40 is rotated with respect to the fixed nest 30 along with this rotation. Therefore, the concave surface 20 a of the cavity 20 that forms the mounting surface 14 a of the base portion 14 of the resin clip 10 can be rotated with respect to the mounting portion 12 of the resin clip 10.

  In addition, when the attachment site | part 250a which attaches the resin clip 10 in the resin window 250 is inclined with respect to the attachment surface of a vehicle body, the attachment surface 14a of the base 14 of the resin clip 10 is also attached to this resin window 250. It is necessary to form it in an inclined shape along the part 250a.

  In such a case, when the resin window 250 is attached to the vehicle body via a plurality (for example, three) of the resin clips 10, the bending direction of the pair of locking legs 12 a of the attachment portions 12 of the resin clips 10 is determined. The angle in plan view of each base portion 14 in the inclination direction (when viewed in plan) may be different for each resin clip 10. However, even in such a case, since the concave surface 20a of the cavity 20 can be rotated, the plurality of resin clips 10 can be molded without the need to replace the insert 22.

  Further, according to this configuration, when the drive source is rotated, the transmission member 44 is also rotated, so that the movable nest 40 is rotated with respect to the fixed nest 30 with this rotation. Thereby, the movable insert 40 slides with respect to the fixed insert 30. Therefore, the depth position of the cavity 20 in which the base portion 14 of the resin clip 10 is molded can be adjusted to a desired position. Therefore, even when it is desired to change the height length of the base portion 14 of the resin clip 10, the plurality of resin clips 10 can be formed without requiring replacement of the insert body 22.

  Moreover, according to this structure, the resin clip 10 is shape | molded by the molding die 1 mentioned above. Therefore, even if the shape of the base 14 attached to the resin window 250 in the resin clip 10 is different, the molding die 1 for molding the resin clip 10 can be shared.

(Example 2)
Next, Embodiment 2 of the present invention will be described with reference to FIG. Compared with the molding die 1 of the first embodiment already described, the molding die 101 of the second embodiment is screwed to adjust the rotation of the concave surface 20a of the cavity 20 that molds the mounting surface 14a of the base portion 14 of the resin clip 10. It is a form that can be simplified without requiring a match. In the following description, the same or equivalent members as those described in the first embodiment are denoted by the same reference numerals in the drawings, and redundant description will be omitted.

  As shown in FIG. 6, the fixed insert 30 and the movable insert 40 described in the first embodiment are integrally formed as a cylindrical insert 122. The insert 122 is assembled to the fixed mold 2 so as to be rotatable around its axis. The rotation position is fixed by a set screw (not shown) from the side surface of the fixed mold 2.

  The molding die 101 according to the second embodiment of the present invention is configured as described above. According to this configuration, it is possible to obtain the same effects as those of the first embodiment. Further, since the rotational position of the insert body 122 with respect to the stationary mold 2 is fixed with the screw screw, the screwing described in the first embodiment is not required. Therefore, the rotation position of the nested body 122 can be fixed with a simple configuration.

The contents described above are only related to one embodiment of the present invention, and do not mean that the present invention is limited to the above contents.
In the first embodiment, the mode in which the movable insert 40 screwed to the fixed insert 30 is rotatable via the transmission member 44 has been described. However, the present invention is not limited to this, and the movable insert 40 may not be screwed to the fixed insert 30. In that case, instead of the transmission member 44, a piston (not shown) of the cylinder is assembled to the movable nest 40, and the movable nest 40 slides with respect to the fixed nest 30 by expansion and contraction of the piston.

  Moreover, in Example 2, the nested body 122 demonstrated the form which is a column shape. However, the present invention is not limited to this, and the nested body 122 may have a polygonal column shape (for example, a hexagonal column shape). Thus, for example, when the nested body 122 has a polygonal column shape, the nested body 122 can be assembled to the fixed mold 2 only at predetermined angles. For example, when the nested body 122 has a hexagonal column shape, the nested body 122 can be assembled to the fixed mold 2 only every 60 °. Therefore, the rotation angle of the nested body 122 can be easily adjusted. That is, an angle fine adjustment operation or the like becomes unnecessary.

  Moreover, in each Example, the protrusion 40b is formed in the cavitating surface 40a of the movable nest 40 so that the attachment surface 14a of the base 14 of the resin clip 10 to be molded has a ring-shaped groove 14b. explained. However, the present invention is not limited to this, and as shown in FIGS. 7 to 8, the groove 14 b may have a plurality of circular shapes and / or a ring shape concentric with the circular shapes (Modifications 1 and 2). ). Moreover, it is not limited to this, As shown in FIGS. 9-10, the attachment surface 14a of the base 14 of the resin clip 10 to be molded has a plurality of circular legs or ring-shaped legs concentric with the circular shape. (Modifications 3 to 4).

  Further, in each of the embodiments, the form in which the “resin molded product having a transparent or translucent portion” is the “resin window 250” has been described. However, the present invention is not limited to this, and “resin molded product having a transparent or translucent part” is “extra window”, “exterior part having transparent or translucent part”, “front grill”, “rear door” It may be a rear garnish attached to.
