Description

  The present invention relates to a seal material mounting portion structure and a seal material structure of a powder slush molding apparatus.

  A vehicle such as an automobile is provided with an interior panel such as an instrument panel in the front part of the vehicle interior. Some of such interior panels have a skin material formed by a powder slush molding device.

  The powder slush molding device attaches a heated mold in a sealed state to the opening edge of a reservoir container that can accommodate a powder material, and rotates the reservoir container and the mold to rotate the powder onto the mold. The material is formed by melting and adhering.

  A sealing material that can be sealed against the mold is attached to the opening edge of the reservoir container via a sealing material attachment.

  The seal material has a seal body portion capable of sealing against the mold on the tip side, and has a mounting portion for the seal material fitting and the opening edge of the reservoir container at the base portion (for example, patent) Reference 1).

  As shown in FIG. 3, the sealing material 1 described in the above document is made of a rubber-based material made of a solid silicon material, and includes a hollow tubular sealing body 2 and a mounting portion having a substantially cross-shaped shape. 3.

  As shown in FIG. 4, the hollow tubular seal body 2 is relatively thick, the upper half in contact with the mold is a substantially semi-cylindrical portion 4, and the lower half on the mounting portion 3 side is substantially the same. The half-angle cylindrical portion 5 is used. The internal space 6 of the hollow tubular seal main body 2 is hollow or an inner material is inserted therein.

  The substantially cross-shaped mounting portion 3 has a neck portion 7, both arm portions 8, and leg portions 9. The leg portion 9 has a tapered shape.

  Further, as shown in FIG. 3, the opening edge portion 11 of the reservoir container has a substantially flat portion 12 capable of directly abutting and supporting the both arm portions 8 of the mounting portion 3 on its end surface (upper end surface in the figure). ing. A concave groove portion 13 that can accommodate and hold the leg portion 9 of the mounting portion 3 is formed at the center portion of the flat portion 12 in the width direction. The concave groove portion 13 has a substantially V-groove shape corresponding to the leg portion 9 of the mounting portion 3.

  The sealing material fixture 14 is a pair of L-shaped metal fittings 15 that can be disposed in contact with both inner and outer side surfaces of the opening edge 11 of the reservoir container (only one side is shown). The L-shaped metal fitting 15 has a locking portion 16 bent in a hook shape at the tip. Further, the L-shaped metal fitting 15 has a long hole 18 for position adjustment extending in the vertical direction in the figure in the main body portion 17 along the side surface of the opening edge 11 of the reservoir container. Then, the bolt 19 can be fastened to the side surface of the opening edge portion 11 of the reservoir container through the long hole 18.

  According to such a configuration, both arms 8 of the mounting portion 3 of the sealing material 1 are brought into contact with the flat portion 12 of the upper end surface of the opening edge portion 11 of the reservoir container, and the leg portion 9 is in contact with the concave groove portion 13. In the state of fitting, the L-shaped metal fitting 15 which is the sealing material attachment 14 is disposed in contact with both the inner and outer side surfaces of the opening edge 11 of the reservoir container. The bent locking portion 16 is locked to the neck portion 7 of the sealing material 1, and finally, the sealing material is screwed onto the side surface of the opening edge portion 11 of the reservoir container through the bolt 19 from the outside through the long hole 18. 1 is attached. At this time, the vertical position of the L-shaped metal fitting 15 is adjusted by the long hole 18.

When a heated mold is attached to the opening edge 11 of the reservoir container, the hollow tubular seal body 2 is crushed almost flat, thereby sealing the mold. The seal load at this time is transmitted to the upper end surface of the opening edge portion 11 of the reservoir container through the entirety of the substantially cross-shaped mounting portion 3, and the upper end surface receives this.

In addition, there is a problem that the height of the sealing material 1 cannot be adjusted (adjustment of the seal allowance for the mold of the seal body 2).

  In addition, since the seal material fitting 14 is a simple L-shaped metal fitting 15, it takes time to engage the locking portion 16 bent in a hook shape with the neck portion 7 of the sealing material 1, and the seal body 2. Since it takes a considerable amount of time to adjust the seal margin for the metal mold, the replacement of the seal material 1 has been a work requiring skill.
