Description

  The present invention relates to a structure around a hook portion of a trim provided on a wall portion of a vehicle interior.

  Some vehicles have a hook in the room to hang luggage such as shopping bags. Most of the hooks are provided on a trim that constitutes a wall portion of the vehicle interior. Some of these hooks are attached to a trim in a vehicle compartment as a separate part, as in Patent Document 1.

  However, in order to reduce the number of parts and reduce the cost, it is desirable to form the hook integrally with the trim. Such hooks and trims are generally manufactured by injection molding a resin material.

  When such an injection mold is used, it is desirable that no parting line is generated on the inner surface of the interior trim of the vehicle interior that serves as the design surface. Therefore, in such a mold structure, generally, a movable mold and a fixed mold are respectively arranged on the inner surface side of the trim and the outer surface side behind the inner surface, and the mold is connected to the inner surface of the trim. It is configured to be divided between the outer surface. With such a configuration, a parting line is generated between the inner surface and the outer surface, and the appearance of the vehicle interior is not impaired.

  In such a mold structure, it is conceivable to use a slide mold in order to produce a hook-shaped hook on the inner surface of the trim. This slide mold is configured to slide a part of a mold for producing a hook in a direction perpendicular to the mold dividing direction of the mold. Therefore, when taking out the product from the mold, the slide mold at the position of the hook at the time of molding slides and retreats from the product part of the mold. Therefore, the trim as a product and the slide mold do not interfere with each other, and the trim is taken out along the mold opening direction of the mold.

  However, when the slide mold is used, the structure of the mold becomes complicated, and the mold cost increases. In the slide type, a slide mark remains on the surface of the product. For this reason, it is not preferable to dispose the trim on the inner surface of the trim. In addition, usually, a textured surface is applied to the design surface of the vehicle interior, but a textured surface cannot be applied to a place where the slide mold is disposed. Therefore, it is difficult to use a slide mold for the inner surface of the trim.

  Therefore, a mold structure that does not use a slide mold on the inner surface side of the trim is generally employed. In this mold structure, the portion corresponding to the hook of one type on the outer surface side penetrates from the outer surface of the trim toward the inner surface, and is aligned with the portion corresponding to the hook of the other type on the inner surface side. The hook peripheral portion is formed. Therefore, a hole is formed in the vicinity of the hook of the trim after molding by penetrating a portion corresponding to the one-type hook.

In such a mold structure, resin is injected into the mold, the hook portion of the trim can be molded, and the trim can be taken out along the mold opening direction of the mold.

  However, in such a structure around the hook of the trim, the structure on the vehicle body side can be seen from the hole near the hook of the trim. Therefore, the appearance of the vehicle interior may be impaired, which is not preferable.

  Therefore, it is conceivable to improve the appearance of the vehicle by attaching a cover member for covering this hole, but it vibrates when the vehicle is running or when idling, and a rattling noise between the trim and the cover member is caused. There is a problem that abnormal noise occurs.

  Further, since a load is hung on the trim hook, the periphery of the trim hook needs to withstand the weight of the load. Therefore, if a hole is provided in the vicinity of the hook of the trim, the strength of the hook peripheral portion is not preferable.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to form a trim and a hook that are integrally molded to reduce the number of parts and reduce the cost, while preventing the appearance of the vehicle interior from being impaired and preventing the generation of abnormal noise.
