DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molded article structure formed by a mold having no slide pieces, and more particularly, to a molded article structure which can be normally formed by a mold having a slide piece.

[0002]

2. Description of the Related Art Conventionally, a molded product formed by a mold has only a molding surface on which a transfer surface of a fixed mold and a movable mold is transferred, that is, a first molding surface and a first molding surface which intersect with the mold opening direction. Although only the second molding surface is parallel to the mold opening direction, complicated shapes can be produced by molding with the recent advancement of molding technology.

As this type of molded product, for example, a protector for protecting a wire harness shown in FIG. 5 is also produced by molding. This protector protects the protector body 1 with a cover 2 so as not to be damaged by an external influence when the wire harness is routed at a corner of the vehicle body. A pair of clips 3a, 3b are pushed into and engaged with the mounting holes (2), and are mounted.

[0004]

However, in such a conventional protector, the clip 3a is attached to the cover 2a.
Therefore, there is a problem in that molding cannot be performed without using a mold provided with a slide piece that moves in the molding space, resulting in an increase in cost.

In order to form this protector at low cost, as shown in FIG. 6, a hole (opening) of a die member for transferring a transfer surface to the clip 3a is provided at a position facing the clip 3a of the lid 2. By providing 4, the molding can be performed without using a slide piece. However, since the wire harness may be exposed from the hole 4 and protrude, there is also a problem that the protection function, which is the original function, is deteriorated. Depending on a place where the protector is attached, the hole 4 may be set. May not be possible. In this case, as shown in FIG. 7, the clip 3a may be omitted, but if omitted, there is a problem that stability (fixation) deteriorates.

In order to solve this problem, for example, Japanese Utility Model Publication No. Hei 7-24894 discloses a protector in which a member serving as an inner lid larger than the hole 4 is integrally formed. However, there is a problem that the space for passing the wire harness is narrowed due to the overlapping portion because the wire is too large. In addition, securing the space is an important factor because the wire harness is routed in a narrow place.

Accordingly, the present invention provides a structure in which a required shape of a punched hole of a mold provided so as not to hinder molding can be engaged and held after the mold is removed from the mold. It is an object of the present invention to obtain a shape that cannot be obtained by using a mold without a mold, and to make a desired shape by inexpensive molding.

[0008]

In order to achieve the above object, according to the first aspect of the present invention, the mold is formed by a mold having no slide piece moving in a molding space, and intersects with the mold opening direction of the mold. A first molding surface and a second molding surface parallel to the mold opening direction.

Therefore, the protector body 1 and the lid 2 are provided on the upper surface of the vehicle body corner. Clip 3a formed on both sides of the upper part of the protector body 1,
When 3b is pushed into the mounting hole drilled in the upper surface of the corner from the head, a pair of bending portions expanding in the shape of an arrow are elastically deformed and return to their shapes, thereby engaging with the mounting hole.

The protector 10 includes a protector body 1.
Side walls 5a and 5b are provided in the upper and side portions of the side walls 5a and 5b to secure a space for arranging a wire harness, and the lid 2 is provided with a hinge formed at an upper end of one side wall 5a. It is rotatably supported by the portion 6 and defines a space in which the wire harness is routed facing the protector body 1 in use. Further, the lid 2 is formed from the upper portion to the side portion where the hole 4 of the mold member is supported by the hinge portion 6 to form a first molding surface A of the clip 3a and the extension portion 7a which will be described later. The part is cut open.

The clips 3a and 3b are erected on the lower surfaces of the extending portions 7a and 7b extending outward from the side walls 5a and 5b from the upper portion of the protector main body 1 so that the bent portions extend in the extending direction. Have been. The engagement (lock) between the protector main body 1 and the lid 2 may be such that a lock mechanism may be formed on the side wall 5b and one side of the lid 2 which are close to each other when facing each other, or tape may be wound.

Reference numeral 12 denotes a rotating lid. The rotating lid 12 is formed so as to have the same shape as the portion of the lid 2 cut out to form a hole (opening) 4, 1 is rotatably supported by a hinge portion 13 provided at the edge of the through hole 4 and has a surface that is continuous with the lid 2 (in FIG. 1A,
When rotated clockwise, it forms a part of the lid 2 which is not cut off. This rotating lid 12
Engages with the convex engaging projection 15 formed on the outer surface of the side wall 5a when the lid 2 is rotated in a state of defining a space in which the wire harness is routed facing the protector main body 1. Claws 14
A lock portion 14 for hooking and engaging a is provided on one side on the hinge portion 6 side, and can define (close) a space in which a wire harness is routed similarly to the lid 2. That is, the lid 2 serves as a rotating member, the rotating cover plate 12 serves as an opposing portion, the hinge portion 13 serves as a rotating support portion, the lock portion 14 and the engaging convex portion 15.
Constitutes an engagement means, and the clip 3a and the extending portion 7a constitute a part of the first molding surface.

Since the protector 10 is formed with the lid 2 opened, the first molding surface A (FIG. 1) in which both sides of the protector body 1 and the lid 2 intersect with the mold opening direction of the mold. , The plane orthogonal to the arrow A) and the protector body 1
In addition, the upper and lower surfaces of the upper portion of the lid 2 and the side surfaces of the side wall 5 become a second molding surface B (a surface orthogonal to the arrow B in FIG. 2) which coincides with the mold opening direction of the mold. Then, at the time of this molding, the rotating lid 12 is set in a state where the punched hole 4 is opened to form the molding surface A of the clip 3a and the extending portion 7, so that the clips 3a and 3b and the extending portions 7a and 7b are formed. Can be formed as being composed of the molding surfaces A and B, and the rotating lid 12 can also be molded as having the molding surfaces A and B including the lock portion 14. Therefore, the protector 10 can be rotated together with the clip 3a and the extension 7a.
