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 a molded product of this type, for example, a protector for protecting a wire harness shown in FIG. 9 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. 10, a hole 4 of a die member for transferring a transfer surface to the clip 3a is provided at a position of the cover 2 facing the clip 3a. Thereby, 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. 11, 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 of a hole 4 is integrally formed.
There is a problem that the space for passing the wire harness is narrowed due to the overlapped portion because the wire harness is formed separately. In addition, securing the space is an important factor because the wire harness is routed in a narrow place.

Therefore, the present invention is not possible with a mold without a slide piece by adopting a structure in which a portion to be provided at a position obstructing molding can be taken out of the mold and engaged and held at that position. It is an object of the present invention to obtain a desired shape by inexpensive molding so that a desired shape can be obtained.

[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.
Wire harness protector structure with only a molding surface
A granulation, a rotating member which is opposed molding surfaces of the first to the molded article body by a the pivoting is rotatably supported on the molded article body has a first shaping surface, An engaging member having an engaging portion that engages with the molded article main body after molding, and an opposing portion that faces the rear surface side of the first molding surface of the rotating member when the engaging portion is engaged; A rotating support portion rotatably supported in a direction intersecting with the second molding surface of the molded article main body is formed integrally with the molded article main body.

According to the first aspect of the present invention, the rotating member,
The engaging member and the rotation supporting portion are formed integrally with the molded article main body only by the first and second molding surfaces, and after taking out from the mold, the engaging member is rotated via the rotation supporting portion. , The opposing portion of the engaging member is a back surface of the first molding surface of the rotating member .
The engaging portion engages with the molded article main body while facing the side .
Therefore, when molding because it faces the facing part,
It is possible to omit the hole of the mold set for the rotating member.
And an opposing portion provided on the back side of the first molding surface with a rotating member.
It can be formed by no sliding piece mold molded product that must be disposed of.
