Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a trim member for an automobile trunk and a mold thereof. More specifically, the present invention relates to improvements in a trim member made of nonwoven fabric, recycled felt, etc., into a box shape and forming the inner wall of an automobile trunk, and in the molding process of the mold.

[Prior Art] Conventionally, as a trim member for the trunk of an automobile, those shown in FIGS. 10 and 11, for example, are known.

This conventional car trunk trim member is
Floor surface 1, front surface 2, side surfaces 3 on both sides,
It has a box shape with an open top surrounded by a rear surface 4, and a storage convex portion 5 for storing a trunk lid locking mechanism is provided on the rear surface 4 to protrude inside.

In such a car trunk trim member, the storage convex portion 5 is a so-called undercut.
It is known to perform molding using a mold as shown in FIG.

The mold for this automobile trunk trim member consists of a male die 10 and a female die 20 to be pressed.
A slide mold 40 that is slid by a cylinder 30 is provided on the female mold 20 corresponding to the storage convex portion 5 serving as an undercut. That is, during stamping and die cutting, the cylinder 30 slides the slide die 40 to form the undercut storage convex portion 5.
This is to avoid.

[Problems to be Solved by the Invention] In the above-mentioned conventional means for forming a trim member for a trunk of an automobile, the manufacturing cost of the mold increases due to the cylinder 30 and the slide mold 40, and furthermore, There is a problem that the molding process becomes troublesome due to the above-mentioned factors.

The present invention was made in order to solve these problems, and the purpose is to provide a trim member for an automobile trunk that is inexpensive to manufacture and easy to mold, and a mold for the trim member. Our goal is to provide the following.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the trim member for an automobile trunk according to the present invention (claim 1) includes the following:
It consists of a box shape with an open top surrounded by the floor surface, front surface, side surfaces on both sides, and rear surface, with a storage protrusion protruding inside to store the trunk lid locking mechanism on the rear surface. In a trim member for a trunk of an automobile, a notch is formed between the rear surface and the side surface by cutting out a part of the side surface from a molded product of the trim member, and the rear surface and side surface separated by this notch are This joint assembly absorbs the difference between the molding angle of the rear surface and the product angle.

Further, the mold for a trim member for a trunk of an automobile according to the present invention (claim 2) consists of a box shape with an open top surrounded by a floor surface, a front surface, both side surfaces, and a rear surface, This is a trim member for an automobile trunk that has a protruding storage convex portion on the rear surface for housing a trunk lid locking mechanism, and is molded using both male and female presses. In a mold for a trim member for a trunk of an automobile, a means is adopted in which the molding angle between the rear surface and the floor surface is set to be an obtuse angle larger than the actual product angle.

[Function] According to the above-mentioned method, the forming angle between the rear surface and the floor surface is made larger than the actual product angle and formed into an obtuse angle, and after forming, a cut is provided between both surfaces to assemble both surfaces and form the forming angle. In order to absorb the difference with the product angle, the conventional slide structure in the mold is no longer necessary, and the purpose of reducing the manufacturing cost of the mold and making the molding work easier is achieved.

[Example] Hereinafter, an example of an automobile trunk trim member and a mold thereof according to the present invention will be described with reference to FIGS. 1 to 9.

In this embodiment, the mold is shown in FIGS. 1 to 4, and the original shape of the trim member formed by this mold is shown in FIG.

The mold is a male mold 1 as shown in Figures 2 to 4.
0. Consists of a structure in which female molds 20 are combined and pressed. As shown in detail in FIG. 1, the male die 10 includes a floor surface forming section 10a and a front surface forming section 1.
0b, side surface forming portion 10c, rear surface forming portion 10
d and a concave groove consisting of the storage convex forming portion 10e. Further, the female mold 20 has a second
As shown in Figures to Figure 4, the floor surface forming part 2
0a, a concave groove consisting of a front surface forming portion 20b, a side surface forming portion 20c, a rear surface forming portion 20d, and a convex groove consisting of a storage convex portion forming portion 20e, and is combined with the male mold 10. ing.

Floor surface forming parts 10a, 2 of such a mold
0a and the rear surface forming portions 10d and 20d define a forming angle θ, which is larger than the actual product angle and is an obtuse angle.

Therefore, in the trim member molded by this mold, the floor surface 1 and the rear surface 4 define the molding angle θ, as shown in FIG. Since it is open on the sides, it is possible to press and cut the mold without the need for a conventional slide structure, and the manufacturing cost of the mold is low and the molding process is easy. Furthermore, since no sliding operation is required, molding efficiency can be improved, and the cost of molding the trim member can also be reduced. Furthermore, since the mold is not provided with a sliding structure, sliding friction is reduced and the durability of the mold is improved.

The original shape of the trim member formed in this way is as shown in FIG. 6, by cutting out a part of the space between the side surface 3 and the rear surface 4 to provide a notch 6, and as shown in FIG. and rear surface 4 are assembled to form a completed product as shown in FIG. In addition, during the cutting, since the cutting piece 7 is shaped to absorb the difference between the forming angle θ and the actual product angle, the trim member has the same shape as the conventional trim member (see comparison of FIGS. 8 and 11).
can be obtained. Also, attach the cut piece 7 to the rear surface 4.
If the folded portion 8 is formed in the shape, there is an advantage that the assembly between the side surface 3 and the rear surface 4 can be strengthened. Further, by assembling the side surface 3 and the rear surface 4, precise attachment is possible by absorbing molding errors in the trim member itself, errors in the mounting portion of the trim member, and the like.

Further, the original shape of the trim member is a semi-finished product as shown in FIG. 6, and can be stacked as shown in FIG. 9, which is convenient for storage, transportation, etc.

[Effects of the invention] As described above, the automobile trunk trim member and the mold thereof according to the present invention, as common to claims 1 and 2, eliminate the need for the conventional slide structure in the mold, and improve the structure of the mold. This has the effect of reducing manufacturing costs and facilitating the shaping work of the trim member. Further, since a sliding operation is not required, the molding efficiency of the trim member is improved and the manufacturing cost of the trim member is reduced.

Further, as claimed in claim 1 alone, various errors can be absorbed during assembly due to the assembly structure of the side surface 3 and the rear surface 4, and precise attachment is possible, and semi-finished assembly with pending assembly is possible. It can be stacked in a state of product, making storage, transportation, etc. convenient.

Furthermore, since the mold is not provided with a sliding structure, the sliding friction is reduced and the durability of the mold is improved.
