Problems to be Solved by the Invention However, in such a conventional structure, when the luggage L-Q is stored in the luggage compartment 2 as shown in Fig. or if the luggage is at a height tt, the luggage is placed on the upper edge 2a, then lifted again and carried into the trunk room 2. For this reason, the fabric 1
1 wears out early due to contact with luggage, and
There was a fear that the fabric 11 would peel off from the core material 10, resulting in a decrease in quality.

The present invention has been made in view of the above-mentioned conventional circumstances, and in addition to disposing a pace member made of synthetic resin in areas where the degree of wear is significant, the fabric, that is, the carpet itself, and the base member are molded. To provide a method for manufacturing a carpet molded product for a vehicle, which can obtain a product in which the carpet does not easily peel off from the base member even if frictional force is generated in the carpet by integrating the parts in the process. It is.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention includes attaching a clip member having a U-shaped cross section to the end of the carpet, and protruding the clip member into the molding die. The clip member and the base member covering one side of the carpet and the end portion of the pace member are fitted with the protruding strips and placed in a carveratona mold, and the mold is filled with a molding material. After the molding material hardens, the integrally molded product is removed from the protrusion of the clip member and carried out from the molding die.

For this reason, by fitting the Carpeller with the convex strip of the clip, it is fixed in a predetermined position without being displaced by the pressure generated inside the mold during molding.Next, the molding material is filled into the mold. At the same time, a base member is molded that connects the clip member and one side of the carpet, and an extended part of the base member is formed.Therefore, the extended part is made of the molded material on which the carpet is not overlapped. only the molded part.

After the molded material has hardened, the clip member is removed from the protrusion and carried out of the mold, which is an integrally molded product consisting of the carpet and the base member.

Therefore, the molded product is provided with a part where the carpet is overlapped and an extended part formed only from the molded material, and by placing the extended part in the area where the friction is significant, the carpet Deterioration in quality due to early wear can be avoided. In addition, the clip member is integrally arranged in the molded product, but since the clip member is located at the edge of the carpet, the clip member appears to be placed along the edge of the carpet. Looks like an abandoned mall.

Therefore, by effectively utilizing clip members that are no longer needed after molding is completed, it is possible to improve the custom appearance.

Example An embodiment of the present invention will be described below with reference to the drawings.

That is, as shown in FIG. 2, first, staples 12 are attached to both ends of the carpet 9 which has been cut into a predetermined shape.
and attach the clip member 13. The clip member 13 includes a base 14 located on the rear surface 9 & side of the carpet 9, and a protrusion 16a having a U-shaped cross section provided at the end of the base 14 via a groove 15.

16b, and the tips of the projecting pieces 161L and 16b are in contact with each other under normal conditions. On the other hand, as shown in FIG. , protrusions 21, 21 are provided on the lower mold 19. And the said Carpela) tj,! As shown in Figure 1, the upper and lower molds are 18°1
After opening 9, attach the clip member 1 to the protrusions 21, 21.
3 are fitted together and housed in the lower mold 19, whereby the carpet 9 is held between the protrusions 21 and 21 to prevent it from being displaced by pressure during molding.

At this time, the projections 16a, 16bh of the clip member 13 are pushed open by the insertion of the protruding strip 21 as shown in FIG. It is transformed into. Next, as shown in Figure 5, the upper and lower molds 18 and 19 are combined, and a thermosetting molding material n is filled into the cavity 20 through a gate (not shown), followed by heating and 7FO pressure. As a result, the clip member 13 and the back surface 9 of the carpet 9
A base member 23 extending across the a side is molded, and a carpet molded part having an extension portion 24 provided at the end of the base member is molded. At this time, the projecting pieces 16a and 16b
:f As mentioned above, since it fits into the protrusions 21, 21, the carpet surface 9 of the molding material n melted during heating.
The base member 23 is thus properly formed only on the carpet back surface 9a@. Then, when the molding material n has hardened, the upper and lower molds 18, 19
The carpet 9. is opened, the clip member 13 is removed from the protrusion 21, and the carpet 9. Clip 13. The carpet molded part, which is an integrally molded product composed of the base member 23 and the extension part 24, is carried out from the lower mold 19. Then, as shown in Figure @6, the base 8 (s 14 tar,
Due to the restoring rigidity of the base member, it is corrected horizontally along the base member, and both projecting pieces 16m and 16bt! base 1
Due to the deformation stress of 4, the tips came into contact with each other, and the protrusions 16m and 1
The gap between 6b is closed. For this reason, the protrusion 16jL.

16b is integrated in appearance and looks like a carpet 9.
It gives the impression that it is a molding inserted between the end portion and the extension portion 24. The carpet molded product 25 thus formed is as shown in FIG.
4 is located on the rear upper edge 2a of the trunk room 2, and can be disposed on the inner circumferential wall of the trunk room 2. Then, the extending portion 24 is arranged so that the carpet 9 is not overlapped with the carpet 9.
Since it is composed only of the molded material n, even when luggage is stored in the luggage compartment 2, even if the luggage comes into contact with the rear upper edge 2a of the luggage compartment, it will not easily wear out, and the quality due to wear will be reduced. It is possible to eliminate the decrease in In addition, since the carpet 9 is integrated with the base member 23 by heat curing of the molded material 22, even if the luggage in the trunk room 2 rubs against the carpet 9 due to travel vibrations, the carpet 9 will not be attached to the base member. 23
This prevents further peeling and can reliably prevent deterioration in quality due to peeling.

! 8 and 9 show other embodiments of the present invention,
The carpet 9 side projecting piece 16b of the clip member 13 is provided with a notch 26 at its base end and a lip at its tip gs. In this embodiment, as shown in FIG. 8, the carpet 9 is fixed in a predetermined position by sandwiching the protruding strip 21 between the other protruding piece 9a and the lip n, and the clip member 13 is inserted from the protruding strip 21. When detached, both protruding pieces 16a and 16bh come into contact with each other, and the end of the other protruding piece 16a is hidden by the lip n, as shown in FIG. Therefore, the clip member 13 is not visually determined to be the clip member 13, but the lip n is mistakenly recognized as a linear molding, and the appearance quality can be further improved.

In the above embodiment, injection molding is performed using a sheet-like thermosetting resin, but the invention is not limited to this, and vacuum forming may also be performed by providing a vacuum hole in the lower mold 19. Especially of course.

As described in detail, the present invention involves attaching a clip member to an end of a carpet, and fixing the carpet by fitting the clip member into a protrusion protruding from a molding die. A molding material is filled in the mold to form a base member on one side of the clip and the carpet, and an extended part is formed at the end of the base member to obtain an integrally molded product. Therefore, the carpet is held in a predetermined position by fitting with the protrusion of the clip, without being displaced by the pressure generated in the mold during molding, and an integrally molded product with the carpet placed in the proper position can be obtained. At the same time, it is possible to improve the appearance characteristics by effectively utilizing a clip member that is not needed after molding and is mistakenly recognized as a molding member in appearance.

In addition, since the integrally molded product is provided with an extension made of only the molded material, by arranging the extension in a location where the degree of wear is significant, it is possible to reduce the quality of the carpet due to early wear. In addition, as the molding material hardens, the carpet firmly adheres to the base member, thereby reliably preventing deterioration in quality due to peeling of the carpet.
