Abstract

PURPOSE:To retain the handling of a carpet in some degree under a high pressure upon molding stampable resin material. CONSTITUTION:In a mold 1 for molding a carpet laminate, in which a stampable resin material 14 and a skin fiber layer 13 are integrated by pressure molding, emboss, having a depth enough to transfer the configuration of embossing, is accomplished on the skin fiber layer 13.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a mold for molding a carpet laminate.

As a carpet laminate, there is, for example, an automobile floor carpet disclosed in Japanese Patent Laid-Open No. 4-176742. As shown in FIG. 5, the carpet has a skin fiber layer 40, a backing layer 41 laminated on the back surface of the skin fiber layer 40 and mainly made of a thermoplastic resin, and a stampable resin material fixed to the back surface of the backing layer 41. And 42. Then, as shown in FIG. 5, this conventional carpet is integrally molded by compression between the upper mold 30 and the lower mold 31. At this time, as shown in FIG. 6, the contact surface of the upper mold 30 with the surface fiber layer 40 is provided with a shallow groove 30a for preventing slippage with the surface fiber layer 40.

[0003]

However, the carpet laminate integrally molded by using the above-mentioned conventional molding die has a problem that the carpet is severely collapsed and the texture of the carpet is impaired. This must be molded at a pressure of a few kgf / cm ² (or tens of kgf / cm ² ) or less to prevent the carpet from falling over, but the stampable resin material 4
The molding pressure of 2 is higher than the above-mentioned hair fall prevention pressure 15
This is because 0 to 250 kgf / cm ^{2 is} required, so that the surface of the surface fiber layer 40 after molding becomes a glossy plastic shape, and the texture of the carpet is impaired.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a mold for molding a carpet laminate which can hold a carpet to some extent even under a high pressure at the time of molding a stampable resin material. It is in.

[0005]

In order to achieve the above-mentioned object, the present invention provides a carpet laminate molding die in which a stampable resin material and a surface fiber layer are integrally molded by pressure molding. It is characterized in that the contact side die is provided with a grain having a depth sufficient to transfer the grain shape to the skin fiber layer after molding.

[0006]

In the present invention, in which the embosses having a sufficient depth are engraved, the embosses are transferred to the skin fiber layer after molding, so that the light impinging on the surface of the skin fiber layer is irregularly reflected and the surface gloss is lost, and the texture of the carpet becomes Can be reduced.

[0007]

1 to 3 show a mold 1 as a first embodiment of the present invention. The mold 1 comprises an upper mold 11 and a lower mold 12. The lower mold 12 is brought into contact with the surface of the skin fiber layer 13 and the back surface of the skin fiber layer 13 is laminated with stampable resin materials 14 and 14. The carpet laminate 10 can be obtained by performing pressure molding between the upper mold 11 and the lower mold 12. In this mold 1, the lower mold 12 is a mold on the contact side of the skin fiber layer 13, and the contact surface 12a is deep enough to transfer the grain shape to the skin fiber layer 13 after molding. A mountain-shaped grain 15 having a valley portion 15a is formed. The grain 15 is engraved by plastic molding in the same manner as the usual grain formation.

In this carpet laminate 10 formed by the mold 1, the shape of the grain 15 is transferred to the surface of the surface fiber layer 13, the light impinging on the surface is irregularly reflected, and the gloss of the surface is lost. It is possible to reduce the loss of texture. Further, the mold 1 can reduce the hair fall of the skin fiber layer 13 at the rib forming portion even when the carpet laminate 10 having the rib structure is formed, and the hair fall unevenness due to the sink of the resin is not noticeable. Can be one.

FIG. 4 shows another grain 16. This grain 16
Is formed into a trapezoidal shape having a valley portion 16a having a depth sufficient to transfer the embossed shape to the molded skin fiber layer 13, and a normal embossed surface 16b having a shallow groove is formed on the top thereof. This grain 16 is the skin fiber layer 1 of the lower mold 12 described above.
3 is engraved on the contact surface 12a, and the carpet laminate 10 is molded with the mold 1 using the lower mold 12, whereby the shape of the grain 16 is similar to that described above.
It is transferred to No. 3 to obtain a matte state due to irregular reflection, and it is possible to reduce the loss of the texture of the carpet.
The same effect as 5 is achieved.

[0010]

As described above, according to the present invention, it is possible to integrally form a carpet laminated body that moderates the hair fall of the skin fiber layer and maintains the texture as a carpet to some extent by pressure molding. The number of steps can be reduced to reduce the cost, and a carpet laminate molding die suitable for mass production can be provided.
