れている。In FIGS. 1A to 1C, reference numeral 2 is a skin material of the rear parcel shelf 1. As the skin material 2, it is desirable to use a high density nonwoven fabric made of fibers such as polyethylene terephthalate. As a result, molding can be performed by a method common to thermoplastic resins, and sufficient air permeability can be maintained. Reference numerals 3 and 4 denote an upper mold and a lower mold for manufacturing a skin-integrated molded product according to the present invention, and the upper mold 3 has a recess 3A having a shape corresponding to the lower mold 4.
And a locking needle 5 for holding the skin material 2 in a stretched state is provided around the recess 3A. Further, one lower die 4 has a pin 6 for forming a hole in the base body 1A of the drafter grill 1 formed as shown in (D) through the steps shown in (B) and (C) with a resin material. It is elastically held by a spring 7 so that it can move back and forth.

As the base molding material 8, for example, polypropylene, which is a thermoplastic resin having excellent mechanical properties such as rigidity, bending fatigue resistance, heat resistance, and a melting point of about 180 ° C., is suitable.

料8を伸延させていく。Therefore, first, as shown in (A), a sufficient amount of the base molding material 8 to form the rear parcel shelf base 1A on the lower mold upper surface 4A is supplied, and at least the skin material 2 is supplied.
Also, the base molding material 8 is kept at a temperature at which it can be molded. Then, as shown in (B), the upper mold 3 is gradually pushed down in conformity with the lower mold 4, the free end of the pin 6 is brought into contact with the skin material 2, and the skin material is lifted and maintained, while the skin material 2
The base molding material 8 is extended into a space 9 formed between the lower mold upper surface 4A and the lower mold upper surface 4A.

することができる。In this case, the spring force of the spring 7 is the upper mold 3
When the upper skin 3 further descends after the skin material 2 held on the upper mold 3 comes into contact with the tip of the pin 6 as it descends, at least the lower surface of the display material 2 and the upper surface 4A of the lower mold 4 are descended. It suffices that the skin material 2 can be pushed upward so that a space 9 is formed between the skin material 2 and. Thus, when the upper die 3 has finished descending onto the lower die upper surface 4A as shown in (C), the pin 6 is in a form of holding the skin material 2 between the upper die 3 and the lower surface of the concave portion 3A, The base molding material 8 is spread between the upper mold 3 and the lower mold 4 in a substantially uniform state except for the pin 6 and molded as it is, and at the same time, the skin 2 and the rear parcel shelf base 1A are integrated by the anchor effect. Can be converted.

皮一体型の成形部品を得ることができる。Therefore, after this, the molded product which has finished molding and is cooled is taken out by separating the upper mold 3 and the lower mold 4, whereby the skin material 2 and the base body 1A are integrated as shown in FIG. It is possible to obtain the rear parcel shelf 1 in which the ventilation holes 10 are formed in the base body 1A, and the ventilation holes are formed in the base body in the conventional manner, and then the skin material is attached to the base body using an adhesive. A skin-integrated type molded component can be obtained without the step of installing.

けの深さがあればよい。In the embodiment described above, as one basic example, one rear parcel shelf 1 is provided with one vent hole 10. However, as shown in FIG.
It is needless to say that the number of 0 may be plural, and it is not necessary to attach the skin material 2 after molding the base body 1A regardless of the number of the vent holes 10. Further, in the above-mentioned example, the upper mold is provided with a concave portion, and the lower mold is processed in such a manner that the lower mold is fitted into the concave mold. This is for forming a space for spreading the base forming material 8 between the upper surface of the lower mold and the depth of the recess formed in the upper mold need not be particularly deep. It suffices if the pin has a sufficient depth to achieve the above purpose in cooperation with the pin.
