時に二次的に行うようにしてもよい。In order to manufacture an automobile interior material using the injection-molding die configured as described above, first, between the upper mold (3) and the lower mold (2) in the mold opened state as shown in FIG. First, the ornament member (11) made of fabric is intervened, and its end edge is locked to the needle-like projection (6) of the slide core (7) in the raised position and set on the lower mold (2), Next, a skin material (12) having a cushion layer (12b) such as polypropylene foam laminated on the lower surface of the synthetic resin substrate (12a) is usually set to a size such that the lower mold (2) is substantially entirely covered. Set by law. Then, the upper die (3) is lowered and the ornament member (11) is attached to the lower end of the pressing portion (8).
The end edge of is pressed against the slide core (7), and in this state, as shown in FIG. 2, the ornament member (11) and the lower mold (2) and the skin material ( The synthetic resin molding material (21a) is injected and injected into the cavity (4) between the lower die (2) and the portion of the ornamental member (11) not overlapped with each other without opening the die after semi-curing. As shown in FIG. 3, the slide core (7) is slightly lowered to form a void (13) on the back side of the parting position between the ornament member (11) and the skin material (12), and this void (13) is also formed. The synthetic resin molding material (21b) is injected and injected from an injection gate (not shown) to mold a molding base material (21) integrated with the synthetic resin molding material (21a), and at the same time, an ornament member (11) is formed on the surface thereof. After covering with the skin material (12) and removing the mold, the skin material (12) The portion of the ornamental member (11) that covers the ornament member (11) is the needle-like protrusion (6).
The surface of the molded base material (21) is peeled off by a normal peeling cutting method using a cutter or the like from the boundary portion as a mark attached by pressing with the slide core (7) and the ornament member (11) and the skin material. The fourth separated by (12)
The product shall be as shown in the figure. It should be noted that the synthetic resin molding material is temporarily injected only into the cavity portion on the ornament member (11) side, and the injection into the cavity portion on the side where the ornament member (11) is not mounted is injected into the void (13). At the same time, it may be performed secondarily.
