A method for manufacturing the automobile interior part 1 will be described.
First, the base material 10 and the engaging convex portion 20 are molded by an injection molding method or the like.

  Next, the skin 30 is molded by an insert molding method. Specifically, as shown in FIG. 4, the base material 10 is mounted on the mold 60, the mold 62 is brought close to the mold 60 from above the base material 10, and the mold 60 and the mold 62 are clamped. Then, the molten thermoplastic resin 35 is injected and filled into the cavity 65 formed inside the mold 60 and the mold 62, and the outer skin 30 is molded by curing the thermoplastic resin 35 (injection molding method). The outer skin 30 is obtained by curing the thermoplastic resin 35.

Here, a core portion 61 that matches the shape of the substrate 10 is formed on the mold 60. On the other hand, a cavity 63 corresponding to the core 61 is formed on the mold 62, and a protrusion 64 is formed on the peripheral edge of the cavity 63. When mounting the base material 10 on the mold 60, the core portion 61 is fitted on the back side of the base material 10. When the mold 60 and the mold 62 are clamped, the core portion 61 and the base material 10 are fitted into the cavity portion 63. The volume of the cavity portion 63 is larger than the volume of the core portion 61, and a cavity 65 is formed on the front side of the substrate 10, and the cavity 65 extends along the surface on the front side of the substrate 10. Further, the cavity 65 extends outward from the bent portion between the upper upper end portion 12 and the flange portion 13 of the base material 10 and is provided in parallel with the die matching surface. The protruding end of the protrusion 64 is in contact with the mold 60 on the outside of the substrate 10. The cavity 65 corresponds to the skin 30, and the protrusion 64 corresponds to the engagement hole 31. If the molds 60 and 62 as shown in FIG. 4 are used, the skin 30 is formed so as to cover the front side surfaces of the main body 11 and the upper upper end 12, and a part of the skin 30 is composed of the upper upper end 12 and the flange. It is branched and formed from the bent part between the parts 13.
In addition, the molding method of the base material 10 and the skin 30 may be an in-mold molding method or a two-color molding method.

Next, the molds 60 and 62 are opened, and the base material 10 and the skin 30 are removed.
Next, as shown in FIG. 5, a portion of the skin 30 separated from the bent portion between the upper upper end portion 12 and the flange portion 13 is bonded to the surface on the front side (the vehicle compartment outside) of the flange portion 13. While sticking by heat welding or the like (note that it is not necessary to perform adhesion or heat welding), the portion is pulled and folded back to the back side of the flange portion 13, and the engaging convex portion 20 is hooked on the engaging hole 31. Stop. And the skin 30 is stuck on the surface of the back side (vehicle compartment side) of the flange part 13 by an adhesive agent or heat welding (it is not necessary to adhere | attach or heat-weld).

Next, the attachment hole 14 is drilled in the skin 30 and the flange portion 13.
Next, the nail | claw 41 of the rubber member 40 is hooked and stopped in the attachment hole 14, and the rubber member 40 is attached to the surface on the front side of the flange part 13. FIG.

  The automobile interior part 1 and the manufacturing method thereof as described above provide the following operational effects.

(1) Since the engagement convex part 20 and the base material 10 are integrally molded, it is possible to suppress the engagement convex part 20 from dropping off and to prevent the skin 30 from peeling off. Moreover, since one part is comprised from the engagement convex part 20 and the base material 10, the reduction | decrease of the number of parts of the automotive interior goods 1 can also be aimed at. Since the engaging convex part 20 is shape | molded in the case of shaping | molding of the base material 10, while being able to aim at the reduction of the manufacturing process of the motor vehicle interior goods 1, the workability | operativity at the time of providing the engaging convex part 20 is also improved.

(2) Since the skin 30 is folded back to the back side of the flange portion 13, the skin 30 is pulled downward on the back side of the flange portion 13. Since the longitudinal direction of the engagement convex part 20 and the engagement hole 31 is orthogonal to the tension direction, the engagement hole 31 does not expand by tension. Therefore, it is possible to prevent the engagement convex portion 20 and the engagement hole 31 from coming off.

(3) Since the engaging convex portion 20 is provided so as to avoid the surface of the flange portion 13 outside the passenger compartment, the rubber member 40 is stably attached to the flange portion 13.

(4) Since the engaging convex portion 20 is formed on the flange portion 13, the rigidity of the flange portion 13 can be increased by the engaging convex portion 20. Since the engagement convex portion 20 and the attachment hole 14 overlap each other, the engagement convex portion 20 can suppress a decrease in rigidity of the flange portion 13 due to the attachment hole 14.

(5) Since the engaging hole 31 is formed by the protrusion 64 of the mold 62 when the skin 30 is molded, the position and size of the engaging hole 31 are compared with the case where the hole is formed by the drilling operation. High accuracy.

(6) The mating surfaces of the dies 60 and 62 are not on the surface of the skin 30 but on the edge of the skin 30 (see FIG. 4), and the skin 30 wraps around the back side of the flange portion 13, Parting line is hidden. Also, no burr removal work is required.
