させる一体発泡法等がある。As a method for producing a urethane foam molded article, there are:
There is an integral foaming method in which a core material having the rigidity required as an automobile interior component and a skin material for forming a design surface are set in a foaming mold, a polyol component and an isocyanate component are injected, and a foam layer is formed. .

の発泡不良が発生する。In the urethane foam molded article obtained by the above method, when a polyol component and an isocyanate component are injected into a foaming mold between a core material and a skin material, the core material is increased as the reaction proceeds. The space between the core material and the skin material is filled with urethane. However, when the shape of the molded product is formed only with a smooth curved surface or flat surface, there is no particular problem,
In the case of the vertical wall shape, when the urethane flows through the vertical wall shape portion, gas is injected thereinto, and the flow distance of the urethane in the vertical wall shape portion becomes long, so that foaming defects such as voids occur.

する。In order to eliminate the above-mentioned defective foaming, it is necessary to take measures such as changing the shape of the standing wall shape or eliminating the core material of the standing wall shape portion. However, a design change such as a change in the shape of the standing wall greatly affects the shape as a design, and thus cannot always be implemented. Further, when the core material of the standing wall-shaped portion is abolished, a problem occurs in that the rigidity of the standing wall-shaped portion after the foam molding is insufficient.

コストの増大の要因になっていた。In other words, when producing a foam molded article having an upright wall shape, there is no effective method for suppressing the occurrence of foaming defects, and there has hitherto been a method of injecting urethane, adjusting the urethane injection amount or the foaming mold temperature. Thus, the so-called molding conditions have been adjusted to suppress the occurrence of defective foaming. Also,
When the core material is an olefin material such as polypropylene, a primer is applied to the core material or a flame treatment of the core material is performed to impart adhesion between the urethane and the core material. This requires a process for imparting properties, which has been a factor in increasing the manufacturing cost.

できるので、製造コストの低減にもつながる。When the core material is an olefin material such as polypropylene, a primer is applied to the core material or a flame treatment or the like is performed on the core material in order to impart adhesiveness between the urethane and the core material. However, by providing a hole or groove shape in the core material, the urethane of the portion becomes a continuous shape with the core material sandwiched therebetween, and the core material and the urethane do not separate, so the step of imparting adhesiveness to the portion is performed. Since it can be omitted, the manufacturing cost can be reduced.

= A shape having a cross-sectional shape of 50 mm or more. In the case of such a shape, the shape of the core material 3 becomes the wall shape 8 as shown in FIG. 1, and there is a problem that when urethane flows, gas is easily introduced and the flow distance becomes long. Therefore, in the present invention, a hole or a groove-shaped portion for facilitating the flow of urethane is provided in this portion.

In the case of an olefin-based material), a primer is applied to the core material or a flame treatment is applied to the core material to impart adhesiveness. However, in the embodiment of the present invention, since the urethane of the relevant portion is connected, the step of imparting adhesiveness can be omitted although only the relevant portion is performed. In particular, when the core material is an olefin-based material such as polypropylene, the primer is applied to the core material or a flame treatment is applied to the core material in order to impart adhesiveness to the core material and urethane. However, in the embodiment of the present invention, this processing can be omitted, although partially.
