In this method of forming a different hardness sheet pad, as shown in FIG. 4, the foam 80 for forming the side portion of the seat pad is set in the lower mold 82 in advance. These foams 80 are foams that have finished foaming with a foaming agent different from the foaming agent that constitutes the main portion of the seat pad, and are foams that are harder than the foams that configure the main portion. The foaming agent 88 that constitutes the main portion of the seat pad is injected into the cavity 86 formed by the lower mold 82 in which the foam 80 is set and the upper mold 84, and foamed to manufacture the different hardness seat pad. ..

成形が完了する。When the foaming agent 26 is foamed in this state, the foaming agent 26 foams and the cavity 22 becomes full. Further, the foaming agent 26 continues foaming and tries to penetrate into the slab material 16. Here, the displacement control valve 20 is opened, and
When the foaming gas is released from the exhaust pipe 18 as shown by the arrow B in FIG. 2B, the foaming agent 26 enters the slab material 16 as shown by the arrow C in FIG. 2B. Slab material 1
The foaming agent 26 that has penetrated into the inside 6 is crushed at the same time and becomes entangled with the slab material 16 and becomes hard. As a result, a hardened layer 28 as an impregnated layer that is harder than the main portion of the seat pad is formed on the outer peripheral portion of the slab material 16. Therefore, upper mold 1
When the seat pad to be the product is taken out from the molding die 10 after separating the lower mold 11 from the mold 2, the slab having the hardened layer 28 formed on the portion of the seat pad made of the main foam which is desired to have different hardness. The material 16 remains, and the forming of the different hardness sheet pad is completed.

Since the soft foam forming the main part of the seat pad is interposed between the seat pad and the sheet 4, the tactile sensation as a product is improved as compared with the conventional different hardness seat pad in which the foam of different hardness contacts the skin. In addition, in this embodiment, compared with a foam having a different hardness (for example, urethane having a density of 0.025 to 0.045 g / cm 3 ), it is ultralight (for example, a density of 0.01 to 0.02 g / cm 3 ).
Since the slab material of is used, weight reduction can be achieved. Further, in this embodiment, the control device controls the displacement control valve 20.
By adjusting the displacement of the foaming gas,
The thickness of the hardened layer 28 can be changed, and the hardness of the hardened layer 28 can be arbitrarily set.

In this case, however, the foaming agent flows out from the vent hole and the vent hole is discharged. The vent hole may need to be cleaned as it may be blocked. On the other hand, in this embodiment, the vent hole can be eliminated and the cleaning work of the vent hole is eliminated, so that the work efficiency is improved.
