To provide a foam molding product that can suppress tearing around through holes on a side face, a manufacturing method for the foam molding product, and a molding form that can be used optimally in the manufacturing method for the foam molding product.SOLUTION: A foam molding product 1 has a pad material 10 and a first member 11. A side face of the pad material 10 has such a shape that a front surface side of the foam molding product 1 protrudes outward more than a back surface side of the foam molding product 1, and has an unfinished through hole 104 having a chipped portion 104a formed such that at least a part of a peripheral wall of the through hole 12 on the front surface side of the foam molding product 1 is chipped. The foam molding product 1 has a through hole 12 formed on a side face by attaching the first member 11 to the chipped portion 104a of the pad material 10. A molding form 2 for molding the pad material 10 having the above shape does not make a portion of a lower mold 21 side of an unfinished through hole molding section 233 into an undercut shape.SELECTED DRAWING: Figure 1

    【課題】側面の貫通穴周囲の破れを抑制可能な発泡成形品、当該発泡成形品の製造方法、また、当該発泡成形品の製造方法に好適に用いることが可能な成形型を提供する。【解決手段】発泡成形品1は、パッド材10と第1部材11とを有する。パッド材10の側面は、発泡成形品1の裏面側よりも発泡成形品1の表面側の方が外側に張り出した形状を呈しており、貫通穴12の周壁のうち発泡成形品1の表面側の少なくとも一部が欠けた形状となるように形成された欠け部位104aを備える未完成貫通穴104を有している。発泡成形品1は、パッド材10の欠け部位104aに第1部材11が取り付けられることにより、側面に貫通穴12が形成される。上記形状を呈するパッド材10を成形するための成形型2は、未完成貫通穴成形部233の下型21側の部分がアンダーカット形状になることがない。【選択図】図1
