- 成形型の内面に一体成形用部材を係止させておき、該一体成形用部材を該成形型内での樹脂原料の発泡成形時に発泡樹脂と一体化させ、その後、成形体を脱型する樹脂発泡体の成形方法において、
該一体成形用部材を成形型の内面に沿ってスライドさせることにより該成形型に係止させるようにした成形方法であって、
該一体成形用部材は、該成形型の内面に設けられた係止用突起に係合して該一体成形用部材を該成形型の内面に保持させておくための凹部を備えており、
該係止用突起は細い根元部と拡大した頭部とを有しており、
該凹部は、該根元部が係合する狭幅部と、該頭部が係合する広幅部と、該頭部の通過用の大穴部とを有しており、
該一体成形用部材の成形型内面への取付に際しては、該頭部が該大穴部に差し込まれ、次いで一体成形用部材が前記スライドされることにより該係止用突起が該大穴部から該狭幅部及び広幅部に入り込み、
該成形型の内面に該一体成形用部材の端部を受け入れるポケット部が設けられており、該一体成形用部材は前記スライドによりその端部が該ポケット部に嵌合されることを特徴とする樹脂発泡体の成形方法。 - 請求項1において、脱型に際しては係止用突起が該狭幅部及び広幅部から大穴部に移動するように成形体を前記スライドと反対方向に移動させることを特徴とする樹脂発泡体の成形方法。
- 請求項1又は2において、該狭幅部及び広幅部は該大穴部から直線状に延出していることを特徴とする樹脂発泡体の成形方法。
- 請求項1ないし3のいずれか1項において、複数個の前記凹部が設けられており、各凹部の大穴部から狭幅部及び広幅部が延出する方向が一直線上に且つ同方向に位置することを特徴とする樹脂発泡体の成形方法。
- 請求項1ないし3のいずれか1項において、複数個の前記凹部が設けられており、各凹部の大穴部から狭幅部及び広幅部が延出する方向が平行且つ同方向であることを特徴とする樹脂発泡体の成形方法。
- 請求項1ないし5のいずれか1項において、該樹脂発泡体はシートパッドであることを特徴とする樹脂発泡体の成形方法。
