金型の底面部を構成するボトムモールド上にアウトソール原料を注入し、このアウトソール原料を加硫しながらダミーモールドで加圧成形して半加硫アウトソールを形成し、該半加硫アウトソールに前記ダミーモールドを押し付けた状態で当該ダミーモールドの前記半加硫アウトソールとの界面の一部に所定量の気体を導入し、その直後に、前記押し付けた状態を解除して前記ダミーモールドを前記半加硫アウトソールから脱離し、前記半加硫アウトソール上にミッドソール原料を注入して、このミッドソール原料と前記半加硫アウトソールとを加硫しながら前記靴のアッパーが装着されたラストモールドで加圧することで前記ミッドソールを成形しながら当該ミッドソールと前記アウトソール及び前記アッパーとを接合するようにしたことを特徴とする靴底の製造方法。 - 請求項1において、前記ミッドソールと前記アウトソール及び前記アッパーとを接合した後、前記アウトソールと前記ボトムモールドとの界面の一部に所定量の気体を導入し、その直後に前記アウトソールから前記ボトムモールドを脱離させるようにしたことを特徴とする靴底の製造方法。
- 請求項1又は2において、少なくとも前記半加硫アウトソールと前記ダミーモールドとの境界に導入する気体を、前記金型と同一温度に加熱するようにしたことを特徴とする靴底の製造方法。
- 請求項1〜3の何れかにおいて、前記アウトソールの前記ミッドソール側の面には凹部が形成されており、該凹部の開口縁部がR形状となるようにしたことを特徴とする靴底の製造方法。
