The present invention provides a foaming mold for manufacturing a steering wheel. The foaming mold includes an upper disk and a lower disk coupled to the upper disk to carry out foaming of an object to be foamed, wherein the upper disk comprises the same material and is integrated as a whole including the portion with which the object to be foamed is in contact, the material of the upper disk and that of the lower disk are the same, and each of the upper disk and the lower disk has a cooling hole for cooling the object to be foamed. Herein, the cooling hole preferably perforates to the site where the object to be foamed is positioned. The present invention also provides a foaming method which includes allowing a cooling fluid to pass through the cooling hole to carry out cooling of the object to be foamed.

    스티어링 휠 제작용 발포 금형으로서, 상원판과, 상원판과 결합하여 발포 대상에 대한 발포 금형을 수행하기 위한 하원판을 구비하며, 상원판은 발포 대상이 접하는 부분을 포함하여 전체적으로 일체화되어 동일한 소재로 구성되고, 하원판은 발포 대상이 접하는 부분을 포함하여 전체적으로 일체화되어 동일한 소재로 구성되며, 상원판의 소재 및 상기 하원판의 소재는 서로 동일하고, 상원판 및 하원판 각각에는 발포 대상에 대한 냉각을 위한 냉각 구멍이 형성되어 있는, 발포 금형이 개시된다. 이때, 냉각 구멍은 발포 대상이 위치하는 개소를 통과하는 것이 바람직하다. 또한, 발포 금형에 구비된 냉각 구멍에 냉각 유체를 유통시킴으로써, 발포 대상에 대한 냉각을 수행하는, 발포 금형 방법이 개시된다.
