Abstract
A foaming die device is provided, which has a closure element rotatably provided therein. The foaming die device allows a three-dimensional trim cover assembly with an opening defined therein to be placed therein and also allows a liquid foaming agent to be injected into an inside of so placed trim cover assembly for foaming operation. In operation, when the trim cover assembly is placed in foaming die device prior to the foaming operation, the closure element is able to be rotated toward and easily inserted in the opening to prevent leakage of the liquid foaming agent therethrough, whereas, when the trim cover assembly is taken out from the foaming die device subsequent to the foaming operation, the closure element is able to be rotated and easily removed from that opening.
