1. A die molding surface treatment device comprising:
a moving body including a portion that is disposed between a pair of dies that are arrayed in a horizontal direction, with molding surfaces of the dies opposing one another;
a driving mechanism that reciprocatingly moves the moving body in a direction that is orthogonal to an opposing direction of the pair of dies in a device plan view and that is along a device floor surface;
a treatment function portion provided at the moving body, the treatment function portion performing at least one of a treatment of air-blowing the molding surfaces of the pair of dies or a treatment of applying a parting agent to the molding surfaces of the pair of dies; and
a cleaning implement attached to a lower portion of the moving body, the cleaning implement reciprocatingly moving together with the moving body and sweeping the device floor surface.
