Abstract:
1. A molded product production device adapted to be used for producing a molded body by compression molding a molding material, comprising: a molding die having an inner circumferential surface defining a cavity with upper and lower openings, the cavity into which the molding material is to be filled; a lower punch provided so as to be inserted into the cavity from the lower opening thereof, so that the lower punch is vertically movable in the cavity, the lower punch having a lower punch surface and a lower punch release agent holding portion which is provided at a lower side of the lower punch surface and capable of holding a release agent; an upper punch provided so as to be inserted into the cavity from the upper opening thereof, so that the upper punch is vertically movable, the upper punch having an upper punch surface; and a lower punch release agent supply means which supplies the release agent to the lower punch release agent holding portion by applying a release agent solution in which the release agent is dissolved onto the lower punch release agent holding portion when the lower punch release agent holding portion is exposed outside the cavity, so that the release agent solution is applied to the inner circumferential surface of the cavity when the lower punch release agent holding portion is moved into the cavity.
