Summary:To provide a mold producing apparatus that suppresses pressure fluctuation of an injection pot.SOLUTION: A molding producing apparatus (1) according to one embodiment of the present invention includes: an injection pot (2); a lid member (60); and an injection air supply unit (65b) by which foamed and kneaded material in the injection pot (2) is pressed by compressed air and injected from an injection port. The lid member (60) is provided with a seal body (61) that is brought into close contact with the inner peripheral surface of the injection pot (2) by its being deformed by entry of a fluid under pressure during the pressing of the foamed and kneaded material.SELECTED DRAWING: Figure 1 【課題】射出釜の圧力変動を抑えた鋳型造型装置を提供する。【解決手段】本発明の一形態の鋳型造型装置（１）は、射出釜（２）と、蓋部材（６０）と、射出釜（２）内の発泡混練物を圧縮空気により押圧して射出口から射出させる射出用空気供給部（６５ｂ）とを備え、蓋部材（６０）には、前記押圧の際に流体の圧入により変形して射出釜（２）内の内周面に密着するシール体（６１）が設けられている。【選択図】図１
