ることを特徴とする離型装置。[Claims for Utility Model Registration] A mold is divided into a plurality of mold components that partially contact the molded product, and each mold component is sequentially pushed up by a plurality of push-up members to separate the molded products. In a mold release device that releases the mold in stages from the mold component, between the front and rear side thrust-up members of the plurality of push-up members, the rear-side thrust-up member is thrust up relative to the front-side thrust-up member. A spring member that biases the molded product in the direction is inserted, and the spring force of the spring member is set to be smaller than the mold release resistance of the molded product in the front stage push-up process and larger than the mold release resistance in the rear stage push-up process. A mold release device featuring:
