1. A work molding system for producing a molded article by molding a work, the system comprising:
a work forming device configured to form a work;
a molding device configured to perform molding of a formed work formed by the work forming device; and
a conveying device configured to convey the formed work formed by the work forming device from the work forming device to the molding device, wherein
the conveying device includes a holding member for holding the formed work formed by the work forming device and a molded article molded from the formed work by the molding device, and a movement mechanism for moving the holding member,
the holding member includes a work holding part configured to hold and heat the formed work formed by the work forming device, and a molded article holding part configured to hold the molded article molded from the formed work by the molding device,
the work holding part is composed of a work holding mechanism and a heater attached to the work holding mechanism,
the formed work is vacuum-molded using a movable mold of the molding device,
as a result of resin being supplied into a cavity having a recessed shape formed between the movable mold and a fixed mold, resin injection molding is performed on the front surface of the formed work that has been vacuum-molded using the movable mold,
the work holding mechanism includes a body part, the body part has a configuration in which a base member and an elastic member composed of an elastic material are layered, and
the elastic member being made of a material having heat resistance.
