An upper mold device includes an upper mold mechanism, a gas storage unit adapted to store a processing gas, gas intake and exhaust units, and a negative pressure source. The upper mold mechanism includes a seal cover that is adapted to connected to and cooperate with a lower mold device to define a processing section therebetween, and gas inlet and outlet connectors that are mounted to the seal cover. The gas intake unit is in fluid communication with the gas storage unit and the gas inlet connector. The gas exhaust unit is in fluid communication with the gas outlet connector. The negative pressure source is in fluid communication with the gas exhaust unit, and extracts air that is in the processing section via the gas exhaust unit when activated, such that the processing gas flows into the processing section via the gas intake unit.

A thermoforming device performs a heating process of radiationally heating a resin film to a predetermined temperature by a radiation heater and a bonding process of bonding the radiationally heated resin film to a pulp mold set on a base. The thermoforming device includes a vacuum pump to evacuate a space between the pulp mold and the resin film to bring the resin film to be in close contact with the pulp mold in the bonding process. The radiation heater is changeable in its distance to the resin film between a first heating position to perform radiation heating of the resin film in the heating process and a second heating position to perform radiation heating of the resin film in the bonding process.

The present invention relates to a product forming method, a product, and a shoe. The product forming method comprises the following steps: (1) placing a film on a bottom mold, and fixing the film between the bottom mold and a middle frame; (2) placing an outer housing material on the film, and suctioning the film, so that the film is internally recessed in the direction of the bottom mold, and then performing first curing molding to obtain a molded outer housing; and (3) placing an inner liner material on the molded outer housing, performing second curing molding to obtain a molded inner liner, and demolding to obtain the product.
