2. Description of the Related Art Heretofore, various elastic molding dies for producing solid three-dimensionally shaped foods having a complicated shape without score lines, such as chocolate and kamaboko, and various production methods using the same have been proposed. JP-A-62-134707 and JP-A-62-175160 disclose an elastic molding die composed of an elastic film-shaped fixing piece that spreads in a plane continuously to the opening of the die body. Japanese Laid-Open Patent Publication No. 3-142204 discloses an elastic molding die including a die body, a support portion that continuously extends outwardly in a conical shape and a mouthpiece provided on an outer peripheral edge of the cone portion, and An elastic forming type has been proposed in which a supporting ring with a fixing fitting ring is attached to the mouthpiece.

Further, as a method for producing a solid three-dimensionally shaped food using an elastic molding die, Japanese Patent Laid-Open No. 63-31726 discloses that an elastic molding die is filled with a molding raw material, and the molding raw material is solidified, and then elastic. A method of inflating the elastic molding die with a negative pressure on the side opposite to the opening side of the molding die and releasing the solidified molded product, that is, the three-dimensional molded food, is also described in JP-A-1-289474. A method has been proposed in which, after solidification, pressure is applied from the opening side of the elastic molding die to expand the elastic molding die, and the solidified three-dimensional molded food is released from the mold.

When a solid three-dimensional molded food is manufactured using an elastic mold, the elastic mold is mounted on a pallet as described in the above-mentioned JP-A-63-31726 and JP-A-1-289474. It is advantageous to move the entire pallet on the conveyor and perform a series of operations such as filling of the forming raw material, solidification, and release. However, in the case of the method of the above-mentioned patent application, since the planar fixing piece continuous to the main body mold is fixed by the upper and lower two pallets having the fixing holes, it is difficult to position the main body mold and the pallet is elastic. There is a problem in that it takes time and effort to fix the molding die, and the elastic molding die tends to shift when it is inflated for releasing. When releasing,
There was a problem that the elastic film-shaped fixing piece was sandwiched between the elastic film-shaped fixing piece and the cup-shaped negative pressure chamber or the pressurizing chamber in close contact with the elastic film-shaped fixing piece, and a cup-shaped mold holder was also required on the opposite side. ..

On the other hand, JP-A-3-142204 discloses an elastic molding in which a support ring with a fixing fitting ring is attached to a mouthpiece provided on the outer peripheral edge of a conical support in order to facilitate fixing. Although a mold has been proposed, a separate pallet for fixing the fitting ring is required to operate it on the conveyor, and one elastic mold is required for each elastic mold as compared with the case where the elastic mold is directly fixed to the pallet. A support ring with a fitting ring must be attached, which is wasteful and time-consuming.
