In the cross-sectional view of FIG. 1, 1 is an elastic mold made of rubber latex, 2 is a holder for supporting the end of the elastic mold, which forms an annular shape. Reference numeral 3 is a nozzle for introducing chocolate into the elastic molding die, and the positive (+) electrode of the static electricity generator 6 is connected to this nozzle 3. Reference numeral 4 is an opening / closing valve for filling molten chocolate, and 4'is a storage tank provided with a pressure pump. Further, 5 is a metal cylinder surrounding the elastic mold 1, to which the negative (-) electrode of the static electricity generator 6 is connected. The voltage applied to the electrodes was 60 KV.

Is opened and ejected from the injection nozzle 3. At this time valve 4
Is opened and closed to intermittently eject molten chocolate from the nozzle 3. The molten chocolate mass discharged from the injection nozzle 3 is positively (+) charged. On the other hand, since the electrically insulating elastic mold 1 is in the electric field of the charged metal cylinder 5,
The inner surface of this elastic mold is negatively (-) charged. Therefore, the injected molten chocolate mass having a positive (+) charge is first attracted to the inner wall of the elastic mold having a negative (-) charge, adheres to the entire inner wall of the elastic mold, and is applied there. Form a surface. For this reason, the molten chocolate penetrates to the minute recesses of the elastic mold, and no air pockets occur,
Every corner of the elastic mold is filled.

As shown in the figure, connect the release cup 7 to the holder 2,
Further, a mounting table 9 which can be moved downward is installed. Then, by injecting air from the air pressure inlet 8 of the release cup 7 to pressurize the inside of the release cup, the elastic mold 1 is pressed from the outside, the molded chocolate A is pushed out of the elastic mold, and the mounting table 9 is placed. Move to. Thus, a chocolate molded product of desired design with a good surface appearance is obtained.
