る。FIG. 1 is a conceptual view showing the whole of a conventional apparatus used in the present invention. A panda-shaped elastic molding die 1 having fine irregularities for producing a decorative product is mounted on a driving source such as a motor (not shown). ) So as to be replaceable with the endless conveyor belt 3 wound around the pulley 2. Conveyor belt 3
In the filling step A, the filling pressure chamber 5 is raised in the direction of the arrow by a vertical movement device (not shown) when the conveyor belt 3 is stopped in the filling step A.
The elastic molding die suspended from the conveyor belt 3 is fitted in a close contact state from below. After the fitting, the inside of the pressure chamber 5 is set to a negative pressure by the pressure control device 4, so that the outside air is sucked from the opening 9 on the upper part of the elastic molding die 1 and expanded, and the temperature and viscosity are adjusted in advance by tempering. A predetermined amount of the fluidized chocolate 6 as the fluidized filling is discharged from the storage tank 7 into the filling portion 8 of the elastic mold 1 by a nozzle via a metering device (not shown). Next, the filling pressure chamber 5 is returned to the atmospheric pressure, the elastic molding die 1 is contracted to the original shape, the pressure chamber is lowered by the vertical movement device, and the same die 1 is vibrated by the vibrator 10 while moving the conveyor belt 3, The chocolate in the mold is solidified by being immersed in the cooling tunnel 11 as the solidification step B for a predetermined time. Further, the elastic molding die 1 moves to the mold releasing step C, and the releasing pressure chamber 12 is lowered in the direction of the arrow by an up-down moving device (not shown) to fit the elastic molding die 1 from above into a close contact state. . In this state, the pressure in the mold release pressure chamber 12 is reduced to a negative pressure by the pressure control device 13 so that air is introduced from the opening 9 of the mold 1 to expand the mold.
0 falls on the conveyor 15 and the product is collected by the product collection container 16. The elastic mold 1 after releasing is subjected to a preheating step D
After the chocolate fixed as a residue is blown off or blown by blowing hot air into the mold and melted at the same time, the interior of the mold is made substantially the same as the chocolate discharge temperature in the filling step A, so that the decoration product To maintain a good, glossy quality.

To stop between the release pressure chamber 12 and the fitting chamber 25, and to move the pressure chamber 12 and the fitting chamber 25 up and down by the up and down moving device respectively (FIG. 2), and to provide them at the upper and lower peripheral edges of each chamber. The mold 1 is fitted into the core 25 by closely contacting the sealing materials 18 and 24 to the fixed frame 19 of the belt conveyor (FIG. 3).

く。Next, air is sucked into the release pressure chamber 12 by the pressure control device 13 and air is added to the fitting chamber 25 from a compressor or the like. In this case, the flow of air in the chamber between the release pressure chamber 12 and the fitting chamber shifts from the pipe 25 to the pressure pipe 22, but since the porous core 20 is provided therebetween, the fitting chamber is The pressure difference between the positive pressure state and the negative pressure state is generated between the chamber 25 and the mold release pressure, and the elastic mold 1 expands and is joined along the inner surface of the core 20. In this state, the chocolate molded product 30 as a solidified filler is peeled to some extent from the elastic molding die 1, but is not yet sufficiently peeled at the fine irregularities and the like above. In particular, if the fine irregularities are on the pressure chamber 22 side, the elastic mold 1 cannot be separated from the chocolate molded product at this location. Therefore,
The receiving member 26 is raised by an air cylinder, and the upper dish-shaped receiving portion is applied to the lower part of the chocolate molded product 30 (FIG. 4). In this case, the rising stroke of the receiving member 26 is set in advance to the distance to the lower end of the elastic molded product 1.

5)。When the receiving member 26 extends to the upper end, the distance h between the upper end of the receiving member 26 and the lower end of the pushing member is maintained.
Start descending at the same speed (Fig. 5). At this time, since the extrusion member 21 penetrates the core 20 and is located between the core and the elastic molding die 1, the uneven portion of the elastic molding die 1 is separated from the core 25 by the flow of the pressurized air, and is completely removed. The peeled state is obtained (FIG. 5).

Removed from conveyor and pushed out member 21
Is also returned to the upper position of the core 20, and the release pressure chamber 12 is also removed upward from the belt conveyor 3 to return (FIG. 6).

伸張することが難しくなるためである。Although not an essential part of the present invention, the angle θ between the horizontal line and the funnel-shaped slope located between the filling portion 8 of the elastic mold 1 and the fixed portion fixed to the fixed frame 19 is as follows. 5 °
At the same time as the range of ~ 35 °, this part is preferably an arm bending part having a radius of curvature larger than the radius, from the viewpoint of mold release. When the angle is less than 5 °, when the elastic mold is immersed in a latex solution or the like, the same portion becomes thick and a thick ring shape is formed in the mold, making it difficult to release the mold. In this case, it is difficult to extend the adjustment portion, which is a place where the product is taken out, in the lateral direction.
