DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described with reference to the accompanying drawings.

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). ) Is fixed to the endless conveyor belt 3 wound around the pulley 2 in a replaceable manner. 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. 3 is fitted in an elastic mold in close contact from below. After the fitting, the pressure in the pressure chamber 5 is reduced to a negative pressure by the pressure control device 4 so that the elastic molding die 1
Inhales the outside air from the opening 9 at the top of the
A predetermined amount of fluid chocolate 6 as a liquid filler whose temperature has been adjusted by tempering in advance is discharged from a storage tank 7 into a filling section 8 of the elastic mold 1 by a nozzle via a metering device (not shown). Then, 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 mold 1 is vibrated by the vibrator 10 while moving the conveyor belt 3, The liquid chocolate in the mold is solidified by being immersed in the cooling tunnel 11 as the solidification step B for a predetermined time. Furthermore, the elastic mold 1
Moves to the mold release step C, and lowers the mold release pressure chamber 12 in the direction of the arrow by an up-down moving device (not shown) to move the elastic molding die 1.
Are fitted in a close contact state from above. In this state, the pressure in the mold release pressure chamber 12 is set 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, thereby solidifying the panda-shaped chocolate product 14 inside the mold. Is dropped onto the conveyor 15 and the product collection container 16
To collect the product. After the mold release, the elastic molding die 1 blows off the residual chocolate in the die by air, and is then sent to a preheater 17 as a preheating step D, and the inside of the die is made substantially the same as the chocolate discharge temperature in the filling step A. To maintain the quality of the decorative product in a certain glossy and good quality. It should be noted that FIG.
Numeral 8 is a seal member with the conveyor belt 3 attached to the lower part of the filling or releasing pressure chamber.

The improved apparatus and method of the present invention in the releasing step C will be described below with reference to FIGS.

The panda-shaped elastic molding die 1 is fitted as an endless line into holes formed at predetermined intervals in the belt conveyor 3 that moves intermittently, and is fixed by a fixing frame 19. The elastic molding die 1 which has been inverted the state of the filling step A and moved the opening 9 downward is in a state in which a cooling and solidified panda-shaped decorative product is accommodated in the filling part 8. . In this state, a release pressure chamber 12 that can be moved up and down by a vertical moving device (not shown) is provided above the opening opposite to the elastic molding die. In the release pressure chamber 12, a porous core 20 having substantially the same shape as the expanded shape of the elastic molding die is provided. The pressure chamber 12 includes a pressure control device 13
Thereby, the same chamber is sucked to a negative pressure state through the pressure pipe 22.

Reference numerals 18 and 19 denote sealing materials provided on the lower peripheral edge of the release pressure chamber and the upper peripheral edge of the fitting chamber 25, respectively.

The elastic molds 1 fixed to the conveyor belt 3 one by one at predetermined intervals and the release pressure chambers 12 disposed above the elastic molds 1 are, as shown in FIG. For example, it is more preferable to arrange a plurality of units in parallel to six or eight units in order to improve the work efficiency.

The following steps are used to take out a solidified chocolate molded product as a filler using the release apparatus having the above configuration.

First, the elastic molding die 1 is moved to the belt conveyor 3.
To stop immediately below the release pressure chamber 12, lower the release pressure chamber 12 by a vertical moving device (FIG. 2), and seal the sealing material 18 provided on the upper and lower peripheral edges of each chamber with the fixing frame 1 of the belt conveyor.
The mold 1 is fitted into the core 25 by being in close contact with the mold 9.

Next, air in the release pressure chamber 12 is sucked by the pressure control device 13. In this case, the release pressure chamber 12
Flows from the opening 9 of the elastic mold 1 to the pressure pipe 22, between which the porous core 20 flows.
Therefore, a pressure difference occurs between a positive pressure state and a negative pressure state before and after the air enters the perforation, and the elastic mold 1 expands and expands along the inner surface of the core 20 to join. Then, the decorative product 14 is separated from the filling portion 8 of the elastic mold 1 (FIG. 3).

The angle formed by the filling portion 8 of the elastic mold 1 and the funnel-shaped taper portion as a fixing portion fixed to the fixing frame is in the range of 5 ° to 35 °, and this portion is larger than the radius. It is preferable to use an arm bent portion in order to facilitate release of the decorative product 14. If this angle setting is less than 5 °, when the elastic molding die is immersed in a latex solution or the like, this portion becomes thick and a thick ring shape is formed in the mold, making it difficult to release. If it exceeds 35 °, it is difficult to expand in the lateral direction at the time of releasing, and it is also difficult to release. Further, in the above embodiment, the decoration product 14 was taken out of the elastic molding die 1 by sucking air from the opposite opening of the elastic molding die by the pressure control device 13 into the mold release pressure chamber to make the interior a negative pressure state. On the contrary, it is considered that the decorative product is peeled off from the inner wall of the mold by expanding the elastic mold 1 to the inner surface of the porous core by applying a positive pressure from the opening side. Can be

In this manner, the fluid chocolate filled in the filling step is solidified by passing through the cooling tunnel 11 as the solidifying step, and the panda-decorated chocolate as the product solidified by the release pressure chamber 12 is taken out. Also,
Before the filling process is started again, the elastic mold 1
Is heated, and the temperature of the mold is made substantially the same as the temperature of the fluid chocolate at the time of filling, thereby reducing defective products. Further, a decorative product having no pinholes on the surface is obtained.

In the above embodiment, the liquid chocolate was used as the filling material. However, in the present invention, it can also be used for molded articles of kamaboko, ice, plaster, eraser, soap, and other various plastic products. . Further, the solidification step includes not only cooling but also heating and solidifying like a kamaboko.

[0021]

As described above, the method and apparatus for molding a decorative product according to the present invention expands an elastic mold onto the inner surface of a porous core having substantially the same shape as the shape along the outer shape of the decorative product. Since the decorative product in the mold is taken out, the elastic mold can prevent the deformed expansion and improve the durability of the mold regardless of the thick part and the thin part.
