It is arranged to be closed at a predetermined position necessary for performing foam molding. On the other hand, the second guide rail 12. are disposed over a range from a position where the lid 3 of the mold mold that moves upward begins to close, to a range where the mold is turned over downward and moves in the horizontal axis 5 direction. As is clear from FIG. 1, the second guide rail is arranged so that the cover body 3 is held down by the guide axle 4 running thereon. This prevents the lid 3 from being opened when the mold turns downward, and also allows the lid 3 to be opened before the mold moves downward and passes through the vacuum demolding device II. The redness has been adjusted. After the lid body 3 is opened, the second guide rail 12 for the presser foot is opened. is unnecessary, and the guide axle 4 is connected to the guide rail 12. After being removed, the lid body 3 moves while remaining open. Second guide rail 12. The position along which the lid and body 3 are opened is determined by various specific external conditions, but is at least the position where the foam raw material injected into the molding chamber 12 has been sufficiently foam-molded.

In FIG. 1, the area indicated by A indicates a heating zone for foaming the foam raw material, and the area B indicates a mold temperature adjustment zone by water cooling.

The operation of manufacturing a cosmetic puff made of polyurethane foam using the foam mold manufacturing apparatus having the above-mentioned structure will be explained as follows.

First, when the upwardly facing mold moves below the foam raw material injection nozzle 70 with the lid body 3 open, the rotating gear 6 is stopped for a period of time necessary for injecting the foam raw material. In this way, the rotary gear 6 has one mold mold directly below the nozzle 7.
- After stopping the dispensing for a predetermined time, insert the next mold into nozzle 7.
It is controlled so that it is moved directly below. When the mold stops just below the foam raw material injection nozzle 7, the nozzle 7 descends to just above the lower mold 1. Next, pump 81*
8t is raw material tank 91.9. The polyurethane foam raw material components are injected into the nozzle 7 at high pressure. In this way, the polyurethane foam raw materials are mixed in the nozzle 7.
Then, the nozzle 7 injects a predetermined amount (12~], Oy) of this polyurethane foam raw material into the molding chamber 2.

When the raw material injection is finished, the nozzle 7 is returned to its original position. The molds into which the foam material has been injected are successively moved in the direction of the arrows in FIG. 1, and sent to the heating zone A with the lid 3 kept open.

In heating zone A, foam molding and curing steps are performed as follows. That is, the mold enters the heating zone with the lid open, is heated, and the foam raw material in the molding chamber 2 is foamed. This foaming action progresses as the mold moves, and the foam raw material gradually expands and rises from the opening of the molding chamber 2. And guide rail 12□.

No2. is arranged so that the lid 3 is closed immediately before the foaming action is completed; therefore, the lid 3 is closed immediately before the foaming action is completed.

At this time, since the raised foam raw material has not yet been cured, it is easily compressed by the lid 3 held down by the second guide rail 12°, and the mold is completely closed. The mold thus closed is turned over in the direction t'F and moved along the second nozzle rail 122 while remaining closed. During this time, foaming and molding are performed in the molding chamber 2, and then the lid 3 is gradually opened along the second guide rail 12°. In this embodiment, the second guide rail is adjusted so that the lid 3 is opened in the heating zone A, and the remaining lid 3 passes through the heating zone with the lid 3 open. The foamed molded product cannot be polished.

After completing the foam molding and curing process in the heating zone A, the mold is sent directly above the vacuum demolding device 11 with the lid 3 open and facing downward, and stopped there. The vacuum-type demolding device 11 extends its arm and adsorbs the suction plate at its tip to the foam molded product in the molding chamber 2, and then releases the foam molded product by extending its arm. .

Then, the demolding device 1 rotates its arm 180 degrees in the direction of the arrow, and removes the foamed molded product adsorbed at the tip by 1 [V sheath box 13
Contains the fall inside. 14 is a foamed molded body housed in the storage box 13.

The mold from which the foamed molded body 14 has been removed is sent to the mold temperature adjustment zone B. While passing through this adjustment zone B, the mold is adjusted to an appropriate temperature and is turned upward by -F or C.

At that time, Gaitl transport 4 was Idrail 12. By traveling above, the mold-shaped lid 3 facing upward becomes open and is sent directly below the foam raw material injection nozzle 7 as it is.

Thereafter, the above-described steps are repeated to continuously produce a foamed molded article.

As explained above, according to the foam mold body manufacturing apparatus of the above embodiment, foam molding can be carried out continuously, and lines can be arranged vertically in three dimensions, so that the apparatus can be configured compactly. be able to. Therefore,
A very significant effect can be obtained in making effective use of factory space. In this case, since the mold includes a portion in which it moves downward, the present invention is suitable for an apparatus for producing a foam mold body for small items in which the molds overlap with each other with a small amount.

Of course, the heating zone A and temperature adjustment zone B in the above embodiments are not necessarily necessary when using a foam raw material that does not require heating for foaming.

In addition, in the above embodiment, the lid 3
The foaming gas is allowed to escape outside the mold by closing the mold, but if a mold with a gas vent hole formed in the lid 3 is used, the mold can be completely closed (after the heating zone A is removed from the mold). A guide rail 12..12. may be arranged so as to pass therethrough.

Furthermore, the installation of the vacuum-type clothing-type device 1] is optional;
It is also possible to remove the mold manually without installing this.

As described in detail above, according to the present invention, the production line can be arranged three-dimensionally to have a compact configuration, which is suitable for manufacturing small products that can effectively utilize factory space. A foam mold body manufacturing apparatus can be provided.
