[0002]

2. Description of the Related Art Conventionally, chocolate molding has been performed using an elastic mold.
There is known a method of forming a doll, a jelly or the like into a shape such as a doll or an animal. The conventional elastic molding die used for this molding includes an elastic molding die made of an elastic film molded into a desired shape such as a doll and an animal, and an elastic molding die connected to an opening of the elastic molding die to support the elastic molding die. And a supporting portion made of an elastic film. In order to mold a molding material using this elastic mold, the end of the support portion is held by, for example, an annular frame, and the elastic mold is suspended along with the support. A method is used in which a molding material in a flowing state is poured and filled from a portion, and then the molding material poured into the mold body is cooled and heated to be solidified, and then the solidified molded product is taken out from the elastic molding die. .

Conventionally, this solidified molded product is taken out from an opening by expanding an elastic molding die by utilizing a difference in air pressure.
That is, for example, a cup provided with a vent is placed over the entire elastic mold, and the air inside the cup is sucked from the vent to decompress the inside of the cup and expand the elastic mold, or a cup provided with a vent. Put the air on the support part side of the elastic mold, press the air into the cup from the ventilation port and pressurize the inside of the cup to expand the elastic mold, or expand the elastic mold by using both, This is performed by a method in which a molded product is released from an elastic molding die and is taken out from an opening that has expanded and expanded.

[0004] The molding method using the elastic mold is characterized in that molded articles of various shapes can be molded easily and inexpensively. It is easy to mold not only a molded product with a tapered shape toward the end, but also a molded product with an inverted taper from the opening of the elastic mold toward the tip end. Although it is possible, for example, when molding a complex shape such as the shape of a rose flower in FIG. 7 and having a deep reverse taper, there is a limit to the expansion of the opening, and in some cases, There is a risk of damaging the molded product.

[0005]

SUMMARY OF THE INVENTION According to the present invention, when molding using a hollow elastic molding die having an opening formed of an elastic film, regardless of the shape of the molded product, the removal operation of the molded product is performed. An object of the present invention is to provide an elastic mold that is easy and can be taken out without damaging a molded product.

[0006]

SUMMARY OF THE INVENTION The present inventors have found that when molding using a hollow elastic molding die having an opening formed of an elastic film, a molded article having any complicated shape can be easily taken out. As a result of various studies on possible elastic molds, the present inventors came up with the idea of expanding the elastic molds at the cuts when taking out cuts in the elastic molds and taking out the molded product.

That is, the inventor of the present invention is an elastic mold having a hollow elastic mold formed of an elastic film and having an opening, wherein one or more cuts are provided in the elastic mold. In addition, the present invention relates to an elastic molding die provided with a piece covering a cut or a bellows extending across the cut outside the elastic molding die.

The present invention will be described in detail with reference to the drawings showing one example. The elastic mold of the present invention has a sectional view as shown in FIG. FIG. 1 is a cross-sectional view of an elastic mold for molding the rose-shaped molded article of FIG. 1
Numeral 2 denotes an elastic molding die, and 2 denotes a supporting portion which extends continuously outward from the opening 3 of the elastic molding die. Reference numeral 4 denotes a support frame for supporting the elastic mold. The elastic mold 1 and the support 2 are formed of an elastic film made of an elastomer. Elastomer
For example, natural rubber, chloroprene rubber, or the like is used. The support portion 2 extending outward from the opening portion 3 is shown in FIG.
In the figure, it expands conically from the opening 3, but has an elliptical cone shape.
It may extend upward and outward in an arbitrary pyramid shape such as a pyramid shape, or may extend horizontally outward. Support frame 4
Is circular and grips the end of the support 2.

The elastic molding die 1 is suspended from the supporting frame 4 via the support portion 2, a molding material, for example, a molten chocolate is poured from the opening 3 of the elastic molding die 1, and then cooled and solidified. In the elastic molding die of the present invention, a solidified molded product can be taken out by expanding a cut (not shown) provided in the elastic molding die. The cuts can be provided in an arbitrary number, an arbitrary place, and an arbitrary shape according to the shape of the molded product. That is, for example, a cut may be provided independently at one or more places of the elastic mold, a cut may be provided from the opening to the tip of the elastic mold, or the shape of the elastic mold may be complicated. A cut may be provided from a suitable point, that is, a point where the molded product is most likely to be damaged when taken out, from the tip of the elastic mold, or the cuts may cross each other like a cross.

[0010] A piece (a palm) for covering the cut may be provided outside the elastic mold along the cut. The risk of the molding material flowing out of the cut during molding is reduced.
Only one side of the piece covering the cut is connected to the elastic mold along the cut so as not to hinder the spread of the cut.

However, when molding is performed using an elastic molding die having a cut, a swelling due to the cut is likely to occur in the molded body, and the appearance may be impaired. For this reason, it is preferable that the cut is provided at a less noticeable portion of the molded product as much as possible. For example, when a molded article having a shape like a rose flower in FIG. 7 is formed, if a cut is made in the flower villa, a beautiful flower villa cannot be formed. Is provided.

FIG. 2 is a perspective view of one example of a cut elastic elastic mold according to the present invention as viewed from obliquely below. Reference numeral 1 denotes an elastic molding die made of an elastic film, and reference numeral 2 denotes a support portion made of an elastic film and extending conically outward from an opening 3 of the elastic molding die. 5 is a break. Further, a is an end of the cut 5 in the support portion 2, and b is an end of the cut 5 in the shaping portion of the flower villa. In the example of FIG. 2, the cuts are provided at three places at approximately the same intervals (one cut is not shown). However, when the shape of the elastic mold is complicated, that is, when the molded product is taken out, the molded product is most often taken out. It is preferably provided at a location that is easily damaged. Also, so as to cover the cut 5 of the elastic mold 1,
An elongated piece may be provided on the outside. Only one of the two elongated sides of this piece is joined to the elastic mold.

FIG. 3 is a perspective view of an example of the elastic mold of the present invention in which the cut is covered with a piece as viewed from obliquely below. A piece 6 is provided to cover the cut 5 provided in the elastic mold 1 and the support portion 2. FIG. 4 is a plan view of the elastic molding die.
The piece 6 has only one side 7 joined to the supporting portion 2 to be integrated. Therefore, it does not hinder the expansion of the elastic mold 1 to a desired size. The risk of the molding material flowing out of the cut during molding is reduced.

A molded article is taken out using the elastic mold of the present invention as follows. That is, after the molding material poured into the elastic mold is solidified, the elastic mold 1 is removed from the support frame, and the support portion 2 is expanded in three directions at the cut.
Since the elastic mold 1 can also be expanded from the cut, the molded product can be easily taken out. Thus, the molded product can be removed without damage. At this time, the work is facilitated if the support frame is divided so that the support frame itself is mechanically expanded and the support portion 2 and the elastic mold 1 are expanded from the cut.

Incidentally, the elastic mold is used for molding repeatedly many times. When the elastic mold shown in FIG. 2 is used repeatedly, the elastic mold is expanded at each cut, so that the cut tears from a predetermined position, that is, the end b of the cut in FIG. Eventually, it may reach the flower villa and become unusable. In order to eliminate this hindrance, it is preferable to provide a bellows straddling the cut outside the elastic mold.

FIG. 5 is a perspective view showing one example of the elastic molding die viewed obliquely from below. A bellows 8 is provided across the cut 5 provided in the elastic mold 1 and the support portion 2. FIG. 6 is a plan view of the elastic molding die. Bellows 8
Are provided with a margin so that the support portion 2 and the elastic mold 1 can be expanded to a desired size. Since the elastic mold has the bellows 8 and suppresses the expansion of the elastic mold, even if the elastic mold is used several times, the tip of the cut does not tear.

[0017]

According to the present invention, there is provided a hollow elastic mold having an opening formed in an elastic film and having one or more cuts in the elastic mold. Is extremely easy, and the molded product is not damaged during removal. In addition, a piece that covers the cut is provided outside the elastic mold so that the molding material can be prevented from flowing out of the cut during molding. Furthermore, by providing the bellows over the cut, the tip of the cut does not tear even if the elastic mold is used repeatedly.
