[Problem that the idea aims to solve]

Therefore, the molded product 60 is removed from the production line from the conventional elastic mold 20. It is necessary to remove the mold by vacuuming the inside of the negative pressure chamber 35, for example. When inflating the elastic mold 20, the outlet port 13 is thick. Because it is difficult to expand, molded products cannot be cut out smoothly, and differences in film thickness may occur. This causes the problem that the expansion is not uniform, causing distortion and impairing durability. there were. Specifically, as shown in FIGS. 8 to 10, the mold holding part 12 is The elastic mold 20 fixed on a part of the conveyor etc. is moved to the negative pressure chamber 35, and first, as shown in FIG. , the inside of the negative pressure chamber 35 is made negative pressure by the vacuum shown by the arrow, and the vacuum is further increased. By continuing, the elastic mold 20 is expanded from FIG. 9 to FIG. 10. However, fig. 9 and 10, the outlet 13 of the elastic mold 20 is sufficiently large for thick walls. The problem arises that it cannot be expanded.

0004 This idea was developed after researching the above problems to improve the durability of elastic molds. It is an object of the present invention to provide an elastic mold that makes it easy to take out a molded product.

[0005]

[Means to solve the problem]

This invention solves the above problems, and its gist is to fill the interior with fluid. A product molding section for obtaining a molded product by filling and solidifying materials, and a product molding section An elastic molding mold consisting of a mold holding part that is integrally molded and continuous with the outlet for the molded product. In this step, the outlet formed by the product forming part and the mold holding part has a uniform thickness and is shaped into a curved arm. The elastic mold is characterized by the following:

[0006] The above-mentioned fluid filler is used for chocolate confectionery as a molded product, liquid for ice confectionery, etc. To obtain body parts, foods such as jelly sweets, daily necessities such as soap, wax, and gypsum, etc. This includes substances that are initially liquid but can be solidified by cooling or heating. Ru. The elastic mold is made of rubber such as latex rubber or resin, Filler refers to something that is solidified into an elastic film from a fluid substance such as a liquid. There is a product molding section where the product is filled and solidified, and a take-out port at the open end of this product molding section. and a mold holder that is continuously fixed to the automatic molded product manufacturing equipment. Furthermore, here The mold holding part is not only flat in relation to the product molding part, but also funnel-shaped, cylindrical, and other shapes. A combination of these shapes is possible.

[0007]

[Effect]

In this idea, the corners of the molding master mold formed by the product molding part and the mold holding part are formed into arm bends. By doing this, when the molding master is immersed in a solution of elastic material, the elastic material is The film thickness is almost uniform near the outlet without being concentrated at the corners, and the arm is curved for a smoother look. This allows the elastic material to expand smoothly and the molded product to be removed. Wear. Specifically, as shown in FIGS. 3 to 5, the mold holding section 2 is installed as part of the manufacturing line. The elastic mold 10 fixed on a conveyor or the like is transferred to the negative pressure chamber 35, and as shown in FIG. Make negative pressure inside the negative pressure chamber 35 using a vacuum according to the arrow, and continue vacuuming. The elastic mold 10 is expanded as shown in FIGS. 4 and 5 by the steps shown in FIG. At this time, elastic mold 1 Since the outlet of 0 has a uniform wall thickness and is formed into a curved arm, the expansion is caused by the fully elastic mold 10. The molded product can be easily released from the mold.
