[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a molding device made of resin and configured to be recyclable. Here, the above-mentioned utensils are understood in a broad sense, and include not only tableware, but also trays and dining tables.

[0002]

[Prior art]

 In recent years, most daily necessities, such as vessels, have been molded using resin, and in many cases, resin molded parts have been partially assembled. Since resin moldings can be easily and cheaply injected by injecting the resin into a mold, the range of use is not limited to containers, but is used in all fields such as furniture and car parts. However, when these resin molded products are no longer needed, they cannot be incinerated due to the generation of dioxin, and cannot be returned to the soil even if they are landfilled. ing.

[0003] Therefore, it is necessary to recycle the molded article to be disposed of, and if the unused molded article is finely crushed and injection-molded again, another molded article is completed. Conventionally, there is a technique for recycling a resin molded article which has become unnecessary. For example, “painted molded article and a method and apparatus for regenerating the same” according to International Publication No. In addition to enabling the recycling of goods and suppressing the deterioration of physical properties during recycling, it eliminates special processes, enables easy and inexpensive recycling, and realizes effective use of resources.

Meanwhile, a conventional molding machine generally uses an ABS resin, and the surface thereof is coated with a urethane resin. However, such a molding machine cannot be finely pulverized and used as a material for injection molding. This is because ABS resin and urethane cannot be mixed, and if melted, they will separate from each other. If this is used as an injection molding material, dust will adhere to the surface of the molded product. And does not have a clean molding surface. Therefore, in order to recycle, the urethane layer coated on the surface must be scraped off with sandpaper.

[0005]

[Problems to be solved by the invention]

 As described above, there is a problem as described above in recycling a conventional molding machine. The problem to be solved by the present invention is this problem, and a molding machine that can be recycled without removing the surface coating film is provided.

[0006]

[Means for solving the problem]

 The molding device according to the present invention is injection molded using ABS resin as a material, and an acrylic paint is applied to the surface. Acrylic paint has the property of being mixed with ABS resin, and therefore can be recycled without removing the acrylic paint film applied to the surface. In other words, the formed vessel is finely ground and melted as it is, and this is injection molded to produce another vessel.

[0007] The acrylic paint is completely mixed with the ABS resin and molded, and the surface is beautifully finished. Then, an acrylic paint is applied again to the surface of the formed container. In this regard, the molding device of the present invention forms a wood grain pattern or the like on its surface, and makes the acrylic coating film inconspicuous even if it is scratched. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

[0008]

【Example】

 FIG. 1 is an embodiment showing a resin-made device according to the present invention, and shows a cross section thereof. Although the present invention is intended for vessels and does not specify the specific type, the examples show the most basic trays. The vessel rises with an outer portion 2 inclined around a bottom portion 1, the bottom portion 1 and the outer portion 2 both have a double structure, and have a continuous space 3 inside. The container is injection-molded using resin as a material, and the surface is painted and provided with a coating film 4 as shown in FIG.

The coating film 4 uses an acrylic paint and is applied to the surface of the formed container. After being applied to the surface of the molding machine using this acrylic paint, it is dried at a temperature of 60 ° C to 100 ° C. By the way, the acrylic paint has a property of being completely mixed with the ABS resin constituting the container, and if mixed and dissolved together, it is uniformly mixed and does not separate. Acrylic paint is applied to the surface of the formed tableware by any means, resulting in a beautiful and glossy surface.

[0010] Even when an acrylic paint is used as a coating material, the quality is not inferior to that of a conventional urethane paint. However, since the acrylic coating film is vulnerable to scratches and the like, it is preferable to form a grain pattern or the like on the surface of the molding device in advance. In other words, by forming the wood grain pattern, even if the coating film is scratched, it becomes less noticeable.

When the molding machine of the present invention is worn out and becomes unnecessary, the molding machine is finely pulverized into fine particles, which are put into a hopper of an injection molding machine and moved in a cylinder by a screw while being screwed. It is heated and melted and injected from the nozzle into the mold.

[0012] A pulverizer is used to finely crush a relatively large molding device. This pulverizer has been conventionally known, and has been conventionally used when a runner or a sprue generated at the time of molding is finely reused. As described above, the molding device of the present invention is formed by injection molding into a predetermined shape using ABS resin, and the surface thereof is coated with an acrylic paint, and the following effects can be obtained. .

[0013]

[Effect of the invention]

 Since the molding device of the present invention is molded using ABS resin and the surface is coated with an acrylic paint, the unnecessary device is used as it is in a pulverizer to form fine particles, which are then put into a hopper and injection molded. I can do it. In this case, the acrylic paint can be completely mixed with the ABS resin, so that the surface of the molded container or the like has a glossy finish.

[0014] Therefore, unlike the conventional case, it is not necessary to scrape off the coating film on the surface with sandpaper or the like, and it is possible to crush and recycle the film as it is, which is very economical, and also saves resources and protects the environment. It has a great effect. In addition, since the acrylic coating film is vulnerable to scratches, by forming a pattern such as wood grain on the surface of the vessel, the scratches become inconspicuous.
