Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that in order to decorate a non-smooth pattern, character or the like on the surface of the resin molding of a product used before, there is only a method for copying the pattern or the character by working the surface of the mold or a method for coating and printing, which requires high cost and which is hence not proper for a small lot. <P>SOLUTION: A method for manufacturing a molding using a printing sheet comprises the steps of: inserting a base film worked in or printed on a predetermined surface shape into molds 1, 2; clamping the molds; then pouring a resin of a molten state in the mold; and solidifying the resin to form a resin molding 3. The method further comprises the steps of: simultaneously integrally bringing the base film into contact, taking out the film after opening the mold, and releasing the film. The method also comprises a step of transferring the surface shape and an ink simultaneously to front and rear surfaces of the molding or only one side surface. <P>COPYRIGHT: (C)2004,JPO

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a game machine and
It relates to other decorative panels.

[0002]

2. Description of the Related Art In the products which have been used before, the surface of a resin molded product may be decorated with a non-smooth pattern, characters, etc. by a method of processing the mold surface and copying it, or by painting and printing. There was a way. (For example, Japanese Patent Fair 08-
Also, the film was inserted, heat-welded and integrated with the resin product.

[0003]

The processing of the surface of the mold is
It is expensive and unsuitable for small lots, and there are environmental hygiene problems and durability problems in painting and printing.

In order to solve the problem, an object of the present invention is to decorate the resin surface without processing the mold surface or coating and printing, or processing the resin surface or coating and printing.

[0005]

[Means for Solving the Problems] In order to achieve the above object,
The present invention is processed into a predetermined surface shape, insert the insert film into the mold, after mold clamping, inject the molten resin into the mold, to form a resin molded product by solidifying the resin, At the same time, the inserted film is closely adhered, and after the mold is opened, the molded product is taken out and the film is peeled off, so that the surface shape of the film and the ink can be transferred to the front surface or the back surface of the molded product at the same time or on only one surface. .

Further, the material of the base film is vinyl chloride,
All printable resins such as polypropylene resin, polyester resin, polycarbonate resin, etc. have a thickness of 0.1
Around mm is ideal but not limited, and if it can be inserted into the mold, this is not limited either. Furthermore, the present invention is not limited to injection molding, blow molding, vacuum molding, pressure molding, injection molding, or any of these, and is configured to transfer unevenness from a printed sheet.

Further, the surface shape formed on the molding sheet is transferred by molding by processing such as silk printing, offset printing, gravure printing, seal printing, UV irradiation, embossing and potting. Further, by selecting the ink, the internal pattern itself having the shape formed on the film was transferred, or only the unevenness was transferred.

Further, the resin used for molding is composed of a thermoplastic resin, a two-liquid type injection type resin, and a resin which can be transferred from a printed sheet.

[0009]

EXAMPLE An example of an embodiment of the present invention will be described in detail with reference to FIG. The resin mold product (3) and the base film (4) are molded by tightening the fixed mold (1) and the movable mold (2).

At this time, the base material film (4) processed into a predetermined surface shape is inserted into the mold, and after the mold is clamped, the molten resin is injected into the mold to solidify the resin.
A resin molded product (3) is molded. The base material film (4) inserted at the same time is brought into close contact with each other, and after the mold is opened, the molded product (3) is taken out and the base material film (4) is peeled off at the same time on the front surface or the back surface of the molded product, or The surface shape of the substrate film (4) and the ink are transferred onto only one side.

Further, printing layers (7, 8) are formed on the surface of the substrate film (4). In some cases, the surface of the printed layer is cured by UV irradiation or the like. The base film is sucked through the vacuum suction holes (6) of the movable mold (2). Then, the injection molding resin (3) is injected into the mold through the gate portion (5). After that, the mold is opened, the resin molded product (3) is taken out, and the printed layer (7, 8) is formed together with the base film (4).
When peeled off, the convex shape of the printing layer was transferred to the resin molded product.

[0012]

Since the present invention is configured as described above, it has the following effects. The present invention inserts a base material film processed into a predetermined surface shape into a mold, and after the mold is clamped, a resin is injected into the mold and a resin molded product is molded by solidifying the resin, which is simultaneously inserted. The base film is integrally adhered, the molded product is taken out after mold opening, and the surface of the molded product is peeled off by peeling the base film at the same time, or only on one side, and the surface shape of the film and the ink are transferred, With the above configuration, by processing the base film to be inserted instead of processing the mold, the processing itself is simple and inexpensive, and it is easy to produce products in small lots. became.

Further, by selecting an ink, a pattern itself of a part of the shape formed on the film was transferred.
