絵柄はかなりの耐摩耗性があると言える。Generally, methods for applying pictures to the surface of plastic molded products include screen printing with pigment-based ink, tacho printing, pigment transfer, labeling, etc., but these methods have poor abrasion resistance and solvent resistance. There are some difficulties in solving these problems, and there are some aspects that cannot be put to practical use under severe usage conditions. 'i' A method for obtaining patterns and letters with excellent abrasion resistance and solvent resistance, 1° is a method using a multicolor injection molding machine, and 1° is a method using a multicolor injection molding machine. The method using a machine involves preparing a mold for molding the pattern and a mold for molding the remaining σ〕81S in the subsequent process, molding the pattern in the first process, and then The other parts are molded in a unique position.With this method, even if the surface of the plastic molded product is slightly worn out, the designs and letters are fully legible and have sufficient quality. It has wear resistance.However, this method requires high mold costs;
There are drawbacks such as the inability to express a single character with a complicated shape or the fact that there are considerable restrictions on the shape of the molded product. On the other hand, the method using sublimation transfer involves placing the molded product in a predetermined jig in a separate process after molding the molded product, and adhering a transfer paper printed with ink containing a sublimable dye prepared in advance to the surface of the molded product. A heated rubber is pressed onto the back side of the transfer paper, and the dye in the ink is sublimated and permeated into the plastic molded product. According to this method, the dye penetrates several tens of micrometers into the plastic molded product, so it can be said that the pattern on the plastic molded product has considerable wear resistance.

There were drawbacks such as difficulties, the fact that not only the ink on the transfer paper but also the surface of the molded article must be heated during transfer to produce sufficient dye vM, and the transfer cycle becoming long.

It is attached to the male mold (6) and moves downward during resin injection and cooling, and is combined with the male mold (6). Male type (5
) is attached to the rotary table (7), and at least two types are required. There are two molds, one for molding and the other for transfer, which are located directly below the injection molding machine. In addition, if necessary, a discharge station and a σ) station for inspection may be provided depending on the molding and transfer cycles.

After that, the heating rubber plate (9) is lowered by the cylinder 00), and is pressed from the back side of the transfer film (old), and is pressed onto the molded product (]) to heat the ink (12) and remove the sublimable dye in the ink. is transferred into the plastic molded product (]). Thereafter, the heated rubber plate (9) and heated iron plate (8) are raised by the cylinder (10), and the painted glass molded product is discharged from the male mold (6), which is then transferred to the injection molding machine ( 3) Rotate and move directly below and enter the injection molding process.

る心配はない。According to the method of the present invention, it is possible to omit the complicated step of setting the molded product on a transfer jig, which was a drawback of the conventional lift-up-lift-up-turn-up method. In addition, in order to obtain an accurate positional relationship between the transfer paper and the molded product, there is no need for a safe and accurate transfer jig. In other words, since the injection molding male mold (6) directly serves as the transfer jig, the positional accuracy is very good and the cost of the transfer jig can be saved. Furthermore, since there is no positional deviation between the molded product fl) and the transfer jig, that is, the male die (6), there is no risk of deformation even if large pressure is accidentally applied to the molded product.

ロールすることが望ましい。Furthermore, the transfer cycle can be shortened. In other words, the molded product immediately after molding is not sufficiently cooled, and although it depends on the resin material and the cooling time and method, it is generally
He has a fever of about ℃~8MC. The method of the present invention considers actively utilizing this heat, and controls the height of the molded product before being subjected to transfer. That is, it is desirable to control the temperature at a temperature that does not deform the molded product even when the molds (4) and (6) are opened, and at the same time that it helps transfer the dye during transfer.

成形品自体が内部まで加熱されている為、従来の方法と
異なり、染料の移行が成形品内部まで深く浸透し易い。On the other hand, when thermosetting resins are used, compression molding, transfer molding, and other methods can also be used; they can be subjected to the transfer process at a much higher temperature than thermoplastic resins. It is more advantageous for dye sublimation. That is, in the cube of the present invention, the heat after molding can be used to assist the sublimation, penetration, and transfer of the dye, so that the transfer of the dye becomes faster and the time required for transfer can be shortened. In history,
Because the molded product itself is heated to the inside, unlike conventional methods, the dye can easily penetrate deep into the molded product.

の浸透深さ＆’；１２０〜３０μ程度のものであった。In other words, in the conventional method, the dye is simply heated and pressed from the back side of the transfer film, the dye is indirectly heated through the film or paper base material to sublimate it, and then the molded product is indirectly heated to create the molded product. The dye migration was aided by loosening the crystal structure or activating molecular motion, but the penetration depth was approximately 120 to 30μ.
