成形品が得られないからである。However, although this method is often used when painting on a flat surface such as a container cap or a plate, painting on the side of a container-shaped thing alone is not possible.
Not performed because it is affected by the resin flow. In other words, when the sheet is fixed on the inner side surface of the mold and the resin flows,
This is because, under the influence of this flow, the sheet piece is rolled up and a desired molded product cannot be obtained.
そこで、各種の収納容器類の側面へ射出成形と同時に

品を得ることができる。Therefore, when painting on the side surfaces of various storage containers at the same time as injection molding, a method of performing injection molding by mounting sheet pieces so as to be continuous from the bottom of the container has been adopted. As shown in FIG. 5, the sheet piece 6 used in this conventional injection molding method on the side surface of a container has a hole 10 in a portion serving as a resin flow port. By doing so, the fourth
As shown in the cross-sectional view of the injection mold shown in the figure, when the sheet 9 is adsorbed on the inner side surface of the fixed mold 2 by the action of static electricity, the resin 9 is injected from the nozzle 5 toward the cavity 3. The resin 9 passes through the hole 10 of the leaf piece 6 to reach the core portion of the movable mold 1, and flows while pressing the leaf piece 6 against the fixed mold 2. As a result, a desired molded article with a picture is obtained. Obtainable.

発生することが多かった。[Problem to be Solved by the Invention] In the conventional injection molding method with a picture for the container side surface,
It is necessary to set the sheet piece 6 continuously from the bottom to the side of the fixed mold 2, but since the sheet piece 6 of the film to be used is usually about 0.08 to 0.25 mm and very thin, It is difficult to set on the fixed mold 2, and
The printed sheet piece 6 has a portion that is not related to the pattern at the bottom and has a large area as a whole, so the portion that comes into contact with the flow becomes large, and it cannot withstand the flow of the resin 9 and wrinkles occur. I often did.

めるように溶融樹脂を射出した。When injecting the melted resin 9, the momentum in the cavity 3 is reduced where the resin 9 hits the sheet 6. That is, the injection speed at the position where the resin 9 is applied to the sheet piece 6 is set to 25 to 60% of the initial injection speed. Specifically, as an injection molding machine, a screw diameter of 40
φ, maximum injection pressure 1800kgf / cm 2 , maximum screw stroke 160mm, maximum injection speed 300mm / s, operating screw stroke range 65 ~ 10mm, resin temperature 200
The filling was performed by changing the injection speed as follows, with the filling temperature set at 70 ° C. and the filling pressure at 70% of the maximum injection pressure. That is, the screw position is 65 ~
45% of the maximum injection speed at 55mm, 25% at 55-50mm, 50 ~
45% for 14.5mm and 15% for 14.5-10mm. The last pressure holding condition was 30% of the maximum injection pressure for 1 second. As described above, when the screw position is 55 to 50 mm, the injection speed is once reduced to about 56% of the initial injection speed, so that the momentum in the cavity 3 is reduced where the molten resin 9 is applied to the single piece 6. The molten resin was injected.

するようにした。On the other hand, the resin 9 is temporarily cooled by the cooling water circulating in the cooling water passage 8 before the adsorbed sheet piece 6.
The cooling water temperature was 5 to 15 ° C., and the water pressure was 6 kg / cm 2 . As described above, the flow of the resin is once decelerated and the resin is cooled.
その後、樹脂９は枚葉片６の端部を過ぎると再び速く
流れるとともに、金型のもつ熱により加熱される。Thereafter, the resin 9 flows quickly again after passing through the end of the sheet piece 6, and is heated by the heat of the mold.

ができる。In the injection molding method with picture according to claim 2, which uses the injection molding die according to claim 1, the material 6 and the thickness of the sheet 6 are appropriately selected since the sheet 6 is strongly attracted by the suction unit 7. Thereby, a trace of the suction unit 7 can be generated on the sheet piece of the formed container in relation to the suction force. Then, in the above-described embodiment of the injection molding method, the molded article could be made to have an uneven shape as shown in FIG. 3 by this action. In this case, if the shape of the suction part 7 is appropriately changed, it is possible to obtain a molded product having desired irregularities. For example, various concave and convex shapes can be provided as suction holes instead of the suction grooves, or by combining them.
