に関し、特に角型容器を成形するための金型に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for forming a label-integrated container by inserting a label into a mold and then injecting a resin, and more particularly to a mold for molding a rectangular container.

Description of the Related Art A technique for integrally providing a product label (printed on synthetic paper) on a side surface of a cylindrical resin container, for example, a resin cup, that is, a label insert molding technique is well known in the art. The technology is shown in Fig. 3 (a).
As shown in Fig. 3, a label 3 which is lightly rolled in advance with the same diameter as the cavity 2 is inserted into the inner surface of the cavity 2 and the mold is clamped (Fig.
(B)) After the resin is injected and the mold is opened, there is a label on the surface.
The process is performed by removing the resin container.

The order, inserting the label 3 into the cavity 2 of the square
At this time, unless the label 3 is formed so as to be in close contact with the inner surface of the cavity 2 , the label 3 cannot be satisfactorily inserted into the label.

ラベル３の端部に当り、ラベル３を押し潰してしまう。That is, when the cylindrical label 3 is inserted into the cylindrical cavity 2, the synthetic paper of the label 3 is inserted.
The elastic force of the
It works uniformly and projects along the inner surface of the cavity 2. However, the label 3 inserted in the cavity 2 of the rectangular container is
The elastic force does not work so as to be similar to the cavity 2, that is , the label 3 remains round in the square hole.
It Therefore, when the mold is clamped, that is, the core 1 is the cavity
When it is inserted into the label 2, the end of the rectangular core 1 hits the end of the rounded label 3, and the label 3 is crushed.

きであった。In order to prevent this, the label 3 is made thick and is formed in advance by making a crease in the shape of a rectangular container.
Further, it is necessary to slow down the mold clamping speed of the core 1 so that the inserted label 3 is not crushed by the core 1 during mold clamping. Therefore, the above method requires a large number of steps and requires a long process time, and thus is not suitable for so-called thin high-cycle molding for mass production with thin resin.
