サートする場合には、平坦面にブイルムをインサートす
るときと異なって、インサートフィルムをキャビティの
立体面に沿うように予備成形している。When inserting a film into the three-dimensional surface of a cavity to decorate a three-dimensional surface of a synthetic resin molded product, such as a part with an uneven surface, using a colored film, or to cover the three-dimensional surface with a film, it is necessary to insert a builm on the flat surface. Unlike when inserting, the insert film is preformed so as to follow the three-dimensional surface of the cavity.

給装置も特別なものが用意されなければならなかった。Press forming, vacuum forming, etc. are used for this preforming, and in order to prevent the film from deforming, thick or hard films are used, and thin films that are exposed are not used. It was difficult. Furthermore, when inserting a preformed product, alignment is required, and a special feeding device must be prepared.

なう。According to the present invention, a cavity having a three-dimensional surface on the side of the movable mold is formed by a fixed mold and a movable mold into which a core mold equipped with a film suction means is inserted so as to be freely retractable.
The three-dimensional surface may extend only around the core mold or the entire movable mold, and any three-dimensional surface can be used as long as the dimensions of the film inserted therein are changed according to the area of the three-dimensional surface. can also be made compatible. The film is inserted by suctioning and holding the film on the core mold surface with the core mold surface protruding from the three-dimensional surface.

沿いインサートする。The film may be soft and thin, and any film can be used as the insert film as long as it has the flexibility to deform along a three-dimensional plane. The film held by suction on the core mold surface is inserted along the three-dimensional surface by relative movement between the movable mold and the core mold, for example, by movement of the movable mold in the mold closing direction or by moving the core mold backward.
更にこの発明を図示の実施例により詳細に説明する。Further, the present invention will be explained in detail with reference to illustrated embodiments.

ト９にはエジエクタピン１２が当接してある。The inner end of the core mold 3 is formed in a recess, and a pedestal 3a is inserted into the recess in combination with a rod 3b inserted into the center of the core mold. Around the pedestal 3a and rod 3b, there is a gap 3c for vacuum adsorption, which is suitable for the exhaust passage 6 provided in the movable mold 2 and the core mold 3, and adsorbs the film 7 on the mold surface of the core mold during depressurization. It is now possible to do so.
Further, an ejector plate 9 that is constantly pressed outward by a spring member 8 provided between the core mold 3 and the movable mold 2 is connected to the outer end of the core mold 3 by a member 11 that supports the rod 3b via a spring member 10. An ejector pin 12 is in contact with the ejector plate 9.
しかして、上記キヤビティ５にフィルム７をインサート

てがわれ、更に吸着保持される。This protrusion is generated by pressing the core mold 3 through the ejector plate 9 with the ejector pin 12. During or after the ejection operation of the core mold 3, the pressure in the gap 3c is reduced, and the film 7 is supplied onto the surface of the core mold using an automatic inserting machine. The film 7 is a hollyhock film that is colored or patterned and cut approximately equal to the surface area of the portion of the three-dimensional surface 4 to be decorated or covered, and is applied to the core mold surface in a predetermined state. It is further adsorbed and held.

At the same time, the movable mold 2 is closed. In this case, the mold may be closed first, and then the core mold 3 may be retreated. The core mold 3 is retracted by removing the pressure from the ejector pin 12, and the film 7 is inserted along the three-dimensional surface 4. Then, when the cavity 5 is filled with molten resin, the film 7 is formed on the three-dimensional surface 4.
The top surface formed into an uneven surface is the film 7.
A molded article 13 coated with this is formed. The molded product 13 can be easily released by ejecting the core mold 3 again, and in some cases, it can also be released from the surface of the core mold by pumping air into the reduced pressure gap 3c.

The back diameter of the insertion hole 15 is slightly larger than the cavity diameter, and an edge member 14 is embedded around the back opening. The outer diameter of the fixing part 3d of the core mold 3 is formed to be equal to the cavity side diameter of the insertion hole 15, and when it is located in the insertion hole 15 and forms a part of the cavity with the core end surface, the edge part 14
There is a gap 15a between which the cutting edge of the cutter described later fits.

There is a gap 3c around each of the rod 3b and the pedestal 3a, and the pressure in the gap 3c is reduced so that the cut film 7 can be adsorbed onto the core mold surface.
A movable member 16 is detachably arranged on the back of the movable mold 2, and the core mold 3 is attached to the movable member 16.

接触したのち２は、型閉じしてキヤピティを形成する。Further, the film presser 18 has a shoulder portion 18a, and the shoulder portion 18a has a shoulder portion 18a.
The tip 18b is constantly pressed in the movable direction by a spring member 19 provided between the cutter rear end and the movable member 16.
It protrudes further and covers the cutting edge so that it can be moved in and out. Next, the automatic film insert will be explained. From the mold open state shown in FIG. 4, first, the movable member 16 is moved forward together with the core mold 3 to bring it into contact with the movable mold 2. At this time, the movable member 18b presses the long film 7a against the edge member 14 and fixes it on the movable side. The movable member 16 compresses the spring member 19, which is related to the holding of the long film 7a by the film presser 18, and moves further forward. As a result, the tip 18b is retracted into the movable member, and as the tip 18b is retracted, the cutting edge of the cutter 17 is exposed, and the Z long film 7a is punched out in a circular shape inside the edge member 14. This punching is performed by piercing the longest film 7a firmly fixed by the film presser 18 with a serrated cutting edge. For this reason, it is more reliable than in the case of push-cutting, and since it is carried out at the end face of the core, the punched cut film 7 is positioned at the end face of the movable part 3e of the core die 3, which is moving together with the movable part village 16. I'm going to do it. At this time, when the core end face is placed under reduced pressure, the cut film 7 is adsorbed 2 to the protruding die end face at the same time that punching is completed. Next, when the movable part 3e is retreated to the three-dimensional surface 4, it is inserted into the three-dimensional surface 4 formed by the core-shaped fixed part 3d, as shown in FIG. Further, after the movable member 16 comes into contact with the movable mold 2, the mold 2 closes to form a cavity.

is cut and held by suction on the core mold surface protruding from the movable mold 2. As mold closing progresses further, the spring member 2
4 is compressed, and the movable mold 2 comes to enter the insertion hole 26 of the mold receiving plate 27. At this time, the operating punch 30 contacts the fixed mold 1 and prevents the movement of the core mold 3 together with the movable plate 23.
Only the mold opening plate 20, pedestal 21, and movable mold 2 need to be moved.
The core mold 3 stops at that position. As a result, movable type 2
As the core mold 3 moves, the core mold 3 comes to be drawn into the movable mold, and when the movable mold 2 comes into contact with the fixed mold 1, the movable mold 2
The film 7 is inserted into the three-dimensional surface 4 of the cavity 5 formed by the fixed mold 1 and the fixed mold 1.

Moreover, since the film is not limited to a specific type, its application range is wide, and it has the advantage that it can be used to create patterns on three-dimensional surfaces.
