[0012]

Embodiments of the present invention will be described in detail with reference to the drawings.

As an apparatus for manufacturing a molded article with a film according to the present invention, there is provided a mold for injection molding comprising a mold A and a mold B;
Unwinding roll means 2 for unwinding the film 1; film introducing means 3 for introducing the film 1 unwound from the unwinding roll means 2 between the mold A and the mold B; In the apparatus for manufacturing a molded article with a film comprising a film pressing means 4 for pressing around the cavity recess 6 on the surface of the mold A and a film heating means 5 for heating and softening the film 1, the film pressing means 4 has elasticity. One that can be inserted and removed between the mold A and the mold B integrally with the film heating means 5 via the connecting body 28 is exemplified.

The apparatus for manufacturing a molded article with a film according to the present invention basically comprises an injection mold, a film pressing means 4,
It comprises the film heating means 5, but may comprise the unwinding roll means 2 and the film introduction means 3 as described above.
When the film 1 is manually introduced into the injection molding die, the unwinding roll means 2 and the film introducing means 3 become unnecessary.

The mold for injection molding comprises a mold A having a cavity 6 in which the film 1 is pressed by a film pressing means 4 described later, and the film 1 is in close contact with a vacuum suction force, and a mold B. Become. The resin injection port 9 may be formed in the mold A or may be formed in the mold B. When the resin injection port 9 is formed in the mold A, the resin injected from the film 1 that is in close contact with the mold A at a location different from the cavity recess 6 breaks through and moves to the mold B. (See FIG. 11).

A film cutting means 11 for dividing the film 1 may be formed on the upstream side of the cavity 6 of the mold A. In this case, the film cutting means 1 of the mold B
1, the film cutting means 11 at the time of closing the mold.
May be formed with a storage recess 12 for storing the data. Examples of the film cutting means 11 include a cutter and a hot-melt cutting device (heat cutter).

A film end clamping means 13 for fixing the film end 10 may be formed on the downstream side of the cavity recess 6 of the mold A. In this case, at a position corresponding to the film end clamping means 13 of the mold B,
A storage recess 12 for storing the film end clamping means 13 when the mold is closed may be formed.

A vacuum suction port 15 for bringing the film 1 into close contact with the surface of the mold A may be provided on the inner surface of the cavity 6 of the mold A or on the parting surface 14 of the mold A.

On the surface of the mold A of the injection mold,
A seal groove 16 may be formed on the die surface between the location where the film 1 is pressed by the film pressing means 4 and the cavity (see FIG. 10). The seal groove 16 has a width of 1 to 5 mm and a depth of 0.5 to 5 mm.
The film 1 corresponding to the seal groove 16 is formed so as to bite into the seal groove 16, and the film pressing means 4 is formed.
Even when the film 1 moves upward integrally with the film heating means 5, the film 1 is caught by the seal groove 16, so that the film 1 can be hardly lifted from the surface of the mold A. A vacuum suction hole may be formed at the bottom of the seal groove 16 to reliably prevent the film 1 from rising.

The unwinding roll means 2 is formed by winding the film 1 in a roll shape, and includes a mold A for injection molding.
The film 1 is continuously supplied between the mold 1 and the mold B. The film 1 unwound from the unwinding roll means 2 is grasped by the film introducing means 3 and the like, and is introduced between the mold A and the mold B via a guide roll or the like. The unwinding roll means 2 is always subjected to a force (so-called back tension) for rotating in the direction opposite to the unwinding direction so that the film 1 is not unwound excessively and the film 1 does not undulate. I have.

The film introducing means 3 is for introducing the film 1 unwound from the unwinding roll means 2 between the mold A and the mold B, and includes, for example, a pinch means 17 and a driving means 18. There is something consisting of. The pinch means 17 is for grasping the end of the film 1. The pinch means 17 is attached to the drive means 18. The drive means 18 reciprocates the pinch means 17 between the upstream side and the downstream side of the cavity recess 6. As an example of the driving unit 18, there is a type in which the rotation of a motor such as a stepping motor or a servo motor is linked to the rotation of the ball screw 27, and the rotation of the ball screw 27 causes the pinch unit 17 to move up and down. . Since the motor and the like constituting the driving means 18 can finely adjust the forward / reverse rotation and rotation speed of the motor, the film introduction means is used to position the film 1 at an accurate position on the cavity 6 of the mold A. 3 can be performed.

In the present invention, the film pressing means 4 can be integrated with the film heating means 5 via the elastic connecting member 28 so as to be able to enter and exit between the mold A and the mold B. The film heating means 5 and the film pressing means 4 are combined so that the interval can be changed by the elastic force of the connecting body between the two means, and enter between the mold A and the mold B, It comes out from between the mold A and the mold B.

The film presser 4 presses the film 1 introduced between the mold A and the mold B around the cavity 6 of the mold A. The film pressing means 4 may be a single-shaped plate corresponding to a part of the periphery of the cavity concave portion 6 or may be a U-shaped plate. On the upstream side of the film holding means 4, a film cutting means 11 for dividing the film 1 may be formed. Further, the surface of the film holding means 4 which contacts the mold A may be coated with a fluororesin. This is to prevent the film holding means 4 and the film 1 from sticking to each other even if the surface temperature of the film holding means 4 rises.

Further, a sealing elastic member 29 made of rubber, silicone, fluorine or the like may be formed on the surface of the film holding means 4 which contacts the mold A (see FIG. 15). The sealing elastic member 29 is also called an O-ring or the like. Instead of being formed on the film pressing means 4, it may be formed on the surface of the mold A (see FIG. 16). This is because the airtightness of the space between the film 1 and the mold A is improved when the film 1 is pressed around the cavity concave portion 6 of the mold A and suctioned by vacuum.

The film heating means 5 heats the film 1 introduced between the mold A and the mold B and covering the cavity 6. When the film 1 is brought into close contact with the inner surface of the cavity 6 of the mold A by vacuum suction, the film heating means 5 is designed to easily adhere to the fine irregularities of the inner surface of the cavity 6 and the sharp corners. The film 1 is softened in advance. Examples of the film heating means 5 include a device made of a heated iron plate 19, a device made of a far-infrared heater, and a hot air blower. On the back surface of the film heating means 5, a molded product 24 with a film obtained in the pre-molding cycle and adhered to the mold B (FIG. 9)
A molded product removal device with a film for peeling the molded product from the mold B and removing the molded product from the mold A and the mold B may be provided. As an apparatus for removing a molded article with a film, there is an apparatus provided with molded article holding means such as a suction cup 20.

Film holding means 4 and film heating means 5
Are integrated with each other via a connecting body 28 having elasticity. The connecting body 28 is made of a means capable of changing the distance between both means by elastic force. For example, there are a spring, an air damper, an oil damper, and an air cylinder. For this reason, the film holding means 4 is
Even if the angle and the interval between the film pressing means 4 and the film heating means 5 are slightly shifted by pressing the connecting member 28, the connecting body 28 absorbs the shift. Therefore, the film 1 can be pressed by the film pressing means 4 around the cavity 6 of the mold A with a uniform pressure. The connecting body 28 may be made of a heat insulating material. This is to prevent excessive heat from being transmitted to the air cylinder constituting the connecting body 28, thereby damaging the air cylinder and preventing the film pressing means 4 from being heated and expanded unnecessarily.

The film pressing means 4 or the film heating means 5 is attached to the driving means 22. Drive means 22
The upper part of the mold A and the mold B and the mold A
And the mold B are reciprocated. As an example of the driving unit 22, the rotation of a motor such as a stepping motor or a servomotor is linked with the rotation of a ball screw, and the rotation of the ball screw is
It is conceivable that the unit formed by combining the film heating means 5 with the film heating means 5 may be moved up and down, left and right, and back and forth. The stepping motor and the like constituting the driving means 22 can finely adjust the forward / reverse rotation and rotation speed of the motor. It is preferable that the driving means 22 is directly attached to the film heating means 5 and not directly attached to the film holding means 4.
This is because the angle deviation between the film holding means 4 and the film heating means 5 cannot be absorbed by the connecting body 28 between the film holding means 4 and the film heating means 5.

As the film 1, a film in which a picture layer, an adhesive layer, and the like are sequentially laminated on a long base sheet is applicable. The design layer is a layer that imparts decorativeness and functionality to the surface of the molded product 25. The pattern layer includes a normal printed pattern and a conductive pattern formed of a conductive material. The adhesive layer
This is a layer for bonding the film 1 and the molded product 25. The film 1 may be a sheet-like film trimmed into a predetermined shape. In the following description, a case will be described in which the film 1 whose upstream side is wound around the unwinding roll means 2 and whose downstream side is the end portion 10 of the film is used.

A method for manufacturing a molded article with a film according to the present invention will be described using the apparatus for manufacturing a molded article with a film and the film 1 described above. First, the film 1 is introduced by the film introducing means 3 to a position where the film 1 covers the cavity recess 6 of the mold A. For example, the following may be performed. First, the end 10 of the film is pinched by the pinch means 17 of the film introduction means 3.
(See FIG. 1). Grab the edge of the film 1
It is also possible to grab a little above zero or just grab the edge 10 of the film. Next, the pinch means 17 holding the end 10 of the film by the drive means 18 of the film introduction means 3 is moved to the downstream side of the cavity recess 6 of the mold A (see FIG. 2). By moving the pinch means 17, the picture of the film 1 is positioned in front of the cavity 6 of the mold A. It is preferable that the film 1 is positioned at an accurate position on the cavity concave portion 6 by interlocking the driving means 18 with the positioning sensor. Next, the film end 10 is fixed to the film end clamping means 13.
Next, the film 1 grasped by the pinch means 17 is released. Next, the pinch means 17 is pulled out from between the mold A and the mold B by the drive means 18. The film 1 is gripped again by the pinch means 17 of the film introduction means 3 on the film cutting means 11 formed on the upstream side of the cavity 6 of the mold A (see FIG. 3).

Next, the film pressing means 4 and the film heating means 5 are integrally introduced between the mold A and the mold B. Specifically, instead of operating the film pressing means 4 and the film heating means 5 separately, the connecting body 2 is driven by the driving means 18 attached to the film heating means 5.
8, the film pressing means 4 and the film heating means 5 are integrated and introduced between the mold A and the mold B (FIG. 4).
reference).

Next, the film is moved toward the mold A by pressing the film around the cavity 6 of the mold A by the film pressing means 4, and the pressing strength of the film 1 is increased by the elasticity of the connecting body. The angle is adjusted, and the film 1 is heated by the film heating means 5,
Vacuum suction is applied between the mold A and the film 1 to bring the film 1 into close contact with the inner surface of the cavity 6 of the mold A (FIG.
See FIG. 6). Specifically, the film holding means 4 and the film heating means 5 are integrally moved by the driving means 22 attached to the film heating means 5 toward the mold A, and the cavity recess 6 of the mold A is Film 1 around
Press. Although the film pressing means 4 and the film heating means 5 are united, even if a deviation in angle or interval occurs between them, the deviation can be absorbed by the elastic force of the connecting body 28 between them. Therefore, even if the periphery of the cavity 6 of the mold A is inclined, the film 1 can be pressed down without any gap. The pressing strength is 18
0 g / cm 2.

The heating by the film heating means 5 may be started simultaneously with the start of the movement of the film holding means 4 toward the mold A. Further, since the film holding means 4 and the film heating means 5 are combined so as to generate an elastic force and change the interval, the film holding means 4 and the film heating means 5 are combined.
After pressing the film 1 once, the pressing force can be further increased and the heating means can be brought closer to the film 1. That is, the pressing strength of the film pressing means 4 is proportional to the degree of heating of the film 1 by the heating means. Therefore, the film 1 can be heated more efficiently and without displacement of the film 1.

Incidentally, the film 1 may be cut by the film holding means 4 and cut upstream of the cavity 6 (see FIG. 5). The vacuum suction may be performed by sucking the film 1 from a vacuum suction hole formed on the inner surface of the cavity 6 of the mold A or the parting surface 14. The space between the film holding means 4 and the film heating means 5 may or may not be sealed. At this time, when the seal groove 16 is formed on the surface of the mold A of the injection mold between the place where the film 1 is pressed by the film pressing means 4 and the cavity recess 6, The seal groove 16
It is preferable to form the portion of the film 1 corresponding to (1) so as to bite into the seal groove 16 (see FIG. 10). Thus, even if the film pressing means 4 moves upward integrally with the film heating means 5, the portion of the film 1 which is formed so as to bite into the seal groove 16 is caught, and the film 1 becomes a mold. A can be prevented from easily floating from the surface of A.

Next, the film pressing means 4 is moved to the mold A by moving the film heating means 5 toward the mold B.
The mold holding means 4 and the film heating means 5 are integrated with the mold A and the mold
(See FIG. 7).

In the case where the film holding means 4 has a portion in contact with the film 1 coated with a fluororesin,
When the film holding means 4 is pulled away from the periphery of the cavity 6 of the mold A, the film holding means 4 and the film 1 can be prevented from sticking. Even if the temperature of the film pressing means 4 is raised to, for example, 80 ° C., the adhesion between the film pressing means 4 and the film 1 can be prevented.

Next, the mold A and the mold B are closed, and the film 1 and the mold B, which are in close contact with the cavity 6 of the mold A, are closed.
The molten resin 23 is injected into the space between the mold A and the mold B (see FIG. 8). Then, the mold A and the mold B are opened, and the molded product 24 with the film is formed between the mold A and the mold B. Remove from between (see FIG. 9). Specifically, the mold A and the mold B are closed, the film 1 is sandwiched, the molten resin 23 is injected from the resin injection port 9, and the molten resin 23 is melted while the adhesive layer of the film 1 is in contact with the molten resin 23. The resin 23 is cooled and solidified, and the film 1 adheres to the molded product 25 (see FIG. 8). When a so-called transfer film is used as the film 1, the base sheet is peeled off after the film 1 and the molded product 25 are integrated. The molten resin 23 may be directly injected from the resin injection port 9 of the mold B into a space between the film 1 and the mold B that is in close contact with the cavity recess 6 of the mold A. Alternatively, the molten resin 23
The resin may be injected from the resin injection port 9 of the mold A (see FIG. 11). In other words, the injection port is provided in the mold A at a location different from the cavity concave portion 6, and the film 1 adhered to the mold A is provided.
, The molten resin 23 is moved toward the mold B, and then the film 1 adhered to the cavity recess 6 of the mold A.
It is preferable to inject into the space between the mold and the mold B (see FIG. 11). As a material of the molten resin 23, a polystyrene resin, an ABS resin, a polycarbonate resin, a polypropylene resin, a polyethylene resin, or the like can be used. Finally, the film edge clamping means 13
Is separated from the mold, and the fixed mold and the movable mold are opened.
The molded product 24 with the film is separated from the mold A and opened while being fixed to the mold B.

When the mold A and the mold B are opened, the molded product 24 with a film may be left in the mold B (see FIG. 9) or may be left in the mold A. Is also good. In the case where a molded article removal means with a film such as a suction cup 20 is provided on the back surface of the film heating means 5, the heating of the film 1 on the mold A side by the film heating means 5 is completed. The molded product with film 24 attached to B is sucked by the suction cup 20 and the film heating means 5 is drawn out from between the mold A and the mold B, and the molded product with film 24 is taken out. You may.
