DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device and a method for manufacturing an insert molded product used for front panels and buttons of AV equipment, instrument panels of automobiles, and the like.

<Technical Background> Conventionally, as a method of obtaining a three-dimensional insert material for integrating with an injection molded product, there is a method of narrowing a flat insert material to a concave surface of a preform means. However, since the stretch ratio of the portion where the printed pattern is formed becomes large, the thickness of the portion becomes thin,
There was a problem that the pattern was easily uneven and the pattern was distorted or transparent. Therefore, there is a so-called convex drawing method in which a painting insert material is coated on the convex surface of the preform means so that the stretch ratio of the portion where the printed pattern is formed may be small.

Since it is brought directly into the mold, there are adverse effects such as accumulation of cutting dust inside the injection mold and adhesion of cutting dust to the molded product. Further, due to the above (2), the three-dimensional insert material mounted on the male mold of the injection mold from the convex surface must be jumped to the cavity concave surface of the female mold by the molding resin injected from the male mold. At this time, the position at which the three-dimensional insert jumps is displaced, causing a positional shift, and deformation of a part of the three-dimensional insert material that is to be contacted with the molding resin.

Next, a method of manufacturing an insert molded product will be described. First, the three-dimensional insert material is obtained by covering the convex surface of the preform means 10 with the flat insert material 7.

As the flat insert material 7, there is a painting material in which a pattern layer 72, an adhesive layer 73 and the like are sequentially formed on a base sheet 71 (see FIG. 11). Base sheet 71
Is used as a base film or a base sheet of an ordinary insert material, and includes an acrylic sheet, a plastic film such as polyethylene terephthalate, and the like. The pattern layer 72 is formed on the surface of the three-dimensional molded product 60 to form a pattern, a picture, a logo, a character, a blank character, a symbol, etc.
It is formed by a normal forming method such as printing using a translucent ink or a light-shielding ink. The design layer 72 may have a metal layer formed by vacuum evaporation. Adhesive layer 73
Is for bonding the insert material 7 to the surface of the three-dimensional molded product 60 at the same time as the molding of the three-dimensional molded product 60. Formed by the method.

The preform of the flat insert 7 is preferably performed by using the preform means 10 described above. To facilitate preforming, the insert material 7 may be heated and softened using a heating means during preforming.
Also, by cutting the peripheral edge 61 and the like of the three-dimensional insert material 70,
Unnecessary parts may be trimmed. Trimming may be performed by the trimming means described above.

Next, part or all of the outer surface of the three-dimensional insert 70 is removed from the convex surface while being held by the first transport means 20 (see FIG. 2). The holding may be performed by the three-dimensional insert material convex side holding means or the like comprising a suction cup or a vacuum suction means. The holding portion may be the entire convex surface side of the three-dimensional insert material 70 or may be a part. Second
The transfer to the transfer means 30 may be performed by the movable arm 21 or the like.

Next, a part or all of the inner surface of the three-dimensional insert material 70 held by the first transfer means 20 is removed from the first transfer means 20 while being held by the second transfer means 30, and the injection molding die 1 3D insert material 7
The convex surface of No. 0 is fitted into the concave surface of the cavity of the injection mold 1. (See FIGS. 3 to 7). The holding may be performed by the three-dimensional insert material concave side holding means 32 or the like including a suction cup or a vacuum suction means. The holding part may be the entire concave side of the three-dimensional insert material 70 or a part thereof. The transfer to the injection mold 1 may be performed by the movable arm 31 or the like.

For example, the movable arm 31 is moved, and the three-dimensional insert material convex side holding means 22 of the first transport means 20 is moved.
And the three-dimensional insert material concave side holding means 32 of the second transport means 30 are overlapped, and the three-dimensional insert material 70 may be transferred from the first transport means 20 to the second transport means 30 (FIGS. 3A and 3B). ) (C)). Next, the second transport means 30
Is rotated toward the concave surface of the cavity of the injection mold 1. That is, when the convex portion 150 of the preform means 10 and the cavity forming concave surface 6 of the injection mold 1 are arranged at right angles, 90
(See FIG. 4). When the convex part 150 of the preform means 10 and the cavity forming concave surface 6 of the injection molding die 1 are arranged in parallel, they are rotated by 180 degrees. Next, the movable arm 31 is moved to face the cavity forming concave surface 6 of the female mold 3 in the injection mold 1 (see FIG. 5).
If necessary, the cavity is formed by the insert molded product taking-out means 33 (see FIGS. 5, 6, and 7) provided on the back surface of the three-dimensional insert material concave side holding means 32. In order to hold the insert molded product 100 of the previous cycle remaining on the convex surface 5 and prepare for the next transport, the second transport means 30 is retracted from the inside of the injection mold 1 (see FIG. 7).

Since the three-dimensional insert material 70 has already been preformed so as to substantially match the cavity-forming concave surface 6 of the female mold 3, the cavity-forming concave surface 6 of the female mold 3 or the cavity-forming convex surface 5 of the male mold 2 is formed. It can be mounted at a predetermined position simply by fitting it.

Next, the injection molding die 1 is closed and injection molding is performed to integrate the three-dimensional insert material 70 with the injection molded product (FIGS. 8 to 10). That is, the male mold 2 and the female mold 3 are closed to form the cavity 8 (see FIG. 8), the molding resin 9 is injected from the resin injection port 4 into the cavity 8 (see FIG. 9), and the three-dimensional molded product 60 is formed. After the cooling and solidification, the insert molded product 100 (see FIG. 10) in which the three-dimensional insert material 70 is formed on the surface of the three-dimensional molded product 60 is taken out from the injection molding die 1. The removal of the insert molded product 100 may be performed by the insert molded product removal means 33 provided on the back surface of the three-dimensional insert material concave side holding means 32 or the like.

By the heat of the molding resin 9 at the time of injection,
The adhesive layer 73 of the three-dimensional insert material 70 is melted, and as the molding resin 9 cools and solidifies, the adhesive layer 73
Glue to the 0 surface. Examples of the molding resin 9 include an acrylonitrile styrene resin, a polycarbonate resin, a polystyrene resin, an acrylic resin, and a polyester resin.

Practical Example 1 (FIGS. 12 to 18) First, a three-dimensional insert material 70 is obtained by coating the flat insert material 7 on the convex surface of the preform means (see FIG. 13). In other words, the planar insert material 7 is sandwiched between the frame-shaped clamps 13, and the upper and lower surfaces of the planar insert 7 are heated by the upper heating means 16 and the lower heating means 160 constituting the heating means. I do. After retracting the upper surface side heating means 16 and the lower surface side heating means 160, the frame-shaped clamp means 13 with the flat planar insert material 7 sandwiched therebetween is moved downward, and the flat insert material 7 is removed.
Is pressed against the convex portion 150 of the core mold 15 and suctioned by a vacuum suction means to form a three-dimensional shape (see FIG. 14).
Then, the peripheral edge 6 of the three-dimensional portion is
Trim 1 The flat insert 7 has a peripheral edge 61.
Is separated into a three-dimensional insert material 70 and an unnecessary part 701 (see FIG. 15). Separated unnecessary part 70
1 may be removed at this stage or at a later stage. Thereafter, the clamping means 13 is opened to release the pressing of the insert material (see FIG. 16).

Next, part or all of the outer surface of the three-dimensional insert material is removed from the convex surface while being held by the first transport means (see FIGS. 12 and 13). That is, the movable arm 21 of the first transporting means 20 is tilted sideways from the base, and the three-dimensional insert material 70 is held by the suction cup of the concave part of the three-dimensional insert material convex side holding means 22 (see FIG. 12). Next, the movable arm 21 is raised to stand upright (see FIG. 13). The angle of only the three-dimensional insert material convex side holding means 22 may be adjusted while the movable arm 21 is kept upright. Simultaneously, the next preform of the planar insert material 7 may have been started by the preform means 10 (see FIG. 13).

Next, a part or all of the inner surface of the three-dimensional insert 70 held by the first transfer means 20 is removed from the first transfer means 20 while being held by the second transfer means 30. The second transport means 30 is movable along the movable rail 40. Further, the movable rail 40 itself can also be translated. Further, the three-dimensional insert material concave side holding means 32 of the second transport means 30 may move together with the movable arm 31, or only the three-dimensional insert material concave side holding means 32 may move away from or approach the movable arm 31. It may be movable so that it can be provided, or may be provided rotatably. Therefore, the three-dimensional insert material concave side holding means 32 of the second transport means 30 can move in any direction such as up, down, left, right, forward and backward. That is, the second transporting means 30 is moved closer to the first transporting means 20 along the movable rail 40, and the three-dimensional insert material concave side holding means 32 of the second transporting means 30 is replaced with the three-dimensional insert material convex side holding means of the first transporting means 20. 22 (FIG. 14).
Three-dimensional insert material convex side holding means 2 of first transport means 20
In addition to weakening the suction force of the two-dimensional insert material 70 on the three-dimensional insert material 70 and increasing the suction force of the three-dimensional insert material concave side holding means 32 of the second transport means 30 on the three-dimensional insert material 70, the three-dimensional insert material 70 and the unnecessary portion 701
(See FIG. 15).

Next, it is conveyed into the injection molding die, and the convex surface of the three-dimensional insert material is fitted into the cavity concave surface of the injection molding die (see FIG. 17). That is, the second conveying means 30 holding the three-dimensional insert material 70 and the unnecessary portion 701 is moved closer to the female mold 3 of the injection molding die 1 along the movable rail 40. After the position of the second transport means 30 has passed the position of the female mold 3, the movable rail 40 itself is moved in parallel to position the second transport means 30 in front of the female mold 3 (see FIG. 16).
Before moving the movable rail 40 itself, the unnecessary portion 7 of the film is reduced by weakening the attraction force of the second transport means 30 or the like.
Only 01 is removed from the concave surface side holding means 32 of the three-dimensional insert material. The removed unnecessary portion 701 is accommodated in a recovery container 702 below. Then, the three-dimensional insert material 70
The second conveying means 30 holding only the movable member 40 is moved closer to the female mold 3 of the injection molding die 1 along the movable rail 40, and the three-dimensional insert material 70 is fitted into the cavity forming recess 6. The three-dimensional insert material is reduced by weakening the attraction force of the three-dimensional insert material convex side holding means 32 of the second transport means 30 to the three-dimensional insert material 70 and increasing the attraction force of the cavity forming recess 6 of the female mold 3 to the three-dimensional insert material 70. 70 (see FIG. 17).

Next, the three-dimensional insert material 70 and the injection molded product are integrated by closing the injection mold and performing injection molding (see FIG. 18). That is, the male mold 2 and the female mold 3 are closed with the three-dimensional insert material 70 interposed therebetween, and the molding resin 9 is injected into the cavity 8. An insert molded product obtained by integrating the three-dimensional insert material and the injection molded product can be obtained.

[0036]

According to the present invention, the following effects are obtained because of the above-described configuration and operation. (1) In the present invention, since two separate transporting means are provided independently of the female mold constituting the preform means and transported, the preform operation, the transporting operation, and the fitting operation are performed by the respective means. Can be shared.
Therefore, since the conveying means is lightweight, a high-output driving device or a complicated and expensive device is not required, and the structure of the female mold itself constituting the preform means is simplified. Also,
Since the three-dimensional insert material is switched from the female mold constituting the preform means to the first transport means and the second transport means, it is difficult to directly bring the cut dust of the film adhered to the preform means into the injection mold. Therefore, adverse effects such as accumulation of cutting dust inside the injection mold and adhesion of cutting dust to the molded product are extremely reduced.

(2) According to the present invention, since two separate transporting means separate from the female die constituting the preform means are provided and transported, the three-dimensional insert material is injected from the convex surface of the preform means. It can be mounted on the concave surface of the cavity of the molding die. Therefore, there is no need to jump the three-dimensional insert material to the concave surface of the cavity by the pressure of the injected molding resin. Therefore, no displacement of the three-dimensional insert material and no deformation or deformation of the part of the three-dimensional insert material that is applied to the molding resin occur.
