Description of the Related Art Films are sometimes adhered to the surface of various resin molded articles such as automobile parts for the purpose of improving the appearance and preventing damage. The same thing is often performed on plate materials such as panels made of metal and other materials other than resin molded products. The film is adhered to a molded product or a plate by vacuum molding, for example, and the film is formed from a peripheral portion or a hole of the molded product or the plate.
The film extends to unnecessary parts. Therefore, in order to complete the product, it is necessary to cut off unnecessary portions of the film, and this cutting operation is generally called trimming. The trimming has been conventionally performed by a trimming device including an upper die, a trimming blade provided on the upper die, and a lower die on which a molded product is placed as shown in, for example, JP-A-9-136298.

It is. For this reason, the trimming blade is usually slightly larger than the designed dimension of the end of the molded product in the case of outer trimming, and slightly smaller in the case of hole trimming. However, the resin molded product is warped due to molding conditions and the like, and dimensional accuracy variation due to deformation or shrinkage cannot be avoided. When trimming an unnecessary portion of a film adhered to such a molded product, the following problems may occur. For example, when trimming an unnecessary film on the outer peripheral portion of a molded product, a gap is generated between the trimming blade and the molded product terminal when the actual dimension of the molded product is smaller than the design dimension of the outer peripheral portion, and thereby, The film is left uncut and burrs occur. Therefore, in this case, it is necessary to perform a finishing operation by providing a post-processing step. On the other hand, if the dimensions of the actual molded product are larger than the design dimensions, the trimming blade contacts the molded product and damages the molded product, resulting in defective products. Conversely, in the case of hole trimming, if the actual molded product has holes larger than the design dimensions, uncut or burrs will occur, and if the actual molded product holes are smaller than the design dimensions, the molded products will be damaged. is what happened.

FIG. 1 shows a sectional structure of a film trimming apparatus according to the present invention. Reference numeral 1 denotes a lower mold on which the molded product W is placed, which is composed of a fixed receiving portion 2 and a movable receiving portion 3 having a shape matching the shape of the lower back surface of the molded product W. The movable receiving portion 3 is supported by an elastic member 4 such as a spring or a sponge. The molded article W is made of polypropylene, and an acrylic film F having a woodgrain pattern printed thereon is attached to an upper surface of the molded article W. Reference numeral 5 denotes an upper die, which is arranged at an upper position corresponding to the lower die 1 and
Is provided with a trimming blade 6. The trimming blade 6
Is from 0.1 to the design dimension of the outer peripheral end of the molded product W.
2.0mm outer circumference trimming blade 6A with a larger circumference
With respect to the design dimension of the end of the pocket hole of the molded product W.
A pocket trimming blade 6B having a shape smaller than the entire circumference of 1 to 2.0 mm is provided. Further, a stretchable sheet 7 made of polyethylene cloth is held and arranged below the outer peripheral trimming blade 6A and the pocket trimming blade 6B by a clamp (not shown). In the present embodiment,
The clamp is provided on a vertical movement table of a press device (not shown) to which the upper die 5 is attached, but may be provided directly on the upper die 5.

の成形品のフィルムトリミング工程が完了する。The process of actually performing trimming by using the thus configured apparatus will be described below. First, as shown in FIG. 1, the molded product W to which the film F is adhered is placed on the fixed receiving portion 2 and the movable receiving portion 3 of the lower die 1. Next, when the upper die 5 is lowered by driving a press device (not shown),
The outer peripheral trimming blade 6A, the pocket trimming blade 6B, and the sheet 7 provided thereunder reach the film F. When the upper die 5 is further lowered, the movable receiving portion 3 is pushed down and the film F is pulled as shown in FIG. Accordingly, the sheet 7 is sandwiched between the outer peripheral trimming blade 6A and the pocket trimming blade 6B and the molded product W terminal, and the sheet 7 descends while pressing the film F against the molded product W terminal. The film F is pulled by the sheet 7 while being pressed by the terminal of the molded product W, and is finally cut at the terminal of the molded product W. Thus, the film F is trimmed. As shown in FIG. 3, in the present invention, a clearance of 0.1 to 2.0 mm is provided between the trimming blade 6 and the end of the molded product W. However, since the sheet 7 enters the clearance, trimming is performed as a result. The same effect as when the clearance between the blade 6 and the molded product terminal W is zero can be obtained. That is, there is no occurrence of uncut portions or burrs of the film F and no damage to the molded product W. As described above, the film trimming process of the molded product for the switch panel of the automobile is completed.

ることが可能となり、生産性の向上に貢献する。As is clear from the above description, the film trimming apparatus of the present invention has a stretchable sheet below the trimming blade, and sandwiches the sheet in the clearance between the trimming blade and the molded product terminal during trimming. By doing so, the trimming is performed with the clearance of 0, so even if there is an error in the actual dimensions of the molded product with respect to the design dimensions of the molded product, no uncut or burr occurs, Do not damage the molded product. Therefore,
By employing the present invention for film trimming,
The post-processing step can be eliminated and the occurrence of defective products can be minimized, contributing to an improvement in productivity.
