The shallow grooves 8, 8 having lower surface openings are erected from corners formed by the inner surface of the outer edge and the upper end of the inner surface of the side plate hanging from the other outer edge of the top plate.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Referring to the drawings, reference numeral 1 denotes a transparent synthetic resin lid body having a pattern 2 provided by insert molding on the inner surface of a top plate 3, which hangs a peripheral wall from an outer periphery of the top plate 3, and a top plate as a part of the peripheral wall. From the rear portions of the left and right side walls 4a, bearing plates 6, 6 having bearing holes 5, 5 are hung downward.
[0009]
As shown in FIGS. 1 to 3, the lid has a gate mark 7 on the lower part of the rear surface of the top plate 3 in the middle in the left-right direction or on the rear wall 4 b as a part of the peripheral wall, and the top plate has a flat upper surface. The inner surface is formed as a curved surface with both front and rear portions being low and the middle portion being high. Further, as shown in FIG. 3, a shallow groove 8 having an opening on the lower surface is erected from the corner on the outer periphery of the inner surface of the top plate 3. Reference numeral 9 denotes a film with a pattern 2 attached to the lower surface of the top plate 3 by insert molding, and the outer peripheral surface of the film forms the inner wall of the above-mentioned shallow groove. The film may be a transfer film.
[0010]
The lid 1 is formed as shown in FIG.
[0011]
In FIG. 5, reference numeral 11 denotes a fixed mold, 12 denotes a movable mold, and 13 denotes a core mold as a part of the movable mold. On the separation surface 14 between the fixed mold 11 and the movable mold 12, a cavity 15 for forming a top plate of a lid is formed on the fixed mold side, and the outer periphery of the top plate is formed on the movable mold 12 side. A space 16 for forming the bearing wall 6 and a peripheral wall which is hung down therefrom are formed. A vacuum passage 17 is formed in the outer periphery of the upper surface of the core mold 13 and formed along the lower surface and side surfaces of the core mold. The upper surface of the core mold 13 and the inner edge of the cavity 16 for forming the peripheral wall and the like are formed. The upper surface of the movable mold part therebetween forms an inner wall forming surface 18 of the molded product, and from the outer periphery of the inner wall forming surface 18, a ridge 19 is erected in a tubular shape, and the ridge 19 surrounds the inner wall forming surface 18. While the patterned film 9 for insert molding is placed and the film 9 is sucked by the vacuum passage 17, only the sheet may be peeled off after being transferred to the inner surface of the lid top plate.
[0012]
Reference numeral 19 denotes a gate, which is formed in the movable mold separating surface 14 in the middle in the left-right direction at the rear of the lid forming cavity 15.
[0013]
In the mold-clamped state shown in FIG. 5, a transparent or translucent molten resin material is injected into the cavity 15 and the space 16 so that the transparent or translucent lid having the pattern 2 on the inner surface of the top plate as described above. Since 1 is formed, the mold may be opened and the molded product may be taken out.
[0014]
At the time of injection of the molten material, the projecting ridge 19 that rises in a tubular shape from the outer periphery of the inner wall forming surface 18 is formed by the patterned resin film 9 fitted into the tubular projecting ridge, and the molten resin material injected from the gate 20. And prevents the gate-side end from being turned up, and ensures insert molding on the inner surface of the top plate 3.
[0015]
In the illustrated example, the cylindrical ridge 19 is erected from the entire circumference of the inner wall forming surface 18, but may be provided only on the side facing the gate 20, that is, only on the right end of the inner wall forming surface 18 in the illustrated example. Alternatively, it may be raised only from the outer edge portion of the inner wall forming surface on the side facing the inner wall forming surface side on the gate side, that is, only the left end edge of the inner wall forming surface 18 in the illustrated example. In the former case, the molten resin material is directly injected with respect to the gate-side end face of the film, thereby preventing the film from being displaced or turned up, and in the latter case, on the downstream side of the molten material flow, The end face of the film is supported to prevent its displacement. Further, although the gate 20 is provided on the rear surface side of the lid 1, it can be provided on the side surface or the front surface.
[0016]
In the above embodiment, the lid is described. However, the lid may be formed in the same manner even with a base hanging down from the outer periphery of the top plate to the peripheral wall. In this case, the bearing plate 6 with the bearing hole 5 is omitted.
[0017]
【The invention's effect】
The present invention has the above-described configuration, and by adopting the configuration described in each claim, a lid having a pattern on the inner surface of the transparent or translucent top plate 3 can be formed. Since it is seen through, it can be seen as a deep pattern, and its decorativeness can be enhanced. Also, since the pattern is provided on the inner surface of the top plate, it is less likely to directly touch other objects, so that the pattern does not fade or peel due to friction. In addition, since the shallow groove 8 is provided, the insert molding of the patterned film 9 on the inner surface of the top plate 3 becomes easy.
