Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a one-piece seat cover clamp structure.

[Prior Art] Conventionally, when molding a seat cushion of this type, for example, a vehicle, after setting the molding seat cover 4 along the mold surface 3 of the molding mold 2, the mold is closed and the foam for the main pad urethane home is formed. The agent is injected, foamed and cured to be integrally molded. To set the molded sheet cover 4 on the mold surface 3 so as not to wrinkle, four peripheral edges 5a formed on the four circumferences of the molded sheet cover 4, As means for fixing 5b to the molding die 2, for example, by attaching to the mounting surface 2a such as an inclined surface or a curved surface formed on the four sides of the die surface 3 with an adhesive tape 6 as shown in FIG. As shown in FIG. 8, needles or nail-shaped locking members 7 are planted in a protruding shape so that the four peripheral edges 5 can be pierced at a predetermined interval on the mounting surface 2a such as an inclined surface or a curved surface, and the same edge 5 is formed. It was fixed by piercing.

[Problems to be Solved by the Invention] However, when the four peripheral edges 5 are fixed to the pressure-sensitive adhesive tape 6, it is difficult to stick the mold 2 to the mold 2 because a mold release agent is applied during molding. There is a problem that the mounting surface 2a is peeled off, and when the fixing member 7 is pierced and fixed, it is difficult to fix the peripheral edge 5 along the mounting surface 2a, which may cause floating or wrinkling. In addition, there is a problem in that the locking member 7 causes scratches on the surface of the molded sheet cover 4, and in the case of both, if wrinkles are generated during fixing, it takes a great deal of time to fix them again. There was a problem.

The present invention has been made to solve the above-mentioned conventional problems, and a clamp structure for an integrally molded seat cover that can easily fix the four peripheral edges of the molded seat cover and can easily deal with wrinkle correction. It is intended to be provided.

[Means for Solving the Problems] In order to solve the above technical problems, the present invention provides an integrally molded seat cover clamp structure in which four peripheral edges of a molded seat cover are detachably fixed and set in a molding die. An inclined pressing support surface is formed continuously on the mold surface of the molding die, and the pressing support surface is provided with a retracting means capable of retracting a pressing plate corresponding to the four peripheral edges to clamp the four peripheral edges. It exists in the integrally molded seat cover clamp structure having the above-mentioned configuration.

[Operation] With the above configuration, the four peripheral edges of the molded sheet cover can be pressed substantially uniformly by the pressing plate,
Even when wrinkles occur, the pressing plate can be separated from the pressing support surface.

[First Embodiment] Next, a first embodiment of the present invention will be described with reference to FIGS. 1 to 3. In the drawings, 11 is a molding die, and the molding die 11 is an upper die 12 and a lower die. The lower mold 13 is provided with a mold surface 14 for molding a seat cushion of a vehicle seat, for example. A pressing support surface 16 is formed between the pressing support surfaces 16 for fixing the four peripheral edges 5a, 5b ... Of the molded sheet cover 4, and the pressing support surface 16 is formed.
Is provided with a holding device 17 at a position corresponding to each of the four peripheral edges 5a, 5b ... Of the molded sheet cover 4. The pressing device 17 is composed of a pressing plate 18 and tension springs 20 attached to both ends of the plate 18 and pulling the plate 18 toward the pressing support surface 16 side.
8 is formed in the shape of a strip plate having a length capable of pressing the respective peripheral edges 5a, 5b, ... Of the molded sheet cover 4, and a handle 19 is attached to the center thereof. Further, the tension spring 20 serves as a retracting means for retracting the pressing plate 18 so as to be able to contact the pressing support surface 16, has a predetermined spring pressure, and one end thereof can fix the peripheral edge 5 of the pressing support surface 16. It is fixed to the bottom portion 22 of the recessed portion 21 provided at intervals, and the other end portion is fixed to the left and right end portions of the pressing plate 18, and the pressing plate 18 is fixed to the pressing support surface 16 by a predetermined spring pressure by this tension spring 20. By pressing and contacting in a substantially close contact state, and by holding the handle 19 of the pressing plate 18 against the tension spring 20 and lifting it, the peripheral edges 5a, 5b ... Of the molded sheet cover 4 are inserted between the pressing support surface 16. A gap t is formed which allows the gap 19 to be released, and when the grip 19 is released, the restoring force of the tension spring 20 causes the peripheral edges 5a, 5b ... Between the pressing plate 18 and the pressing support surface 16.
Can be sandwiched.

Since the present embodiment is configured as described above, when setting the molded sheet cover 4, the sheet cover 4 is moved along the mold surface 14 by hand and without wrinkling, and each peripheral edge is set. 5a, 5b, ... Are sandwiched between the pressing plate 18 of each device 17 and the pressing support surface 16. Thereafter, a urethane foam material is injected into the lower mold 13, the mold is closed by the upper mold 12, and foaming and curing are performed inside, so that the pad material 23 is formed integrally with the seat cover 4.

As described above, when the seat cover 4 is set, the peripheral edges 5a, 5b, ... Can be easily set by lifting the pressing plate 18 of the pressing device 17 and inserting it between the pressing support surface 16. It can be set in a shorter time than the conventional set man-hours. Further, the molded product can be easily removed, can be repeatedly used, and the seat cover 4 is not damaged. In addition, if wrinkles are found after the setting, wrinkles can be easily removed by lifting the pressing plate 18 at a position near the wrinkles or where wrinkles are easily removed.

[Second Embodiment] Next, a second embodiment of the present invention will be described with reference to FIG. 4 and FIG.
In place of the tension spring 20 in the embodiment, a magnet 25 is embedded in the same plane as the pressing support surface 16 along the pressing support surface 16 formed on the four sides of the mold surface 14, and the pressing plate 18 is caused by the magnetic force of the magnet 25. Is fixed, and other configurations are similar to those of the first embodiment. Therefore, the pressing plate 18 is attachable to and detachable from the magnet 25, and has the same effect as that of the first embodiment.

In addition, the magnet 25 in the second embodiment has the pressing support surface 1
6, the holding plate 18 can be retracted and fixed, and the peripheral edges 5a, 5b ... Can be embedded at predetermined intervals so as to be sandwiched. Further, in the first and second embodiments, the pressing support surface 16 is illustrated as an inclined flat surface, but the present invention is not limited to this, and may be, for example, a curved surface that bulges outward. In this case, the pressing plate 18 is used. Is preferably provided in a curved surface shape following the same curved surface.

[Effects of the Invention] The present invention has an integrally molded seat cover clamp structure in which four peripheral edges of a molded sheet cover are detachably fixed and set in a molding die, and the molded sheet cover is continuously connected to the molding surface of the molding die. A seat cover set is formed by forming an inclined pressing support surface, and providing the pressing support surface with retracting means capable of retracting the pressing plate corresponding to the four peripheral edges to sandwich the four peripheral edges. At this time, the peripheral edge can be easily set by lifting the pressing plate of the pressing device and inserting it between the pressing plate and the pressing support surface, so that it can be set in a shorter time than the conventional setting man-hour. Further, the molded product can be easily removed, can be repeatedly used, and the seat cover is not damaged. Further, if wrinkles are found after the setting, wrinkles can be easily removed by lifting the holding plate at a position near the wrinkles or where wrinkles are easily removed.
