    Trimming and press forming apparatus and method of automobile interior materials
    The present invention relates to a method of molding automotive interior parts using wool / paper and a PP board. The present invention is a trunk mat that is mounted on the floor of the trunk as a part of automobile interior parts, and serves as a fixture for a spare tire cover and a jack and blocks noise of the trunk. Trimming and press forming apparatus for producing trunk mat cover'g (so-called luggage mat cover'g), trunk trim or trunk lid, etc .; and It is about a method.
    In the conventional case, each of the trimming device and the shaping device, such as trunk mat covering, is as shown in FIG. Molding wool / paper trimming iron mold (3) for trimming wool / paper (1), board trimming iron mold (4) for trimming PP board (2), trimmed wool / paper and PP board Molding molds 5 for processing were each present separately. In addition, referring to the conventional molding method, as shown in Figure 2, the product was produced in a total three-step process. As shown in FIGS. 2A and 2B, the wool / paper 1 and the PP board 2 are different from each other of the wool / paper trimming iron mold 3 and the board trimming iron mold 4, respectively. ) Is trimmed and pierced. Thereafter, a molding process is performed in the molding die 5 as shown in Fig. 2C. At this time, the PP board 2 is subjected to the preheating process in the oven (oven) on the characteristics of the material and then continues to the process of Figure 2c.
    That is, the conventional trimming device and the molding device are separately installed, and the conventional molding method is a three step multi-step process as described above.
    Therefore, the molding process is complicated and takes a lot of time, there was a problem that the work force is wasted. When working in a single process of Figure 2 there is a product deformation due to shrinkage during operation in the state of Figure 2c, there was a problem that the deterioration factor occurs.
    Accordingly, an object of the present invention for solving the above problems is to provide a trimming and press forming apparatus and method for automotive interior materials that can shorten the operation method of the multi-step process in a single process in the trimming and press molding of automotive interior materials. .

    In order to achieve the above object, a trimming and press forming apparatus for molding an automobile interior, in particular trunk mat covering, trunk lid, trunk trim, etc. according to the present invention with reference to Figure 3 will be described in detail.
    The trimming and press forming apparatus of the automotive interior of the present invention, the upper cutter 10 is installed on the upper side for trimming and piercing the upper material (1) and the preheated lower material (2) Jig 7 equipped with cutter A for trimming and piercing to desired size, upper pad 9 provided on the upper side for press molding upper and lower materials 1 and 2, and preheated lower material A lower cooling tank 6 for placing the upper and lower materials 1 and 2 together with the upper pad 9 and cooling the preheated lower material 2 with the upper pad 9 placed thereon; After the press operation, a stripper 8 for separating scrap from the lower cutter, a plurality of strips 8 for moving the upper pad 9, the jig 7 and the stripper 8 on which the cutter A is mounted by respective stroke distances. By including springs (11, 12, 13), and trimming the automotive interior material Press molding can be carried out at the time.
    The upper material 1 is wool / paper, and the lower material 2 is a PP board.
    As shown in FIG. 3, the jig 7 with the cutter A mounted on the lower left side of the jig 7 to trim the outer portion of the PP board 2 when the upper pad 9 and the upper cutter 10 are lowered. The cutter is configured to be formed, and is installed above the lower cooling tank 6 so as to trim the PP board 2 placed on the lower cooling tank 6. As shown in FIG. 4A, the jig 7 having the cutter A mounted thereon is provided with the cutter A installed in the lower end of the jig 7, or as shown in FIG. 4B. The cutter A is installed in the lower end portion, or as shown in FIG. 4C, the cutter A is installed to protrude in an arc shape in the lower portion of the lower end portion. The upper cutter 10 is configured such that cutters are formed at lower ends of both sides in order to trim the outer edge of the wool / paper 1.
    In FIG. 3, for convenience of explanation, the jig 7 and the lower cooling tank 6 on which the upper mold pad 9 and the cutter A are mounted are shown flat, but since they are formed in the shape of the product to be molded, the upper mold When the pad 9 and the upper cutter 10 are lowered, the wool / paper 1 and the PP board 2 are configured to press-mold to the desired shape while trimming the outer edge thereof.
    The trimming and forming method of the present invention is a method of trimming and pressing molding the wool / paper 1 and the PP board 2 preheated in an oven as shown in FIG. The molding method of the present invention is not a method of cutting the raw materials, transferring them to a molding die, and molding them, but a method of simultaneously trimming and molding the raw materials themselves.
    First, the preheated PP board 2 is fixed on the lower cooling tank 6 and the wool / paper 1 is fixed on the jig 7 on which the cutter A is mounted.
    Then, the setting of the material is completed, and then gradually lowering the upper mold, that is, the upper mold pad 9 and the upper cutter 10, causes the jig 7 with the cutter A to be mounted on the PP. The board 2 is partially cut to cut to desired dimensions. At the same time, the upper cutter 10 trims and pierces the wool / paper 1 and the PP board 2 together.
    At the same time, the upper mold pad 9 is also in close contact with the jig 7 equipped with the lower cooling tank 6 and the cutter A to press (press) the wool / paper 1 and the PP board 2. Molding.
    Then the material is finally removed from the mold to complete the process.
    Accordingly, the wool / paper 1 is placed on the jig 7 with the cutter A and the preheated PP board 2 is placed on the lower cooling tank 6 as described above. When the lower cutter spring 12 and the stripper spring 13 are operated to move by the stroke distance, the upper pad 9 and the upper cutter 10 are lowered, and thus the wool / paper 1 and the PP board ( 2) the upper part 10 is trimmed by the jig 7, on which the upper cutter 10 and the cutter A are mounted, and the desired position is pierced, and the upper pad 9 is connected to the lower cooling tank 6. By being in close contact with the jig 7 equipped with the cutter (A) is press-molded, it is possible to perform the trimming and the press-molding treatment simultaneously in a single process.
    In the above description, trimming and molding of the trunk mat covering has been described, but the present invention is not limited thereto, and may be used for trimming and shaping the spare wheel cover, the trunk trim, and the trunk lid.
    In addition, in the above description, a case in which wool / paper is used as the upper material 1 and a PP board is used as the lower material 2 is described. However, the present invention is not limited thereto and may be used in various materials. .
    As described above, by converting the working method of the conventional three-step process into a single process by converting the working method of the multi-process into a single process, the workability can be improved and the manpower accordingly Can be saved.
    In addition, the installation cost and manufacturing cost of the conventional three-step process can be reduced, as well as the overall product production time.
