Abstract

PURPOSE:To cover and integrate various kinds of skin materials on the surface of a plastic molded product properly and easily without generating creases and breaks by pressing a supporting agent of the material to a bottom force by means of a pressing frame while leaving a preformed laminate skin material in the bottom force, mold registering a top force correspondingly to the bottom force and injecting a plastic material from the bottom force side to a cavity section between the top and bottom forces. CONSTITUTION:A laminate skin material 11 constituted of a skin material over which an extensible plastic film of a little larger than the skin material is laminated is used, and its laminate section is preformed into the required shape. A supporting edge 14 on the periphery of the material is pressed to a bottom force by means of a pressing frame 5 while the preformed laminate skin material is left in the bottom force 1 and a top force 4 is mold registered, and a foam synthetic resin raw material is injection foamed from the bottom force side to a cavity section 8. Thus, a preformed laminate section is brought into contact with the inner surface of cavity section while the supporting section on the periphery is stretched, and a plastic molded product is formed without creases and breakage and simultaneously is covered and integrated on the surface of the material.

(Prior art) The conventional manufacturing method for this type of plastic molded product with a skin material is to set a sheet-like skin material between the upper mold and the lower mold, which are to be matched, and to insert the raw material inlet provided in the lower mold. It is common practice to inject foamed plastic raw materials and mold the skin material to the cavity surface using the injection pressure and foaming pressure, but when using this method, unless the skin material is extremely flexible, Since it is difficult to adhere to the cavity surface, wrinkles and tears are likely to occur, and the types of skin materials are limited. Therefore, attempts have been made to eliminate the above drawbacks by preforming the skin material using a preform mold prepared separately, but this complicates the process and requires a special clamping mechanism. Therefore, it cannot be mass-produced at low cost.

On the other hand, (11) is a laminated skin material, and the laminated skin material (11) is made of plastic by laminating the main skin material (12) and a two-wheel stretched type plastic film (13) that is slightly larger than the main skin material (12). The part of the film (13) that protrudes from the periphery of the skin material (12) is formed into a support edge (14) that can be stretched. Then, this laminate skin material (1
1) is clamped and set above the lower mold (1) by a well-known clamping mechanism (7) as shown in FIG.
is lowered to preform the laminated portion (15) of the laminate skin material (11), excluding the supporting edge (14), into a desired shape. In this way, the laminate skin material (1
When the preform in step 1) is completed, the upper preform mold (3) is raised and the presser frame mold (5) is lowered to remove the support edge (14) of the laminate skin material (11) as shown in FIG. As shown in FIGS. 4 and 5, the presser frame mold (5) is pressed against the lower mold (1) and moved below the upper mold (4) for main molding, and then the upper mold (4) As shown in Figures 4 and 5, if the mold is matched to the lower mold (1) and the foamed plastic raw material is injected from the raw material injection port (2), the injection pressure and the foaming pressure will create a gap between the upper and lower molds. The cavity part to be formed (
8), the foamed plastic raw material is the preformed laminated part (1) of the laminated skin material (11).
5) a support edge (14) with excellent stretchability on its periphery;
The foamed plastic raw material injected in this state is molded into a plastic molded product (21), and at the same time the laminated portion (15) of the laminated skin material (11) is formed on the surface. Since the adhesive is integrated, all you have to do is open the mold, remove it, and then cut out the supporting edge (14) along with the unnecessary part (22) of the plastic molded product. If the inner diameter of the cavity of the upper die (4) for main molding is made slightly larger than the inner diameter of the presser frame die (5), the skin material will be rolled up to the terminal part for a good appearance, as shown in Figure 6. Becomes a product.

(Effects of the Invention) As is clear from the above description, the present invention uses a laminated skin material in which a slightly larger extensible plastic film is laminated to the skin material, and preforms the laminated portion into a desired shape. Then, leaving this preformed laminated skin material on the lower mold, press only the supporting edge of its periphery against the lower mold with a presser frame mold, align the upper mold, and apply foamed synthetic resin from the lower mold side. By injecting and foaming the raw material into the cavity, the preformed laminated part under the stretching of the supporting edge around the periphery is brought into close contact with the inner surface of the cavity, thereby preventing the plastic molded product from wrinkling or breaking. It can be integrated into the surface at the same time as molding, and it does not matter what kind of skin material is used, even if it has poor stretchability or is breathable, and the process is simple or complex, and a ramp mechanism is also required. Coupled with the advantage of being able to reduce costs because the plastic molded product does not have to be exposed, the present invention greatly contributes to the development of the industry as it solves the problems of the conventional manufacturing method of plastic molded products with a skin material. .
