Join device and join a method of materials and the scarfskin for interior wallcovering of automobiles

摘要

The present invention relates to a joining device and a method of joining a substrate for the interior material of the automobile and the skin material, in the past, most of the interior material products that partially adhere the skin material to the surface of the base material or adhere with a two-tone color produced by hand This is because the adhesive area is not smooth and the quality is lowered and the productivity is lowered.;Therefore, the present invention provides a lower mold 20 having a concave portion 22 formed on a molding surface for forming a rib 31 having a predetermined thickness into a bottom surface of the substrate 30 to be injection molded; A pair of first upper mold 10a and a second upper mold 10b separated from each other by the position of the recess 22 in the lower mold 20; In the forming surface between the first and second upper mold (10a) (10b) is variably protruded by the cylinder 70 to form a rim insert groove 32 of the skin material on the rib 31, the skin material Insert rod 60 for inserting into the insertion groove 32; As the cylinder 70 itself for elevating the insert rod 60 and the cylinder 80 for elevating the first upper mold 10a separately from the second upper mold 10b, the present invention is a substrate 30 When the skin material is adhered by using the residual heat of the skin material is well bonded to the substrate 30 by partial adhesion or two-tone color, so the work process is quick and simple, the productivity is improved, and the appearance is beautiful.
