A molding apparatus includes an upper mold tool having an upper-most mold half, a lower mold tool having a lowermost mold half, and an intermediate mold tool having a first auxiliary mold half cooperating with the uppermost mold half and a second auxiliary mold half cooperating with the lowermost mold half. In a first molding step, the intermediate mold tool is positioned between the upper and lower mold tools to form a first mold cavity between the upper and intermediate mold tools and a second mold cavity between the intermediate and lower mold tools. In this molding step upper and lower material layers are individually pre-molded in the two cavities. In a second molding step, the intermediate mold tool is moved laterally away, and the upper and lower mold tools are moved directly into molding cooperation with each other. Thereby, the separately pre-molded upper and lower material layers are brought together, laminated, bonded, and molded to produce a finished, two-layered molded component.

An improved method and apparatus for laminating a cover sheet onto a substrate, and folding and laminating the cover sheet edges around the back side of the substrate rim are especially suited to making finished trim panels having a strongly contoured three-dimensional configuration. A carrier frame holds the cover sheet material with a desired tension until the lamination has begun, to avoid wrinkling and sagging of the cover sheet material on a strongly contoured three-dimensional substrate. A lower mold receives the substrate, while an upper mold laminates the cover sheet onto the substrate. The upper mold can be retracted into or extended from a frame that forms a nest, while edge-folding tools are laterally movably arranged around the perimeter of the upper mold nest. The lamination and molding is initiated with the upper mold extended beyond or below the plane of the edge-folding tools and the cover sheet still held by the carrier frame, and then the two molds together are retracted above the plane of the edge-folding tools to begin the edge-folding step.

An apparatus for forming trim panels has upper and lower mold sections which perform a laminating and bonding between a substrate and a cover sheet while simultaneously cooperating with one or more folding devices to fold a sheet edge around a substrate rim to bond the sheet edge to the back of the substrate rim. Where prelaminated sheets are used, a brim is formed of the sheet edge and a substrate rim and the brim is first folded, after heating, through an angle of 90.degree. and then through a further angle of 90.degree. to complete the fold.

An apparatus for producing a molded product from a sheet-form raw material blank has first and second mold tools that each respectively include a respective inner core mold and a respective outer edge mold laterally adjacent thereto. Drive elements drive the outer edge molds relative to a machine frame, and drive the inner core molds relative to the outer edge molds. A molding process involves closing the outer edge molds to hold an edge rim of the material blank while allowing slippage thereof, and then closing the inner core molds to three-dimensionally deform and mold a central portion of the material blank while pulling required additional material by slippage through the outer edge molds. A separate slip frame is not used. The edge rim held by the outer edge molds remains as a permanent mounting rim or flange of the finished molded product. Edge waste is minimized.

An apparatus includes a heating station, a laminating and transfer-printing station, and a molding station in succession, and a transport arrangement that transports the material being processed among the stations. In the heating station, a substrate is pre-heated and consolidated. In the laminating and transfer-printing station, a decorative cover layer is laminated onto the substrate and simultaneously a surface decoration (design, pattern, image, colors, text, etc.) is transfer-printed by sublimation of inks or dyes from a transfer paper onto an outer surface of the decorative cover layer. The resulting laminated body with a transfer-printed surface decoration is then three-dimensionally deformed and molded to form a three-dimensionally contoured, molded, laminated article with the transfer-printed surface decoration. The article may be a motor vehicle interior trim component.
摘要:
A trim component includes a foam backing layer and a foam pad insert laminated between a cover material and a substrate. The foam pad insert provides an area of enhanced cushioning, and has smoothly tapered edges to ensure a smooth surface contour without a visible edge transition on the cover material. The foam pad insert has a lower melting temperature than the foam backing layer, both of which are thermoplastics. A foam pad insert is positioned and fixed on the back surface of the foam backing layer. A substrate material is heated and then laminated and molded with the foam and the cover material. The heat from the substrate partially softens and melts the foam backing layer and the foam pad insert. The partially melted foam pad insert is viscously deformed to form the tapered edges, as dictated by the smoothly varying mold gap spacing of the forming tools.
