Embodiment Construction

[0033] In the drawings, components with the same function are provided with the same reference signs.

[0034] in figure 1 with 2 An IMD (In-Mold Decoration) mold 2 of an injection molding device not shown in detail is shown in the open position or in the closed position. The plastic part is manufactured with the help of the IMD mold 2, and the visible surface of the plastic part is provided with a decorative paint layer. The coating of the lacquer layer is carried out by the in-mold decoration technique with the aid of a carrier film, and the lacquer layer is applied on the carrier film. The carrier film and the paint layer together form a stretchable film 4, which is placed in front of the mold half 6 of the mold 2 on the demolding side in the open position of the IMD mold 2. The film 4 in this preferred embodiment is an "endless film", that is, a rolled material, which is sequentially unrolled during a mass injection molding process. The film 4 is here guided through the mol...

Abstract

The invention relates to an IMD mold (2) for producing a foil-decorated plastic part comprising a half mold (6) facing the foil and a half mold (8) facing away from the foil, wherein the two half molds can be placed on each other with corresponding mold dividing surfaces (14a, 14b) so as to form a cavity (10), which is substantially closed off from the outside, therebetween. At least the mold dividing surface (14a) of the half mold (6) facing the foil is formed by an inner area (12a) surrounding the cavity (10) and an outer area (13a) in turn surrounding said inner area (12a), wherein said mold dividing surface (14a) in the outer area (13A) lies in an at least substantially flat or one-dimensionally curved mold dividing plane (F), and wherein said mold dividing surface (14a) in the inner area (12a) is or can be set back with respect to the mold dividing plane (F).

Description

Technical field [0001] The present invention relates to an IMD (in-mold decoration) mold for manufacturing plastic parts for film decoration, which includes: a half mold facing the film and a half mold facing away from the film, wherein the two half molds can be Corresponding mold separation surfaces abut against each other, so that an externally closed cavity is formed between the two half molds. Such IMD molds are disclosed, for example, in DE 10 2007 007 409 A1. In addition, the present invention relates to an injection molding device having such an IMD mold, and to a method for manufacturing a film-decorated plastic part by means of such an injection molding device. Background technique [0002] Film-decorated plastic parts are usually manufactured as injection molded parts, which are provided with a decorative paint layer, wherein the latter may have a relief-like surface structure. The coating of the lacquer layer is carried out, for example, by the so-called In-Mold-Deco...
