Embodiment Construction

[0033] Components having the same effect in the figures are provided with the same reference symbols.

[0034] exist figure 1 and 2 An IMD (in-mold decoration) mold 2 of an injection molding device, not shown in detail, is shown in an open position or in a closed position. The plastic part is produced by means of the IMD tool 2 , the visible side of which is provided with a decorative lacquer layer. The application of the lacquer layer takes place by means of in-mold decoration technology with the aid of a carrier film onto which the lacquer layer is applied. Together with the lacquer layer, the carrier film forms an extensible film 4 which, in the open position of the IMD tool 2 , is placed in front of the mold half 6 of the tool 2 on the release side. The film 4 in this preferred embodiment is an "endless film", ie a roll material which is successively unrolled in a mass injection molding process. The film 4 is guided through the mold 2 by means of a conveying device, no...

Abstract

An IMD mold for producing a foil-decorated plastic part contains a half mold facing the foil and a half mold facing away from the foil. The two half molds can be placed on each other with corresponding mold dividing surfaces so as to form a cavity, which is substantially closed off from the outside, therebetween. At least the mold dividing surface of the half mold facing the foil is formed by an inner area surrounding the cavity and an outer area in turn surrounding the inner area. The mold dividing surface in the outer area lies in an at least substantially flat or one-dimensionally curved mold dividing plane, and the mold dividing surface in the inner area is or can be set back with respect to the mold dividing plane.

Description

technical field [0001] The present invention relates to an IMD (In-Mold Decoration) mold for the manufacture of film-decorated plastic parts, comprising: a mold half facing the film and a mold half facing away from the film, wherein the two mold halves can be Corresponding mold parting surfaces rest against each other, so that an externally closed cavity is formed between the two mold halves. Such an IMD tool is disclosed, for example, in DE 10 2007 007 409 A1. Furthermore, the invention relates to an injection molding device having such an IMD tool and to a method for producing a film-decorated plastic part by means of such an injection molding device. Background technique [0002] Film-decorated plastic parts are usually produced as injection-molded parts which are provided with a decorative varnish layer, the latter possibly having a relief-like surface structure. The application of the lacquer layer takes place, for example, by the so-called In-Mold Decoration (IMD) te...
