摘要： The invention relates to a transfer system for a plastic injection device for manufacturing multi- component plastic workpieces. The invention is based on the object of creating solutions through which it becomes possible during the manufacture of multi-component plastic components, more preferably toothbrushes, to achieve advantages compared with previous manufacturing techniques. According to the invention, this object is solved through a transfer system for a plastic injection device with a mold, which can be opened via a mold separating surface which preferentially is substantially orientated vertically, a first injection station formed in the mold, a second injection station formed in the mold, a plurality of mold bars compatible both with the first injection station and also with the second injection station, each of which can be inserted in the first injection station and in the second injection station in the region of the mold chamber separating surfaces, wherein within the scope of a first injection step, pre-molded parts are manufactured in the first injection station which following the opening of the mold initially remain on the corresponding mold bar, the mold bar is embodied in such a manner that said mold bar can be brought into the second injection station jointly with the adhering pre-molded parts for injecting a second workpiece section onto the pre-molded parts in the second injection station, and that a transfer system is provided which is embodied in such a manner that through said transfer system a mold bar loaded with pre-molded parts within the scope of an injection step accomplished via the first injection station can initially be brought into an intermediate region which is located outside the mold and instead of the pre-molded parts just manufactured a mold bar provided with pre-molded parts within the scope of an earlier injection step preceding the mentioned injection step is brought into the second injection station.

摘要： A method for producing a brush head section for an oral care device has the following steps: injecting a first thermoplastic material into an insert-forming mold cavity to form an insert; transferring said insert into an over-molding mold cavity, wherein the insert is arranged partially inside and partially outside of said over-molding mold cavity; arranging one end of at least one cleaning element in said over-molding mold cavity, wherein the at least one cleaning element is arranged partially inside and partially outside of said over-molding mold cavity; injecting a second thermoplastic material into said over-molding mold cavity so that the part of the insert and the part of the at least one cleaning element which are located inside said over-molding mold cavity are over-molded by the second thermoplastic material, which second thermoplastic material thereby forms a cleaning element carrier, wherein the cleaning element carrier at least partly engages behind the insert and wherein the hardness of the second thermoplastic material is smaller than the hardness of the first thermoplastic material; and ejecting the resulting brush head section from said over-molding mold cavity.
