Abstract: An injection moulding device for producing an injection moulding has a first (16a, 16b) and a second (14) mould plate which can be moved relative to each other in the closing direction. Furthermore, the injection moulding device comprises a mechanism (17a, 17b) for repositioning at least one (16a, 16b) of the mould plates in such a way that at least two different de-moulding directions (R1, R2) in relation to the injection moulding can be implemented.

Abstract: An injection molding machine is proposed, especially for injection stamping of large-area plastic moldings, comprising at least a first injection mold (13) which has two mold halves (15, 16) and which forms a first cavity (17) with a first projected area, and a second injection mold (14) which has two mold halves (18, 19) and which forms a second cavity (20) with a second projected area, one mold half (15, 18) of the two injection molds (13, 14) respectively being fixed on a common carrier unit (21) and for the two injection molds (13, 14) there being support means (22A to 25A; 22B to 25B) acting in the opening direction. In order to limit the force acting on the respective cavity, the support means (22A to 25A; 22B to 25B) depending on the respective projected area of the respective cavity (17, 20) partially take up the clamping force so that a holding pressure force acting on the material which has been injected into the respective cavity (17, 20) is set.

Abstract: A molded plastic part comprises a plastic part and a plastic component molded onto the plastic part. The plastic part has a portion at the border which is insert-molded by the polymer melt of the molded-on plastic component.

Abstract: In a process for molding a plastic component onto a prefabricated plastic part, a first mold plate (1) and a second mold plate (105) are closed, a cavity in which the prefabricated plastic part (101) is located being formed between the closed mold plates (1, 105). One of the mold plates (105) is formed with a depressed zone (108) and a polymer feed (115) opening out into the depressed zone (108) for molding the plastic component onto a region of the prefabricated plastic part (101) that lies opposite the depressed zone (108). Subsequently, polymer melt is injected into the depressed zone (108) and, during the injection of polymer into the depressed zone (108), the mold plates (1, 105) are moved apart.
