An injection-compression molding device (1), wherein the rod (3) and the core (5) are connected to each other by means of a joint (20) which allows to have a rigid connection in some steps of an injection-compression molding process, and an articulated connection during the compression step of the injection-compression molding process.

Provided are a device and method for molding an FPC and a plastic part, which belongs to the field of FPC processing technology. The method for molding an FPC and a plastic part includes preprocessing a preform and connecting an FPC to the outer cylindrical surface of the preform; and forming a coating on the outer cylindrical surface of the preform by using the device for molding an FPC and a plastic part.

This molding method involves: a first step in which a perforation pin (2) is made to protrude into a cavity (13) in a mold (1); a second step in which a molten resin (16) is injected to fill the cavity (13) so as to envelop the protruding part of the perforation pin (2); a third step in which, in a state in which the resin (16) is in an uncured state, the perforation pin (2) is made to protrude further; and a fourth step in which the resin (16) is cured to obtain a molded resin article.

The present invention concerns a multi-part core insert (1) for an injection molding mold (100) for the production of preforms having a two-part core having a longitudinal axis (10), wherein the two-part core has a lower core part (20) and an upper core part (30) arranged beside the lower core part (20) in the direction of the longitudinal axis, and a fixing element (40), wherein the fixing element (40) has an opening parallel to the longitudinal axis (10) for receiving the upper core part (30), and wherein the upper core part (30) can be fixed with the fixing element (40) at an end (22) of the lower core part (20). To provide a core insert for an injection molding mold, whose shaping portion can be easily and quickly exchanged, while at the same time ensuring the quality and functionality of the injection molding procedure, it is proposed according to the invention that the fixing element (40) and the upper core part (30) are of such a configuration that when the upper core part (30) is received in the opening a positively locking and/or force-locking connection can be produced at least in the axial direction between the upper core part (30) received in the fixing element (40) and the fixing element (40), and the fixing element (40) and the lower core part (30) are of such a configuration that the fixing element (40) can be fixed to the lower core part only in one position or in a plurality of positions which differ by rotation of the fixing element (40) relative to the lower core part (20) about the longitudinal axis (10), wherein only a finite number of positions, preferably a maximum of four positions, of the fixing element (40) relative to the lower core part (20) are possible.

The invention relates to an injection mold for manufacturing an injection-molded component from plastic material. The injection mold including an outer first half-mold and an outer second half-mold, which, when joined, define an empty space, which determines an outer contour of the injection-molded component, and a core, which is located in the empty space and determines an inner contour of the injection-molded component. A wire passes through the core and the joined outer first half-mold and outer second half-mold, and plural pairs of clamping jaws fix the wire in its position. A method for manufacturing an injection-molded component is also disclosed.
