Abstract: 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).

Abstract: The present invention concerns a transfer element (1, 9) for an injection molding system comprising a flow lumen for a plasticised plastic material. To provide a transfer element for an injection molding system, which makes it possible to further increase the material throughput of the injection molding system without having to tolerate increased wear of seals and other system components, it is proposed in accordance with the invention that it has a device for degassing of the flow lumen.
