Disclosed herein, amongst other things, is, a stripper assembly operable to eject a molded article from a mold that includes slides that are movable laterally relative to each, a first split mold insert inter-connected to a first slide and a second split mold insert inter-connected to a second slide. The system being operable such that when the first and second slides are in the closed position, the first and second split mold inserts form at least a portion of the molding cavity; the system being operable such that such during operation of the injection molding system, the first split mold insert is movable relative to the respective first slide and the second split mold insert being movable relative to the second slide.

A medical silica gel stethoscope, including a sound conducting pipe, the sound conducting pipe includes a U-section and a straight pipe section, said U-section and straight pipe section are molded integrally, and its manufacturing method thereof. The present invention also relates to a processing mold for said medical silica gel stethoscope. Technical effects of the present invention: 1) the U-section and straight pipe section of medical silica gel stethoscope of the present invention are molded integrally, so the inner wall of the pipe is free of seams, the sound conduction effect is better. The molding of the traditional splicing molded medical silica gel stethoscope requires at least three molds, whereas the one-step molded structure of the medical silica gel stethoscope of the present invention is easier for processing.

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.
