Embodiment Construction

[0050] In the various figures of the drawings, identical parts are always provided with the same reference numerals and are therefore generally only described once. With regard to the following description, it is hereby claimed that the invention is not limited to the described embodiments and in this case not to all or more features of the described feature combinations, but rather to each individual partial feature of the described embodiments It is also separate from all other partial features described in connection therewith and also combined with other features essential to the subject-matter of the invention.

[0051] as in Figures 1a to 1c and Figures 2a to 2c As shown, the invention relates to a plug connector 1 which is designed as a molded part 1a of plastic, produced by injection molding and has an inner channel 2 for the fluid and an at least partially annular cross-section Q. The different sectional views through the cross-section are shown in 4a to 4g, which...

Abstract

The invention relates to a plug connector (1) designed as a plastic part (1a) produced by injection moulding, with an internal channel (2) for a fluid, an at least partially annular transverse Section (Q) and three main sections (A1, A2, A3) arranged one behind the other in the axial direction. In order to provide such a plug connector (1) which can be manufactured in an improved manner in terms of material economy and productivity while maintaining the required axial straightness (ΔX), it is proposed that the The molded part (1a) has injection points (9) on its outer circumference only on one side, wherein at least one of the main sections (A1, A2, A3) of the molded part (1a) There is a radially asymmetric material distribution of the plastic along the circumference. To this end, according to the same proposed method, a filling control is arranged in at least one of the regions (B1, B2, B3) of the axial length (L) of the inner wall (14) of the mold (5) used for production. An element (16) which prevents the flow of the polymer mass (M) used as plastic material in the axial direction (X-X) and / or produces an asymmetrical distribution.

Description

technical field [0001] The invention relates to a plug-in connector, which is designed as an injection-molded part made of plastic and has an at least partially annular cross-section and an inner channel for the fluid and three main sections arranged axially behind each other , namely the middle section and two connecting sections adjoining the middle section on both sides. [0002] Furthermore, the invention relates to a method for producing such a plug connector, wherein the plug connector is produced as a molded part from plasticized plastic as a polymer material by injection molding Injected under pressure radially inwards into a cavity formed by the inner wall of the mold, wherein a core is arranged in the cavity for forming the inner channel of the plug-in connector, around which core the polymer material is circumferentially Flow upwards and in the axial direction until the cavity is completely filled, after which the polymer mass is cooled, if necessary under applied ...
