Definitions
- connection element for media lines and injection molding device for producing the connection element
- connection elements produced as injection molded parts, although the transition channel section - viewed in a longitudinal section of the inner channel sections - be beveled or rounded in its outer angle region in the flow direction, but disadvantageously because of the opposite in the inner angle region edge contour of the remaining flow cross-section is narrowed. This results in an increased flow resistance.
- the present invention is based on the object to provide a connection element of the type mentioned, on the one hand has flow-optimized properties, on the other hand, however, continue to produce economically in an injection process as a substantially one-piece injection molding.
- the transition channel section has at least partially expanded in such a way relative to the inner cross section of the cylindrical inner channel sections Internal cross-section, that in this way are formed cross-sectional zones for receiving expected flow separation of a flow medium.
- these expanded cross-sectional zones are arranged and shaped in such a way depending on an expected media flow and resulting flow separation that, despite occurring flow separation, a remaining effective flow cross-section over the course of the transition channel portion is largely constant in terms of size and / or shape and preferably substantially the inner cross section the adjacent inner channel sections corresponds.
- the connecting element according to the invention can also have as a multiple element at least three inner channel sections, for example in the form of a T-connector.
- two inner channel sections straight line (coaxially) merge into each other, and the third inner channel portion may transversely, for. B. perpendicular, open to it.
- the inner angle regions of the transition channel section which respectively result in the transitional region between any two adjacent inner channel sections are then bevelled in the flow direction or are rounded in a convex manner.
- 9a and 9b are each a partially cutaway perspective view of
- Fig. 8 to 10 third embodiment of the device according to the invention leads to a two-stage production.
- the mold is designed as a two-stage tool.
- a three-part mandrel assembly 14a is provided with two cylindrical longitudinal core portions 50 and 52 for the cylindrical inner channel sections 4, 5 and with a corner core portion 54 for the transition channel section 8 functioning as a transverse core portion 16.
- the corner core part 54 forms from the outer angle region 10, leaving an opening 55 in the outer angle region 10, the side regions of the transition channel section 8 and also the inner angle region 12.
- the parts or sections corresponding to the first embodiment are initially provided with the same reference numerals, so that reference may be made to the preceding description.
- the angle ⁇ may well deviate from the right angle in the preferred range between 30 ° and 120 °.
- the transition channel section 8 has a region having such an inner cross-section widened in relation to the inner cross-section of the cylindrical inner channel sections 4, 5 that expanded cross-sectional zones 72 are formed.
- the expanded cross-sectional zones 72 can be arranged and shaped in such a way depending on an expected media flow and resulting flow separation that, despite occurring flow separation, a remaining effective flow cross-section over the course of the transition channel section 8 with respect to size and / or shape is preferably substantially constant, and in particular Substantially corresponds to the inner cross section of the adjacent inner channel sections 4, 5.
