Definitions
- the present invention relates to a line connector for media lines, in particular for pipe or hose lines for hydraulic flow media, consisting of a connector piece with at least one connection portion for connection to a media line or with an aggregate and with an adjacent to the connection portion transition portion with an inner flow channel.
- Such line connectors are used for mutually connecting at least two media lines or for connection connection of at least one line with any aggregate, in particular in a motor vehicle.
- such media are often routed through the lines that tend due to a relatively high freezing point even at relatively high, depending on the weather quite possible ambient temperatures to freeze. This can affect certain functions. This is the case, for example, with water pipes for the windscreen washer system as well as with lines for a urea solution, which is used as NO ⁇ reduction additive for diesel engines with so-called SCR catalysts.
- connection serving end portions of the connecting element can be aligned with respect to their longitudinal axis in a connector angle between 0 ° and 180 ° to each other.
- the inner channel can have a rounded inner contour, at least in the transition section between the end sections-seen in the longitudinal section of the inner channel-both in an outer angle area and in an inner angle area.
- the present invention relates to a device for producing a line connector of the aforementioned type or such a connection element, with an injection mold, which comprises a mold core arrangement for forming an inner channel of the connection element.
- connecting elements designed as angle connectors are known, which are each produced by injection molding in a molding tool. It is known that the tool has two one-piece mandrels in the form of simple longitudinal slides, which are pulled axially for removal from the respective end portions of the inner channel. To form the transition section, the mandrels have a corresponding shape at their mutually facing ends.
- Such tools are quite inexpensive, but have the disadvantage that in the interior angle of the angle connector inevitably creates a sharp-edged contour that causes in use by flow separation, turbulence, secondary and reverse flows and the like, in the flow medium and therefore disadvantageously leads to flow or pressure losses ,
- Response time is understood to be the technically conditioned time that elapses from the touch of the brake pedal until the start of the pressure increase in the system. It ends with the touch of contact of the brake pad on the brake disc or brake drum. During the response time, the vehicle is not yet braked.
- Threshold time of a brake system is understood instead the time that elapses from the beginning of the pressure increase until reaching the full brake pressure.
- the swelling time is regulated by the EC Regulation ECE R13 predefined; it is 0.2 to 0.4 seconds for trucks.
- the mentioned response and swelling times in a compressed air brake system are decisively influenced by the flow velocity of the air in the lines of the brake system. Since today's truck braking system can contain a fairly large number of such angle connectors (often 30 or even more), the flow losses of the individual angle connectors in the sum are particularly disadvantageous.
- the mandrel assembly consists of two axial, in the direction of the longitudinal axes of the end portions of the inner channel like a movably guided longitudinal core parts, wherein each longitudinal core part is divided in the longitudinal direction into two slide parts, namely - based on the connector angle - in an outer and an inner slide part.
- the inner slide parts are formed with their ends facing each other for forming an example convexly rounded inner angle range of the angle connector, which can be avoided with advantage in the inner angle range, the formation of sharp-edged contours.
- the inner channel thus has, at least in a transition section between the end sections-seen in the longitudinal section of the inner channel-a rounded inner contour both in an outer angle area and in an inner angle area.
- the outer slide parts are first pulled axially out of the connection element, whereupon the inner slide parts are then moved with their ends facing each other transversely to the longitudinal axis of the associated inner channel section away from the inner angle area and can then likewise be pulled out axially.
- This technical solution is advantageous in that it creates a flow-optimized angle connector which leads to a considerable reduction in the flow or pressure losses in the fluidic medium.
- this advantage is paid for by an increased constructive and technological effort by using multi-part core parts, which must be removed separately in successive operations.
- the present invention is based on the object to provide a line connector of the type mentioned above, which is characterized by a reduced production cost in flow-optimal design of its inner channel.
- This object also comprises the provision of a device of this type for the purpose of producing the line connector serving this purpose.
- this object is achieved for the line connector in that a line piece is embedded in the transition section, which forms at least part of the wall of the inner flow channel.
- the mold core assembly has a circular arc-shaped curved core which is pivotable for demolding of the molded conduit connector in a Entformungshchtung about the center of a circle describing the curvature of the core.
- the line piece which may have a preformed flow-optimized inner cross-section, can be inserted in a simple manufacturing technology before injection molding in an injection mold.
- An important advantage associated with the invention consists in the fact that by the insertion of the line piece into the cavity of the injection mold in the formation of the inner channel a support by cores can be completely or at least partially avoided, without causing a sharp-edged contour which could later cause pressure losses due to flow separation, turbulence, secondary and backflow, etc. in the flow medium.
- the inventive device can be done by the inventive device, if necessary, an effective inner support of the pipe section in an injection molding, without thereby creating an increased technological effort.
- the invention can be used advantageously for simple angle connectors, but in particular also for connecting a, the line connector forming angle plug to a pipe.
- the tube does not need by a so-called thorns, d. H. a positive and non-positive fitting of the pipe to a plug pin to be connected to the plug, but can also be cohesively, for example, by injection or by laser technology, and optionally also positively secured, creating a risk of leakage is excluded.
