Description

The invention relates to a housing body for mechatronic flow measuring devices and mechatronic lifting body flow measuring devices with such housing bodies according to the independent claims. From the WO 2009080352 A1 a generic mechatronic flow measuring device with a cuboid housing body is known in which the position of a fluid-tightly attached to the housing body, fluid deflectable lifting body can be detected with a transducer. Mechatronic flowmeters are manufactured and sold by the applicant under the name SBY and SBU. Such measuring devices can be used for medium or fluid temperatures up to about 80-120 ° C and are therefore not or only slightly for high temperature applications (about 80-120 ° C, especially about 200 ° C) suitable. Such temperatures occur, inter alia, when tempering injection-molded tools. Also known thermoforming process, thermoforming plants and injection molds with fluid-heated / fluid-cooled tempering, which have multiple flow meters, wherein the flow meters z. T. high temperature resistance requirements are due to the high processing temperature of the injection molding itself and / or by a high mold temperature. An injection molding or injection molding tool is a tool consisting of several assemblies and various items, mainly steel, which is used to produce large numbers of plastic parts. An injection molding tool can have one or two parting planes and multiple cavities with mandrels per parting plane, ie, several plastic parts can be produced simultaneously in one mold. Tools with two parting planes often have a two-sided helical screw drive, which allows fast, parallel opening and closing of the two forming planes. Further basic components of injection molding tools are: a) clamping plates for clamping the tool onto the injection molding machine b) sprue c) cooling circuit d) evaluation unit. The plastic is injected by means of the cylinder of the injection molding machine at high pressure through the feed channels in the cavities of the tool, so that the air escapes. By means of special ventilation channels in the molded part is cooled down as far as a cooling circuit until it can be "demolded". The duration of a cycle (time between two demouldings) depends on the workpiece size and the cooling time. The demoulding is done by so-called ejector, which can be used to remove the molds removal robots. The service life of the injection mold depends on various parameters of the injection cycle, such as temperature and temperature differences or the injection pressure. One differentiates among other things between cold runner and hot runner tools. In cold runner systems, the plastic cures in the sprue and is separated after ejection of the molded part. Hot runner systems may have so-called needle closure systems, in which the injection nozzle is closed by a valve needle directly after the pressing. Further types of injection molds are: a) three-platen tool b) insulating channel tool c) stack mold. As a molding tool called machining tools and hand tools are used in the main groups of forming manufacturing processes, prototypes and forming, in machine tools or in the craft. Most relevant is the DIN 8580 or newer demensprechende standards. Forming tools occupy a central position in many areas of the manufacturing and processing industry. They are particularly important in the metal industry, especially in the sheet metal processing industry (eg car body construction) and in the entire casting industry, in plastics processing (especially in injection molding) and in some areas of the craft industry (eg Forge). The manufacture of measuring device housings or food packaging, such as cups, lids and bowls made of plastic, places the highest demands on the precision of the injection molding and thermoforming tools, in particular on the cycle time and cycle point-exact fluid temperatures of the supply and / or return or the individual Fluid channels of thermoforming or injection molding. Thermoforming is a process for forming thermoplastics. It used to be called thermoforming, deep drawing or vacuum forming. A distinction is made between the thermoforming processes according to the semi-finished product: Thinner semi-finished products are called foils, thicker (from approx. 1.5 mm) plates. Film semi-finished products can be fed to the thermoforming machines on large (up to m 1.8 m) rolls. In addition, thermoforming is the tool for thermoforming. When vacuum thermoforming z. B. the following steps or procedural actions usual and typical: 1) insert film 2) clamping frame to 3) heating 4) pre-blowing 5) mold helpers off; Table up / down 6) Vacuum on 7) Cooling 8) Demoulding 9) Open machine; The cycle times are about 30 seconds to 10 minutes, so they are much longer than injection molding machines (often less than 3-5 seconds!). Depending on the plastic or starting material, the tools must be cooled or heated, if necessary, a preheating station is required. Forming tools with optimal cooling, heating and temperature control, above all an automated temperature control, as well as an efficient quick-change technology are the basic requirements for high-quality products and a low reject rate. POM molding compounds can be processed on all conventional injection molding machines with conventional universal screws. Sprues, gates and Hot runner systems should not be too small. POM molding compounds can or must be processed by injection molding at melt temperatures between 180 ° C to 230 ° C and can be demolded well. At higher temperatures, which is desired for more productivity, a (very) short residence time should be taken care of since the material can be thermally damaged. The tool temperature for optimum strength, rigidity and hardness should be between 60 ° C and 90 ° C. To reduce the shrinkage, the temperature can be raised to 120 ° C or more. A possible partial distortion can be counteracted by different temperature of the mold halves. A well-designed fast and precise tempering influences the surface quality, shrinkage and tolerances of the moldings via the tool, fluid and molding compound temperatures. Providing precise recommendations for the molding materials or starting materials is difficult because they depend inter alia on the tool design, the mold temperature control and the injection molding machine used and can be given only after knowledge of all boundary conditions. Therefore, it is very important to be able to carry out the tool, fluid and molding material temperature control precisely and precisely in terms of time. Injection molds must be tempered zone dependent depending on the process. Depending on the tool size, one or more temperature control circuits are required. The flow rate must be separately adjustable for each temperature control circuit to ensure the required temperature range for the respective zone in the injection mold. A well-known from practice simple way of Temperiermedienverteilung is the distribution of so-called blind distributors. In this system, the Temperierfluidverteilung is realized by individual outlets from a central tube. The individual outlets can be shut off, an indication of the Temperierfluiddurchflusses per single channel is usually omitted. Blind distributors have the disadvantage that a regulation and visualization of the Temperiermedienströme is not possible. If the Temperiermediendurchfluss disturbed in one or more zones of the injection mold, so errors can be detected only on hand quality defects on the molded parts produced. From the DE 41 15 963 A1 It is known to use for cooling of injection molds with multiple cooling circuits, which are acted upon with different flow rates per unit time, for each circuit in each case a variable area flow meter, which are arranged in the form of a register immediately adjacent to each other in series. The inflows and outflows of all circuits are combined via collection channels. For this purpose, transverse channels are arranged between the individual measuring devices for the common outflow or return flow in the upper flow fitting and, in an analogous manner, transverse channels in the lower flow fitting, for the inflow or flow. The flow rates for the individual circuits are manually adjustable by means of control valves, whereby the respective flow rate for a cycle can be read off and controlled via the defined buoyancy of a float in a transparent sight glass. Such systems have the disadvantage that they do not meet all the requirements for electronic precise and rapid process monitoring and process control, especially with regard to accurate, fast flow velocity and / or flow quantity detection including fluid temperature control. The set flow rates are unstable depending on the applied central temperature control medium and on the pressure conditions in the system tool temperature control circuit and can not be influenced automatically. The reading of flow values at the sight glass is essentially dependent on the existing tempering medium quality, a practice-usual chemical treatment of the tempering medium leads to contamination of the sight glasses, which makes it difficult to control the flow rate. For computer-controlled temperature control and process monitoring, the electronic acquisition of process-relevant data as well as the control of electrical control elements is an essential procedural basis. These measuring and control units must currently be additionally integrated into the separate cooling circuits, which is associated with additional effort. The inevitably existing mechanically operated control valves and flow-through sight glasses remain unused for automatic, temperature-regulating process control and cause additional costs. For example, the production process for plastic-based data media is set so that a sufficiently accurate substrate quality is achieved with the shortest possible cycle time. Since a good impression quality of the information structure of optical data carriers requires a high mold temperature and a short cycle time requires a low mold temperature for faster solidification of the injected plastic melt, accurate temperature control is obviously of the utmost importance. Cycle times of 2.0-2.6 seconds have been achieved for DVDs. Nowadays, when adjusting the temperature, the radial deformation of the molding is taken into account. In the manufacturing process, depending on the disk format, the temperature of the tools must be within a temperature range of approx. 40 ° to 145 ° C - eg approx. B. 120 ° C during the DVD injection molding process. Even deviations of only 0.5 to 1.0 ° C can already lead to the fact that the resulting products are not usable. Precise temperature control is therefore crucial for effective production.

The object of the invention is to provide housing bodies for mechatronic lifting body To improve flow measuring devices as well as mechatronic lifting-flow measuring devices, in particular those for tempering of / for injection molding and thermoforming plants or Ur- or forming devices, the fast and precise fluid temperature and / or fluid quantity controls for the fluid-based tools and / or molding compositions of tempering or Ur- or forming facilities allow. This object is achieved by the features specified in the independent claims. Advantageous developments of the invention are set forth in the subclaims, the description and the drawings including the explanations of the drawings.

A block-shaped monolithic housing body for a flow-rate mechatronic lifting body flow measuring device has mutually perpendicular blind and / or through-holes in the x, y and z directions which intersect or overlap one another. As a result, a passageway of several passageway channel pieces is created for the fluid to be measured. In such an intersection region of a or each functional unit, a mechatronic flow measuring insert is fastened or screwed in the x-direction in a double, concentric blind hole forming the x-measuring channel, the fluid speed-dependent and fluid deflection-dependent Hubkörperauslenkung is detected by a magnetic field-sensitive or inductive proximity sensor. In particular, the housing body and the flow measuring device for high-temperature fluid applications has in the z direction at least one channel for cooling (possibly also for the heating or temperature control of the flow measuring inserts) and at least two mounting channels for fixing side by side arranged housing body, vzw. for directly and directly connected housing body. Significant features of the invention are: In the z-direction, a measuring fluid-relevant through or blind hole is provided as collecting sensor return in the sensor return, which is connected to the x and y channels. As a result, the connection costs are lower, because a multi-channel output is avoided. The invention can be used both in the flow and in the return of multi-channel temperature control of injection molding machines and other Ur- and forming equipment.

The basic ideas in a tempering a Ur- or forming device with a temperature control, with a mold to be tempered, wherein the mold has at least one fluid channel and at least in a channel a control valve for adjusting the flow rate and / or flow rate of the fluid and the control valve associated Hubkörper-Strömungsmessgerät, is to apply a certain basic principle with respect to the lifting body-based flow meters, flow devices and in a body fluid-tight screwed or fastened flow measuring inserts and the flow in the lifting body or valve seat targeted by a larger angle in one direction only or in two to deflect opposite directions, so that the direction of flow of the fluid is not equal to the outflow direction, d. H. the deflection direction of the lifting body differs from the outflow direction by a specific angle of 90 degrees. Furthermore, various advantageous fluid body or housing body or housing bell are presented, which differ mainly in terms of fluid channel design and fluid management. The various cuboid monolithic housing bodies for a flow-rate mechatronic lifting-body flow measuring device have mutually perpendicular blind and / or through-holes in the x, and y directions, which intersect or overlap one another. As a result, a passageway of several passageway channel pieces is created for the fluid to be measured. In such an intersection region of a or each functional unit, a mechatronic flow measuring insert is fastened or screwed in the x-direction in a double, concentric blind hole forming the x-measuring channel, the fluid speed-dependent and fluid deflection-dependent Hubkörperauslenkung is detected by a magnetic field-sensitive or inductive proximity sensor. In particular, the housing body and the flow measuring device for high-temperature fluid applications has in the z direction at least one channel for cooling (possibly also for the heating or temperature control of the flow measuring inserts) and at least two mounting channels for fixing side by side arranged housing body, vzw. for directly and directly connected housing body.

Below are advantageous flow measuring inserts for the invention 1 based on several, even in the 1 - 5 illustrated advantageous embodiments explained in more detail:
An advantageous variant of the invention is that the output unit 300 , which outputs a signal signal relevant output signal as a standard signal via a plug or cable output, outside the housing 3b the medium-near measuring unit 4 arranged and with this over a flexible cable 200 connected. The output unit 300 with a built-in electronics unit (eg with for short-circuit protection, electro-optical indicators, display and programming logic, etc.) that receives the signal from the sensor unit 21 processed and converted into a standardized signal and outputs to a subsequent unit such as a PLC, is integrated in known mechatronic Hubkörperströmungsmessgeräten in the proximity switch or an Analognichtsungssensorgerät, which have the usual display elements such as LEDs in these devices. Especially for high media temperatures, it is advantageous, the output unit 300 as a separate unit (device, module) to realize, because thereby an output unit 300 with integrated evaluation unit or evaluating electronic unit, possibly also with a programming, operating and / or display unit, with a standardizable, the medium-sized part of the flow measuring insert 1 independent part, which is universally applicable and in high temperature applications much less temperature and medium loaded (thermal, chemical and mechanical resistance and impermeability). In order to achieve low interference or good reliability and media and moisture resistance, it is advantageous to electrically contact both units by means of a non-pluggable flexible connection (cable), ie not to use plug-in connectors, preferably also no cable connection compartment.

A further preferred embodiment of the invention is that the flow measuring insert consists essentially of three coaxial circular hollow cylinders, which are screwed together, wherein the inner the heat conducting sleeve, the middle of the insulator sleeve 10i , which is at the same time guide sleeve for the Hubkörpereinheit and / or the lifting body spring, and the outer of the housing shell 3b6 is, with the medium housing, z. B. a brass Y-piece or brass angular seat valve housing with valve seat is screwed as lifting stop. The device is thus particularly stable and effective and inexpensive to produce.

A further preferred embodiment of the invention consists in the transducer unit 21 , with which the position of the lifting body 18a by means of an attached thereto or rigidly connected to this influencing element 20 is detected, at least on the medium side with a To encase thermal insulator or semi-insulator, which protects against the hot medium. Inevitably, due to its limited insulating capability and the construction caused by the sensor principle of the electronic proximity sensor or switch used, and the relatively thin wall thickness of the guide sleeve, which is technically and sensorically dependent 18b1 Nevertheless, at a medium temperature of more than 120 degrees Celsius, a lot of heat in its interior, so that the sensor or the Meßaufnehmereinheit is still strongly heated. Second, this transducer unit 21 thermally with a heat conducting body 7 coupled, which is designed so that its outer part, at least a part thereof, part of the outside of the housing 3b of the flow measuring insert 1 is. Instead of the critical unit, the sensor unit 21 To further remove from the hot medium, which would result in a loss of sensitivity and measurement accuracy, thus another, better way was recognized, which avoids these disadvantages. As the heat-conducting body 7 a higher, in particular a significantly higher thermal conductivity than the insulating unit 5 has (the difference should be as large as possible), the medium heat or residual heat, which is to this transducer unit 21 over the thermal insulator or the insulation unit 5 gets into the heat conducting body 7 including one or more of its outer parts 7a1 . 7b derived and at least from one of these outer parts 7a1 . 7b the medium heat are delivered to the environment of the housing. The heat-conducting body 7 is preferably hollow cylindrical, in particular circular hollow cylindrical, formed with a solid shell and is completely closed at the medium end. This allows the transducer unit 21 , which in the simplest case can only consist of the transducer, at or in the end of the heat-conducting body 7 or a Wärmeleithülse 7a to install and the electrical leads (cables 200 ) in the heat conducting body 7 respectively. This is particularly convenient, since the thickest possible Wärmeleitkörper 7 advantageously over the back 3b5 of the housing 3b led out and with it comes the cable 200 far away from the hot medium or hot parts to the surface. Thus, an effective mechanical and thermal protection, especially kink protection, given. As part of the heat-conducting body 7 or the Wärmeleithülse 7a now part of the extended case 3b is the flow measuring insert or device, the heat dissipation through the increased heat capacity and heat conduction is better, even by the long, but still relatively thin flexible strand of the connecting cable 200 , but the heat dissipation by air convection and heat radiation is mainly due to the greatly enlarged surface of good heat conducting areas of the device 4 Improved with direct air contact (housing surfaces), especially because the heat dissipation to the environment in the medium range of the device 4 he follows. Thus, the invention is suitable for high temperature applications, in particular from about 120 to 200 ° C and beyond, as for example in oil or high pressure water media at tempering 500 can occur from original and forming machines. Such temperatures in the direction of 200 ° C and above occur, inter alia, when tempering the tools or mold halves of injection molding machines. Preferably, the heat-conducting body 7 , especially the heat conducting sleeve 7a , of copper, in particular of a high-purity copper with a thermal conductivity greater than 300 W / Km, and the thermal insulator sleeve 10i made of a temperature-resistant plastic, preferably PPS, POM or PEEK.

Hereinafter, particular embodiments of the invention with reference to the 1 to 5 explained in more detail, the various advantageous variants of flow measuring inserts 1 , in particular high temperature fluid resistant, relate to:
In 1 shows a mechatronic flow measuring device, consisting of a flow measuring insert 1 with a measuring unit 1c in a medium housing 3a with ¾-inch threaded connection 3a1 is screwed. In the case 3b is a guide sleeve 10 arranged, to a large extent, out of the housing 3 protrudes. On the guide sleeve 10 is a sliding element 12 or a Hubkörpereinheit 18 slidably mounted. The sliding element 12 can counteract the force of a spring 14 in the direction of the housing 3 be moved. The sliding element 12 consists of a guide tube 16 made of copper and an adapter 18 from PPF. In the adapter 18 becomes a magnet 20 held, which has a relatively high Curie temperature. In the leadership axis 10 is the heat conducting sleeve 7a screwed. In the interior at the front end of the Wärmeleithülse 7a there is a sensor unit 21 , preferably a GMR sensor with preprocessing electronics, mounted on a sensor board 24 is attached.

The output unit 300 points next to a cylindrical housing 330 and a signal output 310 , z. B. a cable or plug output, at least one electronic unit 320 on which the signal from the sensor unit 21 or the sensor processed and converted into a standardized output signal and outputs to a subsequent unit such as a PLC, possibly also display elements such as LEDs. If necessary, the electronic unit also assumes the programmability and / or operability (wired and / or by means of switches or potentiometers on the evaluation unit). The evaluation unit is not, as in conventional solutions, in the actual measuring device, in this case in the measuring unit 1c integrated, but preferably over a conventional two-, three- or vieradriges flexible cable 200 , z. As a standard PVC or a heavy duty rubber cable, with the measuring unit 1c connected. The output unit 300 has a plug connection on the output side 310a on, z. B. a three- or four-pole M8 or M12 circular connector so that it can be connected directly and inexpensively with the subsequent unit. Through this modular and the other modular structure of the flowmeter 1 can the output unit 300 universally designed and used for many applications. At the same time, by the preferably modular construction of the measuring unit 1c in particular by the use of three main sleeves screwed together 3b6 . 10 . 7d / 7a and the modular lifter unit 18 These can be easily and individually adapted to the medium and measuring conditions on site. Possibly. can the flexible cable 200 also via a connector, not shown, with the output unit 300 get connected. This gives even more flexibility with regard to the selection and use of output unit 300 and cables 200 (Length, material, etc.). Especially in high-temperature applications, it is advantageous if the space within the measuring unit 1c for Temperaturableitmittel or the heat-conducting body 7 and can be used for the mechanical and thermal stability of this unit. Another advantage arises in particular in the use of inexpensive flexible cables, which usually have a PVC sheath, which are either not usable at high temperatures or mechanically less resilient. By using a heat conducting body 7 That's about the back front 3b5 goes out (Outer part 7b ) and in which the cable 200 is guided, the exit point is in the area of the rear exit 7a1 or the kick protection 210 Low temperature load, possibly also little media loaded by possibly leaking hot medium, so that the flow meter 1 or the flexible cable 200 In this area better tolerates mechanical and chemical stress or the use of inexpensive cable is possible. The output unit 300 is far away from the hot medium and therefore only exposed to conventional temperature loads. Again, this does not require the use of temperature-resistant and expensive materials for housing, electronics and others.

The medium housing 3a , usually made of brass, has a total of three nozzles 3a4 with three threaded connections, with two medium-side threaded connections 3a1 and a flow meter insert side 3a2 available. The flow direction 2 of the liquid or gaseous medium to be measured is indicated by an arrow. Out of the one with a lid 3b1 closed housing 3b the medium side part of the measuring unit 1c protrudes a heat conducting body 7 in the form of a copper or brass Wärmeleithülse 7a in which the connection cable 200 to be led. The end of the heat conducting sleeve 7a has a kink protection 210 for the flexible connection cable 200 on. It is beneficial to bend protection 210 and the outer part 7b the Wärmeleitkörpers 7 to perform in one piece, with copper is particularly suitable and the wall thickness of the anti-buckling is designed to be thin, so by enclosing pressing means of a multi-segment tool kink protection in conjunction with an excellent liquid-tight connection with the more or less elastic cable 200 can be achieved without the separate measures for the permanent tightness in this area must be affected or a more extensive use of materials in the form of special seals is necessary.

In 2 is a sectional view of the mechatronic flowmeter 4 with a corresponding flow measuring unit 1c or flow measuring insert 1 according to 1 shown enlarged. In the housing shell open at the bottom 3b6 is a closed bottom guide sleeve 10 made of temperature-resistant, but thermally poorly conductive material such as PEEK or PPS screwed in, which is the essential part of the insulation unit 5 represents the sensor unit 21 to protect against the heat of the medium. A sealing element 1la In the form of an O-ring prevents the medium from reaching the screw connection or from escaping from the device. Between middle (guide sleeve 10 ) and outer 3b6 Sleeve is a narrow annular cavity 15 for the spring 14 and the guide tube 18b , This guide tube 18b can itself, especially in the case of the use of an inductive proximity sensor or a coil or LC or LR oscillator as a sensor unit 21 , the influencing element (according to the magnet 20 ) for the sensor unit 21 be or may include such an influencing element or resonant circuit damping element. The influencing element is then designed as a damping ring, which advantageously consists of non-magnetic stainless steel. In the present case is a GMR sensor unit 21 as an integrated component with a magnet as an influencing element 20 shown, with the lifting body 18a the Hubkörpermodul 18 (with feather 14 and guide tube 18b ) is firmly connected or sealed in, so that no fluid contact due to possible corrosion or contamination of the medium is present. It is common in magnetic sensors, in contrast to inductive measuring devices, that the measuring element or the sensor has preprocessing electronics, which together with the measuring element form a compact or integrated unit. Sensor package 20 may mean for the purposes of this invention that preprocessing electronics is integrated in this or the sensor unit only the sensor, z. B. a sensor coil having. Magnetic field-sensitive sensors in the sense of the two described methods or sensor types are particularly suitable for high-temperature applications, since they are robust and dirt-resistant especially to optical and capacitive methods.

• a) der mediumsseitig offene Gehäusemantel 3b6 als äußere Hülse, die mittels eines unteren Außengewindes 3b6a und des Dichtungselementes 26 mediumsdicht in das Mediumgehäuse 3a eingeschraubt ist (3b6i, 10a);
• b) die mediumsseitig geschlossene Führungshülse 10 als mittlere Hülse, die in den Gehäusemantel 3b6 eingeschraubt ist (3b2, 10a), mittels des Dichtungselementes 11a abgedichtet ist und mit diesem Gehäusemantel 3b6 einen hohlzylinderförmigen Hohlraum 15 zur Führung des Führungsrohres 18b der Hubkörpereinheit 18 und/oder zur Führung der Feder 14 bildet. Für hohe Mediumstemperaturen ist die Führungshülse 10 aus hitzebeständigem thermisch isolierenden Material, insbesondere einem Kunststoff wie PEEK oder PPS, gebildet;
• c) die Messaufnehmerhülse in Form einer Wärmeleithülse 7b, die an oder in deren mediumsseitiger Spitze die Messaufnehmereinheit 21 trägt und die in die mittlere Hülse, d. h. die Führungshülse 10 eingeschraubt ist (7a2a, 10b). Die Abdichtung erfolgt optional mittels des Dichtungselementes 11b. Für hohe Mediumstemperaturen von mindestens 120 bis 200 Grad Celsius ist diese Messaufnehmerhülse 7d als wärmebeständige und hochwärmeleitfähige Wärmeleithülse 7a ausgebildet (vorzugsweise mit einem einstückigen Mantel aus hochreinem Kupfer mit einem Wärmeleitkoeffizient größer als 300 W/Km und über die Rückfront 3b5 hinausragend), die durch den guten thermischen Kontakt mit der Messaufnehmereinheit 21 deren Wärme in den rückwärtigen Teil der Wärmeleithülse 7a transportiert, ggf. auch in einen sekundären Wärmeleitkörper 7, z. B. in eine vierte Hülse, die als Deckel 3b1 und Kontermutter ausgebildet ist. Durch den modularen Aufbau mittels dreier Haupthülsen, kann das Messgerät 1c oder einzelne Teile desselben wie die Wärmeleithülse 7a mit der Messaufnehmereinheit 21 sehr schnell ausgewechselt werden, z. B. im Fehlerfall. Es reicht dann, diese kleinere Einheit, d. h. eine der drei Haupthülsen auszuwechseln.

As already mentioned, the meter is 4 with his measuring insert 1 particularly advantageous due to its modular design. On the one hand, the Hubkörpermodul 18 easily be replaced by another or individual components like the spring 14 , the guide tube 18b or the lifting body 18a be replaced. On the other hand results in a greater universality and inexpensive manufacturability of the flow measuring insert 1 or the flowmeter 4 by the modular construction by means of three coaxial, screwed together and overlapping main sleeves, which are above the lifting body 18a are located. these are

• a) the medium side open housing shell 3b6 as an outer sleeve, by means of a lower external thread 3b6a and the sealing element 26 medium-tight in the medium housing 3a is screwed in ( 3b6i . 10a );
• b) the medium side closed guide sleeve 10 as a middle sleeve, in the housing shell 3b6 is screwed in ( 3b2 . 10a ), by means of the sealing element 11a is sealed and with this housing shell 3b6 a hollow cylindrical cavity 15 for guiding the guide tube 18b the Hubkörpereinheit 18 and / or for guiding the spring 14 forms. For high media temperatures is the guide sleeve 10 made of heat-resistant thermally insulating material, in particular a plastic such as PEEK or PPS;
• c) the sensor sleeve in the form of a Wärmeleithülse 7b , which at or in the middle-side tip of the sensor unit 21 carries and in the middle sleeve, ie the guide sleeve 10 is screwed in ( 7a2a . 10b ). The sealing takes place optionally by means of the sealing element 11b , For high media temperatures of at least 120 to 200 degrees Celsius, this sensor sleeve 7d as a heat-resistant and highly heat-conductive Wärmeleithülse 7a formed (preferably with a one-piece jacket of high-purity copper with a heat transfer coefficient greater than 300 W / Km and on the back 3b5 protruding) due to the good thermal contact with the sensor unit 21 their heat in the rear part of the Wärmeleithülse 7a transported, possibly also in a secondary heat-conducting body 7 , z. B. in a fourth sleeve, as a lid 3b1 and lock nut is formed. Due to the modular construction by means of three main sleeves, the measuring device can 1c or individual parts of the same as the Wärmeleithülse 7a with the sensor unit 21 be replaced very quickly, for. B. in case of error. It then suffices to replace this smaller unit, ie one of the three main sleeves.

The guide sleeve 10 as the main component of the insulation unit 5 made of thermally insulating material, helps against the temperature load on the sensor unit 21 , However, if a lot of hot medium is flowing or the temperature is very high, this measure will help little since it has been recognized that the heat sink capability of conventional mechatronic flowmeters is low. For this reason, the use of an insulating unit 5 or a thermally insulating guide sleeve 10 with a low coefficient of thermal conductivity with the use of a Wärmeleitkörpers 7 with a high coefficient of thermal conductivity within the guide sleeve 10 combined. In the guide sleeve 10 is a heat conducting body from above 7 in the form of a closed bottom and open top Wärmeleithülse 7a screwed in with great wall thickness and thus very low thermal resistance. At least their coat is usefully one piece, z. B. as a rotary or deep-drawn part made of copper, is designed to prevent heat conduction barriers or zones with reduced thermal conductivity. The lower end of the Wärmeleithülse 7a is sealed with a brazed copper lid. On the lid or in the heat conducting sleeve 7a is the sensor unit 21 with a circuit board 24 arranged, which has a good thermal coupling to the lid or to the Wärmeleithülse 7a has, for. B. by a potting or adhesive, which is usefully electrically isolated, but thermally well conductive (thermal grease). To the circuit board 24 are the strand 22 of the flexible cable 200 soldered through the heat conducting sleeve 7a is guided (at least their veins). The heat-conducting body 7 Although the main component of the insulation unit 5 , but also the Hubkörpermodul 18 with the guide tube 18b (The pressure shock absorption a damping opening 6 and when using a magnetic proximity sensor made of copper, brass or a high-temperature workpiece such as POM, PEEK or PPS), and the only narrow channel 15 in which the spring 14 , which helps to control the temperature gradient from the main flow of the medium to the sensor unit 21 as big as possible. The heat-conducting body 7 is designed so that at least one part (outer part 7b ) from it to the outer surface of the housing 3b of the measuring unit 1c belongs, in particular to the medium remote surface. This allows much more heat through the measuring unit 1c or the flow measuring insert 1 be delivered to the environment (in part, via the electrical leads of the flexible cable 200 ). This happens mainly through heat convection and radiation. This is realized by the massive, heat-resistant heat-conducting sleeve 7a that with her outer part 7b to about the back front 3b5 extends. The back front 3b5 is here in the particularly preferred embodiment by a lid 3b1 formed in the form of a metal nut, which is also counter nut. Through its internal thread 3b1i and the traction with countering results in a low thermal resistance to the primary Wärmeleithülse 7a so that the lid 3b1 an outer heat-conducting, -konvektierender and -strahlender housing part 3b7 and secondary part of the heat-conducting body 7 is, at the same time, a hollow cylindrical housing nut with internal thread 3b1i , The housing jacket 3b6 and the guide sleeve 10 are made of a poorly heat-conductive material such as PPS (polypropylene sulfide) with a heat transfer coefficient of about 0.3 W / K m.

The in the Y-fitting or the connection unit 100 flowing medium surrounds a part of the guide sleeve 10 which can have any cross-sectional shape. But it has some technical and economic advantages in circular hollow cylinder-shaped training. Due to the high temperature of the medium up to 200 ° C and above, despite the poor thermal conductivity of PPS residual heat from the guide sleeve 10 in the direction of the heat-conducting sleeve 7a transported. The guide sleeve 10 serves as a thermal insulator, which has a finite thermal resistance. Due to the very high thermal conductivity coefficient of the Wärmeleitkörpers 7 , the preferred as circular hollow cylindrical heat conducting sleeve 7a is executed, but the heat is good for medium-distant end of the Wärmeleithülse 7 transported away, where it is discharged into the environment to the outside. This can ensure that the sensor unit 21 not more than 90 ° C warm. In addition to a sensor unit 21 or a sensor for an influencing element 20 in the form of a permanent magnet, for which a GMR sensor or GMR sensor is particularly suitable, is for detecting the position of the sliding element 12 or the moving lifting body 18a the Hubkörpereinheit 18 Alternatively, other sensor types conceivable. In particular, inductive proximity sensors or inductive proximity switches are very suitable, especially when the principle of Außenringbedämpfung is used that allows very small hystereses very high accuracies, especially switching accuracy. Alternatively to POM can be used as the material for the housing 3c and the guide sleeve 10 Also PPE or PEEK can be used.

3 shows a flow measuring insert 1 that in contrast to the 1 to 2 a larger secondary heat conduction body 7 in the form of a metallic lid 3b1 with internal thread 3b1i having. This provides better cooling of the sensor unit 21 guaranteed. The elongated housing jacket 3b6 is also made of thermally insulating material, so that no unwanted thermal bridges with low coefficient of thermal conductivity parallel to the thermal bridge medium sensor unit can arise. Also, the lifting body is slightly conical and specially designed, so a high dynamic range of over 1: 100 can be achieved. This means that a flow rate range of less than 100 ml / min to over 100 l / min can be monitored or measured without changing the lifting body or the Hubkörperform. By in the angle seat valve housing Y-Fitting or in the connection unit 100 flowing medium or fluid (liquid or gas) is the sliding element 12 or the lifting body 18a depending on the flow rate of the medium more or less in the direction of the fluid-remote end of the measuring unit 1c or the housing shell 3b6 of the housing 3 pressed. With the help of the wire 22 contacted sensor element or the probe or the probe unit 21 becomes the location of the influencing element 20 , ie the magnet, and thus the position of the sliding element 12 or lifting unit 18 on the guide shaft or the guide sleeve 10 detected and the corresponding measurement signal by means of an evaluation further processed, possibly linearized and / or a switching point or multiple switching points generated and output, preferably as a standard signal in the form of a switching signal and / or digital signal and / or a conventional analog signal, eg. 0-10V or 4-20mA. When the mechatronic flow use 1 is installed in a hot environment, which mainly relates to high-temperature fluid applications, is a water cooling means of the heat conduction 7 or the Wärmeleithülse 7a provided, as well as the 4 and 5 demonstrate. Therefore, this protrudes considerably less or not at all out of the housing 3c out, which allows small footprint for tight spaces. The invention is particularly suitable for temperature control devices for high-temperature injection molding devices or injection molding machines. The medium or fluid (water, oil or glycol) has a temperature of about 80 to 200 ° Celsius and has a pressure of about 3 to 20 bar. With the mechatronic flow measuring insert according to the invention 1 and a flowmeter based thereon 4 the quantity of the flowing medium can be detected very precisely and with little inertia (reaction times of less than 30 to 10 ms!) and the process can be regulated precisely and quickly or finely. This can be accurately determined with an additional temperature sensor, the heat input or the heat dissipation in and out of the injection mold and thus the injection molding process can be optimized.
