    The present invention relates to a temperature control device for a molding tool or components of a shaping work machine having the features of the preamble of claim 1 and a method having the features of claim 10.
    The following discussion of the prior art is made by way of example with reference to an injection molding machine as a special case of a molding machine and an injection molding of such an injection molding machine as an example of a mold of a general forming machine. The disclosure of the following application is not limited to this special case.
    By tempering is understood in the present application cooling or heating.
    In the prior art, the at least one pump is operated at a constant capacity. In this case, one either uses the flow rate (delivery rate or pressure, etc.) and the hydraulic resistance of the at least one branch line resulting flow rate or it uses chokes to achieve a desired lower flow rate.
    This results in several disadvantages: - Constant high energy consumption, - Reduced service life of the pump system, - Costs for the return temperature of the temperature control medium due to an excessive volume flow, - Higher leakage susceptibility and - Unnecessarily high pressure in the temperature control system.
    The object of the invention is to at least partially overcome the disadvantages described above.
    This object is achieved by a temperature control device having the features of claim 1 and a method having the features of claim 10. 2/15 73440 32 / fr
    By the invention, the above-described in the prior art mandatory throttling can be reduced or even eliminated. Since the energy consumption is proportional to the product of flow rate and pressure loss, eliminating the restriction has a positive effect on energy consumption.
    Advantageous embodiments of the invention are defined in the dependent claims.
    As a tempering preferably water (gaseous or liquid) or oil is provided. However, other fluids such as carbon dioxide or nitrogen may also be used. The tempering medium can be conveyed continuously or in pulses.
    It is particularly preferred that the tempering device is designed as a side-by-side device for a shaping working machine and has one or more tempering branches. The Beistellvorrichtung can either be arranged freestanding next to the forming machine or built on this.
    Particularly preferably, at least two tempering branches are provided, which are preferably connected in parallel.
    In order to make the regulation or control as good as possible, at least one sensor can be provided in each of the at least two tempering branches, by which at least one of the variables from the group temperature, flow rate, pressure, heat quantity, temperature difference, pressure difference can be detected, wherein signals the sensors of the control or regulating device can be fed.
    The easiest way to control the pump can be designed by these is controlled or controlled by their speed.
    In the event that the pump system comprises more than one pump, it may be advantageous, alternatively or in addition to the regulation or control of the 3/15 73440 32 / fr 73440 32 / fr • ·: 3 · · · · · ·
    Pump (s) individual pumps of the pump system can be switched off and / or activated. This would result in a kind of stage control or regulation.
    For individual regulation of the flow rates in the Temperierzweigen can be provided in each of these at least one throttle device. The throttle device may be adjustable, for example, manually or by the control or regulating device. The throttle device may be, for example, a flow valve whose flow rate is infinitely adjustable.
    Protection is also sought for a forming machine, in particular injection molding machine, die casting machine or pressing machine, with a tempering device according to the invention.
    Furthermore, protection is desired for an arrangement having at least two shaping working machines and a tempering device according to the invention, wherein the forming tools of the at least two shaping working machines can be tempered serially or in parallel by the tempering device.
    Since this is particularly energy-efficient, it can be particularly preferably provided that each tempering branch is individually throttled, wherein at least one of the tempering branches is at least substantially not throttled. By adapting the flow rate (delivery rate or pressure, etc.) to the flow requirement of this non-throttled temperature control branch, the pump can run with the lowest possible energy expenditure.
    The control or regulating device can be part of the
    Injection molding machine control, an external control, Beistellvorrichtung or a central host computer system.
    The pump system may be part of the injection molding machine, a Beistellvorrichtung or a central media supply. 4/15 • * Λ • • * * • • • • • • • · 73440 32 / fr
    Further advantages and details of the invention will become apparent from the figures and the associated description of the figures.
    1 shows a schematic representation of a tempering device 14 according to the invention. It has two tempering branches 2, 2 ', which lead through a forming tool 3. In the Temperierzweigen 2,2 'are also flow sensors 7, 4 temperature sensors and flow valves 15 available. Of course, the flow sensors 7 can also be designed as a component together with the flow valves 15. Furthermore, a control or control device 1 is provided - in this embodiment, a control device. This is connected to the flow sensors 7, the temperature sensors 4 and the flow valves 15. The temperature sensors 4 represent an alternative to flow measurement.
    The two Temperierzweige 2, 2 'are each connected to the flow 5 and the return 6. A pump 13 conveys tempering from the return line 6 in the flow 5. Furthermore, an optional heat exchanger 16 is arranged in the return 6. The pump 13 is connected to the control device 1 for control.
    FIG. 2 is a flowchart to illustrate a particularly preferred embodiment of a method according to the invention. In this case: i ... consecutive number of the temperature control branches 2 n ... number of used temperature control branches 2 X, ... output level of the flow valve 15 in the temperature control branch i [%] V (... volume flow in the temperature control circuit i F ... flow rate pump system
    The tempering branch i *, which remains at least approximately 100% open, can be displayed to a user as a branch determining the whole system ("bottleneck"). As a result, the user has the option of the hydraulic resistance of this temperature control branch 2, 2 ', for example, by 5/15 73440 32 / fr • · · · · · · · · · ·
    Removing quick couplings or reducing hose lengths targeted to reduce. Thereby, the flow rate of the pump 13 can be further reduced while opening the flow valves 15 of the other Temperierzweige 2,2 '.
    In contrast to FIG. 1, only one tempering branch 2 is provided in FIG. The tempering device is designed as a side-by-side device. In a common housing 20 are arranged: - pump 13 - flow sensor 7 - tank 17 for tempering - heating 18 for heating the temperature in the tank 17 - cooling 19 for cooling the temperature in the tank 17 - optionally a temperature sensor 4 and - a control or Control device 1.
