Abstract

Provided is a temperature control device having at least one temperature control branch connected to a feed, and a pump system including at least one pump for the delivery of temperature control medium in the feed. Additionally, the temperature control device is provided with at least one sensor by which at least one of the parameters from the group of temperature, through-flow amount and pressure can be detected, and a control or regulating device for regulating or controlling a delivery of the pump system, to which signals from the at least one sensor can be fed.

First claim

The invention claimed is:

1. A temperature control device for a shaping tool or component of a shaping working machine, the temperature control device comprising:
two temperature control branches connected to a feed;
two throttle devices respectively provided in the two temperature control branches;
a pump system including a pump for the delivery of temperature control medium in the feed;
a control or regulating device for regulating or controlling a delivery of the pump system; and
a sensor for detecting a parameter from a group of temperature, through-flow amount, and pressure,
wherein signals from the sensor are fed to the control or regulating device, and
wherein in at least one of the two temperature control branches, the throttle device provided therein is essentially completely open.

2. The temperature control device according to claim 1 , wherein the two temperature control branches are connected in parallel.

3. The temperature control device according to claim 2 , wherein each of the two temperature control branches includes a sensor for detecting a parameter from a group of temperature, through-flow amount, and pressure, wherein signals from the sensor included in each of the two temperature control branches are fed to the control or regulating device.

4. The temperature control device according to claim 1 , wherein the control or regulating device regulates or controls the delivery of the pump system by controlling or regulating the rotary speed of the pump.

5. The temperature control device according to claim 1 , wherein the control or regulating device regulates or controls the delivery of the pump system by shutting down or switching on the pump.

6. The temperature control device according to claim 1 , wherein the temperature control device is an accessory device for the shaping working machine.

7. A shaping working machine having the temperature control device according to claim 1 .

8. An arrangement comprising two shaping working machines and the temperature control device according to claim 1 , wherein the shaping tools of the two shaping working machines can be temperature-controlled by the temperature control device in a serial or a parallel relationship.

9. The shaping working machine according to claim 7 , wherein the shaping working machine is an injection moulding machine, a die casting machine or a pressing machine.
