1. A temperature control apparatus for a shaping tool or components of a shaping working machine, the temperature control apparatus comprising:
at least two temperature control branches connected to a feed for a temperature control medium,
a pump system including a pump for conveying temperature control medium in the feed,
a pump open-loop or closed-loop control device for open-loop or closed-loop control of a delivery output of the pump system,
at least two throttle devices, each of the at least two throttle devices being configured to have a variable degree of opening for throttling a quantitative through-flow of the temperature control medium in a respective one of the at least two temperature control branches, and
an open-loop or closed-loop control device having a degree of opening of each of the at least two throttle devices as a setting value, and having a control variable selected from a group including: the degree of opening of each of the at least two throttle devices, a temperature, a temperature difference, a through-flow, or a pressure,
wherein the pump open-loop or closed-loop control device is configured to control an operation of the pump so as to adjust the delivery output of the pump system depending on a control signal indicating the degree of opening of each of the at least two throttle devices.
 
10. A method of temperature control of a shaping tool or components of a shaping working machine, said method comprising:
providing at least two temperature control branches connected to a feed for a temperature control medium,
providing a pump system including a pump for delivery of the temperature control medium in the feed,
providing at least two throttle devices, each of the at least two throttle devices having a variable degree of opening for throttling a quantitative through-flow of the temperature control medium in a respective one of the at least two temperature control branches, and
controlling an operation of the pump of the pump system to adjust a delivery output of the pump system depending on the degree of opening of each of the at least two throttle devices, the controlling being closed-loop control.
