Embodiment Construction

[0036] figure 1 The throttle device 6 and the throttle valve adjusting device 7 for adjusting the opening degree of the throttle device 6 and the pump system 4 with the pump adjusting device 5 for adjusting the delivery volume of the pump system 4 are shown schematically.

[0037] The two control circuits are thus combined with each other, as the instantaneous opening of the throttle device 6 (as an example of a control parameter) is transmitted from the throttle valve adjustment device 7 to the pump adjustment device 5, while the instantaneous delivery of the pump system 4 The quantity represents the disturbance parameter acting on the throttle device 6 . As an alternative, the control parameters can of course also be transmitted from the throttling device 6 to the pump regulating device 5 .

[0038] figure 2 Shown is a tempering device 1 for a mold 14 of a molding machine not shown in detail, which has three tempering branches 2, 2', 2" as examples here (tempering branche...

Abstract

A temperature control apparatus includes a temperature control branch connected to a feed line for a temperature control medium, a pump system including a pump for conveying the medium, a pump open-loop or closed-loop control device for controlling the output of the pump system, a throttle device having a variable degree of opening for throttling a quantitative through-flow of the medium in the temperature control branch, and an open-loop or closed-loop control device with the degree of opening of the throttle device as a setting value and with a control variable from the group: degree of opening of the throttle device, temperature, temperature difference, through-flow, pressure or a physical value to be derived from that group. The pump open-loop or closed-loop control device provides for open-loop or closed-loop control of the delivery output of the pump system depending on the degree of opening of the throttle device.

Description

technical field [0001] The invention relates to a tempering device for molds or components of a molding machine with the features of the preamble of claim 1 , a molding machine with such a tempering device and a device for molding with the features of the preamble of claim 11 A method for regulating the temperature of molds or components of molding processing machines. Background technique [0002] The following discussion of the prior art takes place for example with the aid of an injection molding machine as a special case of a molding machine and with reference to the injection mold of such an injection molding machine as an example of a mold for a general molding machine. However, the disclosure of the following application is not limited to this particular case. [0003] In this application, tempering is understood as cooling or heating. [0004] In the prior art, at least one pump is operated in a regulated manner with a constant delivery output or rotational speed. ...
