Abstract

The invention relates to a method used for monitoring a temperature control device of dies of an injection molding machine or a die-casting machine. The temperature control device (1) comprises an inflow end (3) and a backflow end (6), and at least two branch pipelines (4,5) which are connected in parallel with the inflow end and the backflow end on a flowing technology. Each of the at least two branch pipelines (4,5) is provided with a flow sensor (8,8'). Through comparing measuring data provided by the flow sensor (8,8'), pressure surge in the inflow end (3) and the backflow end (6) are separated from existence of leakage.

Description

technical field The invention relates to a method for monitoring a temperature-regulating device of a mold of an injection molding machine or a die-casting machine, the temperature-regulating device comprising an inflow end and a return flow end, at least two branch lines being arranged in flow-technical parallel connection at the inflow end A flow sensor is arranged in each of the at least two branch lines between the flow end and the return end. Background technique Molds for plastics processing are usually provided with a channel system which has at least one inflow end, one return end and branch lines (channel loops) arranged in between. This channel system allows fluid to enter the areas within the mold where energy is to be supplied or conducted away. In many plastics processing methods – and thus also in injection molding – it is important to be able to influence the temperature in individual areas of the mold in a targeted manner, so that the entire channel system ...
