- Abstract:
-
Injection mold cooling pipe network calculation can accurately predict the coolant pressure and flow rate of the pipe network. At present, there are two basic calculation methods with shortcomings: the loop method is cumbersome and the iteration speed is slow; However, the traditional nodal method has a singular liquid conduction matrix when the pipeline flow rate is zero. According to the basic equation of pipe network, a new mathematical model is established and an improved node method is proposed. The calculation program block diagram is given, and the computer calculation program is written, the new method effectively overcomes the shortcomings of the traditional method, and the case calculation shows that the analysis and calculation of the injection mold cooling pipe network can be carried out quickly and accurately.
