Embodiment Construction
[0030] This embodiment provides a method for adjusting the runner balance of a multi-cavity mold. Before executing this method, first use the same parameters (including flow rate, throttle valve opening, etc.) figure 1 Inject the raw material into the 8 cavities of the mold shown to form 8 short shots, and then start to carry out the method, such as figure 2 As shown, this method includes:
[0031] S1. Obtain the quality of each short shot formed by pouring fluid raw materials into multiple cavities of the mold, that is, obtain the quality of the short shots manufactured by using the above mold cavities F1-F8, where the short shot refers to the material The product produced when the mold is not filled (0<fill rate<98%). In order to make the calculation results of the subsequent steps more accurate, the filling rate of the short shot is preferably 75%-95%.
[0032] S2. Calculate the mass ratio of each short-shot product to its corresponding complete product, wherein the comp...
