Abstract

The flow distribution of the cooling channel in the hot stamping mold will directly affect the quality of the formed parts in a mold multi-cavity mold. In the actual hot stamping production, the production workers need to monitor the flow of each inlet in real time, but it is often difficult to determine how the cooling water flow after the water valve regulation is redistributed to the various chambers. In this paper, the equivalent water resistance concept based on the principle of equivalent circuit is proposed, which aims to solve the problem of flow distribution of each cavity in one mode and multiple cavities, and to ensure the uniformity of the mold temperature of the parts after the cavity is formed. Firstly, a database of the relationship between the inlet pressure and the flow characteristics of the simple equivalent pipeline is established; After that, a set of multi-cavity complex molds is selected for analysis to obtain the characteristic relationship between the inlet pressure and the flow rate of the cooling channel; Finally, the characteristic curve of the equivalent pipeline is compared with the pressure flow characteristic curve of the complex waterway to obtain the simple equivalent pipeline corresponding to the multi-cavity mold. Using the hot stamping simulation analysis method, the flow distribution of simple equivalent pipelines is based on the characteristics of tandem waterways.
