Runner Optimization Of Hpdc Coolant Pump Housing Component Through Flow Analysis

Abstract

Die casting is an age-old process where molten metal is poured into a cavity containing the impression of the desire output to get a casted component as the final results. This process when done with the help of casting machines, involves additional process parameters such as injection pressure, clamping force, etc. An integral part of this process is also the runner design which delivers the molten metal from the barrel of the machine to the cavity of the mould. Two variations of runner design are implemented into the coolant pump housing component. The first design is a simple vertical shot runner design with sub-runners at 2 local regions. The second design is tilted shot runner design with gating points at 4 local regions. The fill time for the component is calculated based on an industrial thumb rule. Once the design and calculation is complete, the component shots are put through flow simulation and the obtained results are compared with each other and the manual calculations.
