Calculation of Initial Ejection Force in Basin Type Insulator Epoxy Injection Mould

Abstract:

It is of great significance for the design of ejection mechanism and the control system of automatic ejection machine that the initial ejection force of injection mould can be calculated. According to the production status of basin type insulator epoxy injection mould, the influencing factors on the ejection force were analyzed. The calculating formulae of initial ejection force for cavity with different structures were derived and verified using methods of mechanics analysis, arithmetic average and the thoughts of molding mechanical performance submits Hook’s law. The verification result shows that the initial ejection force can be better estimated and used as a reference to design.
