The invention provides a mold for manufacturing a high-
voltage combination switch CT shell and a use method thereof, belonging to the field of mold technology, comprising a
processing table, an annular plate, a mold core, a mold shell, an injection
pipe, an injection molding mechanism and a vibration mechanism. The invention drives the annular frame to descend through a lifting cylinder, so that the injection molding
pipe is firmly connected to the injection
pipe, and the notch on the inner wall of the injection molding pipe makes the connection between the injection molding pipe and the injection pipe more sealing, thereby improving the injection effect of the CT shell
raw material. The injection molding pipe is lifted and lowered following a support ring, so that the injection molding pipe and the injection pipe can be connected synchronously, thereby improving the synchronization effect during the injection of the raw materials. The outer wall of the mold shell is conveniently hammered by an elastic hammer on a conical wheel to generate vibration and accelerate the
precipitation of the injected raw materials. At the same time, the annular tooth plate drives the fixed shell to rotate around the mold shell, and the annular frame drives the annular tooth plate and the fixed shell to lift and lower, so that the elastic hammer can fully hammer the mold shell around, thereby improving the injection molding efficiency and quality of the CT shell.
