[0002] EMU, also known as "EMU train", is a type of modern train, consisting of several powered vehicles (EMU) and non-powered vehicles (trailers). The train runs in a fixed marshaling mode within the normal service life. EMU train is a self-propelled fixed marshaling train. Compared with traditional trains, EMU has the characteristics of not changing the marshaling at will and turning back without detaching the locomotive. Among them, multi-power distributed EMU has the advantages of light axle weight, good acceleration performance, and flexible use. It is suitable for small-scale and high-density passenger organization. It is widely used in intercity rapid transit and urban rail transit trains. In the production process of the current EMU driving platform, molds need to be used for processing and production. The mold is a tool that makes the blank become a part of a specific shape and size under the action of external force.
