The working principle of Embodiment 1 is as follows: the casting chamber 1 in the vacuum continuous casting machine is a space for metal melting and injection. It is usually made of high-temperature resistant materials, such as ceramics or metals. The casting chamber 1 is equipped with a heating device and a nozzle. It is used to heat metal to the melting point and inject it into the mold. The vacuum system in the vacuum continuous casting machine is used to maintain a certain degree of vacuum in the casting chamber. It includes equipment such as vacuum pumps, vacuum pipelines, and vacuum gauges, which are used to extract and monitor the casting chamber. The gas ensures that the casting process is carried out in a good vacuum environment. The heating system in the vacuum continuous casting machine is responsible for heating the metal material to the melting point. Common heating methods include induction heating and resistance heating, which heat the metal through electromagnetic fields or currents to achieve Melting temperature, during the casting process, the raw materials are first added into the casting chamber 1, and then are cast and discharged from the bottom end of the casting chamber 1. At this time, the casting enters the inside of the fixed frame 15. At this time, the first two parts on both sides of the fixed frame 15 are started. An electric motor 18 drives the first driving gear 17 to rotate through the first electric motor 18.
