Description
Technical Field

Background
Centrifugal casting is a technique and method of injecting liquid metal into a mold that rotates at high speed, causing the molten metal to perform centrifugal motion to fill the mold and form a casting. Centrifugal casting is performed on a centrifugal casting machine in order to rotate the mold. Centrifugal casting machines can be divided into two types, namely vertical type and horizontal type, according to the different rotational space positions of casting molds. On a vertical centrifugal casting machine, the mold is rotated about a vertical axis. The inner surface of the casting is in a parabolic shape due to centrifugal force and the gravity of the liquid metal, so that the casting is thin at the top and thick at the bottom. The higher the height of the casting, the greater the wall thickness difference, with other conditions unchanged. Therefore, the vertical centrifugal casting is mainly used for casting with a diameter smaller than that of disc rings, and the wall thickness is uneven under the gravity of liquid metal, so that the cutting process is increased later. The horizontal centrifugal casting machine has casting mold rotating around horizontal shaft. The cooling conditions of all parts of the casting are approximately the same, so that castings such as cylindrical castings, pipe sleeves and the like with uniform wall thickness can be cast. The cylinder liner is generally produced by using a horizontal centrifugal casting machine.
However, most of the existing centrifugal casting machines need to be manually demoulded after casting is completed, the castings are in tight contact with the casting mould, workers generally knock the surface of the casting mould to separate the casting mould from the casting mould, and then the casting is pulled out of the casting mould by pliers, so that the demould process is time-consuming and labor-consuming, the casting temperature just poured is high, the workers are easy to scald in the process of pulling the casting out of the casting mould, and great potential safety hazards exist.
