Description

Technical Field

[0001] The present application relates to the technical field of centrifugal liner production equipment, and in particular to a mold for producing centrifugal liner. Background Art

[0002] Centrifugal casting is a casting method in which liquid metal is poured into a rotating mold, so that the liquid metal fills the mold and solidifies under the action of centrifugal force. To achieve the above process, a centrifugal casting machine must be used to create conditions for the mold to rotate. Steel balls and cast balls are commonly made by vertical centrifugal casting machines according to the different spatial positions of the rotating axis of the mold. At the same time, a liner is generally installed inside the centrifugal casting machine to protect the inside of the cylinder from impact and friction. The production and processing of the liner in the prior art requires the use of a liner mold, and the space for the liner is formed by the closure between the upper mold and the lower mold, which is injection molded into the liner.

[0003] At present, a Chinese patent announcement with announcement number CN220428990U discloses a ball mill liner production mold. The application proposes that "after the mold is injected and the internal liner is cooled, the formed liner will fall into the lower mold, and the lower mold needs to be removed from the operating table for demoulding, which will not affect the production of the next liner. Furthermore, when removing the lower mold, auxiliary tools are needed, which makes the operation more preventive and time-consuming, thereby affecting the operator's work efficiency."
