The invention belongs to the technical field of centrifugal
casting and particularly relates to a
casting mold structure and a base plate applicable to medium and large-scale vertical centrifugal
casting machines. The
casting mold structure and the base plate comprise baseboards, cover plates and
metal sleeves. The baseboards have N models, a
baseboard of each model corresponds to one cover plate of one model and a
metal sleeve of one model, and the outer diameters of the baseboards, the cover plates and the
metal sleeves of the same models are the same. The outer diameters of the baseboards of different models are different. Pressing plates have P models, and a pressing plate of each model corresponds to 1-2 cover plates of adjacent models. When an annular pressing plate of one model corresponds to two cover plates of adjacent models, annular outer
radius of the pressing plate>=outer
radius as 30mm of the cover plate of a corresponding larger model, and the inner
radius of the pressing plate>=a pouring port step position outer end size as 30mm of the cover plate of a corresponding smaller model. The
casting mold structure and the base plate have the advantages of forming a series of baseboards, cover plates and metal sleeves, enabling repeat use rate of the baseboards and the cover plates to be high, enabling the comprehensive cost price of a
casting mold to be reduced, and simultaneously reducing production preparation periods.
