Problems solved by technology

[0004] However, when preparing parts with complex structures, especially parts with complex internal structures, such as pump bodies, cylinder blocks, etc., the traditional casting process has a very low yield rate when casting these complex parts, especially for some internal parts. For parts with curved pipes and thin-walled structures, it is often impossible to cast good-quality parts using traditional casting processes

Abstract

The invention relates to centrifugal type pressurizing casting equipment and a method thereof. The centrifugal type pressurizing casting equipment comprises a circular rotary disk driven to rotate through a motor. A sandbox containing a sand mold is fixed to the rotary disk. The circumferential sides of the sandbox are all provided with fixing blocks used for fixing the sandbox. A circular cover plate used for covering the sandbox is arranged above the rotary disk. The center of the upper surface of the cover plate is provided with a through hole. The through hole rightly corresponds to a grouting hole of the sand mold in the sandbox. A grouting pipe is arranged above the through hole. According to the equipment, not only can common parts be cast, but also parts of complex structures can further be cast.

Description

technical field [0001] The invention relates to a centrifugal pressurized casting equipment and a method thereof. Background technique [0002] Casting - smelting metal, making casting molds, pouring molten metal into casting molds, and obtaining metal parts blanks with certain shape, size and performance after solidification [0003] Casting is the process of smelting metal into a liquid that meets certain requirements and pouring it into a mold, cooling and solidifying, and cleaning to obtain a casting with a predetermined shape, size and performance. Because the casting blank is almost formed, the purpose of free machining or a small amount of machining reduces the cost and reduces the production time to a certain extent. Casting is one of the basic processes of modern device manufacturing industry. [0004] However, when preparing parts with complex structures, especially parts with complex internal structures, such as pump bodies, cylinder blocks, etc., the traditiona...
