Abstract

The invention discloses a centrifugal casting device and relates to the technical field of centrifugal casting equipment. The device comprises a supporting mechanism, a molding mechanism and a pouringmechanism; the molding mechanism comprises a first rotating shaft rotationally connected with a second vertical plate; the first rotating shaft and a through hole are coaxially formed; one end, closeto a first vertical plate, of the first rotating shaft is coaxially and fixedly connected with a first-end cam; the pouring mechanism comprises a second rotating shaft coaxial with the first rotatingshaft; the second rotating shaft is located on one side, close to the first vertical plate, of the first rotating shaft; a cylindrical blind hole in sliding fit with the second rotating shaft is formed in the first rotating shaft; a second-end cam in clutched fit with the first-end cam is fixedly connected onto the first rotating shaft; and a pouring pipe is arranged between the first rotating shaft and the first vertical plate. The first rotating shaft rotates to drive the pouring pipe to rotate, so that the speed difference between a metal liquid and a mold is reduced, then scouring of themetal liquid on a molding sand layer is reduced, and the problem of relatively short service life of molds in the prior art is solved.

Description

Technical field [0001] The invention relates to the technical field of centrifugal casting equipment. Background technique [0002] Centrifugal casting is to inject molten metal liquid into a high-speed rotating mold, and the metal liquid completes the filling under the action of centrifugal force. Centrifugal casting is widely used in the casting of cylindrical pipe fittings. In the existing centrifugal casting mold, molding sand is used to make the molding cavity of the mold, so as to facilitate the production of workpieces of different sizes. When casting, the mold rotates at a high speed, and then the metal liquid is injected into the mold by the flow guide tube, and the metal liquid forms a workpiece under the action of centrifugal force. However, due to the high-speed rotation of the mold, the metal liquid flows out of the draft tube at a low speed, which results in a large speed difference between the metal liquid and the mold, so that the metal liquid affects the sand l...
