Problems solved by technology

[0002] Engine cylinder liners are generally manufactured by centrifugal casting technology. The centrifugal casting equipment in the prior art is generally a fixed runner, that is, the casting liquid flows into the mold from a fixed position, which makes the distribution of the casting liquid in the mold uneven and prolongs the molding cycle. Moreover, the cylinder liner is prone to local internal stress, which affects the forming quality of the cylinder liner

Embodiment Construction

[0024] In order to make the objects and advantages of the present invention clearer, the present invention will be specifically described below in conjunction with examples. It should be understood that the following words are only used to describe one or several specific implementation modes of the present invention, and do not strictly limit the protection scope of the specific claims of the present invention.

[0025] Such as Figure 1-4 As shown, a cylinder liner centrifugal casting system includes a casting unit and a centrifugal unit. The centrifugal unit includes a cylindrical mold body 10 rotatably arranged along a horizontal axis. The first end of the cylindrical mold body 10 is provided with a first end plate 11. The second end of the cylindrical mold body 10 is provided with a second end plate 12, and the center of the second end plate 12 is provided with a casting channel, and the casting unit is located outside the casting channel, and the casting unit is used for...

Abstract

The invention belongs to the technical field of casting and processing of auto parts, and specifically relates to a centrifugal casting sprue, which includes a bowl-shaped material receiving trough and a fixed flow channel connected to the bowl-shaped material receiving trough, and a rotating body is sleeved on the fixed flow channel , the rotating body is arranged to rotate along a rotating shaft parallel to the length direction of the fixed flow channel, and a movable flow channel is opened on the rotating body, and the movable flow channel penetrates from the inner ring surface of the rotating body to the outer ring surface of the rotating body, The movable channels are arranged in a spiral shape. The movable runner of the invention can make the drop point of the casting liquid in the mold change linearly along the axial direction of the mold, ensure rapid and uniform distribution of the casting liquid, shorten the casting time, and avoid local accumulation of the casting liquid to affect the quality of the casting.

Description

technical field [0001] The invention belongs to the technical field of casting and processing of auto parts, and in particular relates to a centrifugal casting runner and a centrifugal casting system. Background technique [0002] Engine cylinder liners are generally manufactured by centrifugal casting technology. The centrifugal casting equipment in the prior art is generally a fixed runner, that is, the casting liquid flows into the mold from a fixed position, which makes the distribution of the casting liquid in the mold uneven and prolongs the molding cycle. Moreover, the cylinder liner is prone to local internal stress, which affects the forming quality of the cylinder liner. Contents of the invention [0003] The object of the present invention is to provide a centrifugal casting sprue and a centrifugal casting system capable of rapidly and uniformly distributing the casting liquid. [0004] The technical scheme that the present invention takes is specifically as fo...
