Problems solved by technology

[0002] Engine cylinder liners are generally manufactured by centrifugal casting process. Existing centrifugal casting equipment needs to rely on a lot of manual operations, such as mold clamping, pouring, mold opening, demoulding and other processes. Manual operations are required, which is labor-intensive and low in production efficiency.

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 automobile part casting processing, and particularly relates to a demoulding device which comprises a cylindrical mold body which is rotationally arranged on a frame along a horizontal axis. The inner annular surface of the cylindrical mold body is conical, the diameter of a first end of an inner annular surface of the cylindrical mold body is smaller than that of a second end, a first end plate is arranged at the first end of the inner annular surface of the cylindrical mold body, a second end plate is arranged at the second end of the inner annular surface of the cylindrical mold body, each of the first end plate and the second end plate is of an annular structure, and the first end plate and the second end plate are in sliding fit with thecylindrical die body in the axial direction of the cylindrical die body; and a clamping claw capable of opening and closing in the radial direction of the cylindrical die body and moving in the axialdirection of the cylindrical die body is arranged in a central hole of the first end plate. The clamping claw can support the inner wall of a cylinder sleeve after the cylinder sleeve is formed, so that an inner coating of a mold is prevented from being damaged due to friction between the outer wall of the cylinder sleeve and the bottom surface of the inner wall of the cylindrical mold body during demoulding, and demoulding resistance is reduced.

Description

technical field [0001] The invention belongs to the technical field of casting and processing of auto parts, and in particular relates to a demoulding device. Background technique [0002] Engine cylinder liners are generally manufactured by centrifugal casting process. Existing centrifugal casting equipment needs to rely on a lot of manual operations, such as mold closing, pouring, mold opening, demoulding and other processes. Manual operations are required, which is labor-intensive and low in production efficiency. Contents of the invention [0003] The object of the present invention is to provide a demoulding device capable of realizing automatic demoulding of a centrifugal casting machine, so as to improve casting production efficiency. [0004] The technical scheme that the present invention takes is specifically as follows: [0005] A demoulding device, comprising a cylindrical mold body rotatably arranged on a frame along a horizontal axis, the inner ring surface ...
