AI Technical Summary

Technical Problem

In the casting process of large-diameter cylinder liners, problems such as excessively tight or loose mold closing leading to gaps can result in poor casting quality.

Method used

The system employs a combination of a base platform, lower mold, vertical groove plate, horizontal width plate, electric hydraulic rod, convex template, U-shaped frame, round tube, U-shaped slide plate, and curved rod. The movement of the slide plate is restricted by the limit frame to prevent the mold from closing too tightly or leaving gaps. Combined with a cooling device and a deceleration device, it achieves rapid cooling and buffered movement to avoid mold damage and scalding from spillage.

Benefits of technology

It effectively prevents casting quality problems caused by poor mold closing, improves casting efficiency, ensures mold safety, and avoids mold damage and worker burns.

Abstract

The application discloses a metal mold for casting a large-bore cylinder liner, and relates to the technical field of casting metal molds.The metal mold comprises a bottom base, a lower mold fixed to the top surface of the bottom base, two vertical groove plates arranged on the top surface of the bottom base, a sliding groove arranged in the middle of the side of the two vertical groove plates that are close to each other, a horizontal width plate fixed to the top surface of the two vertical groove plates, a plurality of electric hydraulic rods penetrating through and fixed to the top surface of the horizontal width plate, a male die plate fixed to the bottom surface of the telescopic end of each electric hydraulic rod, an exhaust pipe penetrating through and fixed to the top surface of the male die plate, and a back-shaped sliding plate contacting the top of a limiting frame during downward movement, wherein the limiting frame is arranged below the back-shaped sliding plate and limits the downward movement distance of the back-shaped sliding plate, so that the problem of poor quality of the metal mold for casting the large-bore cylinder liner caused by over-tightening or gaps of the mold is avoided.
