AI Technical Summary

Technical Problem

Due to the special appearance of the existing sand molds during flywheel shell manufacturing, it is easy to have adhesion problems when mold is opened, and hollowing or special burrs are easily present at the edge joints, which affects subsequent processing.

Method used

A cast aluminum mold suitable for flywheel shell manufacturing is designed, including a mold base, a load-bearing plate, a lower molding device, an upper molding device, a limit molding device and a feeding device. The mold realizes complete molding and rapid mold opening of the flywheel shell through structures such as lifting base, lower molding groove, butt guide column, upper mold forming block, positioning block and adjustment cylinder.

Benefits of technology

The mold can be used to process cast aluminum for the special shape of the flywheel shell, ensuring that the finished product is formed intact and burrless, achieving locking during processing, facilitating rapid mold opening and material extraction, and improving processing efficiency.

Abstract

The present invention discloses a cast aluminum mold suitable for manufacturing a flywheel shell, including a mold base, a bearing plate arranged on the mold base, a lower mold device arranged on the bearing plate, an upper mold device arranged on the lower mold device, a limiting molding device arranged around the upper mold device, and a feeding device arranged on one side of the upper mold device. In this way, the cast aluminum processing can be completed according to the special shape of the flywheel shell, ensuring that the finished product is completely formed without burrs. The upper mold device can cooperate with the limiting molding device to achieve locking during processing, and is convenient for rapid mold opening and material removal. An independent feeding device is provided, which can cooperate with conventional cast aluminum feeding equipment to meet effective feeding guidance and improve processing efficiency. It is equipped with a mold base, which can be locked and positioned with the base of various conventional mold processing equipment currently available. The overall structure is simple and easy to implement.
