Abstract

This utility model relates to the field of casting process technology and discloses an automatic mold shell clamping and sand tray exchange system after casting. It includes: a mold shell unloading trolley, set on an unloading track, for carrying the cast mold shell; an automatic clamping mechanism, including a clamping frame, cylinder, sliding sleeve, sliding rod, lifting plate, clamping cylinder, and clamp, wherein the cylinder drives the lifting plate to move vertically through the sliding sleeve and sliding rod, and the clamping cylinder is connected to the clamp for clamping and clamping the insulation box to the mold shell; and a sand tray exchange system, including a first sand tray exchange track, a second sand tray exchange track, a chain drive, and a transfer sand tray for carrying full and empty sand trays. The first and second sand tray exchange tracks achieve automatic exchange between full and empty sand trays via the chain drive. The mold shell unloading trolley, automatic clamping mechanism, and sand tray exchange system work together to achieve automated processing of the cast mold shell.
