As modern mold manufacturing technology develops towards accelerating information-driven, improving manufacturing flexibility, agile manufacturing and systematic integration, casting molds need to use special tooling to assist in the operation of the molds when casting metal molds. After the metal casting is completed, the upper and lower ends of the mold need to be separated by special tooling to remove the formed metal workpiece. The existing device is not convenient for installing and limiting the lower molds of different sizes for casting, and it is not convenient to move the device.

[0003] The patent with application number 202320798213.8 discloses a special tooling for casting molds, which relates to the field of casting technology, and includes: an operating table, a top of which is provided with fixing bolts, a bracket, which is arranged under the operating table by bolts, and a support leg is connected to the bottom of the bracket by bolts, and a universal wheel is fixedly installed at the bottom end of the support leg, and a brake pad is provided on the surface of the universal wheel, a base, which is arranged above the operating table by bolts, and the base is connected to a tooling frame by bolts, and a limiting mechanism is installed on the tooling frame, and multiple groups of cooling grooves are opened at the bottom end of the tooling frame, and a fixing mechanism is set at the right end of the tooling frame, and a connecting mechanism is set between the tooling frame and the fixing mechanism, and a groove is opened on the right end of the tooling frame and the left upper surface of the fixing mechanism, and a protrusion is movably installed inside the groove, and threaded rods are connected on both sides of the tooling frame by bolts.
