Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of casting molds, and particularly relates to a mold for a buckle mold casting. BACKGROUND

[0002] In casting production, sand casting is a commonly used means, and a mold is one of important tools for forming a casting, and the mutual cooperation of a buckle mold and an insert is usually arranged in a clay wet sand mold to realize different shapes of the casting.

[0003] In use of the existing mold, the shape of the casting is controlled by placing the clay wet sand mold in the upper and lower molds, and the metal liquid is poured through the pouring opening reserved in the clay wet sand mold in the upper mold during pouring, but the position where the metal liquid contacts the clay wet sand mold may have bubbles, and the bubbles are present in the clay wet sand mold, and the operator cannot observe in time, and the bubbles generated after production ends form air holes after the casting is cooled and formed, thereby reducing the production quality of the device.

[0004] After the casting is cooled and formed, the existing mold needs to take out the casting from the clay wet sand mold, and the clay wet sand mold needs to be crushed during taking out, but a small amount of clay wet sand mold is still left on the surface of the casting after crushing, in order to avoid the influence of the remaining clay wet sand mold on the production of the subsequent process, the operator needs to use a tool to remove the remaining clay wet sand mold on the casting, and the operation is complex, and the labor intensity of the operator is increased.

[0005] Before production, the existing mold needs to turn over the upper mold, and needs to transport the upper and lower molds, and when the upper mold is turned over and the upper and lower molds are transported, a small amount of clay wet sand mold may fall off, and the clay wet sand mold falling off the upper mold may enter the pouring position of the lower mold, and when the metal liquid is poured, the clay wet sand mold falling off may affect the shape of the casting, and may cause the casting to be scrapped, thereby increasing the production cost of the device.
