Background technique

In foundry production, sand casting is a commonly used method, in which the mold is one of the important tools for casting molding. Usually, the button mold and inserts are set in the clay wet sand mold to cooperate with each other to realize the different shapes of the casting.

When the existing mold is in use, the shape of the casting is controlled by placing clay wet sand molds in the upper and lower molds. During casting, the molten metal is poured through the casting port reserved for the clay wet sand mold in the upper mold, but during casting, the molten metal There may be bubbles at the position in contact with the clay wet sand mold, and the bubbles are present in the clay wet sand mold. The operator cannot observe in time. The bubbles generated after the production will form pores after the casting is cooled and formed. Then the production quality of the device is reduced.

The existing mold needs to take out the casting from the clay green sand mold after the casting is cooled and formed. The clay wet sand mold affects the production of the subsequent process, and the operator needs to use tools to remove the residual clay wet sand mold on the casting. The operation is complicated and increases the labor intensity of the operator.

Before the existing mold is produced, the upper mold needs to be turned over, and the upper and lower molds need to be transported. When turning the upper mold and transporting the upper and lower molds, a small amount of clay wet sand mold may fall off, and the clay that falls off from the upper mold The green sand mold may enter the casting position of the lower mold, and when the molten metal is poured, the released clay wet sand mold may affect the shape of the casting, which may cause the casting to be scrapped and increase the production cost of the device.
