[0005] The purpose of the utility model is achieved through the following technical scheme: an adjustable size sand mold outer mold, including a fixed mold, a slidable movable mold is installed on the fixed mold, the inner cavity of the fixed mold is connected to the inner cavity of the movable mold, a slide groove is opened in the fixed mold, and the movable mold is slidably connected to the slide groove.
[0006] A further technical solution is that a sliding block is installed on the bottom surface of the movable mold, and the sliding block is slidably connected with the sliding groove.
[0007] A further technical solution is that two groups of discharge holes are opened on the bottom surface of the slideway, the discharge holes are respectively located at two ends of the slideway, and a detachable first sealing block is installed in the discharge hole.
[0008] A further technical solution is that the fixed mold is provided with through holes in an equidistant array, the movable mold is provided with fixing grooves matched with the through holes, and fixing pins are inserted between the through holes and the fixing grooves.
[0009] A further technical solution is that a detachable second sealing block is installed on the upper part of the through hole.
[0010] A further technical solution is that a handle is installed on the side of the movable mold away from the fixed mold.
[0011] The utility model has the following advantages: the utility model can adjust the size of the cavity between the fixed mold and the movable mold by arranging the fixed mold and the movable mold to cooperate with each other, so that the fixed mold and the movable mold can produce products of different sizes, which not only occupies a small space but also saves costs; the discharge hole opened on the bottom surface of the slide groove can enable the slider to discharge the loose sand in the slide groove during the movement, thereby preventing the loose sand from affecting the sliding between the fixed mold and the movable mold; the fixed pin can be set to fix the position of the fixed mold and the movable mold, thereby improving the stability of the connection between the fixed mold and the movable mold.
