[0025] Specifically, such as Figure 1 and Figure 2 As shown, when the drive motor 16 is turned on, the drive screw 17 rotates, which can move the external second connecting block 22. At this time, the first connecting blocks 20 on both sides of the top of the fixed tube 18 will move outside the fixed rod 21, and the cooling water will be injected into the fixed tube 18 through the external pipe 23. Finally, the sand mold at the bottom can be sprayed and cooled through the equally spaced diversion spray holes 19 at the bottom, which makes it convenient to cool and form quickly.
[0026] Support rods 7 are fixedly connected to the four corners at the top of the base 1, and the four corners of the fixing plate 14 are slidably fitted onto the outside of the support rods 7.
