Repeat the assembly steps to install according to usage requirements. When multiple molds are installed, the fixing tube 8 is inserted into the installation groove 17. At this time, the reaction force of the spring 7 drives the sliding plate 6 to rotate the rotating plate 9. Then, the rotation of the rotating plate 9 causes the locking block 11 to engage inside the installation groove 17, thus realizing the rapid installation of multiple molds. This achieves the effect of saving space and molten steel. By rotating the L-shaped plate 20, the clamping block 22 is positioned above the mold 2. Then, by rotating the knob 23, the screw 21 drives the clamping block 22 to abut against the mold 2, thus achieving the effect of quickly fixing the mold 1 and the mold 2. When disassembly is required, the screw 21 is rotated in the opposite direction to remove the clamping block 22. Then, by pulling the anti-slip sleeve 16, the connecting plate 14 drives the sliding plate 6 to compress the spring 7 to extend and retract, thereby driving the clamping block 11 to retract into the fixed tube 8, thus achieving the effect of quick disassembly.
