[0004] In order to overcome the above technical problems, the purpose of the present utility model is to provide a rapid mold replacement mechanism. When two U-shaped frames are about to approach each other, two second square rods will respectively contact both ends of the first slider. The second square rods are squeezed, which will drive the two molds to gather towards the middle until they are close together, effectively improving the sealing performance and working stability. By the extrusion of two opposing inclined blocks by the second slider, the inclined blocks slide outwards from the third square groove and closely adhere to the outer wall of one side of the mold to limit the mold. Combined with the adsorption of the second electromagnet, the fixing of the mold is effectively improved.
