[0004] With regard to the above-mentioned related technologies, the die-casting machine in the current prior art is usually in the above-mentioned form when in use. The two molds are closed and then the solution is injected between the two molds to form.

When this situation occurs, the mold needs to be switched, otherwise the mold will affect the quality of the subsequent parts. In the prior art, the disassembly and replacement of the mold is relatively complicated, and the overall disassembly and installation method is not convenient for the staff to operate quickly, resulting in a long time spent in the replacement state, and the whole machine body needs to be shut down for replacement, which seriously affects the normal operation of the machine, and thus makes the machine fault tolerance rate not high.

The incomplete gear 332 will first drive the connecting gear 328 to rotate 180 degrees, and the connecting gear 328 will drive the reciprocating roller 326 to rotate, and the reciprocating roller 326 will pass The reciprocating groove 327 pushes the sliding shaft 324 and the long plate 323, and the long plate 323 will drive the injection device 321 to slide inside the displacement groove 340, so that the sleeve tube 322 withdraws from the sealing groove 280 and separates from the connecting tube 270, and then the incomplete bevel gear 333 drives the small bevel gear 316, and the small bevel gear 316 will drive the large transmission roller 315 to rotate multiple circles, so that the large transmission roller 315 accelerates the transmission of the small transmission roller 313 through the transmission belt 317, and the small transmission roller 313 will drive the threaded rod 312 to rotate, and the threaded rod 312 will drive the second U-shaped frame plate 130 to displace, so that the four balls 233 will be removed from the isosceles trapezoidal block 170, and at the same time, the movable block 232 is lifted up by the first spring 235, so that the balls 233 rolls close to the track plate 160, at which time the plug rod 234 will withdraw from the metal clamping block 231, and the four movable plug-in components 230 will unlock the first mold 240 and the second mold 250 at the same time. The staff can push the first mold 240 and the second mold 250 outward, so as to push the metal clamping block 231 out of the slot 237 and separate it from the magnetic block 236, and the first mold 240 and the second mold 250 can be quickly removed and replaced. At the same time, the four balls 233 of another switching molding module 200 will move to the position of the four isosceles trapezoidal blocks 170, so that the balls 233 drive the plug rod 234 to descend to lock the other first mold 240 and the second mold 250, which is convenient for subsequent processing.At this time, the connecting slider 150 will slide into between the two C-shaped limit rails 260 of another switching molding module 200, so that the cylinder 140 can push the other first mold 240 to work, and finally the incomplete gear 332 will drive the connecting gear 328 again, so that the injection device 321 drives the sleeve tube 322 to reset, so that it can be docked with the other connecting tube 270 and the sealing groove 280, so that the two switching molding modules 200 can be quickly switched and replaced. When the existing first mold 240 and the second mold 250 have problems again, the drive motor 331 can be turned on in reverse to achieve reverse drive, so that the re-placed first mold 240 and the second mold 250 can be locked again for use, thereby making the fault tolerance rate of the device higher. When problems occur in the first mold 240 and the second mold 250, the switching and replacement can be fast, and the normal operation of the equipment will not be affected as much as possible.
