It integrates advanced technologies in multiple fields such as mechanics, electronics, and materials, and has a complex and sophisticated structure. Many parts in a car are made of aluminum. When producing such parts, die-casting equipment is usually required to die-cast them.

[0004] With regard to the above-mentioned related technologies, the die-casting machine in the existing technology is usually in the above-mentioned form when in use. The two molds are closed and the solution is injected between the two molds to form the mold. However, during the die-casting process, the mold has to withstand high temperature and high pressure of the molten metal, which is prone to wear and cracking. At the same time, thermal fatigue may also exist. Frequent hot and cold states may easily cause fine cracks on the surface of the mold. When this situation occurs, the mold needs to be switched, otherwise the mold will affect the quality of the subsequent parts. In the existing technology, 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.

When cracks appear in the first mold 240 and the second mold 250, affecting the casting quality, the staff turns on the drive motor 331 to drive the incomplete gear 332 and the incomplete bevel gear 333 to rotate. 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323 will drive the injection device 321 to slide inside the displacement groove 340, so that the sleeve tube 322 is withdrawn from the sealing groove 280 and separated from the connecting tube 270. 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 times, 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 insertion rod 234 will withdraw 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 to push the metal clamping block 231 out of the slot 237 and separate it from the magnetic block 236, so that 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 insertion rod 234 to descend and 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 the space between the two C-shaped limit rails 260 of the other switching molding module 200, so that the cylinder 140 can push the other first mold 240 to work. Finally, the incomplete gear 332 transmits the connecting gear 328 again, so that the injection device 321 drives the sleeve tube 322 to reset, so that it completes the docking 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 the reverse direction 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. If 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.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
