[0002] Manufacturing and other related industries often need to replace various molds and transport them during the production process. In this process, they will encounter problems such as inconvenient loading and unloading of molds, high labor intensity, and small space when using forklifts. For example, when installing molds during the production process, a conventional stacker is generally used to fork the mold from the mold rack to the machine tool table, and then the mold is dragged to the middle of the machine with a crane. In this process, two tool stackers and cranes are required. On the one hand, changing tools prolongs the mold installation time, and on the other hand, using a crane to pull the mold poses a safety hazard. This results in increased labor intensity for operators, low work efficiency, and long mold installation time. The operational safety risk is relatively high and cannot meet the needs of production.

[0022] When in use, the stacker is pushed to the side of the mold to be transported, and the brushless motor 34 is started according to the width of the mold to drive the bidirectional screw rod 40 to rotate, thereby adjusting the width between the two fork arm assemblies 2. Then the stacker is adjusted, the fork arm assembly 2 is inserted into the bottom of the mold, and the suction cup magnet 29 firmly absorbs the mold. The stacker is adjusted to the front of the working platform, and the lifting cylinder 61 is started. The cylinder rod rises, and the lifting chain 63 is lifted upward through the lifting sprocket 62, thereby driving the lifting frame assembly 3 and the fork arm assembly 2 to move upward. When the lifting frame assembly 3 and the fork arm assembly 2 are moved to be parallel to the working platform, the lifting cylinder 61 stops working. Put the external mold lifter 72 into the slot of the workbench, start the switches of the two sets of mold lifters, and the two sets of mold lifters will be lifted up synchronously. At this time, another brushless motor 34 will work, driving the main tooth sprocket 24 to rotate through the spline shaft 41, thereby driving the auxiliary tooth sprocket 25 to rotate through the vertical fork arm chain 26, and then driving the suction cup magnet 29 on the horizontal fork arm chain 26 to move together with the mold. The limit block in the magnet fixing block 28 hits the micro switch 30, the suction cup magnet 29 is powered off to release the mold, and the brushless motor 34 stops working. Then press the switches of the two sets of mold lifters, the two sets of mold lifters descend at the same time, the mold falls on the workbench, the external mold lifter 72 is pulled out, and then the stacker withdraws, and the mold loading is completed. The same is true for unloading the mold.
