The processing mechanism 300 can drive the material picking mechanism 200 for use through the lifting cylinder 320.

[0034] When in use, the upper mold 290 is driven down by the processing mechanism 300 to engage with the lower mold 111. At the same time, the connecting rods 280 on both sides of the upper mold 290 drive the connecting column 270 to move. The connecting column 270 uses the fixed sleeve 250 to drive the moving rod 240 for adjustment. The moving rod 240 is adjusted through the rotating shaft and the fixed block 260 and the fixed rod 230. When the connecting column 270 descends, the fixed rod 230 will drive the connecting rod 220 and the bottom plate 210 to descend, so that the lower mold 111 can be sealed, and then injection molding is performed through the injection port 291 to process the workpiece. On the contrary, after the processing is completed, the upper mold 290 will rise and drive the bottom plate 210 to rise, so as to lift the processed workpiece, so that the workpiece can be directly taken out, which is convenient for the staff to operate, and there will be no situation where the processed workpiece may be damaged during removal.
