[0058] like Figures 1-14As shown, the master cylinder piston body 01 is transported by a conveyor belt 1 and is grabbed by a pickup mechanism 3 provided on the conveyor belt 1. The grabbed master cylinder piston body 01 is moved to the edge of the assembly processing mechanism 4, where it cooperates with the upper mold 48 and lower mold 47 placed on the rotating disk 44. The rubber ring 03 is injected between the upper mold 48 and lower mold 47 in conjunction with the injection tube 410 and the barrel. After solidification, the rubber ring 03 is directly engaged with the groove 02 at the end of the master cylinder piston. This eliminates the need for manual assembly of the rubber ring 03 with the groove 02 at the end of the master cylinder piston body 01, improves the fit between the rubber ring 03 and the end of the master cylinder piston body 01, and enhances the sealing effect. The telescopic cylinder 360 in the grabbing assembly 36 drives the moving disk 362 to move horizontally, controlling the annularly distributed mating rods 363 and the contact blocks 364 at the ends to expand within the inner ring of the master cylinder piston body 01, thereby achieving the grabbing of the master cylinder piston body 01. The horizontal cylinder 1 33 and the vertical cylinder 1 35 drive the grabbing assembly 36 and the master cylinder piston body 01 to move to the edge of the combined processing mechanism 4, thereby injecting the rubber ring 03 on the edge of the master cylinder piston body 01. The telescopic cylinder 2 46 controls the upper mold 48 and the lower mold 47 to move along the radius of the rotating disk 44, so that the upper mold 48 and the lower mold 47 can cooperate with the end of the master cylinder piston body 01 extracted by the extraction mechanism 3. After the injection molding is completed, the extraction mechanism 3 releases the grip on the master cylinder piston body 01, and the rotating disk 44 combines with the upper mold 48 and the lower mold 47 to index the master cylinder piston body 01, thereby performing the injection molding operation of the next master cylinder piston body 01 and simultaneously performing the unloading operation on the master cylinder piston body 01 that has completed the injection molding operation. To facilitate the complete separation of the master cylinder piston body 01 and rubber ring 03 from between the upper mold 48 and lower mold 47 after injection molding, a release agent cartridge 414 and a mating head 415 interact with the upper and lower molds 48 and 47 before injection molding. The mating head 415, in conjunction with the release agent, sprays the release agent between the upper and lower molds 48 and 47. The upper and lower molds 48 and 47 are controlled by a telescopic cylinder 3 and the mating head 415. After injection molding and high-temperature vulcanization, the rubber ring 03 is transferred to the unloading mechanism 5. The gripping assembly 36 on the lifting frame 2 54 grasps the end of the master cylinder piston body 01. After the master cylinder piston body 01 and the rubber stopper are completely separated from the upper and lower molds 48 and 47, the telescopic motor 3 56 and the arc-shaped pressure plate 2 57 compress the master cylinder piston body 01. The retractable cutter 59 on the fixed plate 58 removes the injection gate.
