[0042] Working principle process:

[0043] 1. Mold Assembly: First, the lower mold body 2 is secured to the lower bed 1, forming the foundation of the entire mold. The upper mold body 3 is placed above the lower mold body 2, and the two are precisely aligned through the cooperation of guide pins 208 and guide sleeves 302. The binder 4 is installed at the lower end of the upper mold body 3 to ensure that the workpiece is stabilized during the trimming process.

[0044] 2. Pre-positioning: The workpiece is pre-positioned on the lower die body 2 through the positioning plate 212 to ensure the consistency of the workpiece position during each processing and improve the processing accuracy.

[0045] 3. Pressing and fixing: The upper die body 3 is driven down by the press, and the pressing core 4 contacts the workpiece. Through the action of the spring guide pin 401 and the slide plate 402, the workpiece is fixed to prevent displacement during the processing.

[0046] 4. Trimming: The upper die body 3 continues to descend, and the upper die insert 303 cooperates with the lower die insert 211 to trim the workpiece and remove excess material.

[0047] After processing is complete, the drive cylinder 213 is activated, pushing the lifting plate 214 via the piston rod 215, which in turn drives the support rod 209, smoothly ejecting the workpiece from the mold. The rotational connection between the support rod 209 and the rotating bracket 210 ensures a smooth ejection process. The ejected workpiece slides directly out of the discharge rack 205, achieving automatic discharge without manual intervention. The cut waste automatically slides out of the mold via the waste slide 204, preventing waste accumulation, keeping the mold clean, and ensuring smooth subsequent processing.
