[0025] The ejector pins are placed into the ejector pin box 14 in sequence, so that the ejector pins are arranged horizontally in sequence from top to bottom. Then, the cylinder 7 is started to push the ejector pin at the bottom of the ejector pin box 14 to move. During this process, the sliding groove 22 on the output shaft of the cylinder 7 slides relative to the movable plate 8. When sliding to the end of the sliding groove 22, the sliding groove 22 pushes the movable plate 8 to move.

By cycling the above process, the batch grinding operation of ejector pins can be automatically completed, which is convenient and quick to use, and solves the problem that the existing ejector pin grinding device needs to manually fix the ejector pin on the fixture and then grind it. After each pin is ground, the fixing and disassembly process needs to be repeated, which is time-consuming and labor-intensive, and reduces the work efficiency.

[0026] Specific usage and function of this embodiment: The utility model puts the ejector pins into the ejector pin box 14 in sequence, so that the ejector pins are arranged horizontally in sequence from top to bottom. Then, the cylinder 7 is started to push the ejector pin at the bottom of the ejector pin box 14 to move. During this process, the sliding groove 22 on the output shaft of the cylinder 7 slides relative to the movable plate 8. When sliding to the end of the sliding groove 22, the sliding groove 22 pushes the movable plate 8 to move. The movable plate 8 pushes the guide rail 10 and the sliding block 11 to move through the connecting frame 9. The first sliding block 12 on the sliding block 11 moves along the first sliding groove 5 on the first connecting plate 4. When the first sliding block 12 moves from the inclined section of the first sliding groove 5 into the horizontal section, the first sliding block 12 drives the sliding block 11 and the clamping block 13 to move toward the ejector rod, thereby clamping the needle rod. Then , the grinding operation is performed through the grinding machine body 1. When the grinding is completed, the output shaft of the cylinder 7 moves back, so that the output shaft drives the guide rail 10 and the sliding block 11 to move back through the movable plate 8 and the connecting frame 9, so that the first slider 12 on the sliding block 11 enters the inclined section from the horizontal section of the first slide groove 5, and the two clamping blocks 13 are separated from the needle bar. At the same time, the connecting frame 9 drives the second connecting plate 17 to move back through the second connecting rod 16, so that the second slider 19 on the push plate 20 slides along the second slide groove 18 on the second connecting plate 17 and moves from the horizontal section to the inclined section, so that the second slider 19 pushes the push plate 20 to move along the guide rod 21 to eject the ground ejector pins.
