[0044] The working principle of this embodiment is as follows: (1) Feeding: the molten plastic flows into the feed barrel 402 through the feed hopper 404, the heater 403 heats the molten plastic to ensure that the molten plastic reaches an appropriate melting temperature, the output shaft of the motor 405 drives the spiral roller 407 to rotate, and the spiral roller 407 transports the molten plastic in the feed barrel 402 to the inside of the feed shell 401 through the first feed port 408 of the feed shell 401, and the molten plastic in the feed shell 401 enters the connecting shell 411 through the first discharge port 409 and the second feed port 412 in turn. Since the friction wheel 503 on the connecting rod 504 conflicts with the friction plate 406, the second discharge port 414 at the bottom of the connecting shell 411 is connected to the injection hole 515 of the upper mold 501, and the molten plastic in the connecting shell 411 enters the injection molding mechanism through the injection hole 515.

[0045] (2) Injection molding: The upper mold 501 located at the top is connected to the first lower mold 502, the second lower mold 505 and the third lower mold 506 located at the bottom. The first cavity 512 of the upper mold 501, the first mold core 507 and the gap between the second mold core 508 and the second cavity 513 form an injection molding space. The molten plastic in the connecting shell 411 enters the injection molding space through the injection hole 515 for injection molding. The first cavity 512 can be used to injection mold the sole of the anti-static shoe 7. The gap between the first mold core 507 and the second mold core 508 and the second cavity 513 can be used to injection mold the upper of the anti-static shoe 7. After the molten plastic fills the injection molding space, the plastic solidifies after cooling to form the anti-static shoe 7.

[0046] (3) Mold opening: the output end of the second electric cylinder 605 drives the second lower mold 505 to move in the horizontal direction, the third guide rod 604 on the second lower mold 505 moves in the horizontal direction on the third support plate 613, the second lower mold 505 moves to be separated from the anti-static shoe 7, the output end of the third electric cylinder 606 drives the third lower mold 506 to move in the horizontal direction, the fourth guide rod 607 on the third lower mold 506 moves in the horizontal direction on the fourth support plate 614, and the third lower mold 506 moves to be separated from the anti-static shoe 7.

[0047] The output end of the first electric cylinder 601 drives the first lower mold 502 to move in the vertical direction, and the first lower mold 502 drives multiple second guide rods 602 to slide in the vertical direction on the lower box 3. The first lower mold 502 is separated from the upper mold 501. The first lower mold 502 drives the first mold core 507, the second mold core 508 and the anti-static shoe 7 to move in the vertical direction. The resistance wheel 503 on one side of the first lower mold 502 is separated from the resistance plate 406. Under the action of the first spring 410, the resistance plate 406 drives the connecting shell 411 to slide horizontally on the first fixing rod 413, and the second feed port 412 of the connecting shell 411 moves to be separated from the first discharge port 409 of the feed shell 401, and the molten plastic no longer enters the connecting shell 411.

[0048] The second slide bars 611 on both sides of the first mold core 507 slide in the vertical direction into the inclined slide hole 612 of the second support plate 603. When the second slide bars 611 slide to the lowest point of the inclined slide hole 612, the first mold core 507 drives the second mold core 508 to move to separate from the second cavity 513 of the first lower mold 502. The first mold core 507 drives the first guide rod 610 and the first slide bar 608 to slide in the horizontal direction on the fifth support plate 615 at the bottom of the first lower mold 502. At the same time, the slider 514 on the second mold core 508 can slide on the second fixed rod 509 on the first mold core 507, so as to facilitate the demolding of the anti-static shoes 7.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
