The outer surface of mounting block 904 is set up with mounting hole. The inside rotation of mounting hole is connected with rotating shaft 905. One end of rotating shaft 905 is installed with first gear 906 in cooperation. First gear 906 is engaged with first rack 903 and is connected;

[0027] In use, first, the feed pipe is installed with the feed end of the upper mold 8, after installation, by starting the hydraulic cylinder 5, the output end of the hydraulic cylinder 5 drives the connecting frame 6 to move to the lower end, and then the upper mold 8 and the lower mold 11 are closed, when the upper mold 8 and the lower mold 11 are closed, by operating the control valve of the feed pipe, the injection material enters the forming cavity of the lower mold 11 through the feed end of the upper mold 8, and the injection of the workpiece is carried out;

[0028] The outer surface of the moving plate 7 is provided with a rectangular block 907, the lower surface of the rectangular block 907 is provided with a sliding groove 908, the first sliding block 909 is slidably connected in the sliding groove 908, the lower surface of the first sliding block 909 is provided with a connecting block 9011, the lower end of the connecting block 9011 penetrates through the anti-dropping block 9010 and is provided with a second rack 9012, the other end of the rotating shaft 905 is provided with a second gear 9013, and the second gear 9013 is in meshing connection with the second rack 9012.

[0029] The size of the second rack 9012 is consistent with that of the first rack 903, and the size of the second gear 9013 is consistent with that of the first gear 906.

[0030] When the injection of the workpiece is completed, the output end of the hydraulic cylinder 5 is reset, and then the connecting frame 6 drives the moving plate 7 to move to the upper end, so that the upper mold 8 and the lower mold 11 are separated, when the moving plate 7 moves upward, the rectangular block 907 moves to the upper end, and the first sliding block 909 remains stationary in the sliding groove 908, when the moving plate 7 moves to a certain height, the lower surface of the first sliding block 909 abuts against the upper surface of the anti-dropping block 9010, when the moving plate 7 moves upward, the anti-dropping block 9010 drives the first sliding block 909 to move upward, and then the first sliding block 909 drives the second rack 9012 to move upward through the connecting block 9011, because the second rack 9012 is in meshing connection with the second gear 9013, when the second rack 9012 moves upward, the second gear 9013 rotates, when the second gear 9013 rotates, the first gear 906 rotates synchronously through the rotating shaft 905, because the first gear 906 is in meshing connection with the first rack 903, when the first gear 906 rotates, the first rack 903 can move vertically, so that the first rack 903 drives the connecting plate 902 to move upward, so that the ejector rod 901 slides upward in the through hole, and then the ejector rod 901 can eject the formed workpiece from the inside of the forming cavity, so that manual demolding of the workpiece is not needed, and good practical effect is achieved.

[0031] When the upper die 8 and the lower die 11 are closed again, the output end of the hydraulic cylinder 5 drives the connecting frame 6 to move downward, and then the moving plate 7 drives the rectangular block 907 to move downward, so that the anti-dropping block 9010 and the first sliding block 909 are disengaged. When the moving plate 7 is lowered to a certain height, the surface of the first sliding block 909 abuts against the inner surface of the sliding groove 908. When the moving plate 7 is further lowered, the rectangular block 907 pushes the connecting block 9011 and the second rack 9012 downward through the first sliding block 909. Since the second rack 9012 is engaged with the second gear 9013, the second rack 9012 is moved downward, which drives the second gear 9013 to rotate. When the second gear 9013 rotates, the first gear 906 is synchronously rotated through the rotating shaft 905. Since the first gear 906 is engaged with the first rack 903, the first gear 906 rotates, which drives the first rack 903 to move vertically, so that the first rack 903 pushes the connecting plate 902 to move downward, and then the ejector rod 901 is retracted into the through hole.

[0032] The lower surface of the second rack 9012 is provided with a baffle 9014.

[0033] The baffle 9014 can limit the movement of the second rack 9012 to prevent the second rack 9012 from being separated from the second gear 9013.

[0034] The upper surface of the bottom plate 10 is further provided with a guide rod 12, and the outer surface of the guide rod 12 is slidably connected with the moving plate 7 and the second sliding block 13. The upper surface of the second sliding block 13 abuts against the lower surface of the moving plate 7.

[0035] The outer surface of the guide rod 12 is sleeved with a buffer spring 14. One end of the buffer spring 14 is installed on the lower surface of the second sliding block 13, and the other end of the buffer spring 14 is installed on the upper surface of the bottom plate 10.

[0036] When the moving plate 7 moves downward on the guide rod 12, the second sliding block 13 moves downward along the axial direction on the guide rod 12 and gradually compresses the buffer spring 14. During the compression process of the buffer spring 14, the buffer spring 14 can buffer the downward force, thereby avoiding the problem of large instantaneous impact force when the upper die 8 and the lower die 11 are closed, and prolonging the service life of the upper die 8 and the lower die 11.

[0037] The lower surface of the upper die 8 is provided with a limiting rod 801, and the upper surface of the lower die 11 is provided with a limiting groove. The limiting rod 801 is installed in the limiting groove.

[0038] The limiting rod 801 and the limiting groove can be used in cooperation to position the upper die 8 and the lower die 11, thereby avoiding the positional deviation of the upper die 8 and the lower die 11 when they are closed.
