Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] See Figures 1-5 In this embodiment of the utility model, a continuous injection mold includes a base 1, a fixed frame 16 is fixedly connected to the center of the base 1, a connecting tube 17 is fixedly connected to the fixed frame 16, a plurality of injection components are arranged on one side of the connecting tube 17 in a semi-circular distribution centered on the connecting tube 17, and a plurality of hot melt components are arranged on the other side of the connecting tube 17 in a semi-circular distribution centered on the connecting tube 17.

[0022] One end of the connecting tube 17 is fixedly connected to a first switching valve 18. A first rotary valve core 21 is rotatably installed inside the first switching valve 18. Multiple sets of connecting tubes 19 are fixedly connected to the first switching valve 18. An installation plug 20 is fixedly connected to the connecting tube 19. The installation plug 20 is connected to the injection molding assembly. A first servo motor 25 is installed on the control end of the first switching valve 18. The output shaft of the first servo motor 25 is fixedly connected to the first rotary valve core 21.

[0023] The other end of the connecting pipe 17 is fixedly connected to a second switching valve 22. A second rotary valve core 24 is rotatably installed inside the second switching valve 22. Multiple sets of sealing sockets 23 are fixedly connected to the second switching valve 22. The sealing sockets 23 are connected to the hot melt assembly. A second servo motor 26 is installed on the control end of the second switching valve 22. The output shaft of the second servo motor 26 is fixedly connected to the second rotary valve core 24.

[0024] This invention first melts and heats the raw material through the injection molding assembly. The molten and heated raw material enters the second conversion valve 22 through the sealing socket 23. At this time, this invention can control the second servo motor 26 to rotate precisely through the CNC center. The second servo motor 26 drives the second rotary valve core 24 to rotate, thereby replacing the hot melt assembly connected to the second rotary valve core 24, thus realizing the injection of different types of raw materials. At this time, the molten raw material enters the connecting material pipe 17 through the second rotary valve core 24, then enters the first conversion valve 18 through the first rotary valve core 21, and finally enters the injection molding assembly through the connecting pipe 19. Furthermore, this invention can also drive the first rotary valve core 21 to rotate through the first servo motor 25, thereby replacing the injection molding assembly connected to the first rotary valve core 21, thus realizing the sequential continuous injection of multiple sets of injection molds 5.

[0025] In one instance of this embodiment, please refer to Figures 1-5 The injection molding assembly includes a slide rail 2 fixedly connected to a base 1, a slide seat 3 slidably connected to the slide rail 2, an injection mold 5 fixedly mounted on the slide seat 3 by mounting bolts 4, an injection port 9 provided inside the injection mold 5, an installation socket 10 fixedly connected to the injection port 9, and a sliding sealed connection between the installation socket 10 and the installation plug 20. A lead screw 6 is rotatably connected to the base 1, a drive cylinder 7 is fixedly connected to the nut of the lead screw 6, the drive cylinder 7 is fixedly connected to the slide seat 3, and a first drive motor 8 is fixedly connected to the base 1. The output shaft of the first drive motor 8 is fixedly connected to the drive end of the lead screw 6.

[0026] The injection molding assembly connects the second switching valve 22 and the injection mold 5 via a sliding connection between the mounting plug 20 and the mounting socket 10. Molten material is injected into the injection port 9 along the second switching valve 22, and then into the injection mold 5 through the injection port 9. When the injection mold 5 needs to be replaced, the first drive motor 8 drives the lead screw 6 to rotate, which in turn converts the rotary motion of the first drive motor 8 into the linear motion of the drive cylinder 7. The drive cylinder 7 moves the sliding seat 3, which in turn moves the injection mold 5 away from the mounting plug 20, causing the mounting plug 20 to slide away from the mounting socket 10. The mounting bolt 4 can then be unscrewed, allowing for a quick replacement of the injection mold 5. After replacement, the injection mold 5 can be reset to achieve the same result.

[0027] In one instance of this embodiment, please refer to Figures 1-5The hot melt assembly includes an injection tube 11 fixedly connected to the base 1. The discharge end of the injection tube 11 is provided with an extrusion port 15. The extrusion port 15 is slidably sealed to the sealing socket 23. An extrusion screw 12 is rotatably connected inside the injection tube 11. A second drive motor 13 is fixedly installed on the injection tube 11. The output shaft of the second drive motor 13 is fixedly connected to the drive end of the extrusion screw 12. A feed hopper 14 is fixedly connected to the feed end of the injection tube 11.

[0028] The hot melt assembly first holds the raw material through the feed hopper 14, and then the raw material enters the injection tube 11 through the feed end of the injection tube 11. At the same time, the second drive motor 13 drives the extrusion screw 12 to rotate, and then the extrusion screw 12 rotates and pushes the raw material. Meanwhile, the heating assembly in the injection tube 11 heats and melts the raw material. The molten raw material enters the second conversion valve 22 through the extrusion port 15 and the sealing socket 23.

[0029] The working principle of this utility model is as follows: First, the raw material is loaded into the feeding hopper 14. Then, the raw material enters the injection tube 11 through the feeding end. Simultaneously, the second drive motor 13 drives the extrusion screw 12 to rotate, thus pushing the raw material through rotation. At the same time, the heating component inside the injection tube 11 heats and melts the raw material. The molten material enters the second conversion valve 22 through the extrusion port 15 and the sealing socket 23. At this point, the utility model can precisely rotate the second servo motor 26 controlled by the CNC center. The second servo motor 26 drives the second rotary valve core 24 to rotate, thereby replacing the hot melt component connected to the second rotary valve core 24, thus achieving the injection of different types of raw materials. The molten material then enters the connecting pipe 17 through the second rotary valve core 24, then enters the first conversion valve 18 through the first rotary valve core 21, and finally enters the second conversion valve 22 through the connecting pipe 19. At this time, the molten raw material is injected into the injection port 9 along the second conversion valve 22, and then injected into the injection mold 5 through the injection port 9. In addition, the present invention can also drive the first rotary valve core 21 to rotate through the first servo motor 25, thereby replacing the injection assembly connected to the first rotary valve core 21. This realizes the sequential and continuous injection of multiple injection molds 5. When the injection mold 5 needs to be replaced, the first drive motor 8 drives the lead screw 6 to rotate, and the lead screw 6 converts the rotary motion of the first drive motor 8 into the linear motion of the drive cylinder 7. The drive cylinder 7 drives the sliding seat 3 to move, thereby moving the injection mold 5 away from the mounting plug 20, so that the mounting plug 20 slides out of the mounting socket 10. At this time, the mounting bolt 4 can be unscrewed, thus realizing the quick replacement of the injection mold 5. After the replacement is completed, the injection mold 5 can be reset to realize the quick replacement of the injection mold 5.
