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

[0021] like Figures 1 to 11 As shown, this embodiment proposes an environmentally friendly rapid injection molding device for silicone plastic products, including an injection molding machine frame 1. A raw material extrusion device 2 is provided on one side of the injection molding machine frame 1. The raw material extrusion device 2 is a commonly used injection molding technology device in the prior art for melting and extruding silicone plastic raw materials. It is a prior art device known to those skilled in the art. Solid granular silicone plastic raw materials are added into the raw material extrusion device 2, and finally the liquid silicone plastic raw materials are extruded by the raw material extrusion device 2.

[0022] like Figures 1 to 4 As shown, it also includes a partition frame 3, which is fixedly connected to the middle of the injection molding machine frame 1. The partition frame 3 is divided into multiple installation chambers 4. Each installation chamber 4 is provided with a fixed mold 5 and a moving mold 6. The moving mold 6 slides in the installation chamber 4, aligning the fixed mold 5 and the moving mold 6 in the installation chamber 4, so that multiple molding chambers for molding silicone plastic products are formed between the fixed mold 5 and the moving mold 6. The fixed mold 5 and the moving mold 6 are provided with flow channels for coolant to circulate, which is also a conventional technical structure for the fixed mold 5 and the moving mold 6 in the prior art. Molten silicone plastic is injected between the fixed mold 5 and the moving mold 6, so that the molten silicone plastic is formed between the fixed mold 5 and the moving mold 6.

[0023] like Figures 1 to 7 As shown, the injection cylinder 7 is connected to the output end of the raw material extrusion equipment 2. Multiple raw material discharge channels 8 are circumferentially connected on the side wall of the injection cylinder 7. The raw material discharge channels 8 are connected to the corresponding fixed molds 5. An extrusion port 9 is connected to one side of the raw material discharge channel 8. An insulation pipe 10 is connected between the extrusion port 9 and the fixed mold 5. After the silicone plastic raw material is added into the injection cylinder 7, it is injected into one of the raw material discharge channels 8 through the injection cylinder 7. Through the raw material discharge channel 8 and the insulation pipe 10, the silicone plastic melt is injected between the corresponding fixed mold 5 and the moving mold 6. Since the silicone plastic melt does not stagnate in the injection cylinder 7, there is no problem of the silicone plastic melt solidifying in the injection cylinder 7. Although the multiple insulation pipes 10 are used to transport the silicone plastic raw material sequentially, the insulation pipes 10 can effectively isolate the external temperature and prevent the silicone plastic melt from solidifying. This ensures that the silicone plastic melt in the insulation pipes 10 will not solidify before it continues to be transported.

[0024] likeFigures 4 to 7 As shown, the material injection cylinder 7 is provided with a raw material scraping assembly for pushing the silicone raw material, which comprises a scraping impeller 11 and a first driving motor 12. The scraping impeller 11 is rotationally connected in the material injection cylinder 7, and a cavity is arranged in the middle of the scraping impeller 11, which is communicated with the output end of the raw material extrusion equipment 2. The first driving motor 12 is arranged on the partition frame 3, and the output end of the first driving motor 12 is fixedly connected with the scraping impeller 11. The silicone raw material discharged by the raw material extrusion equipment 2 is filled into the cavity in the middle of the scraping impeller 11, and the cavity is communicated with the inside of the material injection cylinder 7. After the silicone melt is discharged from the cavity into the material injection cylinder 7, the first driving motor 12 is started to drive the scraping impeller 11 to rotate, so that the scraping impeller 11 can fully fill the silicone melt from the material injection cylinder 7 into the raw material discharge channel 8.

[0025] As shown in the drawings, Figures 4 to 7 The raw material discharge channel 8 is provided with a slot on the side opposite to the material injection cylinder 7, and an inflatable air bag 13 is arranged in the slot. The middle part of the inflatable air bag 13 is communicated with a gas injection valve pipe 14. The communication mode between the material injection cylinder 7 and the raw material discharge channel 8 is that a plurality of rectangular through grooves are arranged on the corresponding side wall regions of the inside of the material injection cylinder 7 and the raw material discharge channel 8. In order to transport the silicone raw material in the remaining raw material discharge channel 8, the inflatable air bag 13 can be inflated by injecting gas into the inflatable air bag 13 through the gas injection valve pipe 14, so that the inflatable air bag 13 is inflated to block the plurality of rectangular through grooves. The gas injection valve pipe 14 is arranged in the middle part in order to make the inflatable air bag 13 expand more uniformly. The inflatable air bag 13 is provided with a gas extraction pipe 15 penetrating through the inflatable air bag 13. When the raw material discharge channel 8 needs to transport the silicone melt, an external gas extraction device can be used to extract the gas in the inflatable air bag 13 through the gas extraction pipe 15. Because the gas extraction pipe 15 is located outside the raw material discharge channel 8 and is in parallel correspondence with the raw material discharge channel 8, when the gas in the inflatable air bag 13 is extracted, the inflatable air bag 13 is attracted to the direction of the gas extraction pipe 15, so that the inflatable air bag 13 is moved out of the raw material discharge channel 8, and the silicone melt flows in the raw material discharge channel 8. In addition, a cleaning port is arranged on each raw material discharge channel 8, which is convenient for cleaning the residual materials in the raw material discharge channel 8 after shutdown. A cover is arranged on the cleaning port.

[0026] As shown in the drawings, Figures 1 to 3 and Figures 8 to 11As shown, the other side of the injection machine frame 1 is provided with a corresponding connecting structure, which cooperates with the plurality of movable molds 6, and is used to drive the corresponding movable molds 6 to slide in the installation chamber 4. The corresponding connecting structure includes a mounting groove frame 16, a fixed frame 18 and an extension rod 19. The mounting groove frame 16 is arranged on the injection machine frame 1, and a hydraulic drive cylinder 17 is arranged in the mounting groove frame 16. The fixed frame 18 is fixedly connected to the output end of the hydraulic drive cylinder 17. Starting the hydraulic drive cylinder 17 can drive the fixed frame 18 and the components fixedly connected to the fixed frame 18 to move horizontally on the injection machine frame 1; A turnover position adjusting assembly is arranged between the extension rod 19 and the fixed frame 18. The turnover position adjusting assembly includes a circular groove frame 23, a second drive motor 25 and an electromagnetic seat 26. The circular groove frame 23 is fixedly connected to the fixed frame 18. The circular groove frame 23 is rotatably connected to an annular mounting member 24. The extension rod 19 is fixedly connected to one side of the annular mounting member 24. A plurality of fixed cylinder seats 20 are distributed along the center point of the annular mounting member 24. The fixed frame 18 is provided with the second drive motor 25. The annular mounting member 24 is fixedly connected to the output end of the second drive motor 25. The circular groove frame 23 is circumferentially provided with the electromagnetic seat 26. The annular mounting member 24 is circumferentially provided with a ferrous sheet 27 corresponding to the electromagnetic seat 26. In order to make the extension rod 19 correspond to the fixed cylinder seat 20 on the corresponding movable mold 6, the second drive motor 25 is started to drive the annular mounting member 24 to rotate on the circular groove frame 23, so that the extension rod 19 adjusts the position along the center point of the annular mounting member 24, so that the extension rod 19 corresponds to the position of the corresponding fixed cylinder seat 20. After the annular mounting member 24 stops moving, the electromagnetic seat 26 and the ferrous sheet 27 correspond to each other in position. By magnetically connecting the electromagnetic seat 26 and the ferrous sheet 27, the annular mounting member 24 is kept fixed in the circular groove frame 23; An extension rod 19 is provided with a mold engagement assembly, which includes a circular mounting base 28 and a concave push base 32. The circular mounting base 28 is fixedly connected to the extension rod 19. Multiple rotating shafts 29 are arranged circumferentially on the circular mounting base 28. A mounting rod 30 is rotatably connected to each rotating shaft 29. A spring-loaded spring 34 for resetting the mounting rod 30 is provided on each rotating shaft 29. The spring-loaded spring 34 is connected to a rotating shaft on the rotating shaft 29. A ferrous block 31 is fixedly connected to the mounting rod 30. The ferrous block 31 is magnetically connected to the electromagnetic groove 21. The outer arc surface of the concave push base 32 is... Multiple mounting rods 30 are in contact, the concave push seat 32 is adapted to the tapered push rod 22, a spring damper 33 is provided between the concave push seat 32 and the circular mounting seat 28, and a clock spring 34 is used to maintain the reset torque when the concave push seat 32 moves laterally and the multiple mounting rods 30 rotate along the center point of the rotating shaft 29. After the concave push seat 32 stops contacting the tapered push rod 22, when the concave push seat 32 moves towards the moving mold 6, the clock spring 34 can drive the mounting rods 30 and the iron block 31 to reset along the center point of the rotating shaft 29. The mold engagement assembly engages with the moving mold 6. A fixed cylinder seat 20 is fixedly connected to the side of the moving mold 6 near the mounting bracket 16. An electromagnetic groove 21 is circumferentially arranged on the fixed cylinder seat 20. A tapered push rod 22 is located in the middle of the fixed cylinder seat 20. When the extension rod 19 and the circular mounting seat 28 move towards the fixed cylinder seat 20, the ferrous block 31 extends into the fixed cylinder seat 20. The concave push seat 32 first contacts the tapered push rod 22, causing the spring damper 33 to contract. The concave push seat 32 moves towards the circular mounting seat 28, driving multiple mounting rods 30 to rotate along the center point of the rotating shaft 29, causing the ferrous block 31 to enter the engagement position. Inside the corresponding electromagnetic tank 21, the ferrous block 31 is magnetically connected to the electromagnetic tank 21. When the hydraulic drive cylinder 17 drives the fixed frame 18 to move laterally, it also drives the corresponding moving mold 6 to move laterally together, causing the moving mold 6 and the fixed mold 5 to open, allowing the silicone plastic product to be removed from between the moving mold 6 and the fixed mold 5. Then, the moving mold 6 is reset, allowing the moving mold 6 and the fixed mold 5 to fit together, releasing the magnetic connection between the ferrous block 31 and the electromagnetic tank 21. The hydraulic drive cylinder 17 drives the extension rod 19 to reset, and the spring spring 34 can drive the mounting rod 30 and the ferrous block 31 to reset along the center point of the rotating shaft 29, continuing to move the next moving mold 6.

Under the action of the raw material scraping assembly, the silicon plastic raw material is injected into the corresponding fixed mold 5 through the raw material discharge channel 8. At this time, the movable mold 6 and the fixed mold 5 form a plurality of sealed forming chambers. After the silicon plastic raw material is formed between the movable mold 6 and the fixed mold 5, the formed silicon plastic product is removed from between the movable mold 6 and the fixed mold 5 by moving the movable mold 6; During the cooling and forming process of the silicon plastic product between one set of movable mold 6 and fixed mold 5, liquid silicon plastic raw material can be injected between the corresponding movable mold 6 and fixed mold 5 through the other raw material discharge channels 8, realizing continuous extrusion of the silicon plastic raw material.
