Technical Field

[0001] This invention relates to the field of injection molding equipment technology, and more specifically to an injection molding machine. Background Technology

[0002] Injection molding machines are the main molding equipment used to mold thermoplastic or thermosetting plastics into various shapes of plastic products using plastic molds. Injection molding machines are divided into vertical, horizontal, and all-electric types. Injection molding machines heat plastics and apply high pressure to the molten plastic, causing it to be injected and fill the mold cavity. In recent years, China's plastics machinery industry has made great progress not only in the mid-range injection molding machine field, but also in the high-end injection molding machine field. China's market share of plastics machinery is expected to gradually expand. Under the existing technology, injection molding machines cannot solve the oxidation problem of unformed materials. Therefore, in order to solve the above problems, this application proposes an injection molding machine that can enhance the anti-oxidation ability of the internal materials of the injection molding machine. Summary of the Invention

[0019] Through observation Figures 1 to 10 An exemplary working process for anti-oxidation, as shown in the figure, is as follows:

[0020] An injection molding machine includes a knob 01, a turntable 19 fixedly connected to the knob 01, a screw 20 fixedly connected to the turntable 19, four evenly distributed toothed spurs 18 meshing with the turntable 19, each baffle 03 rotatably connected to one toothed spur 18, each arc-shaped plate 02 fixedly connected to one toothed spur 18, and each baffle 03 slidably connected to the lower end of an arc-shaped plate 02. After the injection molding machine is assembled, rotating the knob 01 causes the turntable 19 fixedly connected to it to rotate. When the turntable 19 rotates, the screw 20 fixedly connected to it rotates, and simultaneously, the four evenly distributed toothed spurs 18 meshing with it rotate. When the toothed column 18 rotates, the corresponding arc-shaped plate 02 fixed to it will rotate, causing the four arc-shaped plates 02 to separate from each other until the distance between them expands to the maximum, thus connecting the internal environment with the external environment. At the same time, injection molding material can be injected into the device. When injecting material, care should be taken to avoid the column rod on the turntable 19 to prevent the material from accumulating on the wall, affecting the normal operation of the device, and thus affecting the airtightness of the device. When the material injection is completed, the knob 01 should be turned in the opposite direction immediately to reconnect the four arc-shaped plates 02, isolate the external environment, greatly reduce the impact of external factors on the material, isolate external oxygen, and thus achieve the effect of anti-oxidation.

[0021] Through observation Figures 1 to 10 An exemplary workflow for cleaning, based on the content shown in the diagram, is as follows:

[0022] A cleaning ring 21 is engaged with the screw 20. After the injection molding machine is assembled, the screw 20 connected to it rotates as the knob 01 is turned. When the screw 20 rotates, the cleaning ring 21 engaged with it will rotate and move along the thread direction. When the knob 01 is turned in the forward direction, the cleaning ring 21 will rotate upward, so that the cleaning ring 21 moves to the top of the screw 20 and then the injection material is injected. After the injection is completed, the cleaning ring 21 is at the top of the screw 20 and overlaps with the turntable 19, which is more conducive to the injection of material. Then the knob 01 is turned in the reverse direction, so that the device runs and drives the cleaning ring 21 to move downward, so that the cleaning ring 21 cleans the inner wall of the injection cylinder 04. As the arc plate 02 is completely closed, the cleaning ring 21 will run to the bottom of the injection cylinder 04, thereby completing the cleaning effect.

[0023] Through observation Figures 1 to 10 An exemplary filtering process, based on the content shown in the figure, is as follows:

[0024] The filter 22 is fixed to the lower end of the screw 20, and the separator 23 is rotatably connected to the lower end of the filter 22. Several through holes are respectively provided on the filter 22 and the separator 23. After the injection molding machine is assembled, the screw 20 is rotated by turning the knob 01, which in turn drives the filter 22 fixed to the lower end of the screw 20 to rotate. Since the separator 23 is rotatably connected to the lower end of the filter 22, and both the separator 23 and the filter 22 are provided with through holes, when the knob 01 is rotated in the forward direction, the holes provided on the separator 23 and the filter 22 will be connected, so that the injection material in the injection cylinder 04 can enter the next process. At the same time, due to the existence of the through holes, larger block materials will be exposed, thereby achieving the filtering effect.

[0025] Through observation Figures 1 to 10 An exemplary working process for pressurization, as shown in the diagram, is as follows:

[0026] One of the fixed rings 06 is rotatably connected to the filter 22, and two agitating rings 07 are rotatably connected to both ends of one of the fixed rings 06 respectively. The conical discharge port 12 is rotatably connected to the other end of one of the agitating rings 07, and the other fixed ring 06 is rotatably connected to the other end of the other agitating ring 07.

[0027] The connecting rod 08 is slidably connected to the other fixed ring 06. The conical feeder 24 is fixed to the connecting rod 08. The push plate 09 is fixed to the other end of the connecting rod 08. The threaded end of the output shaft 10 is threadedly connected to the lower end of the push plate 09. After the injection molding machine is assembled and the injection material is filtered, the injection material will enter the fixed ring 06. Then, the output shaft 10 is rotated, causing the threaded end of the output shaft 10 to rotate, which in turn drives the lower end of the push plate 09 threaded to it to move along the thread direction, causing the connecting rod 08 fixedly connected to the upper end of the push plate 09 to move. As the push plate 09 moves forward continuously, the conical feeder 24 fixed to its front end will continue to push, driving the injection material into the next process, thereby achieving the effect of pressurization.

[0028] Through observation Figures 1 to 10 An exemplary working process of agitation, as shown in the figure, is as follows:

[0029] The transmission gear 26 is connected to the output shaft 10 via a belt. The adapter gear set 27 is meshed with the transmission gear 26. Two friction belts 28 are meshed with both ends of the adapter gear set 27. Each agitator ring 07 is frictionally connected to one friction belt 28. An output rod 25 is rotatably connected to the two friction belts 28. After the injection molding machine is assembled, as the output shaft 10 rotates, the output shaft 10 will drive the transmission gear 26 connected to it via the belt to rotate. When the transmission gear 26 rotates, the adapter gear set 27 meshing with it will rotate accordingly, thereby driving the two friction belts 28 meshing with it to rotate. As the two friction belts 28 rotate, the output rod 25 rotatably connected to them will rotate, causing the corresponding agitator ring 07 meshing with it to rotate. This causes the material inside the agitator ring 07 to be circulated and agitated, making the performance of the injection molding material more complete, thus achieving the agitation effect.

[0030] Through observation Figures 1 to 10 An exemplary working process for vibration, as shown in the figure, is as follows:

[0031] An adapter 13 is connected to the output rod 25 via a belt, and a vibrating column 14 is fixed to the adapter 13. The feeding tube 15 indirectly contacts the vibrating column 14. After the injection molding machine is assembled, the rotation of the two friction belts 28 drives the output rod 25, which is rotatably connected to them, to rotate. When the conveying rod 25 rotates, it will drive the adapter 13, which is connected to it via a belt, to rotate. When the adapter 13 rotates, the vibrating column 14, which is rotatably connected to it, will rotate, thereby intermittently contacting the feeding tube 15. Through the protrusions provided on the vibrating column 14, it indirectly contacts the feeding tube 15, thereby achieving the vibration effect.

[0032] Through observation Figures 1 to 10An exemplary working process of the separation environment, as shown in the figure, is as follows:

[0033] The meshing bevel gear set 30 is fixedly connected to the other end of the output shaft 10, and the rectangular plate 16 is connected to the other end of the meshing bevel gear set 30 via a belt. When the injection molding machine is assembled, the injection material is fed into the feeding pipe 15 through the output rod 25. The output shaft 10 rotates, which drives the meshing bevel gear set 30 fixed on it to rotate. When the meshing bevel gear set 30 rotates, the rectangular plate 16 connected to its other end via a belt will rotate, causing the rectangular plate 16 to open. Then the injection mold can be placed into the mold box 17. Then, through the reverse rotation of the output shaft 10, the rectangular plate 16 is fastened towards the mold box 17, separating the inside of the mold box 17 from the outside environment, thereby achieving the effect of separating the environment.

[0034] Through observation Figures 1 to 10 An exemplary workflow that can be automatically derived from the content shown in the figure is as follows:

[0035] The rectangular plate 16 is rotatably connected to the mold box 17, and the receiving plate 29 is slidably connected inside the mold box 17. The spring column is fixed between the receiving plate 29 and the lower end of the mold box 17. When the injection molding machine is assembled, the rectangular plate 16 is fastened to the mold box 17, and the mold enters the mold box 17. Then, the required injection material is injected into the mold through the feeding pipe 25. After the material is injected, the mold will apply downward pressure, which will generate pressure on the receiving plate 29, thereby causing the receiving plate 29 to squeeze the spring column fixed at its lower end. After cooling, the rectangular plate 16 is opened by rotating the output shaft 10. Then, the spring column will expand outward and push the receiving plate 29 fixed on it, thereby pushing out the molded model, thus achieving the effect of automatic ejection.
