Description

Technical Field

[0001] The present invention relates to the technical field of plastic recycling and injection molding, and specifically provides an injection mold for feeding plastic recycling to an injection molding machine. Background Art

[0002] With the global emphasis on environmental protection and resource conservation, plastic recycling and reuse have become an important trend in the industry's development. Plastic recycling not only helps reduce environmental pollution but also saves raw materials and lowers production costs. In the injection molding industry, reusing recycled plastics after treatment in injection mold production is an effective way to achieve sustainable development. An injection mold is a process equipment that injects plastic materials into a mold at high temperature to form plastic products of the desired shape. With the progress of technology, injection mold technology is also constantly evolving.

[0003] In the field of injection molding technology, the control of the curing speed of plastic solutions and the mixing uniformity are key factors affecting the quality of injection molded products and production efficiency. In traditional injection molding processes, the curing speed of plastic solutions is often controlled by preset process parameters. However, due to problems such as fluctuations in raw material quality, changes in environmental temperature, and uneven mixing, it is easy to cause inconsistent curing speeds. Inconsistent curing speeds can result in different degrees of curing in different parts of the product, thereby affecting the overall performance of the product. For example, in injection molding, if the curing speed of the plastic solution is inconsistent, it may cause fluctuations in mechanical properties such as the hardness and strength of the product. Uneven curing may also lead to appearance defects such as uneven gloss, color difference, shrinkage holes, and cracks on the product surface, affecting the aesthetics and market acceptance of the product. In addition, different density plastic solutions generated during the injection process are usually difficult to effectively recycle and reuse, which not only causes waste of raw materials but also increases production costs and environmental pollution.

[0032] The heating tank 6 is fixedly installed on the top surface of the injection molding machine body 5. A cover plate 7 is fixedly installed on the top surface of the heating tank 6. A conveying pipe 8 is fixedly installed on the top surface of the cover plate 7. A stirring blade 9 is rotatably connected inside the heating tank 6. A servo motor 10 is fixedly installed on the top surface of the injection molding machine body 5. The output shaft of the servo motor 10 is connected to the stirring blade 9. An ultrasonic vibrator 11 is fixedly installed on the top surface of the cover plate 7. A plurality of transparent windows 12 are arranged on the side wall of the heating tank 6. The mixing mechanism further includes a detection component and an adjustment component;

[0033] The injection molding mechanism is arranged on the workbench 2. The injection molding mechanism includes:

[0034] Two support plates 23 are respectively fixedly installed on both sides of the top surface of the base 1. A top plate 24 is fixedly installed on the top surfaces of the two support plates 23. A lower mold 25 and an upper mold 26 are respectively arranged between the two support plates 23. A temperature sensor 35 is fixedly installed on the side wall of the lower mold 25. A heat dissipation fan 37 is fixedly installed inside the top plate 24. The injection molding machine body 5 injects plastic solution into the lower mold 25 through a transmission pipe 52. The injection molding mechanism further includes a clamping component;

[0035] The conveying component is arranged on the base 1 and is used for recycling the plastic solution in the lower mold 25 and the upper mold 26.

[0036] As a preferred implementation manner in this embodiment, please refer to Figure 1 、 Figure 2 And Figure 3 As shown, the detection component includes: a fixed block 13, which is fixedly installed on the side wall of the heating tank 6. A detector 14 is fixedly installed on the side wall of the fixed block 13 facing the transparent window 12.

[0037] As a preferred implementation manner in this embodiment, please refer to Figure 5 As shown, the adjustment component includes: an additive storage box 15, which is fixedly installed on the top surface of the cover plate 7. An inlet 16 is opened on the top surface of the additive storage box 15. A partition 17 is rotatably connected to one side of the inlet 16. Oblique blocks 18 are fixedly installed on both sides inside the additive storage box 15. The two oblique blocks 18 are symmetrically arranged. A leakage groove 19 is opened on the bottom surface inside the additive storage box 15. Three torsion springs 20 are evenly arranged on the side wall of the leakage groove 19. A pressing plate 21 is rotatably connected to the top surfaces of the three torsion springs 20. A micro pressure pump 22 is fixedly installed on the top surface of the additive storage box 15.

[0038] Through the above features, the curing speed of the plastic solution in the heating tank 6 can be detected, and the curing speed of the plastic solution can be adjusted, and the plastic solution in the heating tank 6 can be stratified according to different densities. Specifically, first, the plastic solution is injected into the cover plate 7 through the delivery pipe 8. At this time, the staff turns on the servo motor 10 through the controller 4, so that the stirring blade 9 connected to the output shaft of the servo motor 10 rotates in the heating tank 6 to stir and mix the plastic solution in the heating tank 6. During this process, the detector 14 detects the curing speed of the plastic solution in the heating tank 6 through the transparent window 12;

[0039] Further, when the curing speeds of the plastic solutions in the heating tank 6 are inconsistent, the detection data of the detector 14 at this time will be transmitted to the controller 4, and the controller 4 will then convert it into an electrical signal acceptable to the micro pressure pump 22 to automatically turn on the micro pressure pump 22 and pressurize the inside of the additive storage box 15. At this time, when the pressure is too high, the pressing plate 21 will squeeze the torsion spring 20 to deform the torsion spring 20. At this time, the additive in the additive storage box 15 can fall into the inside of the heating tank 6 through the leakage groove 19 and mix with the plastic solution in the heating tank 6. During this process, the detector 14 will not stop detecting the curing speed of the plastic solution in the heating tank 6 until the detector 14 detects that the curing speeds in the heating tank 6 are consistent. Then, the micro pressure pump 22 will stop pressurizing, and the pressing plate 21 will automatically close due to the restoring force of the torsion spring 20 to seal the leakage groove 19 to prevent the additive in the additive storage box 15 from flowing into the heating tank 6. If it is necessary to add additives to the additive storage box 15, only need to open the partition plate 17, and the staff can inject additives into the additive storage box 15 through the inlet 16. When the stirring is completed and the curing speeds are consistent, the ultrasonic vibrator 11 starts to work, so that the plastic solution with a large density is located below the inside of the heating tank 6, and the plastic solution with a small density is located above the inside of the heating tank 6 to ensure that the seals of the plastic solutions injected into the lower mold 25 are basically the same. Then, it is injected into the lower mold 25 through the transfer pipe 52;

[0040] It is worth mentioning that the detector 14 can be used for detection by differential scanning calorimetry or infrared spectroscopy, etc. Differential scanning calorimetry is a thermal analysis method that determines parameters such as the thermal transition temperature and enthalpy of a sample by measuring the heat flow difference between the sample and a reference during heating or cooling. In the detection of curing speed, DSC can be used to monitor the curing reaction of plastics during heating, and the curing speed can be deduced by measuring the change in heat flow of the curing reaction. DSC testing has the characteristics of high precision and high sensitivity and can accurately reflect the curing behavior of plastics. Infrared spectroscopy is a method of analyzing the composition and structure of a sample by measuring the absorption spectrum of the sample in the infrared region. In the detection of curing speed, FTIR can be used to monitor the change of functional groups in plastics during curing, thereby inferring the progress and speed of the curing reaction. Infrared spectroscopy has the advantages of fast speed, non-destructive, and high sensitivity, and is suitable for the detection of curing speed of various plastics

[0041] As a preferred implementation manner in this embodiment, please refer to Figure 6 、 Figure 7 、 Figure 9 and Figure 10 As shown, the clamping assembly includes: two L-shaped plates 27, the two L-shaped plates 27 are respectively rotatably connected to the adjacent surfaces of the two support plates 23. Moving grooves 28 are formed on the adjacent surfaces of the two L-shaped plates 27. Limiting rods 29 are fixedly installed inside the two moving grooves 28. Moving blocks 30 are slidably connected to the outer surfaces of the two limiting rods 29. Spring one 31 is arranged on the top surfaces of the two moving blocks 30. Pressing blocks 32 are fixedly installed on the adjacent surfaces of the two moving blocks 30. The bottom surfaces of the two pressing blocks 32 are respectively attached to the top surfaces on both sides of the upper mold 26. A driving motor 36 is fixedly installed on the side wall of one of the lower molds 25. The output shaft of the driving motor 36 is connected to the side wall of one of the L-shaped plates 27. Electric push rods one 33 are respectively fixedly installed on both sides of the bottom surface of the top plate 24. Electromagnets 34 are fixedly installed on the output shafts of the two electric push rods one 33. The two sealing rings 43 are mutually adsorbed with the top surface of the upper mold 26

[0042] As a preferred implementation manner in this embodiment, please refer to Figure 3 and Figure 8 As shown, the conveying assembly includes: a fixed ring 44, the fixed ring 44 is fixedly installed inside the base 1. An electric push rod two 45 is fixedly installed on the top surface of the fixed ring 44. A circular groove 46 is formed on the top surface of the workbench 2 below the lower mold 25. A circular box 47 is slidably connected to the inner wall of the circular groove 46. The bottom surface of the circular box 47 is fixedly connected to the output end of the electric push rod two 45. A circular magnet 48 is fixedly installed inside the circular box 47. A diaphragm pump 50 is fixedly installed on the rear side wall of the base 1. A connecting pipe one 49 and a connecting pipe two 51 are respectively arranged on both sides of the diaphragm pump 50. The other end of the connecting pipe one 49 is communicated with the top surface of the circular box 47. The other side of the connecting pipe two 51 is communicated with the inside of the heating tank 6

[0043] Liquid leakage holes are provided on the bottom surface of the lower mold 25 and the top surface of the upper mold 26. Seals are provided on the inner walls of the two liquid leakage holes. The seal includes: two connecting blocks 38, which are respectively fixedly installed on both sides of the liquid leakage hole. Sliding grooves 39 are provided on the adjacent surfaces of the two connecting blocks 38. A sliding block 40 is slidably connected inside the sliding groove 39. A second spring 41 is provided on the top surface of the sliding block 40. Connecting rods 42 are fixedly installed on the adjacent surfaces of the two sliding blocks 40. A sealing ring 43 is fixedly installed on the side walls of the two connecting rods 42. The sealing ring 43 has the same diameter as the liquid leakage hole. The two sealing rings 43 can be adsorbed to the circular magnet 48 respectively;

[0044] With the above features, the lower mold 25 and the upper mold 26 can be clamped, and plastic solutions with different densities in the lower mold 25 and the upper mold 26 can be taken out and re-transported to the heating tank 6 for re-mixing. Specifically, after the transfer pipe 52 injects the plastic in the heating tank 6 into the lower mold 25, the staff turns on the first electric push rod 33 through the controller 4, causing the first electric push rod 33 to descend. At this time, the electromagnet 34 is energized and adsorbed to the top surface of the upper mold 26. While the first electric push rod 33 descends, the upper mold 26 adsorbed to the electromagnet 34 descends synchronously, causing the upper mold 26 and the lower mold 25 to close. The two pressing blocks 32 fix the top surface of the upper mold 26 to prevent the lower mold 25 and the upper mold 26 from separating. After the lower mold 25 and the upper mold 26 are closed, the electromagnet 34 will be powered off, and the first electric push rod 33 will automatically rise to its original position. At this time, the cooling fan 37 located above the upper mold 26 will start to accelerate the solidification of the plastic solution inside the lower mold 25 and the upper mold 26. At this time, the temperature sensor 35 will detect the temperature in the lower mold 25;

[0045] Further, after the temperature is reduced to a certain level, the plastic solution with a higher density will be located at the lower part inside the lower mold 25, and the plastic solution with a lower density will be located at the upper part inside the lower mold 25. At this time, the staff can turn on the drive motor 36 through the controller 4, causing one of the L-shaped plates 27 connected to the output shaft of the drive motor 36 to rotate, and the other L-shaped plate 27 will also rotate accordingly, making the upper mold 26 located below. At this time, the staff controls the second electric push rod 45 to rise, and the round box 47 connected to the output end of the second electric push rod 45 rises from the round groove 46 until it covers the liquid leakage hole on the upper mold 26. At this time, the sealing ring 43 is adsorbed by the circular magnet 48, and the sliding block 40 and the second spring 41 connected to the sealing ring 43 will both move down with the sealing ring 43. During the downward movement of the sliding block 40, the second spring 41 will be squeezed and deformed. When the sealing ring 43 is adsorbed by the circular magnet 48, the plastic solution with a lower density will flow into the round box 47 through the liquid leakage hole on the upper mold 26. At this time, the staff can turn on the diaphragm pump 50 through the controller 4 to make the plastic solution in the round box 47 be re-transported to the heating tank 6 through the first connecting pipe 49 and the second connecting pipe 51. When the solution with a lower density has flowed out, the second electric push rod 45 will drive the round box 47 to move down. At this time, the sealing ring 43 is no longer adsorbed by the circular magnet 48, and the sealing ring 43 will be subjected to the resilience of the second spring 41 to seal the liquid leakage hole;

[0046] Further, after the plastic solution in the lower mold 25 and the upper mold 26 solidifies, the first electric push rod 33 will move down again. When the first electric push rod 33 reaches the top surface of the upper mold 26, the electromagnet 34 is energized, and then the first electric push rod 33 drives the upper mold 26 to rise, making it convenient for the work to take out the finished product.

[0047] Working principle:

[0048] During use, the plastic solution is injected into the heating tank 6 through the delivery pipe 8. Subsequently, the servo motor 10 is started by the controller 4 to drive the stirring blade 9 to rotate inside the heating tank 6, fully stirring and mixing the plastic solution. At the same time, the detector 14 monitors the curing speed of the plastic solution in the heating tank 6 in real time through the transparent window 12. If the detected curing speeds are inconsistent, the controller 4 will automatically start the micro pressure pump 22 to pressurize the additive storage box 15, so that the additive is appropriately added into the plastic solution in the heating tank 6 through the adjustment mechanism of the leakage trough 19 and the pressing plate 21 until the detector 14 confirms that the curing speeds are consistent. After the curing speed of the plastic solution is adjusted to be consistent, the ultrasonic vibrator 11 starts to work, using the energy of ultrasonic waves to stratify the components with different densities in the plastic solution inside the heating tank 6, ensuring that the solution with a higher density is located below and the solution with a lower density is located above to ensure that the properties of the plastic solution injected into the lower mold 25 are basically the same. The stratified plastic solution is injected into the lower mold 25 through the transfer pipe 52. At this time, the first electric push rod 33 descends under the control of the controller 4, and at the same time, the electromagnet 34 is energized to adsorb the top surface of the upper mold 26, causing it to close with the lower mold 25. During the closing process, the pressing block 32 is pushed by the first spring 31 to ensure that the upper mold 26 is firmly clamped. After the injection molding is completed, the cooling fan 37 is started to accelerate the solidification process of the plastic solution inside the lower mold 25 and the upper mold 26. The temperature sensor 35 monitors the temperature inside the lower mold 25 in real time to ensure that the plastic solution solidifies within a suitable temperature range. During the solidification process, due to the temperature drop, the plastic solutions with different densities will naturally stratify inside the lower mold 25. When recycling is required, the drive motor 36 is started to drive the L-shaped plate 27 and the upper mold 26 to rotate downward. Subsequently, the second electric push rod 45 rises to drive the round box 47 to cover the liquid leakage hole of the upper mold 26, and uses the circular magnet 48 to adsorb the sealing ring 43, so that the plastic solution with a lower density flows into the round box 47 through the liquid leakage hole. Through the diaphragm pump 50, the first connecting pipe 49, and the second connecting pipe 51, the recycled plastic solution is re-transported back to the heating tank 6 for re-mixing. After the plastic inside the lower mold 25 and the upper mold 26 is completely solidified, the first electric push rod 33 descends again, the electromagnet 34 is energized to adsorb the upper mold 26, and then the first electric push rod 33 drives the upper mold 26 to rise, making it convenient to take out the finished product.
