[0002] Plastic processing, also known as plastic molding, refers to a series of processes that transform synthetic resins or plastics into plastic products. It typically includes processes such as plastic batching, molding, machining, joining, finishing, and assembly. Injection molding is one of the important technologies in this process. It involves injecting molten plastic material into a mold cavity, which then cools and solidifies to form a plastic shell or outer shell component of the desired shape.

Although this can facilitate the conveying of raw materials, excessive accumulation can easily cause blockages, thereby affecting the work progress and wasting a lot of time. Utility Model Content

A transmission column 9 is fixedly connected to the drive end of the motor 8, and the external rotatable connection of the transmission column 9 is to the inner wall of the fixing block 7. The drive end of the motor 8 drives the transmission column 9 to rotate. A water droplet wheel 10 is fixedly connected to the external side of the transmission column 9, and the transmission column 9 provides force to the motor 8. The driving force is transmitted to the water droplet wheel 10. The outer side of the water droplet wheel 10 is in contact with the outer side of the pulley 11.

A telescopic column 27 is fixedly connected to the right side of the slide plate 24. A second spring 26 is sleeved on the outside of the telescopic column 27. The telescopic column 27 can prevent the second spring 26 from deforming. An injection mold 28 is slidably connected to the outside of the sliding rod 25. The sliding rod 25 can push the injection shell out of the injection mold 28, so that the injection shell falls into the storage box 36. The outside of the support rod 23 is slidably connected to the injection mold. The inner wall of injection mold 28 has a support rod 23, which can improve the stability of injection mold 28 and reduce injection risks. One end of spring 26 is fixedly connected to the left side of slide plate 24, and the other end of spring 26 is fixedly connected to the right side of injection mold 28. A moving column 29 is fixedly connected to the left side of slide plate 24. The outside of moving column 29 is slidably connected to the inner wall of moving block 22. When injection mold 28 and injection mold 21 are in contact, the injection shell is injected. After injection, they are separated. At this time, the injection shell will be embedded in the right side of injection mold 28. Then, threaded rod 20 moves the whole to the left. When moving column 29 touches the inner wall of injection chamber 17, it will push slide plate 24. At the same time, slide plate 24 slides outside support rod 23 and squeezes spring 26. At this time, slide plate 24 will push the injection shell out with slide rod 25.

[0032] Reference Figure 6The cooling assembly includes a cooling box 32, the bottom of which is fixedly connected to the top of the injection chamber 17, which supports the cooling box 32. An input pipe 33 is fixedly connected to the front end of the cooling box 32, through which coolant is input into the inner wall of the injection mold 31 to accelerate the cooling of the injection shell and improve production capacity. An output pipe 34 is fixedly connected to the bottom of the input pipe 33, and the top of the output pipe 34 is fixedly connected to the right side of the cooling box 32 to recycle the coolant after the reaction. A filter plate 35 is slidably connected to the inner wall of the cooling box 32 for filtration and secondary recycling.

[0033] Working principle: First, plastic is poured into the feed inlet 5 and enters the hot melt box 4 for heating and melting. Simultaneously, motor 15 is started, driving the auger 16 to rotate for material transfer. To prevent blockage when the plastic is poured into the feed inlet 5, motor 8 is turned on. Motor 8 rotates the transmission column 9, which in turn rotates the externally fixed water droplet wheel 10. The water droplet wheel 10 drives the pulley 11 and the water droplet wheel 10 to move relative to each other. When the water droplet wheel 10... When the protruding part contacts the pulley 11, the water droplet wheel 10 will apply a relative force to the pulley 11, causing the pulley 11 to squeeze the sliding column 13. At this time, the sliding column 13 will squeeze the spring 12. The sliding column 13 will slide on the inner wall of the feed port 5 and drive the anti-blocking plate 14 to perform unblocking and anti-blocking work inside the feed port 5, thereby greatly improving the feeding rate and saving time. Here, the compression and rebound of the spring 12 can reduce the impact of the force and play a buffering effect, which can greatly improve the stability of the structure.

[0034] When the molten material is fed into the second injection mold 31 through the auger 16, in order to accelerate the molding speed of the plastic shell and prevent the plastic shell from deforming due to external factors during solidification, the coolant in the cooling tank 32 is introduced into the interior of the second injection mold 31 through the input pipe 33 to cool the injection shell. This can accelerate the cooling rate of the injection shell and save time. At the same time, the coolant after the reaction is completed is transmitted through the output pipe 34 and filtered through the filter plate 35 to achieve the effect of recycling, thereby greatly reducing production costs.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
