[0030] 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.
[0031] Reference Figures 1-4This utility model provides an embodiment of a high-efficiency engineering plastic injection molding equipment, including a base 1. A slide rail bracket 20 is fixedly connected to the top of the base 1. A hydraulic rod 10 is fixedly connected to one end of the slide rail bracket 20. The base 1 and the slide rail bracket 20 are made of high-strength gray cast iron, which has good rigidity and shock absorption, supports the overall weight of the equipment, and ensures operational stability. A mold 19 is fixedly connected to the output end of the hydraulic rod 10. Two dust suction ports 11 are fixedly connected to the top of the slide rail bracket 20. The dust suction ports 11 are made of lightweight and corrosion-resistant engineering plastic and can be precisely aligned with the joint between the injection port 12 and the mold 19 to efficiently collect smoke. A support base 2 is fixedly connected to the top of the base 1. A power unit 3 is fixedly connected to the top of the support base 2. Two load-bearing plates 5 are fixedly connected to the top of the base 1. An injection molding machine 4 is fixedly connected to the top of the load-bearing plates 5. The output end of the power unit 3 is fixedly connected to one side of the injection molding machine 4. A feed hopper 13 is fixedly connected to the top of the injection molding machine 4. The end of the injection molding machine 4 away from the power unit 3 slides. The injection molding machine 4 is connected to an injection port 12, and a limiting slider 18 is provided on the outside of the injection port 12. Two fixed seats 16 are fixedly connected to the end of the injection molding machine 4 away from the power unit 3. A pin 14 is slidably connected inside the fixed seat 16. A spring 15 is sleeved on the outside of the pin 14. A limiting ring 17 is fixedly connected to the end of the pin 14 near the spring 15 away from the injection port 12. The injection port 12 abuts against one end of the mold 19. The mold 19 is slidably connected inside the slide rail bracket 20. The limiting slider 18 is slidably connected inside the fixed seat 16. The pin 14 is slidably connected inside the limiting slider 18. The spring 15 is slidably connected inside the fixed seat 16. The base 1 provides an installation reference for all components. The support seat 2 fixes the power unit 3. The load-bearing plate 5 supports the injection molding machine 4. The three work together to ensure the overall rigidity of the equipment during operation and reduce the impact of vibration on molding accuracy. The slide rail bracket 20 not only supports the mold 19, but also ensures the straightness of the mold 19 when sliding through the guide structure, ensuring the precise docking of the mold and the injection port 12.
[0032] Reference Figures 1-4 An air pump 8 is installed at the end of the base 1 furthest from the injection molding machine 4. A filter box 6 is fixedly connected to the input end of the air pump 8. The outer shell of the filter box 6 is made of cold-rolled steel plate, which combines strength and corrosion resistance. Air pipes 7 are fixedly connected to both sides of the filter box 6. The air pipes 7 are made of heat-resistant and corrosion-resistant flexible hoses to ensure stable airflow transmission. The air pipes 7 are fixedly connected to one end of the dust suction port 11. A pull-out filter element 9 is slidably connected inside the filter box 6. The smoke generated by injection molding is collected through the dust suction port 11 at the top of the slide rail bracket 20. Under the negative pressure of the air pump 8, it is transported to the filter box 6 through the air pipe 7. The pull-out filter element 9 in the filter box 6 first physically intercepts large particulate impurities, and then the activated carbon adsorbs toxic and harmful gases. The purified gas is discharged by the air pump 8, which effectively purifies the working environment.
[0033] Working principle: After the equipment is started, the power unit 3, such as a servo motor, outputs power to drive the screw of the injection molding machine 4 to rotate. Engineering plastic granules enter the barrel of the injection molding machine 4 through the feed hopper 13, melting them into a uniform melt. After plasticization, the screw pushes the melt towards the injection port 12. The high-pressure melt is precisely injected into the cavity of the mold 19 through the injection port 12. At this time, the hydraulic rod 10 pushes the mold 19 to slide along the slide rail bracket 20, realizing the tight closure of the moving mold and the fixed mold, providing a stable and sealed space for injection molding. After the mold 19 is completed... Hydraulic rod 10 pulls mold 19 in the reverse direction. When production needs change, such as changing materials or adjusting product specifications requiring replacement of injection port 12, the operator manually pulls out pin 14. Pin 14 slides inside fixed base 16, limiting ring 17 compresses spring 15 and disengages from the slot of limiting slider 18, releasing the lock on injection port 12. At this time, the old injection port 12 can be directly slid off. Then, the injection port 12 adapted to the new production needs is aligned with the installation position, so that the limiting slider 18 on the outside of injection port 12 is engaged in the guide groove of fixed base 16. After releasing pin 14, spring 15 elastically returns to its original position, pushing pin 14 back into the positioning hole of limiting slider 18, completing the rapid fixing of injection port 12, ensuring that the new injection port 12 accurately adapts to production parameters, and improving the production line's response speed to multi-category and multi-specification production.
[0034] During injection molding, the high-temperature plasticizing of the barrel and the high-pressure injection at the injection port 12 generate a small amount of smoke containing volatiles and tiny particles from plastic decomposition. After the air pump 8 starts, a negative pressure is created, attracting the smoke near the injection station. The smoke enters the air pipe 7 through the dust extraction port 11 and is then transported to the filter box 6. The pull-out filter element 9 inside the filter box 6 performs dual purification of the smoke: first, it physically intercepts and filters large particulate impurities, and then activated carbon adsorbs toxic and harmful gases. The purified clean gas is discharged from the equipment via the air pump 8, preventing smoke pollution of the workshop environment and harm to the health of operators. It also reduces product defects caused by impurities in the smoke adhering to the mold 19 and injection port 12, ensuring the cleanliness of the equipment's precision components and indirectly improving the molding quality of plastic parts and the equipment's maintenance cycle.
[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.
