Description

Technical Field

[0001] The utility model relates to the technical field of compound die injection molding machines, and more specifically, it relates to a compound die injection molding machine. Background Art

[0002] In the existing technology, the device structure of the compound die injection molding machine is usually relatively simple. This simplified design often leads to low working efficiency, thus having an adverse impact on production efficiency and product quality. The working efficiency of the compound die injection molding machine is directly related to production costs and production capacity. Therefore, improving the working efficiency is the key to enhancing the performance of the equipment.

[0003] Secondly, in the existing technology, the compound die injection molding machine usually needs to open a heat dissipation cavity in the lower die base and transport coolant or cooling water in the heat dissipation cavity to achieve the cooling of the mold. However, the internal structure of the conveying pipeline of this cooling system is often relatively simple and lacks flexibility. It cannot adjust the conveying flow rate and discharge speed of the coolant or cooling water according to actual production requirements. The limitations of this design lead to unstable cooling effects, which may affect the temperature control of the mold, and further affect the quality and precision of plastic products.

[0004] In addition, although some compound die injection molding machine devices adopt mechanisms to adjust the flow rate of coolant and cooling water, these mechanisms are usually simple in structure and cannot ensure the stability after adjustment. During the operation of the equipment, due to the influence of equipment vibration or external factors, the adjusted flow rate may change, which will lead to unstable temperature control of the mold, and further affect the quality and precision of plastic products. The existence of this instability not only reduces production efficiency but also may lead to inconsistent product quality, having an adverse impact on the production process and the final product.

A limiting mechanism is arranged on the outside of the tube 10, and the limiting mechanism includes a limiting sleeve 13, a limiting frame 14, a rotating plate 15, a giving groove 16, a limiting plate 17, a fixed block 18, a return block 19 and a spring 20. The limiting sleeve 13 is slidably arranged on the outside of the adjusting tube 10, the limiting frame 14 is fixedly connected to one side of the limiting sleeve 13, the rotating plate 15 is movably arranged on the outside of the adjusting tube 10, the giving groove 16 is opened on the rotating plate 15, the limiting plate 17 is connected to one side of the limiting frame 14, the fixed block 18 is fixedly connected to the outside of the adjusting tube 10, the return block 19 is connected to one side of the rotating plate 15, and the spring 20 is arranged on one side of the fixed block 18.

[0034] A sliding groove 21 is provided in the adjusting tube 10 , and a sliding block 22 is provided on the outer side of the sliding sleeve 7 . The sliding block 22 is slidably arranged in the sliding groove 21 .

[0035] A guide rail 23 is disposed on the outer side of the adjusting tube 10 , and a guide groove 24 is formed on the inner side of the limiting sleeve 13 , and the guide groove 24 is adapted to the guide rail 23 .

[0036] A matching block 25 is provided on one side of the adjusting block 9 , a matching groove 26 is provided on the sliding sleeve 7 , and the matching block 25 is slidably arranged in the matching groove 26 .

[0037] In this embodiment, when the flow rate needs to be adjusted, first rotate the rotating plate 15. The rotating plate 15 will drive the return block 19 to move. The return block 19 will cooperate with the fixed block 18 to squeeze the spring 20. At the same time, the rotating plate 15 drives the relief groove 16 to move. When the spring 20 is squeezed to the limit, the positions of the relief groove 16 and the limit plate 17 just correspond. Push the limit sleeve 13 upward. The limit sleeve 13 will slide along the guide rail 23 and the guide groove 24. Then the limit sleeve 13 will drive the limit frame 14 and the limit plate 17 to move. Then the limit frame 14 and the limit plate 17 will pass through the relief groove 16. At the same time, the limit sleeve 13 will cooperate with the rotating plate 15 to squeeze the push spring 3. When the push spring 3 is squeezed to the limit, release the rotating plate 15. The spring 20 pushes the return block 19 to reset. Then the return block 19 will drive the rotating plate 15 to reset. Then the rotating plate 15 drives the relief groove 16 to reset, so that the corresponding limit plate 17 is engaged on one side of the rotating plate 15. Then the rotating sleeve 6 loses the limit of the limit sleeve 13. Then rotate the rotating sleeve 6. The rotating sleeve 6 drives the screw rod 4 to rotate. Since the nut sleeve 5 is movably sleeved on the outer side of the screw rod 4 through threads, and the sliding groove 21 and the sliding block 22 limit the sliding sleeve 7, then the nut sleeve 5 will drive the sliding sleeve 7 to slide along the screw rod 4. At the same time, the sliding sleeve 7 will drive the sliding block 22 to move along the sliding groove 21. Then the sliding sleeve 7 will push the adjusting block 9 to move. The adjusting block 9 will drive the adjusting plate 12 to slide along the adjusting groove 11. Due to the inclined structure design of the adjusting groove 11 and the adjusting plate 12, when the adjusting plate 12 drives the adjusting block 9 to slide, it will gather inward. At the same time, the adjusting block 9 will drive the mating block 25 to slide along the mating groove 26. Then the tapered blocks 8 will gradually abut against each other. Then the tapered blocks 8 will cooperate with the adjusting block 9 to squeeze the tapered spring 2, so that the gap of the tapered spring 2 changes, thereby changing the flow rate of the cooling water and the coolant. At the same time, the movement of the adjusting block 9 changes the cross-sectional area at the corresponding position in the adjusting pipe 10, thereby further changing the flow rate of the cooling water and the coolant. After adjusting to the appropriate value, stop rotating the rotating sleeve 6. Then rotate the rotating plate 15 again. The rotating plate 15 squeezes the spring 20 through the return block 19. After squeezing to the limit, the position of the limit plate 17 corresponds to the position of the relief groove 16. The push spring 3 pushes the limit sleeve 13 to reset, so that the limit sleeve 13 drives the limit frame 14 and the limit plate 17 to reset. When the push spring 3 is completely reset, release the rotating plate 15. Then the spring 20 pushes the return block 19 to reset. Then the rotating plate 15 follows the return block 19 to reset, so that the limit frame 14 is engaged on one side of the rotating plate 15 through the limit plate 17, so that the limit sleeve 13 is stably sleeved on the outer side of the rotating sleeve 6. Due to the limitation of the guide rail 23 and the guide groove 24 on the limit sleeve 13, the limit sleeve 13 will not rotate. And due to the frictional force between the limit sleeve 13 and the rotating sleeve 6, the movement of the rotating sleeve 6 is restricted, preventing the rotating sleeve 6 from rotating, and thus ensuring the stability of the adjusted flow rate.

[0038] Please refer to Figures 1-4, as an embodiment of an injection molding device: The injection molding device includes a feed hopper 27, a motor 28, a conveying bin 29, and an extrusion rod 30. The feed hopper 27 is detachably installed above the conveying bin 29, the motor 28 is detachably installed on one side of the conveying bin 29, and the output end of the motor 28 is connected to one end of the extrusion rod 30. The conveying bin 29 is detachably installed on the bracket 1, and the extrusion rod 30 is movably installed in the conveying bin 29.

[0039] A fixing plate 31 is provided on the bracket 1. A upper mold base 32 is provided on one side of the fixing plate 31. A lower mold base 33 is provided on one side of the upper mold base 32. A hydraulic cylinder 34 is provided on one side of the fixing plate 31. A hydraulic rod 35 is provided at the output end of the hydraulic cylinder 34. One end of the hydraulic rod 35 is connected to the upper mold base 32. A collection box 36 is detachably provided inside the bracket 1.

[0040] A heat dissipation cavity 37 is formed inside the lower mold base 33. Conveying pipes 38 are connected to both sides of the lower mold base 33. The conveying pipes 38 are fixedly connected to the adjusting pipe 10. A connecting pipe 39 is provided on one side of the rotating sleeve 6. One end of the connecting pipe 39 is movably connected to the rotating sleeve 6. The other end of the connecting pipe 39 is connected to an external device.

[0041] A guide rod 40 is provided on one side of the fixing plate 31. The upper mold base 32 is slidably connected to the guide rod 40.

[0042] More specifically, when the device needs to be used, first add the raw materials into the feed hopper 27, then turn on the motor 28. The motor 28 drives the extrusion rod 30 to rotate. Due to the spiral structure design on the outside of the extrusion rod 30, the extrusion rod 30 will convey the raw materials forward in the conveying bin 29. Then the raw materials will enter the molding cavity between the lower mold base 33 and the upper mold base 32. Then, cool water or coolant is input into the heat dissipation cavity 37 through the conveying pipe 38 by an external device to cool it. After cooling, turn on the hydraulic cylinder 34. The hydraulic cylinder 34 drives the upper mold base 32 to move through the hydraulic rod 35 connected to the output end. Then the upper mold base 32 will slide along the guide rod 40, so that the upper mold base 32 and the lower mold base 33 are separated. Then the molded product will fall into the collection box 36. Then turn on the hydraulic cylinder 34 again, so that the hydraulic cylinder 34 pushes the upper mold base 32 and the lower mold base 33 to close the mold through the hydraulic rod 35. Then continue to operate according to the above process.

[0043] In summary, when the overall device is in use or operation: when the flow rate needs to be adjusted, first rotate the rotating plate 15. The rotating plate 15 will drive the return block 19 to move. The return block 19 will cooperate with the fixed block 18 to squeeze the spring 20. At the same time, the rotating plate 15 drives the relief groove 16 to move. When the spring 20 is squeezed to the limit, the positions of the relief groove 16 and the limit plate 17 just correspond. Push the limit sleeve 13 upward. The limit sleeve 13 will slide along the guide rail 23 and the guide groove 24. Then the limit sleeve 13 will drive the limit frame 14 and the limit plate 17 to move. Then the limit frame 14 and the limit plate 17 will pass through the relief groove 16. At the same time, the limit sleeve 13 will cooperate with the rotating plate 15 to squeeze the push spring 3. When the push spring 3 is squeezed to the limit, release the rotating plate 15. The spring 20 pushes the return block 19 to reset. Then the return block 19 will drive the rotating plate 15 to reset. Then the rotating plate 15 drives the relief groove 16 to reset, so that the corresponding limit plate 17 is engaged on one side of the rotating plate 15. Then the rotating sleeve 6 loses the limit of the limit sleeve 13. Then rotate the rotating sleeve 6. The rotating sleeve 6 drives the screw rod 4 to rotate. Since the nut sleeve 5 is movably sleeved on the outer side of the screw rod 4 through threads, and the sliding groove 21 and the slider 22 limit the sliding sleeve 7, then the nut sleeve 5 will drive the sliding sleeve 7 to slide along the screw rod 4. At the same time, the sliding sleeve 7 will drive the slider 22 to move along the sliding groove 21. Then the sliding sleeve 7 will push the adjusting block 9 to move. The adjusting block 9 will drive the adjusting plate 12 to slide along the adjusting groove 11. Due to the inclined structure design of the adjusting groove 11 and the adjusting plate 12, when the adjusting plate 12 drives the adjusting block 9 to slide, it will gather inward. At the same time, the adjusting block 9 will drive the mating block 25 to slide along the mating groove 26. Then the tapered blocks 8 will gradually abut against each other. Then the tapered blocks 8 will cooperate with the adjusting block 9 to squeeze the tapered spring 2, so that the gap of the tapered spring 2 changes, thereby changing the flow rate of the cooling water and the coolant. At the same time, the movement of the adjusting block 9 changes the cross-sectional area at the corresponding position in the adjusting pipe 10, thereby further changing the flow rate of the cooling water and the coolant. After adjusting to the appropriate value, stop rotating the rotating sleeve 6. Then rotate the rotating plate 15 again. The rotating plate 15 squeezes the spring 20 through the return block 19. After squeezing to the limit, the position of the limit plate 17 corresponds to the position of the relief groove 16. The push spring 3 pushes the limit sleeve 13 to reset, so that the limit sleeve 13 drives the limit frame 14 and the limit plate 17 to reset. When the push spring 3 is completely reset, release the rotating plate 15. Then the spring 20 pushes the return block 19 to reset. Then the rotating plate 15 follows the return block 19 to reset, so that the limit frame 14 is engaged on one side of the rotating plate 15 through the limit plate 17, so that the limit sleeve 13 is stably sleeved on the outer side of the rotating sleeve 6. Due to the limit of the guide rail 23 and the guide groove 24 on the limit sleeve 13, the limit sleeve 13 will not rotate, and the frictional force between the limit sleeve 13 and the rotating sleeve 6 contact surface, thereby restricting the movement of the rotating sleeve 6 and preventing the rotating sleeve 6 from rotating, thereby ensuring the stability of the adjusted flow rate.

[0044] When the device needs to be used, first add the raw materials into the feed hopper 27, and then turn on the motor 28. The motor 28 drives the extrusion rod 30 to rotate. Due to the spiral structure design on the outside of the extrusion rod 30, the extrusion rod 30 will convey the raw materials forward in the conveying bin 29, and then the raw materials will enter the forming bin between the lower die holder 33 and the upper die holder 32. Then, through an external device, cooling water or coolant is input into the heat dissipation cavity 37 through the conveying pipe 38 to cool it. After cooling, turn on the hydraulic cylinder 34. The hydraulic cylinder 34 drives the upper die holder 32 to move through the hydraulic rod 35 connected to the output end. Then, the upper die holder 32 will slide along the guide rod 40, causing the upper die holder 32 and the lower die holder 33 to separate. Then, the formed product will fall into the collection box 36. Then, turn on the hydraulic cylinder 34 again, so that the hydraulic cylinder 34 pushes the upper die holder 32 and the lower die holder 33 to close the mold through the hydraulic rod 35, and then continue to operate according to the above process.
