Description

Technical Field

[0001] The utility model relates to the technical field of vulcanization molding die stripping, and more specifically, to a vulcanization molding die stripping mechanism. Background Art

[0002] In the current design of vulcanization mold stripping mechanisms, although there are some effective stripping methods, these methods are often accompanied by high costs and operational limitations, especially in the application of hydraulic and pneumatic systems.

[0003] First of all, many existing vulcanization molding mold ejection mechanisms use hydraulic cylinders and hydraulic rods to eject materials. Although this method is relatively stable and powerful in force output and is suitable for ejection operations of large or heavy molds, the construction and maintenance costs of this system are high. The hydraulic system needs to regularly replace the hydraulic oil and check the seal and pressure system to prevent oil leakage and insufficient pressure. In addition, the maintenance of the hydraulic system requires professional technical support, which increases the operating cost and complexity.

[0004] Secondly, some existing technologies use pneumatic methods for stripping. Compared with hydraulic systems, pneumatic systems are lower in cost and simpler to install. However, the main limitation of pneumatic systems is that it is difficult to control the gas delivery speed, which may result in the speed of the stripping action being unable to be accurately adjusted, thereby affecting the demolding quality of the product. Improper speed may cause damage to the product in the mold or incomplete detachment, increasing the scrap rate.

[0005] In addition, pneumatic ejection mechanisms usually require multiple movable rods to work simultaneously to ensure uniform ejection. However, this design usually cannot adjust the pressure of a single movable rod individually, which is particularly inconvenient when different pressures need to be applied to different parts of the mold. Uneven pressure distribution may cause uneven ejection of products in the mold, affecting the overall quality and consistency of the product. Utility Model Content

[0036] In this embodiment, when the device needs to be used, the raw material is first placed above the lower mold core 4, and then the hydraulic cylinder 19 is turned on. The hydraulic cylinder 19 drives the upper mold base 3 and the upper mold core 6 to move downward through the hydraulic rod 20 connected to the output end, and then the upper pressing plate 5 cooperates with the lower mold core 4 to press the raw material, and then the hydraulic rod 20 continues to drive the upper mold base 3 and the upper mold core 6 to move downward, so that the upper mold base 3 and the upper pressing plate 5 cooperate to press the spring 21 set in the middle, so that the molding work is completed, and then the hydraulic cylinder 19 drives the hydraulic rod 20 to rise, thereby driving the upper mold base 3 and the upper mold core 6 The gas rises, and then the compressed gas is transported into the delivery pipe 7 through the external delivery equipment, and then the gas enters the lower mold core 4 through the delivery pipe 7, and then the gas accumulates to a certain pressure and enters the fixed pipe 11 to push the sealing plate 13 open, and then the sealing block 24 set on the fixed plate 12 will be separated from the sealing groove 23 set on one side of the sealing plate 13, and then the gas will enter the top of the fixed plate 12, and then the sealing plate 13 will cooperate with the sliding sleeve 14 to compress the first push spring 10 set in the middle, and then the sealing plate 13 will drive the top plate 8 to rise through the movable rod 9, and enter at the same time The gas in the fixed tube 11 will push the top plate 8 up through the air hole 22 opened at the top of the rotating sleeve 15, thereby lifting the product on the lower mold core 4 and completing the material removal work. When it is necessary to adjust the opening pressure of a single top plate 8 according to the product, first remove the fixed sleeve 40 from the lower mold core 4, then remove the fixed tube 11 and the components installed in the fixed tube 11, fix the fixed tube 11 to prevent the fixed tube 11 from rotating, and then rotate the rotating sleeve 15. Since the rotating sleeve 15 and the sliding sleeve 14 are movably connected through threads, and since the sliding rod 16 limits the sliding sleeve 14, The sliding sleeve 14 will not rotate, and then the sliding sleeve 14 will move downward along the sliding rod 16, and then the sliding sleeve 14 will squeeze the first push spring 10 sleeved on the outer side of the movable rod 9, thereby changing the opening pressure of the sealing plate 13. After the adjustment is completed, refer to the above process to reinstall the fixed tube 11 and other components to their original positions. The setting of the guide block 17 and the guide groove 18 can ensure the stable installation of the fixed tube 11 and the rotating sleeve 15, and prevent the rotating sleeve 15 from easily rotating in the lower mold core 4. Then use the fixed sleeve 40 to stably install the fixed tube 11 in the lower mold core 4.

[0037] See also Figure 1-4As an implementation method of the adjustment device: the adjustment device includes a connecting pipe 25, a matching groove 26, a matching block 27, an adjustment block 28, a threaded sleeve 29, an adjustment sleeve 30, a slide groove 31 and a slider 32. The connecting pipe 25 is connected to one end of the connecting pipe 25, the matching groove 26 is opened in the connecting pipe 25, the matching block 27 is slidably installed in the matching groove 26, the matching block 27 is fixedly connected to one side of the adjustment block 28, the threaded sleeve 29 is movably installed at one end of the connecting pipe 25, the adjustment sleeve 30 is movably arranged in the connecting pipe 25, the slide groove 31 is opened at the top of the adjustment sleeve 30, the slider 32 is fixedly arranged at the bottom of the adjustment block 28, and the slider 32 is slidably installed in the slide groove 31.

[0039] A bellows 35 is provided at one end of the adjusting sleeve 30 , and the bellows 35 is fixedly installed at one end of the adjusting sleeve 30 .

[0040] More specifically, when it is necessary to adjust the overall delivery flow rate of the compressed gas, the threaded sleeve 29 is rotated. Since the threaded sleeve 29 and the outer side of the adjusting sleeve 30 are movably connected by threads, and since the slider 32 and the slide groove 31 are mutually limited, the adjusting sleeve 30 will not rotate, and then the adjusting sleeve 30 will slide along the connecting pipe 25, and at the same time, the adjusting sleeve 30 will drive the bellows 35 to extend, and then the adjusting sleeve 30 will drive the adjusting block 28 to move, and then the adjusting block 28 will drive the matching block 27 to slide in the matching groove 26, and at the same time, the adjusting block 28 will drive The slider 32 connected at one end slides in the slide groove 31.

At the same time, the movement of the adjusting block 28 will change the cross-sectional area of ​​the corresponding position in the connecting pipe 25, thereby effectively changing the flow rate of the compressed gas. When the adjustment is appropriate, stop rotating the threaded sleeve 29.

[0041] In summary, when the overall equipment is in use or running: when the equipment needs to be used, first place the raw material above the lower mold core 4, then turn on the hydraulic cylinder 19, the hydraulic cylinder 19 drives the upper mold base 3 and the upper mold core 6 to move downward through the hydraulic rod 20 connected to the output end, and then the upper pressing plate 5 will cooperate with the lower mold core 4 to press the raw material, and then the hydraulic rod 20 will continue to drive the upper mold base 3 and the upper mold core 6 to move downward, so that the upper mold base 3 and the upper pressing plate 5 cooperate to press the spring 21 set in the middle, so as to complete the molding work, and then the hydraulic cylinder 19 drives the hydraulic rod 20 to rise, thereby driving the upper mold The seat 3 and the upper mold core 6 rise, and then the compressed gas is transported into the delivery pipe 7 through the external delivery equipment, and then the gas enters the lower mold core 4 through the delivery pipe 7, and then the gas accumulates to a certain pressure and enters the fixed pipe 11 to push the sealing plate 13 open, and then the sealing block 24 set on the fixed plate 12 will be separated from the sealing groove 23 set on one side of the sealing plate 13, and then the gas will enter the top of the fixed plate 12, and then the sealing plate 13 will cooperate with the sliding sleeve 14 to compress the first push spring 10 set in the middle, and then the sealing plate 13 will drive the top plate 8 to rise through the movable rod 9 At the same time, the gas entering the fixed tube 11 will push the top plate 8 to rise through the air hole 22 opened at the top of the rotating sleeve 15, thereby lifting the product on the lower mold core 4 to complete the stripping work. When it is necessary to adjust the opening pressure of a single top plate 8 according to the product, first remove the fixed sleeve 40 from the lower mold core 4, then remove the fixed tube 11 and the components installed in the fixed tube 11, fix the fixed tube 11 to prevent the fixed tube 11 from rotating, and then rotate the rotating sleeve 15. Since the rotating sleeve 15 and the sliding sleeve 14 are movably connected through threads, and since the sliding rod 16 limits the sliding sleeve 14 , so the sliding sleeve 14 will not rotate, and then the sliding sleeve 14 will move downward along the sliding rod 16, and then the sliding sleeve 14 will squeeze the first push spring 10 sleeved on the outer side of the movable rod 9, thereby changing the opening pressure of the sealing plate 13. After the adjustment is completed, refer to the above process to reinstall the fixed tube 11 and other components to their original positions. The setting of the guide block 17 and the guide groove 18 can ensure the stable installation of the fixed tube 11 and the rotating sleeve 15, and prevent the rotating sleeve 15 from easily rotating in the lower mold core 4. Then, the fixed sleeve 40 can be used to reinstall the fixed tube 11 stably in the lower mold core 4.

[0042] When the overall delivery flow rate of the compressed gas needs to be adjusted, the threaded sleeve 29 is rotated. Since the threaded sleeve 29 and the outer side of the adjusting sleeve 30 are movably connected by threads, and since the slider 32 and the slide groove 31 are mutually limited, the adjusting sleeve 30 will not rotate, and then the adjusting sleeve 30 will slide along the connecting pipe 25, and at the same time, the adjusting sleeve 30 will drive the bellows 35 to extend, and then the adjusting sleeve 30 will drive the adjusting block 28 to move, and then the adjusting block 28 will drive the matching block 27 to slide in the matching groove 26, and at the same time, the adjusting block 28 will drive one end of the connecting pipe 25 to slide. The connected slider 32 slides in the slide groove 31. Due to the inclined structure of the matching block 27 and the matching groove 26, when the adjusting block 28 slides, the adjusting block 28 will gather inward at the same time, and then the conical block 34 will press together, and then the second push spring 33 connected to one side of the conical block 34 will be compressed, and then the gap between the second push springs 33 will gradually narrow. At the same time, the movement of the adjusting block 28 will change the cross-sectional area of ​​the corresponding position in the connecting pipe 25, thereby effectively changing the flow rate of the compressed gas. When the adjustment is appropriate, stop rotating the threaded sleeve 29.
