Description

Technical Field

[0001] The invention relates to the technical field of moulds, in particular to a porous exhaust mould structure for automobile rubber parts. Background Art

[0002] In the field of automobile rubber parts manufacturing, the performance of the mold plays a decisive role in product quality and production efficiency. With the vigorous development of the automobile industry, the market has put forward more stringent requirements on the quality, precision and production efficiency of automobile rubber parts, and the traditional automobile rubber parts exhaust mold structure has gradually exposed many drawbacks.

[0003] On the one hand, during the molding process of rubber parts, if the air in the mold cavity and the gas generated by rubber vulcanization cannot be discharged in time and smoothly, defects such as bubbles and holes will be formed inside the rubber parts. These defects not only seriously affect the appearance quality of rubber parts, but also reduce their physical properties and service life, such as causing the sealing performance of rubber seals to decline and the shock-absorbing effect of shock-absorbing rubber parts to be poor. In addition, the design of the existing mold exhaust structure is not reasonable enough, and the exhaust holes are easily blocked by rubber debris, which further aggravates the problem of poor exhaust and increases the difficulty and frequency of mold maintenance; on the other hand, during the production process, rubber debris is easy to remain on the mold surface and in the exhaust holes. The traditional mold cleaning method is relatively cumbersome, and usually requires manual cleaning with simple tools, which is inefficient and has poor cleaning effect. Debris that is difficult to completely remove will affect the molding quality of subsequent rubber parts, resulting in defects in the product, and will also accelerate the wear of the mold, shorten the service life of the mold, and increase production costs; in addition, the mold closing accuracy is directly related to the dimensional accuracy of the rubber parts. In the mold closing process, due to the inaccurate guide structure of the traditional mold, mold closing deviation is prone to occur, resulting in the size of the rubber part not meeting the design requirements and increasing the scrap rate of the product. Moreover, mold closing deviation may also cause local wear of the mold, reduce the service life of the mold, and affect the continuity and stability of production.

These guide rods 303 are evenly distributed, and a guide sleeve 304 is slidably connected to the outer periphery. The guide rod 303 and the guide sleeve 304 cooperate with each other, and when the hydraulic rod 302 pushes the upper mold 305 to move, they play a role of stable guidance, effectively preventing the upper mold 305 from deflecting or shaking during the movement, and ensuring the high precision of the mold closing process.

The telescopic rods 402 can be telescopically moved under the control of the controller 7 according to the actual cleaning needs. The output ends of the two telescopic rods 402 are fixedly connected with fixed plates 403. When the telescopic rods 402 are extended or shortened, the fixed plates 403 will move accordingly. On one side of the two fixed plates 403, multiple bases 404 are fixedly installed, and one end of the multiple bases 404 is fixedly connected with a top column 405, so that they are respectively adapted to the multiple exhaust holes 308, and can go deep into the exhaust holes 308 for cleaning. In addition, multiple bumps 406 are provided on the outer surfaces of the multiple top columns 405. These bumps 406 increase the friction and contact area between the top column 405 and the inner wall of the exhaust hole 308. When the top column 405 penetrates into the exhaust hole 308 for cleaning, it can more effectively scrape off the rubber debris and impurities remaining in the exhaust hole 308, ensuring the unobstructed flow of the exhaust hole 308, thereby ensuring the exhaust effect of the mold and the molding quality of the rubber part.

[0026] The replacement assembly includes mounting threaded rods 407 each fixedly mounted on one end of a plurality of top columns 405, and the plurality of mounting threaded rods 407 are respectively connected to the inner threads of the plurality of bases 404; Specifically, a mounting threaded rod 407 is fixedly mounted at one end of each of the plurality of top columns 405, and the mounting threaded rods 407 are respectively matched with the threads inside the plurality of bases 404. When the top columns 405 are worn or damaged during long-term use, the operator can easily remove the top columns 405 from the bases 404 by simply rotating the top columns 405 and using the threaded connection between the mounting threaded rod 407 and the bases 404, and then install a new top column 405, thereby ensuring that the cleaning mechanism 4 always maintains a good cleaning effect and reducing the mold maintenance time and cost caused by damage to the cleaning parts.

Guide plates 505 are obliquely installed on both sides of the openings of the two dust collection ports 504. Specifically, collection boxes 501 are fixedly installed at both ends of the outer side of the workbench 1. The collection boxes 501 are used to collect dust, debris and other impurities sucked out during the vacuuming process. They have a large volume, which reduces the number of frequent cleanings. Vacuum cleaners 502 are fixedly installed on the upper parts of the two collection boxes 501. The vacuum cleaners 502 serve as the power source for vacuuming and suck dust and debris into the vacuum pipe 503 through strong suction. The upper parts of the two vacuum cleaners 502 are fixedly connected to the vacuum pipes 503, which transmit the suction generated by the vacuum cleaners 502 to the vacuum port 504.

[0028] The upper part of the two dust suction pipes 503 is fixedly connected with a dust suction port 504. In order to improve the dust suction efficiency, guide plates 505 are obliquely installed on both sides of the openings of the two dust suction ports 504. The inclined design of the guide plates 505 can guide the dust-containing gas to enter the dust suction port 504 more smoothly, avoid the gas from running around, improve the dust suction effect, and ensure that the working environment around the mold remains clean.

[0029] The cooling assembly includes a fixing seat 506 fixedly mounted on the upper part of the two suction ports 504, and a plurality of cooling fans 507 are arranged inside the two fixing seats 506; Specifically, a fixing seat 506 is fixedly installed on the upper part of the two suction ports 504, and the fixing seat 506 provides a stable installation position for the cooling fan 507. A plurality of cooling fans 507 are arranged inside the two fixing seats 506. During the mold closing operation, the plurality of cooling fans 507 start to operate, and the cold air blown out can reduce the temperature of the mold surface, which helps the rubber parts to cool and shape quickly. At the same time, the airflow generated by the cooling fan 507 can further assist the gas discharge, enhance the exhaust effect, reduce the defects of the rubber parts caused by the overheating of the mold, such as deformation, aging, etc., and improve the quality and production efficiency of the rubber parts.

[0030] The guide assembly in the guide heating mechanism 6 includes a plurality of guide blocks 601 fixedly mounted on the upper portion of the workbench 1, a guide groove 602 is provided on one side of each of the plurality of guide blocks 601, a slider 603 is slidably connected inside each of the plurality of guide grooves 602, and the plurality of sliders 603 are fixedly connected to both sides of the upper mold 305 respectively; Specifically, the guide assembly of the guide heating mechanism 6 provides precise guidance for the mold closing process to ensure the mold closing accuracy of the mold. On the upper part of the workbench 1, a plurality of guide blocks 601 are fixedly installed, and these guide blocks 601 are evenly distributed to provide a guide reference for the movement of the upper mold 305. On one side of the plurality of guide blocks 601, a guide groove 602 is provided, and a slider 603 is slidably connected inside the plurality of guide grooves 602, and the plurality of sliders 603 are respectively fixedly connected to both sides of the upper mold 305. When the hydraulic rod 302 pushes the upper mold 305 to move, the slider 603 slides in the guide groove 602, further ensuring the stability and accuracy of the movement of the upper mold 305, so that the upper mold 305 can be accurately docked with the lower mold 306. At the same time, when the slider 603 slides in the guide groove 602, it can also drive the upper mold 305 to remain stable in the horizontal direction, prevent it from shaking, effectively avoid mold closing deviation, and ensure the dimensional accuracy of the rubber part.

[0031] The heating assembly includes a plurality of heating plates 604 disposed on the upper portion of the upper mold 305 , and a temperature sensor 605 is disposed on the upper portion of the upper mold 305 ; Specifically, a plurality of heating plates 604 are provided on the upper part of the upper mold 305, and the heating plates 604 heat the mold by converting electrical energy into thermal energy. In order to accurately control the temperature of the mold, a temperature sensor 605 is also provided on the upper part of the upper mold 305. The temperature sensor 605 can monitor the temperature of the upper mold 305 in real time and feed back the temperature data to the controller 7. The controller 7 is electrically connected to the temperature sensor 605, and according to the preset temperature value, the heating power of the heating plate 604 is adjusted to ensure that the temperature of each position on the mold is always uniform. When the temperature sensor 605 detects that the temperature is lower than the preset value, the controller 7 will increase the current of the heating plate 604 and increase the heating power; if the temperature is higher than the preset value, the heating power of the heating plate 604 is reduced to provide a stable thermal environment for the vulcanization molding of the rubber parts, ensure the stability of the performance of the rubber parts, reduce product quality problems caused by uneven temperature, and improve the product qualification rate.

[0032] A controller 7 is fixedly installed on one side of the workbench 1, and the controller 7 is electrically connected to the temperature sensor 605. A plurality of lighting lamps 8 are arranged on the outer side of the upper part of the support frame 301; Specifically, on one side of the workbench 1, a controller 7 is fixedly installed. The controller 7 is electrically connected to the temperature sensor 605, receives the temperature data fed back by the temperature sensor 605, and accurately controls the heating power of the heating plate 604 according to the preset temperature value to ensure the stability of the mold temperature. At the same time, the controller 7 can also control the extension and contraction of the hydraulic rod 302, realize the precise mold closing and mold opening operations of the mold closing mechanism 3, realize the automation and intelligent control of the entire mold structure, and improve production efficiency and product quality. On the upper outer side of the support frame 301, a plurality of lighting lamps 8 are arranged to provide sufficient lighting for the operator during the entire production process, so that the operator can observe the mold closing and mold opening conditions of the mold, as well as the molding quality of the rubber parts, so as to ensure the smooth progress of the production process.

[0033] Working principle: First, the hydraulic rod 302 begins to extend under the control of the controller 7. The hydraulic rod 302 pushes the upper mold 305 fixedly connected to its output end to move downward along the guide rod 303. The guide sleeve 304 outside the guide rod 303 plays a stabilizing guiding role, ensuring that the upper mold 305 can move accurately toward the lower mold 306 to avoid deviation during the mold closing process.

[0034] When the upper mold 305 moves downward, the sliders 603 fixedly connected to both sides of the upper mold 305 slide in the guide grooves 602 of the guide blocks 601, further ensuring the stability and accuracy of the movement of the upper mold 305, so that the upper mold 305 can be accurately docked with the lower mold 306. When the sliders 603 slide in the guide grooves 602, the upper mold 305 is also driven to remain stable in the horizontal direction to prevent it from shaking.

[0035] As the upper mold 305 approaches the lower mold 306, the heating plate 604 starts to heat the mold. The temperature sensor 605 monitors the temperature of the upper mold 305 in real time and feeds back the temperature data to the controller 7. The multiple temperature sensors 605 detect the temperature at different positions of the upper mold 305, so that the controller 7 adjusts the heating power of the heating plate 604 according to the preset temperature value to ensure that the temperature at each position on the mold is always uniform, providing a stable thermal environment for the vulcanization molding of the rubber part. If the temperature sensor 605 detects that the temperature is lower than the preset value, the controller 7 will increase the current of the heating plate 604 to increase the heating power; if the temperature is higher than the preset value, the heating power of the heating plate 604 will be reduced.

[0036] When the hydraulic rod 302 pushes the upper mold 305 to completely close the mold with the lower mold 306, the mold closing groove 307 inside the lower mold 306 and the upper mold 305 form a closed cavity together, and the prepared rubber raw material is injected into the cavity. During the injection of the rubber raw material, the air in the cavity and the gas generated by the rubber during the vulcanization process will be discharged through the multiple exhaust holes 308 opened at the bottom of the upper mold 305 and the top of the lower mold 306.

[0037] At the same time, a strong suction force is generated at the dust suction port 504 through the dust suction pipe 503, and the guide plates 505 installed obliquely on both sides of the opening of the dust suction port 504 can guide the dust-containing gas to enter the dust suction port 504 more smoothly, thereby improving the dust suction efficiency. During the dust suction process, multiple cooling fans 507 also start to operate, and the cold air blown out can reduce the temperature of the mold surface, which helps the rubber parts to cool and shape quickly, and also reduces the defects of the rubber parts caused by overheating of the mold. The airflow generated by the cooling fan 507 can further assist the gas discharge and enhance the exhaust effect.

[0038] After the rubber part is vulcanized, the hydraulic rod 302 drives the upper mold 305 to move upward along the guide rod 303, so that the upper mold 305 is separated from the lower mold 306. At this time, the telescopic rod 402 extends, pushing the fixed plate 403 to move toward the mold, and the multiple top pillars 405 fixedly installed on one side of the fixed plate 403 approach the mold. The multiple protrusions 406 arranged on the outer surface of the top pillar 405 can fully contact the surface of the multiple exhaust holes 308 arranged on the mold. Under the push of the top pillar 405, the rubber debris, impurities, etc. remaining in the exhaust holes 308 are cleaned up.

[0039] If the top column 405 is worn or damaged during the cleaning process, it can be replaced with the replacement assembly of the cleaning mechanism 4. The mounting threaded rod 407 fixedly mounted at one end of the top column 405 is connected to the inner thread of the base 404. The operator only needs to rotate the top column 405 to remove it from the base 404, and then install a new top column 405, ensuring that the cleaning mechanism 4 always maintains a good cleaning effect.

[0040] During the entire production process, multiple lighting lamps 8 are arranged on the outer side of the upper part of the support frame 301 to provide sufficient lighting for the operator, so that the operator can observe the mold closing and opening conditions of the mold, as well as the molding quality of the rubber parts, etc. At the same time, the controller 7 can not only control the temperature of the heating plate 604 and the extension and contraction of the hydraulic rod 302, but also adjust the working state of the dust collection mechanism 5 and the cleaning mechanism 4 according to actual production needs, so as to realize the automation and intelligent control of the entire mold structure and improve the production efficiency and product quality.

[0041] In summary, a porous exhaust mold structure for automotive rubber parts achieves efficient and high-quality production of rubber parts through the synergy between various mechanisms. It also has multiple functions such as mold cleaning, dust collection and cooling, guided heating, and automatic control, effectively meeting the actual needs of automotive rubber parts production.
