Description

Technical Field

[0001] The invention relates to the technical field of tire manufacturing, and in particular to a mold for tire production. Background Art

[0002] In the tire manufacturing industry, molds are used to form the tire cavity, which determines the appearance and performance of the tire. The design and manufacture of molds need to take into account many factors, including dimensional accuracy, interchangeability, thermal conductivity, exhaust effect, etc.

[0003] The existing tire molds have the following major problems: First, the positioning accuracy between the mold and the center mechanism is low, which affects the size of the tire cavity. Due to the limitation of the integral structure, the connection between the mold and the center mechanism is easily affected by external factors, resulting in low positioning accuracy, which affects the size of the tire cavity. Second, the interchangeability between different patterns of the same mold specification is extremely poor, resulting in high mold costs. When it is necessary to replace molds with different patterns, the mold needs to be redesigned and manufactured, which not only increases the cost of the mold, but also prolongs the production cycle. Third, the mold has poor thermal conductivity, resulting in a long vulcanization time, affecting production and high energy consumption costs. In order to improve the thermal conductivity of the mold, the existing technology usually adopts the method of adding a heat source medium channel to the mold. However, although this method can improve the thermal conductivity of the mold, it will also increase the complexity and manufacturing cost of the mold. Fourth, the exhaust effect is not good, resulting in air holes, which affects the appearance quality of the tire. The existing technology usually sets exhaust holes in the mold, but such exhaust holes are easily blocked, which affects the exhaust effect and product quality. Summary of the invention

[0004] The purpose of the present invention is to solve the following main problems of the existing tire mold: first, the positioning accuracy between the mold and the central mechanism is low, which affects the size of the tire cavity. Due to the limitation of the integral structure, the connection between the mold and the central mechanism is easily affected by external factors, resulting in low positioning accuracy, which affects the size of the tire cavity. Second, the interchangeability between different patterns of the same specification of the mold is extremely poor, resulting in high mold cost. When it is necessary to replace the mold with a different pattern, the mold needs to be redesigned and manufactured, which not only increases the cost of the mold, but also prolongs the production cycle. Third, the mold has poor thermal conductivity, resulting in a long vulcanization time, affecting the output and high energy consumption cost. In order to improve the thermal conductivity of the mold, the existing technology usually adopts a method of adding a heat source medium channel in the mold. However, although this method can improve the thermal conductivity of the mold, it will also increase the complexity and manufacturing cost of the mold.

[0021] In summary, due to the use of the above-mentioned technology for a tire production mold, the beneficial effects of the present invention are:

[0022] 1. A mold for tire production: The present invention adopts a split structure. The mold and the center mechanism are connected by a positioning piece. The positioning piece is located in the sink groove of the lower hot plate. There is a clearance fit between the inner wall of the positioning piece and the outer circle size of the center mechanism. When the mold is placed on the vulcanizer as a whole, the lower sidewall connecting cover matches it to achieve preliminary positioning. At the same time, the positioning piece can avoid damage to the center mechanism. At the same time, the upper hot plate and the large ring of the mold sleeve are connected by bolts to achieve the positioning of the upper mold. At the same time, the lower sidewall connecting cover is connected to the center mechanism through the positioning piece. When the center mechanism descends, the positioning piece and the lower sidewall connecting cover are adapted to each other. During the descent, the lower sidewall connecting cover achieves concentricity under the action of the clamp force to achieve final positioning. The above can effectively reduce the influence of external factors on the connection accuracy, thereby improving the positioning accuracy between the mold and the center mechanism and ensuring the accurate size of the tire cavity.

[0023] 2. A mold for tire production: The mold of the present invention is designed as a universal modular structure. The pattern cavity is adapted to the size of the guide side block. The pattern cavity only needs to be processed according to the outer diameter size and the matching size to achieve patterns of different specifications and interchangeable assembly. The pattern block is cut into 8 equal parts as a whole. When different patterns are required, the interchange can be achieved by replacing the pattern blocks with different patterns. At the same time, the upper cavity sidewall and the lower cavity sidewall are processed according to the size of the upper sidewall connecting cover and the lower sidewall connecting cover 3, so that they can be interchanged. This design can not only greatly reduce the cost of the mold, but also shorten the production cycle and improve production efficiency.

[0024] 3. A mold for tire production: When the upper and lower mold surfaces of a traditional vulcanizer are preheated, the heat is transferred to the tread blocks through heat conduction, which results in a time-consuming and uneven temperature field for the overall mold temperature to reach the required level. The mold of the present invention is provided with a vulcanizing medium channel, and the coverability structure is improved. The inner cavity of the mold sleeve is a steam chamber, and the vulcanizing medium can enter the steam chamber through a metal hose connection to heat the tread blocks, effectively reducing the preheating time, while reducing the temperature difference of the overall structure of the mold and improving product quality. This design can effectively improve the thermal conductivity of the mold, shorten the vulcanization time, increase production, and reduce energy consumption costs.

[0025] 4. A mold for tire production: In the mold of the present invention, since the pattern blocks are assembled, in addition to being provided with traditional air holes, the assembled type can effectively exhaust the tire embryo during the mold closing process and the extrusion process from the outside to the inside. The pattern is pieced together piece by piece, and there are corresponding gaps, which can also achieve the exhaust function and effectively prevent the exhaust holes from being blocked, thereby improving the exhaust effect and improving product quality.

[0047] An upper hot plate 28 is fixedly mounted on the first connecting oil cylinder, a die sleeve large ring 13 is fixedly mounted on the upper hot plate 28 by bolts, an upper tire side connection cover 21 is fixedly mounted on the die sleeve large ring 13, an active mold driving connector 18 is fixedly mounted on the upper tire side connection cover 21 by bolts, and the active mold driving connector 18 is connected to the active mold connecting oil cylinder 104 by a snap ring;

[0048] The upper cavity sidewall 16 is fixedly installed on the upper sidewall connecting cover 21 by bolts, and the upper toe steel ring 17 is fixedly installed on the upper cavity sidewall 16 by bolts. The upper sidewall connecting cover 21 is provided with a guide rail 23, and the guide rail 23 is provided with a sliding block 22. The sliding block 22 is fixedly installed with a pattern block 15 by bolts, and the pattern block 15 is provided with a guide slider member 11, and the guide slider member 11 is fixedly installed with a mold sleeve inner ring 4 by bolts. A through-connecting screw 14 is penetrated through the mold sleeve large ring 13, the mold sleeve inner ring 4, the guide slider member 11 and the sliding block 22, and the through-connecting screw 14 is threadedly connected to the lower sidewall connecting cover 3.

[0049] The present invention adopts a split structure. The mold and the center mechanism are connected by a positioning piece 30. The positioning piece 30 is located in the sink groove of the lower hot plate 29. There is a clearance fit between the inner wall of the positioning piece 30 and the newly created outer circle size. When the mold is placed on the vulcanizer as a whole, the lower sidewall connecting cover 3 matches it to achieve preliminary positioning. At the same time, the positioning piece 30 can avoid damage to the center mechanism. At the same time, the upper hot plate 28 and the mold sleeve large ring 13 are connected by bolts to achieve the positioning of the upper mold. At the same time, the lower sidewall connecting cover 3 is connected to the center mechanism 26 through the positioning piece 30. When the center mechanism 26 descends, the positioning piece 30 and the lower sidewall connecting cover 3 are of matching size. During the descent, the lower sidewall connecting cover 3 is concentric under the action of the clamp force to achieve final positioning. The above can effectively reduce the influence of external factors on the connection accuracy, thereby improving the positioning accuracy between the mold and the center mechanism 26 and ensuring the accurate size of the tire cavity.

[0050] The mold sleeve inner ring 4 is provided with a mold sleeve outer ring 10, a mold sleeve inner cavity 9 is formed between the mold sleeve outer ring 10 and the mold sleeve inner ring 4, a mold sleeve vulcanization medium inlet 6 is provided on the mold sleeve outer ring 10, and a mold sleeve vulcanization medium outlet 8 is provided on the sleeve outer ring;

[0051] When the upper and lower mold surfaces of a traditional vulcanizer are preheated, the heat is transferred to the pattern block 15 through heat conduction, which results in a time-consuming and uneven temperature field for the overall mold temperature to reach the required level. The mold of the present invention is provided with a vulcanizing medium channel, and the coverability structure is improved. The inner cavity 9 of the mold sleeve is a steam chamber. The vulcanizing medium can enter the steam chamber through a metal hose to heat the pattern block 15, effectively reducing the preheating time, while reducing the temperature difference of the overall mold structure and improving product quality. This design can effectively improve the thermal conductivity of the mold, shorten the vulcanization time, increase production, and reduce energy consumption costs.

[0052] The pattern block 15 comprises a guide side block 151 connected to the sliding block 22 by bolts, and the guide side block 151 is fixed with a pattern cavity 152 by bolts;

[0053] The mold design of the present invention is a universal modular structure. The pattern cavity 152 is adapted to the size of the guide side block 151. The pattern cavity only needs to be processed according to the outer diameter size and the matching size to achieve patterns of different specifications and interchangeable assembly. The pattern block is cut into 8 equal parts as a whole. When different patterns are required, interchangeability can be achieved by replacing pattern blocks of different patterns. At the same time, the upper cavity sidewall and the lower cavity sidewall are processed according to the size of the upper sidewall connecting cover and the lower sidewall connecting cover, so that interchangeability can be achieved. This design can not only greatly reduce the cost of the mold, but also shorten the production cycle and improve production efficiency.

[0054] A positioning pin 7 is provided between the guide slider 11 and the inner ring 4 of the mold sleeve.

[0055] The guide slider 11 is fixed with a stopper 5 by means of bolts.

[0056] A self-locking device 12 is provided on the vulcanizing upper machine platform.

[0057] The lower sidewall connection cover 3 is provided with an extended connection block 2 .

[0058] In the mold of the present invention, since the pattern block 15 is of an assembled type, in addition to being provided with traditional air holes, the assembled type can effectively exhaust the tire blank during the mold closing process and the extrusion process from the outside to the inside. Moreover, the pattern is pieced together piece by piece, and there are corresponding gaps, which can also achieve the exhaust function and effectively prevent the exhaust holes from being blocked, thereby improving the exhaust effect and improving product quality.

[0059] Working principle: When the tire blank enters the vulcanizer and is shaped, it is molded and vulcanized. At this time, the connecting cylinder pushes the upper hot plate 28 to move downward. When its height reaches the specified position, the active mold connecting cylinder 104 is powered off. At this time, the active mold connecting cylinder 104 no longer exerts an upward force on the active mold driving connector 18. The tread block 15 opens downward under the action of gravity. After opening, the connecting cylinder continues to push the upper hot plate 28 to slide down and contact the lower sidewall connecting cover 3. The tread block 15 is stressed and shrinks inward until the fit is completed, and vulcanization is carried out under high pressure and high temperature.

[0060] After the vulcanization time is over, the stroke adjustment device 103 is self-locked by the self-locking device 12, the connecting cylinder moves upward, and drives the die sleeve large ring 13 to move upward through the upper hot plate 28. At this time, the pattern block 15 opens downward under the influence of gravity. When it reaches the specified position, the active mold connecting cylinder 104 is energized, and the active mold connecting cylinder 104 exerts an upward pulling force on the active mold driving connector 18, and the pattern block 15 contracts until it reaches the specified position and stops in time;

[0061] The present invention adopts a split structure. The mold and the center mechanism 26 are connected by a positioning piece 30. The positioning piece 30 is located in the sink groove of the lower hot plate. There is a clearance fit between the inner wall of the positioning piece 30 and the outer circle size of the center mechanism 26. When the mold is placed on the vulcanizer as a whole, the lower sidewall connecting cover 3 is matched with it to achieve preliminary positioning. At the same time, the positioning piece 30 can avoid damage to the center mechanism 26. At the same time, the upper hot plate and the large ring of the mold sleeve are connected by bolts to achieve the positioning of the upper mold. At the same time, the lower sidewall connecting cover 3 is connected to the center mechanism 26 through the positioning piece 30. When the center mechanism 26 descends, the positioning piece 30 and the lower sidewall connecting cover 3 are adapted to each other. During the descent, the lower sidewall connecting cover 3 is concentric under the action of the clamp force to achieve final positioning. The above can effectively reduce the influence of external factors on the connection accuracy, thereby improving the positioning accuracy between the mold and the center mechanism 26 and ensuring the accurate size of the tire cavity.

[0062] The mold design of the present invention is a universal modular structure. The pattern cavity 152 is adapted to the size of the guide side block 151. The pattern cavity only needs to be processed according to the outer diameter size and the matching size to achieve patterns of different specifications and interchangeable assembly. The pattern block is cut into 8 equal parts as a whole. When different patterns are required, the interchange can be achieved by replacing pattern blocks of different patterns. At the same time, the upper cavity sidewall and the lower cavity sidewall are processed according to the size of the upper sidewall connecting cover and the lower sidewall connecting cover 3, so that they can be interchanged. This design can not only greatly reduce the cost of the mold, but also shorten the production cycle and improve production efficiency.

[0063] When the upper and lower mold surfaces of a traditional vulcanizer are preheated, the heat is transferred to the pattern block through heat conduction, which results in a time-consuming and uneven temperature field for the overall mold temperature to reach the required level. The mold of the present invention is provided with a vulcanizing medium channel, and the coverability structure is improved. The inner cavity of the mold sleeve is a steam chamber. The vulcanizing medium can enter the steam chamber through a metal hose to heat the pattern block, effectively reducing the preheating time, while reducing the temperature difference of the overall mold structure and improving product quality. This design can effectively improve the thermal conductivity of the mold, shorten the vulcanization time, increase production, and reduce energy consumption costs.

[0064] In the mold of the present invention, since the pattern blocks are assembled, in addition to being provided with traditional air holes, the assembled type can effectively exhaust the tire blank during the mold closing process and the extrusion process from the outside to the inside. The pattern is pieced together piece by piece, and there are corresponding gaps, which also achieves the exhaust function and can effectively prevent the exhaust holes from being blocked, thereby improving the exhaust effect and improving product quality.

[0065] In general, compared with the prior art, the present invention has higher positioning accuracy, better interchangeability, higher thermal conductivity and better exhaust effect, thereby improving product quality and production efficiency and reducing production costs.

[0066] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes to a tire production mold and its inventive concept according to the technology of the present invention, which should be covered by the protection scope of the present invention.
