Description

Technical Field

[0001] This utility model relates to the field of tire molding mold technology that facilitates demolding, and in particular to a tire molding mold that facilitates demolding. Background Technology

[0002] In the development of the tire manufacturing industry, the demolding process, as a crucial final step in the tire molding process, directly impacts the quality of the finished tire and production efficiency with its smoothness and precision. As the automotive industry continues to demand higher tire performance, tire structural designs are becoming increasingly complex, and the precision requirements for details such as tread patterns and sidewall shapes are becoming more stringent. This poses a greater challenge to the performance of demolding components.

[0003] Traditional tire molding mold demolding methods have many problems that urgently need to be solved. Among them, the susceptibility of tires to damage during demolding is a prominent pain point that has long plagued the industry. Early demolding mechanisms mostly used unidirectional pushing or pulling forces to achieve demolding. For example, some molds only applied upward pushing force through the bottom ejector pin to force the tire to separate from the lower mold. This unidirectional force demolding method causes significant stress concentration in localized areas of the tire at the moment of separation from the mold. For tires with complex structures, especially those with deep tread grooves or special sidewall designs, stress concentration points are highly susceptible to damage such as tread deformation and sidewall tearing.

[0004] Traditional demolding components have low motion precision, often resulting in jamming or displacement deviations during demolding. Inaccurate contact between the demolding mechanism and the tire not only exacerbates localized stress on the tire but can also cause tilting or collisions during demolding, further increasing the risk of surface scratches and internal structural damage. The optimal demolding force varies significantly for tires of different sizes and rubber compounds, making fixed demolding patterns unsuitable for diverse production needs and further amplifying the possibility of tire damage. Therefore, a tire molding die designed for easy demolding is proposed to address these issues. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a tire molding die that facilitates demolding. It solves the problem that when the contact position between the demolding mechanism and the tire is inaccurate, it not only exacerbates the local stress on the tire but may also cause the tire to tilt or collide during demolding, further increasing the risk of tire surface scratches and internal structural damage. For tires of different sizes and with different rubber compounds, the required optimal demolding force varies significantly. Fixed demolding operations are difficult to adapt to diverse production needs, further amplifying the possibility of tire damage.

[0006] To solve the above technical problems, the present invention provides the following technical solution: a tire molding mold that is easy to demold, including a receiving base frame, the receiving base frame being provided with a connecting mechanism, the connecting mechanism including a traction component disposed on the top of the receiving base frame, a demolding component being connected to the front end of the traction component, and a pressing mold component being connected to both sides of the demolding component; The demolding assembly includes a cylinder.

[0009] A further improvement is that the cylinder is fixedly installed on the top middle section of the traction frame, the traction slider is slidably connected to the inner wall of the limiting slide opening at the front section of the traction frame, the spiral rod is rotatably connected to the middle section of the inner wall of the limiting slide opening of the traction frame, and the connecting slide rod is fixedly connected to both sides of the inner wall of the limiting slide opening of the traction frame.

[0010] A further improvement is that the inner wall of the traction frame is slidably connected to the outer wall of the fixed slide rod, and the fixed slide rod is symmetrically arranged on both sides of the inner wall of the upright frame; the fixed slide rods fixedly connected to the inner walls on both sides of the upright frame play a strict guiding role for the traction frame threaded to the outer wall of the threaded push rod, and the traction frame can only slide vertically along the fixed slide rod.

[0011] A further improvement is that the compression molding assembly is symmetrically arranged on both sides of the base frame; the mounting plate fixedly connected to the top of the connecting frame provides a stable mounting platform for the air rod. After the air rod, which is fixedly installed on the inner side of the mounting plate, is started, one end of its inner side pushes the semi-circular template to move towards the center of the mold, thereby pressing and shaping the tire semi-finished product.

The symmetrical arrangement of the pressing assembly ensures uniform force during tire molding, reducing demolding damage caused by structural defects. The synergistic effect of these three components significantly reduces the tire scrap rate and substantially improves the appearance integrity and structural stability of the finished product.

[0014] 2. This utility model achieves fully automated operation from tire forming to demolding through automated position scheduling of the traction component, mechanized collaborative demolding of the demolding component, and synchronous motion control of the compression molding component. Precise tire shaping and smooth demolding can be completed without manual intervention, reducing the time cost of manual operation and avoiding the safety hazards of high-temperature operations. The stable operation of each component reduces the frequency of downtime due to malfunctions, further improving the continuous operating efficiency of the production line and providing strong support for large-scale production.

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.

[0019] Example 1

[0020] When the contact position between the demolding mechanism and the tire is inaccurate, it not only exacerbates the localized stress on the tire but may also cause the tire to tilt or collide during demolding, further increasing the risk of surface scratches and internal structural damage. The optimal demolding force required varies significantly for tires of different sizes and rubber compounds. Fixed demolding patterns are difficult to adapt to diverse production needs, further amplifying the possibility of tire damage. This embodiment provides a tire molding die that facilitates demolding. Please refer to... Figures 1-5The embodiment provides a tire molding die for easy demolding, including a receiving base frame 1, a connecting mechanism 2, and a traction component 21 disposed on the top of the receiving base frame 1. A demolding component 22 is connected to the front of the traction component 21, and molding components 23 are connected to both sides of the demolding component 22. The demolding component 22 includes a cylinder 221, a push rod 222 fixedly connected to one output end of the cylinder 221, a traction slider 223 fixedly connected to the outer wall of the front end of the push rod 222, a spiral rod 224 spirally connected to the inner wall of the middle section of the traction slider 223, a stop block 225 threadedly connected to the outer wall of the spiral rod 224, and connecting slide rods 226 slidably connected to the inner walls of both sides of the traction slider 223. The bottom of the traction slider 223... A connecting rod 227 is fixedly connected, and an upper ejector plate 228 is fixedly connected to the bottom of the connecting rod 227. A base frame 229 is set at the front end of one side of the receiving base frame 1. An adjusting motor 2210 is fixedly installed on the outer wall of one side of the front of the base frame 229. A rotating shaft 2211 is fixedly connected to the output end of one side of the adjusting motor 2210. A bevel gear 1 2212 is fixedly connected to the outer wall of the rotating shaft 2211. A bevel gear 2213 meshes with the top of the bevel gear 1 2212. A drive shaft 2214 is fixedly connected to the inner wall of the bevel gear 2213. A gear 2215 is fixedly connected to the outer wall of the upper section of the drive shaft 2214. A rack and pinion slide 2216 meshes with the outer walls of the front and rear ends of the gear 2215. A lower ejector plate 2217 is fixedly connected to the top of the outer end of the rack and pinion slide 2216.

[0021] In this embodiment, the demolding assembly 22 is the core component that solves the problem of tire damage during traditional demolding. Through multi-directional coordinated force and high-precision movement, it achieves smooth and safe demolding of the tire. After the cylinder 221, which is fixedly installed in the middle of the top of the traction frame 217, is started, its output end at one front end pushes the push rod 222 forward. The traction slider 223, which is fixedly connected to the outer wall of the front end of the push rod 222, slides on the inner wall of the limiting slide opening at the front of the traction frame 217. The spiral rod 224, which is spirally connected to the inner wall of the middle section of the traction slider 223, can... By precisely adjusting the position of the traction slider 223 through rotation, and in conjunction with the stop block 225, its movement range can be strictly limited, avoiding the squeezing or pulling damage to the tire caused by excessive or insufficient movement in traditional demolding mechanisms. Simultaneously, the inner walls on both sides of the traction slider 223 slide on the connecting slide rod 226, further enhancing the smoothness of movement and preventing excessive localized stress on the tire due to movement jamming. As the traction slider 223 moves, the connecting rod 227 fixedly connected to its bottom drives the upper demolding plate 228 to move downwards, applying uniform force from above the tire. A uniform force is applied; simultaneously, the adjusting motor 2210 on the outer wall of one end of the front of the base frame 229 is activated, and the rotating shaft 2211 at the output end of its rear end rotates, causing the bevel gear 2212 fixedly connected to the outer wall of the rotating shaft 2211 to rotate accordingly, thereby driving the bevel gear 2213 meshing with the top of the bevel gear 2212 and the transmission shaft 2214 to rotate; the gear 2215 fixedly connected to the outer wall of the upper section of the transmission shaft 2214 rotates, driving the rack and pinion slide 2216 meshing with the front and rear outer walls of the gear 2215 to open the limit on the top of the base frame 229. As the inner wall of the groove slides outward, the lower ejector plate 2217 at the top of the outer end of the rack slide plate 2216 moves outward accordingly, applying force from both sides below the tire. The coordinated movement of the upper ejector plate 228 and the lower ejector plate 2217 changes the traditional single-direction force pattern, making the tire evenly stressed during the demolding process, effectively avoiding problems such as tread deformation and sidewall tearing caused by stress concentration. Moreover, the precise motion control of each component reduces the tilting and collision of the tire during the demolding process, reducing the risk of surface scratches and internal structural damage.

[0022] Furthermore, cylinder 221 is fixedly installed on the top middle section of traction frame 217, traction slider 223 is slidably connected to the inner wall of the limiting slide opening at the front section of traction frame 217, spiral rod 224 is rotatably connected to the middle section of the inner wall of the limiting slide opening of traction frame 217, and connecting slide rod 226 is fixedly connected to both sides of the inner wall of the limiting slide opening of traction frame 217; rotating shaft 2211 is rotatably connected to base frame 229, transmission shaft 2214 is rotatably connected to base frame 229, rack and pinion slide plate 2216 is slidably connected to the bottom of the limiting slide groove opening at the top of base frame 229, and lower ejection template 2217 is slidably connected to the bottom of the top of base frame 229.

[0023] Furthermore, the adjustment motor 2210 on the outer wall of the front end of the base frame 229 is started, and the rotating shaft 2211 at the output end of the back end rotates, causing the bevel gear 2212 fixedly connected to the outer wall of the rotating shaft 2211 to rotate, thereby driving the bevel gear 2213 and the transmission shaft 2214 that mesh with the top of the bevel gear 2212 to rotate.

[0024] Example 2

[0025] Based on Embodiment 1, the traction assembly 21 includes a rotating motor 211 fixedly installed on the inner wall of the top of the receiving base frame 1. The top output end of the rotating motor 211 is fixedly connected to a turntable 212. The top middle section of the turntable 212 is fixedly connected to a stand 213. The top middle section of the stand 213 is fixedly installed with a drive motor 214. The bottom output end of the drive motor 214 is fixedly connected to a threaded push rod 215. The inner walls on both sides of the stand 213 are fixedly connected with fixed slide rods 216. The outer wall of the threaded push rod 215 is threadedly connected with a traction frame 217. The molding assembly 23 includes a connecting frame 231. The top of the connecting frame 231 is fixedly connected to a mounting plate 232. The inner side of the mounting plate 232 is fixedly installed with a pneumatic rod 233. One end of the inner side of the pneumatic rod 233 is fixedly connected to a semi-circular template 234.

[0026] In this embodiment, the traction component 21 is the "dispatch center" of the entire mold system, providing precise positional support for demolding and pressing operations. After the rotating motor 211, fixedly installed on the inner wall of the top of the receiving base 1, starts, its top output end drives the turntable 212 to rotate, thereby causing the upright frame 213 in the middle of the top of the turntable 212 to rotate accordingly. This allows for flexible adjustment of the upright frame 213 in the horizontal direction, enabling precise positioning of subsequent working parts to appropriate horizontal positions according to different stages and requirements of tire molding. When the drive motor 214 in the middle of the top of the upright frame 213 starts, the threaded push rod 215 connected to its bottom output end begins to rotate. Because the fixed sliding rods 216 fixedly connected to the inner walls on both sides of the upright frame 213 provide strict guidance for the traction frame 217 threadedly connected to the outer wall of the threaded push rod 215, the traction frame 217 can only slide vertically up and down along the fixed sliding rods 216. This design avoids component collisions or incomplete operations caused by positional adjustment deviations in traditional equipment, ensuring that the traction frame 217 moves vertically. The precise positioning of the components provides a stable and accurate working reference for the demolding assembly 22 and the compression mold assembly 23, reducing potential damage to the tire due to inaccurate positioning from the outset. The compression mold assembly 23 is symmetrically arranged on both sides of the base frame 229, playing an important role in the tire molding stage and laying a good foundation for smooth demolding. The mounting plate 232, which is fixedly connected to the top of the connecting frame 231, provides a stable mounting platform for the air rod 233. After the air rod 233, which is fixedly installed on the inner side of the mounting plate 232, is activated, one end of its inner side pushes the semi-circular template 234 towards the center of the mold to press and shape the semi-finished tire. Due to the symmetrical arrangement of the compression mold assembly 23, uniform pressure can be applied from both sides of the tire, ensuring that the force on each part of the tire is consistent during the molding process, avoiding tire structural defects caused by uneven force, and reducing the risk of damage caused by the tire's own structural problems during demolding. During the demolding stage, the air rod 233 drives the semi-circular template 234 to return to its original position in time, without hindering the operation of the demolding assembly 22, ensuring the smoothness of the demolding process.

[0027] Furthermore, the inner wall of the traction frame 217 is slidably connected to the outer wall of the fixed slide rod 216, and the fixed slide rod 216 is symmetrically arranged on both sides of the inner wall of the upright frame 213; the molding assembly 23 is symmetrically arranged on both sides of the base frame 229.

[0028] Furthermore, the fixed sliding rods 216, which are fixedly connected to the inner walls on both sides of the upright frame 213, play a strict guiding role for the traction frame 217, which is threadedly connected to the outer wall of the threaded push rod 215. The traction frame 217 can only slide vertically up and down along the fixed sliding rods 216. This design avoids the situation of component collision or improper operation caused by position adjustment deviation in traditional equipment, and ensures the accuracy of the vertical movement of the traction frame 217. It provides a stable and accurate working reference for the demolding assembly 22 and the pressing assembly 23, and reduces the potential damage to the tires caused by inaccurate positioning from the source.

[0029] Working principle: The traction component 21 is the "dispatch center" of the entire mold system, providing precise positional support for demolding and pressing operations; after the rotary motor 211, which is fixedly installed on the inner wall of the top of the supporting base 1, is started, its top output end drives the turntable 212 to perform circular motion, thereby causing the upright frame 213 in the middle of the top of the turntable 212 to rotate accordingly, realizing flexible adjustment of the upright frame 213 in the horizontal direction. It can accurately position the subsequent working parts to the appropriate horizontal position according to different stages and needs of tire molding; when the drive motor 214 in the middle of the top of the upright frame 213 is started, the screw connected to its bottom output end... The threaded push rod 215 begins to rotate; because the fixed slide rods 216 fixedly connected to the inner walls on both sides of the upright frame 213 provide a strict guiding effect on the traction frame 217 threadedly connected to the outer wall of the threaded push rod 215, the traction frame 217 can only slide vertically up and down along the fixed slide rods 216; this design avoids the situation of component collision or operation failure caused by position adjustment deviation in traditional equipment, ensures the accuracy of the traction frame 217 moving in the vertical direction, and provides a stable and accurate working reference for the demolding assembly 22 and the pressing assembly 23, reducing the potential damage to the tires caused by inaccurate positioning from the source; The demolding assembly 22 is a core component that solves the problem of tire damage during traditional demolding processes. Through multi-directional coordinated force and high-precision movement, it achieves smooth and safe demolding of the tire. After the cylinder 221, which is fixedly installed in the middle of the top of the traction frame 217, is started, its output end pushes the push rod 222 forward. The traction slider 223, which is fixedly connected to the outer wall of the front end of the push rod 222, slides on the inner wall of the limiting slide opening at the front of the traction frame 217. The spiral rod 224, which is spirally connected to the inner wall of the middle section of the traction slider 223, can be rotated to achieve precise... The position of the traction slider 223 is precisely adjusted, and its movement range is strictly limited by the stop block 225, avoiding the squeezing or pulling damage to the tire caused by excessive or insufficient movement in traditional demolding mechanisms. At the same time, the inner walls on both sides of the traction slider 223 slide on the connecting slide rod 226, which further enhances the stability of movement and prevents excessive local stress on the tire caused by movement jamming. As the traction slider 223 moves, the connecting rod 227 fixedly connected to its bottom drives the upper demolding plate 228 to move downward, applying a uniform force from above the tire. At the same time, the adjustment motor 2210 on the outer wall of one end of the front of the base frame 229 is started, and the rotating shaft 2211 at the output end of the rear end of the motor rotates, causing the bevel gear 2212 fixedly connected to the outer wall of the rotating shaft 2211 to rotate, which in turn drives the bevel gear 2213 meshing with the top of the bevel gear 2212 and the drive shaft 2214 to rotate; the gear 2215 fixedly connected to the outer wall of the upper section of the drive shaft 2214 rotates, driving the rack slide plate 2216 meshing with the front and rear outer walls of the gear 2215 to limit the sliding plate opened on the top of the base frame 229. As the inner wall of the groove slides outward, the lower ejector plate 2217 at the top of the outer end of the rack slide plate 2216 moves outward accordingly, applying force from both sides below the tire. The coordinated movement of the upper ejector plate 228 and the lower ejector plate 2217 changes the traditional single-direction force pattern, making the tire evenly stressed during the demolding process, effectively avoiding problems such as tread deformation and sidewall tearing caused by stress concentration. Moreover, the precise motion control of each component reduces the tilting and collision of the tire during the demolding process, reducing the risk of surface scratches and internal structural damage. The compression molding assembly 23 is symmetrically arranged on both sides of the base frame 229, playing an important role in the tire molding stage and laying a good foundation for smooth demolding. The mounting plate 232, which is fixedly connected to the top of the connecting frame 231, provides a stable mounting platform for the air rod 233. After the air rod 233, which is fixedly installed on the inner side of the mounting plate 232, is activated, one end of its inner side pushes the semi-circular template 234 towards the center of the mold to press and shape the tire semi-finished product. Due to the symmetrical arrangement of the compression molding assembly 23, uniform pressure can be applied from both sides of the tire, ensuring that the force on each part of the tire is consistent during the molding process, avoiding tire structural defects caused by uneven force, and reducing the risk of damage caused by the tire's own structural problems during demolding. During the demolding stage, the air rod 233 drives the semi-circular template 234 to return to its original position in time, without hindering the operation of the demolding assembly 22, ensuring the smoothness of the demolding process. The precise control of the traction component 21, the coordinated demolding of the demolding component 22, and the stable shaping of the compression molding component 23 work together to form an efficient, precise, and safe tire molding and demolding system. This effectively solves the problems of traditional molds and significantly improves the quality and efficiency of tire production.
