Description

Technical Field

[0001] This invention belongs to the field of rubber track vulcanization molding technology, specifically a rubber track one-time vulcanization molding equipment. Background Technology

[0002] Rubber tracks are ring-shaped transmission components made of rubber and metal composite materials. Compared with metal tracks, they have advantages such as light weight, less damage to the road surface, low driving noise, and corrosion resistance, and are widely used in agricultural machinery and engineering machinery.

[0003] The vulcanization molding process of rubber tracks typically involves bonding and arranging the mixed rubber, steel cord, and canvas as skeleton materials on a track forming machine according to design requirements to form an unvulcanized semi-finished product. The semi-finished product is then placed into a vulcanization mold. After the mold is closed, heating and pressure are applied to cause the rubber molecules to undergo a cross-linking reaction, while simultaneously ensuring that the rubber and skeleton materials are tightly bonded together to form the preset patterns and tooth shapes. After vulcanization at the set time and temperature, the mold is opened, the finished product is removed, cooled, trimmed, and inspected.

[0004] Traditional rubber track vulcanization molding equipment mainly refers to frame vulcanizing machines. Its main body is composed of upper and lower crossbeams and columns welded from high-strength cast iron. It is equipped with heated upper and lower molds and a hydraulic structure. During operation, the hydraulic cylinder pushes the movable platform to close the mold. The mold cavity reaches the vulcanization temperature through electric heating. At the same time, the hydraulic structure continuously provides mold closing pressure to overcome the internal expansion force of the rubber and ensure the product is dense.

[0005] In the traditional vulcanization process of rubber tracks, in order to adapt to the special shape of the annular rubber track, the equipment usually adopts a segmented vulcanization process. This is a process in which the entire flattened annular rubber track is divided into two halves and vulcanized separately. First, one half is vulcanized and formed, and then the formed half is rotated and vulcanized again. This means that two vulcanization processes are required to form the annular rubber track. Because segmented vulcanization is required, and the half of the rubber track needs to be fed and its position adjusted each time, this not only increases the number of operation steps, but also prolongs the overall vulcanization time.

[0006] Therefore, the present invention provides a rubber track vulcanization molding equipment. Summary of the Invention

[0018] The beneficial effects of this invention are as follows: 1. The present invention discloses a one-time vulcanization molding equipment for rubber tracks, which uses a vulcanizing frame as the main frame, a slide rail frame fixed at the bottom of the frame to support the sliding of an electric slide frame, the electric slide frame connected to an upper mold via a hydraulic cylinder, a lower base plate as the bottom support, and an annular mold fixed on the lower base plate for rubber track vulcanization. The transmission component first drives two square slide molds and four arc-shaped slide molds to approach the annular mold, reducing the gap, placing the semi-finished rubber track into the gap and positioning it. The electric slide frame drives the upper mold to move above the annular mold, and the hydraulic cylinder pushes the upper mold to press against the annular mold and slide molds. The transmission component again drives the slide molds to close the mold, and electric heating makes the inner cavity of the mold reach the vulcanization temperature and continuously provides mold closing pressure. One constant temperature and pressure vulcanization can form the track. After vulcanization, the hydraulic cylinder lifts the upper mold, and the transmission component drives the slide molds to exit, and the finished product is removed. The present invention improves the existing equipment, requiring only one mold closing vulcanization, replacing the segmented operation method, reducing steps and shortening the total time, and improving production efficiency. At the same time, the small gap formed by the slide molds approaching the annular mold can limit the semi-finished product and prevent it from tilting and falling.

[0019] 2. The rubber track vulcanization molding equipment of the present invention performs demolding in stages. In the first stage, an electric multi-way valve controls the No. 2 air pump to connect with two No. 2 cylinders, driving the side support blocks to open both ends of the rubber track. In the second stage, the No. 2 cylinder is closed and pressure is maintained, while the No. 2 air pump is connected with eight No. 3 cylinders, causing the No. 3 cylinders to push the ejector plate to open both sides of the rubber track. By opening the track evenly in stages, the sides are avoided from still tightly gripping the mold when only the two ends are opened, which reduces the tightness of the fit. This makes the demolding force more uniform, reduces local tensile deformation, and ensures the quality of the finished product. After the entire track is opened, it moves with the upper mold to complete the unloading. After demolding is completed, the No. 2 air pump evacuates the No. 3 and No. 2 cylinders, causing the ejector plate and side support blocks to retract and reset, ready for the next operation.

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 12As shown in the embodiment of the present invention, a rubber track vulcanization molding equipment includes a vulcanizing frame 1; a slide rail frame 11 is fixedly connected to the vulcanizing frame 1; an electric slide frame 12 is slidably connected to the slide rail frame 11; a hydraulic cylinder 13 is fixedly connected to the bottom end of the electric slide frame 12; an upper mold 14 is fixedly connected to the bottom end of the hydraulic cylinder 13; a lower base plate 15 is fixedly connected to the bottom of the vulcanizing frame 1, and the lower base plate 15 corresponds to the upper mold 14; an annular mold 16 is fixedly connected to the lower base plate 15; two square slide molds 17 are slidably connected to the lower base plate 15, and the two square slide molds 17 are arranged opposite each other; two arc-shaped slide molds 18 are slidably connected to both sides of the lower base plate 15 near the square slide molds 17, and four arc-shaped slide molds 18 are arranged in pairs opposite each other; a transmission assembly is provided on the lower base plate 15, and the transmission assembly is used to drive the two square slide molds 17 and the four arc-shaped slide molds 18 to slide and close the mold.During the one-time vulcanization molding of the rubber track, the vulcanizing frame 1 serves as the main frame of the molding equipment. The slide rail frame 11 is fixed to the bottom of the vulcanizing frame 1, supporting the sliding of the electric slide frame 12. The electric slide frame 12 is connected to the upper mold 14 through the hydraulic cylinder 13. The lower base plate 15 serves as the bottom support of the vulcanizing mold. The annular mold 16 is fixed on the lower base plate 15 for use in the vulcanization molding of the rubber track. The lower base plate 15, the annular mold 16, the square slide mold 17, and the arc slide mold 18 constitute the lower mold. The transmission component first drives the two square slide molds 17 and the four arc slide molds 18 to slide. Approaching the annular mold 16, the gap between them is reduced. Then, the worker neatly places the semi-finished rubber track within the gap, ensuring the track aligns with the holes in the annular mold 16. The electric slide 12 then drives the hydraulic cylinder 13 and the upper mold 14 to slide above the annular mold 16. The output end of the hydraulic cylinder 13 extends downwards, causing the upper mold 14 to press against the annular mold 16, two square sliding molds 17, and four arc-shaped sliding molds 18. Subsequently, the transmission assembly again drives the two square sliding molds 17 and four arc-shaped sliding molds 18 to slide... The dynamic mold closing process compresses the semi-finished rubber track tightly against the annular mold 16, facilitating subsequent vulcanization molding of the semi-finished rubber track. Electric heating raises the mold cavity to the vulcanization temperature while continuously providing closing pressure to overcome the internal expansion force of the rubber and ensure product density. A single constant-temperature, high-pressure vulcanization process completes the molding of the entire annular rubber track. After vulcanization, the hydraulic cylinder 13 lifts and resets the upper mold 14, and the transmission assembly then drives the two square sliding molds 17 and four arc-shaped sliding molds 18 to slide out in the opposite direction, thus completing the molding process. After molding, the rubber track is taken out of the equipment. This embodiment of the invention addresses the technical pain points of existing vulcanization molding equipment, such as cumbersome procedures, long production cycles, and low operating efficiency, by optimizing and improving the structure and process. It abandons the traditional multi-stage step-by-step molding operation mode of mold closing and step-by-step vulcanization. The rubber track can be vulcanized and molded as a whole by only one mold closing and vulcanization, which replaces the traditional step-by-step vulcanization molding method. It saves redundant operation steps such as multiple mold opening and closing, segmented pressurization, and step-by-step vulcanization, shortens the total vulcanization time, and thus improves the production efficiency of rubber tracks. At the same time, when the transmission component drives the two square sliding molds 17 and the four arc sliding molds 18 to slide close to the annular mold 16, the resulting small gap can limit the loading of the semi-finished rubber track, reducing the possibility of the semi-finished rubber track tilting and falling after being placed in the small gap.

[0025] The transmission assembly includes a first air pump 2, a first cylinder 21, and a sliding seat 22; the first air pump 2 is fixedly connected to the lower base plate 15; multiple first cylinders 21 are connected to the output end of the first air pump 2 through short pipes of different lengths; two square sliding molds 17 and four arc-shaped sliding molds 18 are respectively fixedly connected to multiple first cylinders 21; the sliding seat 22 is fixedly connected to the output end of the first cylinder 21; a second air pump 3 is fixedly connected to the upper mold 14; Both output ends of the second air pump 3 are fixedly connected to an electric multi-way valve 31; one end of the electric multi-way valve 31 is fixedly connected to a second cylinder 32; the output end of the second cylinder 32 is fixedly connected to a side support block 33, and the two side support blocks 33 are respectively located at both ends of the upper mold 14; the second air pump 3 has four output ends, and two of the output ends are fixedly connected to two third cylinders 4, and two third cylinders 4 are fixedly connected to the electric multi-way valve 31. Two No. 3 cylinders 4 are located on both sides of No. 2 cylinder 32; the output ends of all eight No. 3 cylinders 4 are fixedly connected to ejector plates 41; when controlling the sliding of the two square sliding molds 17 and the four arc-shaped sliding molds 18, the No. 1 air pump 2 is fixed on the lower base plate 15 and connected to multiple No. 1 cylinders 21. The multiple No. 1 cylinders 21 are connected to multiple sliding seats 22 through multiple short pipes of different lengths. After the No. 1 air pump 2 works to draw air into the multiple No. 1 cylinders 21, the output ends of the multiple No. 1 cylinders 21 retract, causing the connected sliding seats 22 to slide. The two square sliding molds 17 and the four arc-shaped sliding molds 18 connected to the multiple sliding seats 22 slide synchronously closer together, which plays the role of closing the mold; when the No. 1 air pump 2 works to pump air in the opposite direction, the output ends of the multiple No. 1 cylinders 21 extend, and the sliding seats 22 also slide with the output ends of the No. 1 cylinders 21, which can make the two square sliding molds 17 and the four arc-shaped sliding molds 18 slide away synchronously, which plays the role of demolding. Before the rubber track formed by vulcanization is demolded from the annular mold 16, the two side support blocks 33 are inserted into the two ends of the annular mold 16 as the upper mold 14 is pressed together. During demolding, the two side support blocks 33 located inside the two ends of the annular mold 16 can slide in opposite directions. The second air pump 3 is fixed on the upper mold 14 to control the air supply and extraction in the two second air cylinders 32. The electric multi-way valve 31 controls the air passage between the second air pump 3 and the second air cylinder 32. The electric multi-way valve 31 first connects the second air pump 3 and the second air cylinder 32. The working pump air of the second air pump 3 reaches the second air cylinder 32 through the electric multi-way valve 31, causing the output end of the second air cylinder 32 to drive the side support blocks 33 to slide. At this time, the two side support blocks 33 3 can slide out from both ends of the annular mold 16 and open up both ends of the rubber track after vulcanization, so that the two ends of the vulcanized rubber track can quickly separate from the annular mold 16. Then, with the help of manual labor, the two sides of the rubber track can be separated from the annular mold 16, which can reduce the situation where the two ends of the rubber track are tightly stuck on the annular mold 16 after vulcanization and are difficult to demold, and improve the smoothness of demolding. Then, the electric slide 12 drives the rubber track that has been opened and demolded at the bottom of the upper mold 14 to slide to the unloading point, realizing the demolding and unloading of the rubber track. After demolding is completed, the second air pump 3 reverses the air, drives the output end of the second cylinder 32 to retract, and resets the two side support blocks 33 to the initial position, without affecting the subsequent mold closing and vulcanization operation. When the vulcanized rubber track is demolded, in the first stage, the electric multi-way valve 31 first controls the connection between the second air pump 3 and the second cylinder 32. The second air pump 3 can currently only pump air into two cylinders 32, causing the two side support blocks 33 to slide and open the two ends of the rubber track. In the second stage, the electric multi-way valve 31 then closes the connection between the second cylinder 32 and the second air pump 3, maintaining pressure in the second cylinder 32. The electric multi-way valve 31 then opens the connection between the third cylinder 4 and the second air pump 3. At this time, all eight third cylinders 4 are connected to the second air pump 3, and the second air pump 3 pumps air into all eight third cylinders 4, causing the output end of the third cylinder 4 to drive the ejector plate 41 to slide and open the two sides of the rubber track. It should be noted that multiple side support blocks 33 and the ejector plate 41... The ejector plate 41 can be inserted into the annular mold 16 without affecting the one-time vulcanization molding of the rubber track. Through phased demolding, the rubber track is evenly spread out from the inside, reducing the situation where the sides are still tightly held on the annular mold 16 when only the two ends are spread. This reduces the tightness of the fit between the rubber track and the annular mold 16, making the force more even throughout the demolding process. It also reduces the probability of local stretching and deformation of the rubber track during demolding, ensuring the quality of the finished rubber track after demolding. After the overall spreading and demolding is completed, the track moves with the upper mold 14 to complete the unloading. After the demolding operation is completed, the second air pump 3 draws air from the third air cylinder 4 and the second air cylinder 32, causing the ejector plate 41 and the side support block 33 to retract and reset, waiting for the next demolding operation.

[0026] The ejector plate 41 has a groove at one end away from the cylinder 4; an anti-detachment plate 5 is slidably connected to the groove of the ejector plate 41; an elastic element is fixedly connected between the anti-detachment plate 5 and the ejector plate 41; when multiple ejector plates 41 are opened from the inside of the rubber track, as the output end of the cylinder 4 extends, the annular rubber track can rely on its own elasticity to squeeze the anti-detachment plate 5 and slide it into the groove of the ejector plate 41. The elastic element contracts and is subjected to force, and the annular rubber track can be confined within the groove of the ejector plate 41. This allows the rubber track sidewall to have a buffer space when the ejector plate 41 pushes the rubber track sidewall open, reducing the rigid support and pulling of the rubber at the end of the ejector plate 41 and reducing the risk of local deformation of the rubber track; at the same time, the confinement of the groove can reduce the situation where the rubber track slips off the end of the ejector plate 41 during the opening process, ensuring the stability of the demolding and opening process.

[0027] like Figures 1 to 3 , Figure 5 , Figure 12 As shown, two fixing blocks 51 are fixedly connected to both sides of the upper mold 14; an extrusion slide plate 52 is slidably connected to the fixing block 51 via a fifth elastic element; an annular guide rail 53 is fixedly connected to the bottom of the extrusion slide plate 52; a dual camera 54 is slidably connected to the annular guide rail 53 on the inner ring via a first electric slider, and there are two dual cameras 54, which are arranged opposite each other; when the vulcanized annular rubber track is unloaded, as the output end of the hydraulic cylinder 13 retracts, the upper mold 14 drives the multiple extrusion slide plates 52 on both sides to rise synchronously. The top of the extrusion slide plate 52 presses against the bottom of the slide rail frame 11. As the output end of the hydraulic cylinder 13 continues to retract, the extrusion slide plate 52 is squeezed and slides down onto the fixing block 51, the fifth elastic element is stretched and stressed, and the annular guide rail... Track 53 and two opposing dual cameras 54 also slide down to the vicinity of the vulcanized annular rubber track. The two ends of the dual cameras 54 are at different heights, with one end of the dual cameras 54 facing the outer wall of the annular rubber track, while the other end of the dual cameras 54 is tilted to correspond to the inner wall of the annular rubber track. As the electric slide 12 moves the entire annular rubber track to move and unload, the first electric slider moves the dual cameras 54 to visually inspect the annular rubber track around, thus completing the full circumference inspection of the inner and outer walls of the annular rubber track after demolding. Once defects such as insufficient glue, bulges, or bubbles are found on the molding surface of the rubber track, a signal can be immediately output to terminate the unloading process, reminding the operator to handle the defective track, reducing the flow of unqualified products into subsequent processes, and protecting the appearance quality of the molded parts.

[0028] A connecting plate 55 is fixedly connected to two adjacent extrusion slide plates 52; multiple mounting seats 56 are fixedly connected to the connecting plate 55, and each pair of mounting seats 56 is arranged opposite to each other; a displacement roller 57 is rotatably connected between the two oppositely arranged mounting seats 56; when the output end of the hydraulic cylinder 13 retracts and drives the upper mold 14 to rise, the two extrusion slide plates 52 are connected by a connecting plate 55, and the displacement roller 57 on the connecting plate 55, supported by two opposite mounting seats 56, can first conform to the bottom of the slide rail frame 11. The multiple displacement rollers 57 are fitted to the bottom of the slide rail frame 11 instead of the extrusion slide plate 52. As the electric slide frame 12 drives the annular rubber track to move and unload the material, the multiple displacement rollers 57 can roll along the bottom of the slide rail frame 11. This reduces the friction and wear of the extrusion slide plate 52 on the bottom of the slide rail frame 11 during the unloading process, and makes the unloading process smoother and more stable. It also reduces the occurrence of jamming during the unloading process, ensures the stability of the equipment operation during visual inspection, and ensures the accuracy of defect detection.

[0029] like Figures 1 to 4 , Figures 6 to 8 , Figure 11 As shown, a No. 1 air box 6 is fixedly connected to the outside of the square sliding mold 17; a No. 1 cavity is opened at the end of the square sliding mold 17 away from the No. 1 air box 6, and a No. 1 sliding plate 61 is slidably connected in the No. 1 cavity; multiple No. 1 short rods 62 are fixedly connected in the No. 1 cavity of the square sliding mold 17, and the multiple No. 1 short rods 62 correspond to the holes of the No. 1 sliding plate 61; two through holes 63 are opened on the square sliding mold 17 near the No. 1 air box 6; after the rubber track is formed by vulcanization in one step, the square sliding mold 17 slides away from the annular mold 16 with the sliding seat 22, and a No. 1 counterweight is installed on the No. 1 sliding plate 61. The weight of the No. 1 sliding plate 61 plus the weight of the No. 1 counterweight can keep the square sliding mold 17 stationary during the sliding process. The square sliding mold 17 slides away from the No. 1 sliding plate 61 until the square sliding mold 17 moves away from the No. 1 sliding plate 61. After the square sliding mold 17 slides from one end of the top groove of the first sliding plate 61 to the other end, the gap between the square sliding mold 17 and the first sliding plate 61 widens. At this time, multiple first short rods 62 slide away from the holes of the first sliding plate 61, and the holes of the first sliding plate 61 are opened. The output end of the external air cooler is connected to the first air box 6. The working air of the air cooler enters the interior of the first air box 6. The air is sent to the gap in the first cavity through two through holes 63, and then blown from multiple holes of the first sliding plate 61 onto the formed rubber track. The formed rubber track is cooled by air, allowing the rubber track to cool and set in advance. This reduces the stretching and deformation of the rubber track due to its soft texture during the high-temperature demolding process, further ensuring the molding quality of the rubber track after demolding. It also shortens the waiting time for cooling before demolding and improves the overall processing efficiency.

[0030] A second air box 7 is fixedly connected to the outside of the arc-shaped sliding mold 18; a second cavity is opened at the end of the arc-shaped sliding mold 18 away from the second air box 7, and a second sliding plate 71 is slidably connected inside the second cavity; multiple second short rods 72 are fixedly connected inside the second cavity of the arc-shaped sliding mold 18, and the multiple second short rods 72 correspond to the holes of the second sliding plate 71; when the molded rubber track is cooled and shaped, similar to the ventilation mode at the first sliding plate 61, the arc-shaped sliding mold 18 slides away from the annular mold 16 with the sliding seat 22, and a second counterweight is installed on the second sliding plate 71. The weight of the second sliding plate 71 itself plus the weight of the second counterweight can support the arc-shaped sliding mold 18 during its sliding process. The first part stays in place, and the arc-shaped sliding mold 18 slides away from the second sliding plate 71 until the arc-shaped sliding mold 18 slides from one end of the top groove of the second sliding plate 71 to the other end. At this time, the gap between the arc-shaped sliding mold 18 and the second sliding plate 71 widens. At this time, multiple second short rods 72 slide away from the holes of the second sliding plate 71, and the holes of the second sliding plate 71 are opened. The output end of the external air cooler is connected to the second air box 7. The air cooler blows air into the interior of the second air box 7. The air passes through the second air box 7 and is sent to the gap in the second cavity. Then it blows from the multiple holes of the second sliding plate 71 onto the formed rubber track, which plays a role in cooling and shaping the curved part of the rubber track.

[0031] The square sliding mold 17 has multiple first-curved air holes 8; a third air box 81 is fixedly connected to the side of the square sliding mold 17 near the first air box 6, and the third air box 81 can communicate with the first air box 6; the arc-shaped sliding mold 18 has multiple second-curved air holes 82; a fourth air box 83 is fixedly connected to the side of the arc-shaped sliding mold 18 near the second air box 7, and the fourth air box 83 can communicate with the second air box 7; the top of the annular mold 16 is slidably connected to a guide plate 84 through a second elastic element; when the formed rubber track is demolded from the annular mold 16, it moves with the upper mold 14 and the two side... The support block 33 removes the rubber track, and then the second elastic element, which was originally pressed by the upper mold 14, is reset and slides upward. The external air cooler's ventilation enters the interior of the first air box 6 and the second air box 7 respectively. Some of the air is sent through the third air box 81 and the fourth air box 83 to multiple first curved air holes 8 and second curved air holes 82 and blown out. The air blown out by the multiple first curved air holes 8 and second curved air holes 82 can be guided by the inclined surface of the guide plate 84 to cool and shape the inner side of the rubber track, improve the overall cooling speed of the rubber track, shorten the time required for overall cooling and shaping, and reduce the occurrence of air cooling dead zones.

[0032] The square sliding mold 17 is externally rotatably connected to a gear 9, which is located inside the first air box 6. Inside the first air box 6, two sealing slide plates 91 are slidably connected. A second electric slider is mounted on one sealing slide plate 91 and slidably connected to the square sliding mold 17. The two sealing slide plates 91 are arranged opposite each other. A sealing block 92 is fixedly connected to each sealing slide plate 91. A rack plate 93 is fixedly connected to one end of the sealing slide plate 91 away from the sealing block 92, and the rack plate 93 can mesh with the gear 9. When the connection between the through hole 63 and the third air box 81 is switched, the second electric slider drives one sealing slide plate 91 and the sealing block. When the 92 slides close to the sealing through hole 63, the rack plate 93 on one sealing slide plate 91 can mesh with the gear 9, and simultaneously drive the other rack plate 93 to slide, so that the two sealing slide plates 91 move closer to each other and block the two through holes 63. At this time, the air generated by the external air cooler can be sent to the third air box 81 through the first air box 6. When the second electric slider drives the sealing slide plate 91 to slide in the opposite direction, the two sealing blocks 92 can block the connection between the third air box 81 and the first air box 6, and the two through holes 63 are opened, which plays the role of switching the connection between the through hole 63 and the third air box 81, making it easier to control the separate cooling and shaping of the outer and inner sides of the rubber track.

[0033] Both sides of the square sliding mold 17 are slidably connected to side extension plates 94 via elastic element No. 3, and the end of the side extension plate 94 away from the annular mold 16 is provided with a curved surface; the annular mold 16 is slidably connected to a first limiting block 95 and a second limiting block 96 via elastic element No. 4, and each first limiting block 95 and two second limiting blocks 96 form a group, and four groups are provided on the annular mold 16; when the square sliding mold 17 and the two arc-shaped sliding molds 18 are closed, the two arc-shaped sliding molds 18 are located on both sides of the square sliding mold 17, pressing the curved surfaces of the two side extension plates 94, pressing the two side extension plates 94 into the interior of the square sliding mold 17, the elastic element No. 3 contracts and is subjected to force, and the square sliding mold 17 can slide and close with the two arc-shaped sliding molds 18, ensuring that during the mold closing process... The extrusion effect of the semi-finished rubber track is achieved by installing steel wire cords on the annular mold 16. Multiple steel wire cords are inserted from above the annular mold 16. The first steel wire cord is placed between the first limiting block 95 and the second limiting block 96, and the second steel wire cord is placed between the two second limiting blocks 96. This can limit the placement of the steel wire cords. When the multiple square sliding molds 17 and arc sliding molds 18 are closed, the first limiting block 95 and the second limiting block 96 can be squeezed into the annular mold 16. The fourth elastic element is compressed and subjected to force. After the mold is closed, the limited steel wire cords and the semi-finished rubber can be vulcanized and molded as a whole, reducing the problem of steel wire cord displacement and deviation during vulcanization, and ensuring the structural strength and finished product qualification rate of the rubber track after vulcanization.

[0034] Working process: During the one-time vulcanization molding of the rubber track, the vulcanizing frame 1 serves as the main frame of the molding equipment. The slide rail frame 11 is fixed at the bottom of the vulcanizing frame 1, supporting the sliding of the electric slide frame 12. The electric slide frame 12 is connected to the upper mold 14 through the hydraulic cylinder 13. The lower base plate 15 serves as the bottom support of the vulcanizing mold. The annular mold 16 is fixed on the lower base plate 15 for the vulcanization molding of the rubber track. The lower base plate 15, the annular mold 16, the square slide mold 17, and the arc slide mold 18 constitute the lower mold. The transmission component first drives the two square slide molds 17 and the four arc slide molds 18 to slide closer to the annular mold 16, reducing their proximity to the annular mold. After spacing 16, workers neatly place the semi-finished rubber tracks in the gaps, ensuring the tracks align with the holes in the annular mold 16. The electric slide 12 then drives the hydraulic cylinder 13 and the upper mold 14 to slide above the annular mold 16. The output end of the hydraulic cylinder 13 extends downwards, causing the upper mold 14 to press against the annular mold 16, two square sliding molds 17, and four arc-shaped sliding molds 18. The transmission assembly then drives the two square sliding molds 17 and four arc-shaped sliding molds 18 to slide and close the mold. During this closing process, the semi-finished rubber tracks are pressed tightly against the annular mold 16, facilitating subsequent processing of the semi-finished rubber tracks. The rubber track is vulcanized in one step. Electric heating brings the mold cavity to the vulcanization temperature while continuously applying mold-closing pressure to overcome the internal expansion force of the rubber and ensure the product's density. The entire annular rubber track is formed in one constant-temperature, high-pressure vulcanization cycle. After vulcanization, hydraulic cylinder 13 lifts and resets the upper mold 14. The transmission assembly then drives the two square sliding molds 17 and four arc-shaped sliding molds 18 to slide out in the opposite direction, allowing the formed rubber track to be removed from the equipment. This invention addresses the technical pain points of existing vulcanization molding equipment, such as cumbersome processes, long production cycles, and low operating efficiency, by optimizing the structure and process. The improved process eliminates the traditional multi-stage, step-by-step molding and vulcanization operation mode. The rubber track can be vulcanized and molded as a whole with only one mold closing and vulcanization, replacing the traditional segmented vulcanization method. This eliminates redundant operation steps such as multiple mold opening and closing, segmented pressurization, and step-by-step vulcanization, shortening the total vulcanization time and thus improving the production efficiency of rubber tracks. At the same time, when the transmission component drives the two square sliding molds 17 and four arc-shaped sliding molds 18 to slide close to the annular mold 16, the small gaps created can limit the loading of semi-finished rubber tracks, reducing the possibility of the semi-finished rubber tracks tilting and falling after being placed in the small gaps.When the sliding of the two square sliding molds 17 and the four arc-shaped sliding molds 18 is controlled, the No. 1 air pump 2 is fixed on the lower base plate 15 and connected to multiple No. 1 cylinders 21. The multiple No. 1 cylinders 21 are connected to multiple sliding seats 22 through multiple short pipes of different lengths. After the No. 1 air pump 2 works to draw air into the multiple No. 1 cylinders 21, the output ends of the multiple No. 1 cylinders 21 retract, causing the connected sliding seats 22 to slide. The two square sliding molds 17 and the four arc-shaped sliding molds 18 connected to the multiple sliding seats 22 slide synchronously closer together, which plays the role of closing the mold. When the No. 1 air pump 2 works to pump air in the opposite direction, the output ends of the multiple No. 1 cylinders 21 extend, and the sliding seats 22 also slide with the output ends of the No. 1 cylinders 21, which can make the two square sliding molds 17 and the four arc-shaped sliding molds 18 slide away synchronously, which plays the role of demolding. Before the rubber track, formed by vulcanization in one step, is demolded from the annular mold 16, two side support blocks 33 are inserted into the two ends of the annular mold 16 as the upper mold 14 is pressed together. During demolding, the two side support blocks 33 located inside the two ends of the annular mold 16 can slide in opposite directions. The second air pump 3, fixed on the upper mold 14, controls the air supply and extraction for the two second cylinders 32. The electric multi-way valve 31 controls the air passage between the second air pump 3 and the second cylinder 32. The electric multi-way valve 31 first connects the second air pump 3 and the second cylinder 32. The working air pumped by the second air pump 3 reaches the second cylinder 32 through the electric multi-way valve 31, causing the output end of the second cylinder 32 to drive the side support blocks 33 to slide. At this point, the two side support blocks 33 can slide out from both ends of the annular mold 16, and open up the two ends of the rubber track after vulcanization, so that the two ends of the vulcanized rubber track can quickly detach from the annular mold 16. Then, with the help of manual labor, the two sides of the rubber track can be detached from the annular mold 16, which can reduce the situation where the two ends of the rubber track are tightly stuck on the annular mold 16 after vulcanization and are difficult to demold, and improve the smoothness of demolding. Then, the electric slide 12 drives the rubber track that has been opened and demolded at the bottom of the upper mold 14 to slide to the unloading point, realizing the demolding and unloading of the rubber track. After demolding is completed, the second air pump 3 reverses the air flow, driving the output end of the second cylinder 32 to retract, so that the two side support blocks 33 return to their initial positions. The initial position does not affect subsequent mold closing and vulcanization operations. When the rubber track, formed in one vulcanization, is demolded, in the first stage, the electric multi-way valve 31 first controls the connection between the second air pump 3 and the second cylinder 32. The second air pump 3 can currently only pump air into the two second cylinders 32, causing the two side support blocks 33 to slide and open the two ends of the rubber track. In the second stage, the electric multi-way valve 31 then closes the connection between the second cylinder 32 and the second air pump 3 to maintain pressure in the second cylinder 32. The electric multi-way valve 31 then opens the connection between the third cylinder 4 and the second air pump 3. At this time, all eight third cylinders 4 are connected to the second air pump 3, and the second air pump 3 pumps air into the eight third cylinders 4, causing the output end of the third cylinder 4 to drive... The ejector plate 41 slides to open both sides of the rubber track. Through phased demolding, the rubber track is evenly opened from the inside out, reducing the situation where the sides are still tightly held on the annular mold 16 when only the two ends are opened. This reduces the tightness of the fit between the rubber track and the annular mold 16, making the force more even throughout the demolding process. It also reduces the probability of local stretching and deformation of the rubber track during demolding, ensuring the quality of the finished rubber track after demolding. After the overall opening and demolding are completed, the track moves with the upper mold 14 to complete the unloading. After the demolding operation is completed, the second air pump 3 draws air from the third air cylinder 4 and the second air cylinder 32, causing the ejector plate 41 and the side support block 33 to retract and reset, waiting for the next demolding operation.When multiple ejector plates 41 extend from the inside of the rubber track, as the output end of cylinder 4 extends, the annular rubber track can rely on its own elasticity to squeeze the anti-slip plate 5 and slide it into the groove of the ejector plate 41. The first elastic element contracts and is subjected to force, and the annular rubber track can be confined within the groove of the ejector plate 41. This allows the rubber track sidewall to have a buffer space when the ejector plate 41 pushes the rubber track sidewall open, reducing the rigid support and pulling of the rubber at the end of the ejector plate 41 and reducing the risk of local deformation of the rubber track. At the same time, the confinement of the groove can reduce the situation where the rubber track slips off the end of the ejector plate 41 during the opening process, ensuring the stability of the demolding and opening process. When the vulcanized annular rubber track is unloaded, as the output end of the hydraulic cylinder 13 retracts, the upper mold 14 drives multiple extrusion slide plates 52 on both sides to rise synchronously. The top of the extrusion slide plate 52 presses against the bottom of the slide rail frame 11. As the output end of the hydraulic cylinder 13 continues to retract, the extrusion slide plate 52 is squeezed and slides down onto the fixed block 51. The fifth elastic element is stretched and stressed, and the annular guide rail 53 and the two opposing dual cameras 54 also slide down to the vicinity of the vulcanized annular rubber track. The two ends of the dual cameras 54 are at different heights, and the viewing angle of one end of the dual cameras 54 is directly facing the outer wall of the annular rubber track, while the viewing angle of the other end of the dual cameras 54 is tilted to correspond to the inner wall of the annular rubber track. As the electric slide frame 12 drives the entire annular rubber track to move and unload, the first electric slider drives the dual cameras 54 to visually inspect the annular rubber track around, thereby completing the full circumference inspection of the inner and outer walls of the annular rubber track after demolding. Once a problem is found where there is insufficient glue or bulges on the molding surface of the rubber track, the system will detect the problem. If a bubble defect is detected, a signal can be immediately output to terminate the feeding process, reminding the operator to handle the defective track, reducing the flow of defective products into subsequent processes, and protecting the appearance quality of the molded parts. When the output end of the hydraulic cylinder 13 retracts and drives the upper mold 14 to rise, the two extrusion slide plates 52 are connected by a connecting plate 55. The displacement rollers 57 supported by two opposing mounting seats 56 on the connecting plate 55 can first fit against the bottom of the slide rail frame 11, so that multiple displacement rollers 57 fit against the bottom of the slide rail frame 11 instead of directly fitting against the extrusion slide plates 52. As the electric slide frame 12 drives the annular rubber track to move and feed, multiple displacement rollers 57 can roll along the bottom of the slide rail frame 11, which not only reduces the friction and wear of the extrusion slide plates 52 on the bottom of the slide rail frame 11 during the feeding process, but also makes the feeding process smoother and more stable, reduces the occurrence of jamming during the feeding process, ensures the stability of the equipment operation during visual inspection, and ensures the accuracy of defect detection. After the rubber track is formed by vulcanization, the square sliding mold 17 slides away from the annular mold 16 along with the sliding seat 22. A counterweight is installed on the first sliding plate 61. The weight of the first sliding plate 61 plus the weight of the first counterweight allows the square sliding mold 17 to remain stationary during the sliding process. The square sliding mold 17 slides away from the first sliding plate 61 until it slides from one end of the top groove of the first sliding plate 61 to the other end. At this time, the gap between the square sliding mold 17 and the first sliding plate 61 widens. At this time, multiple first short rods 62 slide away from the holes of the first sliding plate 61, the holes of the first sliding plate 61 are opened, and the output end of the external air cooler is connected to the first air box 6. The air cooler blows air. Entering the interior of the first air box 6, air is delivered through two through holes 63 to the gap in the first cavity, and then blown onto the molded rubber track through multiple holes in the first sliding plate 61. This air-cools the molded rubber track, allowing it to cool and solidify in advance, reducing the risk of stretching and deformation due to its soft texture during high-temperature demolding. This further ensures the molding quality of the rubber track after demolding and also shortens the waiting time for cooling before demolding, improving overall processing efficiency. When the molded rubber track is cooling and solidifying, similar to the ventilation mode at the first sliding plate 61, the arc-shaped sliding mold 18 slides away from the annular mold 16 along with the sliding seat 22. The second sliding plate 71 is equipped with a second counterweight block, and the second sliding plate 71 itself... The weight of the combined weight of the second counterweight allows the arc-shaped sliding mold 18 to initially remain stationary during its sliding motion. The arc-shaped sliding mold 18 then slides away from the second sliding plate 71 until it moves from one end of the top groove of the second sliding plate 71 to the other. At this point, the gap between the arc-shaped sliding mold 18 and the second sliding plate 71 widens. Simultaneously, multiple second-generation short rods 72 slide away from the holes in the second sliding plate 71, opening the holes. The output of the external air cooler connects to the second air box 7, allowing the air cooler to blow air into the interior of the second air box 7. The air then passes through the second air box 7 and is delivered to the gap in the second cavity, subsequently being blown from the multiple holes in the second sliding plate 71 onto the formed rubber track, thus bending the rubber track. The cooling and shaping function: After the formed rubber track is demolded from the annular mold 16, the upper mold 14, together with the two side support blocks 33, takes out the rubber track. Then, the second elastic element, which was originally pressed by the upper mold 14, is elastically squeezed and the guide plate 84 is reset and slid upward. The ventilation of the external air cooler enters the interior of the first air box 6 and the second air box 7 respectively. Some of the air is sent through the third air box 81 and the fourth air box 83 to the multiple first curved air holes 8 and the second curved air holes 82 and blown out. The air blown out by the multiple first curved air holes 8 and the second curved air holes 82 can be guided by the inclined surface of the guide plate 84 to cool and shape the inner side of the rubber track, improve the overall cooling speed of the rubber track, shorten the overall cooling and shaping time, and reduce the occurrence of air cooling dead zones.When the control switches the connection between the through hole 63 and the No. 3 air box 81, the electric slider drives a sealing plate 91 and a sealing block 92 to slide close to the sealing through hole 63. The rack plate 93 on the sealing plate 91 can mesh with the gear 9, and simultaneously drive the other rack plate 93 to slide, so that the two sealing plates 91 move closer to each other and block the two through holes 63. At this time, the air generated by the external air cooler can be sent to the No. 3 air box 81 through the No. 1 air box 6. When the electric slider drives the sealing plate 91 to slide in the opposite direction, the two sealing blocks 92 can block the connection between the No. 3 air box 81 and the No. 1 air box 6, and the two through holes 63 are opened, which plays the role of switching the connection between the through hole 63 and the No. 3 air box 81, making it easier to control the separate cooling and shaping of the outer and inner sides of the rubber track. When the square sliding mold 17 and the two arc-shaped sliding molds 18 are closed, the two arc-shaped sliding molds 18 are located on both sides of the square sliding mold 17, pressing the curved surfaces of the two side extension plates 94, pressing the two side extension plates 94 into the interior of the square sliding mold 17. The third elastic element contracts and is subjected to force, allowing the square sliding mold 17 to slide and close with the two arc-shaped sliding molds 18, ensuring the compression effect on the semi-finished rubber track during the mold closing process. When installing the steel wire cord on the annular mold 16, multiple steel wire cords are inserted from above the annular mold 16, with the first steel wire cord fitted onto the first limiting block. Between 95 and the second limiting block 96, the second steel wire cord is sleeved between the two second limiting blocks 96, which can play the role of limiting the placement of the steel wire cord. When multiple square sliding molds 17 and arc-shaped sliding molds 18 are closed, they can squeeze the first limiting block 95 and the second limiting block 96 into the ring mold 16. The fourth elastic element contracts and is subjected to force. After the mold is closed, the limited steel wire cord and the semi-finished rubber can be vulcanized and molded as a whole, reducing the problem of steel wire cord displacement and deviation during vulcanization, and ensuring the structural strength and finished product qualification rate of the rubber track after vulcanization.
