Description

Technical Field

[0001] This utility model relates to the field of rubber track technology, specifically to a one-time vulcanization molding die for seamless rubber tracks. Background Technology

[0002] Rubber tracks are tracks made of rubber and skeleton materials, and are widely used in engineering machinery, agricultural machinery, military equipment and robots. Compared with steel tracks, rubber tracks are significantly lighter, weighing 56% less than steel tracks. This allows tracked vehicles to travel faster and accelerate better, while also reducing fuel consumption and increasing range. Based on the elasticity and deformation capacity of rubber, rubber tracks, when working in conjunction with components such as drive wheels, idler wheels and road wheels, are equivalent to a "soft landing," resulting in significantly reduced noise.

[0003] In the production and manufacturing of seamless rubber tracks, vulcanization molding dies are key equipment.

[0004] Existing seamless rubber track vulcanization molding molds often require manual assistance during the demolding process. The rubber track is removed from the mold by prying or pulling. However, precise control of force is difficult during manual demolding, easily causing scratches and deformation on the rubber track surface, leading to a decrease in product yield and waste of raw materials. Therefore, a seamless rubber track one-step vulcanization molding mold is proposed. Utility Model Content

Detailed Implementation

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.

[0029] Please see Figure 1-6 The present invention provides a technical solution: including a base plate 1, and a forming mechanism 2 and a vibration mechanism 3 are arranged above the base plate 1;

[0030] Molding mechanism 2 includes a vulcanizing section and a demolding section;

[0031] The vulcanizing section includes a vulcanizing mold 21, and the demolding section includes two demolding sleeves 27 and an ejector ring 29;

[0032] The bottom surface of the vulcanizing mold 21 is fixedly connected to the top surface of the base plate 1. The top surface of the vulcanizing mold 21 is slidably connected to the bottom surfaces of the two demolding sleeves 27. Two sets of fixing plates 23 are fixedly installed on the outer walls of the two demolding sleeves 27, and the outer walls of the two sets of fixing plates 23 are bolted to the outer wall of the vulcanizing mold 21. The top surface of the ejector ring 29 passes through the bottom surface of the base plate 1 and the bottom surface of the vulcanizing mold 21, extending to the inner side of the vulcanizing mold 21. A lifting plate 28 is fixedly installed on the bottom surface of the ejector ring 29. A threaded rod 212 is rotatably installed on the bottom surface of the base plate 1 through a bearing seat. The threaded rod 212 passes through the top surface of the lifting plate 28 and extends to the bottom of the lifting plate 28. A control motor 211 is fixedly installed on the bottom surface of the base plate 1. Two pulleys 210 are fixedly sleeved on the outer wall of the output end of the control motor 211 and the outer wall of the threaded rod 212, respectively. The two pulleys 210 are connected by a belt drive. Next, two limiting blocks 213 are fixedly installed on the bottom surface of the base plate 1. The bottom surfaces of the two limiting blocks 213 extend through the top surface of the lifting plate 28 to the bottom of the lifting plate 28. Two limiting rails 25 are fixedly installed on the bottom surface of the base plate 1. Two sets of limiting sleeves 24 are slidably sleeved on the outer walls of the two limiting rails 25. Two sets of limiting frames 26 are fixedly installed on the outer walls of the two sets of limiting sleeves 24. The inner sides of the two sets of limiting frames 26 are fixedly connected to the outer walls of the two demolding sleeves 27. An electric telescopic rod 32 is fixedly installed on the top surface of the fixed frame 31. The bottom surface of the electric telescopic rod 32 extends through the top surface of the fixed frame 31 to the inner side of the fixed frame 31. The bottom surface of the output end of the electric telescopic rod 32 is fixedly connected to the top surface of the lower pressure plate 36. A limiting rod 37 is fixedly installed on the top surface of the lower pressure plate 36. The top surface of the limiting rod 37 slides through the inner side of the fixed frame 31 to the top of the fixed frame 31.

[0033] The vibration mechanism 3 includes a fixed frame 31, with the top surface of the bottom plate 1 fixedly connected to the inner side of the fixed frame 31. A lower pressure plate 36 is provided inside the fixed frame 31, and a drive motor 310 is fixedly provided on the top surface of the lower pressure plate 36. The production bottom surface of the drive motor 310 extends through the top surface of the lower pressure plate 36 to the inner side of the lower pressure plate 36. Two striking blocks 33 are fixedly provided on the outer wall of the output end of the drive motor 310. Two striking plates 35 are slidably provided on the inner side of the vulcanizing mold 21. A connecting rail 34 is fixedly provided on the inner side of the vulcanizing mold 21. The outer wall of the connecting rail 34 is slidably connected to the inner side of the two striking plates 35. Two springs 38 are provided between the two striking plates 35. The outer walls of the two springs 38 are fixedly connected to the side of the two striking plates 35 respectively. Two limiting plates 39 are fixedly provided on the inner side of the vulcanizing mold 21. The outer walls of the two limiting plates 39 are in contact with the side of the two striking plates 35 respectively.

[0034] In use, the rubber raw material is placed into the vulcanizing mold 21. The vulcanizing mold 21 heats and pressurizes the rubber raw material for vulcanization. During the vulcanization process, the electric telescopic rod 32 extends downward, pushing the lower pressure plate 36 downward. At the same time, the limiting rod 37 slides within the fixed frame 31, serving as a guide and limiting element to ensure the smooth downward movement of the lower pressure plate 36. After the lower pressure plate 36 moves to a certain position, the drive motor 310 starts. The output end of the drive motor 310 drives the striking block 33 to rotate. The striking block 33 continuously strikes the striking plate 35 inside the vulcanizing mold 21. Since the striking plate 35 slides on the connecting rail 34 and a spring 38 is provided between the two striking plates 35, the striking plate 35 vibrates within the vulcanizing mold 21 under the impact force of the striking block 33. The vibration is transmitted to the rubber raw material, causing the rubber raw material to fill the mold cavity more evenly during the vulcanization process, eliminating internal air bubbles, and improving the vulcanization quality of the rubber track.

[0035] After vulcanization, the demolding stage begins. First, the two sets of fixing bolts 22 are unscrewed, which allows the two demolding sleeves 27 to move, thus separating the two demolding sleeves 27 from the rubber track. At this time, the control motor 211 is turned on, driving the threaded rod 212 to rotate in the opposite direction. Under the restriction of the limit block 213, the lifting plate 28 moves upward along the threaded rod 212, thereby pulling the ejection ring 29 upward, thus ejecting the vulcanized rubber track from the vulcanization mold 21, and finally achieving the smooth demolding of the jointless rubber track.
