Description

Technical Field

[0001] The invention relates to the technical field of recycled rubber, in particular to a recycled rubber molding device. Background Art

[0002] Recycled rubber refers to waste vulcanized rubber and scraps of vulcanized products. After physical and chemical processes such as crushing, heating, and mechanical treatment, it is transformed from an elastic state into a rubber material with plasticity and viscosity that can be re-vulcanized. The equipment used for molding recycled rubber is a rubber injection molding machine, which injects the rubber directly from the barrel into the mold cavity to achieve high-temperature rapid vulcanization. It has the advantages of high production efficiency and stable product quality.

[0003] In the prior art, during the production process of recycled rubber, the molding method used is mostly injection molding.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. When in use, the entire demoulding assembly is lowered to separate the molding groove and the molding block. The heat is dissipated for the first time at this time. The bidirectional synchronous motor is started to drive the threaded rod to drive the threaded ring and the movable plate to move. When the two movable plates drive the two adjustment blocks to move inward at the same time, the adjustment rods sliding inside the two adjustment holes on the same adjustment block will move closer during the movement, so the distance between the movable template and the bottom plate is shortened. The demoulding top block pushes upward to separate the rubber product from the movable template. Then the heat between the rubber product and the movable template will be dissipated.

[0018] 2. When in use, the height of the demoulding assembly can be adjusted by adjusting the height of the height-adjusting assembly. By starting the hydraulic cylinder, the hydraulic cylinder is extended. During the extension process, the first movable rod and the second movable rod support and connect the two scissor-type connecting rods. At the same time, the first slider slides inside the first slide, and the second slider slides inside the second slide. The scissor-type connecting rod is composed of multiple connecting rods. When the hydraulic cylinder extends and drives the mounting plate to rise, the angle in the middle between the scissor-type connecting rods will become smaller. Conversely, when descending, the angle at the same position will increase.

[0019] 3. When in use, the fixed plate and the support rod play a role of fixed support. During injection, the static template and the dynamic template fit closely, and the rubber material that has been processed into small particles is poured from the feed hopper into the feed tube. At this time, the heating coil is turned on to heat and melt the rubber particles inside the feed tube into a flowing state. The servo motor is started to adjust the descending speed of the molten rubber material by controlling the rotation speed of the spiral blade. When the descending speed is too fast, the rubber material can be transported upward by reversing, which can avoid the situation where the rubber material inside the injection cylinder is filled with too much. By starting the electric telescopic rod and shortening it, the push rod is driven to press the piston downward, and the rubber material inside the injection cylinder is pressed into the corresponding molding groove through each feed hole.

[0032] Example 1: Reference Figure 1 - Fig. 9 As shown, the present invention provides a technical solution: a recycled rubber molding device, comprising a height adjustment component 1, a demoulding component 2 is fixedly installed on the top of the height adjustment component 1, and the demoulding component 2 includes a support plate 201, and the top of the support plate 201 is fixedly connected to a triangular plate frame 202 near the edges on both sides, and the opposite sides of the two triangular plate frames 202 are fixedly connected to a sleeve frame 208, and the inner walls of the two sleeve frames 208 are slidably connected to a pull-out plate 209, and the opposite sides of the two pull-out plates 209 are fixedly connected to a movable The two movable plates 210 are fixedly connected to the opposite sides of the two movable plates 210 with adjustment blocks 211, and the front surfaces of the two adjustment blocks 211 are symmetrically provided with two adjustment holes 215, and the inner wall of each adjustment hole 215 is slidably connected to an adjustment rod 216, and both ends of each adjustment rod 216 are fixedly connected to fixed rods 217, wherein a movable plate 213 is fixedly connected between one side of the four fixed rods 217 above, and a plurality of forming blocks 214 are fixedly connected to the top of the movable plate 213, and each forming block 214 has a A top material hole 218 is opened at the bottom, and a bottom plate 212 is fixedly connected between one side of the four fixing rods 217 below. A plurality of demoulding top blocks 220 are fixedly connected to the top of the bottom plate 212, and each demoulding top block 220 corresponds to the position of each top material hole 218. A reinforcing plate 203 is fixedly connected to the middle of the top of the support plate 201. A bidirectional synchronous motor 204 is arranged on the outer surface of the reinforcing plate 203. The two output shafts of the bidirectional synchronous motor 204 are fixedly connected to the threaded rod 206. An anti-slip block 207 is welded to one end of each threaded rod 206, a threaded ring 205 is fixedly connected to the bottom of the two movable plates 210, the outer surfaces of the two threaded rods 206 are threadedly connected to the inner walls of the two threaded rings 205, the bottom of the movable template 213 is fixedly connected to a limiting sleeve 219 near each ejection hole 218, the top of the bottom plate 212 is fixedly connected to a limiting tube 221 near each demoulding ejection block 220, and each limiting sleeve 219 is slidably sleeved on the outside of each limiting tube 221.

[0033] In this embodiment, when in use, after the melted regenerated rubber is injection molded, the hydraulic cylinder 102 is first started to lower the mounting plate 103, thereby driving the entire demoulding assembly 2 to lower, and then separating the molding groove 316 and the molding block 214. The heat is dissipated for the first time at this time, and then, by starting the bidirectional synchronous motor 204, its two output shafts are rotated, thereby driving the two threaded rods 206 to rotate, and the two threaded rings 205 and the movable plate 210 connected thereto are driven to move during the rotation. At this time, the two pull-out plates 209 slide inside the two sleeve frames 208 respectively, and do not affect the movement of the movable plate 210 while playing a supporting role.

Therefore, the demoulding top block 220 will slide inside the ejection hole 218 to push up the molded rubber product. Multiple demoulding top blocks 220 are pushed up at the same time, so that the rubber product can be separated from the movable template 213. Then, the heat between the rubber product and the movable template 213 will be dissipated. At this time, when the rubber product is removed, there will be no sudden hot air to scald the hands of the staff, which improves safety. In addition, the limiting tube 221 slides inside the limiting sleeve 219, which can ensure that the movable template 213 and the bottom plate 212 are always kept parallel, which improves stability. After demoulding is completed, the bidirectional synchronous motor 204 is started again to change the position between the adjusting rod 216 and the adjusting hole 215, so that the top of the demoulding top block 220 is flush with the bottom surface of the molding block 214, and the recycled rubber can continue to be injection molded.

During injection, the static template 302 and the dynamic template 213 are tightly fitted, and the rubber material that has been processed into small particles is poured from the feed hopper 310 into the feed pipe 311. At this time, the heating coil 312 is turned on, so that the rubber particles in the feed pipe 311 are heated and melted into a flowing state. By starting the servo motor 313, the output shaft of the servo motor 313 rotates, thereby driving the spiral blade 315 to rotate, and the spiral blade 31 5 is tightly fitted with the inner wall of the feed pipe 311, the servo motor 313 is forward and reverse, and the speed of the molten rubber material falling can be adjusted by controlling the rotation speed of the spiral blade 315.

By starting the electric telescopic rod 305 to shorten it, the push rod 308 is driven to press the piston 309 downward, and then the rubber material inside the injection cylinder 301 is pressed into the corresponding molding groove 316 through each feeding hole 303, and a molding cavity is formed between the molding groove 316 and the corresponding molding block 214, and the molten rubber material completes the molding operation in the molding cavity.

[0038] The method of use and working principle of the device: when in use, the demoulding component 2 is installed on the top of the height-adjusting component 1, so that the height of the demoulding component 2 can be adjusted by adjusting the height of the height-adjusting component 1, and the hydraulic cylinder 102 is started to extend. During the extension process, the first movable rod 110 will be pushed upward, and the first movable rod 110 can move while rotating, and the second movable rod 104 cannot move and can only rotate. The first movable rod 110 and the second movable rod 104 support and connect the two scissor-type connecting rods 109. At the same time, the first slider 108 will slide inside the first slide 105, and the second slider 107 will slide inside the second slide 106. The scissor-type connecting rod 109 is composed of a plurality of connecting rods. When the hydraulic cylinder 102 extends and drives the mounting plate 103 to rise, the angle between the middle parts of the scissor-type connecting rods 109 will become smaller. On the contrary, when it descends, the angle at the same position will increase. When in use, the fixing plate 401 and the support rod 402 play a role of fixed support, and the connecting plate 403 and the connecting rod 404 can not only play a role of increasing the stability of the two support rods 402, but also be used to install the electric telescopic rod 305 and the servo motor 313. During injection, the static mold plate 302 and the dynamic mold plate 213 are tightly fitted, and the rubber material that has been processed into small particles is poured from the feed hopper 310 into the feed pipe 311. At this time, the heating coil 312 is turned on, so that the rubber particles in the feed pipe 311 are heated and melted into a flowing state, and then the rubber particles in the feed pipe 311 are heated and melted into a flowing state. By starting the servo motor 313, the output shaft of the servo motor 313 rotates, thereby driving the spiral blade 315 to rotate. The outer surface of the spiral blade 315 is closely fitted with the inner wall of the feed pipe 311. The servo motor 313 is forward and reverse. By controlling the rotation speed of the spiral blade 315, the descending speed of the molten rubber material can be adjusted. When the descending speed is too fast, the rubber material can be transported upward by reversing, which can avoid the situation where the rubber material inside the injection cylinder 301 is filled with too much. By starting the electric telescopic rod 305 and shortening it, the push rod 308 is driven to press the piston 309 downward, and then the rubber material inside the injection cylinder 301 is pressed into the corresponding molding groove 316 through each feeding hole 303. A molding cavity is formed between the corresponding molding block 214, and the molten rubber material completes the molding operation in the molding cavity. When in use, after the molten recycled rubber is injection molded, the hydraulic cylinder 102 is first started to lower the mounting plate 103, thereby driving the entire demoulding assembly 2 to lower, and then the molding groove 316 and the molding block 214 are separated. The heat is dissipated for the first time at this time, and then, by starting the bidirectional synchronous motor 204, the two output shafts are rotated, thereby driving the two threaded rods 206 to rotate, and the two threaded rings 205 and the movable plate 210 connected thereto are driven to move during the rotation. At this time, the two pull-out plates 209 slide inside the two sleeve frames 208 respectively, playing a supporting role while not affecting the movement of the movable plate 210.The two adjustment holes 215 on the same adjustment block 211 are in an eight-shaped shape. When the two movable plates 210 drive the two adjustment blocks 211 to move inward at the same time, the adjustment rods 216 sliding inside the two adjustment holes 215 on the same adjustment block 211 will move closer during the movement, so the distance between the movable plate 213 and the bottom plate 212 will become closer and closer, so the demoulding top block 220 will slide inside the ejection hole 218 to push the molded rubber product upward. Multiple demoulding top blocks 220 are pushed upward at the same time, so that the rubber The rubber product is separated from the movable template 213, and the heat between the rubber product and the movable template 213 will be dissipated. In addition, the limit tube 221 slides inside the limit sleeve 219, which can ensure that the movable template 213 and the bottom plate 212 are always parallel. After demoulding is completed, the bidirectional synchronous motor 204 is started again to change the position between the adjustment rod 216 and the adjustment hole 215, so that the top of the demoulding top block 220 is flush with the bottom surface of the molding block 214, and the recycled rubber can continue to be injected.
