[0034] The preparation method of the low-density, high-elasticity, wear-resistant sports shoe sole comprises the following steps:
[0035] Step 1: Add EVA to a double-roll mill to melt, add PBSs after the EVA is completely melted, add modified nano zinc oxide and a cross-linking agent after mixing and heating, and prepare an EVA / PBSs copolymer, and mix the EVA / PBSs copolymer, polyester-type thermoplastic polyurethane elastomer, waste rubber powder and modified diatomaceous earth in a double-roll mill, and then add a ligand-type titanate coupling agent and a vulcanizing agent to obtain a mixture;

[0037] Step 3: Put the sole materials of different colors into the injection molding machine, melt the materials in the injection molding machine, inject them into the sole mold under pressure, and then cool them to form;
[0038] Step 4: Cut, trim and polish the cooled and formed sole to make the edge of the sole flat and smooth. At the same time, trim the edge, pattern and other details of the sole to meet the design requirements of the sole. Finally, the sole after cooling and trimming needs to be quality inspected.
[0039] When the raw material needs to be injection molded, the mold is installed inside the installation port 3, the raw material is placed in the injection molding structure 8, and the driving rod 4 is used to drive the mold to move upward to the bottom of the conveying pipe 9. The raw material is conveyed from the conveying pipe 9 to the inside of the mold through the feeding structure 7. When the raw material is conveyed, the mold is moved to its original position by the driving rod 4, and the first motor 10 is started by the controller to drive the rotating rod 11 and the rotating block 12 to rotate, so that the collecting trough at the bottom of the rotating block 12 rotates to the bottom of the conveying pipe 9, and the raw material remaining at the bottom of the conveying pipe 9 is collected to prevent the raw material from dripping and being difficult to clean. The rotating block 12 rotates and drives the first scraper 19 to move to the top of the raw material inside the mold, and then the first electric push rod 18 is started to drive the first scraper 19 to move downward to fit the top surface of the raw material. The second motor 13 is started to drive the rotating shaft 14 to rotate, so that the first movable block 15 drives the first mounting block 17 to move along the slide groove, so that the first electric push rod 18 at the bottom of the first mounting block 17 drives the first scraper 19 to move back and forth, thereby making the first scraper 19 scrapes the raw materials evenly to facilitate injection molding of the raw materials. When the first movable block 15 moves, it drives the connecting block 16 to move along the inner wall of the fixed groove. The connecting block 16 drives the first fixed block 20 at the top to move along the two movable grooves, so that the second scraper 21 moves along the top of the rotating block 12 to scrape the raw materials remaining at the bottom of the conveying pipe 9. The scraped raw materials fall into the collecting tank for collection, so as to facilitate the accumulation of residual raw materials to block the conveying pipe 9, which is inconvenient for the conveying of raw materials. When the raw materials at the bottom of the conveying pipe 9 are scraped clean and no longer drip, and the raw materials inside the mold are scraped evenly, the first electric push rod 18 is started to drive the first scraper 19 to move to the top of the mold. The rotation of the first motor 10 drives the rotating rod 11 and the rotating block 12 to rotate, so that the first scraper 19 moves to the original position, exposing the conveying pipe 9, and then the driving structure is started to rotate the rotating table 2, so that the next mold moves to the bottom of the conveying pipe 9 to continue to convey the raw materials for injection molding. After injection molding, the sole inside the mold is taken out for cooling molding and testing.
[0040] like Figure 2-8As shown, the conveying pipe 9 is arranged corresponding to the installation port 3, the first motor 10, the rotating rod 11 and the rotating block 12 are all located on one side of the conveying pipe 9, the two movable grooves are located on both sides of the collecting groove, the collecting groove is located at the bottom of the fixed groove, the first fixed block 20 extends through the fixed groove to the top of the rotating block 12, the second scraper 21 is located on the side of the collecting groove away from the rotating rod 11, the bottom of the second scraper 21 is slidably connected with the top of the rotating block 12, scraping structures are arranged on both sides of the rotating block 12, and a limiting structure 22 is arranged on the side of the rotating block 12 close to the conveying pipe 9.
[0041] Since the conveying pipe 9 is arranged corresponding to the installation port 3, the mold installed in the installation port 3 can correspond to the conveying pipe 9, so that the conveying pipe 9 can convey the raw materials to the mold, which is convenient for injection molding. Since the first motor 10, the rotating rod 11 and the rotating block 12 are all located on one side of the conveying pipe 9, and the two movable grooves are located on both sides of the collecting groove, the rotating block 12 will not block the discharge of the raw materials when the conveying pipe 9 is conveying. When the rotating block 12 rotates, it is convenient to move the first electric push rod 18 and the first scraper 19 to the bottom of the conveying pipe 9 and the top of the mold. The second motor 13, the rotating shaft 14 and the first movable block 15 are installed through the fixed groove, and the second motor 13 drives the rotating shaft 14 rotates, and the rotating shaft 14 is limited by moving the connecting block 16 and the inner wall of the fixed groove, so that when the first movable block 15 moves, the first scraper 19 and the second scraper 21 can move at the same time, and the scraping of the raw material and the scraping of the raw material at the bottom of the conveying pipe 9 are carried out at the same time, so as to improve the effect of injection molding. At the same time, the scraping structure can scrape the raw material dripping on the rotating table 2, which is convenient for long-term residue and difficult to clean. After the raw material is scraped evenly, the limiting structure 22 is moved to the bottom of the installation port 3 by the rotation of the rotating block 12, and is located on both sides of the mold, so that when the driving rod 4 pushes the mold to move, the mold is limited to improve stability.
[0042] like Figure 6-8 As shown, the bottom end of the first movable block 15 is slidably connected to the slide groove, the first mounting block 17 is located at the bottom of the slide groove, the first mounting block 17 is slidably connected to the bottom of the rotating block 12, the first electric push rod 18 and the first scraper 19 are located at the bottom of the rotating block 12 away from the end of the conveying pipe 9, and the first scraper 19 is in a U-shape.
[0043] When the first movable block 15 moves, it drives the movement of the first mounting block 17 and the first electric push rod 18, thereby driving the first scraper 19 to move toward the end of the rotating block 12 close to the first motor 10. Since the first scraper 19 is in a U-shape, it is convenient for the scraper to scrape the raw materials evenly and at the same time, the raw materials on the inner wall of the mold are scraped into the raw materials inside the mold, so that the raw materials can be fully utilized and easy to use.
[0044] like Figure 6-7As shown, the scraping structure includes a second mounting block 23, one side of the second mounting block 23 is fixedly connected to the rotating block 12, a sliding groove is opened on one side of the second mounting block 23, a moving block 24 is slidably connected inside the sliding groove, one end of the moving block 24 passes through the rotating block 12 and is fixedly connected to one end of the connecting block 16, one side of the moving block 24 is fixedly connected to a second electric push rod 25, and the bottom of the second electric push rod 25 is fixedly connected to a scraping block 26, the second mounting block 23, the moving block 24, the second electric push rod 25 and the scraping block 26 are symmetrically arranged around the center of the rotating block 12, the moving block 24 is located on the side of the second mounting block 23 close to the second scraper 21, and the scraping blocks 26 are located on both sides of the second scraper 21.
[0045] When the rotating block 12 drives the scraper to rotate to the top of the mold, the rotating block 12 drives the scraping blocks 26 on both sides of the mounting block to rotate to the top of the rotating table 2, and the second electric push rod 25 is started to push the scraping block 26 to move to the top surface of the rotating table 2 to fit it. When the second motor 13 drives the rotating shaft 14 to rotate so that the first movable block 15 drives the connecting block 16 to move, the connecting block 16 drives the moving block 24 to move in the sliding groove inside the mounting block. After the conveying tube 9 has completed the conveying, when the rotating block 12 has not yet rotated to the bottom of the conveying tube 9, the raw material falls onto the rotating table 2, so that the scraping block 26 moves to scrape off the residual raw material to prevent the raw material from adhering for a long time and being difficult to clean.
[0046] like Figure 9-10 As shown, the limiting structure 22 includes a third motor 221, the output end of the third motor 221 is fixedly connected to a threaded rod 222, one end of the threaded rod 222 is rotatably connected to a second fixed block 223, one side of the second fixed block 223 is fixedly connected to a connecting rod 224, one end of the connecting rod 224 is fixedly connected to one side of a rotating plate 226, the outer surface of the threaded rod 222 is threadedly connected to a movable plate 225, both ends of the movable plate 225 are hinged to the rotating plate 226, one end of the rotating plate 226 is hinged to a second movable block 227, one side of the second movable block 227 is hinged to the second fixed block 223 The inner wall is slidably connected, one side of the second movable block 227 is fixedly connected with a fixed rod 228, one side of the fixed rod 228 is fixedly connected with an electric telescopic plate 229, one side of the third motor 221 is fixedly installed with the inner wall of the fixed groove, the third motor 221 is located at the top of the second motor 13, one end of the threaded rod 222 passes through one side of the rotating plate 226, the movable plate 225 is located inside the fixed groove, both ends of the movable plate 225 are slidably connected with a limiting rod, one end of the limiting rod passes through one side of the rotating plate 226 and is fixedly connected to the second fixed block 223, and one end of the limiting rod is located between the two connecting rods 224.
[0047] When the mold is installed inside the installation opening 3 and the electric telescopic plates 229 are located on both sides of the mold, the threaded rod 222 is driven to rotate by starting the third motor 221, and the movable plate 225 is moved along the direction of the threaded rod 222 by utilizing the limiting rod. When the movable plate 225 moves toward the third motor 221, the rotating plate 226 is deflected at an angle, thereby pushing the second movable block 227 to move toward the inside of the second fixed block 223. Through the action of the fixed rod 228, the electric telescopic plates 229 are moved closer to each other, thereby moving the electric telescopic plates 229 to both sides of the mold. The mold is limited by the extension of the electric telescopic plates 229. Therefore, when the mold moves upward, the mold can be prevented from being offset, thereby causing the raw material to fall to the outside of the mold or onto the rotating table 2, thereby facilitating accurate material cutting.
[0048] like Figure 9-10 As shown, two movable openings are opened on the rotating plate 226 near the side of the second fixed block 223, one end of the rotating plate 226 passes through the two movable openings and extends to the side of the rotating plate 226, the second movable block 227 is located on the side of the rotating plate 226, and it is arranged opposite to the two movable openings, the fixing rod 228 and the electric telescopic plate 229 are arranged symmetrically with the center of the second fixed block 223, the electric telescopic plate 229 is located at the top of the mounting opening 3, and it is arranged corresponding to the mounting opening 3, one side of the telescopic end of the electric telescopic plate 229 is fixedly connected to two connecting springs 27, and one end of the two connecting springs 27 is fixedly connected to the fixed plate 28.
[0049] Through the two movable openings, when the rotating plate 226 rotates, its end away from the movable plate 225 can be deflected to push the second movable block 227 to move, so that the two electric telescopic plates 229 move relative to each other. When the electric telescopic plate 229 is extended, it drives the fixed plate 28 to move to one side of the mold, and at the same time, the fixed plate 28 limits the two sides of the mold. Through the action of the two connecting springs 27, when the mold moves to the bottom of the conveying pipe 9, the mold can be further fixed, thereby improving the stability of the mold for unloading.
[0050] Working principle: when in use, first install the mold on the installation port 3, control the third motor 221 to rotate through the control box 6, so that the driving rod 4 pushes the mold to move to the bottom of the conveying tube 9, and utilizes the limiting rod to make the movable plate 225 move along the direction of the threaded rod 222. When the movable plate 225 moves toward the third motor 221, the rotating plate 226 deflects an angle, so that one end of the rotating plate 226 passes through the movable port and pushes the second movable block 227 to move toward the inside of the second fixed block 223. Through the action of the fixed rod 228, the electric telescopic plate 229 is extended to drive the fixed plate 28 to move closer to each other. Through the action of the two connecting springs 27, the fixed plate 28 is moved to both sides of the mold to limit the mold, and then through injection molding. The structure 8 and the material discharge structure transport the raw materials to the inside of the conveying pipe 9, and then the conveying pipe 9 transports the raw materials to the inside of the mold. After the raw materials are transported, the mold is driven to move to its original position by the driving rod 4. Under the action of the third motor 221, the threaded rod 222, the movable plate 225, the rotating plate 226 and the second movable block 227, the electric telescopic plate 229 returns to its original position, and then the fixed plate 28 is driven to shrink by the electric telescopic plate 229, so that the fixed plate 28 and the electric telescopic plate 229 no longer limit the two sides of the mold and move to the rear side of the mold. Then, the first motor 10 is started to drive the rotating rod 11 and the rotating block 12 to rotate, so that the first scraper 19 rotates to the bottom of the mold, and the collecting trough rotates to the bottom of the conveying pipe 9 to collect the raw materials dripping from the bottom of the conveying pipe 9.
[0051] When the first scraper 19 moves to the top of the mold, the scraping block 26 moves to the top of the rotating table 2, and the first electric push rod 18 is started to drive the first scraper 19 to move downward to fit the top surface of the raw material. By starting the second motor 13 to drive the rotating shaft 14 to rotate, the first movable block 15 drives the first mounting block 17 to move along the slide groove, so that the first electric push rod 18 at the bottom of the first mounting block 17 drives the first scraper 19 to move back and forth, so that the first scraper 19 scrapes the raw material evenly. When the first movable block 15 moves, it drives the connecting block 16 to move along the inner wall of the fixed groove. The connecting block 16 drives the top first fixed block 20 to move along the two moving grooves, so that the second scraper 21 moves along the top of the rotating block 12 to scrape the raw material remaining at the bottom of the conveying pipe 9. The scraped raw material falls into the collecting tank for collection. At the same time, when the rotating block 12 drives the scraper to rotate to the top of the mold, the rotating block 12 drives the scraping blocks 26 on both sides of the mounting block to rotate to the top of the rotating table 2, and starts The second electric push rod 25 pushes the scraping block 26 to move to the top surface of the rotating table 2 to fit therewith. When the second motor 13 drives the rotating shaft 14 to rotate so that the first movable block 15 drives the connecting block 16 to move, the connecting block 16 drives the moving block 24 to move in the sliding groove inside the mounting block, so that the scraping block 26 moves to scrape off the residual raw materials on the rotating table 2. When the raw materials at the bottom of the conveying pipe 9 are scraped clean and no longer drip, and the raw materials inside the mold are scraped evenly, the first electric push rod 18 is started to drive the first scraper 19 to move to the top of the mold, and the second electric push rod 25 drives the scraping block 26 to move to its original position. The rotation of the first motor 10 drives the rotating rod 11 and the rotating block 12 to rotate, so that the first scraper 19 moves to its original position, exposing the conveying pipe 9, and then the driving structure is started to rotate the rotating table 2, so that the next mold moves to the bottom of the conveying pipe 9 to continue conveying raw materials for injection molding. After injection molding, the sole inside the mold is taken out for cooling molding, and then inspection is performed.
[0052] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
