Description

Technical Field

[0001] This invention relates to the field of shoe sole forming equipment technology, and in particular to a rapid loading and unloading shoe sole forming equipment based on colored beads. Background Technology

[0002] Colored bead molding technology (usually using pre-colored micro-particles made of materials such as EVA, TPU, and rubber) has been widely used in the field of shoe sole manufacturing. By combining colored beads of different colors in a specific ratio and injecting them into a mold, the sole is then heated and pressed to form the sole.

[0003] In the prior art, such as Chinese Patent No. CN220946348U, a color mixing machine for producing EVA shoe soles is disclosed. It includes a work frame, an infusion mechanism and a liftable shoe module installed on the work frame. A forming seat is set below the shoe module on the work frame. The forming seat has a shoe cavity that penetrates the upper and lower ends of the forming seat. A cover plate is slidably arranged on the lower end surface of the forming seat. A first control mechanism for changing the front and back position of the cover plate is provided on the work frame. This structure allows the cover plate to slide after the shoe sole is formed, and then the shoe module to move downward to push the shoe sole out of the shoe cavity. This makes the process of picking up the shoe sole automatic and does not require manual labor. Therefore, it can avoid the situation where workers are burned during the process of picking up the material.

[0004] In the above technical solution, the sole is ejected from the shoe cavity by moving the shoe module downwards. However, during injection molding, the sole may stick to the shoe module due to the heat of the injection molding process. As a result, the demolding effect is affected when the sole is ejected because of the adhesion between the sole and the shoe module. At the same time, the position of the molding seat may be misaligned with that of the shoe module during the movement. Misalignment will cause gaps at the mold joint, and the molten colored beads will overflow and form flash, which requires additional repair and increases production costs.

[0005] Based on this, a rapid loading and unloading shoe sole forming device based on colored beads is proposed. Summary of the Invention

[0018] Preferably, a piston is rotatably connected to the bottom end of the rotating rod, the surface of the piston is slidably connected to the inner wall of the sealing cylinder, and the lower surface of the sealing cylinder is fixedly connected to the upper surface of the base plate.

[0019] Preferably, the positioning spray assembly includes multiple positioning rods fixedly connected to the lower surface of the upper mold, multiple positioning cylinders fixedly connected to the surfaces of the multiple lower molds, and tapered grooves formed on the inner walls of the multiple positioning cylinders.

[0020] Preferably, the opposite surfaces of the two positioning cylinders are fixedly connected to the same infusion tube, and the surface of the infusion tube is fixedly connected to a spray tube.

[0021] The significant advantages of this invention compared to existing technologies are:

[0022] Firstly, in this invention, during the mold closing process of the upper and lower molds, the positioning rod is inserted into the positioning cylinder. Under the action of the conical groove inside the positioning cylinder, if there is an error when the turntable rotates, the turntable can be finely adjusted by the adaptation of the conical groove and the positioning rod, thereby realizing the alignment of the upper mold with the lower mold for mold closing, thus improving the injection molding effect. Precise injection molding can avoid the material being squeezed out during injection due to mold closing errors, thus affecting the demolding and material discharge effect. During the process of the positioning rod being inserted into the conical groove, the positioning rod can squeeze out the mold release agent injected inside the conical groove. Under the action of the liquid delivery pipe and the liquid spraying pipe, the mold release agent is sprayed to the bottom of the upper mold, thereby preventing the upper mold from sticking when the upper mold and the lower mold are separated after injection molding, further improving the demolding and material discharge effect.

[0023] Secondly, in this invention, when the upper mold rises, the rotating rod is relatively fixed to one-way bearing 1 and one-way bearing 2, thereby enabling the rotating rod to drive one-way bearing 1 and one-way bearing 2 to move synchronously. Under the action of the ball bearings and guide groove, the rotating rod can rotate 90 degrees, thereby enabling the rib rod and limiting cylinder to drive the turntable to rotate 90 degrees. This allows the lower mold after injection molding to be rotated to the demolding position. During the rotation, multiple spherical rods 2 set below the lower mold will contact the arc-shaped convex plate in sequence and be squeezed by the arc-shaped convex plate, so that template 1, template 2 and template 3 are squeezed alternately. This allows the shoe sole formed on template 1, template 2 and template 3 to be lifted alternately, thereby allowing the bottom of the shoe sole to be torn apart from the upper surface of template 1, template 2 and template 3, thus making demolding easier.

[0024] Thirdly: When the upper mold descends again for injection molding, the rotating rod descends and drives the piston to descend, which can send the gas inside the sealing cylinder into the air inlet through the air outlet telescopic pipe and then into the air cavity through the connecting pipe, and finally blow it out to cool the ejected shoe sole and improve the demolding effect.

[0025] Fourthly, in this invention, while the rotating rod drives the piston to descend, the rotating rod also drives the rotating ring, connecting rod, and vertical plate to descend synchronously. The descent of the vertical plate can drive the descent of multiple spherical rods to achieve reciprocating compression of the rotating rods. When the rotating rods are compressed, the other end will push the top block to rise. The rise of the top block can lift the spherical rod in the middle below the lower mold, thereby enabling the separation of the shoe sole from the templates one and three during air cooling, increasing the contact area between the cold air and the shoe sole, improving the cooling effect, and facilitating demolding.

Detailed Implementation

[0038] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] This invention provides an improved, rapid loading and unloading shoe sole forming device based on colored beads. The technical solution of this invention is as follows:

[0040] like Figure 1-9 As shown, a rapid loading and unloading shoe sole forming device based on colored beads includes a base plate 1. A rotating frame 4 and a support plate 2 are fixedly connected to the upper surface of the base plate 1. A turntable 5 is rotatably connected to the upper surface of the rotating frame 4. A positioning spray assembly is provided on the turntable 5. The device also includes:

[0041] The demolding assembly includes a rotating unit, a demolding unit, and a cooling unit;

[0042] The rotating unit includes a cylinder 11, with a guide groove 14 on the inner wall of the cylinder 11. The guide angle of the guide groove 14 is 90 degrees, which can enable the rotating rod 12 to drive the turntable 5 to rotate 90 degrees. This allows the turntable 5 to reciprocate and achieve the demolding position when it drives the lower mold 6 after injection to rotate. The rotating rod 12 is slidably connected to the upper surface of the cylinder 11. A one-way bearing 15 is fixedly connected to the surface of the rotating rod 12. A ball bearing 31 is fixedly connected to the surface of the one-way bearing 15. An upper mold 7 is provided on the support plate 2. The top end of the rotating rod 12 is rotatably set on one side of the upper mold 7. Through the cooperation of the ball bearing 31 and the guide groove 14, the rotating rod drives the one-way bearing 13 to rotate 90 degrees.

[0043] The demolding unit includes multiple lower molds 6. The inner walls of the multiple lower molds 6 are slidably connected with template 1 40, template 2 41 and template 3 42. The lower surfaces of template 1 40, template 2 41 and template 3 42 are all fixedly connected with ball rod 2 48. The lower surface of the rotating frame 4 is fixedly provided with arc-shaped protrusion plate 24.

[0044] The cooling unit includes a sealing cylinder 25, with an air inlet pipe 19 and an air outlet telescopic pipe 20 fixedly connected to the surface of the sealing cylinder 25, and an arc-shaped head 22 fixedly connected to the top end of the air outlet telescopic pipe 20.

[0045] like Figure 2 and Figure 3 As shown, a fixed frame 10 is fixedly connected to the upper surface of the base plate 1, and a cylinder 11 is fixedly connected to the inner wall of the fixed frame 10. The ball bearing 31 is adapted to slide and connected to the inner wall of the guide groove 14. A rotating hole is opened through the upper surface of the turntable 5. The inner wall of the rotating hole is rotatably connected to the surface of the cylinder 11. A one-way bearing 13 is fixedly connected to the surface of the rotating rod 12.

[0046] Two ribs 17 are fixedly connected to the surface of the one-way bearing 13, and two limiting cylinders 16 are fixedly connected to the upper surface of the turntable 5. The inner walls of the two limiting cylinders 16 are slidably connected to the surfaces of the corresponding two ribs 17. Through the cooperation of the ribs 17 and the limiting cylinders 16, the rotation of the ribs 17 and the limiting cylinders 16 can be achieved without affecting the rotation rod 12 driving the ribs 17 to descend.

[0047] A hydraulic rod 3 is fixedly installed on the upper surface of the support plate 2. The output end of the hydraulic rod 3 is fixedly connected to the upper surface of the upper mold 7. A connecting plate 9 is fixedly connected to one side of the upper mold 7. The inner wall of the connecting plate 9 is rotatably connected to the top end of the rotating rod 12.

[0048] like Figure 4 and Figure 5As shown, a top block 36 is slidably disposed on one side of the arc-shaped convex plate 24, and a rotating ball rod 38 is rotatably disposed on one side of the arc-shaped convex plate 24. Through the arrangement of the arc-shaped convex plate 24, template 1 40, template 2 41, and template 3 42 can be alternately lifted under the action of the ball rod 38, thereby improving the demolding effect. Template 1 40, template 2 41, and template 3 42 are tightly connected to each other to prevent the molten colored beads from forming flash. Springs 49 are sleeved on the surface of multiple ball rods 48. Two fixing rods are fixedly connected to the lower surface of the rotating frame 4. 23. One end of each of the two fixed rods 23 is fixedly connected to one side of the arc-shaped convex plate 24. A sliding groove 33 is provided on one side of the arc-shaped convex plate 24. Limiting grooves 35 are provided on both sides of the inner wall of the sliding groove 33. The inner wall of the sliding groove 33 and the two limiting grooves 35 are slidably connected to the same top block 36. A spring 34 is fixedly connected to the inner bottom wall of the sliding groove 33. The top end of the spring 34 is fixedly connected to the lower surface of the top block 36. Two bearing rods 37 are fixedly connected to one side of the arc-shaped convex plate 24. A rotating ball rod 38 is rotatably connected to the opposite face of the two bearing rods 37.

[0049] A rotating ring 26 is rotatably connected to the surface of the rotating rod 12. A connecting rod 27 is fixedly connected to the surface of the rotating ring 26. A vertical plate 28 is fixedly connected to one end of the connecting rod 27. Multiple sliding holes are opened on one side of the vertical plate 28. A spherical rod 29 is slidably connected to the inner wall of each of the multiple sliding holes. A spring 30 is sleeved on the surface of each of the multiple spherical rods 29. (The elastic coefficient of the spring 30 sleeved on the spherical rod 29 is greater than the elastic coefficient of the spring 34 set on the bottom wall of the slide groove 33.) Therefore, when descending, the spherical rod 29 will first squeeze the rotating ball rod 38 to descend. When the rotating ball rod 38 rotates to its maximum limit, the spring 30 is compressed, and the spherical rod 29 slides and disengages from the rotating ball rod 38, thereby realizing reciprocating compression and further improving the cooling effect.

[0050] like Figure 2 and Figure 4 As shown, each of the multiple lower molds 6 has a connecting pipe 43 fixedly connected to one side, and each of the multiple connecting pipes 43 has an air inlet head 44 fixedly connected to its surface. The arc-shaped head 22 can form a cooperative connection with the air inlet head 44. The extension and retraction of the air outlet telescopic pipe 20 can realize the raising and lowering of the arc-shaped head 22, thereby facilitating the connection with the arc-shaped head 22. One-way valves 21 are fixedly installed on the surfaces of the air inlet pipe 19 and the air outlet pipe. A spring 32 is provided inside the air outlet telescopic pipe 20. The spring 32 is sleeved on the surface of the telescopic pipe of the air outlet telescopic pipe 20. An arc-shaped groove 50 is opened on the inner wall of the air inlet head 44. The inner wall of the arc-shaped groove 50 is adapted to slide and connect with the surface of the arc-shaped head 22. Each of the multiple lower molds 6 has an air cavity 51 inside, and both ends of the multiple connecting pipes 43 extend into the air cavity 51.

[0051] A piston 18 is rotatably connected to the bottom end of the rotating rod 12. The surface of the piston 18 is slidably connected to the inner wall of the sealing cylinder 25, and the lower surface of the sealing cylinder 25 is fixedly connected to the upper surface of the base plate 1.

[0052] like Figure 7 and Figure 8 As shown, the positioning spray assembly includes multiple positioning rods 8 fixedly connected to the lower surface of the upper mold 7, multiple positioning cylinders 39 fixedly connected to the surfaces of multiple lower molds 6, and tapered grooves 45 formed on the inner walls of the multiple positioning cylinders 39. The tapered grooves 45 can correct the position of the upper mold 7 and the lower mold 6. The surfaces of the multiple positioning rods 8 are respectively adapted to slide and connected to the inner walls of the corresponding multiple tapered grooves 45. Multiple adaptation grooves are formed on the upper surface of the turntable 5, and the multiple lower molds 6 and the multiple positioning cylinders 39 are respectively fixedly connected to the inner walls of the corresponding multiple adaptation grooves.

[0053] The two positioning cylinders 39 are fixedly connected to the same infusion pipe 46 on their opposite sides. The surface of the infusion pipe 46 is fixedly connected to a spray pipe 47. The surface of the spray pipe 47 is provided with multiple spray nozzles, which can increase the spraying range of the release agent and thus improve the release effect.

[0054] The specific working method is as follows: When in use, firstly, colored beads are injected into the lower mold 6, and at the same time, release agent is injected into multiple positioning cylinders 39. Then, the hydraulic rod 3 is activated by the controller to drive the upper mold 7 to descend. The descent of the upper mold 7 can realize mold closing and injection molding. During the mold closing process of the upper mold 7 and the lower mold 6, the positioning rod 8 will be inserted into the positioning cylinder 39. Under the action of the conical groove 45 inside the positioning cylinder 39, if there is an error when the turntable 5 rotates, the turntable 5 can be finely adjusted by the matching of the conical groove 45 and the positioning rod 8, so as to realize that the upper mold 7 is aligned with the lower mold 6 for mold closing, thereby improving the injection molding effect. Precise injection molding can avoid the raw material being squeezed out during injection due to mold closing error, thus affecting the demolding and material feeding effect.

[0055] During the process of the positioning rod 8 being inserted into the conical groove 45, the positioning rod 8 can squeeze out the release agent injected into the conical groove 45. Under the action of the liquid delivery pipe 46 and the liquid spraying pipe 47, the release agent is sprayed to the bottom of the upper mold 7, so as to avoid the upper mold 7 sticking when the upper mold 7 and the lower mold 6 are separated after injection molding, and further improve the demolding and material discharge effect.

[0056] When the upper mold 7 descends, it drives the rotating rod 12 to descend synchronously. The rotating rod 12 rotates relative to the one-way bearing 13 and the one-way bearing 15. Therefore, the rotating rod 12 will not drive the rib 17 to rotate during descent, and thus will not drive the rotation of the limiting cylinder 16 and the turntable 5. When the upper mold 7 rises, the rotating rod 12 is relatively fixed relative to the one-way bearing 13 and the one-way bearing 15, so that the rotating rod 12 can drive the one-way bearing 13 and the one-way bearing 15 to move synchronously. Under the action of the ball 31 and the guide groove 14, the rotating rod 12 can rotate 90 degrees, so that the rib 17 and the limiting cylinder 16 drive the turntable 5 to rotate 90 degrees, which can rotate the lower mold 6 after injection molding. Upon reaching the demolding station, during the rotation process, multiple spherical rods 48 positioned below the lower mold 6 will sequentially contact the arc-shaped convex plate 24 and be squeezed by the arc-shaped convex plate 24, thereby alternately squeezing the templates 40, 41, and 42. This allows the shoe soles formed on the templates 40, 41, and 42 to be alternately lifted, thus tearing the bottom of the shoe soles from the upper surfaces of the templates 40, 41, and 42, making demolding easier. After the turntable 5 rotates 90 degrees, the multiple spherical rods 48 are all at the highest point of the arc-shaped convex plate 24, pushing the shoe soles on the templates 40, 41, and 42 out of the lower mold 6.

[0057] When the upper mold 7 descends again for injection molding, the rotating rod 12 descends, driving the piston 18 to descend. This allows the gas inside the sealing cylinder 25 to be sent through the air outlet telescopic pipe 20 into the air inlet head 44 and then through the connecting pipe 43 into the air chamber 51, and finally blown out to cool the ejected shoe sole and improve the demolding effect. When the rotating plate rotates, the arc-shaped groove 50 below the air inlet head 44 will squeeze the arc-shaped head 22 set at the top of the air outlet telescopic pipe 20. The arc-shaped head 22 is subjected to the action of the second spring 32. When squeezed, the arc-shaped head 22 descends until it corresponds to the air inlet head 44. Under the action of the second spring 32, the arc-shaped head 22 and the air inlet head 44 are connected, thus completing the air intake work.

[0058] While the rotating rod 12 drives the piston 18 to descend, the rotating rod 12 also drives the rotating ring 26, connecting rod 27 and vertical plate 28 to descend synchronously. The descent of the vertical plate 28 can drive the descent of multiple spherical rods 29, realizing reciprocating compression of the rotating ball rod 38. When the rotating ball rod 38 is compressed, the other end will push the top block 36 to rise. The rise of the top block 36 can lift the spherical rod 48 in the middle below the lower mold 6, so that the sole can be separated from the template 40 and template 42 during air cooling, increasing the contact area between the cold air and the sole, improving the cooling effect and facilitating demolding. (The elastic coefficient of the spring 30 sleeved on the spherical rod 29 is greater than the elastic coefficient of the spring 34 set on the bottom wall of the slide groove 33). Therefore, when descending, the spherical rod 29 will first compress the rotating ball rod 38 to descend. When the rotating ball rod 38 rotates to its maximum limit, the spring 30 is compressed, and the spherical rod 29 slides and disengages from the rotating ball rod 38, thus realizing reciprocating compression and further improving the cooling effect.

[0059] After cooling, the shoe sole is cut into pieces. After cutting, the upper mold 7 rises again during the injection molding process, thus achieving continuous reciprocating operation and improving work efficiency.
