Description

Technical Field

[0001] The invention discloses elastic wear-resistant sports shoe sole forming equipment, belonging to the technical field of shoe material production equipment. Background Art

[0002] Sports shoes are shoes designed and manufactured according to the characteristics of people participating in sports or traveling. The soles of sports shoes are different from ordinary leather shoes and rubber shoes. They are generally soft and elastic, which can play a certain cushioning role, enhance elasticity during exercise, and some can also prevent ankle injuries. Sports shoe soles are an important part of sports shoes. In order to improve the elasticity of sports shoe soles, high-elastic materials are usually used, but this will lead to poor wear resistance of the soles. In order to make sports shoes have both high elasticity and good wear resistance, a wear-resistant outsole is generally glued under the elastic midsole. However, gluing not only increases the labor intensity of workers, but also the connection between the midsole and the outsole is not firm after gluing, making the wear-resistant outsole easy to fall off after wearing.

A mounting column 17 is arranged at the center of the base 8. The rotating table 10 is rotatably connected to the mounting column 17. Four molding molds 6 are arranged and are distributed at 90° angles with the mounting column 17 as the center.

A first molding cavity 41 is arranged in the first convex mold 45. The intermediate mold 11 is located between the upper mold 12 and the lower mold 7, and the intermediate mold 11 includes two L-shaped shielding molds 28. The two shielding molds 28 are slidably arranged on both sides of the first convex mold 45. A first power member for driving the two shielding molds 28 to move closer to or away from each other is arranged on the lower mold 7, so as to close the first molding cavity 41 when the two shielding molds 28 collide with each other. The two shielding molds 28 are both arranged on the side close to each other. There is a groove 43, a second punch 29 is provided at the bottom of the upper mold 12, a second molding cavity 39 is provided in the second punch 29, and the second molding cavity 39 is closed when the second punch 29 and the first punch 45 are molded together, a feed hole 38 is also provided on the upper mold 12 and the second punch 29, one end of the feed hole 38 has a spherical recess 24, a second power member for driving the rotating table 10 to rotate is provided on the base 8, and a first cylinder 22 for driving the lower mold 7 to move upward is provided on the base 8, a fixing frame 5 is provided on the mounting column 17, a first discharge hopper 4 is provided at one end of the fixing frame 5, and an injection molding device is provided at the other end, the first discharge hopper 4 and the injection molding device are symmetrically distributed at 180°, the blanking port of the first discharge hopper 4 and the injection molding port of the injection molding device are located directly above the spherical recess 24 in two of the molding molds 6, a limit assembly 30 for limiting the upward movement distance of the upper mold 12 is provided on the rotating table 10, and a heating assembly is provided in the lower mold 7.

[0031] The injection molding device includes an injection molding barrel 13, a push screw, a second discharge hopper 15 and a first motor 14. The injection molding barrel 13, the first discharge hopper 4 and the second discharge hopper 15 are all installed on the fixed frame 5. The lower end of the second discharge hopper 15 is connected to the injection molding barrel 13 through a feed pipe 16. The first discharge hopper 4 and the second discharge hopper 15 are both provided with discharge valves at the discharge ports. The axis of the injection molding barrel 13 is coaxially arranged with the axis of one of the feed holes 38. The push screw is rotatably installed on the injection molding barrel 13. 3, and one end of the push screw is fixedly connected to the output shaft of the first motor 14, the first discharge hopper 4 and the second discharge hopper 15 are respectively filled with the raw material of the large sole 3 and the raw material of the midsole 1, and the discharge amount of the two is controlled by the discharge valve respectively, the raw material of the midsole 1 enters the injection molding barrel 13 through the feeding pipe 16 to be melted, and the first motor 14 drives the push screw to eject the molten raw material of the midsole 1 from the injection molding barrel 13, and enters the second molding cavity 39 through the feeding hole 38.

[0032] The limiting assembly 30 includes a first spring 33, a first limiting bolt 32 and a support column 31, one end of the support column 31 is fixedly connected to the upper mold 12, one end of the first limiting bolt 32 passes through the rotating table 10 and is fixedly connected to the support column 31, the first spring 33 is sleeved on the first limiting bolt 32, and applies a downward force to the first limiting bolt 32, and the support column 31 passes through the lower mold 7. When the first cylinder 22 drives the lower mold 7 to move upward, when the upper mold 12 and the lower mold 7 are closed, the upper mold 12 and the lower mold 7 can move upward synchronously, and the first spring 33 is compressed until the first limiting bolt 32 limits the support column 31 and the upper mold 12 to continue to move upward, so that the upper mold 12 can smoothly contact the lower end of the first discharge hopper 4 or the injection barrel 13 during the upward movement, thereby facilitating the subsequent completion of the molding of the outsole 3 or the midsole 1.

[0033] The first power component includes a second motor 27, a transmission screw 25 and a guide rod 40. Both sides of the two shielding molds 28 are provided with protrusions 44. The lower mold 7 is provided with a mounting block 26 for mounting the guide rod 40 and the transmission screw 25. The guide rod 40 and the protrusion 44 are slidably arranged. The transmission screw 25 is threadedly connected with the protrusion 44, and one end of the transmission screw 25 is fixedly connected with the output shaft of the second motor 27. The second motor 27 drives the transmission screw 25 to rotate. The transmission screw 25 has two sections of threads with opposite rotation directions. The two shielding molds 28 are threadedly connected with the two sections of threads respectively. In this way, the transmission screw 25 can be used to drive the two shielding molds 28 to move closer to or away from each other, so that the outsole 3 and the midsole 1 can be formed conveniently.

[0034] A positioning boss 46 is provided on one of the shielding molds 28, and a concave hole 42 cooperating with the positioning boss 46 is provided on the other shielding mold 28. The cooperation between the positioning boss 46 and the concave hole 42 allows the two grooves 43 to be aligned, and when the raw material of the outsole 3 is foamed, the two shielding molds 28 can be subjected to a certain pressure, thereby preventing the raw material from running out from between the two.

[0035] A booster assembly 9 is provided on the lower mold 7, and the booster assembly 9 includes a movable bolt 37, a second spring 36 and a nut 35. One end of the movable bolt 37 passes through the lower mold 7 and is connected to the nut 35. The second spring 36 is sleeved on the outer side of the movable bolt 37 and applies an upward force to the movable bolt 37. When the lower mold 7 is driven by the first cylinder 22 to upwardly resist the upper mold 12, the movable bolt 37 is compressed downward by the pressure of the upper mold 12, so that when the upper mold 12 and the lower mold 7 are opened after the midsole 1 is formed, the elastic force of the second spring 36 can apply a force to move away from each other on the upper mold 12 and the lower mold 7, thereby having a boosting effect on the mold opening.

[0036] The bottom of the lower mold 7 is provided with an ejection assembly, which includes a push rod 34, a first fixing plate 48, a second fixing plate 49, a second limiting bolt 50, a third spring 47 and a second cylinder 20. The first fixing plate 48 and the second fixing plate 49 are fixedly connected by bolts. A plurality of push rods 34 are provided, one end of which is fixed between the first fixing plate 48 and the second fixing plate 49, and the other end passes through the lower mold 7 and is flush with the bottom of the first molding cavity 41. One end of the second limiting bolt 50 passes through the first fixing plate 48 and the second fixing plate 49 and is threadedly connected to the lower mold 7. The third spring 47 is sleeved on the outer side of the second limiting bolt 50 and applies a downward force to the first fixing plate 48 and the second fixing plate 49. The first cylinder 22 and the second cylinder 20 are both installed on the base 8. The rotating table 10 is provided with a through hole 23 for the cylinder piston to pass through. After the sole is formed, the first fixing plate 48 and the second fixing plate 49 are driven upward by the second cylinder 20, so that the third spring 47 is compressed, and the push rod 34 pushes the sole upward from the first punch 45, thereby completing automatic unloading and facilitating subsequent manual material collection.

[0037] The second power member includes a third motor 19, a driving gear 18 and a driven gear 21. The driven gear 21 is fixed below the rotating table 10. The third motor 19 is fixed on the base 8. The driving gear 18 is fixed on the output shaft of the third motor 19 and meshes with the driven gear 21 for transmission. When the third motor 19 drives the driving gear 18 to rotate, the driven gear 21 can drive the rotating table 10 to rotate, thereby rotating the rotating table 10. By limiting the transmission ratio of the driving gear 18 and the driven gear 21 and the number of rotations of the driving gear 18, the rotating table 10 can be rotated 90° each time.

[0038] Working principle: When the forming mold 6 is in the initial state of the first station, the two shielding molds 28 are driven by the second motor 27 to move to the maximum distance away from each other. At this time, the upper mold 12 and the lower mold 7 are in the mold opening state. Then, the second power member drives the rotating table 10 to rotate 90°, so that the forming mold 6 rotates 90° and moves to the second station. At this time, the forming mold 6 is located below the first discharge hopper 4. Then, the first cylinder 22 drives the lower mold 7 to move upward. Since the upper mold 12 remains stationary under the action of the limit assembly 30 until the lower mold 7 and the upper mold 12 are closed, the first cylinder 2 2 continues to push the lower die 7 upward, so that the upper die 12 needs to overcome the elastic force of the first spring 33 and move upward synchronously with the lower die 7 until the spherical recess 24 contacts the lower end of the first discharge hopper 4. At this time, the discharge valve below the first discharge hopper 4 opens, and the raw material of the large bottom 3 falls into the feed hole 38 and smoothly falls into the first molding cavity 41 of the first punch 45. After the quantitative discharge of the raw material of the large bottom 3 is completed, the first cylinder 22 is reset, so that the upper die 12 and the lower die 7 are reset and keep the mold open, and then the second power member drives the molding die 6 to continue to rotate 90° and move to the third station.

[0039] Then, the first power member drives the two shielding molds 28 to approach each other until they collide with each other, and then relies on the heating component to heat the lower mold 7, and allows the raw material of the outsole 3 to be foamed and formed. The main material of the outsole 3 is rubber, which can improve the wear resistance of the outsole 3. After the outsole 3 is formed, the first power member drives the two shielding molds 28 to move away from each other, so that the outsole 3 can rely on the grooves 43 on the two shielding molds 28 during molding to form the protrusion 2 on the outsole 3, and then the second power member drives the molding mold 6 to rotate 90° again and move to the fourth station.

[0040] The lower mold 7 is driven by the first cylinder 22 to continue to move upward until the lower end of the injection barrel 13 contacts the spherical recess 24, and the first motor 14 drives the push screw to push the molten midsole 1 material in the injection barrel 13 from the second discharge hopper 15 into the feed hole 38, so that the midsole 1 material is injection molded into the second molding cavity 39. Since the midsole 1 material and the outsole 3 material are partially the same, for example, the midsole 1 material contains a small amount of rubber while ensuring high elasticity, so that the midsole 1 and the outsole 3 can be better integrated together. Since the material injection speed is very fast, the outsole 3 will not be greatly mixed with the midsole 1 due to excessive melting, and the midsole 1 material will be The convex column 2 is completely wrapped, which can ensure the elastic and wear-resistant performance of the sole, and at the same time, the two do not need to be connected by gluing, and the tear resistance of the two is effectively improved. The molded sole finally remains in the first punch 45, and the excess waste material in the feed hole 38 remains on the sole, which can be manually cut off later, and will not affect the next discharge or injection molding of the feed hole 38. Finally, the second power part drives the upper mold 12 and the lower mold 7 after the mold is opened to move back to the first station, and relies on the ejection assembly to eject the sole from the first punch 45, so as to facilitate the workers to take the material. The whole process can be basically automatically controlled without manual discharge, which can effectively improve the molding efficiency of the sole.
