Description

Technical Field

[0001] The present invention relates to the technical field of shoe-making equipment, and particularly to a vertical vacuum sole molding machine. Background Art

[0002] When the sole is molded, glue needs to be applied between the wear-resistant material of the outsole and the midsole that provides elastic function, and hot pressing is performed in a mold to achieve the adhesion and molding of the sole. During the pressing process, there are bubbles between the midsole and the outsole, and the bubbles increase due to heating. If the bubbles are not discharged, the adhesion strength of the molded sole will be reduced, thus affecting the overall production quality.

[0003] On the other hand, when the sole molding machine is in use, the mold needs to be heated, so the molded sole will carry a certain amount of heat. When the staff takes out the sole, if the protective measures are not in place, it is easy to get scalded, and the automation is insufficient. Summary of the Invention

[0022] The present invention will be further described below with reference to the accompanying drawings: Such as Figure 1 —— Figure 6As shown in the figure, this embodiment provides a vertical vacuum sole molding machine, which includes a wallboard frame 1, an upper vacuum system 2, an upper heating system 3, a lower vacuum system 4, a lower cooling system 5, a first rotating tray system 6, an upper support roller device 7, a second rotating tray system 8 and a lower support roller device 9. The wallboard frame 1 successively has a top plate 11, a middle bottom plate 12 and a lower bottom plate 13 from top to bottom. The upper vacuum system 2 is detachably installed between the top plate 11 and the middle bottom plate 12 to achieve vacuum pumping during mold heating. The upper heating system 3 is detachably installed between the top plate 11 and the middle bottom plate 12 to achieve mold heating. The lower vacuum system 4 is detachably installed between the middle bottom plate 12 and the lower bottom plate 13 to achieve vacuum pumping during mold shaping. The lower cooling system 5 is detachably installed between the middle bottom plate 12 and the lower bottom plate 13 to achieve mold cooling.

[0023] The upper support roller device 7 is installed on the upper vacuum system 2 to facilitate rising during the horizontal movement of the mold to support the mold. The upper support roller device 7 moves up and down above the middle bottom plate 12 following the upper vacuum system 2. That is to say, during the process of the mold entering the upper vacuum system 2, the upper support roller device 7 rises following the upper vacuum system 2. The mold slides onto the upper support roller device 7 under the traction of the first rotating tray system 6. Subsequently, the upper support roller device 7 descends following the upper vacuum system 2 and places the mold on the upper heating system 3 for heating preparation. The lower support roller device 9 is installed on the lower vacuum system 4 to facilitate rising during the horizontal movement of the mold to support the mold. The lower support roller device 9 moves up and down above the lower bottom plate 13 following the lower vacuum system 4. That is to say, during the process of the mold entering the lower vacuum system 4, the lower support roller device 9 rises following the lower vacuum system 4. The mold slides onto the lower support roller device 9 under the traction of the second rotating tray system 8. Subsequently, the lower support roller device 9 descends following the lower vacuum system 4 and places the mold on the lower cooling system 5 for cooling preparation. The first rotating tray system 6 is liftably installed on one side of the wallboard frame 1. The first rotating tray system 6 reciprocates between the upper support roller device 7 and the lower support roller device 9 to traction the mold in and out. The second rotating tray system 8 is liftably installed on the other side of the wallboard frame 1. The second rotating tray system 8 reciprocates between the upper support roller device 7 and the lower support roller device 9 to traction the mold in and out. The upper vacuum system 2 and the lower vacuum system 4 improve the bonding strength of each layer of the sole.

[0024] Specifically, the upper vacuum system 2 includes an upper vacuum cover 21 and an upper sealing plate 22. The upper vacuum cover 21 is installed on the wall panel frame 1 so as to be liftable by an upper sealing power cylinder 23. The upper sealing power cylinder 23 is installed on the wall panel frame 1. The upper sealing power cylinder 23 is transmission-connected to the upper vacuum cover 21. The upper sealing plate 22 is installed on the upper side of the middle bottom plate 12. An upper vacuum chamber is formed between the upper vacuum cover 21 and the upper sealing plate 22, thereby generating a vacuum environment. The upper supporting roller device 7 is installed on the upper vacuum cover 21 and rises and falls with the upper vacuum cover 21, thereby lifting the mold when pushing the mold horizontally, thereby providing guidance for the mold.

[0025] Specifically, the upper heating system 3 includes an upper large cylinder assembly 31, an upper heating plate 33 and a lower heating plate 32. The upper large cylinder assembly 31 passes upward through the upper vacuum system 2 and is then installed on the top plate 11. The upper heating plate 33 is installed on the upper large cylinder assembly 31, and the lower heating plate 32 is installed on the middle bottom plate 12. The sizes of the upper heating plate 33 and the lower heating plate 32 are both smaller than the upper vacuum system 2. The upper heating plate 33 and the lower heating plate 32 pressurize and heat the mold under the drive of the upper large cylinder assembly 31, and the upper vacuum cover 21 and the upper sealing plate 22 form a sealed space. The upper heating plate 33 and the lower heating plate 32 are located in the sealed space, thereby realizing heating under vacuum conditions, completely expelling bubbles, and ensuring bonding strength.

[0026] Specifically, the lower vacuum system 4 includes a lower vacuum hood 41 and a lower sealing plate 42. The lower vacuum hood 41 is installed on the wall panel frame 1 so as to be liftable through a lower sealing power cylinder 43. The lower sealing power cylinder 43 is installed on the wall panel frame 1. The lower sealing power cylinder 43 is transmission-connected to the lower vacuum hood 41. The lower sealing plate 42 is installed on the upper side of the lower plate bottom plate 13. A lower vacuum chamber is formed between the lower vacuum hood 41 and the lower sealing plate 42, thereby generating a vacuum environment. The lower supporting roller device 9 is installed on the lower vacuum hood 41 and rises and falls with the lower vacuum hood 41, thereby lifting the mold when pushing the mold horizontally, thereby providing guidance for the mold.

[0027] Specifically, the lower cooling system 5 includes a lower large oil cylinder assembly 52, an upper cooling plate 53 and a lower cooling plate 51. The lower large oil cylinder assembly 52 passes upward through the lower vacuum system 4 and is then installed on the middle bottom plate 12. The upper cooling plate 53 is installed on the lower large oil cylinder assembly 52, and the lower cooling plate 51 is installed on the lower plate bottom plate 13. The sizes of the upper cooling plate 53 and the lower cooling plate 51 are both smaller than the lower vacuum system 4. The upper cooling plate 53 and the lower cooling plate 51 cool the mold under the drive of the lower large oil cylinder assembly 52, and the lower vacuum cover 41 and the lower sealing plate 42 form a sealed space. The upper cooling plate 53 and the lower cooling plate 51 are located in the sealed space, thereby achieving cooling and shaping under vacuum conditions.

[0028] Specifically, the first rotating tray system 6 includes a first lifting device 61, a first transverse movement guiding shaft 62, a first transverse movement linear bearing 63, a first rotating servo motor 64, and a first rotating arm 65. The first lifting device 61 is installed on the wall panel frame 1. The first transverse movement guiding shaft 62 is installed at the lifting end of the first lifting device 61. The first lifting device 61 uses a conventional motor-driven chain and sprocket transmission mechanism to realize the lifting of the first transverse movement guiding shaft 62. A number of rollers for carrying the transverse sliding of the mold are provided at the lifting end of the first lifting device 61. The first rotating servo motor 64 is slidably installed on the first transverse movement linear bearing 63. The first transverse movement linear bearing 63 is slidably installed on the first transverse movement guiding shaft 62. The first rotating arm 65 is installed at the output end of the first rotating servo motor 64. The first rotating servo motor 64 drives the first rotating arm 65 to rotate. The first rotating arm 65 is inserted into the preset hole position of the mold. After the first rotating servo motor 64 drives the first rotating arm 65 to rotate, the first transverse movement linear bearing 63 slides along the first transverse movement guiding shaft 62, thereby realizing the pushing of the mold, and further realizing the horizontal movement of the mold. The first lifting device 61 drives the first rotating servo motor 64 to reciprocate between the upper support roller device 7 and the lower support roller device 9, thereby realizing the lifting of the mold. Please note that the sliding fit between the first transverse movement linear bearing 63 and the first transverse movement guiding shaft 62 converts the rotational movement of the first rotating arm 65 into the translational movement of the mold.

[0029] Specifically, the principle of the translational movement of the mold lies in that a cylindrical pin is provided on the first rotating arm 65. After the pin is inserted into the preset hole position of the mold, when the first rotating servo motor 64 drives the first rotating arm 65 to rotate, the cylindrical pin on the first rotating arm 65 rotates relative to the preset hole position of the mold. The mold slides horizontally under the constraint of each roller, while the first rotating servo motor 64 follows the first transverse movement linear bearing 63 and slides on the first transverse movement guiding shaft 62, thereby realizing the translational movement of the mold.

[0030] Specifically, the upper support roller device 7 includes an upper support frame 71, a number of upper support guiding bearings 72, and a number of upper support bearing members 73. Each upper support guiding bearing 72 and each upper support bearing member 73 are installed on the upper support frame 71, and the rotational axes of each upper support guiding bearing 72 and each upper support bearing member 73 are perpendicular to each other. The upper support frame 71 is installed on the upper vacuum system 2, and thus follows the movement of the upper vacuum system 2 to realize lifting, and further realizes placing the mold on the lower heating plate 32.

[0031] Specifically, the upper support frame 71 is installed on the upper vacuum cover 21. When the upper vacuum cover 21 rises, the upper support frame 71 follows and rises, driving each upper support guide bearing 72 and each upper support bearing 73 to rise, thereby lifting the mold from the lower heating plate 32, facilitating the first rotating arm 65 to pull out the mold. When the upper vacuum cover 21 descends, the upper support frame 71 descends, thereby placing the mold on the lower heating plate 32.

[0032] Specifically, similar to the first rotating tray system 6, the second rotating tray system 8 includes a second lifting device, a second transverse alignment shaft, a second transverse linear bearing, a second rotating servo motor, and a second rotating arm. The second lifting device is installed on the wall panel frame 1, and the second transverse alignment shaft is installed at the lifting end of the second lifting device. The second lifting device uses a conventional motor-driven chain and sprocket transmission mechanism to achieve the lifting of the second transverse alignment shaft. A number of rollers for carrying the lateral sliding of the mold are provided at the lifting end of the second lifting device. The second rotating servo motor is slidably installed on the second transverse linear bearing, and the second transverse linear bearing is slidably installed on the second transverse alignment shaft. The second rotating arm is installed at the output end of the second rotating servo motor. The second rotating servo motor drives the second rotating arm to rotate. The second rotating arm is inserted into a preset hole position of the mold. After the second rotating servo motor drives the second rotating arm to rotate, the second transverse linear bearing slides along the second transverse alignment shaft, thereby realizing the pushing of the mold and further realizing the horizontal movement of the mold. The second lifting device drives the second rotating servo motor to reciprocate between the upper support roller device 7 and the lower support roller device 9, thereby realizing the lifting of the mold. Note that the sliding fit between the second transverse linear bearing and the second transverse alignment shaft converts the rotational movement of the second rotating arm into the translational movement of the mold.

[0033] Specifically, the principle of the translational movement of the mold is that the second rotating arm is provided with a cylindrical pin. After the pin is inserted into the preset hole position of the mold, when the second rotating servo motor drives the second rotating arm to rotate, the cylindrical pin on the second rotating arm rotates relative to the preset hole position of the mold, and the mold slides laterally under the constraint of each roller, while the second rotating servo motor follows the second transverse linear bearing and slides on the second transverse alignment shaft, thereby realizing the translational movement of the mold.

[0034] Specifically, the lower support roller device 9 includes a lower support frame 91, a number of lower support guide bearings 92, and a number of lower support bearings 93. Each lower support guide bearing 92 and each lower support bearing 93 are installed on the upper support frame 71, and the rotation axes of each lower support guide bearing 92 and each lower support bearing 93 are perpendicular to each other. The lower support frame 91 is installed on the upper vacuum system 2, and thus follows the movement of the lower vacuum system 4 to realize lifting, thereby realizing placing the mold on the lower cooling plate 51.

[0035] Generally speaking, after the mold equipped with the outsole and the midsole is conveyed to the lifting end of the first lifting device 61, it is pushed into the upper support roller device 7 by the first rotating arm 65. Subsequently, the upper support roller device 7 descends until the upper vacuum hood 21 descends to form a sealed space with the upper sealing plate 22, and the upper heating plate 33 and the lower heating plate 32 heat the mold and evacuate the air. After the heating is completed, the upper support roller device 7 ascends, the second rotating arm pulls the mold out of the upper support roller device 7, the second lifting device lowers the mold, the second rotating arm pushes the mold into the lower support roller device 9, and the lower support roller device 9 descends until the lower vacuum hood 41 descends to form a sealed space with the lower sealing plate 42, and the upper cooling plate 53 and the lower cooling plate 51 cool the mold and evacuate the air. The upper cooling plate 53 and the lower cooling plate 51 cool the mold by using conventional water cooling or air cooling methods, which maximally ensures the firm adhesion of the outsole and the midsole.
