[0002] In today's sole manufacturing field, the sole molding process has a series of problems that need to be solved. At present, most soles on the market are made of EVA. This material shows many advantages in the molding process, but it also comes with a significant disadvantage. When the sole completes the molding process in the mold, due to its special material properties, it will be strongly adsorbed on the inner wall of the mold. In the current industry, many times, we have to rely on manual demoulding, but the efficiency is extremely low.

[0024] In one embodiment, please refer to the attached manual. Figure 1 , 3 As shown in Figures 5, 6, 8 and 10, the molding mechanism 4 includes a lower template 42 arranged on the rotating plate 32, an upper template 41 is arranged above the lower template 42, the upper template 41 and the lower template 42 are connected by a hinge 46, and the upper template 41 can rotate relative to the lower template 42 through the hinge 46; an extrusion die 43 is arranged on the upper template 41, a molding groove 44 is arranged on the lower template 42, an injection port 47 is arranged on the lower template 42, and an exhaust hole 45 is arranged on the upper template 41, and EVA material is injected between the extrusion die 43 and the molding groove 44 through the injection port 47 to mold the sole 101.

[0025] By cooperating the upper template 41 and the lower template 42, and the extrusion die 43 and the molding groove 44, the sole 101 injected into the molding groove 44 is easy to take out; the injection port 47 is conveniently connected with the injection molding mechanism 2, so that the injection molding mechanism 2 can inject the EVA material into the molding groove 44, and the injection port 47 is located at the tail of the molding groove 44, and the exhaust hole 45 is located at the front end of the upper template 41. When the EVA material is injected into the molding groove 44, the gas is discharged upward from the exhaust hole 45.

[0026] In one embodiment, please refer to the attached manual. Figure 6-7As shown in Figures 11 and 11, the blocking mechanism 6 includes a first cavity 61 and a second cavity 62 opened on the extrusion die 43, the first cavity 61 and the second cavity 62 are connected; the top of the second cavity 62 is connected to the exhaust hole 45; at least one air channel 63 is opened on the inner wall of the second cavity 62, and the air channel 63 discharges the gas inside the molding groove 44 to the outside during injection molding; a plurality of slide grooves 64 are arranged on the extrusion die 43, and slide rods 65 are arranged inside the slide grooves 64 in a one-to-one correspondence, and a blocking ball 66 is connected to the slide rod 65, and the slide rod 65 slides inside the slide groove 64, and the blocking ball 66 slides inside the second cavity 62; a magnetic block 67 is arranged at the connection between the second cavity 62 and the exhaust hole 45, and an opening for gas to pass through is arranged on the magnetic block 67; when the blocking ball 66 is adsorbed by the magnetic block 67, the exhaust hole 45 is blocked; after the blocking ball 66 is separated from the magnetic block 67, the exhaust hole 45 is exhausted.

[0027] In order to complete the injection molding in the closed space between the extrusion die 43 and the molding groove 44, and to facilitate the removal of the sole 101 from the inside of the molding groove 44 after injection molding; the gas is discharged to the outside of the molding mechanism 4 through the exhaust hole 45 during injection molding; when the EVA material is injected into the molding groove 44, the air continuously enters the second cavity 62 from the first cavity 61, and then the air is discharged from the inside of the exhaust hole 45 through the opened airway 63; preferably, the magnetic block can be an electromagnet, and the magnetism of the magnetic block is controlled by a circuit; when the gas When the air is completely discharged, the surface of the EVA material inside the molding groove 44 will first contact the sealing ball 66, which is a metal structure that can be adsorbed by the magnetic block 67, and the sealing ball 66 is a hollow sphere; when the sealing ball 66 is pushed to move upward along the second cavity 62, it will be adsorbed by the magnetic block 67; thereby blocking the exhaust hole 45, so that the injected EVA material cannot continue to spread upward, thereby just filling the space between the extrusion die 43 and the molding groove 44. At this time, the injection molding mechanism 2 no longer injects EVA material. At this time, a column 102 structure is formed inside the first cavity 61 and the second cavity 62, and the column 102 is convenient for subsequent clamping by a robot. The robot pulls the column 102, and the column 102 drives the entire sole 101 to be taken out from the inside of the molding groove 44; when the upper mold is opened, the blocking ball 66 adsorbed on the top of the column 102 enters the bottom of the first cavity 61 under the pulling force of the column 102 and the action of gravity, and the blocking ball 66 is limited by the sliding rod 65 so that the blocking ball 66 will not enter the inside of the second cavity 62; if a small amount of EVA material is adsorbed on the blocking ball 66 when the blocking ball 66 is separated from the column 102, it can be directly removed by flipping the blocking ball 66. The first wall and the second cavity 62 on the extrusion die 43 only need to be cleaned; during injection molding, the mechanism can discharge the gas, which is convenient for the EVA material to be injected into the interior of the molding groove 44. When the injection molding is completed, the injected EVA material needs to be sealed, and the sealing ball 66 seals the EVA material between the extrusion die 43 and the molding groove 44; and when disassembling, the sealing ball 66 is reset to facilitate the sealing ball 66 to allow the gas to be smoothly discharged from the interior of the molding mechanism 4 during the next injection molding; the injection molded sole 101 will not contain bubbles, and the EVA material will not overflow from the interior of the molding mechanism 4 during injection molding; the yield rate and production efficiency of the molding of the sole 101 are improved.

[0029] The guide member includes a first guide rod 51 and a second guide rod 52, and the first guide rod 51 and the second guide rod 52 are connected end to end; the first guide rod 51 is an arc rod, and the circumferential surface of the first guide rod 51 is parallel to the surface of the closed upper template 41; the second guide rod 52 is a spiral upward arc rod structure; when the guide block 53 slides on the first guide rod 51, the upper template 41 does not flip; when the guide block 53 slides onto the second guide rod 52, the upper template 41 starts to flip until the flip angle is greater than 90°.

[0030] The first guide rod 51 is provided so that when the locking mechanism 7 contacts, the locking mechanism 7 unlocks the upper template 41 and the lower template 42, and at this time, the upper template 41 has not rotated yet; so that the upper template 41 can smoothly enter the second guide rod 52 along the first guide rod 51, and when the upper template 41 slides along the second guide rod 52 through the guide block 53, the locking mechanism 7 is still in the unlocked state; refer to the attached manual Figure 1 As shown, the first station is the position where the molding mechanism 4 is located on the first guide rod 51; the station sequence is clockwise; when the guide block 53 slides to the third station, the guide block 53 has not yet separated from the end of the second guide rod 52, at this time, the robot takes out the sole 101 from the inside of the molding groove 44; when the upper template 41 rotates from the third station to the fourth station, the reset block 56 abuts against the outer wall of the upper template 41, and the surface of the reset block 56 is an arc structure. The reset block 56 pushes the upper template 41 to rotate until the angle between it and the lower template 42 is less than 90°; the upper template 41 will flip onto the lower template 42 under the action of gravity, and at this time, the locking mechanism 7 just locks the upper template 41 and the lower template 42.

[0031] In one embodiment, please refer to the attached manual. Figure 6 , 8As shown in , 9 and 12, the locking mechanism 7 includes a locking assembly and an unlocking assembly; the locking assembly is used to lock the upper template 41 and the lower template 42; the unlocking assembly unlocks the locking assembly; The locking mechanism 7 includes a first locking block 74 arranged on the upper template 41; a second locking block 75 is arranged inside the lower template 42, and the first locking block 74 and the second locking block 75 are engaged with each other; an inner chamber 78 is arranged inside the lower template 42, and a locking rod 73 is arranged inside the inner chamber 78, and the second locking block 75 is arranged on the locking rod 73, and a movable rod 76 is arranged on the locking rod 73, and a second elastic member 77 is sleeved on the movable rod 76, and the second elastic member 77 is used to push the locking rod 73 to reset; an extrusion block 79 is arranged on the locking rod 73, and the extrusion block 79 abuts against the unlocking component.

[0033] When the first guide rod 51 enters the interior of the guide groove 54, the end of the first guide rod 51 will be squeezed on the contact head 710. Since the end surface of the contact head 710 is an arc-shaped structure, the first guide rod 51 will force the contact head 710 to move downward, and the contact head 710 drives the unlocking rod 71 to move. The end of the unlocking rod 71 pushes the extrusion block 79 to move, and the extrusion block 79 drives the locking rod 73 to move laterally. The first locking block 74 on the locking rod 73 moves laterally synchronously. At this time, the first locking block 74 will be misaligned with the second locking block 75, so that the first locking block 74 no longer engages with the second locking block 75; when the guide block 53 enters the second guide rod 52 from the first guide rod 51, the upper template 41 begins to flip, and when the upper template 41 rotates, the first locking block 74 is dislocated from the second locking block 75 The misaligned position of the two locking blocks 75 is far away from the second locking block 75; when the upper template 41 is pushed downward by the reset block 56, the unlocking rod 71 is not squeezed at this time, and the unlocking rod 71 cannot push the locking rod 73 to move; when the upper template 41 rotates downward, the first locking block 74 squeezes the second locking block 75 to compress the second elastic member 77, and the movable rod 76 moves; when the first locking block 74 slides over the second locking block 75 and is located below the second locking block 75, the second elastic member 77 pushes the movable rod 76 to reset; at this time, the second locking block 75 limits the first locking block 74, thereby achieving a locking effect; after the first locking block 74 and the second locking block 75 are locked, the upper template 41 and the lower template 42 are closed, which is convenient for injecting EVA material into the interior of the molding mechanism 4.

[0034] In one embodiment, please refer to the attached manual. Figure 1-4 As shown, the injection molding mechanism 2 includes an injection molding machine 21 arranged above the frame 31, a connecting pipe 24 is arranged at the bottom of the injection molding machine 21, a sleeve 23 is arranged on the connecting pipe 24, a telescopic member 22 is arranged on the injection molding machine 21, the telescopic end of the telescopic member 22 is connected to the sleeve 23, a plug 25 is connected to the sleeve 23, and the plug 25 corresponds to the injection port 47 one by one.

[0035] The EVA material is injected into the injection port 47 through the set injection molding machine 21 (which is the prior art and will not be described here in detail). The telescopic part 22 can be an electric telescopic rod or a telescopic cylinder. The telescopic part 22 drives the insertion tube 25 to cooperate with the injection port 47 to realize the injection of EVA material into the molding mechanism 4.

[0036] When the present invention is in use, the motor 34 is turned on, the motor 34 rotates to drive the gear 33 to rotate, the gear 33 pushes the convex tooth 35 to rotate, so that the rotating plate 32 rotates, and the rotating plate 32 rotates to drive the forming mechanism 4 to rotate. When one of the upper templates 41 rotates to the first station, the first guide rod 51 enters the interior of the guide groove 54, and the end of the first guide rod 51 is squeezed on the contact head 710. Since the end surface of the contact head 710 is an arc-shaped structure, the first guide rod 51 will force the contact head 710 to move downward, and the contact head 710 drives the unlocking rod 71 to move, and the end of the unlocking rod 71 pushes the extrusion block 79 to move. When the locking cam 75 is in the closed position, the locking cam 75 is in the closed position, and the locking cam 75 is in the closed position. When the locking cam 75 is in the closed position, the locking cam 75 is in the closed position, and the locking cam 75 is in the closed position. When the locking cam 75 is in the closed position, the locking cam 75 is in the closed position, and the locking cam 75 is in the closed position. When sliding to the third station, the guide block 53 has not yet separated from the end of the second guide rod 52. At this time, the robot takes out the sole 101 from the inside of the molding groove 44. When the upper template 41 rotates from the third station to the fourth station, the reset block 56 abuts against the outer wall of the upper template 41. The surface of the reset block 56 is an arc-shaped structure. The reset block 56 pushes the upper template 41 to rotate until the angle between the upper template 41 and the lower template 42 is less than 90°. The upper template 41 will flip onto the lower template 42 under the action of gravity. At this time, the upper template 41 is pushed by the reset block 56 and rotates downward. At this time, the unlocking rod 71 is not squeezed. , the unlocking rod 71 cannot push the locking rod 73 to move; when the upper template 41 rotates downward, the first locking block 74 squeezes the second locking block 75 to compress the second elastic member 77, and the movable rod 76 moves; when the first locking block 74 slides over the second locking block 75 and is located below the second locking block 75, the second elastic member 77 pushes the movable rod 76 to reset; at this time, the second locking block 75 limits the first locking block 74, thereby achieving the locking effect; after the first locking block 74 and the second locking block 75 are locked, the upper template 41 and the lower template 42 are closed, which is convenient for injecting EVA material into the interior of the molding mechanism 4.When the molding mechanism 4 moves to the workstation corresponding to the injection molding mechanism 2, the injection molding machine 21 injects the EVA material into the injection port 47. When the EVA material is injected into the molding groove 44, air continuously enters the second cavity 62 from the first cavity 61, and then the air is discharged from the exhaust hole 45 through the opened airway 63; when the gas is exhausted, the surface of the EVA material inside the molding groove 44 will first contact the blocking ball 66, which is a metal structure that can be adsorbed by the magnetic block 67, and the blocking ball 66 is a hollow sphere; when the blocking ball 66 is pushed to move upward along the second cavity 62, it will be adsorbed by the magnetic block 67; thereby blocking the exhaust hole 45, so that the injected EVA material cannot continue to spread upward, so as to just fill the space between the extrusion die 43 and the molding groove 44. At this time, the injection molding mechanism 2 no longer injects EVA material. At this time, the first cavity 61 and the second cavity 62 form a column 102 structure, and the column 102 is convenient for subsequent clamping by the robot. The robot pulls the column 102, and the column 102 drives the entire sole 101 to be taken out from the inside of the molding groove 44; when the upper mold is opened, the blocking ball 66 adsorbed on the top of the column 102 enters the bottom of the first cavity 61 under the pulling force of the column 102 and the action of gravity, and the sliding rod 65 limits the blocking ball 66 so that the blocking ball 66 will not enter the second cavity. 62; when the injection molding is completed, the injected EVA material needs to be sealed, and the sealing ball 66 seals the EVA material between the extrusion die 43 and the molding groove 44; and when disassembling, the sealing ball 66 is reset to facilitate the sealing ball 66 to allow the gas to be smoothly discharged from the inside of the molding mechanism 4 during the next injection molding; the injection molded sole 101 will not contain bubbles, and the EVA material will not overflow from the inside of the molding mechanism 4 during injection molding; the yield rate and production efficiency of the molding of the sole 101 are improved.
