DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] Embodiment 1 like Figures 1 to 4 As shown, a sole demoulding device includes a frame 1, on which a mold opening component 2, a mold turning component 3 and a material picking mechanism 5 are arranged. The mold opening component 2 is arranged on the lower side of the material picking component for unlocking and opening and closing the shoe mold, and the material picking mechanism 5 can rotate toward the shoe mold to grab the material or away from the shoe mold to release the material.

[0025] In this embodiment, the sole demoulding device is used in conjunction with a shoe mold turntable, on which a plurality of shoe molds are arranged. When the shoe mold on the shoe mold turntable rotates to the front of the demoulding device, it will stop, and then the sole will be taken out from the shoe mold through the cooperation of the mold opening component 2, the mold turning component 3 and the material taking mechanism 5. It has the advantages of reasonable structural design and high degree of automation.

[0026] Specifically, the material picking mechanism 5 includes a material picking arm 6 that can be bent and rotated, the upper end of the material picking arm 6 is connected to the frame 1, and the first material picking component 7 and the second material picking component 8 are arranged on the material picking arm 6. The first material picking component 7 and the second material picking component 8 approach or move away from the shoe mold through the bending and rotation of the material picking arm 6. Specifically, the material picking arm 6 includes an upper arm 9 and a lower arm 10, one end of the upper arm 9 is connected to an upper arm driving motor for driving the upper arm 9 to deflect, and the other end of the upper arm 9 is rotatably connected to the lower arm 10, and the frame 1 is provided with a lower arm driving motor connected to the lower arm 10 for driving the lower arm 10 to rotate relative to the upper arm 9.

[0027] The material picking arm 6 is connected to the frame 1, and can be a fixed connection or a movable connection. If it is a movable connection, before the material picking mechanism 5 works, the material picking mechanism 5 as a whole can adjust its relative position with the shoe mold through the movable characteristics of the material picking arm 6, which is convenient for subsequent grabbing. The material picking arm 6 is mainly used to adjust the position of the first material picking component 7 and the second material picking component 8 relative to the shoe mold. Specifically: the upper arm driving motor drives the upper arm 9 to rotate toward the side of the shoe mold, so that the first material picking component 7 and the second material picking component 8 are close to the shoe mold, and then the lower arm driving motor drives the lower arm 10 to rotate toward the side of the shoe mold to finely adjust the position of the first material picking component 7 and the second material picking component 8.

[0028] The material picking arm 6 is provided with a station turntable 12 that rotates relative to the material picking arm 6, and the first material picking assembly 7 and the second material picking assembly 8 are connected to the station turntable 12. Specifically, the first material picking assembly 7 includes a first mechanical chuck 14 and a first connecting plate 15 connecting the first mechanical chuck 14 and the station turntable 12, and the second material picking assembly 8 includes a shock-absorbing substrate 16 connected to the station turntable 12, and a plurality of evenly distributed second mechanical chucks 17 are provided on the shock-absorbing substrate 16.

[0029] The workstation turntable 12 is driven by a motor to rotate relative to the material picking arm 6. The workstation turntable 12 rotates to adjust the first material picking component 7 or the second material picking component 8 toward the shoe mold. The first mechanical chuck 14 in the first material picking component 7 is used to grab the sole, and the second mechanical chuck 17 in the second material picking component 8 is used to grab the sprue waste on the shoe mold.

[0030] In this embodiment, the first mechanical chuck 14 and the second mechanical chuck 17 have the same structure. Each mechanical chuck includes a chuck cylinder and two jaws driven by the chuck cylinder. The two jaws are hinged to each other at the middle position. The upper ends of the two jaws are respectively hinged with jaw support rods. The two jaw support rods are connected to the piston rod of the chuck cylinder through a jaw block. The two jaws of the mechanical chuck are retracted and opened by the chuck cylinder.

[0031] The mechanical chuck can also be any manipulator on the market that can control the closing and opening actions through a computer program. The number of the first mechanical chuck 14 and the second mechanical chuck 17 can be set according to the length of the sole and the amount of waste water inlet.

[0032] The shock-absorbing substrate 16 includes an upper substrate and a lower substrate. The upper substrate is fixedly connected to the workstation turntable 12. The lower substrate is provided with guide posts that can be inserted into the upper substrate. Each guide post is provided with a shock-absorbing spring. The top of the upper substrate is provided with a limit sleeve for limiting the movement of the guide post. The shock-absorbing substrate 16 plays a shock-absorbing role for the mechanical chuck in the second material-picking component 8. Since the mechanical chuck in the second material-picking component 8 will contact the outer surface of the shoe mold, and since the outer surface of the shoe mold is relatively hard, when there is no shock-absorbing substrate 16, the contact between the two will directly cause wear. When the mechanical chuck in the second material-picking component 8 contacts the outer surface of the shoe mold, the lower substrate will deviate upward to a certain extent. When the mechanical chuck is separated from the outer surface of the shoe mold, the lower substrate will be reset under the action of the shock-absorbing spring.

[0033] In this embodiment, the mold opening assembly 2 includes a mold opening base 19 arranged on the frame 1, and the mold opening base 19 is provided with an unlocking baffle 20 and a mold opening baffle 21 that can move vertically up and down, and a limiting baffle 22 that can move horizontally.

[0034] The vertical movement of the unlocking baffle 20 and the mold opening baffle 21 is driven by vertically arranged cylinders or oil cylinders or motors, and the horizontal movement of the limit baffle 22 is driven by oil cylinders or cylinders or motors. Specifically, in order to make the mold opening assembly 2 work more stably, two limit baffles 22 and mold opening baffles 21 are generally set, acting on both sides of the shoe mold respectively.

[0035] When the shoe mold that needs to be opened is a double-layer mold, the shoe mold is composed of a bottom mold and an upper mold. The overall working principle of the mold opening assembly 2 is: when the shoe mold reaches the specified position, the limit baffle 22 first moves horizontally to fix the bottom mold in the shoe mold to prevent the shoe mold from moving up and down as a whole, and then the unlocking baffle 20 moves upward to pull the lock to unlock the upper mold and the bottom mold of the shoe mold. At the same time, the mold opening baffle 21 moves upward to push the upper mold and the bottom mold of the shoe mold to separate.

[0036] In this embodiment, the mold turning assembly 3 includes a mold turning base 23 arranged on the frame 1, and an upper flip arm 24 is arranged on the mold turning base 23. The upper end of the upper flip arm 24 is rotatably connected to the flip base, and the lower end of the upper flip arm 24 is connected to a rotatable lower flip arm 25. The lower end of the lower flip arm 25 is provided with a flip piece 26. The overall working principle of the upper flip arm 24 and the lower flip arm 25 is the same as the working principle of the material taking arm 6. In this embodiment, the flip piece 26 is a flip hook, and a hanging rod for hanging the flip hook is arranged on the upper template of the shoe mold.

[0037] A double-layer mold sole demoulding method comprises the following steps: 1: Shoe mold opening: When the shoe mold is a double-layer mold, after the shoe mold enters the workstation, the mold opening component works to limit and fix the bottom mold of the shoe mold, then unlocks the lock of the shoe mold and pushes the upper mold of the shoe mold upward, releasing the upper mold of the shoe mold to separate it from the bottom mold of the shoe mold; 2: Shoe mold flipping: After the upper mold plate of the shoe mold is released, the mold flipping component works to flip the upper mold plate of the shoe mold so that the angle between the upper mold plate and the shoe mold is greater than 90 degrees, and the sole in the bottom mold is completely exposed; 3: Sole material extraction: After the sole in the bottom mold is completely exposed, the material extraction mechanism rotates toward the shoe mold to grab the sole. After grabbing the sole, the material extraction mechanism rotates away from the shoe mold to release the sole; 4: Shoe mold reset: After the material taking mechanism grabs the sole, the mold turning component resets the upper mold plate to cover the bottom mold plate of the shoe mold. During the reset process, the mold opening component resets the lock of the shoe mold; 5: Waste cleaning: After the shoe mold is reset, the material taking mechanism rotates toward the shoe mold to grab the sprue waste on the top of the shoe mold upper template.

[0038] The above five steps are a complete double-layer mold sole demoulding process. After the sprue waste on the top of the shoe mold upper template is grabbed, the shoe mold turntable rotates to move the next shoe mold to be taken out to the designated position, and the demoulding equipment works in a cycle according to the above steps.

[0039] Embodiment 2 Based on the structure of the original embodiment 1, the difference between embodiment 2 and embodiment 1 is that: Combination Figures 2 to 5 As shown, the frame is also provided with a material ejector assembly 4, which includes a material ejector 18. The body of the material ejector 18 is fixed on the frame 1, and the working part of the material ejector 18 can move up and down relative to the body so as to press the sole of the shoe mold from top to bottom and leave it in the shoe mold. Specifically, the material ejector 18 can be a cylinder or an oil cylinder, and the working part of the material ejector 18 is a piston rod.

[0040] When the shoe mold that needs to be opened is a three-layer mold, the shoe mold is composed of a bottom mold, a middle mold and an upper mold. The overall working principle of the mold opening assembly 2 is: when the shoe mold reaches the specified position, the limit baffle 22 first moves horizontally to fix the middle mold in the shoe mold to prevent the shoe mold from moving up and down as a whole, and then the unlocking baffle 20 moves upward to pull the lock to unlock the upper mold of the shoe mold and the shoe mold. At the same time, the mold opening baffle 21 moves upward to push the upper mold and the middle mold of the shoe mold to separate.

[0041] In this embodiment, the flip member 26 is a flip hook, and the upper mold plate and the middle mold plate of the shoe mold are provided with hanging rods for hanging the flip hook.

[0042] A three-layer mold sole demoulding method comprises the following steps: 1: Shoe mold opening: When the shoe mold is a three-layer mold, after the shoe mold enters the workstation, the mold opening component works to limit and fix the middle mold plate of the shoe mold, then unlocks the lock of the shoe mold and pushes the upper mold plate of the shoe mold upward, releasing the upper mold plate of the shoe mold to separate it from the middle mold plate of the shoe mold; 2: Initial mold flipping: After the upper mold plate of the shoe mold is released, the mold flipping assembly works to flip the upper mold plate of the shoe mold so that the angle between the upper mold plate and the shoe mold is greater than 90 degrees, and the sole inside the shoe mold is exposed; 3: Positioning and flipping the mold: After the sole in the shoe mold is exposed, the ejector assembly works to press the sole in the shoe mold down and leave it in the bottom mold of the shoe mold, the mold opening assembly resets, and the flipping assembly works to flip the middle mold plate of the shoe mold toward the upper mold plate, so that the angle between the middle mold plate and the bottom mold is greater than 90 degrees, and the sole in the bottom mold is completely exposed; 4: Sole material extraction: After the sole in the bottom mold is completely exposed, the material extraction mechanism rotates toward the shoe mold to grab the sole. After grabbing the sole, the material extraction mechanism rotates away from the shoe mold to release the sole; 5: Shoe mold reset: After the material taking mechanism grabs the sole, the mold turning component resets the middle mold and the upper mold in turn to cover the bottom mold of the shoe mold. During the reset process, the mold opening component resets the lock of the shoe mold; 6: Waste cleaning: After the shoe mold is reset, the material taking mechanism rotates toward the shoe mold to grab the sprue waste on the top of the shoe mold upper template.

[0043] The above 6 steps are a complete demoulding process for a three-layer mold sole. After the sprue waste on the top of the shoe mold upper template is grabbed, the shoe mold turntable rotates to move the next shoe mold to be removed to the designated position, and the demoulding equipment works in a cycle according to the above step direction.
