[0002] The rubber-coated mold is actually a secondary injection molding, which is to place the molded part in the mold for re-injection molding, so as to form a layer of rubber on the outer surface of the molded part.

However, in the manufacturing process, the air inlet net is easily squeezed and deformed during the transfer process of the workstation, which often leads to the shape of the air inlet net sent to the mold not matching the shape of the insert.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0017] Secondly, the horizontal frame in the present invention is adsorbed by the magnet block on the longitudinal plate and the magnetic arm fixedly installed on the horizontal frame. When the leveling bottom mold cooperates with the leveling top mold to fix the position of the horizontal frame, the rotation of the rotating table separates the horizontal frame at the pre-leveling device from the magnetic arm. The shortening of the distance between the next magnetic arm and the horizontal frame fixed by the pre-leveling device shortens the length of the telescopic rod. The movement of the movable rod of the telescopic rod relative to the fixed sleeve cooperates with the rotation of the driving cam of the driving assembly to drive the leveling bottom mold to vibrate, thereby reducing the number of electrical components while also ensuring that during the rotation of the rotating table, the pre-leveling device automatically completes the process of flattening the air inlet net in the flip placement table and eliminating internal stress, thereby improving efficiency.

Therefore, when the first linear drive drives the lifting platform to move up to make the leveling bottom mold enter the placement hole groove, the second piston rod moves up to a position in the same straight line with the fixed sleeve. Therefore, when the telescopic rod is shortened, the movable rod drives the parallel top plate to move toward the second piston rod, thereby promoting the movement of the first piston rod to achieve the vibration of the leveling bottom mold.

DETAILED DESCRIPTION

[0032] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] Reference Figures 1 to 12 :

[0034] A device for coating a mold for an air inlet net of a hair dryer comprises a base 1 and a rotating table 2 vertically mounted on the base 1, a first rotating driver 11 for driving the rotating table 2 to rotate is arranged on the base 1, a plurality of horizontal shelves 21 are slidably mounted on the top of the rotating table 2, a flipping and placing table 22 is rotatably mounted on one end of the horizontal shelf 21 away from the rotating table 2, a placement hole groove 221 for placing the air inlet net is arranged on the flipping and placing table 22, and the rotation of the rotating table 2 drives the flipping and placing table 22 to pass through the air inlet net feeding device, the pre-leveling device 3 and the coating mold 4 in sequence; the pre-leveling device 3 comprises a flattening bottom mold 31 located below the flipping and placing table 22 and a flattening top mold 32 located above the flipping and placing table 22, and the flattening bottom mold 31 and the flattening top mold 32 are arranged along The rubber-coated mold 4 includes a rubber-coated bottom mold 41 located below the flipping platform 22 and a rubber-coated top mold 42 located above the flipping platform 22. The flipping platform 22 is flipped to allow the air inlet net to enter the rubber-coated bottom mold 41.

[0035] When the air inlet net rubber encapsulation mold device of the present invention is in use, the staff manually or uses the air inlet net loading device to load the air inlet net, and the air inlet net is placed in the placement hole groove 221 of the flip placement table 22, and the placement hole groove 221 passes through the flip placement table 22 from top to bottom, and then the first rotary driver 11 drives the rotating table 2 to rotate, so that the flip placement table 22 with the air inlet net installed moves to the pre-leveling device 3. The first rotary driver 11 in this embodiment can be a servo motor, and the first rotary driver 11 can cooperate with the transmission structure such as the gear set to drive the rotating table 2 to rotate around the vertical axis; the first linear driver 341 of the pre-leveling device 3 starts to drive the lifting platform 34 to move up, and the mounting platform 33 and the leveling bottom mold 31 on the lifting platform 34 move up synchronously until the leveling bottom mold 31 enters the placement hole groove 221 from below the placement hole groove 221 and sticks to it. The lower side of the air inlet net is closed. The first linear drive 341 in this embodiment can be a cylinder, an oil cylinder or an electric push rod, etc. Similarly, the leveling top mold 32 can also be installed on the cylinder, the oil cylinder or the electric push rod to move downward, and the leveling top mold 32 is placed on the upper side of the air inlet net in the hole groove 221. The leveling bottom mold 31 and the leveling top mold 32 press and level the air inlet net to ensure that the shape of the air inlet net can match the rubber-coated bottom mold 41 when entering the rubber-coated bottom mold 41 of the rubber-coated mold 4. The leveling bottom mold 31 in this embodiment is installed on the mounting platform 33, and the cam 35 on the lifting platform 34 is in contact with the mounting platform 33. When the cam 35 rotates, it can drive the mounting platform 33 and the leveling bottom mold 31 to move back and forth in the vertical direction, so that the leveling bottom mold 31 can vibrate the bottom of the air inlet net, eliminate the internal stress of the air inlet net, and is beneficial to the leveling of the air inlet net. After the leveling is completed, the leveling bottom mold 31 and the leveling top mold 32 are separated from the placement hole groove 221 of the flip placement table 22, and the rotating table 2 rotates to move the leveled air inlet net to the top of the rubber-coated bottom mold 41 of the rubber-coated mold 4, and the flip placement table 22 flips 180 degrees, so that the air inlet net originally above the placement hole groove 221 falls into the rubber-coated bottom mold 41 for subsequent rubber-coating operations.

[0036] In order to solve the problem of how to realize the rotation of the cam 35 to drive the flattening bottom mold 31 to vibrate the air inlet net, the following features are specifically set:

[0037] The horizontal frame 21 extends radially along the rotating table 2, and horizontal shafts 222 are arranged on both sides of the flipping and placing table 22. The axis of the shaft 222 is perpendicular to the length direction of the horizontal frame 21. The flipping and placing table 22 is rotatably installed on the end of the horizontal frame 21 away from the rotating table 2 through the shaft 222. A second rotating driver 211 that drives the flipping and placing table 22 to rotate around the axis of the shaft 222 is arranged on one side of the horizontal frame 21. The working end of the second rotating driver 211 is connected to the shaft 222 of the flipping and placing table 22 in a transmission manner; a plurality of positioning sockets 223 are arranged on the upper and lower sides of the placement hole 221, and a positioning block 321 identical to the positioning socket 223 is arranged at the bottom of the leveling top mold 32. When the leveling top mold 32 enters the placement hole 221, the positioning block 321 is inserted into the positioning socket 223.

[0038] A longitudinal plate 212 is provided at the bottom of the horizontal frame 21, and a magnet block 213 is provided on the side of the longitudinal plate 212 facing the rotation direction of the turntable 2; the turntable 2 is provided with the same number of magnetic arms 23 as the horizontal frame 21, and the magnetic arms 23 are respectively provided on the side of each horizontal frame 21 facing the rotation direction of the turntable 2, and the magnetic arms 23 are parallel to the horizontal frame 21 and adsorbed with the magnet block 213; a telescopic rod 24 is installed on the side of the longitudinal plate 212 of the horizontal frame 21 away from the magnet block 213, and the other end of the telescopic rod 24 is connected to the magnetic arm 23 on one side of the adjacent horizontal frame 21, and the telescopic rod 24 is transmission-connected to the driving component 36 provided on the lifting platform 34 of the pre-leveling device 3, and the driving component 36 is used to drive the cam 35 to rotate.

[0039] The horizontal frame plate 21 in this embodiment extends radially along the rotating table 2 and is slidably installed on the rotating table 2. The horizontal frame plate 21 is adsorbed by the magnetic arm 23 fixedly installed on the horizontal frame plate 21 through the magnet block 213 on the longitudinal plate 212. Under normal conditions, the rotation of the rotating table 2 can drive the magnetic arm 23 and the horizontal frame plate 21 adsorbed together to move synchronously. The flipping and placing table 22 is rotatably installed at one end of the horizontal frame plate 21 through the shaft rods 222 on both sides. The working end of the second rotating driver 211 is connected to the shaft rod 222 of the flipping and placing table 22, so that the flipping and placing table 22 can be driven to rotate at the overmolding mold 4. When the flipping and placing table 22 moves to the pre-leveling device 3, the leveling top mold 32 moves downward until The positioning block 321 at the bottom of the leveling top mold 32 is inserted into the positioning socket 223 on the placement slot 221, and the leveling bottom mold 31 cooperates with the leveling top mold 32 to fix the position of the flip placement table 22 and the horizontal frame plate 21. The subsequent rotation of the rotating table 2 can only separate the horizontal frame plate 21 at the pre-leveling device 3 from the magnetic arm 23, and the next horizontal frame plate 21 entering the pre-leveling device 3 follows the magnetic arm 23 to move. During the movement, the length of the telescopic rod 24 between the two horizontal frames 21 is shortened, and the extension and retraction of the telescopic rod 24 serves as a power source and cooperates with the driving assembly 36 to drive the cam 35 to rotate, thereby realizing the reciprocating movement of the leveling bottom mold 31 in the vertical direction, and vibrating the bottom of the air inlet net to eliminate internal stress.

[0040] In order to solve the problem of how the extension and retraction of the telescopic rod 24 can serve as the power source of the driving assembly 36 to drive the cam 35 to rotate, the following features are specifically provided:

[0041] The telescopic rod 24 includes a coaxially arranged fixed sleeve 241 and a movable rod 242, the fixed sleeve 241 is fixedly connected to the mounting seat 214 arranged on the side of the longitudinal plate 212 away from the magnet block 213, and the movable rod 242 is provided with a hinge head 243 at one end away from the fixed sleeve 241, and a first limiting slide groove 231 is provided on the side of the magnetic arm 23 away from the magnet block 213, and the first limiting slide groove 231 extends along the length direction of the magnetic arm 23, and a slider 232 is slidably installed in the first limiting slide groove 231, and the slider 232 is hinged to the hinge head 243; the driving component 36 includes a piston cylinder 361 fixedly installed on the lifting platform 34, and the piston cylinder 361 is "V"-shaped, and a certain amount of liquid is filled in the piston cylinder 361. A certain amount of hydraulic oil is supplied to the piston cylinder 361. The first piston rod 362 and the second piston rod 363 are respectively inserted at both ends of the piston cylinder 361. The first piston rod 362 is perpendicular to the axis of the lifting platform 34, and the second piston rod 363 is parallel to the axis of the first limiting slide groove 231; the first piston rod 362 is fixedly connected to a rack 364 at one end outside the piston cylinder 361, and the rack 364 is meshed with a driving gear 351 coaxially mounted on the cam 35; the second piston rod 363 is provided with a vertically extending top plate 365 at one end outside the piston cylinder 361, and the movable rod 242 of the telescopic rod 24 is fixedly connected to the parallel top plate 244, and the parallel top plate 244 extends parallel to the fixed sleeve 241 and fits the top plate 365.

[0042] The driving assembly 36 in this embodiment includes a "V"-shaped piston cylinder 361, and a certain amount of hydraulic oil is filled in the piston cylinder 361, so that the first piston rod 362 and the second piston rod 363 at both ends move synchronously. The first piston rod 362 at one end of the piston cylinder 361 is connected to the rack 364, and the rack 364 is meshed with the driving gear 351 coaxially installed on the cam 35. Therefore, the piston cylinder 361 drives the rack 364 to move, which can drive the driving gear 351 and the cam 35 to rotate synchronously, driving the leveling bottom mold 31 to vibrate, and the second piston rod 363 moves in the piston cylinder 361. The movable rod 242 is kept parallel to the fixed sleeve 241 of the telescopic rod 24. When the first linear driver 341 drives the lifting platform 34 to move upward so that the flattened bottom mold 31 enters the placement hole groove 221, the second piston rod 363 moves upward to a position in the same straight line with the fixed sleeve 241. Therefore, when the telescopic rod 24 is shortened, the movable rod 242 moves in the fixed sleeve 241, and the movable rod 242 drives the parallel top plate 244 to move toward the second piston rod 363, and the parallel top plate 244 presses the top plate 365 at the top of the second piston rod 363, so that the second piston rod 363 is pressed. 63 moves toward the inside of the piston cylinder 361, thereby pushing the movement of the first piston rod 362 to realize the vibration of the flattening bottom mold 31. In this embodiment, the length of the telescopic rod 24 is shortened by shortening the distance between the magnetic arm 23 and the horizontal frame plate 21 fixed by the pre-leveling device 3. The movable rod 242 of the telescopic rod 24 moves relative to the fixed sleeve 241 to cooperate with the rotation of the driving assembly 36 to drive the cam 35 to drive the flattening bottom mold 31 to vibrate, thereby reducing the number of electrical components and ensuring that the pre-leveling device 3 automatically completes the flipping during the rotation of the rotating table 2. The process of flattening the air inlet net in the placement table 22 and eliminating the internal stress improves efficiency; in this embodiment, the fixed sleeve 241 of the telescopic rod 24 is installed on the mounting seat 214 on one side of the longitudinal plate 212 to ensure the fixation of the inclination angle between itself and the longitudinal plate 212, and the hinge head 243 on the movable rod 242 is hinged to the slider 232 slidably installed in the first limiting slide groove 231 on one side of the first limiting slide groove 231, so that it can be ensured that when the magnetic arm 23 moves toward the horizontal frame plate 21 fixed by the pre-leveling device 3, the telescopic rod 24 can be extended and retracted along the axis of the fixed sleeve 241.

[0043] In order to solve the problem of how to ensure the stable movement of the parallel top plate 244, the following features are specifically set:

[0044] The longitudinal plate 212 is provided with a through hole 215 which is inclined along the length direction of the parallel top plate 244 , and the parallel top plate 244 is inserted into the through hole 215 .

[0045] The parallel top plate 244 in this embodiment is inserted into the through hole 215 provided on the longitudinal plate 212 to guide the movement of the parallel top plate 244 and prevent the parallel top plate 244 from bending.

[0046] In order to achieve the purpose of automatically resetting the horizontal frame 21 to fit the magnetic arm 23, the following features are specifically provided:

[0047] A first spring 245 is sleeved on the movable rod 242 , and the first spring 245 elastically connects the fixed sleeve 241 and the hinge joint 243 .

[0048] In this embodiment, a first spring 245 is sleeved on the movable rod 242. When the movable rod 242 drives the parallel top plate 244 to push the second piston rod 363, the first spring 245 is compressed. When the leveling of the air inlet net is completed, the first linear driver 341 drives the lifting platform 34 to move downward, so that the leveling bottom mold 31 is separated from the placement hole groove 221 of the flip placement table 22. At this time, the driving assembly 36 also moves downward, and the top plate 365 moves down to a position where it does not contact the parallel top plate 244. Then the leveling bottom mold 31 moves upward to release the horizontal frame plate 21 and the flip placement table 22. The elastic force of the first spring 245 can make the fixed sleeve 241 move relative to the movable rod 242, driving the horizontal frame plate 21 to move to the side of the separated magnetic suction arm 23 until the magnet block 213 is re-adsorbed with the magnetic suction arm 23 and moves synchronously with the magnetic suction arm 23.

[0049] In order to solve the problem of how to make the second piston rod 363 of the driving assembly 36 automatically reset when it is released from the pressure of the parallel top plate 244, the following features are specifically provided:

[0050] A partition plate 366 is provided at one end of the first piston rod 362 located outside the piston cylinder 361, and an extension rod 367 parallel to the first piston rod 362 is provided on the side of the partition plate 366 away from the first piston rod 362. The extension rod 367 is inserted into the guide seat 342 set on the lifting platform 34, and a second spring 368 is sleeved on the extension rod 367. The second spring 368 elastically connects the guide seat 342 and the partition plate 366.

[0051] In this embodiment, a partition plate 366 is provided at one end of the first piston rod 362 away from the piston cylinder 361, and the extension rod 367 on the partition plate 366 is inserted in the guide seat 342 of the lifting platform 34 to keep parallel with the axis of the first piston rod 362. Therefore, when the second piston rod 363 moves into the piston cylinder 361 and pushes the first piston rod 362 to move outward, the partition plate 366 moves toward the side of the guide seat 342 and compresses the second spring 368 on the extension rod 367. When the first linear drive 341 drives the lifting platform 34 to move down until the top plate 365 is separated from the parallel top plate 244, the elastic force of the second spring 368 pushes the partition plate 366 to make the first piston rod 362 move into the inside of the piston cylinder 361, and pushes the second piston rod 363 to automatically reset, thereby ensuring smooth subsequent processing.

[0052] In order to solve the problem of how to stabilize the moving path of the leveling bottom mold 31 when it vibrates in the vertical direction, the following features are specifically set:

[0059] Working principle: When in use, the staff manually or by using the air inlet net loading device to load the air inlet net, the air inlet net is placed in the placement slot 221 of the flip placement table 22, then the first rotary driver 11 drives the rotary table 2 to rotate, so that the flip placement table 22 with the air inlet net installed moves to the pre-leveling device 3, the first linear driver 341 of the pre-leveling device 3 starts to drive the lifting table 34 to move up, the installation table 33 on the lifting table 34 and the leveling bottom mold 31 are synchronously moved up until the leveling bottom mold 31 enters the placement slot 2 from below the placement slot 221. 21 is fitted with the lower side of the air inlet net, the flattening top mold 32 is fitted with the upper side of the air inlet net in the hole groove 221, the flattening bottom mold 31 and the flattening top mold 32 press and flatten the air inlet net, the flattening bottom mold 31 cooperates with the flattening top mold 32 to fix the position of the flip placement table 22 and the horizontal frame plate 21, and the subsequent rotation of the rotating table 2 can only separate the horizontal frame plate 21 at the pre-leveling device 3 from the magnetic arm 23, and the next horizontal frame plate 21 entering the pre-leveling device 3 moves with the magnetic arm 23. During the movement, the telescopic rod 24 between the two horizontal frames 21 The length of the telescopic rod 24 is shortened, and the extension and retraction of the telescopic rod 24 serves as a power source to cooperate with the driving assembly 36 to drive the cam 35 to rotate. When the leveling of the air inlet net is completed, the first linear driver 341 drives the lifting platform 34 to move downward, so that the leveling bottom mold 31 is separated from the placement hole groove 221 of the flip placement table 22, and then the leveling bottom mold 31 moves upward to release the horizontal shelf 21 and the flip placement table 22. The elastic force of the first spring 245 can make the fixed sleeve 241 move relative to the movable rod 242, driving the horizontal shelf 21 to move to the side of the separated magnetic suction arm 23. Until the magnet block 213 is adsorbed onto the magnetic arm 23 again and moves synchronously with the magnetic arm 23 toward the rubber-coated mold 4, the second linear drive 411 starts to push the rubber-coated bottom mold 41 to move radially along the rotating table 2 to the bottom of the flipping and placing table 22. After the second rotary drive 211 drives the flipping and placing table 22 to flip around the axis of the shaft 222, the air inlet net in the placement hole 221 falls accurately into the rubber-coated bottom mold 41. Then the second linear drive 411 drives the rubber-coated bottom mold 41 to reset, and the rubber-coated top mold 42 is buckled on the rubber-coated bottom mold 41 for subsequent rubber-coating processing.
