Description

Technical Field

[0001] The present application relates to the technical field of switch seat injection molding, and in particular to an automatic injection molding auxiliary device for a switch seat. Background Art

[0002] At present, in the production process of the switch seat, the insulating plastic switch seat is mostly formed by injection molding and demoulding, and a thread needs to be opened in one half of the switch seat to facilitate the threaded connection of the other half of the switch seat.

[0003] Reference Figure 1 , usually, the way to open the thread in the switch seat 7 is to install a mold needle on the injection mold. Before the switch seat 7 is demolded by injection molding, the nut member 75 is manually put on the mold needle. Then the switch seat 7 is formed by injection molding using the injection mold, and the mold needle is injection molded to form a fixing hole 73, so that the nut member 75 is directly formed in the fixing hole 73, so that the other half of the switch seat 7 can be threadedly connected. The nut member 75 includes a threaded column 751 and a nut 752 integrally formed on the threaded column 751. The nut 752 is fixed in the fixing hole 73. The threaded column 751 is hollow and has threads, so that the other half of the switch seat 7 can be threadedly connected to the threaded column 751 by bolts, so that the two halves of the switch seat 7 are fixed.

[0004] The inventor believes that it is rather troublesome to manually put a plurality of nut pieces on the molding needle, which results in a low injection molding and demolding efficiency of the switch seat. Summary of the invention

[0005] In order to improve the injection and demoulding efficiency of a switch seat, the purpose of the present application is to provide an automatic injection auxiliary device for a switch seat.

[0006] The switch seat automatic injection molding auxiliary device provided in this application adopts the following technical solution:

[0007] A switch seat automatic injection molding auxiliary device comprises a frame, a feeding mechanism arranged beside the frame, and a clamping mechanism arranged on the frame, wherein the clamping mechanism comprises a clamping seat slidably arranged on the frame, a plurality of clamping claws arranged on the clamping seat, a plurality of feeding members arranged on the clamping seat, and a driving assembly arranged on the frame, wherein the feeding mechanism is used to place a nut member for clamping by the clamping claws, the feeding member comprises a push rod arranged on the clamping seat and located between the clamping claws, a sleeve slidably sleeved on the push rod, and a cylinder 1 arranged on the clamping seat to drive the sleeve to slide, wherein the driving assembly is used to drive the clamping seat to slide and then drive the clamping claw and the push rod to slide toward the molding needle, so as to extend the push rod into the nut member, and under the drive of the cylinder 1, the sleeve is driven to abut the nut member against the molding needle.

[0008] By adopting the above technical solution, when the nut is fed onto the mold needle, the feeding mechanism automatically transports the nut to one side of the clamp, the driving assembly drives the clamp and the clamp seat to slide to one side of the feeding mechanism, and then the clamp opens, and the driving assembly drives the clamp and the clamp seat to slide toward the feeding mechanism, so that the push rod extends into the nut. Then the clamp clamps the nut on the push rod, and the driving assembly is started again to move the clamp and the push rod to the mold together, so that the push rod and the mold needle are aligned. Then the driving assembly drives the clamp and the push rod to slide toward the mold needle, and at the same time the clamp opens and the cylinder drives the sleeve to slide toward the mold needle, so that the sleeve pushes the nut toward the mold needle, so that the nut is gradually and completely inserted into the mold needle, so as to realize the automatic insertion of the nut into the mold needle. Therefore, by setting the coordination between the clamping jaw and the ejector rod, the driving assembly is used to drive the clamping jaw and the ejector rod to slide, the nut piece is put on the ejector rod and then transferred to be aligned with the mold needle, and the nut piece on the ejector rod is pushed by the cylinder 1, so that the sleeve pushes the nut piece onto the mold needle under the drive of the driving assembly, so that the nut piece is automatically put on the mold needle, shortening the time required for the nut piece to be put on the mold needle, thereby improving the injection molding and demolding efficiency of the switch seat.

[0009] Optionally, the driving assembly includes a transverse moving member horizontally slidably arranged on the frame, a longitudinal moving member horizontally slidably arranged on the transverse moving member, and a vertical moving member vertically slidably arranged on the longitudinal moving member, the sliding directions of the transverse moving member and the longitudinal moving member are perpendicular to each other, and the clamping seat is arranged on the vertical moving member.

[0010] By adopting the above technical solution, when the driving assembly drives the clamping jaw and the push rod to move, the transverse moving member drives the longitudinal moving member, the vertical moving member, and the clamping seat to slide toward the feeding mechanism, so that the clamping jaw moves to the feeding mechanism, so that the feeding mechanism delivers the nut member to the clamping jaw and clamps it, and then the transverse moving member drives the clamping seat and the clamping jaw to move above the mold needle, and then the vertical moving member drives the clamping seat to slide down, so that the nut member on the push rod and the mold needle are aligned. Then the longitudinal moving member is started, so that the clamping seat slides toward the mold needle, and under the contact of the sleeve, the mold needle is extended into the nut member, so that the clamping jaw and the push rod are automatically moved, so as to facilitate the transfer of the clamped nut member.

[0011] Optionally, a flap is hinged at the lower end of the vertical moving member, and a second cylinder is provided on the vertical moving member for driving the flap to flip. A suction cup is provided on one side of the flap, and the second cylinder is used to drive the flap to rotate from horizontal to vertical to direct the suction cup toward the switch seat after demolding.

[0012] By adopting the above technical solution, when the switch seat after injection molding is demolded, the piston rod of the second cylinder is extended to make the flap flip to vertical, the vertical moving part slides down to one side of the switch seat, and then the longitudinal moving part drives the clamping seat to slide toward the switch seat, so that the suction cup abuts against the switch seat. Then, after the switch seat is sucked tightly by the suction cup, the longitudinal moving part drives the clamping seat to slide in the direction away from the mold, so that the switch seat is sucked by the suction cup and then separated from the mold. After that, the piston rod of the second cylinder contracts, driving the flap to rotate to horizontal, and then the switch seat rotated to horizontal is put down by the vertical moving part. Therefore, by setting the flap, the suction cup and the second cylinder, the injection molded switch seat is adsorbed by the suction cup, and the flap is driven to flip by the second cylinder, so that the switch seat after adsorption rotates under the flipping of the flap, so as to adjust the angle of the switch seat, thereby facilitating the placement of the switch seat after taking it out.

[0013] Optionally, the feeding mechanism includes a feeding table arranged under the frame, a feeding rail arranged on the feeding table, and a vibration plate connected to the feeding rail at one end away from the feeding table. A discharge port for outputting nut parts is provided on the feeding table, and a discharge component for outputting a single nut part from the discharge port is provided in the feeding table.

[0014] By adopting the above technical solution, when the nut parts are automatically conveyed to the clamping jaws, the vibration plate vibrates to convey multiple nut parts to the discharge port through the feeding track in sequence, and then a single nut part is output from the discharge port through the discharge assembly, so that the clamping jaws can clamp the single nut part. Then, the discharge assembly will continue to output the next nut part from the discharge port, and the remaining nut parts will be sealed in the feeding track in sequence, thereby facilitating the clamping jaws to clamp the single nut part.

[0015] Optionally, the discharging assembly includes a loading plate that slides in the loading platform and a cylinder three that drives the loading plate to slide. The sliding direction of the loading plate is perpendicular to the conveying direction of the nut parts. The loading plate is provided with a plurality of storage troughs for the nut parts to be fed from the loading track. The discharge port and the loading track are staggered with each other. The loading platform is provided with a cylinder four that pushes the nut parts in the storage trough out of the discharge port.

[0016] By adopting the above technical solution, when the vibration plate transports the nut piece from the feeding track to the feeding platform, the single nut piece in the feeding track is transported to the storage slot of the feeding plate as the vibration plate vibrates. At this time, there is only one nut piece in the single storage slot. Then cylinder three is started to push the feeding plate to slide toward the discharge port, so that the storage slot slides off the feeding track and connects with the discharge port. At this time, the storage slot is aligned with cylinder four. Cylinder four is started again to push the nut piece in the storage slot to the discharge port until the nut piece is pushed out of the discharge port onto the ejector rod, thereby realizing the push-out of a single nut piece in the discharge platform. Therefore, by setting the cooperation of the feeding plate, cylinder three, and cylinder four, and utilizing the alignment of the storage slot with the feeding track and the discharge port respectively, a single nut piece can be pushed out by cylinder four after entering the discharge slot, thereby facilitating the push-out of a single nut piece in the feeding track onto the ejector rod.

[0017] Optionally, the frame is provided with a rubber cutting mechanism for cutting off excess rubber on the switch seat, the rubber cutting mechanism includes a knife seat arranged on the frame, two hinged plates hinged and crossed in the knife seat, a blade fixed on the same end of the hinged plate to form a shearing edge, and a driving member arranged on the knife seat to drive the hinged plate to rotate and drive the blade to shear.

[0018] By adopting the above technical solution, after the nut is automatically installed in the switch seat, the second cylinder is used to drive the flap to rotate to a vertical position, so that the suction cup can suck the switch seat and remove it from the mold. After removal, the transverse member drives the clamping seat to move toward the knife seat. Then the switch seat is driven to move toward the blade, so that the blade extends into the switch seat, and the excess rubber formed in the switch seat during injection molding is located between the blades. Then the driving member is started, and the driving member drives the hinged plate to rotate, so that the blade is sheared to cut off the excess rubber in the switch seat, thereby facilitating the removal of the excess rubber formed during injection molding of the switch seat.

[0019] Optionally, the driving member includes a cylinder five which is arranged on the knife seat and drives the hinged plates to move closer to or away from each other.

[0020] By adopting the above technical solution, when the hinged plate is driven to rotate and drive the blade to shear, the cylinder five corresponding to the hinged plate is started, pushing the two hinged plates to rotate, so that the ends of the hinged plates close to the cylinder five are brought closer to each other, and then the blade also forms a shear as the hinged plates move closer to each other, so as to cut off the excess rubber in the switch seat.

[0021] Optionally, the driving member also includes a cylinder six arranged on the knife seat, and the piston rod of the cylinder six is ​​provided with a push block that is pushed into the hinged plates, and the push block is gradually contracted in the direction away from the cylinder six, and a spring one is arranged between the hinged plates close to the blade, and the spring one is used to drive the hinged plates to rotate to open the blades, and the hinged plates are hinged side by side on the knife seat, and the push block is used to push the hinged plates into and drive the blades to approach each other to form shearing.

[0022] By adopting the above technical solution, when the hinged plate is driven to rotate and drive the blade to shear, the six piston rods of the cylinder extend to drive the push block to extend into the end of the hinged plate away from the blade, so that the end of the hinged plate away from the blade is pushed away from each other by the push block, and the spring is compressed, so that the end of the hinged plate close to the blade is brought closer to each other to drive the blade to shear. After shearing, the push block is separated from the hinged plate, and the spring acts on the hinged plate to open the blade to facilitate the next shearing of the rubber material. In this way, the power source required to drive the hinged plate to rotate is reduced, so that the blade can easily cut off the excess rubber material in the switch seat.

[0023] Optionally, the frame is provided with a pressing frame located below the clamping claw, the pressing frame is provided with a conveying component for automatically conveying the demoulded switch seat, the pressing frame is provided with a pressing plate for sliding in a vertical direction, the pressing frame is provided with a cylinder seven for driving the pressing plate to slide, the circumferential side wall of the pressing plate is gradually reduced in the direction away from the cylinder seven, and the pressing plate is used to slide into the switch seat to open the switch seat for shaping.

[0024] By adopting the above technical solution, after the excess rubber in the switch seat is cut off, the horizontal moving part drives the clamping seat to move above the pressing frame, and then the second cylinder retracts to drive the flap to rotate to the horizontal, so that the switch seat rotates to the horizontal. Then the vertical moving part drives the clamping seat to slide down, and the switch seat is placed horizontally on the conveying assembly, and then the suction cup releases the adsorption of the switch seat, so that the switch seat falls on the conveying assembly, and the switch seat is conveyed to the bottom of the pressing plate through the conveying assembly. Then start the seventh cylinder to drive the pressing plate to slide down into the switch seat, so that the pressing plate can stretch and shape the switch seat, reduce the concave generated when the switch seat is cooled, and thus improve the quality of the switch seat after demolding.

[0025] Optionally, a positioning plate is slidably provided on the pressing frame along the vertical direction, and the positioning plate is used to abut the switch seat after demoulding and block its transportation. The pressing frame is provided with a cylinder 8 for driving the positioning plate to slide.

[0026] By adopting the above technical solution, when the switch seat after demolding and degumming is cooled and shaped, the suction cup releases the switch seat and places the switch seat on the conveying assembly. At this time, cylinder eight is started to drive the positioning plate to slide down, and the conveying assembly conveys the switch seat to the positioning plate, so that the side wall of the switch seat abuts against the positioning plate to intercept the switch seat on the conveying assembly, and the switch seat is positioned so that the switch seat is located directly below the pressing plate, thereby facilitating the pressing plate to be accurately pressed into the switch seat to shape it.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] By setting the coordination between the clamping jaw and the ejector rod, the driving assembly is used to drive the clamping jaw and the ejector rod to slide, the nut piece is put on the ejector rod and then transferred to be aligned with the mold needle, and the nut piece on the ejector rod is abutted by the sleeve through the contraction of the cylinder 1, so that the sleeve puts the nut piece on the mold needle under the drive of the driving assembly, so that the nut piece is automatically put on the mold needle, and the time required for the nut piece to be put on the mold needle is shortened, thereby improving the injection molding demoulding efficiency of the switch seat;

The pressing frame 52 is fixed to the side wall of the demoulding box 31. A cylinder 521 is fixedly connected to the pressing frame 52 to drive the pressing plate 53 to slide up and down. The pressing plate 53 gradually shrinks downward in the vertical direction, so that the cylinder 521 drives the pressing plate 53 to slide down into the switch seat 7 on the conveying assembly 51. Since the switch seat 7 will produce a concave shrinkage phenomenon when it is cooled after injection molding, the pressing plate 53 is slid into the switch seat 7 to open the switch seat 7 until the switch seat 7 is cooled and fixed, thereby reducing the concave deformation of the switch seat 7.

Before the pressing plate 53 slides down, the positioning plate 54 slides down to intercept and position the switch seat 7 on the conveyor belt 513, so that the pressing plate 53 slides into the switch seat 7 for positioning.

[0083] The implementation principle of implementation 1 of the present application is as follows: when the nut member 75 is clamped, the motor 1 4112 drives the slide 1 4111 and the clamping seat 42 to slide to the top of the loading platform 23, and then the motor 3 4132 drives the clamping seat 42 and the clamping claw 43 to slide down to one side of the loading platform 23, so that the push rod 441 and the discharge port 231 are aligned. The vibration plate 24 transports the nut member 75 to the storage tank 264 through the loading track 25, and then the cylinder 3 262 drives the loading plate 261 to slide, so that the storage tank 264 slides to communicate with the discharge port 231, and then the cylinder 4 263 pushes the nut member 75 in the storage tank 264 out of the discharge port 231. Then the motor 2 4123 is started, driving the clamping seat 42 to slide toward the loading platform 23, so that the push rod 441 is inserted into one end of the nut member 75, and then the clamping jaw 43 clamps the nut member 75, and then the motor 3 4132 drives the clamping jaw 43 to move upward, and the motor 1 4112 drives the clamping jaw 43 to move above the demolding box 31. The motor 3 4132 is started to drive the clamping jaw 43 to slide down into the demolding box 31, and align the push rod 441, the nut member 75 and the molding needle 33. Then, the motor 2 4123 drives the clamping jaw 43 to move toward the mold needle 33, so that the mold needle 33 is inserted into the end of the nut part 75 away from the push rod 441. At this time, the cylinder 1 443 drives to push the slide plate 421, the sleeve 442, and the clamping jaw 43 to continue to slide toward the mold needle 33, so that the nut part 75 can slide completely onto the mold needle 33 after passing through the abutment of the sleeve 442, so that the nut part 75 can be automatically inserted into the mold needle 33.

[0084] After the switch seat 7 is injection molded in the demolding box 31, the piston rod of the second cylinder 451 is extended, so that the flap 45 rotates to a vertical position, and then the second motor 4123 drives the flap 45 to slide in a direction away from the mold needle 33, so that the suction cup 46 abuts against the switch seat 7 in the mold 32 and absorbs the switch seat 7, and then the second motor 4123 drives the flap 45 to slide in a direction close to the mold needle 33, absorbs the switch seat 7 and then separates it from the mold 32. Then, the third motor 4132 drives the flap 45 to move upward, and the first motor 4112 drives the flap 45 to move to the side of the knife seat 61 after the upward movement, so that the nozzle material 74 in the switch seat 7 and the blade 63 are aligned. Then the second motor 4123 is started to drive the switch seat 7 to move toward the knife seat 61, so that the blade 63 extends into the switch seat 7 and the nozzle material 74 is located between the blades 63. Then start the cylinder 5 641, the piston rod of the cylinder 5 641 extends to push the two ends of the hinged plate 62 closer to each other, and makes the blades 63 closer to each other to form a shearing action, so as to automatically shear the nozzle material 74.

[0085] Then the motor 2 4123 drives the flap 45 to slide away from the knife seat 61, so that the switch seat 7 slides away from the blade 63, and the motor 1 4112 drives the flap 45 to move above the conveying platform 511. At this time, the piston rod of the cylinder 2 451 contracts, driving the flap 45 to rotate to the horizontal, and then the motor 3 4132 drives the flap 45 to slide down, so that the switch seat 7 rotated to the horizontal falls on the conveyor belt 513, and the suction cup 46 releases the adsorption of the switch seat 7, so that the switch seat 7 is transported to the bottom of the pressing frame 52 under the conveyor belt 513. Then the cylinder 8 522 is started first to intercept and position the switch seat 7, so that the cylinder 7 521 is started, driving the pressing plate 53 to slide down into the switch seat 7, and the switch seat 7 is stretched open for cooling and shaping, until the shaping is completed, the piston rods of the cylinder 7 521 and the cylinder 8 522 are contracted, and the conveyor belt 513 automatically transports the switch seat 7. During the entire molding process, the nut member 75 is automatically sleeved on the molding needle 33 , which shortens the time required for the nut member 75 to be sleeved on the molding needle 33 , thereby improving the injection molding and demoulding efficiency of the switch seat 7 .

[0086] Embodiment 2:

[0087] Reference Fig.10 The difference between this embodiment and the first embodiment is that the two hinge plates 62 are hinged respectively, and the hinge axes of the two hinge plates 62 extend in the vertical direction. The hinge plates 62 gradually expand in the direction away from the blade 63, and the end of the hinge plates 62 away from the blade 63 is fixedly connected to the push plate 8, and the push plate 8 gradually shrinks in the direction away from the blade 63. The end of the hinge plates 62 close to the blade 63 is fixedly connected to the second spring 81, and the two ends of the second spring 81 are respectively fixedly connected to the hinge plates 62, so that the blades 63 abut against each other and the ends of the hinge plates 62 away from the blade 63 are close to each other through the elastic force of the second spring 81.

[0088] Reference Fig.10 The driving member 64 includes a push block 82 that slides between the two hinged plates 62 and a cylinder 6 83 that drives the push block 82 to slide. The push block 82 is gradually contracted in a direction away from the cylinder 6 83.

[0089] Reference Fig.10 After the piston rod of the cylinder 6 83 is extended, the push block 82 is driven to slide between the hinged plates 62, so that the end of the hinged plate 62 away from the blade 63 opens and the blades 63 move closer to each other, so that the blades 63 form a shearing operation.

[0090] The implementation principle of Example 2 of the present application is: a single cylinder 6 83 is used to drive the push block 82 to slide, so that after the push block 82 slides between the hinged plates 62, it drives the end of the hinged plates 62 away from the cylinder 6 83 to move closer to each other, so that the blades 63 move closer to each other to form shearing. After the sprue material 74 is sheared, the piston rod of the cylinder 6 83 contracts, the push block 82 slides away from the hinged plate 62, and the restoring force of the spring 2 81 acts on the hinged plate 62, so that the end of the hinged plate 62 away from the blade 63 moves closer and the blades 63 move away from each other, so as to save power source and complete the cutting of the sprue material 74.

[0091] Embodiment 3:

[0092] Reference Fig.11 The difference between this embodiment and the second embodiment is that the hinge axes of the two hinged plates 62 extend in the horizontal direction, and the two hinged plates 62 are respectively a fixed plate 622 with a fixed position and a rotatable movable plate 623. The end of the movable plate 623 away from the blade 63 is located below the fixed plate 622, and the movable plate 623 located below is longer than the fixed plate 622, and the weight of the end of the movable plate 623 away from the blade is greater than that of the fixed plate 622. The knife seat 61 is fixedly connected with a cylinder 99, and the piston rod of the cylinder 99 abuts against the hinged plate 62.

[0093] The implementation principle of the third embodiment of the present application is as follows: through the action of the cylinder 99, the movable plate 623 located below rotates upward, thereby driving the blade 63 to rotate downward, so that the two ends of the hinged plate 62 are brought close to each other, and then the blades 63 are brought close to each other to shear the nozzle material 74. After shearing, the piston rod of the cylinder 8522 contracts, so that the movable plate 623 rotates downward under gravity, so that the blades 63 rotate upward and automatically increase the distance between the two blades 63. This saves the use of the spring 281 and increases the spacing of the blades 63, thereby saving the space occupied by the cylinder driving the hinged plate 62.

[0094] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
